The Pillar Mountain High Penetration Wind Project is the integration and installation of three General Electric (GE) 1.5 megawatt (MW) wind turbines along with an energy storage system that allows the stable integration of high wind penetration rates onto KEA’s isolated grid. This project is the next step in a series of KEA’s renewable energy developments aimed at displacing the use of diesel fuel for electric generation which will allow KEA to achieve its vision to endeavor to produce 95% of energy Renewable Energy Fund Grant Application Round 5 AEA12-001 Grant Application Page 3 of 27 7/1//2011 sales with cost effective renewable power solutions by the year 2020. The energy storage system will regulate system frequency on a short‐term basis as the wind resource unpredictably comes and goes. Terror Lake will provide the long‐term, macro‐energy storage of wind energy on an annual basis. Therefore, the Pillar Mountain High Penetration Wind Project is not simply a wind turbine construction effort, but an innovative demonstration of how high penetration rates of wind can be stably integrated onto an isolated electric grid through the installation of a energy storage system that bridges Pillar Mountain’s variable wind energy resource with the Terror Lake Hydroelectric Project’s dispatchable hydropower. 2.5 PROJECT BENEFIT Briefly discuss the financial and public benefits that will result from this project, (such as reduced fuel costs, lower energy costs, etc.) The Pillar Mountain High Penetration Wind Project allows KEA to continue supplying Kodiak's electric needs with clean renewable energy as load demand grows. This project is the next step necessary for KEA to achieve its vision statement: Endeavor to produce 95% of energy sales with cost effective renewable power solutions by the year 2020. Achieving this vision benefits the Alaskan public by reducing Kodiak’s dependence on diesel fuel and providing a working model for other remote island communities looking to integrate high penetration wind on their isolated grid systems. It will also lower the electric cost for the community of Kodiak and other KEA cooperative members. In March 2011, KEA completed a Ten Year Load Forecast utilizing historical years 2001 through 2010 that indicates a load demand growth of 8.1% over the period of 2011 through 2020 (see Exhibit D). This continual growth of Kodiak’s electricity demand will put pressure on KEA's existing generating capacity, and would result in increased price and environmental pressure if diesel fuel continues to be utilized to keep up with total energy sales. While the Terror Lake Hydroelectric Project is the cornerstone to KEA’s renewable generation system, the Terror Lake reservoir only stores a limited amount of water available for generating kilowatt‐hours; additional wind energy is needed to supply more renewable kilowatt‐hours to KEA’s system. The Pillar Mountain High Penetration Wind Project is a cost‐effective approach for KEA to meet growing electrical demand by optimizing our existing wind‐hydro generation system. Installation of an energy storage system allows KEA to install three additional GE 1.5 MW wind turbines on Pillar Mountain, and mitigate the need to curtail energy production from KEA’s existing wind turbines. (Refer to Section 4.3.1 for detailed description of the energy storage system.) This expansion of KEA’s wind energy portfolio would minimize Kodiak’s dependence on costly diesel fuel. The estimated annual energy production of this project displaces up to 958,333 gallons of diesel fuel consumption annually. At KEA’s current price for diesel fuel ($3.32 per gallon), this project provides a direct annual benefit of up to $3,181,666 in avoided fuel costs alone. Considering the 20‐year life of the wind turbines and a conservative 3% inflation rate for the cost of fuel, this project can provide a total benefit of $85,492,575 just in avoided fuel costs. The net present value (NPV) of the Pillar Mountain High Penetration Wind Project is estimated at $44,391,641. This NPV analysis compares the cost of generating wind‐generated kilowatt‐hours versus diesel‐generated kilowatt‐hours over the 20‐year life of the project’s wind turbines. In the first year alone, the project is estimated to provide KEA with net savings of $2,522,506 by avoiding the high cost of diesel fuel, engine maintenance, and emissions management. Total savings over the 20‐ years adds up to $76,381,444. Additional information on the calculations and assumptions used to develop the financial benefits of this project is detailed in Section 5. Shifting Kodiak’s source of electric energy from diesel to fuel‐free renewables not only lowers the cost of power, it stabilizes the cost of power. The fewer gallons of diesel fuel KEA needs to consume for Renewable Energy Fund Grant Application Round 5 AEA12-001 Grant Application Page 4 of 27 7/1//2011 generating electricity, the less impact volatile fuel prices have on the Kodiak community, and the less pollution emitted from our diesel stacks. Minimizing fossil fuel emissions is a public health benefit itself, but it also buffers KEA from the costly obligations imposed by new air quality regulations that affect major polluters. The amount of diesel fuel displaced by the Pillar Mountain High Penetration Wind Project’s expanded wind capacity and grid frequency support prevents 10,782 tons per year of greenhouse gas emissions from entering the atmosphere and contributing to ocean acidification. To illustrate the magnitude of this public benefit, consider that reducing 10,782 tons of CO2 a year equates to taking 1,918 passenger cars of the road, diverting 3,408 tons of waste from the landfill for recycling, saving 2,086 acres of coniferous forest, or growing 250,802 tree seedlings for ten years. As fishing‐dependant community, Kodiak is very vulnerable to the impacts of ocean acidification caused by fossil fuel emissions, and it is KEA’s responsibility to generate power in a manner that is consistent with our community’s values. Providing reliable power at a predictable cost is a benefit KEA strives to provide to the Kodiak business community for future economic development. Expanding KEA’s renewable energy portfolio through the Pillar Mountain High Penetration Wind Project provides an extra benefit to Kodiak’s economy through new marketing opportunities for Alaskan businesses that use KEA’s renewably‐ based electricity to manufacture their products. In 2010, the Kodiak Chamber of Commerce received a grant from the Alaska Fisheries Development Foundation, Inc. and the Kodiak Island Borough for its "Salmon Wind Water" marketing campaign that brands Kodiak’s salmon products as sustainably‐ managed fish processed almost entirely with renewable energy. According to the Kodiak Chamber of Commerce’ website:1 “Local salmon processors are proud to be part of an electricity grid that is embracing clean energy and moving away from reliance on fossil fuel‐based diesel. KEA’s innovative use of wind and water resources has truly redefined Sustainable Seafood.” KEA currently allocates Renewable Energy Credits to Pacific Seafoods for the marketing of their Kodiak‐processed seafood, and to the US Coast Guard Base Kodiak to assist them in their Presidential Mandate on renewable energy usage. KEA must continue to develop its renewable energy resources so that growing loads continue to be supplied with renewable energy for the benefit of our community. The Pillar Mountain High Penetration Wind Project provides the needed kilowatt‐hours to meet growing load so that additional Renewable Energy Credits can benefit more Kodiak businesses. In terms of technological development for Alaska’s energy sector, KEA’s 2009 Pillar Mountain Wind Project provided a model for industry‐scale wind parks, which is helping to move other Alaska communities toward self‐reliance through reduced dependence on fossil fuels. GE is now working to install their state‐of‐the‐art wind turbine units at other Alaskan locations. With the High Penetration Wind Project, the Alaska public will continue to benefit from KEA’s research and implementation of innovative system stability solutions for integrating large amounts of variable renewable energy onto isolated electrical grid systems. KEA will continue to assist communities throughout Alaska and the world move toward greater energy independence by sharing lessons learned from this project. 1 http://www.kodiak.org/business/renewable.html Renewable Energy Fund Grant Application Round 5 AEA12-001 Grant Application Page 5 of 27 7/1//2011 2.6 PROJECT BUDGET OVERVIEW Briefly discuss the amount of funds needed, the anticipated sources of funds, and the nature and source of other contributions to the project. The total capital cost of the Pillar Mountain High Penetration Wind Project is $23,150,000. KEA is requesting $8,000,000 in grant funds for this project. The remaining funding of $15,150,000 will be funded by the KEA membership through the electric energy rate structures. Given the significant benefits of the project and KEA’s readiness to proceed, KEA intends to initiate preliminary work on the project prior to July 2012. The expense KEA expects to incur prior to July 2012 is estimated at $7,150,000, leaving $8,000,000 in KEA‐borne costs after July 2012. KEA has obtained a new Clean Renewable Energy Bond (CREB) allocation from the Internal Revenue Service. CoBank, ACB has been selected as the lender for these bond funds. Currently the US Treasury has set their bond term at 17 years. Considering the current interest rate subsidy provided by the US Treasury, KEA is estimating a 1.27% interest rate on the bond funds to be used to finance KEA’s portion of the total project cost. These new bond funds have not yet been advanced, so the interest rate could vary until the loan is finalized. 2.7 COST AND BENEFIT SUMARY Include a summary of grant request and your project’s total costs and benefits below.

The Milestones must also be included on your budget worksheet to demonstrate how you propose to manage the project cash flow. (See Section 2 of the RFA or the Budget Form.) Milestone 1 – Mobilization, Installation and Commissioning of Wind Turbines This phase of the construction project includes the purchase, transporting, installation and commissioning of the three GE 1.5 MW wind turbines atop Pillar Mountain. The construction of the 2009 Pillar Mountain Wind Project has prepared KEA for the extreme logistical challenge involved in transporting and installing these wind turbines in Kodiak Alaska. This milestone will also include all of the necessary interconnection to the KEA grid. Milestone 2‐ Mobilization, Installation and Commissioning of Energy Storage System This phase of the project will be to purchase, transport and install the energy storage system that will provide the short term energy storage needed to operate high wind penetration on an isolated grid. The energy storage system will allow KEA to have full utilization of the wind turbines. The energy storage system will be installed at the High Substation facilities. The new system will then need to be tuned and integrated onto the KEA grid.

Include any partnerships or commitments with other entities you have or anticipate will be needed to complete your project. Describe any existing contracts and the selection process you may use for major equipment purchases or contracts. Include brief resumes and references for known, key personnel, contractors, and suppliers as an attachment to your application. Given the success of KEA’s previous wind turbine installation in 2009, KEA intends to generally use the same contractors and equipment vendors for the wind turbine installation portion of the Pillar Mountain High Penetration Wind Project in 2012. • Tetra Tech EC, Inc. is the engineering and construction firm involved in the design for the civil infrastructure as well as the erection of the turbines. Detailed information on Tetra Tech EC, Inc.’s Statement of Qualifications for Wind Energy Services is included in Exhibit F. • Electric Power Systems, Inc./Dryden & LaRue Inc. is an Alaskan engineering firm involved in the design of the substation, the relay protection and the grid stability engineering. • KEA will remain the lead for the transmission and distribution design and installation. • Anderson Transport Services would be the turbine transport company. • GE is the turbine supplier and provider of support commissioning crew. The exact configuration of the wind energy storage system is still under examination. KEA is currently examining the Powercorp Powerstore flywheel system and the XP battery system. Information on these energy storage technologies are provided in Exhibit E. 3.5 Project Communications Discuss how you plan to monitor the project and keep the Authority informed of the status. To monitor the project’s budget, KEA’s accounting system will assign tracking numbers to the costs associated with each project milestone. As project manager, Darron Scott will provide milestone reports to the Engineering and Technology Committee of the KEA Board of Directors. KEA will provide updates to the community through the KEA website (www.kodiakelectric.com) and the monthly KEA NewsLine member newsletter. KEA will follow all provisions outlined by AEA in the Renewable Energy Fund Grant Agreement and provide quarterly updates on the project’s status. The Authorized Signers Form is provided on page 36. 3.6 Project Risk Discuss potential problems and how you would address them. This high penetration wind project involves two aspects; 1) adding three 1.5 MW wind turbines and 2) adding the appropriate sized energy storage device(s). In the first case, KEA has already built three wind turbines on Kodiak and mitigated the majority of the risks in this case. There is always a risk of transportation or turbine erection failure, but KEA will have a fixed price contract with the contractor that will help mitigate risk. KEA contractors will also be inspecting the wind turbines before they leave Seattle to mitigate the possible risk of a manufacturing defect. Other issues that were once considered for the construction of the wind turbines have been already mitigated through KEA’s prior experience. The energy storage system has its own risks. While these systems have been proven multiple times for supporting wind farms, there is still a possibility that they may not be modeled robustly enough for KEA’s unique grid configuration. This introduces a potential risk that the energy storage system may Renewable Energy Fund Grant Application Round 5 AEA12-001 Grant Application Page 10 of 27 7/1//2011 not provide the KEA grid with as much stability as initially expected. If this is the case, then KEA would curtail energy production from the wind turbines until the problem is remedied, which may be through the addition of more energy storage devices. The Pillar Mountain High Penetration Wind Project will demonstrate pioneering technology for Alaska’s unique isolated grid systems. Being a pioneer is not without risk, yet KEA is prepared to address any of the potential risks that may arise in this project. SECTION 4 – PROJECT DESCRIPTION AND TASKS • Tell us what the project is and how you will meet the requirements outlined in Section 2 of the RFA. • The level of information will vary according to phase(s) of the project you propose to undertake with grant funds. • If you are applying for grant funding for more than one phase of a project provide a plan and grant budget form for completion of each phase. • If some work has already been completed on your project and you are requesting funding for an advanced phase, submit information sufficient to demonstrate that the preceding phases are satisfied and funding for an advanced phase is warranted. 4.1 Proposed Energy Resource Describe the potential extent/amount of the energy resource that is available. Discuss the pros and cons of your proposed energy resource vs. other alternatives that may be available for the market to be served by your project. The superb wind resource of the Pillar Mountain site has been established by the successful operation of the previously installed wind turbines. The optimum installed capacity for KEA’s system is 4.5 MW of additional wind. This amount of wind energy matches our grid needs; system stability and load demand. The capacity factor for the Pillar Mountain High Penetration Wind Project turbines is estimated at 33%, which would supply an annual generation of approximately 13 million kilowatt‐hours. With the addition of an energy storage system, KEA would also be able to increase the productivity of the original wind turbines by about 800,000 kilowatt‐hours per year. This increase in productivity from existing wind turbine units is a result of lessening the need to curtail wind energy production for grid stability because the energy storage system would provide the needed grid stability. The energy storage system will either be a series of flywheels or batteries. The flywheel system that KEA is examining is the Powercorp Powerstore system as shown in Exhibit E. The flywheels have a large rotating mass hooked to a generator and then through a power inverter. Once the frequency dips (which can happen from a sudden drop in wind power) the energy from the flywheels is released onto the grid to give time for Terror Lake to react to the situation. The XP battery system shown in Exhibit E will work in the same way. These systems can react within milliseconds to system frequency problems. Besides wind, the only other practical energy resources for the Kodiak community at this time are hydropower and diesel. Diesel power has only one advantage over wind power in that it is dispatchable, while wind is not reliable on a minute‐to‐minute basis. All other factors for using diesel fuel as an energy resource are negative as compared to wind because diesel‐based generation is expensive, has no cost stability, and the emissions have a negative impact on the environment. Hydroelectric generation is a viable resource for Kodiak, and KEA continues to investigate options for developing local hydropower resources. The Terror Lake Hydroelectric Project operates very well for the community; however, there is a finite amount of water in the Terror Lake reservoir that can be utilized for hydropower production. KEA’s growing load demand requires more renewable energy to meet the energy needs of our community. The Pillar Mountain High Penetration Wind Project is the most cost‐effective approach for KEA to meet Renewable Energy Fund Grant Application Round 5 AEA12-001 Grant Application Page 11 of 27 7/1//2011 growing electrical demand by optimizing existing hydro‐wind infrastructure. When combined with the hydropower from the Terror Lake facility and the original wind turbines on Pillar Mountain, the Pillar Mountain High Penetration Wind Project is expected to supply KEA’s system with approximately 98% renewable energy. This project is the next necessary step toward KEA’s renewable energy vision. 4.2 Existing Energy System 4.2.1 Basic configuration of Existing Energy System Briefly discuss the basic configuration of the existing energy system. Include information about the number, size, age, efficiency, and type of generation. KEA operates an isolated electrical grid system. The main power source is the Terror Lake Hydroelectric Facility. KEA brought 4.5 MW of wind online in July of 2009 with the completion of the Pillar Mountain Wind Project. KEA also operates and maintains four independent diesel generation facilities (Kodiak Generating Station, Nyman Power Plant, Swampy Acres Plant and Port Lions) which are a mixture of diesel reciprocating engines and a diesel‐fired combined cycle generation unit. The following table details KEA’s current generation resources. The capacity numbers listed are high‐ end nominal values for the machines. This is a point where the machines can be operated on a high end for a period of time, but does not reflect total generating potential due to the detrimental effects of full load operations on diesel engines. Note that the efficiencies are for the load points mentioned at ideal conditions.

