Construction and Commissioning 2.4 PROJECT DESCRIPTION Provide a brief one paragraph description of the proposed heat project. This project expands existing Kongiganak Wind Heat Smart Grid System by adding additional electric thermal storage (ETS) devices. The units themselves have been in production since the mid-1980’s as electric heat sources, but have only recently been advanced to include Grid Interactive Controls for renewable energy sources. Currently, the units and their controls are considered “off the shelf” technology and are readily available. The ETS units proposed for installation in this project are already in use in 20 homes in Kongiganak (Kong) and have realized those homes 30-50% fuel decreases (in home heating Renewable Energy Fund Round VII Grant Application - Heat Projects AEA 2014-006 Grant Application Page 4 of 28 7/2/2013 fuel) in the 10 months they have been in use. Kong has operational, utility scale, wind turbine project that produces excess wind capacity. This capacity needs to be used or the turbine production must be governed in a way that energy is wasted. Additional ETS units will provide an outlet to maximize the use of wind power to displace diesel fuel for both power generation and heating. 2.5 PROJECT BENEFIT Briefly discuss the financial and public benefits that will result from this heat project, (such as reduced fuel costs, lower energy costs, local jobs created etc.)   The project benefits are as follows: • Increased displacement of diesel fuel with wind energy • Reduced residential heating costs • Increased revenues to local utility through thermal electric sales • Reduced impact on PCE program funds • Strengthened local economy reducing export of dollars from the community to outside fuel providers. o Lower  energy  costs  within  the  community  can  attract  new  business  opportunities:  One   of  the  major  barriers  to  establishing  new  businesses  in  Alaska’s  rural  villages  is  the  high   cost  of  energy.  Lower  energy  costs  may  make  it  easier  to  start  new  businesses  in  Tunt.     o Residential  monthly  fuel  bills  will  be  lower  because  of  the  use  of  lower  cost  electricity   from  wind  for  home  heating  (for  homes  with  ETS  devices  installed)   o Revenues  to  the  local  utility  will  increase  with  additional  purchases  of  local  electricity   • Increased efficiency of existing wind system • Reduced reliance on the volatility of fuel prices • Increased education on energy use and conservation It should be noted; that prior experience has shown that with the inclusion of ETS devices has increased community awareness and support for the wind project. When residents believe the wind turbines should be working and they are not, they call the local wind technicians to find out why. This interest is driven by the direct monetary savings realized by residents who currently use an ETS unit in their home. 2.6 PROJECT BUDGET OVERVIEW Briefly discuss the amount of funds needed, the anticipated sources of funds, and the nature and source of other contributions to the project. Total Project Cost = $320,456.00 Local Cash Match (Puvurnaq Power Company) = $9,000.00 REF Funding Request = $311,456.00 2.7 COST AND BENEFIT SUMARY Include a summary of grant request and your project’s total costs and benefits below.

This project includes improvements to the power plant data collection system, which will help with project reporting and analysis of energy usage. 3.5 Project Risk Discuss potential problems and how you would address them. Project risks include the general logistical challenges of working in rural Alaska. Many times the fall barges are unable to deliver freight and fuel to Kong. If this occurs, overland winter transport will be required. As these are heavy items, shipping disruptions may affect the budget and the schedule. The technical risks are very low. This ETS infrastructure has been operating in 20 homes in Kongiganak for almost one full year. The systems are working well and there is a large demand by the community for expansion of the system. As this is a familiar project for all community and team members involved, there are no identifiable barriers or obstacles that present themselves as an impediment to completing the project as proposed. The amount of fuel capable of displacement depends on the variable nature of the wind resource, and heating requirements. While the annual amount of fuel displacement will change, the cost of wind heat will remain stable while the cost of the displace fuel rises. SECTION 4 – PROJECT DESCRIPTION AND TASKS • The level of information will vary according to phase(s) of the project you propose to undertake with grant funds. • 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. Renewable Energy Fund Round VII Grant Application - Heat Projects AEA 2014-006 Grant Application Page 9 of 28 7/2/2013 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. For pre-construction applications, describe the resource to the extent known. For design and permitting or construction projects, please provide feasibility documents, design documents, and permitting documents (if applicable) as attachments to this application. There are very limited opportunities for renewable energy in Kong; Solar and Biomass resources have virtually no opportunity in this region of Alaska. Outside of the wind, fossil fuels are the predominant source of energy for heating and electric power generation. It is anticipated that with potential improvements in conservation along with increased productivity from the wind plant, the