Refer to Section 1.5 of RFA. This is a community high penetration wind-diesel smart grid construction project. 2.2 PROJECT DESCRIPTION Provide a one paragraph description of your project. At a minimum include the project location, communities to be served, and who will be involved in the grant project. The work plan consists of the installation, control and integration of five major components: 1. Five Wind Matic 17-S Wind turbines on 80 foot lattice towers, 2. Diesel Station upgrade 3. Energy recovery boiler at the washeteria for frequency control 4. Smart metering system 5. 20 Thermal Stoves in residents of village elders The wind turbines will be installed 300 foot apart on pile foundations, and connected via individual three phase transformers to the existing power lines with buried armored cable. Connections between the turbines will be via buried armored cable. A fiber optic cable will be buried along side the power cable to provide a communications link with the powerplant. The US FWS has expressed and interest in keeping overhead transmission to a minimum, to reduce any potential hazards to passing migrating birds. The energy from the turbines will be integrated into the diesel power systems. Three methods will be used: 1. power electronics connected with a heat recovery boiler for frequency control 2. adaptations to diesel generators to enable low load operation 3. an integrated control system that operates both the wind turbine and diesel generators in a coordinated manner with ceramic thermal storage located in the residents of village elders. Two existing gensets will be modified to operate at low loads and low fuel consumption for extended periods of time. The main features of the conversion will consist of the addition of a boiler and boiler grid interface to provide reverse power protection to absorb wind gusts when operating at near zero kW, and to increase operating temperatures to eliminate cylinder glazing and wet stacking. The Smart Grid consists of a network of advanced meters, which receive information about the availability of green, or excess wind energy and make this energy available to the community at reduced rates, and enable devices to capture this energy. The meters communicate wirelessly, provide a user interface for customers, and account for energy sold at different rates. The meters can be programmed for prepayment. The Smart Grid enables 25 thermal storage Renewable Energy Fund Grant Application AEA 09-004 Grant Application Page 4 of 42 9/3/2008 devices that are located in the homes of 25 village elders, and these stoves capture and store excess wind energy for later use. The stoves will be installed in 1/3 of the homes in the community. The Smart Metering and the stoves create a system that allows wind energy to be sold as heat for ½ the cost of diesel heating. This is picture of the wind site in Kwigillingok.

These systems have included both wind generation and waste heat recovery systems. STG has installed 6, and is currently installing 3, wind generators and 10 waste heat recovery systems for Alaska Village Electric Cooperative. These wind generators, consisting of both AOC 15/50's and Northern Power's Northwind 100 wind turbines, are integrated with the onsite diesel generation systems. The waste heat recovery system captures the waste heat from the generators and also provides a dump load source for the wind generators during times of high winds and low village load demands. The recovered waste heat and excess wind energy is used to heat various Renewable Energy Fund Grant Application AEA 09-004 Grant Application Page 15 of 42 9/3/2008 facilities within the communities. Power Distribution STG has completed several power distribution projects in Western Alaska for Alaska Energy Authority, Alaska Village Electric Cooperative and United Utilities, Inc. The projects have consisted of both direct bury poles and poles installed on pile foundations. Terrain has varied from across tundra to mountainous steep slopes. Foundations STG has emerged as the prevalent pile foundation contractor in the Interior and Western Alaska. STG's experience includes installation of driven and drilled steel piles, thermopiles, helical anchors and piles, concrete foundations and rock anchors. STG has the specialized equipment necessary for installing foundations in extremely remote and logistically challenging locations. Renewable Energy Fund Grant Application AEA 09-004 Grant Application Page 16 of 42 9/3/2008 Civil Construction STG utilizes the newest, state-of-the-art, late-model equipment to execute civil construction. We have the ability to perform any concrete, demolition, earthwork, utilities, drilling/blasting and crushing/screening jobs. These projects are generally performed in conjunction with our other work. However, we have executed several "stand-alone" civil projects, as well. Power Plants Renewable Energy Fund Grant Application AEA 09-004 Grant Application Page 17 of 42 9/3/2008 STG has constructed over twenty diesel power generation facilities (power plants) throughout Western Alaska for both Alaska Energy Authority and Alaska Village Electric Cooperative. These power plants, which range in size from 100 to 1,500 kilowatts, generally consist of modular units with either gravel pad or pile foundations. List and Describe Briefly the Most Significant Projects Performed by the organization in the past for projects similar to that proposed. UUI DELTANET BROADBAND Phase 1 Completed 2006 (235’ Tower – Microwave Telecommunications) We made Agreements with United Utilities, Inc. (UUI) to install a three phase line to the wind farm site. Construction costs to the wind farm site will be shared by UUI and PPC. AEA-RPSU RURAL POWER SYSTEM UPGRADE Completed 2003 System online 4/05. (Heat Recovery to washeteria with the system) Note: Heat recovery to the nearby high school facility also possible. AEA- BF BULK FUEL CONSTRUCTION Completed 2001 Renewable Energy Fund Grant Application AEA 09-004 Grant Application Page 18 of 42 9/3/2008 3.5 Project Communications Discuss how you plan to monitor the project and keep the Authority informed of the status. Project budget and status reports Monthly status reports Web based monitoring 3.6 Project Risk Discuss potential problems and how you would address them. The control methods and system components selected for this project have been proven. The only product development work which needs to be completed is linking the supervisory controller signals to the metering system. This development is underway, and will accomplished either with and on-site server at each powerhouse, or through powerline carrier and mini- recievers through the powerplant supervisory controller. The primary project risk is in sorting out all the little problems that will occur after commissioning and through the break in and training period. A full time qualified project engineer will be assigned to the Chaninik Wind Group from January 2009 through June of 2010. The other issues that must be addressed is the use of available wind energy for home heating. The system now calls for rotation of meters on a first in first out basis, and a repriortizing of the availability of excess wind energy on a daily basis. 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 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 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. Kwigillingok is located 8 miles from the community of Kongiganak. One year of 30 meter onsite data was available and can be downloaded from the Alaska Energy Authority Website. The Kong site was selected by wind resource experts from the National Renewable Energy laboratory to provide a monitoring location which would provide regionally valuable data. The AEA website provides a complete wind resource assessment report. Renewable Energy Fund Grant Application AEA 09-004 Grant Application Page 19 of 42 9/3/2008 www.akenergyauthority.org/programwindresourcedata.html. The results of the wind resource evaluation indicate an outstanding wind resource with an average wind speed is 7.78 m/s, and with the power distribution well suited for the capture of wind energy. The AEA report gives an annual average temperature of 1.4°C, which at sea level corresponds to an air density of 1.286 kg/m³. The data was analyzed in the Homer model to and compared with the power curves of various candidate wind turbines. 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. A new diesel powerplant at Kwig came on line in the Fall of 2005. At that time an analysis was made of the plant fuel consumption to establish a usage base case and to estimate future loads. The electric load data is displayed in the tables below and the following figure provides a profile of the loads which were used for this analysis. The load above includes an expected 15% load increase due to the new school which will be completed in 2010.

This diagram, contains two future elements, the solar panels, and distributed residential energy storage. These two components are shown only to indicate the extent of the system potential. Renewable Energy Fund Grant Application AEA 09-004 Grant Application Page 24 of 42 9/3/2008 The project design offers a very simple and reliable wind diesel architecture, which will achieve 40% fuel saving at the electric utility, and 20% of the fuel requirements of the community. Wind Turbines: Two candidate wind turbines were primarily considered for this project, these are: The Northwind 100 and the Windmatic S-17. An analysis using both turbines was made for cost effectiveness. The comparative economic feasibility favors the use of multiple Windmatic turbines, primarily due to the additional expenses incurred to install the Northwind 100 in a warm permafrost area such as Kong. These turbines were selected for performance and availability. Three 17S Windmatic turbines have been purchased and have been shipped to the project site. Additional turbines could be purchased and delivered for construction this winter. Construction using the Northwind 100 would be delayed until winter construction season 2010. The 17S is available and parts and service are common, with most components available in Anchorage or Seattle. The Windmatic is available from Scientia Wind Services, Palm Desert California. Renewable Energy Fund Grant Application AEA 09-004 Grant Application Page 25 of 42 9/3/2008 Cost estimates for the installation of each turbine were developed after geotechnical investigations and load analysis, and are summarized in Table 3. Installation costs estimates were developed for both types of turbines. Gross annual estimated energy production for each turbine was arrived at through comparison of power curves and wind resource information using HOMER. The results are summarized in Table 4. A 15-year investment horizon and a 5% nominal interest rate were used for economic analysis. These are the same investment guidelines as proposed in the Alaska Rural Energy Plan, April 2004.