The additional capacity provided by the Pillar Mountain High Penetration Wind Project and the third turbine at Terror Lake are both generation projects designed to mitigate the use of diesel‐powered generation. KEA has over 32 miles of transmission lines and 343 miles of distribution lines. KEA has six substation facilities as itemized in the table below. The Pillar Mountain High Penetration Wind Project will add additional transformation at the High Substation.

Include a brief discussion of any impact the project may have on existing energy infrastructure and resources. The existing energy resources for KEA (as itemized in Section 4.2.1) are hydro, wind and diesel. KEA’s wind and hydro resources work in conjunction as an integrated renewable resource with electrical loads supplied first with available wind energy, and dispatchable hydropower backing it up. Production from the Terror Lake Hydroelectric Project is limited by the amount of water available. Historically, the hydro facility provides our community with a high average of 117 million kilowatt‐ hours annually. Extreme rain and/or high snow runoff can increase the total hydro generation capabilities, and dry years with low snowpack winters can decrease Terror Lake’s total annual generation. The upcoming installation of the third hydro turbine‐generator at Terror Lake will increase the plant’s capacity, but will not generate additional hydro kilowatt‐hours except through gained efficiencies and increased plant availability during maintenance in the high water level years. The wind energy provided by the Pillar Mountain High Penetration Wind Project is where the additional kilowatt‐ hours would need to be generated to meet KEA’s growing load demand. The new wind turbines will be designed to integrate with the same SCADA and control system as the 2009 wind turbines. The new wind energy storage system will compliment the 2009 wind turbines and stabilize KEA’s overall grid system for non‐wind events as well. Installation of the three additional wind turbines and the wind energy storage system are the next steps needed for KEA to achieve its renewable energy vision of supplying 95% of energy sales with cost‐ effective renewable power solutions. Without the Pillar Mountain High Penetration Wind Project, KEA remains dependant on diesel‐powered generation to supplement the existing wind‐hydro generation Renewable Energy Fund Grant Application Round 5 AEA12-001 Grant Application Page 13 of 27 7/1//2011 system under growing loads. 4.2.3 Existing Energy Market Discuss existing energy use and its market. Discuss impacts your project may have on energy customers. In 2010 the community of Kodiak utilized approximately 139 million kilowatt‐hours of electric energy. 2011 year‐to‐date sales indicate the community has increased electrical usage by approximately 1.6% this year. The membership base consists of 4,685 residential services that each consumes approximately 7,206 kilowatt‐hours annually, with slight increase in usage each year. The total annual energy usage of the large power consumers, and subsequently the energy usage of the entire system as a whole, is largely dependent on the fishing industry. Seafood‐processing accounts for approximately 25% of KEA’s electric sales annually. In March 2011, KEA completed a Ten Year Load Forecast utilizing historical years 2001 through 2010 (see Exhibit D) that indicates a predicted load demand growth of 8.1% over the period of 2011 through 2020. This forecast predicts a continual increase in both peak loads (i.e., capacity) and total sales (i.e., energy), which puts pressure on KEA's existing generating capacity. If diesel fuel continues to be utilized to keep up with total sales, KEA would be challenged with increased energy costs and environmental pressure. The Pillar Mountain High Penetration Wind Project is a cost‐effective approach for KEA to meet growing electrical demand by optimizing an existing wind‐hydro generation system. Diesel cost volatility from month to month makes it difficult for the Kodiak business community to plan future development or predict cost of future operations. Mitigating the highly unpredictable cost of diesel fuel in our energy generating portfolio would stabilize KEA’s cost of power. Constructing the Pillar Mountain High Penetration Wind Project provides the needed kilowatt‐hours for KEA to reach our renewable energy vision and stabilize the cost of power for the Kodiak community. 4.3 Proposed System Include information necessary to describe the system you are intending to develop and address potential system design, land ownership, permits, and environmental issues. 4.3.1 System Design Provide the following information for the proposed renewable energy system: • A description of renewable energy technology specific to project location • Optimum installed capacity • Anticipated capacity factor • Anticipated annual generation • Anticipated barriers • Basic integration concept • Delivery methods The Pillar Mountain High Penetration Wind Project consists of three GE 1.5 MW wind turbines with additional transformation at High Substation, as well as an appropriately sized wind energy storage system. The three GE 1.5 MW wind turbines will be nearly identical to the original three wind turbines currently operating on Pillar Mountain. An informational brochure for the new GE 1.5 SLE wind turbine model is provided in Exhibit E. Installing an additional 4.5 MW of wind energy on KEA’s isolated grid requires a new kind of energy storage system to bridge the gap between a drop in wind production and the pick‐up of hydro production from Terror Lake. Terror Lake provides the long‐term, macro‐scale storage of wind energy on an annual basis; however, this additional micro‐scale storage system is needed on a short‐term, 30 to 45 second basis. Since wind energy is intermittent and unpredictable, the short‐term wind energy Renewable Energy Fund Grant Application Round 5 AEA12-001 Grant Application Page 14 of 27 7/1//2011 storage system is needed to inject power into the KEA grid the moment wind production suddenly drops. By supplying necessary power through the energy storage system’s power converter, the grid frequency remains stable while a signal is sent to the Terror Lake hydropower generators to ramp up their hydropower output. As the wind energy storage system loses power after a relatively short period of time, the hydropower supplied by the Terror Lake facility will be there to balance the load, keep the grid stable, and supply reliable electricity. This micro‐scale energy bridge is a key component to KEA’s integrated wind‐hydro generation system under high wind penetration rates. The wind energy storage system will be either in one of two formats: either 1) a series of flywheels with power converters, or 2) a battery system with a power converter. Both system types provide the needed grid stabilizing function because they both work in the general manner as described above. KEA is currently modeling both systems with Electric Power Systems, Inc. to determine the best size of the system, and determine the most cost‐effective technology. This should be done this fall (2011) and the delivery time for the systems is about six months. The flywheel system has been used in wind systems around the world. Its primary advantage is the low maintenance requirements. KEA is currently examining the Powercorp Powerstore system, based in Australia. It consists of a 1.5 MW Piller (German) flywheel and an ABB Power Inverter. For KEA’s application in the Pillar Mountain High Penetration Wind Project, there would need to be a series of flywheels; our current engineering analysis is utilizing a series of three. Once the modeling is complete, the exact number of flywheels needed in series for KEA’s grid will be finalized. The Powercorp Powerstore systems have worked on other islanded wind‐diesel systems, as well as on islanded hydro‐ wind‐diesel systems. Information on the Powercorp Powerstore product is included in Exhibit E. The flywheels, though their control systems will be watching system frequency. Once frequency dips due to loss of wind power or other issues, the flywheel energy would be released onto the system through the power inverter to the level needed for the system. This reaction would occur within 4‐5 milliseconds, which is quick enough to mitigate any system frequency issues. At the same time, a signal would be sent to Terror Lake to raise load. The flywheels would then back off and Terror Lake would take over the system load. The flywheels are just a 30‐45 second bridge for Terror Lake to have time to react. As shown in the Exhibit E this has been successful in many locations. The other energy storage system KEA is examining is the XP battery system, which is used extensively in Hawaii for wind and solar ramping applications. It is a fast acting battery system that also goes through a power inverter. The main advantage to the battery system is that batteries are able to provide longer energy storage than a flywheel system. Information on the XP battery system is also included in Exhibit E. The system will work in the same manner as the flywheel system above. The optimum installed capacity for KEA’s system is 4.5 MW of additional wind. This amount of wind energy matches our grid needs, system stability needs, and load demand. The capacity factor for the Pillar Mountain High Penetration Wind Project turbines is estimated at 33%, which would supply an annual generation of approximately 13 million kilowatt‐hours. With the addition of an energy storage system, KEA would be able to increase the productivity of the original wind turbines as well by about 800,000 kilowatt‐hours per year. This increase in productivity from existing wind turbine units is a result of lessening the need to curtail wind energy production for grid stability since the energy storage system would be able to provide that necessary service. The anticipated barrier to full implementation of the Pillar Mountain High Penetration Wind Project is grid stability. The energy storage system in combination with Terror Lake’s hydropower need to keep grid frequency stable during wind fluctuations. If the energy storage system is sized too small, then KEA would need to curtail more wind production than planned while we engineer a solution to enlarge the size of the energy storage system. This potential barrier will be thoroughly modeled in depth before the purchase of the selected energy storage system. The other potential barrier would be if this new energy storage system were not be as plug‐and‐play as expected. There will likely need to be a significant amount of tuning on KEA’s entire grid system after the project components are installed to Renewable Energy Fund Grant Application Round 5 AEA12-001 Grant Application Page 15 of 27 7/1//2011 have everything working together properly. The existing 25 kilovolt power line that connects the existing wind turbines will be extended to the three new wind turbines and an additional transformer will be installed at High Substation in parallel to the existing transformer to handle the added capacity of the three new wind turbines. The energy storage system will also be installed at High Substation so that it can be transformed up to 12.47 kilovolts and connected to the KEA grid. 4.3.2 Land Ownership Identify potential land ownership issues, including whether site owners have agreed to the project or how you intend to approach land ownership and access issues. The area where the three wind turbines will be installed is owned by the State of Alaska. KEA is authorized to occupy state land on the Pillar Mountain ridgeline for the construction and operation of six wind turbines, three of which have already been installed. The Final Finding and Decision for Land Lease ADL 229859, which declares that DNR will issue a 30 year land lease pursuant to AS 38.05.810(e) to KEA, was issued in May 2010. A copy of the Final Finding and Decision for this state land lease is included in Exhibit G. KEA and DNR are currently involved with the survey and appraisal process to define the exact boundaries and value of the lease area in order to determine KEA's annual rent. (During this interim time while the survey and appraisal process is being determined, KEA has already been paying DNR an estimated annual rent.) DNR estimates that the survey and appraisal process can take a total of 3 to 5 years; therefore KEA will continue to operate under an Early Entry Authorization for the construction and operation of the Pillar Mountain High Penetration Wind Project. The current term on the EEA is through September 30, 2014. Land adjacent to the State land lease area, including the access road up the mountain ridge, is owned by the City of Kodiak. City Ordinance 1237 and Lease Agreement No. 133457 issued in 2008 authorizes KEA to conduct activities related to wind projects on Pillar Mountain. The energy storage system will be located within the High Substation Facilities on land owned by KEA. 4.3.3 Permits Provide the following information as it may relate to permitting and how you intend to address outstanding permit issues. • List of applicable permits • Anticipated permitting timeline • Identify and discussion of potential barriers There are no barriers to permitting approvals associated with installation and operation of the Pillar Mountain High Penetration Wind Project. KEA has been diligent in ensuring that the Pillar Mountain High Penetration Wind Project meets all federal, state, and local regulations. The following permit approvals have already been received: • Consistency Determination with the Alaska Coastal Management Program • Alaska Department of Natural Resource Land Lease ADL No. 229859 (See Exhibit G) • City of Kodiak Ordinance #1273 – An Ordinance of the Council of the City of Kodiak Authorizing the use of Pillar Mountain by the Kodiak Electric Association for support Activities Related to their Wind Generation Project Renewable Energy Fund Grant Application Round 5 AEA12-001 Grant Application Page 16 of 27 7/1//2011 • City of Kodiak Land Lease Agreement No. 133457 • Kodiak Island Borough Planning and Zoning Commission Conditional Use Permit • Kodiak Island Borough Zoning Compliance Permit • US Army Corps of Engineers Section 404 Clean Water Act Nationwide Permit 18 Application for the following three permits are currently being developed and will be acquired prior to construction of the Pillar Mountain High Penetration Wind Project. These permits were granted with the first three wind turbines and should not be a problem for the next three: • Federal Aviation Administration Determination of No Hazard to Air Navigation • Kodiak Island Borough Building Permit • Alaska Department of Environmental Conservation Section 402 Clean Water Act, 2011 Alaska Generation Construction Permit A summary table of permits and regulatory approvals, and a copy of the Final Finding and Decision for Alaska Department of Natural Resources Land Lease No. 229859 is included in Exhibit G. 4.3.4 Environmental Address whether the following environmental and land use issues apply, and if so how they will be addressed: • Threatened or Endangered species • Habitat issues • Wetlands and other protected areas • Archaeological and historical resources • Land development constraints • Telecommunications interference • Aviation considerations • Visual, aesthetics impacts • Identify and discuss other potential barriers There are no environmental or other land‐related barriers to the development of the Pillar Mountain High Penetration Wind Project. The wind turbine sites along the Pillar Mountain ridgeline have each been extensively studied to verify that this area is appropriate for wind energy development. The Alaska Department of Natural Resources, Division of Mining, Land and Water conducted an extensive review and public comment period as part of their Final Finding and Decision making process for Land Lease ADL 229859 (see Exhibit G). DNR concurred that this site is appropriate for wind energy development. The Alaska Coastal Management Program (ACMP) Final Consistency Determination also confirmed that the project complies with all the environmental guidelines set forth in the ACMP program. Even though Alaska no longer operates the ACMP, the extensive review involved with a consistency determination demonstrates that the Pillar Mountain High Penetration Wind Project is an environmentally‐sound project. Geo‐Marine, Inc. performed a critical issues analysis to address any potential environmental impacts resulting from wind energy development on Pillar Mountain, including an avian, vegetation, wetland and habitat Survey. An additional geotechnical investigation performed by Tetra Tech EC, Inc. verified the suitability of the mountain ridge top for supporting the foundations of the additional three wind turbines. Road access to the three new wind turbine sites will cross a small wetland area. KEA has already secured the appropriate permits with the US Army Corps of Engineers that authorizes the minor discharge into this small wetland area. KEA is currently examining the recently issued 2011 Alaska General Construction Permits and will develop a site‐specific Stormwater Pollution Prevention Plan as Renewable Energy Fund Grant Application Round 5 AEA12-001 Grant Application Page 17 of 27 7/1//2011 required. KEA conducted a year‐long Avian Use Survey in consultation with the Kodiak Chapter of the National Audubon Society and US Fish and Wildlife Service prior to the construction of the first three wind turbines on Pillar Mountain. The pre‐construction study results were distributed to the agencies in October 2007. Post‐construction use by bald eagles was also surveyed from July 2009 through the spring of 2010 to determine if there would be a difference between bald eagle use and flight behavior before and after the first three wind turbines were built. The results of this post‐construction survey confirmed that bald eagles were avoiding the wind turbines. This avian use research was presented at a national Wind Wildlife Research Meeting in October 2010. The best result though is the proven fact that there have not been any bird strikes for the two years of operation of the wind turbines. There are no historic, prehistoric or archeological resources known in the area where the wind turbines will be sited. If any cultural or paleontological resources are revealed during the course of construction, KEA will immediately contact the State Historic Preservation Office so that consultation per section 106 of the National Historic Preservation Act may proceed. A microwave radio path obstruction analysis was conducted by New Horizons Telecom to verify that the wind farm clears all communication paths. In reference to other telecommunication interference, the Federal Aviation Administration (FAA) has confirmed that the turbines clear their microwave path to the Kodiak Air Traffic Control Tower. KEA will be re‐applying for the FAA permits for the Pillar Mountain High Penetration Wind Project’s additional three turbines now that the construction schedule has been determined. The Kodiak community embraces the visual impact of the existing wind turbines on Pillar Mountain as an icon of their commitment to sustainability. When the Pillar Mountain Wind Project came online in July, 2009, KEA received the following comments regarding the wind turbines’ aesthetics: • I think it’s a great thing that Kodiak is going green! They look so awesome that I used Twitter to notify my friends about our wind turbines. Christine Morton, June 2009 • When you see a postcard from the City of Seattle, you see the Space Needle as part of that downtown area. I think the wind turbines on Pillar Mountain will be on postcards of Kodiak. I can see them from my office, from Deadman’s Curve, and from all over town. We’ll be happy when they are turning, making efficient, low cost, and clean energy. Craig Johnson, Edward Jones Investments, June 11, 2009 • The wind turbines look so “now” – I’m proud to be a KEA member. Mike Milligan, July 2009 • The wind mills are very aesthetic and thank you guys for trying to do the right thing by using renewable resources. Casey Cobban, July 2009 • Wind mills look pretty up there on Mt. Pillar. Dolores Mares, August 2009 Additional public comments are presented in Section 8. Renewable Energy Fund Grant Application Round 5 AEA12-001 Grant Application Page 18 of 27 7/1//2011 4.4 Proposed New System Costs and Projected Revenues (Total Estimated Costs and Projected Revenues) The level of cost information provided will vary according to the phase of funding requested and any previous work the applicant may have done on the project. Applicants must reference the source of their cost data. For example: Applicants Records or Analysis, Industry Standards, Consultant or Manufacturer’s estimates. 4.4.1 Project Development Cost Provide detailed project cost information based on your current knowledge and understanding of the project. Cost information should include the following: • Total anticipated project cost, and cost for this phase • Requested grant funding • Applicant matching funds – loans, capital contributions, in-kind • Identification of other funding sources • Projected capital cost of proposed renewable energy system • Projected development cost of proposed renewable energy system The full capital cost for the Pillar Mountain High Penetration Wind Project is estimated at $23,150,000. This grant application is for the construction costs of the project, estimated at $16,000,000. KEA is requesting $8,000,000 in grant funds with a KEA project match of $8,000,000. KEA does not anticipate any additional funding sources for this project. KEA is a not‐for‐profit rural electric cooperative and the KEA membership will fund all project costs not reimbursed in grant funds through their electric energy rates. KEA has obtained a new Clean Renewable Energy Bond (CREB) to finance all project costs not reimbursed in grant funds. No development costs have been proposed, all associated costs are considered capital costs. There is no new revenue source from this project. This project will enable the KEA membership to realize savings in their electric energy rates cost of power adjustment (COPA) due to a decrease in expensive diesel fuel consumption for electric energy generation. The following table provides the cost estimate for each of the milestones identified for the construction phase of the Pillar Mountain High Penetration Wind Project: CONSTRUCTION PHASE‐ PILLAR MOUNTAIN HIGH PENETRATION WIND PROJECT AMOUNT Milestone #1 Mobilization, installation, integration and commissioning of wind turbines $12,200,000 Milestone #2 Mobilization, installation, integration and commissioning of energy storage system $3,800,000 TOTAL $16,000,000 4.4.2 Project Operating and Maintenance Costs Include anticipated O&M costs for new facilities constructed and how these would be funded by the applicant. (Note: Operational costs are not eligible for grant funds however grantees are required to meet ongoing reporting requirements for the purpose of reporting impacts of projects on the communities they serve.) No operational costs have been included in this $8,000,000 grant request. Renewable Energy Fund Grant Application Round 5 AEA12-001 Grant Application Page 19 of 27 7/1//2011 KEA has been responsible for the operation and maintenance of the 2009 Pillar Mountain Wind Project and has two highly qualified wind technicians certified by GE to perform the monthly routine maintenance. KEA is in the process of training additional wind technicians to assist with the maintenance required to keep the three additional wind turbines in good operating condition. As KEA continues to utilize less diesel generation, available staff will be more heavily utilized in the renewable generation portfolio; therefore, no additional personnel are necessary. KEA will continue to contract with GE for 24/7 monitoring of the wind turbines and for on‐site engineering services, as well as support for the milestone maintenance required. Having continued support from GE allows the turbines to stay in optimal operational condition. KEA’s existing wind turbines are currently operating at about 98% availability. The AEA assumptions “Wind O&M Rural” are stated at 2.2 cents per kilowatt‐hour. KEA feels that calculation is accurate but not directly reflective of this project. As KEA will be able to divide costs between a total of six turbines instead of only the three turbines, our cost per kilowatt‐hour will be slightly lower than this assumption. Also, this project includes operation and maintenance (O&M) for the energy system storage devices; therefore KEA’s O&M calculations are slightly different than the AEA assumptions. KEA anticipates the annual O&M cost on the three new wind turbines will be $250,000, and the energy storage system will add an additional $50,000 in O&M expenses, for a total annual O&M cost of $300,000. Many of the O&M costs from this project will displace O&M cost on the diesel generation units. As depicted in the Net Present Value Table in Section 5, the Pillar Mountain High Penetration Wind Project’s O&M costs of $300,000 allows KEA to eliminate the higher diesel maintenance O&M costs of $586,500 in Year 1. KEA will continue to fund operation and maintenance through the electric energy sales revenue. No increase in electric energy rates will be necessary to fund O&M costs related to the Pillar Mountain High Penetration Wind Project. 4.4.3 Power Purchase/Sale The power purchase/sale information should include the following: • Identification of potential power buyer(s)/customer(s) • Potential power purchase/sales price - at a minimum indicate a price range • Proposed rate of return from grant-funded project KEA is the only electric utility in Kodiak and there will be no power purchase agreements. KEA is a generation, transmission and distribution not‐for‐profit rural electric cooperative. The power generated from the Pillar Mountain High Penetration Wind Project will go straight into the KEA grid. The project savings will also go straight to the members of the cooperative. The community will experience a lower cost of power from decreased diesel fuel consumption. The rate of return on this project is not an appropriate gauge for the overall benefit to the membership; however, it should be noted that the avoided fuel costs, made possible by the project, is expected to provide the KEA membership with net savings within the first year of operation. 4.4.4 Project Cost Worksheet Complete the cost worksheet form which provides summary information that will be considered in evaluating the project. The Pillar Mountain High Penetration Wind Project Cost Worksheet form is found at the end of this grant application on pages 28 ‐ 34. Renewable Energy Fund Grant Application Round 5 AEA12-001 Grant Application Page 20 of 27 7/1//2011 The numbers utilized in the enclosed cost worksheets are based on 2010 actual data where applicable. The cost of fuel utilized in the cost worksheet is based on KEA’s July 2011 actual price. The Demand Load Forecast information is calculated using regression analysis based on 10 years of actual demand to predict the values for the next ten years. As indicated in the graph below, KEA’s total sales have risen over the past ten years. If sales continue to grow as predicted over the next ten years, KEA will be challenged to accomplish their vision “Endeavor to produce 95% of energy sales with cost effective renewable power solutions by the year 2020” with our existing generation infrastructure. The total savings, cost to benefit calculations, as well as the net present value calculations for the project are based on receiving $8,000,000 in grant funds. The simple payback calculation on this project is just over 3 years. This calculation is based on the total project cost savings divided by the total capital cost of $23,150,000. Additional detail on the economic analysis is provided in Section 5 below. SECTION 5– PROJECT BENEFIT Explain the economic and public benefits of your project. Include direct cost savings, and how the people of Alaska will benefit from the project. The benefits information should include the following: • Potential annual fuel displacement (gal and $) over the lifetime of the evaluated renewable energy project • Anticipated annual revenue (based on i.e. a Proposed Power Purchase Agreement price, RCA tariff, or cost based rate) • Potential additional annual incentives (i.e. tax credits) • Potential additional annual revenue streams (i.e. green tag sales or other renewable energy subsidies or programs that might be available) • Discuss the non-economic public benefits to Alaskans over the lifetime of the project The Pillar Mountain High Penetration Wind Project optimizes fuel‐free renewable technology to lower and stabilize the cost of power for KEA’s cooperative members. The economic and public benefits and project savings of this project for the people of Alaska are enormous, as detailed in the two tables below that present the information used for calculating the total project savings.

