Attached is a synopsis of the qualifications of the key staff and a listing of key consultants. This experienced engineering and management team operates and maintains two FERC licensed hydroelectric projects: Green Lake at 18 MW, Blue Lake at 8 MW. This team performed all the work necessary to obtain a new FERC license for the Blue Lake Hydroelectric Project. That thirty year FERC license was issued in March, 2008. Work is currently in progress by this team to amend the FERC license on the Blue Lake Hydroelectric Project to increase that project from 8 MW to 18 MW and increase its average energy generation capability by 35,000 MWH per year. 3.2 Project Schedule Include a schedule for the proposed work that will be funded by this grant. (You may include a chart or table attachment with a summary of dates below.) 2008: Obtain a FERC Preliminary Permit for the Takatz Lake Hydroelectric Project. 2009: Research history and prior investigations of Takatz Lake Hydroelectric Potential. Prepare Initial Consultation Document per FERC requirements. Consult with state and federal resource agencies, develop study plans. Consult with Alaska DOT on possible joint power/transportation project (transmission line with railway/lughway across Baranof Island) Conduct public meeting to hear public's concerns. Obtain the necessary permits for these studies, such as with the Forest Service. Install stream gages 2010 Conduct environmental studies Conduct geotechnical investigations Begin preliminary design work. Obtain aerial photography and prepare project maps. 2011 Complete the preliminary engineering and environmental studies. Prepare cost estimates. Prepare feasibility study and develop recommendations.

Publish the final feasibility report in 2011. 3.4 Project Resources Describe the personnel, contractors, equipment, and services you will use to accomplish the project. Include any partnerships or commitments with other entries you have or anticipate will be needed to complete your protect. 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. This is a study project, not construction. See 3.1 for project team and attached statement of qualifications. 3.5 Project Communications Discuss how you plan to monitor the project and keep the Authority informed of the status The Authority and FERC will receive semi-annual progress reports on the work accomplished and updated plans. See the attached FERC Preliminary Permit for FERC's reporting requirements. 3.6 Project Risk Discuss potential problems and how you would address them We expect some public controversy about construction in pristine areas. A significant reduction of risk could occur if the development of a power transmission line across Baranof Island is done in conjunction with a transportation project linking Sitka to Baranof Warm Springs via an electrified railway and/or highway through the Baranof River and Medvejie River valleys. The Alaska DOT has studied this transportation corridor and is interested in considering such a joint project. One of the major transportation issues is ventilating the railway/highway tunnel, which requires electric energy that could be supplied via the transmission line. Likewise, an electrified railway would be possible with power supplied via the transmission line. Public meetings will be held to hear and respond to public concerns about the project and the impacts on the community and the environment. AEA 09-004 Grant Application Page 6 of 18 9/3/2008 ALASKA Renewable Energy Fund it ENERGY WTHORM Grant Application SECTION 4 — PROJECT DESCRIPTION AND TASKS • Tell us what the project is and hove you will meet the requirements outlined in Section 2 of the RFA. The level of information will vary according to ,chase of the project you propose to undertake with grant funds i + If you are applying for grant funding for more than one phase of a project provide a plan and grant budget 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 See the attached preliminary permit application to FERC on the Takatz Lake Hydroelectric Project. Alternatives to developing Sitka's hydroelectric resources include wind, ocean, and geothermal. Sitka is rated as a class 1 wind regime, very poor for wind power. Prior wind energy prospecting by Sealaska in 2002 thru 2005 at Yakutat and Hoonah found average wind speeds of 9 mph and 10% capacity factors which rendered wind uneconomic. If a wind resource exists in Sitka it would likely be offshore or atop the mountains near Sitka, but there is no access and the cost of construction per kilowatt of capacity would be higher than hydroelectric and the service life of a wind turbine is only twenty years compared to one hundred years for a hydroelectric turbine. The geothermal potential is unknown as no exploration for geothermal reservoirs has been conducted on Baranof Island. Ocean energy generation technology (wave, tidal etc.) is in its infancy and not yet commercial. The best alterative for Sitka's long term power supply is its known and very reliable hydroelectric energy resources. This study project to determine the feasibility of the Takatz Lake Hydroelectric Project is the continuation of over one hundred years of hydroelectric power supply planning for Sitka dating back to early 1900's. The more recent engineering investigations over the decades resulted in the construction of the Blue Lake Hydroelectric Project in 1960, followed by the construction of the Green Lake Hydroelectric Project in 1982, the addition of two small hydroelectric units at the existing Blue Lake hydroelectric project in 1992, and now the expansion of the existing Blue Lake Hydroelectric Project to its maximum capacity which is expected to be completed and in service by 2015. We believe we are now entering an era of increasingly scarce and increasingly expensive oil which will result in sustained growth in the demand for lower cost alternatives, such as hydroelectric energy. See the attached Sitka Load Forecast dated September 12, 2008 and the chart of Sitka's energy requirements versus resources based on data from the load forecast. The forecasted demand for clean, renewable and relatively low cost hydroelectric energy to displace heating oil and gasoline could be as high as 223,979 MWH in 2029 (high forecast with electric cars, 171,419 MWH firm energy requirement plus 52,560 MWH interruptible energy sales) which would exceed the average hydroelectric generation capability of 159,000 MWH without Takatz Lake by 65,879 MWH. 65,879 MWH represents about a 60% utilization of the Lake Takatz Project's average 106,900 MWH capability in 2029. AEA 09-004 Grant Application Page 7 of 18 9/3/2008 f ALAS Renewable Energy Fund � ENERcrAUTHOF iTY Grant Application The most comprehensive work done on the Takatz Lake hydroelectric potential was by the Alaska Power Administration, U.S. Department of the Interior, in 1967. The plan of development dated January, 1968 is a result of a comprehensive investigation of Sitka area power alternatives by the USGS and APA over the period 1947 to 1967. ine estimated 27.7 Ii/I�1� capacity and 106,900 MWH average generation capability of Takatz Lake is from a 1974 Power Supply Study prepared for Sitka by R.W. Beck and Associates, Consulting Engineers. That R.W. Beck study, prompted by the USA oil crisis of 1973, recommended that the Green Lake hydroelectric potential be developed and subsequently the Green Lake Hydroelectric Project was constructed by the City of Sitka, corning on line in 1982. Under the planned study project, this