existing Wind Heat Smart Grid Systems, is capable of displacing 35% of the community wide diesel requirement for both heat and power. Kong was selected by wind resource experts from the National Renewable Energy laboratory, as a regionally relevant monitoring location and the AEA website provides a complete wind resource assessment report. Wind resource evaluation indicates an outstanding wind resource with an average wind speed is 7.78 m/s, with the power distribution well suited for the capture of wind energy. The wind resource report includes a10 minute average of temperatures for 2004 to 2005. The 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, along with survey information to estimate the use of wind for charging of ETS units. The temperature data for the period was compared with the 20 year historical average of heating degree days. The data was used to estimate average residential heat loss and thus a fuel displacement estimate for houses equipped with ETS units. The measured period was warmer than the average year, with a total of 9607 heating degree days (11/1/04 to 10/31/05) compared with the 20 year average of 10916 heating degree days. Raw wind speed data was converted into an electrical output using the power curves for the Windmatic turbines and compared with correlations with HOMER. Fuel consumption estimates for power generation were derived from efficiency curves developed for the John Deere 6090 generator sets, and wind diesel operations were modeled assuming that the diesel generator remains on at all times, with a minimum load of 40 kW. The village load profiles are still being developed based on available data, and was consistent with “kilowatt-watt hours generated as reported PCE for 2011 and 2012. Each ETS stove has a maximum charge capacity 7.2 kW, with a heat storage capacity of 34.5 kW-hrs. A survey was conducted among the Chaninik Wind Group Villages (Tuntutuliak, Kongiganak, Kwigillingok and Kipnuk) and the average household size was determined to be 1000 square feet. Residential heat loss was based on a loss rate of 5.5 watts per square foot when outdoor ambient temperatures are 0F, which was scaled to a maximum average heat loss of 7 watts per square foot at -25F. No correlation was developed to show the affect of wind speed on heat loss, however it is assumed that there will be a strong correlation between increased heating requirements due to wind chill. However the conditions of individual houses varied quite widely across the communities. Previous interviews, surveys and data collection efforts indicated that an average Chaninik residence used 766 gallons of heating fuel annually. Modeling indicates that during the coldest Renewable Energy Fund Round VII Grant Application - Heat Projects AEA 2014-006 Grant Application Page 10 of 28 7/2/2013 days of the year hourly heat loss from the residence is equivalent to the heating capacity of the 7.2 kW ETS units. While at warmer temperatures, residential heat loss is less and energy accumulates in the stoves. The stored energy can be used to bridge lulls in the wind and extend the heating periods for some hours after the wind has stopped. 4.1.2 For Biomass Projects Only Identify any wood inventory questions, such as: • Ownership/Accessibility. Who owns the land and are their limitations and restrictions to accessing the biomass resource? • Inventory data. How much biomass is available on an annual basis and what types (species) are there, if known? Not applicable for this project. 4.2.1 Basic configuration of Existing Heating Energy System Briefly discuss the basic configuration of the existing energy system. Include information about the number, size, age, efficiency, and type of generation. The existing energy system consists of : • 2 ea John Deere 6090, 275 kW diesel electric generators • 1 each John Deere 6125 190 kW diesel electric generator • 1 each John Deere 6045 130 kW diesel electric generator • 5 each Windmatic 17s, 95 kW wind turbines, with regenerative drive control • 1 each load balancing boiler, plumbed to heat recovery loop • 20 each Steffes 2105, residential electric thermal storage units. 7.2 kW peak charge rate, 34.5 kWhrs of energy storage • Wind-diesel supervisory control system *Note: this project proposes to increase the number of Steffes ETS units from 20 to 50. This increases the capability of the power system to absorb peak wind power of 360 kW, up from 144 kW, with a commensurate increase in storage capacity up from 690 kW to 1725 kWh. * 4.2.2 Existing Heating Energy Resources Used Briefly discuss your understanding of the existing energy resources. Include a brief discussion of any impact the project may have on existing energy infrastructure and resources. 2006 2007 2008 2009 2010 2011 2012 Residential Customers 88 92 95 96 101 105 100 Population 411 427 411 436 445 465 439 kWh Generated 970,017 951,274 1,019,419 1105555 1,273,367 970,546 1,089,947 Fuel 78,096 77,820 81,658 90,100 91,833 91,647 89,811 Renewable Energy Fund Round VII Grant Application - Heat Projects AEA 2014-006 Grant Application Page 11 of 28 7/2/2013 Purchased (consumed) Cost of Fuel (total) 188,880 229,133 286,416 392,367 329,290 304,302 400,044 Cost of fuel/Gallon 2.42 2.94 3.51 4.36 3.59 3.32 4.45 Total generated non Diesel 0 0 0 0 0 0 93,337 Puvurnaq Power Company generated 1,089,900 kWhrs in 2012. The wind heat project was commissioned in October of 2012, with three wind turbines and 20 thermal storage devices. In July of 2013, the remaining two wind turbines were commissioned. Experience with the system over the winter demonstrated the