Based on the current US Treasury Bond Rate and information provided by our lender, it is anticipated KEA’s CREB Loan will be based on a 17 year maturity at 1.27% interest. The industry standard for wind turbine life is 20 years; therefore, the project life is anticipated to be 20 years as indicated above. KEA has estimated the annual operation and maintenance (O&M) costs to be $250,000 on the wind turbines, and $50,000 on the system stability system, for a total annual cost of $300,000. These O&M costs have been inflated at 3% in the Net Present Value Table. The fuel savings calculation is based on 13.8 million kilowatt‐hours in wind energy production that displaces the need for diesel‐powered generation. To calculate the fuel savings, an efficiency rate of 14.4 kilowatt‐hours per gallon was utilized. Therefore, 13.8 million kilowatt‐hours generated by a diesel engine with an efficiency of 14.4 kilowatt‐hours per gallon would require 958,333 gallons of diesel fuel. At KEA’s current price for a gallon of diesel fuel at $3.32 per gallon, the fuel savings avoided by the wind energy production comes to $3,181,666. For the fuel savings calculation, fuel costs are inflated by 3% for the 20‐year life of this project. The savings calculation for diesel engine maintenance reduction is based on actual O&M costs associated with operating KEA’s diesel units. The total combined cost to utilize diesel generation rather than wind energy from this project, taking both O&M and the current fuel cost of $3.32 per gallon into account, is 27.30 cents per kilowatt‐hour in the first year. Taking $8 million in AEA grant funds into consideration, the Pillar Mountain High Penetration Wind Project costs calculates out to 9 cents per kilowatt‐hour in the first year. The majority of the costs for the project construction are based on fixed costs (i.e., interest and depreciation); therefore, the savings per kilowatt‐hour becomes much greater in future years as fuel costs continue to escalate. The inflation rate of 3% used in KEA’s analysis is very conservative compared to the actual fuel cost increases experienced over the past 10 years. It is very likely that the cost savings of this project would actually be much greater than projected. The following graph provides the cost per kilowatt‐hour for the 20‐year life of the project as compared to the cost to operate diesel‐based generation over this same time frame. The savings projections for our community exceed 20¢ per kilowatt‐hour by Year 4, and reaches close to a 40¢ per kilowatt‐hour savings by Year 20. Renewable Energy Fund Grant Application Round 5 AEA12-001 Grant Application Page 23 of 27 7/1//2011 As shown in the graph above, shifting Kodiak’s source of electric energy from diesel to fuel‐free stabilizes the cost of power. Providing reliable power at a predictable cost is a benefit KEA strives to provide for future economic development. Expanding KEA’s renewable energy portfolio through the Pillar Mountain High Penetration Wind Project provides an extra benefit to Alaska’s economy through new marketing opportunities for businesses using KEA’s renewably‐based electricity to manufacture their products. KEA’s renewable energy has become a value‐added marketing campaign for Alaska’s seafood industry, as demonstrated by the “Salmon Wind Water” branding of Kodiak’s wild salmon, and new wind decals on Pacific Seafoods’ product packaging (example provided in Exhibit A). In terms of technological development, KEA will continue to share the lessons learned from our research and implementation of wind energy development for the benefit of the Alaska public. The innovative system stability solutions developed for the Pillar Mountain High Penetration Wind Project will serve as a working model for other Alaskan communities looking to integrate large amounts of variable renewable energy onto their isolated electrical grid systems. SECTION 6– SUSTAINABILITY Discuss your plan for operating the completed project so that it will be sustainable. Include at a minimum: • Proposed business structure(s) and concepts that may be considered. • How you propose to finance the maintenance and operations for the life of the project • Identification of operational issues that could arise. • A description of operational costs including on-going support for any back-up or existing systems that may be require to continue operation • Commitment to reporting the savings and benefits KEA’s plan to operate the Pillar Mountain High Penetration Wind Project will follow the model developed for the 2009 Pillar Mountain Wind Project. The excellent wind resource atop Pillar Mountain coupled with the proven reliability of the GE wind turbines and continued proper upkeep of the units, will provide a continual source of renewable wind energy to the Kodiak community to further mitigate the use of diesel fuel for many years into the future. KEA’s business structure will change slightly by allocating resources from diesel fired generation operation focus to the renewable portfolio generation assets. The only potential operation issue that is foreseen is related to deployment of the new energy storage system on KEA’s unique grid configuration. The risk associated to the energy storage system will be remedied by curtailing the wind energy production from the wind turbines until a viable solution is implemented. KEA anticipates the O&M cost on the three new wind turbines will be $250,000 and the energy storage system will add an additional $50,000 to O&M expenses annually for a total of $300,000. Many of the O&M costs from this project will displace the more costly O&M associated with the diesel generation units. This project is sustainable on a continual basis for the following reasons: • KEA has been responsible for the successful operation and maintenance of the Pillar Mountain Wind Project since July 2009 when the initial turbines were commissioned. • KEA personnel have knowledge and experience in wind turbine maintenance with two of KEA’s three wind technicians holding GE certification. • The GE 1.5 MW wind turbine is the industry standard of North American and one of the most used turbines in the world. Renewable Energy Fund Grant Application Round 5 AEA12-001 Grant Application Page 24 of 27 7/1//2011 • GE will continue to monitor the Pillar Mountain wind park 24/7 through a SCADA system. • The energy storage systems KEA is examining are tried and tested systems for quick release energy storage. • KEA has diligently improved its grid infrastructure to successfully implement the integrated wind‐hydro generation system to achieve its renewable energy vision, of which this High Penetration Wind Project is the next necessary step. KEA will continue to share lessons learned by this project with AEA and other communities throughout Alaska and the world to help move toward greater energy independence. SECTION 7 – READINESS & COMPLIANCE WITH OTHER GRANTS Discuss what you have done to prepare for this award and how quickly you intend to proceed with work once your grant is approved. Tell us what you may have already accomplished on the project to date and identify other grants that may have been previously awarded for this project and the degree you have been able to meet the requirements of previous grants. Given its huge public benefit, KEA is aggressively moving forward with Pillar Mountain High Penetration Wind Project. The grant funds associated with this application will move us through the construction phase and into its final acceptance and commissioning. The Pillar Mountain High Penetration Wind Project is a new renewable energy development project that has not been proposed in previous AEA Renewable Energy Fund grant rounds. When the grant for this project is awarded KEA will be moving into the construction phase (July 2012). KEA is moving forward with this project and has expended funds on site preparation and surveying. KEA is very appreciative of support received from AEA for other renewable energy developments, including the initial wind turbine installation on Pillar Mountain in 2009, and the installation of a third turbine‐generator at the Terror Lake Hydroelectric Project. KEA has been in full compliance with these previous grant agreements. The information below provides detail on a “grid stability” assessment grant provided by AEA for $100,000. This grant could be viewed as related to this project. • Round I ‐ Pillar Mountain Wind – Phase II Assessment ‐ $100,000 Grant # 2195460 This award from AEA helps fund a feasibility study to determine the most cost effective manner to maintain grid stability during the fluctuations from wind power. This study assisted KEA with the in‐depth look at our system’s reliability issues surrounding high penetration wind generation on an isolated grid. As of June 2011, KEA has expended $137,218.21 on this project. It is anticipated this grant will be finalized with the next quarterly report in October 2011. SECTION 8– LOCAL SUPORT Discuss what local support or possible opposition there may be regarding your project. Include letters of support from the community that would benefit from this project. It is KEA's responsibility to supply reliable and affordable electricity to a community who prides itself on living in harmony with its surrounding nature. The Kodiak community is extremely supportive of KEA’s efforts in developing more wind energy production. During the planning, construction and operation of the 2009 Pillar Mountain Wind Project, KEA has received the following comments: Renewable Energy Fund Grant Application Round 5 AEA12-001 Grant Application Page 25 of 27 7/1//2011 • Keep up the good work on making Kodiak a better place to live.