prior body of work on the Takatz Lake hydroelectric potential will be reviewed and brought current with an examination of today's environmental, cultural, engineering and feasibility issues. The economic analysis will be developed in the feasibility study to be conducted as a primary product of this effort. Task List, Takatz Feasibility Studies Task 1. Team Orientation, Site Visit. Engineering/licensing/City team meets in Sitka to visit Project site, review existing information, develop Project plan. Task 2. Data And Information Gathering. Assemble available studies, hydrological data, topographic and mapping data on Takatz Lake, install steam gages and conduct further mapping work, including LMAR and GIS work, as necessary. Task 3. Conceptual Design, Initial Consultation. Engineers prepare conceptual design for use in Initial Consultation Document for Stakeholder review. Environmental/Licensing team and engineers conduct Initial Consultation meeting, take comment on early design and alternatives, develop preliminary resource issues list. Task 4. Environmental Study Planning And Execution. Environmental team members consult with the state and federal resource agencies on studies for fish, wildlife, cultural resources, recreation, water use and quality, etc., and prepare draft and final study plans. Task 5. Engineering Preliminary Design And Cost Estimation. Engineers advance design of preferred alternative, develop preferred operation mode. Prepare refined construction schedule and cost estimate. Task 6. Design, Operation Selection, Resource Negotiations. Engineers refine project configuration/operation proposals, team conducts preliminary negotiations on construction/operations conditions. Task 7. Feasibility Reporting. Team selects preferred alternative, incorporating resource conditions, and prepares feasibility report for use in application phase of FERC licensing. 4.2 Existing Energy System AEA 09-004 Grant Application Page 8 of 18 9/3/2008 E ALASKA Renewable Energy Fund uL EueRcvaunHorcrr Grant Application 4.2.1 Basic configuration of Existing Energy System Bnefly discuss the basic configuration of the existing energy system Incfude information about the number size, age. efficiency, and type of generation, Sitka's existing power plants are: Blue Lake, hydro 8 megawatts 63,000 megawatt -hours —1960 vintage Green Lake, hydro 18 megawatts 61,000 megawatt -hours - 1982 vintage Jarvis Street, diesel 12 megawatts Supplemental/Stand-by as required Total 38 megawatts 124,000 megawatt -hours hydroelectric 4.2.2 Existing Energy Resources Used Briefly discuss your; understanding of the existing energy resources. inblude a brief discussion of any impgct the pEoject may have on existing energy 'infrastructure and resources In fiscal year 2008, Sitka's total gross generation was 115,803 MWH. The net energy delivered to the Power Transmission and Distribution System was 114,128 MWH. Consumers are reacting to the rapid run-up in heating oil prices by shifting from oil to electric space heat. Sitka's average hydroelectric generation capability is currently estimated at 124,000 MWH and will typically range from 110,000 MWH in a dry year to 134,000 MWH in a wet year. As a result, considering a low rainfall year capability of about 110,000 MWH, Sitka has now used up its firm hydroelectric energy supply and the growth in load will be increasingly met with supplemental diesel generation until additional hydroelectric capability can be brought on line. 4.2.3 Existing Energy Market Discuss existing energy use and its market. Discuss impacts your project may have on energy customers See the attached Sitka Electric System Load Forecast, dated September 12, 2008 and the attached graph of Sitka's power requirements versus resources, 1973 to 2030. AEA 09-004 Grant Application Page 9 of 18 9/3/2008 ALASKA Renewable Energy Fund /,11wF M ENERGY WTHOWY Grant Application 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 spectfic to project location • Optimum installed capacity • Anticipated capacity factor • Anticipated annual generation • Anticipated barriers • Basic integration concept See attached application to FERC for a preliminary permit on Takatz Lake dated rune, 2008. 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 City & Borough of Sitka owns the shoreline lands around Takatz Lake and around Takatz Bay where the Takatz Lake Hydroelectric Project will be constructed. Access to the site is by seaplane or by boat from Chatham Strait. The transmission line route is mostly on federal lands managed by the U.S. Forest Service. The City & Borough of Sitka owns the shoreline lands along the east side of Silver Bay where this project's transmission line would interconnect with Sitka's existing 69 kV transmission system. The transmission line corridor on federal lands will be under FERC jurisdiction and will require a special use permit by the U.S.D.A. Forest Service. Access to the transmission line for constructon as well as maintenance will likely be over -land via a primitive equipment access road alongside the transmission line from the existing Sitka road system. 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 The primary authorization will be through a license issued by the Federal Energy Regulatory Commission (FERC), which will be lead agency for federally required environmental reporting and impact analysis under the National Environmental Policy Act (NEPA). The FERC license will contain Articles implementing terms and conditions from other resource agencies such as US Forest Service (USFS), US Fish and Wildlife Service (USFWS), Alaska Department of Fish and Game (ADF&G), Alaska Department of Natural Resources (ADNR), among others. Prior to construction, the City will require, among others, the following permits, certifications and authorizations: AEA 09-004 Grant Application Page 10 of 18 9/3/2008 �s ALASKA 4M ENERGYAUTHOMFY Renewable Energy Fund Grant Application • Special Use Permit, USFS; • Coastal Zone Consistency Determination, ADNR; • Title 41 Fish Habitat Permit, ADF&G; • Clean Water Act Section 404 Dredge and Fill Permit, US Army Corps of Engineers (USACOE); + State Water Right for Diversion and Impoundment of Water, ADNR; • Biological Assessment or Evaluation, USFWS; • Various fuel and hazardous substance spill avoidance, containment and cleanup plans, US Environmental Protection Agency, USACOE, Alaska Department of Environmental Conservation. Applications for these permits will occur at times specified by the respective agencies. USFS Special Use Permits may be necessary to conduct stream gaging, geotechnical, cultural resources and other surveys, beginning in 2009. Construction -related permits will be required before construction could commence. Licensing and permitting has been shown to be one of the most critical elements of hydro project development. The City team will work to address environmental conditions throughout the pre - construction period. This will involve negotiation of permit conditions well in advance of the construction start date to avoid adverse cost and schedule effects. Address whether the foliovAng environmental and land use issues apply, and if so how they will be addressed, • Threatened or Endangered species • Habitat issues • Wetlands and ether protected areas • Archaeological and historical resources • Land development constraints • Telecommunications interference • Aviation considerations • Visual, aesthetics impacts Identify and discuss other potential barriers Under