Blade extensions and taller towers can be used to increase the output of both wind turbines. The AEA report estimates NW100 number is 313 MWh, which is 10% higher than our number of 282 MWh. This is a conservative estimate for both turbines, and represents an accurate comparison. Five wind turbines with a rated output of 90 kilowatts for a total rated output of 450 kW, are paired with multiple diesel options of 235 which are able to parallel and operate at low load. The supervisory control system would operate the two gensets in frequency control modes, and the other two generator sets would remain in their original condition and operate in set point mode. In period of low winds the additional wind turbines would enable the utility to operate at high penetration levels, efficiently servicing the electrical load. As wind increases, which is frequently at night most of the winter, excess wind energy would be diverted to thermal stoves located in community facilities and residences. This excess wind or “ green” energy would be made available to customers at a reduced rate, however, since most of this energy would be created at night in the wintertime. Wind-diesel Integration The goal of this project is to provide a cost effective higher penetration system to significantly minimize diesel fuel usage. In all high penetration applications, close generation, load controls and the ability to stabilize the grid are key features. The controls must not only trigger diesel generators to start and stop, but must also issue power set points for each component in the Wind Turbine Annual Energy Production (kWh/yr) Capacity Factor (%) Hours of Operation (hrs/yr) Windmatic 17S - 90 kW 225,000 30.2 7,373 Northwind NW100/19 282,000 31.6 7,467 Renewable Energy Fund Grant Application AEA 09-004 Grant Application Page 26 of 42 9/3/2008 system and send enable/disable commands to the wind turbines as well as control any demand managed devices, such as the thermal stoves. In this application the output of the wind plant is at times oversized to the load. The excess power is sent over the electrical distribution system to select valuable but thermal storage devices which are interruptible loads. A fast acting Dynamic Grid Interface is connected to a boiler in the washeteria. This boiler is connected into the heat recovery system of the powerplant, and will be used to maintain all diesel generators in a hot and ready to operate setting. This boiler will be used to capture a limited amount of the excess wind energy and will be used as the primary energy sink to keep grid frequency from rising. The grid interface instantaneously absorbs power fluctuations caused changes in turbine output. When coupled to a low-load generator, which is able to operate efficiently at low loads for long periods of time, the Dynamic Grid Interface prevents the generator from being driven into reverse power and supplements reactive power support for the wind turbines. The power system is managed by a computerized supervisory controller, which monitors all system parameters and makes decisions based on sub-second time scales to regulate each component of the wind-diesel system. The supervisory controller tracks the wind and engine output along with load demand and upon meeting preset criteria for changing conditions, automatically carries out instructions with safety margins such as selecting, turning engines on/off, managing heat recovery loads, and shutting wind turbines on and off. When the wind power is insufficient, the supervisory controller selects and starts the most efficient engine or combination of engines, brings those engine(s) up to synchronous speed, and commands the wind turbines to turn off. To achieve significant fuel savings high penetration wind diesel systems must be able to operate indefinitely at instantaneous wind penetrations of greater than 100%. There are a number of configurations to high penetration wind diesel systems, which are not covered or compared in this study. However the keys to high penetration reliability remain the same: control of the diesel station, wind turbines and other components, and a method to stabilize the grid while reducing diesel loading.