This is the first time my bill has been under $100 since I can’t remember! Praise the water and wind power. Leslie G. Seaton, June 2010 KEA is viewed as a shining star in implementing sustainable, renewable energy solutions and has been recognized for its performance by the US Department of Energy and National Rural Electric Cooperative Association as the 2009 Wind Cooperative of the Year for leadership, innovation, commitment, project creativity and benefits resulting from Alaska’s first utility‐scale wind project. KEA was also awarded with the 2009 Kodiak Chamber of Commerce Cornerstone Award for developing Kodiak’s renewable energy resources for the betterment of all Kodiak residents. The continued support provided by the local community of Kodiak and the statewide community of Alaska has been a major component to KEA’s success. Renewable Energy Fund Grant Application Round 5 AEA12-001 Grant Application Page 26 of 27 7/1//2011 KEA’s efforts with expanding its renewable wind‐hydro energy generation system continue to draw the attention of media outlets that travel to Kodiak to learn how even a small rural electric cooperative like KEA could make a huge difference in our nation’s efforts to develop its renewable energy resources. As support of renewable energy within the community continues to grow, a renewed sense of pride has emerged for Kodiak’s progress in sustainable living. The Pillar Mountain High Wind Penetration Project allows KEA to continue developing sustainable sources of renewable energy for generations to come. Exhibit A includes additional letters of support for the Pillar Mountain High Penetration Wind Project.

The level of information detail varies according to phase requirements. 1. Renewable Energy Source The Applicant should demonstrate that the renewable energy resource is available on a sustainable basis. The Pillar Mountain High Penetration Wind Project proposes to install three (3) additional GE 1.5 MW wind turbines along with a wind energy storage system that would integrate the high level of wind energy into Kodiak Electric Association, Inc.’s (KEA’s) isolated electric grid. This project will provide additional renewable wind generation to Kodiak and significantly decrease the community’s dependence on diesel fuel. Utilizing historical information from the 2009 wind installation on Pillar Mountain, this project is estimated to have 98% availability and a 33% capacity factor. The excellent wind resource atop Pillar Mountain coupled with the proven reliability of the GE wind turbines and continued proper upkeep of the units, will provide a continual source of renewable wind energy to the Kodiak community to further mitigate the use of diesel fuel for many years into the future. Other influences on the sustainability of this project include: • KEA has been responsible for the successful operation and maintenance of the Pillar Mountain Wind Project since July 2009 when the initial turbines were commissioned. • KEA personnel have knowledge and experience in wind turbine maintenance with two of KEA’s three wind technicians holding GE certification. • The GE 1.5 MW wind turbine is the industry standard of North American and one of the most used turbines in the world. • GE will continue to monitor the Pillar Mountain wind park 24/7 through a SCADA system. • The energy storage systems KEA is examining are tried and tested systems for quick release energy storage. • KEA has diligently improved its grid infrastructure to successfully implement the integrated wind‐hydro generation system to achieve its renewable energy vision, of which this High Penetration Wind Project is the next necessary step. Annual average resource availability. 98% turbine availability ‐ (33% wind capacity factor) Unit depends on project type (e.g. windspeed, hydropower output, biomasss fuel) 2. Existing Energy Generation and Usage KEA operates an isolated electrical grid system and is not connected to any other gird or utility. The Terror Lake Hydroelectric Facility is KEA’s primary generation source, and it controls KEA’s system frequency. KEA brought 4.5 MW of wind online in July of 2009 with the completion of the Pillar Mountain Wind Project. The wind turbines work in concert with the Terror Lake Hydro facility as an integrated wind‐hydro generation system. KEA also operates and maintains four independent diesel generation facilities (Kodiak Generating Station, Nyman Power Plant, Swampy Acres Plant and Port Lions) which are a mixture of diesel reciprocating engines and diesel‐fired combined cycle generation units. Renewable Energy Fund Round 5 Project Cost/Benefit Worksheet RFA AEA12-001 Application Cost Worksheet Page 29 7-1-11 KEA’s generation system is centered on supporting Terror Lake as the primary generation source. There is a large amount of backup diesel‐powered generation installed on the isolated system in case the hydro facility is unavailable. Diesel reciprocating engines cover peak loads and provide storm system protection and a combined‐cycle plant is used for longer periods for lake level augmentation. The table below details KEA’s generation resources. The capacity numbers used are high end nominal for the machines. This is a point where the machines can be operated on a high end for a period of time, but does not reflect total potential due to the detrimental effects of full load operations on diesel engines. Note that the efficiencies are for the load points mentioned at ideal conditions.

The 2009 Pillar Mountain wind project is currently generating approximately 12,200,000 kWh annually, despite the turbines’ ability to generate 13,000,000 kWh, because they are curtailed for system frequency limitations. The High Penetration Wind Project’s three new 1.5 MW wind turbines are estimated to generate an un‐curtailed 13,000,000 kWh, and allow the additional 800,000 kWh from the 2009 wind turbines without curtailment. This brings the total energy generation expected from all six turbines on Pillar Mountain to 26,000,000 kWh annually.

Project Cost a) Total capital cost of new system $23,150,000 The AEA Assumptions for “Wind Installed Cost Rural” are $5,000 x 4,500 kW = $22.5 Million. Much of the infrastructure required for this project was already completed with the 2009 Pillar Mountain project; therefore, we anticipate slightly lower costs than the AEA Assumptions for the actual wind installation. However, this project also includes additional costs for the associated energy storage system that will be utilized to integrate the high wind penetration onto our isolated grid. b) Development cost Development costs have been included in the total capital costs. c) Annual O&M cost of new system $300,000 The AEA Assumptions “Wind O&M Rural” are 2.2 cents x 13.8 Million = $303,600. KEA anticipates our wind costs will be slightly lower than the AEA Assumptions as we will be able to split some of the costs between all six of KEA’s wind turbines, and no additional personnel will be necessary. We anticipate O&M costs on the new wind turbines at $250,000, plus an additional $50,000 for the O&M for the energy storage system. d) Annual fuel cost N/A 5.

The more fuel displaced with renewable energy, the greater the savings. Reducing dependence on diesel fuel also minimizes the impact of volatile fuel prices so that KEA can move toward more stable electric energy rates. Energy cost stability allows local businesses to look toward future business development, thereby providing Renewable Energy Fund Round 5 Project Cost/Benefit Worksheet RFA AEA12-001 Application Cost Worksheet Page 33 7-1-11 an economic boost to the Kodiak community through increased production and employment. With increased wind energy production provided by the High Penetration Wind Project, KEA will be able to continue assisting the USCG Base Kodiak with meeting their federal renewable energy mandates with Renewable Energy Credit (REC) allocations, while partnering with more local businesses interested in receiving REC allocations for value‐added economic benefit to their companies. d) Alaska public benefits $85,492,575 In terms of direct monetary benefit, Alaska’s Public Benefit includes eliminating the need for 958,333 gallons of diesel fuel to be consumed annually for power generation. To quantify this monetary benefit to Alaskans, consider the 20‐year savings of not consuming 958,333 gallons of $3.32 per gallon fuel: $63,633,311 in savings if fuel costs remained at this price for 20 years; or $85,492,575 with a 3% inflation rate applied. In terms of technological development for Alaska’s energy sector, KEA’s 2009 Pillar Mountain Wind Project provided a model for industry‐scale wind parks, which is helping to move other Alaska communities toward self‐ reliance through reduced dependence on fossil fuels. With the High Penetration Wind Project, the Alaska public will continue to benefit from KEA’s research and implementation of system stability solutions for integrating variable renewable energy onto isolated electrical grid systems. 6.

Version 20071108 Page 1 www.pcorp.com.au PowerStore Product Specification Product Description and Data Sheet The PowerStore is a compact, versatile and robust electrical energy storage device. Its main purpose is to stabilise power systems to increase renewable energy penetration and quality of supply. This document contains the Product Description, explaining the main PowerStore components and control functions, as well as Data Sheets for each model. PowerStore combines an 18 MW-second low-speed flywheel with two solid state IGBT based inverters to provide a compact, robust, reliable and high-performance grid stabilising device. PowerStore is able to sink or source energy up to its nominal power rating. PowerStore is also capable of responding to power system changes, with a response time of approximately 5 ms. MG 400 V ac 50 Hz 700 Vdc Variable Frequency AC Flywheel-Grid Interface Flywheel Drive Figure 1 - PowerStore Single Line Diagram The PowerStore consists of the following four main components: · Container Building · Flywheel Spinning Mass · AC-DC-AC Converter System · Control and SCADA System CONTAINER BUILDING All of the components are conveniently factory installed into a 40 foot shipping container, requiring a minimum of installation on-site. Air conditioning is installed at one end of the container provide cooling for the flywheel and converter system. Figure 2 - Flywheel Installed within the containerised building Figure 2 displays the arrangement of the main PowerStore components. On the left can be seen the flywheel with the air- conditioning system mounted behind. On the right are the Control System and Converter System switchboards. . Figure 3 - PowerStore 500kW Container Outside view Figure 3 shows the PowerStore container building of a PowerStore 500 from the outside. The purpose built container has a roof for sun and rain protection. The personal access door is open in the above picture. Figure 4 - Control Cabinet with SCADA Screen, inside of container Figure 4 shows one person working on the SCADA Screen and the second person behind on the flywheel. Two three phase power feeds (one for the main power attachment, the other for auxiliary components including the cooling system) and some basic control wiring are all that is required for electrical connections. As a result the installation on site can be completed within days. The isolation of the system can be undertaken through lockable isolators separating the PowerStore from the mains supply. Version 20070622 Page 2 www.pcorp.com.au PowerStore Product Specification Flywheel Spinning Mass The selection of flywheel has been made considering reliability in service. The machine manufactured by Piller in Germany has been on the market for approximately 7 years and there are in excess of 700 units installed in UPS applications operating 24 hours a day 7 days a week around the world. This unit rotates at a rated speed of 3,600 RPM and uses a pressurised helium environment to reduce frictional losses. The unit has a lifting magnet that holds the weight of the 3,000 kg flywheel during operation, ensuring a long life, reduced losses and low maintenance. Power for the lifting magnet is derived from the generator mounted on the flywheel shaft, allowing the lifting magnet to be fully functional whenever the flywheel is spinning at operational speed – even if supply power is removed from the machine. Oversized primary mechanical bearings are also included to hold the weight of the flywheel while it is stationary and below operational speed. In the event of a primary bearings and lifting magnet failure, catch bearings are installed to carry the weight of the flywheel while it is stopping, providing a fail-safe system. Figure 5 - Flywheel The flywheel requires a preventative service inspection once per year. The unit has an automatic greaser installed which needs to be refilled every 5 years. Helium is provided form a source bottle that requires replacing typically after three years. There are no other items that require regular maintenance. AC-DC-AC Converter System Custom control software has been developed in Australia, to create a high performance IGBT based Flywheel Grid Interface as well as Flywheel Drive. The hardware is based on standard power conversion modules used for Variable Speed Drives and other Power Quality Products. Using these proven modules results in a highly reliable design through an installed base of thousands of units worldwide. The use of two IGBT inverters, connected via a DC bus allows the flywheel to rotate at a speed that is independent of: · Grid frequency · Grid voltage · Power export/import This also allows the PowerStore to export and import at maximum power ratings regardless of the energy stored, from 0% to 100% capacity. There is no need to de-rate the PowerStore at lower energy levels. Figure 6 - IGBT Inverter Module used for PowerStore The Flywheel Grid Interface inverter is also capable of delivering power during brown-out events by increasing the output current until the current limit of the inverter is reached. The DC Bus can also be fitted with a dump load to prevent the flywheel from “over-filling”. This is most useful in renewable energy systems where the available energy to discharge determines how efficiently the hybrid system can be operated. Control and SCADA System PowerStore has been designed for remote unsupervised operation. Apart from the yearly service inspection of the equipment there is no need to attend the system. An advanced SCADA and Control System monitors and controls the flywheel and converter components to achieve safe and reliable operation, provide data recording and remote access. Data recording is provided at two levels, a high resolution (down to 100 ms) recording system for fault finding and a low resolution (10 minute) recording system for performance and financial analysis. Figure 7 - PowerStore Wind Diesel SCADA Screen Version 20070622 Page 3 www.pcorp.com.au PowerStore Product Specification A number of variables are recorded in the SCADA system such as PowerStore Power PowerStore Energy Level Mains 3-phase Voltage Mains 3-phase Currents Flywheel, Container and Inverter Temperatures Alarms, Status and Operation Mode Next PowerStore Service time In addition, this data can be exported into a wide range of software, include Microsoft Excel for further analysis. Figure 8 - PowerStore Data Recording Trending Screen The PowerStore can be remotely started and stopped and alarms remotely monitored. These can also be remotely reset. The control cabinet houses a local interface for control, as well as a local touch screen for status information and diagnosis (see Figure 4 - Control Cabinet with SCADA Screen, inside of container). All of the information available locally is also available remotely, across data links including Ethernet (wired or wireless) and PSTN/PABX. Typical Applications PowerStore can be integrated and controlled in a number of different ways. Frequency and Voltage Support In an isolated system frequency can change rapidly with changes in the output. An example is with a renewable energy generator or a swinging load. PowerStore can be used to smooth out changes in frequency by calculating the average system frequency and then using a dead band around this average frequency to determine when it generates or consumes active power. If the actual system frequency is within the dead band, PowerStore frequency support function is inactive. If the actual system frequency falls outside of the dead band, PowerStore will respond by charging or discharging to limit the frequency deviation. Changes to the average system frequency are allowed to occur to accommodate for operations in droop mode or due to the presence of a time correction system. The PowerStore also supports system voltage. It uses the average system voltage in combination with a dead band, similar to the frequency support control algorithm. If the actual system voltage is outside the dead band the PowerStore generates reactive power to limit the amount of voltage deviation. Parameters for the dead band and associated control algorithm are adjustable during commissioning. All measurements of system voltage and frequency are taken at the PowerStore’s low voltage connection point. Alternatively a high voltage connection point can be used as well. Through the above voltage and frequency support the PowerStore is able to work like a “noise filter” to suppress voltage and frequency fluctuations in the power system. PowerStore is capable of supporting frequency or voltage until it has reached its total nominal kVA power limit or exhausts stored energy. It ramps its power flow down to near zero if it approaches the fully charged or empty state. PowerStore Charge Control The charge level at which the PowerStore normally operates can be set between full and empty during commissioning. The normal charge level is set to ensure there is sufficient energy to carry out the frequency support for smoothing the power system load fluctuations plus a margin to cover the loss of generation plant such as a diesel generator. The recharging or discharging back to the idle energy level is controlled by a maximum power level that the PowerStore will consume or generate. Maximum power level can be set as a fixed parameter for charging or discharging or adjusted dynamically by an external power system management system during operation (e.g. the external power management system may only want to recharge if renewable power is available). Step Load Response The PowerStore has a very fast response time both for charging as well as discharging. In case of loss of plant within a power system (e.g. a generator has tripped offline) usually a step in the system load appears which results in a large frequency deviation. Such changes can cause load shedding of consumer feeders. PowerStore is capable of compensating for this step load by discharging up to its nominal power rating within milliseconds. After PowerStore has picked up the load and discharges its energy into the power system it gradually reduces its power output to pass the load back to the power system. In this event the PowerStore acts like a “shock absorber” to dampen the step load impact on the system’s frequency and voltage. In the above case a power management system coordinating the schedule of generation plant needs to call replacement capacity to ensure the PowerStore can pass the additional load back to the generators. For this purpose the PowerStore provides a process interface that allows other controllers to monitor its status. PowerStore working like an electrical “noise filter” to smooth power fluctuations, plus the ability to minimise the impact from loss of plant through the “shock absorber”, makes PowerStore ideal for managing the starting of large loads or supporting system stability after a re-closing event. Spinning Reserve Reduction Isolated power systems require the provision of spinning reserve to allow for the sudden increase in load or the sudden loss of generation plant. Spinning reserve is usually provided by the conventional generators such as diesel or gas fuelled reciprocating engines. As a result generators are not operated at their rated power output where the fuel efficiency is usually the highest. PowerStore is able to provide spinning reserve in the power system and allow the operation of the generation plant closer to its rated power output. It even allows the system load to exceed the generation capacity online for a short amount of time, delaying engine start if load changes are only of short duration. Through the measurement of power output of each generator the PowerStore “load shares” the peak power of the generators and provides its share when the generators are exceeding their rated power. In case the charge level of the PowerStore falls below a set parameter, the supervising power management system schedules another generation plant online. Version 20070622 Page 4 www.pcorp.com.au PowerStore Product Specification Figure 9 - Diesel Power Station Graciosa Island, Acores Fault Ride Through PowerStore is able to ride through faults, providing grid stability in case of a loss of a generator or large system disturbance. The PowerStore is capable of providing real and reactive power to support the system When the system voltage is depressed During a fast rate of system frequency change During an instantaneous voltage phase shift The above events usually occur during line faults within the distribution system. PowerStore has been designed to ride through those distribution faults, provide system stability and support the system recovery after the fault has been cleared. Figure 10 - PowerStore actual Fault Ride Through event recorded Backup Power Supply In the event of a mains failure (black station) the flywheel will slowly spin down until standstill. While it is spinning down it provides power to keep the Control and SCADA system alive to monitor the controlled shutdown process. No external UPS backup is required. Protection The PowerStore has a number of protection systems in place including but not limited to: Mains Over Voltage Flywheel and Converter Over Temperature Flywheel Over Speed Converter Over Current The PowerStore automatically de-rates itself in case the converter system detects a temperature overload.