FERC licensing regulations, environmental issues must be identified and addressed in the framework of a list of Stakeholders including state and federal resource agencies, interest groups, the public and affected tribes and Native Corporations. Issue identification, impact analysis and mitigation planning represent major components of a major project such as Takatz Lake. Through the required resource consultation process, the City will address environmental and land use issues including, but not limited to, the following: Fish and aquatic resources; Wildlife and botanical resources, including wetlands and sensitive plants; Water use and quality; Cultural resources; Recreation resources; Aesthetics; Threatened and endangered species; Subsistence resources; AEA 09-004 Grant Application Page 11 of 18 9/3/2008 ALAS KA Renewable Energy Fund LV ENERGY �tMORITY Grant Application Land use and ownership. Among potential barriers in the environmental area are FERC regulations which afford significant authority by the US Forest Service to condition any eventual FERC license. The City will work closely throughout the development process with USF S to develop conditions acceptable to USFS, the City and FERC. Resource specific issues will be identified during required consultation, early in the development process. Early identification allows prioritization of those issues most likely to affect development schedule, cost and ultimate project feasibility. Detailed schedules for and descriptions of the steps of the environmental process are in the attached Preliminary Permit Application. 4.4 Proposed New System Costs (Total Estimated Costs and proposed 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 Manufacturers estimates. 4.4.1 Project [development Cost Provide detailed project cost information based on your current knowledge and understanding of the project. Cast information should include the following • Total anticipated .project cost, and cast for this phase • Requested grant funding • Applicant matching funds — loans, capital contnbutions, in -kind • Identification of other funding sources • Projected capital cost of proposed renewable energy system • Protected development cost of proposed renewable energy system Sitka is engaged in a long range strategy to decrease its dependence on oil by developing its renewable energy resources, particularly the known hydroelectric resources on Baranof Island. This project is the study and investigation phase of developing Sitka's hydroelectric resources to determine the feasibility of developing the Takatz Lake Hydroelectric Project. The estimated cost of this study and investigation of the hydroelectric potential of Takatz Lake is $2,000,000. In addition Sitka has committed $4,764,937 of municipal funds in its FY2009 budget to developing its hydroelectric capacity at Blue Lake by expanding that existing hydroelectric project to its maximum capability. State funds of $12,500,000 have also been committed to the Blue Lake expansion. The expansion of the existing Blue Lake Hydroelectric Project to its maximum capacity is estimated to cost $50,000,000 in 2008 dollars, with a projected completion date of 2015. The grand total order of magnitude cost estimate for the Takatz Lake Hydroelectric Project is $225 million in 2008 dollars. The feasibility studies are estimated at $2,000,000. Final design and FERC licensing is estimated at $7,000,000. The cost of construction is estimated at $138,000,000 in 2008 dollars for the hydro project plus $78,000,000 for the associated transmission line across Baranof Island to interconnect with Sitka's existing transmission system in 2008 dollars. AEA 09-004 Grant Application Page 12 of 18 9/3/2008 fe: ALASKA Renewable Energy Fund r:r+EMr,wrHoWY Grant Application 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. • Total anticipated project cost for this phase • Leguested grant funding This project is a study project and does not incur O&M costs. The requested grant funding is $2,000,000. The estimated O&M costs of the completed Takatz Lake Hydroelectric Project will be developed in the study and assessment of feasibility. All of the costs to own, operate and maintain the Takatz Lake Hydroelectric Project will be paid for by the sale of electric energy. 4.4.3 Power Purchase/Sale The power purchase/sale information should include the following. • Identification of potential power buyers)/customer(s) • Potential power purchase/sales price - at a minimum indicate a price .range • Proposed rate of return from grant -funded project Sitka will be the owner and its residents the primary consumers, with surplus energy made available to other communities that may become electrically interconnected with Sitka. The principal market is the displacement of oil for Sitka's heating and ground transportation needs. Today's retail electric rates are approximately 40% lower than today's heating oil prices. If that relationship is maintained into the future the output of the Takatz Lake Project is expected to be fully utilized by Sitka to displace oil for heating and ground transportation needs. The expected Takatz Lake Hydroelectric power purchase/sales price at full utilization will likely be in the range of 10 to 20 cents per kilowatt-hour in 2008 dollars, depending on the cost of capital (mix of grant and bond financing). That compares to the current diesel generation purchase/sales price range of 50 to 60 cents per kilowatt-hour in 2008 dollars. 4.4.4 Cost Worksheet Complete the cost worksheet form which provides summary information that will be considered in evaluating the project. Download the form, complete it, and submit it as an attachment. Document any conditions or sources your numbers are based on here.

This study project to determine the feasibility of the Takatz Lake Hydroelectric Project is the continuation of several decades of power supply planning for Sitka dating back to 1924. The various engineering investigations over the decades resulted in the construction of the Blue Lake Hydroelectric Project in 1960, followed by the construction of the Green Lake Hydroelectric Project in 1982, the addition of two small hydroelectric units at the existing Blue Lake hydroelectric project in 1992, and now the expansion of the existing Blue Lake Hydroelectric Project to its maximum capacity which is expected to be completed and in service by 2015. We believe we are entering an era of increasingly scarce and increasingly expensive oil which will result in sustained growth in the demand for lower cost alternatives, such as hydroelectric energy. See the attached Sitka Load Forecast dated September 12, 2008 and the chart of Sitka's energy requirements versus resources based on data from the load forecast. The next hydroelectric project proposed for development is the 27.7 MW Takatz Lake Hydroelectric Project_ The most comprehensive work done on the Takatz Lake potential was by the Alaska Power Administration, U.S. Department of the Interior, in 1967. The plan of development dated January, 1968 is a result of a comprehensive investigation of Sitka area power alternatives by the USGS and APA over the period 1947 to 1967. Under the planned study project, this prior body of work will be reviewed and brought current with an examination of today's environmental, cultural, engineering and feasibility issues. The environmental issues, preliminary design and economic analysis will be developed in the feasibility study to be conducted as a primary product of this effort.