GS Diesel Generator Wind Turbine All four (5) turbines are Windmatic s-17's Wind Turbine Wind Turbine Thermal Stoves Web access Smart Meter This design builds upon the capabilities of the existing power system by using power electronics and controls to prevent reverse power conditions and fouling conditions during extended low load operations. The ability to operate a low load, increases the instantaneous proportion of wind energy, while decreasing fuel usage. The remote heat recovery boiler will be placed at the washeteria, to recover excess wind energy, and smart meter enabled thermal energy storage units will be placed in community buildings and twenty residences. In this configuration, in low winds, the system will operate in a high penetration mode, with the available wind captured to displace fuel used to generate electricity. As wind speeds increase greater proportions of wind energy are captured as heat. Renewable Energy Fund Grant Application AEA 09-004 Grant Application Page 28 of 42 9/3/2008 Diesel Retrofit The main features of diesel operation include: precise fuel management, increased operating temperatures, special engine monitoring and control, and reverse power protection. This design proposes to adapt two of the existing gensets, one of the 190 kWe and one of the 225 kWe machines for low load operation to operate in load following frequency set point mode for parallel operation with the wind turbines. The control system and power electronics design would allow either generator to operate in low load, or for the two generators to operate in parallel low load. The low load units can also operate with the other non-modified gensets in power set point mode. Low Load Operation Under normal conditions, a diesel configured for low load behaves like any other diesel generator, with the added benefit of very high efficiency. In all situations, the existing diesel will operate in isochronous mode, attempting to maintain the nominal frequency of the network. During periods of low-load or high renewable penetration, the Station Controller can be programmed to allow the running low-load configured diesels to run down to 5% of their rated load. During low-load operation, especially with wind turbines, the diesels may be forced to use its dynamic inverter grid interface to prevent the generator from being pushed into reverse power operations. Control, fuel management, and injection of additional heat modifications are made so that normal point of operation can be maintained indefinitely, even with frequent operations of the grid interface and fluctuations in the wind plant output. Since the instantaneous total loss of power from multiple turbines is an unlikely event, the parallel operation of either low load diesel would survive (non-stalling) single step-load is larger than the loss of two turbines at full output, 130 kW or a similar increase in load from a 5% low operating threshold. Heat Recovery Boiler Grid Interface A remote heat recovery boiler with dynamic response capabilities will be placed at the school. The Boiler Grid Interface has three distinct roles: 1. To provide a demand managed device, capable of delivering heat to a heating loop in a complimentary manner to the availability of the wind energy. 2. To provide frequency stabilization through the high speed frequency monitoring and the rapid adjustment of load from the boiler grid interface. 3. To provide a fully adjustable load with small 100W steps and an adjustable power factor without inducing damaging harmonics into the power system. Operation The temperature controller in the Boiler Grid Interface device monitors the temperature of the loop and makes requests to the power station master controller for power to maintain the temperature. The power station master controller sends back a power set-point which the Boiler Grid Interface is to maintain long-term. This number is based on the amount of uncommitted wind power available on the system. If the frequency of the grid moves outside of acceptable limits, the Boiler Grid Interface will automatically adjust the amount of power it is drawing, based on a sliding linear scale in an Renewable Energy Fund Grant Application AEA 09-004 Grant Application Page 29 of 42 9/3/2008 attempt to maintain control over the frequency. Once the frequency is back within acceptable limits, the Boiler Grid Interface returns to its original power set-point. If the frequency does not return within acceptable limits over a period of approximately 2 seconds, the power station master controller will take additional action (such as modifying the power demand of the Boiler Grid Interface, starting additional generator sets or disconnecting Demand Managed Devices) to rectify the situation. Method of Power Control The Boiler Grid Interface uses IGBT technology to meet the following competing goals: 1. Fully adjustable 0-100% load control in steps of approximately 0.025% 2. Fast response time, 0-100% in less than 1/180th of a second. 3. Exceptional power quality, with the option to actively improve the voltage waveform at the expense of maximum load sizing. The IGBT based technology can offer such fast power control due to its ability to modify the current draw at any point in the cycle, whether it be mid-cycle or not. This feature also allows the IGBT based Boiler Grid Interface to draw current at a pre-specified power factor, to attempt to help the generators support any low power factor loads that may be encountered. This compares with standard SCR load control technology which offers: 1. Fully adjustable 0-100% load control. 2. Fast response time, 0-100% in 1/60th of a second or so, depending on control technique. 