Darwin based company, Powercorp Pty Ltd, has designed a ‘Wind/Diesel/Hydro/PowerStore system’ that is the first of its kind in the world! Powercorp’s Marketing Manager Will Galton said, "Powercorp’s primary role in the Azores Wind/Diesel/Hydro project was to upgrade the current power station with the newly developed flywheel energy storage system, PowerStore. The installation of Powercorp’s new technology will enable the local utility Electricidade dos Acores to maximise the wind penetration into the Power Station on the island. It is an exciting time for all involved as this project had been in the planning for some time." Page 1 of 3Powercorp :: PowerStore Flores 8/10/2011http://www.pcorp.com.au/index2.php?option=com_content&task=view&id=53&Itemid=133&p... Electricidade dos Acores is an innovative energy provider to the Azores archipelago located in the middle of the North Atlantic Ocean, roughly 1500km west from Lisbon. There are nine Azorean Islands that EDA provide energy to with their environmental friendly wind/diesel/hydro power stations. With the addition of Powercorp’s new technology, EDA is demonstrating their commitment to renewable power generation. Powercorp is working with the local power quality engineering company QEnergia to assist with the project logistics. QEnergia are responsible for the installation and local content of the Flores Island project. PowerStore is a flywheel based energy storage system that has been specifically designed to provide peak lopping and spinning reserve and overcome transient and cyclic loads on grid connected or isolated systems. Page 2 of 3Powercorp :: PowerStore Flores 8/10/2011http://www.pcorp.com.au/index2.php?option=com_content&task=view&id=53&Itemid=133&p... Close Window The PowerStore connected to the Flores power system operates fully automatic aside the manual controlled power stations. At the second installation in the neighbouring island Graciosa, Powercorp will also provide a newly developed control system that integrates the renewable energy with diesel generation and PowerStore so that excess renewable energy is not wasted. This PowerStore Integration Package automatically controls and monitors all diesel generator sets, wind turbines and PowerStore. It also allows the diesel generator and wind turbines to be operated automatically without human intervention. The two Enercon E-30 wind turbines currently operate as negative load to offset diesel fuel. There are inherent problems that occur with these sorts of configurations. Wind speed frequently goes through gusts and lulls, and if this natural fluctuating wind speed isn’t managed sufficiently it can result in wasted renewable energy, a lack of operational efficiency and poor power quality leading to supply outages. The technologies in PowerStore control can overcome these inherent problems. Since the commission of PowerStore in October, fewer diesel generators have been required during periods of high wind excess resulting in the reduction of Green House gas emissions and diesel cost savings. Compared to conventional Wind/Diesel/Hydro installations the excess renewable energy is not being wasted, making Powercorp’s technology superior.

Some of our selected project experience is below: EnvironmEntal Due Diligence At Tetra Tech, we take pride in knowing what qualifies as a good opportunity. We help our clients who are considering investing in wind projects, portfolios, or companies to assess the environmental, engineering, and constructability strengths and weaknesses of a proposed project to support acquisition decisions. Preliminary Siting A professionally completed review supports clients in assigning a fair evaluation on wind prospects. As part of our due diligence report, we can assist with the evaluation of potential project locations by creating maps; preparing/reviewing the development process checklist, schedule, and budget; and performing preliminary environmental, engineering, transmission, and constructability screenings. Critical issues analysis Successful siting and permitting of wind energy facilities relies on the ability to address critical issues as early as possible in the development process. As an industry leader in critical issues analysis (CIA), Tetra Tech has conducted hundreds of CIAs for wind projects throughout North America, examining issues involving biological resources (e.g., birds and bats), cultural and historic resources, visual impacts, land use compatibility, geotechnical suitability, aviation routes, communications pathways, noise, transmission, and other constraints. Early and thorough evaluation of site conditions saves time and money, and helps developers to communicate site value to investors, potential buyers, and utilities issuing Power Purchase Agreements. Tetra Tech’s process is modular, allowing us to look at any number of key resource areas simultaneously. Geographic information Systems (GiS) application and Data management Our GIS services enable us to respond faster and with better results within the tight timelines required to evaluate and secure potential sites. Tetra Tech employs GIS technology to help our clients rapidly identify, acquire, and permit prospective sites for wind energy development. GIS mapping and decision-making tools allow us to perform critical issues analyses, field data collection support, constraint mapping, facility design support (including general GIS and Computer- Aided Drafting and Design (CADD) services), permitting and decision support (including complex spatial analyses), spatial data management, project portfolio development in conjunction with graphic design services, and Web mapping (including ArcGIS Server/Google Earth mashups). Constraint mapping Constraint mapping provides a picture of opportunities and challenges pertaining to the siting of turbines and various ancillary facilities, from roads to substations. Our constraint mapping service is made possible through the use of readily available GIS data and field survey results. Constraint mapping is a crucial step in critical issues analysis, resulting in a realistic conceptual layout that can support permitting and cost-effective construction. Biological resource Studies One of the biggest challenges facing the wind energy industry is the potential for the construction and operation of generating facilities to negatively affect wildlife and wildlife habitat, protected vegetation, and rivers, streams, wetlands, or other valued aquatic resources. It is often a challenge for developers to understand what studies are needed and when the studies need to begin to keep the project on schedule. Tetra Tech’s focus is on the identification of potential biological concerns early in the development process so effective siting, avoidance, minimization, and mitigation strategies can be implemented. Renewable eneRgy ▪ windDevelopment Services The critical issues analysis represents not more than 5 percent of the overall cost of permitting, and most aspects of inquiry can usually be accomplished in less than 30 working days. "Tetra Tech was integral in the success of the environmental permit acquisition process for the Disraeli Bridges Project. Not only were there tight timelines, legislative changes significantly increased the environmental scope on the project. The EIS was well received, by both the provincial and federal reviewers for completeness and content. The EIS was structured to suit the needs of each authority. Upon submission of the EIS, Tetra Tech was in constant contact with the authorities ensuring the permitting process for the project did not encounter unexpected challenges and guiding the project permitting through the necessary approvals. Tetra Tech was diligent with ongoing updates and follow up with each of the authority which assisted the clients in risk management as wells as making sure each authorities realized the significance of a timely permit process. Tetra Tech continues to provide ongoing assistance and follow up on the environmental scope for the project as we move into the execution phase." Client Quote - Disraeli Bridges Project Tetra Tech is at the forefront of developing and implementing focused information reviews and field protocols for wildlife surveys, with an emphasis on birds and bats as well as provincial, state, and federally listed species. Our biological staff members are experts in all aspects of natural resources, having worked on more than 450 wind projects in North America. We have excellent relationships with provincial, territorial, state, and federal agencies. Tetra Tech biologists have worked and lived in a wide range of habitat types and climates, from tropical locations in Latin America to the Arctic Region in North America. In addition to their broad field experience and extensive local and regional expertise, our team of biologists has developed analytical models (e.g., habitat models, population models) that have proven to be powerful tools for predicting potential wildlife impacts from wind energy development. In addition, Tetra Tech has designed and performed post-construction monitoring programs, including mortality monitoring and behavioral studies. Development Services Tetra Tech directs and facilitates consultation under federal legislation for the United States (e.g., National Environmental Policy Act, Endangered Species Act, Bald and Golden Eagle Protection Act, Migratory Bird Treaty Act) and Canada (e.g., Canada Environmental Assessment Act, Fisheries Act, Species at Risk Act, Wildlife Act, Migratory Birds Convention Act). As part of these consultation efforts, Tetra Tech has prepared Environmental Impact Statements, Environmental Assessments, Biological Assessments, Fish Habitat Compensation Plans, Avian and Bat Protection Plans, Eagle Risk Assessments, and Habitat Conservation Plans. We track provincial and federal regulatory changes and guidelines, so we are always in a position to provide the necessary services and keep our clients informed. In addition to our successful interactions with regulators, Tetra Tech’s biological experts present technical and scientific papers at American Wind Energy Association, Canadian Wind Energy Association, and National Wind Coordinating Collaborative (NWCC) sponsored meetings and technical workshops, as well as research results at scientific meetings. We also provide expert contributions to industry initiatives (e.g., development of whooping crane conservation strategy), NGO (non-government organizations) initiatives (e.g., NWCC Wildlife Work Group and its subcommittees on Grassland-Shrub Steppe Birds for prairie chickens and greater sage-grouse), and regulator initiatives (e.g., development of analytical tools for golden eagle risk assessment). Tetra Tech avian and bat biologists are at the forefront of technological innovation for conducting studies to support both onshore and offshore wind energy facilities. For example, our industry-leading avian radar and bat acoustic monitoring equipment enables us to gather the most comprehensive data available without the costs of more labor-intensive methods. Our ornithologists and bat biologists are also highly recognized experts in their respective fields with years of training and advanced certifications. Our highly capable botanists and wetland biologists have performed vegetation studies and rare plant surveys, and have completed wetland ecological and aquatic resource investigations on projects of all sizes. They have developed successful approaches for cost-effective studies of frequently changing project layouts. Tetra Tech’s extensive field experience with the protection of fish habitat, and excellent working relationships with regulators, are reflected by the confidence with which agencies receive our work. Our biological staff has the ability to mobilize rapidly to ensure completion of time-critical surveys and assessments. Tetra Tech’s capability as a full-service provider for wind energy development allows for close coordination between our biologists and wind farm engineering designers, so critical environmental investigations can be conducted and completed in an integrated, efficient, and timely manner. Development Services Cultural resource Studies Tetra Tech’s archeologists and architectural historians have the national, state, provincial, and regional expertise and permitting experience to perform inventory surveys and testing for identifying historic properties within any project area. Our studies satisfy the requirements of state guidelines, agency guidelines for compliance with Section 106 of the National Historic Preservation Act, and provincial requirements to perform heritage research and conduct archaeological impact assessments. Our staff’s qualifications exceed those stipulated for cultural resource professionals by the U.S. Department of the Interior, allowing us to provide services such as: archeological and historical architecture studies; National Register of Historic Places evaluations and nominations; cultural resources monitoring; project impact assessment (National Environmental Policy Act (NEPA) and state equivalent analyses); and cultural resources awareness training. We have extensive experience assisting clients with consultations with State Historic Preservation Offices and other regulators. For projects in Canada, our staff are specifically trained and qualified to retain any necessary permits or licenses to conduct archeological studies. We also have experience in consultations with Native Americans, First Nations, and other Aboriginal groups. Heritage and Cultural resource Studies Tetra Tech’s archaeologists and architectural historians have national, State, and provincial expertise and permitting experience to perform Heritage Resource Impact Assessments. These assessments identify archaeologically significant areas and are required for environmental permitting. Our study methodology is designed to comply with various State and provincial requirements, with staff members specifically trained and qualified to retain the necessary licenses to conduct these studies. noise assessments Tetra Tech performs acoustic research, noise and vibration assessments, and data acquisition services for acoustic measurements. The assessment of wind turbine-generated noise is an integral component of provincial and local permitting. Tetra Tech’s engineers and scientists work closely with clients during the design phase to identify potential noise constraints. Acoustic modeling employs state-of-the art three-dimensional software which produces color sound contour maps ideal for permit applications and use in public presentations. We are also able to address the unique set of acoustic issues presented by offshore wind project development, including hydroacoustic baseline and operational surveys and underwater sound propagation modeling. Resultant data are routinely used in the assessment of behavioral response of marine life to new or increased levels of anthropogenic noise. Development Services Shadow Flicker assessments Tetra Tech uses WindPro to evaluate potential shadow flicker impacts from the project turbines at sensitive receptor locations surrounding the project. Our scientists incorporate on-site meteorological data into the WindPro analysis to predict expected shadow flicker impacts by calculating the relative frequency with which the turbine blades are moving, the frequency the blades are oriented in a particular direction, and the historical percentage of sunshine hours in the project site area. The predicted shadow flicker impact results can be presented graphically. visual impact assessments Conducting an objective, thorough, and well-illustrated visual resource assessment is a critical component of a wind project’s public outreach effort and environmental review. Tetra Tech provides state-of-the-art visual impact studies that meet the technical and procedural needs of permitting authorities, illustrating to stakeholders how the project will appear, and from which angles it will be visible. Our technical specialists are well versed in the application of visual resource systems and can complete visual impact studies to address the requirements of federal, State, provincial, and local agencies. Our specific services include landscape, viewer population, and existing visual quality characterizations; identification of key viewpoints and travel routes; photographic documentation of baseline visual conditions; viewshed/visibility mapping; formal visual impact analysis; photo-based simulations of “with-project” visual conditions; and evaluation of mitigation measures for identified visual impacts. Federal Aviation Administration (FAA) Lighting Plans Planning and development of wind energy projects must include consideration of FAA requirements to maintain aviation safety. Key policies include the requirement to notify the FAA of the proposed construction or alteration of any structure that may affect the national airspace system (typically any structure over 200 feet in height) and to follow FAA guidelines for marking and lighting of such structures. Tetra Tech’s portfolio of wind energy services includes preparing lighting plans for wind projects that comply with the FAA recommendations. Development Services Transport Canada (TC) Lighting Plans Planning and development of wind energy projects must include consideration of Transport Canada requirements to maintain aviation safety. Key policies include the requirement to notify TC of the proposed construction or alteration of any structure that may affect the national airspace system (typically any structure over 200 feet in height) and to follow TC guidelines for marking and lighting of such structures. Tetra Tech’s portfolio of wind energy services includes preparing lighting plans for wind projects to comply with the TC regulations. interference assessments Interference considerations include identifying areas where communication (microwave pathways or broadcast zones), radar, or aviation constraints exist. To help our clients protect communication resources, Tetra Tech employs the Radio Advisory Board of Canada (RABC) and CanWEA Technical Information and Guidelines on the assessment of the potential impact of wind turbines on radiocommunication, radar, and seismo-acoustic systems. Environmental assessments and Permitting At Tetra Tech, we excel in understanding the regulatory process. We know a successful permitting process must be integrated with engineering and constructability considerations to ensure that permits allow for a project owner to build the design that is ultimately depicted on the construction drawings. Our approach incorporates a tightly managed schedule, often dependent upon accurate planning of seasonal resource studies, and an understanding of the important differences in documentation and mitigation planning required by various federal, provincial and local permitting agencies. We are familiar with the wide geographical variations in permitting requirements across the US and Canada and with the regulatory bodies. We pride ourselves in permitting practical, economic and constructable projects—routinely saving our clients money by identifying the most cost-efficient development approaches. Community and aboriginal Engagement Meaningful and effective community and Aboriginal engagement is expected to be initiated by the proponent of a project undergoing environmental assessment at an early stage and continue throughout the life of the project. Tetra Tech’s staff are experienced in assisting developers with shaping and delivering messages regarding a project’s environmental and economic benefits. Public relations staff are part of the project team, ensuring positive messages are incorporated, as much as possible, into our technical deliverables. We work with our clients Development Services to identify project stakeholders and key issues, and we plan and facilitate newsletters, bus tours, open houses, public meetings, and other opportunities for constructive dialogue. We develop a variety of effective educational materials (including interactive CD-ROMs and client Web sites); handle media relations; and coordinate with federal, provincial, and county/municipal representatives. Tetra Tech has been successful in engaging Aboriginal communities in projects across the US and Canada. Engagement has involved the facilitation of discussion amongst our clients, various community leaders, and Aboriginal organizations; the establishment of resource sharing agreements; and conducting traditional knowledge assessments for inclusion in environmental scoping and permitting reports. Public involvement Gaining public and government acceptance of wind projects keeps them on track for successful permitting and development. Tetra Tech’s experienced public involvement specialists work with developers to shape and deliver messages about the environmental and economic benefits of proposed projects. Tetra Tech’s staff encourage project proponents to initiate meaningful and effective engagement with the community, including Native American tribes and Aboriginal peoples, early and throughout the life of the project. Tetra Tech has been successful in engaging Aboriginal communities across Canada, and Native American tribes throughout the United States. Engagement has involved the facilitation of discussion among our clients, various community leaders, Aboriginal organizations, and Native American tribes; establishment of resource sharing agreements; implementation of traditional knowledge assessments; and performance of surveys to identify Traditional Cultural Properties. Tetra Tech works with project proponents and community stakeholders to ensure agreed upon pertinent information is included in environmental scoping and permitting documents, while sensitive cultural information remains confidential and out of the public domain. Development Services EnGinEErinG At Tetra Tech, our engineers are part of the project team from the outset in order to ensure money is spent on environmental study and permitting of project layouts that support an economically constructable, safely operated project. Engineering Studies Our staff members complete various analyses and studies to support developers in the feasibility assessment of a new wind project. Power system studies assess the impact of wind generators and ensure network conditions will allow the wind generators to connect to the grid. We also evaluate the effect of embedded generation to ensure network conditions will allow the wind generators to operate effectively. These studies include load flow, fault calculation, transient stability, electromagnetic transient, and simulation of distorted wave forms. Power quality studies illustrate how the new generation affects the existing power grid. Optimization studies can be completed for the collections system and/or the transmission connection. Conceptual Design With input from various disciplines, our team of professionals prepares the wind farm’s conceptual design. Supporting the development of the conceptual stage, design and construction staff members complete a review of the proposed turbine configuration, electrical collection system, access roads, and overall wind farm layout. Staff evaluate the slope, terrain, and geotechnical aspects of the layout (at a desktop level), with the ability to access the proposed locations for a cost-effective road design, and the constructability of the proposed layout. This early review and assessment at the developmental stage is complimentary to environmental studies and other micro-siting tasks, and confirms the viability of both wind farm construction and operation. Generation Connection Our staff have comprehensive knowledge and practical experience meeting the technical requirements for connection to the grid, as well as an understanding of the project status with regards to the regulatory requirements and processes. We work with the local grid owner/operator to facilitate the connection process by reviewing the generation developer’s design to ensure compliance with applicable standards. This allows developers to make sound business case decisions during the early stages of a project, and ensures timely and accurate deliverables. Development Services Geotechnical and Seismic Studies and Designs Tetra Tech’s geotechnical expertise identifies criteria necessary for safe and economic wind turbine foundation designs. Modern wind turbines produce extremely high bearing loads and have very stringent requirements that must be accommodated by underlying geologic formations. Our geotechnical experts start with the understanding of local geology and follow through with tailored geophysical and geotechnical characterizations through site investigations and laboratory testing. These investigations also encompass requirements for the development of access roads, ancillary foundations, substation foundations, and electrical components. The results of site investigations form a basis for engineering analyses that feed into engineering and construction recommendations. transportation Studies, Planning, and Permitting Transportation studies and planning activities are performed early in the preliminary design phase. The activities include the evaluation of vehicle load and dimension restrictions; impacts from railroads, bridges, and culvert crossings; impacts from grade separations; and impacts from utilities. Transportation permitting requirements often include several levels of government and jurisdictional bodies. By completing the studies, planning, and permitting early in the project, adverse impacts on subsequent detailed design and construction schedules can be avoided. Detailed Design - roads, Foundations, Electrical Civil Site Engineering Our talented team of engineers and technical staff ensure every facet required for the civil works are completed with diligence and an eye towards economic construction. Road and turbine site design is critical for the safe delivery of the oversized turbine components and appropriate access for the cranes. Design consideration must also be given to minimize environmental impacts to wetlands and surrounding land use. Every detail from cut and fill calculations through to entrance radii and specific data required for transportation permitting is given due consideration in the design. Beyond site design, our civil team reviews the site and prepares a comprehensive erosion and sediment control plan and stormwater management control program to protect the site throughout construction and the life of the project. Structural/Foundation Engineering While Tetra Tech maintains a library of safe, successful and cost-effective foundation designs, it is very rare that a design for a wind project can be "off-the-shelf." Different site conditions often require individually tailored solutions and when faced with a challenge, creativity and innovation supersede. With so many projects under our belt, our staff have developed standard wind turbine foundation designs that can be adapted and modified to suit any site’s specific conditions. This has proven to be an efficient process, with effective results. We strive for the same efficiency with designs for substation facilities and site operations and maintenance (O&M) buildings. Electrical Engineering Tetra Tech provides complete electrical engineering and design services for wind energy projects including the collection system, substation, transmission, and interconnect facilities. From basic single-line conceptual designs and capital cost estimates, through to comprehensive design packages, complete with equipment specifications and material lists, our team meets the project’s requirements with technical design excellence and equipment selected for top performance. We review critical inputs such as geotechnical resistivity data to develop secure grounding designs. As well, our designs incorporate advanced telecommunications equipment and SCADA for real-time monitoring of the system’s protection and control mechanisms, enhancing safety and reliability. Development Services ConStruCtion Constructability review Tetra Tech helps clients develop constructible wind projects because of the integrated approach taken with our environmental and engineering teams. Our construction experts review the project site and proposed developmental designs in order to ensure safety, practicality, and ease of construction are addressed in the project layout that is ultimately permitted. Conceptual and Final Budgets and Schedules Tetra Tech’s construction experts can assist project developers by providing conceptual stage construction schedules and Rough Order of Magnitude estimates that closely model actual construction costs. Our clients use this information to support project financing, fiscal planning, power pricing, and competitive bid pricing for power purchase agreements. Working with Local County/Municipal Officials From past experience, we’ve learned it is crucial to involve the local county/municipal planner(s) to ensure the project moves forward as planned. Even minor issues with the planners can lead to substantial delays that could impact cost and schedule. To the benefit of the project, some planners are able to provide up-to- date, accurate land mappings, ensuring no details are missed at the planning stage. Construction Permitting Construction permitting for wind projects varies from state to state, province to province, and municipality to municipality. In addition to general project permitting and permits required to construct the operations and maintenance facility, it is not uncommon for some authorities to require permits for each turbine. This requires close coordination and careful planning to ensure these requirements are met without any delay to the overall construction schedule. Development Services EnvironmEntaL Environmental Compliance management and inspection In an increasing number of jurisdictions, wind energy companies are required to provide environmental compliance management and inspection during construction. Compliance issues during construction can lead to expensive stop-work orders, as well as civil and criminal penalties. Using a wind project’s permit and other commitments, Tetra Tech’s experienced planners prepare compliance tools to keep the construction on schedule and within budget. We train construction crews, project owners, and agency representatives in environmental compliance management, and provide on-the-ground inspectors who work proactively with construction crews to resolve potential compliance issues. Should an issue be identified, Tetra Tech maintains expert project teams in-house, allowing us to immediately address and resolve the problem. EnginEEring Designing for Construction The combination of Tetra Tech’s engineering and construction experience for wind projects allows us to provide our clients with cost-effective designs that incorporate the forethought of constructability, regardless of what unique challenges the site may possess. We provide the right level of detail and information in our drawings to allow a constructor the necessary flexibility during execution, but with sufficient details on the specific features of the project. Subcontractor/vendor Submittal reviews Items for which technical specifications are developed generally require the submittal of specific material, equipment, and/ or system information for review prior to acceptance. As both designer and constructor of wind farm projects, Tetra Tech has the expertise to properly review these submittals to ensure the proposed materials, equipment, and systems meet the outlined requirements. response to requests for information and Field Change requests During construction, contractors often submit Requests for Information (RFI) in instances where additional information or clarification of the design intent is needed. With Tetra Tech’s depth of experienced professionals, we can review the RFI and respond in a timely fashion, which allows the field/construction team to continue working without an interruption in work flow. Sometimes Field Change Requests (FCRs) are needed because of land owner requests, non-conforming geotechnical conditions, or even requests from the OEM (original equipment manufacturers) vendors. Some FCRs are minor and do not affect the intent of the original design, such as equipment, component, system, or structure that relates to function, operation, or safety. In other instances, the FCR might be major—affecting the intent of the original design. In either instance, our team has the capability to provide complete support to minimize any impact to the project’s delivery. management of Construction and Design Changes When design changes are required during the construction phase, Tetra Tech’s experienced engineers are able to work directly with the construction team and develop the necessary drawings and reports to communicate the changes. Quality is never compromised. All implications of design changes are properly reviewed before direction is given back to the construction site. Because we’ve supported projects with both engineering and construction, this process occurs in an efficient manner to minimize any impacts on the overall project schedule and budget. Renewable eneRgy ▪ windConstruction Services as-Built Drawings As-built drawings capture the constructed condition upon turnover to the client. The process of developing as-built drawings starts with the field engineering services staff, who “red-line” design drawings during the construction process as field modifications are made. On projects where Tetra Tech is the engineering firm, these marked-up drawings are then turned over to our in-house engineering/design team for development of electronic as-built drawings for final presentation to the client. Field Services Seasoned staff from various disciplines use their hands- on, practical experience to provide quality oversight, quality assurance, inspection, and field engineering and testing services. These services include performing site walk-throughs during construction to provide onsite clarification to construction resources, and recommendations for modifications or changes based on field conditions. Our experience as an EPC (engineer, procure, construct) firm brings the benefit of engineering and construction experts who have worked together in providing clients a complete team and comprehensive approach. Construction Field Staking Every wind turbine and access road needs to be clearly staked to ensure proper adherence to the approved drawing plans. Our field services staff take extra care to ensure every detail matches the project plans. This protects the public and land owners, and ensures adherence to the geotechnical engineers' recommendations for wind turbine foundation placement. Construction Services Construction Services ConStruCtion Tetra Tech offers a construction team with the depth of qualified resources to safely build access roads, electrical collection systems, and substation(s), and erect wind turbine generators— everything required for a wind generating facility—in a cost- effective manner.