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 avoided cost of ownership) • Potential additional annual incentives (i a 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 This is a study project to determine the economic and public benefits as well as the feasibility of the Takatz Lake Hydroelectric Project. Sitka currently consumes about 6 million gallons of diesel fuel and 3 million gallons of gasoline per year, for a total of 9 million gallons for all purposes (power generation, heating, boats, vehicles). Currently, the retail electric rates are about 40% lower than the equivalent heating oil cost for space heating. The retail electric rates are about 80% lower than the equivalent gasoline cost in a passenger car. If these cost relationships continue into the future, and viable electric cars become commercially available, the potential is to displace most land based diesel fuel and gasoline consumption for heating and ground transportation in Sitka over the next twenty years. See the attached Sitka Load Forecast dated September 12, 2008. If half of today's diesel and gasoline consumption in Sitka were displaced by hydroelectric energy the potential fuel displacement would be about 4.5 million gallons per year. Displacing 4.5 million gallons of fuel per year represents an avoided fuel cost of about $22 million per year in 2008 dollars ($5 per gallon). The benefit to the enviromrnent of displacing 4.5 million gallons of fuel with clean, renewable hydroelectric energy would be a reduction in green house gas emissions of about 5 0,3 64 tons of carbon dioxide per year. Assuming the fuel is burned at an average efficiency of 50%, the equivalent hydroelectric energy required to displace 4.5 million gallons of fuel would be about 8 1, 000 MWH, which is 75% of the 106,900 MWH average capability of the Takatz Lake Hydroelectric Project, SECTION 6—GRANT BUDGET Tell us how much your total project costs.

June, 2008 EXHIBIT 1, DESCRIPTION OF THE PROJECT PROJECT FEATURES The project description and much basic data presented herein was obtained from a report by the U.S. Department of Interior, Alaska Power Administration (APA), entitled Takatz Creek Project — Alaska dated January, 1968. The City cites the proposed project design and other supporting data from that report in this application. In the following description, elevations are in feet above mean low sea level and are denoted " 09". General. The proposed project would be located about 21 airline miles east of the City of Sitka, Alaska on the eastern shore of Baranof Island. Development of hydroelectric power at the site would include construction of a lake tap, concrete dam, power intake, unlined tunnel, power penstock, power plant, tailrace, and transmission line segments (See Maps and written description below). Reservoir/Dam. Takatz Lake is located approximately 4,000 feet upstream of the mouth of Takatz Creek which flows into Chatham Strait by way of Takatz Bay on the eastern shore of Baranof Island. Normal water surface of the lake is at approximately El 840. Construction of a concrete arch dam approximately 200 feet high at the existing outlet of the lake would raise the lake level to El 1040. The reservoir would contain an active storage of volume of approximately 82,400 acre-feet. Lake Tap/Power Conduit. Water would be withdrawn through a lake tap into an approximately 2,800 foot -long, 6.5 foot by 7 foot modified horseshoe tunnel. The tunnel's downstream portal would connect to a 72-inch diameter, 1000 foot -long steel penstock leading to the powerhouse. Powerhouse, Switchyard and Tailrace. A surface powerhouse approximately 10,000 square feet in area would be constructed at ground level near Takatz Bay. The powerhouse would house two 18,600 hp Francis turbines, driving two 13.8 megawatt (MW) generators. A switch yard would be located near the Takatz Bay powerhouse and at the intersection with the existing transmission system near the existing Medvejie Fish Hatchery on Silver Bay. The powerhouse tailrace would provide an average of about 166 cubic feet per second (cfs) discharge into tidewater. Access Roads. Access for construction and long-term operation and maintenance of the Project would be via seaplane, helicopter and boat. An approximately 3-mile long gravel surfaced access and maintenance road would lead to Takatz Lake from a dock to be constructed on Takatz Bay. Transmission Facilities: Power generated by the Project would be transmitted by a new 26- mile long 138 kilovolt (kV) transmission line energized initially at 69 kV. The transmission line Preliminary Permit Application 4 Takatz Lake Project - Alaska City and Borough of Sitka Electric Dept. June, 2008 could consist of a combination of overhead, underground and submarine segments. Exact transmission type and routing will be determined based on further field investigations and feasibility studies. The line would interconnect with the existing 69 kV transmission system which currently connccts thc Biuc Lake and frccn Lake Projects to the City of Sitka lectric Department service area. The 138 kV transmission line insulation level would provide capacity for future power supply projects, including potential geothermal resources at Baranof Warm Springs and as many as five other potential hydroelectric project sites near Takatz Lake on the east side of Baranof Island. These other sites may be developed in the future as needs for additional renewable energy sources in Sitka increase. INSTALLED CAPACITY and ENERGY PRODUCTION Installed Capacity. Total installed capacity would be 27.7 MW, depending on final design. Annual Energy Production. The Takatz Lake project configuration evaluated in the 1968 APA feasibility study produced 97,100,000 kilowatt/hours (kWh) of firm annual energy and 9,800,000 kWh of non -firm energy for a total average capability of 106,900,000 kWh generation each year. The reservoir filled 14 years of the 19 year study, with spills occurring in 9 years. LANDS OF THE U.S. GOVERNMENT and of the CITY AND BOROUGH OF SITKA The project would be located within the Tongass National Forest on lands managed by the US Department of Agriculture Forest Service (USFS). The City and Borough of Sitka owns the shoreline lands of Takatz Lake and Takatz Bay. The transmission line would traverse Baranof Island on Federal lands managed by the USFS. The project would not use any Federal facilities. The Sitka Tribe of Alaska may be interested in the project. Preliminary Permit Application 5 Takatz Lake Project - Alaska City and Borough of Sitka Electric Dept. June, 2008 EXHIBIT 2, DESCRIPTION OF STUDIES TO DETERMINE THE FEASIBILITY OF THE PROJECT The Applicant proposes to conduct several studies to determine Project feasibility and environmental effects. The exact extent and nature of these studies will be determined during early stage consultation with Alaska state and Federal resource agencies, and results of more detailed engineering calculations. ECONOMIC and ENGINEERING FEASIBILITY EVALUATION Hydrology Stream flow records for 15 complete water years are available at a point on Takatz Creek downstream of the dam site with a drainage area of 17.5 square miles. The stream gage would be re-established to continue gathering stream flow data. Generation A generation study will be performed to determine the exact size and type of turbine/generator, switchgear, transmissions facilities and other electrical equipment. Engineering Feasibility Engineering feasibility studies will be performed in association with field surveys and topographic mapping to determine the constructability of the various project features in relation to surface and subsurface conditions, vegetation and topography. ENVIRONMENTAL and GEOTECHNICAL STUDIES Environmental Studies The exact nature and scale of environmental studies will be determined during agency consultation and study planning. Generally, however, environmental studies are required to meet information needs in the following areas: • Aquatic Resources • Terrestrial Resources • Water Use and Quality • Geology and Soils • Socioeconomics • Cultural Resources • Land Use and Recreation • Aesthetics Preliminary Permit Application ( Takatz Lake Project -Alaska City and Borough of Sitka Electric Dept. June, 2008 Geotechnical, Seismic and other Subsurface Investigations The 1968 APA report documented the geology at the site and concluded that conditions were adequate for construction of a concrete arch dam. The City will evaluate the need for additional geotechnical studies. NEW ROADS for CONDUCTING STUDIES No new roads are planned for conducting general environmental and engineering studies. Access by road may be necessary if additional geotechnical work is