3. Poor power quality, introducing damaging harmonics into the power system. Renewable Energy Fund Grant Application AEA 09-004 Grant Application Page 30 of 42 9/3/2008 The Smart Grid The Smart grid is a way combining the various components of the power system to make them work efficiently together, and to support new services for customers. What is being proposed here is a simple form of the smart grid, in which the power plant supervisory controller that controls the diesel engines and the wind turbines communicates with the customer’s electric meter. The powerplant controller tells the electric meter that there is excess wind available for sale at a reduce price. The smart electric meter signals various devices, like thermal energy storage unit to turn on and store wind energy. When low cost wind energy is not available the meters turn off the heating elements in the stoves. The meters keep track of the two types of electricity, green only and diesel generated electricity, and provide an in home display so that customers can keep track of their costs and energy uses. The smarts of the smart grid are in the software and hardware of the utility meters, the powerplant supervisory controller, and the thermal stove controllers that allow the devices to intelligently communicate with each other. The result is a new way of managing rural energy systems, and the creation of new opportunities to expand the role of wind energy to reduces the dependency on diesel fuel. The next stage in implementing the Smart Grid will be to add plug in 4 wheelers for local use. The community will benefit from the Smart Grid in three ways: 1. Lower cost energy as heat and electricity 2. Increased revenues to the utility 3. Ability to store wind energy as heat for later use. Figure 4 depicts the elements of the Village Smart Grid: Renewable Energy Fund Grant Application AEA 09-004 Grant Application Page 31 of 42 9/3/2008 Electric Thermal Storage During a windy weeks in the winter a typical home in Kwig uses 30 gallons of heating fuel. The Electric Thermal Storage (ETS) is the method of capturing excess wind generated electricity as heat and storing it for use 24 hours a day. An ETS unit, is an insulated metal box, about the same size as a Toyo Stove, which contains electric heating elements which lie within special, high-density ceramic bricks. These bricks are capable of storing vast amounts of heat for extended periods of time. During periods of excess wind energy, a signal from the powerplant supervisory controller is sent to the metering system. The meters then enable the elements in the stoves to heat the bricks. The availability of wind energy coincides with periods of high heating needs and when the power system has excess energy. The metering system enables the Thermal storage stoves, and accounts for wind only and diesel only generation purchases separately. Thus the metering system working with control signals from the diesel plant insures that customers are not charged diesel generation, and allows the power company to offer reduced rates or substantial discounts on electricity consumed during off-peak times. It is these reduced rates that allow ETS to provide considerable savings to consumers on their energy bills as compared to alternative heating options. Renewable Energy Fund Grant Application AEA 09-004 Grant Application Page 32 of 42 9/3/2008 Metering system Wind/thermal storage requires a method of notifying the stoves of the availability of low cost wind energy, and a way to account for the difference in cost of wind versus diesel generated electricity. This is done through new meters, which will be placed on each home. The proposed metering platform creates a wireless communications link which provides fully automated, intelligent two-way communications between the powerplant and each meter. The advanced meters offer many additional features that will allow the utility to be managed more effectively, and optimize diesel station operation. The metering system will consist of 3 collector meters, one at the school, one at the washeteria/water plant, and the last at the powerhouse. Each residential customer will have a single-phase meters at their home. These meters will communicate with the data collecting 3 phase meters to create a mesh network. The meters are designed for plug and go capability, which eliminates programming and simplifies installation. This same metering system has been selected for use as it has proven to be a best practice management tool for the Alaska Village Electric Cooperative. Three of the most important features are: 1. Demand control capability that allows the utility to control thermal storage devices remotely. Thermal stoves will be enabled for green energy pricing only when a signal from the utility indicates that an excess of wind energy is available. The meter can switch devices the stoves on and off according the amount of excess wind energy available. The meters can also control other electrical devices such as water heaters and/or controlling lighting or thermostats. 2. User interface. The meters come with an in-home display device that can be used to inform the customer about their cost and energy usage. In the future they can be enabled to enter credit card information to pay bills directly. 3. Pre payment option; the proposed meters can be configured with a prepay option, which requires consumers to pay in advance of use. This feature is requested by small utilities, because it mitigates the financial risks associated with power sales and reduces embarrassing utility disconnects, billing disputes and damage to local relationships. When coupled with the associated user display in each home, the system improves financial management for both the utility and the customer. The in-home display allows utility customers to self manage energy use through real-time, informed decisions about consumption. When combined with the user interface, most customers are typically very satisfied. Through smart metering, the utility will: • Enable time of use and green energy management rate structures • Activate thermal storage devices when wind is available • Understand load profiles, and enable demand control schemes • Fairly and more accurately allocate costs of utility service according to actual consumption • Encourage conservation of electricity • Detect system problems and imbalances • Lower the cost of utility service to improve profitability • Recover related costs of utility service to improve revenues Renewable Energy Fund Grant Application AEA 09-004 Grant Application Page 33 of 42 9/3/2008 Wind Turbine brochure: 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.