Construction Services Project management It is one thing to say you can do something; it is another to deliver. And it is something entirely different to be able to manage, communicate, and instill confidence that you are delivering what was promised. Quality project management is a combination of processes, tools, and talented people who understand the full scope of commitment—an integrated schedule with overlapping milestones, fixed budget, and clearly defined deliverables. Tetra Tech employs established tools to provide real-time information for schedule and budget analysis; utilizes proven processes for document control, change management, and project management controls; and prepares comprehensive reports and communications so the client is fully aware of the project status. But it is our project managers, with their practical and reputable experience managing wind power projects, that make it all happen. Procurement Tetra Tech’s procurement specialists provide innovative procurement solutions. With relationships throughout the industry, they can obtain excellent pricing and delivery terms on all major wind farm components. We offer a full line of procurement services, including procurement strategy, preparation of Request for Proposal/Scope of Work packages, and evaluation of vendor proposals. When engaged, our procurement staff will negotiate, coordinate, complete contract administration, organize logistics, and implement quality assurance, quality control, and materials management practices. In addition, Tetra Tech can prequalify subcontractors for safety and other qualifying factors. These are the same services used within our EPC model to support contractually obligated completion deadlines. and Environmental Technology Programs, and International Organization for Standardization (ISO) 9001-2008 programs. Aligned with these QA/QC models, our quality standards are established at the highest levels of management to deliver projects that are within scope, defect-free, on time, within budget, regulation-compliant, and that offer the greatest value to our project owners. We administer these standards by dedicating skilled and experienced QA/QC Officers to our projects. The QA/QC Officers implement Tetra Tech’s well-defined Quality Control Program on site, overseeing and measuring it against the performance of the project team. The Officers are responsible for developing and enforcing project-specific QA/QC Plans which meet project requirements. They conduct quality inspections, project quality training orientation sessions, and on site meetings to reinforce QA/QC procedures throughout the construction process. They document and work diligently to resolve any and all quality concerns. They work closely with the rest of the project management team to ensure every person working on a Tetra Tech renewable energy project knows what to do, how to do it, and the processes for correction of deficient work to ensure the quality we demand for our clients. Routine project audits are performed by senior quality management staff to ensure the proper implementation of corporate and project procedures. Land owner management/relationship Relationships with the land owners require management throughout the course of the construction period. Prior to engaging in construction activities, we hold multiple information sessions (usually in the evenings) at either a local establishment or at one of the local land owners’ homes. We review with the land owners the developed and approved plans for the individual properties. Many times, the land owners will come up with a clever way of routing the access roads so they can maximize their land use. Health and Safety Planning and training Health and Safety (H&S) is not just another program at Tetra Tech—it is integral to our culture and incorporated into all facets of our work. We believe all behaviors are manageable on site, and therefore, all incidents are preventable through our tenets, of “Do It Right” and “Zero Incident Performance.” Our past year’s performance has brought us industry recognition as one of the 40 Safest Firms in the Heavy Construction Industry as we approach several million hours worked without lost time injury. We firmly believe and demonstrate daily it is possible to conduct work injury and incident free. Tetra Tech’s Health and Safety program exceeds compliance with United States OSHA and Canadian Provincial Worksafe statutes and jurisdictional regulations. Our H&S program has received OSHA VPP status on project specific bases and cooperates regionally on informal partnerships partnerships with OSHA, CSA and joint provincial industry safety and health committees and working task groups in Canada and the US and have been recognized by USACE, DOD and federal agency reviews for excellence. Additionally we work with North American trade associations and industry groups, such as ANSI, to drive construction industry safety standards in North America improving working environments for labor and results for contractors as well. Project-specific, comprehensive, H&S programs are implemented for all project scopes. We maintain detailed procedures for conducting risk assessments and Activity Hazard Analyses to ensure hazards are proactively eliminated or minimized. Project Safety Officers are appointed to coordinate all H&S activities and training. All field employees receive thorough orientation and ongoing training throughout project execution and as conditions change or warrant. Daily Activity Plans incorporate safety planning with work flow and tool box talks are performed for further emphasis. Weekly Quality Circle meetings integrate further our tenets to provide a forum in which to review substandard behaviors resulting in near misses of safety or quality nature, as both are integral to overall success. Risk assessment and hazard identification ultimately become the responsibility of every individual on site in “Shared Vision” and responsibility as all benefit in the results. Quality assurance/Quality Control (Qa/QC) On our renewable energy projects, managing quality is not one person’s job…it is everyone’s job. At Tetra Tech, we believe our success can only be measured by client satisfaction of the quality of our services. We strategically manage quality through planning, execution, and closeout to satisfy the requirements and expectations of our clients, our communities (or stake holders), and (the toughest customer of all) ourselves. Our QA/QC standards are based on American National Standards Institute/ American Society for Quality (ANSI/ASQ) E-4 - Specifications and Guidelines for Quality Systems for Environmental Data Collection Construction Services EnvironmEntal Post-Construction Environmental Services Tetra Tech offers a full selection of environmental services for post-construction project needs from developing operation compliance plans and programs, to training owner’s staff, to providing on-the-ground expertise. We have regulatory, biological, hydrological, cultural resource, socioeconomic, hazardous material, and other staff available to address any potential environmental issues a wind project might experience during operations. monitoring and Compliance After wind projects are complete, permit conditions or lease provisions often require environmental aspects of the project to be monitored to determine the success and/or performance of mitigation measures, and document, over time, the actual environmental impact of project operation. Tetra Tech performs post-construction wetland, fish habitat, wildlife, vegetation, and agricultural monitoring, as needed, to ensure the success of mitigation and restoration efforts, and identify areas in which adaptive management may be required. Tetra Tech also designs and implements post-construction wildlife monitoring protocols, including the avian and bat mortality monitoring that is often required for operating wind power generation facilities. EnginEEring Substation and transmission lines Asset Management Once the facilities are constructed, the owner’s goal transitions to that of maximizing the life and operations of the asset. A strategic component of achieving this goal is a well-defined asset management plan. A properly developed plan encompasses the individual equipment and their associated life-cycles, specific maintenance requirements, and the interdependence of those components and their criticality to reliable and safe operations. Tetra Tech's staff has extensive experience with the operations and maintenance of these assets. We can help develop an asset management plan to ensure the facility achieves and possibly exceeds its planned life. Condition Assessment Throughout the course of the facility’s life, the infrastructure and equipment age at specific rates. The structural infrastructure of the building will have a different life expectancy than that of a transformer or an overhead line, so the same yard stick cannot be used to measure all three. Our team can perform condition assessments to qualify the components, rate of deterioration, remaining life, and what remedies can be applied to resolve the issues or extend its life. Investigating and Solving Operations and Maintenance Issues There are sometimes occurrences when the facility isn’t performing the way it is expected without a clear indication of why. When the why isn’t obvious, our employees have the practical knowledge and experience to troubleshoot performance issues— identify the root cause and prescribe measures to address and correct the problem. Rehabilitation, Replacement, and Upgrade As equipment ages and regulations change, it may be necessary to rehabilitate, replace, and/or upgrade to maintain optimum operations and safety. Tetra Tech's staff can design and oversee the rehabilitation, replacement, and upgrade of the assets.