done. WORK PLAN FOR NEW DAM CONSTRUCTION Work for the proposed dam would occur over a three to four year period, including mobilization and demobilization. Work would be concentrated during the spring, summer and fall to minimize problems associated with winter weather and potentially deep snowfall. DISTURBANCES FROM CONDUCTING STUDIES Disturbances from conducting studies would be minimal. The only expected disturbance could arise if extensive additional geotechnical work were required, but previous studies in this area should preclude such a need. Any onsite work will be coordinated with the USFS, including obtaining a USFS Special Use Permit, if applicable. SCHEDULE FOR STUDY COMPLETION Engineering and environmental studies will be completed as necessary prior to expiration of the Preliminary Permit. Some environmental studies may continue through the post -application period and even during the construction period to satisfy requirements for environmental monitoring. EXHIBIT 3, ESTIMATED COSTS AND FINANCING ENGINEERING AND ENVIRONMENTAL STUDIES AND CONSULTATION COSTS Engineering and Economic Evaluation Costs. Based on review of existing information and data, and on our experience with other such evaluations in Alaska, we expect total Engineering and Economics studies to cost between $6,000,000 and $10,000,000 from inception through the final design stage. Environmental Consultation and Studies Costs. The Applicant, based on prior experience with remote project studies and construction, expects environmental consultation and studies to cost between $1,000,000 to $1,500,000, or higher, depending upon study requests from state and federal agencies and the FERC. Preliminary Permit Application 7 Takatz Lake Project - Alaska City and Borough of Sitka Electric Dept. June, 2008 FINANCING Financing is expected to come from a mix of sources, including municipal investments, State of Alaska energy development monies, federal funds, and bank financing. The exact mix of financing will be determined as the licensing proceeds. MARKET FOR POWER GENERATED Proposed Power Purchaser(s). Power purchasers would initially be electric utility customers of the City and Borough of Sitka. Over time, with increasing costs of petroleum -based fuel, demand for hydroelectric energy is expected to increase throughout Southeast Alaska. If electrical intertie facilities within the Southeast Alaska region become available, the Takatz Lake Project could help to meet renewable energy needs throughout the region. USE OF ENERGY BY THE APPLICANT The Applicant operates the power generation, transmission and distribution systems to provide electrical service to the community of Sitka, approximately 5000 consumers (meters), in the City of Borough of Sitka.

Historical and Projected Total Energy Requirements(1973-2028)......................12 Page i City and Borough of Sitka 2008 Electric System Load Forecast Report Introduction and Overview A 20-year annual forecast of electric customers, energy requirements and system peak demand has been developed for the City and Borough of Sitka (City) Electric Department. Although the 2008 forecast uses a similar approach to that used for the City's 2005 load forecast, a significant adjustment has been made in the new forecast to acknowledge the expected conversion to electric space heat in the community as a result of very high fuel oil prices. In addition, it is expected that in a few years there could be a number of electric vehicles operating in Sitka. As a result, an alternative high load growth case was developed that includes the energy requirements for electric vehicles. The number of customers and total energy sales have been forecasted for each of the City's customer classifications on an annual basis for the period 2009 through 2029.1 Four alternative growth scenarios: medium, high, low, and high electric vehicle were developed. A forecast of the energy requirements for the largest power users has been developed based on input from the City. In addition, a forecast of interruptible energy sales has also been developed that is based on the projected availability of surplus hydroelectric generation. It is important to note that the forecast has not been adjusted to reflect the potential increase in the cost of electricity that may be needed if power requirements exceed the hydroelectric energy generation capability of the City's system and more diesel generation is needed. With more diesel generation on a regular basis, the cost of electricity to consumers would potentially be higher than it presently is and demand could drop somewhat. The Electric Department has indicated that it intends to use the forecast to determine when additional hydroelectric capability should be developed. As such, the forecast provides a projection of total power requirements that could be expected if electricity prices remain in the same range as they are today. Since the City's last load forecast in 2005, total annual energy sales and energy requirements have increased every year. The total number of electric accounts has increased from 5,034 in 2005 to 5,180 in 2008, representing an average annual increase of 1.0%. Annual energy consumption per customer has increased since 2005 for residential and commercial customer classifications. It is believed that the increase in electricity consumption per customer is due to an increase in the use of electric space heat. In the year ended June 30, 2008, the City's total energy requirements were 112,772 MWh, an increase of 1.3% over the requirements in 2007. Following the closure of the Alaska Pulp 1 All references to annual totals are for years ending June 30, based on the City's fiscal year. Page 1 City and Borough of Sitka 2008 Electric System Load Forecast Company (APC) mill in 1993, total energy requirements decreased somewhat and remained relatively constant between 1994 and 2001 at which time they began to increase. Annual peak demand also dropped after 1993 and remained relatively constant between 1998 and 2003 at approximately 17.5 MW. Beginning in 2004 the peak demand began to increase annually reaching a record high 22.24 MW in 20082. Prior to 2008, the all time annual system peals demand was 22.0 MW in 1993 attributed, in part, to the partial requirements demand of APC on the City system. The 2008 forecast has been developed using an energy demand model that independently projects customers and energy consumption for each of the City's electric customer classifications for each year of a 20-year forecast period, 2009 through 2028. Although relationships between the number of customers and several variables were considered, the most significant correlations were established with population and the previous year's number of customers. Similarly, the number of commercial and public authority customers appears to be closely related to the number of residential customers when compared to the other variables evaluated. Energy use per residential customer has increased steadily since 2003, due most likely to an increase in electric space heat as fuel oil prices have continued to increase. Between 1993 and 2003, electric energy use per customer dropped each year. An increase in the price of electricity to consumers in 1993 is considered to have contributed to a price -induced reduction in electricity consumption. Prior to 1993, residential energy consumption per customer increased steadily over a 20-year period. Average annual energy consumption per Boat customer account has continued to increase year after year as more shore power is used by moored boats for heat and other purposes. Average energy consumption per commercial account has remained relatively constant in recent years but increased noticeably in 2008. Public Authority customers have also shown an increase in consumption in the past two years. Prior to the recent increase, the average energy consumption per Public Authority account remained relatively constant. Total energy sales by customer class for the years 1973 through 2008 are shown in Figure 1. As can be seen in Figure 1, a significant amount of energy was sold to APC between 1982 and 1990. The number of customer accounts and energy consumption per customer for the period 1973 through 2008 are shown in Table 7. Historical annual energy sales by customer classification, total system energy requirements and annual energy losses for the same period are shown in Table 8. Table 8A shows peak demand, average annual demand and annual loadfactors for the City's electric system for the same period. All three of these tables are located following the text of this report. ' The peak demand in 2008 occurred with an outdoor temperature of 6 degrees Fahrenheit.