Include at a minimum proposed business structure(s) and concepts that may be considered. Andrew Crow, from the University of Alaska Anchorage, is working with the Chaninik Group to develop a regional wind system business plan, based on a cooperative business model. The primary elements of this plan include utitilizing combined funding from the savings of displaced diesel fuel to pay for system maintenance, and overall administration. The greater the number of wind turbines, the more fuel displaced, the more viable the will be the financial strength of the group. One of the principles of successful operation will be to create a well paid job in each community to support the wind system operation, and to create a network of trained operators, one in each village who can support each other. A proposed source of funding would be to allocate $.05 per kilowatt hour for wind production to the operation and support. Each wind turbine will conservatively produce 150,000 kWhrs annually. This would be $7500/turbine x 5 turbine = $37500 in additional wages to utility personel. Another $.03 / kWhr would be dedicated to a replacement fund. However, a production bonus would be paid to the utility personel for any kilowatt hours produced above 200,000 kWhrs per year. This production bonus would be $.10/kWhrs. This could be as much as $4000 per turbine or $20,000. The increased cost of turbine operations would be partially paid for through the turbine bonus, increased non-fuel operating costs provided in the PCE program, and through fuel savings. The customer would still see a significant decrease in electrical rates, as the current value of kilowatt of displaced fuel is in the range of $.30/kWhr. The overall business plan would be administered by the Chaninik Group with the assistance of the automated meter reading and information technology systems. In each village the system would be administered through the use of prepaid meters. The business plan in developed will provide a detailed management and financial plan, and outline utility performance standards. 4.4.6 Analysis and Recommendations Provide information about the economic analysis and the proposed project. Discuss your recommendation for additional project development work. The renewable energy fund identified “an adequate, reliable, reasonably priced, and safe supply of energy necessary for Alaska’s basic infrastructure and economic and technological development. ” The Renewable Energy Fund is not just about the Benefit Cost Ratio. The three analytical pillars of finance and investment are; the time value of money, valuation, and risk management. The allocation decisions made by this fund must be significantly influenced by the importance of reducing the risk of the eminent collapse of rural Alaska caused by skyrocketing fuel prices. A fundamental function of this program therefore is to help communities find a way out of this crisis. The resources of the fund are too small to be scattered without a strategy for multiplying the value they create. This proposed project addresses the two central issues, reducing risk and creating value, and accomplishes these objectives in three ways: Renewable Energy Fund Grant Application AEA 09-004 Grant Application Page 38 of 42 9/3/2008 First it applies readily available innovation to provide a pathway for all Alaskans to lower costs Secondly it includes a method of developing the information needed to measure progress , and Most importantly it supports the creation of local institutional infrastructure through the strengthening of the Chaninik Wind Group which is necessary to capture and build on the value that is created by these investments This project contributes to the common good of all Alaskans in two important ways. 1. It targets the specific problem of using renewable energy to reduce fossil fuels and the cost of heat, electricity and transportation in rural Alaska. It does this through the development of a Wind Diesel Village Smart Grid, which can be used to increase efficiency of diesel only grids, and provides a method implementing widespread cost effective use of renewable energy in rural Alaska. 