In April 2010, Acciona Wind Energy Canada awarded Tetra Tech a Balance-of-Plant contract ($30 million) for the 45 MW wind farm located on Lamèque Island in New Brunswick. The site, comprised primarily of peat bogs and blueberry farms, measures 3,100 acres and hosts 30 wind turbines, each with an output of 1.5 MW. The site provides approximately 140 gigawatt hours annually, enough power to meet the electricity needs of about 8,900 homes. Specific to the contract, Tetra Tech’s scope of work included: 19 km of tower roads concrete foundation installation tower erection trench installation of 34,000 meters of cable and 121 meters of grounding substation facilities SCADA and MET tower installation office and O&M facilities storm water pollution prevention plan installation, compliance, and maintenance reclamation work All work was completed in compliance with municipal, provincial, and federal permits and regulations. The wind farm connects to the grid via a 69 kV transmission line constructed by the local utility. The Lamèque Wind Power Project is ACCIONA Energy's fourth wind farm in Canada, adding a distinctive feature in the Gulf of St Lawrence. Lamèque Wind Power Project NEW BRUNSWICK PROJECT CHALLENGES The project is situated on peat bogs, which challenged excavations and roadways. We were required to undercut some of those areas and place additional stone/fabric. There was limited workspace within the roads and foundations The project is encompassed by blueberries, a local cash crop, so special attention needed to be paid throughout construction to ensure limited crop damage The project site is located on an island, which challenged the logistics of material delivery The project had a very aggressive schedule Severe winter construction conditions There were more than 60 landowners involved with interest in the project PROJECT EXPERIENCE Offshore Services V4 April 2011 Copyright © 2010, 2011 Tetra Tech EC, Inc. As a member of NRG Bluewater Wind, LLC’s (Bluewater Wind or Bluewater) world-class network of global offshore wind experts, Tetra Tech has supported the siting, environmental evaluation, and preliminary permitting efforts in support of their currently proposed offshore wind projects along the East Coast of the United States including: Preliminary siting and environmental constraints and permitting analyses for projects proposed in the state of Rhode Island, as well as five sites along the Atlantic Coast and Great Lakes of the United States. Siting, environmental evaluation, and preliminary permitting of the Bluewater offshore wind park, meteorological data collection facility (MDCF), and interconnection facilities off the coast of Delaware—the first utility-scale wind park project in the United States to obtain a long-term Power Purchase Agreement (PPA) and one of the first to receive a Bureau of Ocean Energy, Management, Regulation and Enforcement (BOEMRE, formerly the Minerals Management Service (MMS)) Interim Policy Limited Lease. Siting, environmental evaluation, and preliminary permitting of the Bluewater offshore wind park, MDCF, and interconnection facilities off the coast of New Jersey—one of the first utility-scale wind park projects in the United States to obtain a BOEMRE Interim Policy Limited Lease and one of only three projects to receive a development grant from the State of New Jersey. Specific services provided in support of Bluewater’s offshore renewable energy development efforts have included conducting critical issues analyses (CIAs), onshore and offshore transmission route feasibility studies, and regulatory permitting analysis, negotiation, and acquisition. To support project siting and feasibility analyses, Tetra Tech has evaluated onshore constraints such as impacts to terrestrial wildlife and vegetation, parks, nature preserves and other areas of recreational interest, residential developments, agricultural areas, wetlands, historic sites, and viewsheds. Evaluation of offshore constraints has included impacts to marine life (e.g., marine mammals, sea turtles, and fish), significant marine habitats, avian and bat species, navigation areas, submerged cultural resource sites, dump sites, unexploded ordnance, cable crossings, and commercial and recreational fishing areas. Specific agency interactions in support of the evaluation and permitting of the Bluewater projects have included consultations and negotiations with agencies such as the BOEMRE, the US Army Corps of Engineers (USACE), the US Fish & Wildlife Service (USFWS), the National Marine Fisheries Service (NMFS), the United States Coast Guard (USCG), and a number of state environmental agencies. NRG Bluewater Offshore Wind Parks Along the East Coast United States PERFORMANCE HIGHLIGHTS Prepared successful BOEMRE Interim Policy Limited Lease Applications and obtained required federal, state, and local permits Successfully initiated off-shore avian surveys at the proposed project site off the coast of Delaware — the first comprehensive offshore wind park avian study conducted in federal waters off the coast of Delaware Support will continue through BOEMRE leasing and National Environmental Policy Act (NEPA) environmental permitting process PROJECT EXPERIENCE Wind – WEI V2 May 2011 Copyright © 2010, 2011 Tetra Tech EC, Inc. Tetra Tech Engineering Inc. supports renewable power generation developers with a variety of services related to generation connections: Conduct grid integration feasibility studies, including possible routes for transmission circuits and connection points Prepare grid connection applications and provide support throughout the process Act as a liaison between client and regulatory agencies Prepare conceptual design and capital cost estimates Design the collection system, substation, and balance of plant Prepare equipment specifications, including vendor bids and technical and commercial evaluation Design the transmission and distribution circuits from the developer’s site to the grid connection point Our vast experience means our staff draws upon a comprehensive understanding of the developer’s ultimate goals for the proposed generation site, providing timely and accurate deliverables. The foundation of these deliverables is based on a thorough analysis of the impact assessment the new generation will have on the existing grid system and the project’s overall feasibility. We can provide preliminary cost estimates and conceptual design for generation facilities, lines, and grid connections, allowing generation developers to make sound business decisions during the early stages of a project. Our focus is on the technical requirements for connection to the grid, and the status of the project with regards to the regulatory requirements and processes. We conduct power studies that support grid interconnection assessments on projects under various stages of development. We work with the local transmission owner/operator to facilitate the connection process by reviewing the generation developer’s design to ensure compliance with applicable standards. Our team members review the proposed grid connection points and any existing study reports to ensure connection requirements are met, such as capability to supply reactive power and operate within a voltage and frequency range; protection, control, and relaying; and monitoring and telemetry. Beyond generation connection, we support our clients in an advisory capacity. We review framework agreements and contract documentations to identify areas of risk, and will act as a third-party expert advisor in relation to the acquisition and value attributed from the assets related to electrical engineering or grid connection. Tetra Tech has worked with both generation developers and transmission/distribution utilities on the integration of wind, solar, thermal, and hydro generation for 350 projects ranging from 10 MW up to 1000 MW, including: wind farms solar projects waste-to-energy plants co-generation plants thermal generation plants hydro generation plants Services include various power studies, preparation of connection impact and system impact assessment applications, and due diligence assessments. Generation Connection PROJECT EXPERIENCE Tetra Tech provided environmental construction compliance, Phase 1a and 2 permitting, value and design engineering, and civil construction services to Flat Rock Windpower, LLC (composed of Horizon Wind Energy and Iberdrola Renewables (formerly PPM Energy)) for the Maple Ridge Wind Farm in Lewis County, New York. The completed project consists of 195 Vestas 1.65 megawatt (MW) turbines with a 12-mile 230 kilovolt (kV) Article VII transmission line. In less than four weeks, Tetra Tech reviewed 38 environmental permits and dissected them for any construction-related environmental compliance measures. Working side-by-side with our client, we developed a program to meet all environmental construction requirements in the most efficient manner possible. We presented the compliance program, the first ever done in New York for a wind farm, to the enthusiastic approval of the New York State Department of Public Service, the New York State Department of Environmental Conservation, and the New York State Department of Agriculture and Markets. We trained 450 construction workers, agency personnel, and owner personnel in how to use the environmental compliance tools we created. And, most importantly, Tetra Tech obtained every preconstruction clearance that was part of our scope of work two days ahead of schedule. Tetra Tech provided environmental construction inspection services throughout construction, keeping the project in compliance and construction moving forward. These services included construction observation, environmental training, obtaining regulatory approval for project changes, and environmental reporting.

PROJECT EXPERIENCE Wind – WEI V2 April 2011 Copyright © 2010, 2011 Tetra Tech EC, Inc. Acciona Energy North America engaged Tetra Tech to assist them with completion of the environmental review for the proposed Aulac Wind Farm. This review included the performance of fall migration surveys for raptors and waterfowl, expanding the existing Avian and Bat Protection Plan (ABPP) to include detailed pre- and post-construction monitoring plans, and liaison with federal and provincial regulatory agencies to complete the regulatory review process. Monitoring started in September 2010 and continued through November 2010 at locations selected to provide coverage of areas of specific interest within the project area, Rapid-response data entry allowed for rapid notification if species of interest were detected during the surveys. The pre-construction surveys, when combined with existing data, provide baseline information that will be used to predict which species may be vulnerable to turbine collision and other potential project impacts. Tetra Tech will review all existing information to identify data gaps relative to potential avian issues, and address issues raised by the Canadian Wildlife Service (CWS) and the New Brunswick Department of Environment (NBENV). We will then tailor Acciona’s existing Master Avian and Bat Protection Plan to include: A focus on Canadian and New Brunswick legislation, regulations, and permitting procedures Explicit pre- and post-construction monitoring plans (including post-construction mortality monitoring) An adaptive management plan based on pre- and post- construction monitoring data Aulac Wind Farm NEW BRUNSWICK, CANADA PROJECT EXPERIENCE Wind – WEI V3 May 2011 Copyright © 2010, 2011 Tetra Tech EC, Inc. Tetra Tech’s multidisciplinary engineering team has been providing services to Yukon Energy Corporation (YEC) since 2007 in the areas of civil, structural, electrical, design, construction management, system studies, and procurement in support of the Carmacks to Stewart Crossing transmission line project. Background Yukon Energy is building a new 138 kV transmission line from Carmacks to Stewart Crossing in the Central Yukon (approximately 172 kilometers long), with a spur line to the Minto Mine substation in order to provide reliable power to consumers along this route and in other areas. Scope of Work Tetra Tech is supporting YEC throughout the life cycle of this two phase project, providing comprehensive power system studies, capital cost estimate, detailed design, construction management, and procurement services. The engineering design phase began in 2008, connecting the Whitehorse-Aishihik and the Mayo-Dawson transmission lines. The project includes a new 138 kV transmission line, a 25 kV spur line, and new transmission substations at Carmacks, Pelly Crossing, Minto Landing, Stewart Crossing South, as well as expansion to the existing substation at Stewart Crossing. This will enable the local consumer, such as Minto Mine, to access hydro-electric power rather than rely on diesel generation, enhancing overall reliability and flexibility to the area. Tetra Tech’s Procurement Group, in conjunction with YEC, established commercial, general, and special conditions for the specification and purchase of equipment and materials. Project challenges have included minimizing environmental impact, innate northern climate and geography, managing stakeholder interests, and tight project timelines. In regards to the engineering of transmission lines, many factors were considered at various project stages to ensure the project was technically feasible as well as practical and cost-effective in its construction and maintenance. Tetra Tech evaluated and quantified the pros and cons of different routing alternatives and assisted YEC in selecting the best solution. Cost and quantity estimates and project schedules enabled YEC to understand the financial commitment, procurement requirements, and timelines to ensure the project was properly supported. The Tetra Tech team established a complete design criteria including applicable loading cases, clearances, and safety margins. All required studies and calculations, such as system load flow, short circuit, ampacity, corona, radio interference, galloping, and maximum electrical span, were conducted by the team to build a solid design basis document. The team determined the optimal line material and appropriate structure types, along with quantity and heights, span lengths, foundation structures, and temporary civil requirements for line construction. Among several tools used to develop reliable and optimum line design, the team employed PLS-CADD for line routing—providing plan and profile drawings, structure spotting, staking, sag tension and structure, and section strength analysis reports. Tetra Tech prepared formal tender-ready packages with drawings for the guying, structures, and pole extensions, with complete bill of materials; provided support throughout the construction phase; and prepared as-built drawings. Carmacks-Stewart Transmission Line Project YUKON PROJECT EXPERIENCE Wind V2 May 2011 Copyright © 2010, 2011 Tetra Tech EC, Inc. Tetra Tech integrated our well-established environmental consulting and permitting support with our in-house engineering and wind construction services to provide a full- service team to Competitive Power Ventures (CPV) for the Keenan II Wind Energy Project. The project is located in Woodward County in northwest Oklahoma. Tetra Tech performed a detailed Critical Issues Analysis of the proposed project site to identify potential fatal flaws, determine applicable permitting requirements, and establish next steps for successful project development. We then completed a number of additional environmental studies to support successful development and minimize impacts and project costs. These included bat risk assessment; whooping crane risk assessment; lesser prairie- chicken lek survey; cultural resource file review at the State Historic Preservation Office, Oklahoma Archeological Survey, and Woodward County offices; Unanticipated Discoveries Plan for historical remains; Phase I Environmental Site Assessments; and numerous geographic information system and mapping efforts. Tetra Tech also conducted the wetlands investigation and delineation in conjunction with design of the final project layout. Protected resources were identified and avoided to the maximum extent possible in order to minimize impacts, permitting requirements, and associated costs. Tetra Tech represented CPV at landowner open houses and agency meetings by presenting project data and addressing local, state, and federal questions and concerns. Project management, technical, and senior Tetra Tech staff were also on-call during the closing financial negotiations to support the client with any last minute issues and questions. Based on our success with the environmental studies and our strong client relationship, Tetra Tech was then awarded the $40 million engineering, procurement, and construction (EPC) contract, and began construction of the Keenan II Wind Energy Project.