Population projections for the City and Borough are periodically developed by the State of Alaska. Department of Labor (DOL). DOL's last detailed long-term projection was prepared in 2007 and the results were presented in the report, Alaska Population Projections: 2007-2030. This latest DOL forecast projects the total state population to increase at an average annual basis of 0.9% for the middle scenario. The low and high scenarios indicate average annual population growth of 0.4% and 1.5%, respectively. The 2007 DOL population projections indicate some minimal growth in the population of the City and Borough between 2007 and 2010 but show a gradual decrease in the City and Borough population over the ensuing 20 year period 2010-2030. In the 2007 DOL projection, the 2006 population was indicated to be 8,833 for the City and Borough. This value is somewhat lower than the reported population estimate of 8,989 provided in DOL's repor l on actual population characteristics. Further the actual population in Sitka was indicated by DOL to have actually declined by 349 to 8,640 in 2007 as a result of the closure of the Sheldon Jackson College. 3 Characteristics Of Boroughs And Census Areas And Components Of Change By Region, 1970-2007, Alaska Department of Labor and Workforce Development, Research and Analysis Department, Demographics Unit.. Page 3 City and Borough of Sitka 2008 Electric System Load Forecast DOL's population characteristics are noted as estimates4 based on a number of factors and it can't be verified through other sources yet as to whether or not this reduction in Sitka population has actually occurred. In 1993, the population of Sitka was nearly 9,000. Following closure of the pulp mill, the population declined to approximately 8,700 in 1997 before stabilizing and beginning a slight increase. Between 1997 and 2006, the population increased at an average annual rate of approximately 0.4%. Over the 25 year period, 1981 to 2006, the City's population increased by 1,006, representing a 12.6% overall increase and 0.48% average annual growth. For the purpose of the electric load forecast it has been necessary to develop a population projection to serve as the basis for the number of future electric consumers in Sitka. Based on the DOL forecast it has been assumed that the City and Borough population will increase slightly in the near -term but will then decrease gradually resulting in an average annual population change of -0.12% through 2030. This results in an overall population decrease of 211 by 2030 representing a total decrease of 2.3% over the estimated 2006 population. Alternative average annual population growth rates of -0.36% and 0.50% have been assumed for the low and high scenarios, respectively. The population projections used in the forecast are presented in Table 1 and Figure 2, below. Historical population from 1981 to 2007 is also shown in Figure 2. 4 The DOL estimated population numbers provide interim estimates of population between the federal census counts made every ten years. The next census will occur in 2010.

A regression analysis of the historical trend in the number of residential accounts indicates that the change from year to year is highly dependent on the previous year's number of accounts. This would mean that although the local population may change somewhat from year to year, the number of accounts served is more closely tied to the number of residences in Sitka. In other words, when the population decreases the number of persons per household drops slightly but the number of active residential electric accounts remains very similar. Long-term permanent trends in population due to major changes in the economy may show different results. The number of electric commercial accounts served by the City has historically been related to the number of residential accounts. Between 2005 and 2008, there were approximately 5.8 residential accounts per commercial account. The forecast of commercial, public authority and boats customer accounts has been developed as a function of residential customers. Forecasted number of customer accounts, by customer classification are shown in Table 9 for the medium, high and low growth scenarios. Since the number of residential customers is projected relative to forecasted population and recent trends in the number of customers served, there is a projected decrease in the number of customers served for the low growth scenario and a slight increase for the medium and high growth scenario. The projected number of customers for the medium scenario are summarized in Table 2. As can be seen in Table 2, the total number of customer accounts served by the City is projected to increase at an average annual rate of 0.6% per year. A more detailed presentation of the number of customer accounts is shown in Table 9.

Page 6 City and Borough of Sitka 2008 Electric System Load Forecast Energy Consumption per Customer Establishing a good relationship between energy consumption and variables such as weather conditions, per capita income, inflation and others, was not possible. Energy consumption is most likely affected by these variables, but based on the City's experience in recent years, no consistent relationship can be determined. For purposes of the forecast, energy consumption per customer has been assumed to be based on an average of consumption in recent years with assumed explicit changes applied, primarily related to assumed increases in the amount of electric space heat. Following completion of the Green Lake hydroelectric project in the mid- 1980's and until the early 1990's, new residential construction in Sitka often employed electric space heating. Some of this electric space heating was supplanted with fuel -oil based Monitor type stoves, which is reflected in the significant reduction in per customer residential electric energy consumption since 1993. With the current high price of fuel oil, the potential exists for a return to the use of electricity for space heating and a corresponding increase in overall electric energy use. The relatively high increase in energy consumption per residential customer the past two years would indicate that more electric space heat is being used in Sitka than was used prior to 2007. In all three load forecast scenarios, it has been assumed that a fairly significant number of residential customers will convert from oil to electric space heat. For some customers this conversion may entail replacement of the central heating system in the residence. In other cases it may be that portable electric heaters are used to supplement or replace space heating needs. At the present time, it is estimated that approximately one-third of the 3,620 residential customers in Sitka are currently using electric heat. For the medium load growth scenario, it is assumed that the saturation of residential electric heat customers will increase to about 50% over the next five years. For the high and low growth scenarios, the residential electric heat saturation is assumed to increase to 66% and 45%, respectively. Residential electric heat customers are assumed to require 1,700 kWh per month on average throughout the year compared to 700 kWh per month on average for non -electric heat customers. In addition to the medium, low and high load growth scenarios, a fourth forecast scenario has been developed to provide for electric loads related to electric vehicles. Automobile manufacturers have indicated that a greater emphasis will be placed on the development and marketing of electric vehicles. It is thought that with available hydroelectric power and a limited local road distances, Sitka may be a good community to employ electric vehicles as they become commercially available. For the electric vehicle scenario which is a modification of the high growth scenario, it is assumed that over an 18-year period, 75% of the passenger vehicles in Sitka will be electric. This transition is expected to occur gradually as existing vehicles wear out and are replaced. At the present time it is estimated that there are 4,860 passenger vehicles in Sitka. Electric vehicles are assumed to travel 4,380 miles per year at a rate of 5.0 miles per kWh. In addition, it is estimated that an electric vehicle will require 1,095 kWh per year for interior heating. Page 7 City and Borough of Sitka 2008 Electric System Load Forecast Base consumption amounts and assumed changes in consumption in the future are shown in Table 3. The energy consumption per customer for the commercial and public authority customer classes is adjusted net of the large customer loads discussed later in this report. Forecasted energy consumption per customer for each customer class through the forecast period is shown in Table 9. Details on electric space heat consumption are shown in Table 11 and assumptions related to electric vehicle loads are shown in Table 13.