2. It moves all of us forward now,,,, not next year, not the year after. This project can be built this winter and be if full operation by this time next year. 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 avoided cost of ownership) • 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 Project Savings Various wind-diesel architectures, and wind systems were considered. Cost savings were estimating using the Homer Hybrid System (www.nrel.gov/homer) modeling tool and the best available information. Construction cost estimates were developed based on current construction practice, component costs and the optimal design as determined by Homer analysis. The results of this analysis are discussed below, and the low load diesel high penetration architecture using the Windmatic 17-S wind turbine system is proposed based on cost-effectiveness, simplicity and operating experience. The load growth is projected to grow at 3% as outlined in the AEA Power System Upgrade Conceptual Design Study of 2003. A step increase of 30 kW was added to the baseload in anticipation of the a new school projected to open around 2010. The HOMER modeling results were used to estimate fuel savings over the life of the project, which is 20 years. Practical experience indicates that after 15 years more efficient technology and methods will be available, at which time existing technology will likely be replaced or upgraded. Fuel Savings: Renewable Energy Fund Grant Application AEA 09-004 Grant Application Page 39 of 42 9/3/2008 HOMER results indicate near term, 2008 costs savings with five Windmatic S-17 turbines of $177,080 per year using the most recent fuel delivery price of $4.66 per gallon, and reductions in the fuel consumption at the powerplant from 85000 gallons to 47,250 gallons of fuel or approximately 40%. In addition to the fuel savings approximately 400,000 kilowatt hours available for heat. Some of this energy is anticipated to be captured by a heat recovery boiler at the school which is needed for frequency controls, to and reduce heating fuel usage from 8357 gallons to 5877 gallons. A remaining 300,000 kWhrs, or a heating fuel equivalent of 9000 gallons, would be sold into the thermal stoves into the elders residence, for half the cost of heating fuel ($6.25 / gallon, the cost BTU equivalent to $.20 per kilowatt hour, this energy would be sold as excess wind for $.10/kWhr, saving 20 homeowners, $2000 annually in their heating costs). With the current load, the five 17-S Windmatic reduces the generator fuel consumption by 47%, the school boiler fuel consumption by 35%, and the total fuel consumption by 46% over the existing system. These levels of proportional savings if achieved would represent significant decrease in the dependency on diesel fuel. In later years, as the community load grows, the proportion of displaced fuel using five turbines would drop to 38%. At which time more wind turbine capacity and thermal storage capacity can be added. The economic benefits to the community can be quantified in three ways; Annual utility fuel saving $ 160,000 Increased energy sales to utility School/Washeteria boiler (2400 gallons @ $3.00/gal) $ 7,200 Sales from thermal stoves $ 40,000 Home owner savings $ 40,000 ( community benefit) Annual financial benefit to the community $ 241,200 Table 1 – Projected Fuel Savings in Kwigillingok 2015 Power Plant Excess kWhrs # System Description Fuel Consumptio n (gal/yr) Fuel Savings (%) kWhrs for heat Fuel Savings (gal eq) 1 Existing system 124378 n/a n/a n/a 2 Add 3 17-S, retrofit 84776 31.8 72,928 2253 3 Add 4 17-S, retrofit 75673 38.9 185,584 5714 Renewable Energy Fund Grant Application AEA 09-004 Grant Application Page 40 of 42 9/3/2008 Jan Feb Mar Apr May Jun Jul Aug Sep Oct Nov Dec 0 20 40 60 80 Thermal (kW)Monthly Average Thermal Production John Deere 235 John Deere 190 John Deere 140 Boiler Excess Electricity Cost benefit Cost of improvements $ 3,200,000 Less cash match $ 1, 600,000 Total Cost of Grant Request $ 1,00,000 Present Value of cash savings, 5%, 10 years ($241,200/yr) $ 3,000,000 Benefit to cost ratio 1.8 SECTION 6 – GRANT BUDGET Tell us how much your total project costs.