The Castle Rock Ridge Wind Power Project involved determining general subsurface conditions at the locations of 33 proposed wind turbine towers (Enercon 2.3 MW), substation and road access. Tetra Tech’s scope of work included recommending: Design parameters for turbine tower foundations Raft and pile foundation alternatives Enercon foundations, as well as special considerations Casing and dewatering during construction Provisions for control of groundwater Backfill materials and compaction Roadways and crane pads Surface drainage criteria (around the foundations) Concrete type As well, our staff provided: Review of potential borrow sources in the area Civil specification and concrete mix design review Foundation inspection prior to mud slab placement Quality Assurance testing of concrete and backfill Castle Rock Ridge Wind Power Project Enel North America NORTH OF PINCHER STATION, ALBERTA PERFORMANCE HIGHLIGHTS Comprehensive soil investigation including borehole drilling in soil and bedrock, soil resistivity, seismic (MASW) and thermal conductivity testing Recommendations for foundation design and construction parameters Special considerations for Enercon, including deletion of their proposed granular layer under the bases Search for material sources in the area Foundation inspection during construction Quality Assurance testing of concrete and backfill PROJECT EXPERIENCE Tetra Tech provided a full suite of consulting and construction services to the Kodiak Electric Association, Inc. (KEA) during the development of this wind energy project on Kodiak Island, Alaska. The facility consists of three General Electric 1.5 megawatt (MW) sle wind turbines and sits atop Pillar Mountain, overlooking the city of Kodiak. Developed to operate in conjunction with local hydroelectric generation, the new Pillar Mountain wind energy project is an integral part of KEA’s vision of producing 95% of its energy sales with cost-effective renewable power solutions by the year 2020. Developing renewable energy facilities in the state of Alaska can be a challenge for even the most seasoned developer. These issues, often unique to Alaska, require significant assessment, planning, mitigation, and coordination. Tetra Tech prepared a Critical Issues Report and conducted an engineering feasibility study to assess and proactively address project issues, including transporting the project components to the top of Pillar Mountain and constructing the facility itself. These proactive efforts uncovered an issue with the existing gravel road to the top of the mountain. The road passed near a number of wetlands and waterways, and was too narrow to accommodate construction traffic and wind turbine delivery. Project access required significant rerouting and reconstruction of the road to accommodate transporting the heavy turbine components and equipment to the site. In addition, because the only access to Pillar Mountain was through Kodiak using existing main roads and residential streets, several Pillar Mountain Wind Energy Project KODIAK ISLAND, ALASKA PERFORMANCE HIGHLIGHTS Provided full field engineering-procurement-construction services for Alaska’s first large-scale wind energy project Performed feasibility study including the evaluation of the transportation route through the town of Kodiak and up Pillar Mountain, including seismic concerns and constructability issues Provided Professional Engineer seal and signature on Independent Engineer’s Certificate for Kodiak Electric Association’s (KEA) successful application for Clean Renewable Energy Bonds (CREBs) under the National Rural Utilities Cooperative Finance Corporation program through the Internal Revenue Service Performed turbine micrositing Performed complete geotechnical investigations and studies for the foundations, electrical grounding, and thermal resistivity characteristics of the site Provided narrative and engineering plans in support of the 404 permit application for wetland protection and on-site erosion and sediment control; the permit received prompt agency approval Completed civil and structural design including surveying for all scopes of the project Self-performed the foundation construction and conduit and grounding activities, including down tower wiring Pre- and post-construction avian studies focused on bald eagle use and behavior in relation to the turbines The National Rural Electric Cooperative Association (NRECA), which represents more than 900 cooperative electric utilities across the United States, selected KEA and the Pillar Mountain Wind Energy Project as its 2009 Wind Cooperative of the Year The Pillar Mountain Wind Energy Project was also a runner up for the Platts Global Energy Awards in 2009, and is the subject of a Discovery Channel special feature PROJECT EXPERIENCE Wind V3 April 2011 Copyright © 2010, 2011 Tetra Tech EC, Inc. intersections had to be modified temporarily to accommodate over-sized turbine delivery trucks. Tetra Tech helped coordinate turbine delivery with Kodiak officials and the police department, and their support of the project was timely and generous. The United States Fish and Wildlife Service (USFWS) expressed some concern about the presence of bald eagles in the Pillar Mountain area, and the risk of eagles colliding with turbines. The Pillar Mountain project is the only wind power project constructed to-date in an area where bald eagles are seasonally common. Tetra Tech designed and implemented a year-long field study of avian use and trained qualified local subcontractors to address these concerns. Tetra Tech is now conducting post-construction monitoring of bald eagle use in relation to the wind turbines. Early knowledge and understanding of the various challenges allowed the Tetra Tech team to support the client in developing the best strategy to achieve project success. In advance of construction, Tetra Tech prepared design drawings and provided supporting engineering analyses for the civil and foundation aspects of the wind turbine project. These efforts included evaluations on the potential for severe seismic and high wind effects on the foundation design and transportation in steep mountainous terrain. The team prepared the 404 permit application to submit to the United States Army Corps of Engineers (USACE), and received prompt agency approval. In the remote and austere Alaskan mountaintop location, construction efforts were limited to a few short months out of each year. In 2008, over the course of the first construction season, the Tetra Tech team constructed roads, crane pads, and erection areas; blasted and excavated turbine foundations; formed, reinforced, and poured three complete foundations; installed the foundation conduit and grounding system; excavated and backfilled the electrical collection system trench; and formed, reinforced, and poured the foundation for a 50-meter meteorological tower. In 2009, Tetra Tech successfully completed construction on the Pillar Mountain site. Tetra Tech established and managed detailed scopes of work and deadlines based on the delivery dates for turbines; qualified subcontractors; issued contracts; and mobilized teams to deliver turbines to the project site. Tetra Tech was responsible for the (Xworks) shipping of wind turbine components from fabrication facilities to an inland central location, combining the cargo and packaging for overseas shipping to the project location. Tetra Tech upgraded multiple areas of the public road to allow for delivery of turbine components to the project site. We successfully offloaded, cleaned, and erected three complete towers, including the tower wiring, and provided on-time mechanical completion for each tower. Since coming on line, the Pillar Mountain wind turbines have met or exceeded their electrical generation expectations. With a total generation capacity of 4.5 MW, the Pillar Mountain Wind Farm has produced more than 22,500,000 kwh of electricity and saved more than 1.58 million gallons of diesel fuel in its first year and half of operation. Based on the success of the Pillar Mountain Wind Energy Project and the escalation in diesel fuel costs, KEA has begun plans for a second phase where three more turbines would be added to Pillar Mountain and a third turbine added to the Terror Lake Hydroelectric Plant. Tetra Tech is participating in the planning for adding three additional turbines to the Pillar Mountain Wind Farm. The National Rural Electric Cooperative Association (NRECA), which represents more than 900 cooperative electric utilities across the United States, selected KEA and the Pillar Mountain Wind Energy Project as its 2009 Wind Cooperative of the Year. In addition, the Pillar Mountain Wind Energy Project was a runner-up for the Platts Global Energy Awards in 2009, and is now the subject of the Discovery Channel’s “Shades of Green” special feature.

Tetra Tech continues to provide a wide range of environmental support services to Granite Wind, LLC for the Granite Mountain Wind Project, a 62 to 81 megawatt (MW) wind energy project located 14 miles east of Victorville in San Bernardino County, California. Granite Wind, LLC is a subsidiary of Renewable Energy Systems Americas Inc. Tetra Tech worked closely with the Bureau of Land Management (BLM) to ensure potential impacts to natural resources were addressed. Our staff conducted the biological resource surveys necessary to evaluate environmental impacts to the area, including surveys for species of concern such as the desert tortoise and Bendire’s thrasher, habitat assessment for Mohave ground squirrel, and territory evaluation for golden eagles. Other environmental surveys included raptor nest searches, avian point count surveys, turkey vulture and raptor migration surveys, jurisdictional waters surveys, botanical surveys, and acoustic bat surveys and analysis. For the bat surveys and analysis, Tetra Tech successfully installed two Anabat detectors on the meteorological tower and passively collected bat calls for one year. Data collected was analyzed to determine bat activity in the project area, and evaluate potential impacts of the turbines to bat populations. Expanded requirements for golden eagle evaluation and protection led to additional data gathering on eagle behavior in the project vicinity in 2011, which are likely to extend into the Fall. These surveys are all part of our comprehensive environmental assessment of the potential impacts arising from the project development in accordance with the National Environmental Policy Act (NEPA) and California Environmental Quality Act. In addition, Tetra Tech currently is preparing an Avian and Bat Protection Plan (ABPP) that will include specific language for protection of golden eagles, and will be reviewed and approved by federal and state regulatory agencies. Tetra Tech prepared detailed reports summarizing the findings of each survey, and analyzed the potential impacts of the proposed project on local species and resources. To summarize and compile the biological resource survey results and provide a comprehensive evaluation of the environmental conditions of the site, Tetra Tech produced a general biological report for the client and the BLM.

Hardin Wind Project HARDIN COUNTY, OHIO PERFORMANCE HIGHLIGHTS Tetra Tech cultural resources staff scoped their field studies to minimize costs for the client and minimize the amount of time in the field as compared to standard approaches Tetra Tech mobilized crews and delineated wetlands along a 130 mile corridor in less that 10 days to meet the evolving requirements of the new OPSB rules Supported the development and finalization of a memorandum of understanding with the Ohio Historical Society PROJECT EXPERIENCE Wind V3 May 2011 Copyright © 2009, 2010, 2011 Tetra Tech EC, Inc. Tetra Tech provided comprehensive engineering, procurement, and construction (EPC) services to Oklahoma Gas and Electric for the OU Spirit Wind Farm. The project is located in Woodward County, Oklahoma and includes 44 Siemens 2.3 megawatt (MW) turbines for a total generating capacity of 101.2 MW. Tetra Tech was awarded a $36.9 million contract to perform civil, structural, and electrical engineering. In addition, we constructed 44 foundations, the collection system, a substation, an operation and maintenance facility, and roads. Tetra Tech also constructed nine miles of transmission line to support the project. In a unique agreement, Oklahoma Gas and Electric and Oklahoma University announced plans to purchase electricity generated from the OU Spirit Wind Farm. Oklahoma University’s Norman campus plans to achieve 100% renewable energy by 2013. The construction of the OU Spirit Wind Farm is a significant part of that agreement. The OU Spirit Wind Farm was previously known as the Keenan Wind Farm, and was developed by CPV Keenan Renewable Energy Company, LLC before being sold to Oklahoma Gas and Electric. Tetra Tech completed a Critical Issues Analysis, conducted various environmental studies, and developed a cost-saving design for the project. Subsequently, we were awarded the EPC contract. Construction on the project began in April 2009 and was completed on schedule in December 2009. The OU Spirit Wind Farm is generating enough electricity for approximately 25,000 homes since it was commissioned in early 2010. The project represents Tetra Tech's successful integration of our well-established environmental consulting and permitting support with our in-house engineering and wind construction services.

Final ACMP consistency determination was issued in November 2007. Alaska has since withdrawn from the National Coastal Management Program under the Coastal Zone Management Act, and Alaska no longer operates an ACMP as of July 1, 2011. State of Alaska Land Lease Agreement DNR Division of Land, Mining, and Water The three wind turbine sites are located on land owned by the State of Alaska. A land lease agreement is required to occupy State land. The preliminary decision on the land lease was issued in February 2009, and final decision was issued in May 2010. KEA continues to operate under an Early Entry Authorization during the land valuation process, which is expected to take an additional 3-5 years. City of Kodiak Land Lease Agreement City of Kodiak Road access to Pillar Mountain is through land owned by the City of Kodiak. City of Kodiak Ordinance 1237 dated June 2008, and a subsequent long-term lease agreement issued in October 2008 authorizes KEA to conduct activities related to wind projects on Pillar Mountain. Zoning Compliance Building Permit Kodiak Island Borough (KIB) Construction activities must be approved by the KIB to determine consistency with all applicable community development policies. A Conditional Use Permit was issued by the KIB Planning and Zoning Commission in October 2007, and the KIB Zoning Compliance Permit was issued in April 2008 for all six of the potential wind turbine sites on Pillar Mountain. A KIB Building Permit and Certificate of Occupancy will be acquired prior to construction of the Pillar Mountain High Penetration Wind Project sites. Pillar Mountain High Penetration Wind Project Summary of Permits and Regulatory Approvals 2Permit/Regulation Agency Purpose of Permit Permitting Status Determination of No Hazard to Air Navigation Federal Aviation Administration (FAA) This determination is required for construction of wind turbines and use of construction cranes. FAA conducts aeronautical study to determine if project presents hazard to the nearby airport. Determinations were initially issued in 2007 for all six of the potential wind turbine sites on Pillar Mountain. The determinations for the three Pillar Mountain High Penetration Wind Project turbine sites expired in February 2009. New determination will be required for these turbine sites a year prior to construction. KEA’s request for these determinations was filed on July 22, 2011. Bald and Golden Eagle Protection Act Migratory Bird Treaty Act of 1918 United States Fish and Wildlife Service (USFWS) These laws provide for the protection of the bald eagle, golden eagle and listed migratory birds by prohibiting the taking or possession of and commerce in these listed birds, with limited exceptions. Informal agency consultation was conducted in Anchorage in 2006. A year-long avian use survey was completed in June 2007. Avian use report was submitted to USFWS and Alaska DNR in October 2007. Post-construction raptor use surveys were conducted from July 2009 through the spring 2010 to document any interactions (or lack thereof) of the birds with the initial three wind turbines on Pillar Mountain. The results of this 2010 survey showed that bald eagles were avoiding the turbines. Avian use activity near the Pillar Mountain High Penetration Wind Project turbine sites will also be recorded. No additional permits are required. Section 402 of the Clean Water Act (CWA) Alaska’s Department of Environmental Conservation (ADEC) Division of Water Construction projects that disturb > 1 acre of land are required to develop a Stormwater Pollution Prevention Plan (SWPPP) as per the 2011 Alaska General Construction Permit (2011 AGCP). The SWPPP explains how runoff from the construction site will be properly managed. KEA is currently examining the recently issued 2011 AGCP and developing a site-specific SWPPP. A Notice of Intent (NOI) will be filed prior to start of construction of roadway access and Pillar Mountain High Penetration Wind Project turbine pad sites. Pillar Mountain High Penetration Wind Project Summary of Permits and Regulatory Approvals 3Permit/Regulation Agency Purpose of Permit Permitting Status Section 404 of the CWA United States Army Corps of Engineers (USACE) The discharge of dredge or fill material into waters of the US, including adjacent wetlands, requires a permit. This wetland permit application specifies erosion and sediment control measures. Wetland assessment report was completed in July 2006 and submitted to USACE in March 2007. The 404 CWA permit authorization under Nationwide Permit No. 18 for Minor Discharges was issued in July 2007, and was renewed in August 2009 and again in June 2011 to provide continual authorization for construction of the Pillar Mountain High Penetration Wind Project. Port of Entry Permit United States Coast Guard (USCG) The Port of Entry Permit coordinates access to the Woman’s Bay port. The barge delivery of the wind turbine components will be a domestic shipment and therefore did not require a Port of Entry permit. Navigation into Woman’s Bay was coordinated with through verbal communication. Oversize & Overweight Permit Alaska Dept. of Transportation & Public Facilities (ADOT) Division of Measurement Standards and Commercial Vehicle Enforcement Oversize & Overweight Permit required by ADOT to transport materials on state roads and highways. Fees assessed based on size and weight load. Oversize & Overweight Permits were issued in June 2009 for transporting the KEA’s other wind turbines from the barge dock to the Pillar Mountain site. Similar permits would be required for the transport of Pillar Mountain High Penetration Wind Project’s turbine components prior to construction. It is the construction contractor’s responsibility to acquire these permits. Supplemental Notice of Construction 7460-2 Part II FAA This notice of actual construction provides the information necessary for FAA to update their aeronautical charts with the new turbine structures. It must be submitted within 5 days of turbine erection. Notices for the Pillar Mountain High Penetration Wind Project turbines will be submitted within 5 days of turbine erection. Pillar Mountain High Penetration Wind Project Summary of Permits and Regulatory Approvals 4Permit/Regulation Agency Purpose of Permit Permitting Status Antenna Structure Registration Federal Communications Commission (FCC) Antennal structures that transmit a signal must be registered with the FCC. Registration with the FCC is not required because the wind turbines do not transmit a signal; they communicate via fiber optics only. Further, a microwave path obstruction analysis conducted in 2007 confirmed that the wind turbines would have no impact on FCC-regulated ration systems.