Large Customer Loads The City has identified several large power loads based on energy consumption of about 100,000 kWh per month or higher. At the present time, there are twelve customers that meet this criteria, eight of which are commercial customers and four which are public authority customers. Energy sales reports prepared by the City include the large loads as commercial and public authority customers, respectively. Power sales have been forecasted separately for the large power users. The large power users include three large fish processors. The two well established processors pack a wide variety of seafood and use a large amount of electric power almost every month of Page 8 City and Borough of Sitka 2008 Electric System Load Forecast the year. The products are frozen and so the major load is refrigeration. In 2007 both plants upgraded refrigeration capacity to process pink and chum salmon in a whole body form. This was in response to the construction of a large processor at the Sawmill Cove Industrial Park which is designed to freeze whole salmon, herring, and roe. This new processor has very high use in late March and early April and high use during pink and chum salmon runs in the summer. All the processors indicate that large investments were made in 2007 which should carry them into the foreseeable future. The City Cold Storage Facility is fundamentally a large refrigerated box. Product is delivered already frozen and energy use is probably more related to outside temperature than to the amount of product handled. About three years ago outlets were added for several freezer vans and this would be reflected in the 2007 energy use. No expansion is planned and it is expected that energy use at this facility will remain constant in the future. In 2007, there was a record herring harvest but a greatly reduced salmon harvest. The long term outlook does not seem good for a sustained high level salmon harvest. For the processors in the medium and high growth scenarios, it has been assumed that electric loads in the future will remain the same as 2007. In the low case the processor energy use is assumed to drop 10% between 2008 and 2012, another 10% over 2013 to 2019, and another 10% out to 2029. Since maximum demand is based normally on total compressor capacity, it is not expected that demand will change unless a processor ceased to operate. The two large grocery stores in Sitka have performed lighting and refrigeration upgrades in the past few years and there is little reason to think these loads will change significantly even with moderate changes in population. As a result, it has been assumed that the grocery store loads will not change from 2007 levels. SEARHC, the Southeast Alaska Regional Health Consortium is the largest employer in Sitka with over 500 employees. SEARHC is the regional health care center primarily for native health care. It is relatively certain that this facility will continue to operate in the far future. Further, the hospital is being upgraded and some housing is being added to the site. It has been assumed for the medium and high cases that the hospital load remains unchanged and for the low case that some functions are exported to new village clinics and perhaps an outpatient facility in Juneau. Four public authority loads are among the large power consumers. These loads include the US Coast Guard and three facilities of the School District. The US Coast Guard ship Maple, the rescue helicopter base, administrative buildings and housing units would seem to be stable in size and energy use in the foreseeable future and it is assumed that no change will occur in the load for all growth scenarios. The School District has undergone upgrades over the last few years, including a new auditorium in 2007. Student population is declining slightly and no significant new construction is indicated. Schools, however, do not typically reduce electricity use with moderate decreases in enrollment. As a result, it has been assumed that the School District energy use will remain constant for all cases. Energy requirements of the large loads are shown in Table 14. Page 9 City and Borough of Sitka 2008 Electric System Load Forecast Total Energy Sales Based on the forecasted number of customers and the projected electricity use per customer account, total annual energy sales have been forecasted. The results of the forecast for each of the customer classes and for each year of the forecast period are shown in Table 10 and are summarized for selected years in Table 4. As can be seen in Table 4, total energy sales are forecasted to be 115,982 MWh in 2010 for the medium growth scenario. This amount is approximately 6,830 MWh more than was sold in 2008, representing an increase of 6.3%. Much of the increase between actual sales in 2008 and forecasted sales in 2010 is due to the assumption of fairly significant residential electric heat conversions because of high fuel prices. In addition, the increased power sales at the Sawmill Cove industrial site experienced in 2008 are assumed to continue in the future. Total electricity consumption at the Sawmill Cove industrial site (former site of the Alaska Pulp Company pulp mill) was approximately 4,190 MWh in 2008, up significantly over the previous year. Part of the increase is attributable to the summer processing load of Silver Bay Seafoods. This load is expected to continue at its present level. The load of Silver Bay Seafoods is included among the large customer loads described in the previous section of this report. For the purpose of the load forecast, it is assumed that the loads at Sawmill Cove will remain at about the level experienced in 2008 with a slight increase over time for the medium load growth scenario. Alternative high and low forecasts of the load are also included. The total estimated energy requirements at the Sawmill Cove site for each year of the forecast period are shown in Table 10 in the column labeled "SMC". As previously mentioned, the load of Silver Bay Seafoods, which is located at the Sawmill Cove Industrial Park, is included among the large customer loads.

Page 10 City and Borough of Sitka 2008 Electric System Load Forecast Total Energy Requirements The City's total energy requirements are the sum of total energy sales, interruptible energy sales and energy losses. Non -billed public authority use is approximately 2,200 X1Wh per year at the present time, however, for the most part this load is accounted for in the public authority customer classification. Interruptible energy sales were 852 NfWh in 2008, down significantly from 1,747 MWh in 2007. Interruptible energy sales are only made if surplus hydroelectric energy is available. It can be expected that interruptible sales will vary from year to year and will be under pressure to increase as a result of high fuel oil prices. . Energy losses experienced by the City in the years 2003 through 2008 have varied between 2.5% and 8.2% of total energy requirements, averaging 5.1 %. Prior to 2003, energy losses were typically in excess of 6.0% of total energy requirements. It is not known if the significant decrease noted in recent years is due to accounting changes or other factors. For the purpose of the load forecast, energy losses are assumed to be 5.5%, 6.5% and 5.0% of total energy requirements for the medium, high and low load growth scenarios. Forecasted total energy requirements are shown in Table 10 and are summarized in Table S. Historical and forecasted energy requirements are shown in Figure 3 with average annual growth rates over the periods 1973-2008 and 2008 2029 indicated also.

Prior to 1995, average annual load growth was significantly higher. The results of the forecast indicate average annual load growth over the next 20 years of 1.2% for the medium growth scenario, 1.9% average annual load growth for the high scenario, 0.5% average growth in loads for the low growth scenario and 2.1 % average annual load growth for the electric vehicle scenario. The 2008 Load Forecast indicates higher growth than was forecasted in the 2005 Load Forecast, 1.2% as compared to 0.8% average annual growth for the medium scenario. Most of the higher rate of load growth is attributable to the expected higher use of electric space heat in 5itka. Peak Demand Peak demand of the City's electric system has been forecasted based on the forecast of total energy requirements and an assumed annual load factor. The load factor is the ratio of peak demand to average demand. In recent years, the City's annual load factor has been relatively consistent at approximately 60%. For the purposes of the forecast, the annual load factor has been assumed to be 58% for the medium growth scenario, 60% for the low growth scenario and 52% for the high and electric heat scenarios. The forecasted peak demand for each year is shown in Table 10 for the four growth scenarios and is summarized in the following table.

The price of electricity sold through this program will be tied to the price of fuel oil in Sitka. At the present time, the City Electric Department has identified several interruptible energy customers, primarily schools and other municipal facilities that could potentially begin receiving interruptible service within the next several years. In total, it is estimated that these electric customers can use approximately 52,600 MWh per year of electric energy purchased under the interruptible energy program. Other municipal and commercial facilities have also been identified that could potentially purchase interruptible electric energy in the future. The amount of energy available to serve this interruptible load is dependent on the available hydroelectric generation in any given year. As with all hydroelectric systems, the City's generation potential varies from year to year depending on local precipitation. It is presently estimated that the average annual energy generation capability of the City's hydroelectric system is 124,000 MWh. This generation capability is estimated to vary between 85,000 MWh in extremely dry years to 135,000 MWh in very wet years. Further, the City has indicated that a third turbine could potentially be installed at the Blue Lake hydroelectric project that would produce about 16,000 MWh on an average annual basis. In extremely wet years, it is estimated that the third turbine could generate an additional 25,000 MWh whereas in dry years there would be no additional energy generation. Additional hydroelectric capacity is envisioned for the Page 13 City and Borough of Sitka 2008 Electric System Load Forecast future including 19,000 MWh per year from a further expansion of the Blue Lake project and 106,000 MWh per year from the Takatz Lake project that could be constructed as early as 2021. An estimate of potential interruptible energy sales has been developed based on the City's estimate of potential interruptible municipal and industrial loads and the estimated amount of hydroelectric generation surplus to the needs of the City's firm energy service customers. As the City's firm energy loads increase over time, the amount of surplus hydroelectric generation available for interruptible sales will decrease. Further, the amount of surplus hydroelectric generation available in any given year will vary significantly due to seasonal precipitation levels at the time. The estimated interruptible energy sales are shown in Table 12. In summary, interruptible energy sales with the existing installed hydroelectric capacity are estimated to be somewhat limited, ranging between zero in most low and average water years to as high as 12,600 NM in wet years. Under average water conditions with medium retail load growth and assuming the third turbine at Blue Lake is installed in 2015, interruptible energy sales are estimated to increase.

Sponsor: Administrator CITY AND BOROUGH OF SITKA RESOLUTION NO.2008-21 A RESOLUTION OF THE CITY AND BOROUGH OF SITKA, ALASKA AUTHORIZING A GRANT APPLICATION TO THE ALASKA RENEWABLE ENERGY FUND FOR DETERMINING THE FEASIBILITY OF THE TAKATZ LAKE HYDROELECTRIC PROJECT Whereas, we are entering an era of increasingly scarce and increasingly expensive oil over the next twenty years and beyond; and, Whereas, Sitka is heavily dependent on oil for heating and transportation; and, Whereas, due to high oil prices Sitka consumers are switching to the alternative of electric heating which has fully utilized Sitka's existing hydroelectric energy supply; and, Whereas, the long range electric load forecast is that Sitka consumers will continue to switch to electric energy for most of their heating and ground transportation needs; and, Whereas, to meet the growth in demand for electric energy Sitka is now developing the expansion of its existing Blue Lake Hydroelectric Project to its maximum capability, which could increase Sitka's hydroelectric energy supply by about 28%; and, Whereas, Baranof Island has substantial undeveloped hydroelectric potential; and Whereas, developing the hydroelectric potential of Takatz Lake could double Sitka's hydroelectric energy supply as well as facilitate the electrical interconnection of other communities in Southeast Alaska with Sitka for the mutually beneficial sharing of renewable energy resources to displace oil; and Whereas , Sitka has made application to the Federal Energy Regulatory Commission (FERC) for a preliminary permit to determine the feasibility of developing the hydroelectric potential of Takatz Lake and the associated electric transmission line across Baranof Island to connect to Sitka's existing electric transmission system. Now therefore be it resolved by the Assembly of the City and Borough of Sitka that Sitka is committed to reducing its dependence on oil and developing its renewable energy resources; and, Resolution 2008-21 Page 2 Be it further resolved that the Administrator is authorized to apply to the Alaska Renewable Energy Fund for $2,000,000 to conduct the environmental, cultural, engineering and economic studies necessary to determine the feasibility of developing the hydroelectric potential of Takatz Lake. Passed and approved by the Assembly of the City and Borough of Sitka, Alaska on this 23rd day of September, 2008. Marko Dapecevich, Mayor ATTES Colleen Pellett, MMC Municipal Clerk