ability of the system to absorb and store wind energy in complementary manner to the way it is produced. Operational experience also indicated the ability to expand the system from 20 to 50 ETS units. Currently, during a wind event, the 20 ETS units become fully charged within 5 hours and wind energy must be curtailed, because there is insufficient load. Based on modeling studies, which use 80% of the estimated annual energy production, (as per AEA economic evaluation) the wind system is expected to produce on average 1,016,000 kW-hours of electrical energy annually. With the proposed upgrade of the system from 20 ETS units to 50 ETS units. There is up to 480,000 kWhrs of the wind power available to be applied to the village electrical load displacing electrical generation at the diesel plant. Operation of a wind diesel system requires maintaining a constant balance between power generated and load. This balance is maintained through fast activation of a combination of ETS units and control of the load to an electric boiler plumbed into the heat recovery loop at the powerplant. Of the 536,000 kWh of available wind energy, in the 50 ETS scenario, 482,000 kWhrs would be sent to residential ETS units to displace home heating fuel, and the remaining 54,000 kWhrs of wind energy would be use to serve the dual purposes of heating the washeteria/powerplant heat recovery loop while buffering the power system load balance. This system configuration is intended to minimize the current need to curtail wind energy output, over the existing 20 ETS unit system, in which approximately 260,000 kWhrs of wind energy is currently curtailed. The control system for the electric thermal storage devices is able to manage the charging of ETS units in a number of ways, such as filling the emptiest ETS units first, or dividing the available surplus energy equally among the available active units. It is assumed the 536,000 wind generated kWhrs will be evenly distributed between 50 ETS over the course of the year. Using an estimate of 33 kWhrs of electrical energy as the equivalent to one gallon of heating fuel, modeling studies indicate the potential to provide each residence with 9,638 kWhrs of electricity or a displacement of 292 gallons of home heating fuel. 292 gallons is 38% of the average annual residential heating fuel usage of 760 gallons. At $ 6.93 per gallon, 292 gallons of stove oil would cost $2023. Surplus wind energy sold at $0.10 per kWhr as electric heat using the ETS devices would result in an annual household savings of $1059. This level of savings with 50 ETS units provides an annual benefit of $ 52,950 to residential customers. *Note: #2 heating fuel has a heating value of 134,000 Btu/gallon, with an 80% conversion efficiency this is equivalent to 107,200 usable Btu/gallon. This is the effective heat energy a home owner would experience. Electrical heating is nearly 100% efficient. Since Renewable Energy Fund Round VII Grant Application - Heat Projects AEA 2014-006 Grant Application Page 12 of 28 7/2/2013 efficiencies vary, an equivalent electrical energy of 33 kWhr/gal is used as the diesel fuel heating equivalent)* 4.2.3 Existing Heating Energy Market Discuss existing energy use and its market. Discuss impacts your project may have on energy customers. Fuel Cost A fuel price of $5.88/gallon ($1.55/Liter) was chosen by reference to Alaska Fuel Price Projections 2013-2035, prepared for Alaska Energy Authority by the Institute for Social and Economic Research (ISER), dated June 30, 2013 and the 2013_06_R7Prototype_final_07012013 Excel spreadsheet, developed by ISER for AEA. The $5.88/gallon price reflects the average value of all fuel prices between the 2015 (the assumed project start year) fuel price of $4.91/gallon and the 2034 (20 year project end year) fuel price of $7.04/gallon using the medium price projection analysis with an average social cost of carbon (SCC) of $0.61/gallon included. By comparison, the fuel price for Kongignanak (without social cost of carbon) reported to Regulatory Commission of Alaska for the 2012 PCE report is $4.33/gallon ($1.02/Liter), without inclusion of SCC. Assuming an SCC of $0.40/gallon (ISER Prototype spreadsheet, 2013 value), the 2012 Kongignanak fuel price was $4.73/gallon ($1.25/Liter). Heating fuel displacement by excess energy diverted to thermal loads is valued at $6.93/gallon ($1.83/Liter) as an average price for the 20 year project period. This price was determined by reference to the 2013_06_R7Prototype_final_07012013 Excel spreadsheet where heating oil is valued at the cost of diesel fuel (with SCC) plus $1.05/gallon. Fuel  cost  table  (SCC  included)   ISER  medium   cost  projection  2015  (/gal)  2034  (/gal)   Average   (/gallon)   Average   (/Liter)   Diesel  fuel  $4.91 $7.04 $5.88  $1.55   Heating  oil  $5.96 $8.09 $6.93  $1.83   Home heating – The community of Kongiganak has 100 homes. One third of these homes have been constructed within the last 10 years, the other homes were constructed at various times over the last 40 years. Surveys results indicate that residential customers are desperate for lower cost heating options, as heating fuel costs exceed $6.50/gallon currently, and prices have spiked to as high as $9.00 per gallon in 2007. Electric Thermal Storage is a method by which excess wind generated electricity can be stored as heat so that it can be used 24 hours per day. The excess wind energy will be offered to customers at $.08 to $.15/kWh, which is equivalent to heating oil equivalent of $2.60 to $5.00 per gallon. Since there is no local wood, peat or coal, wind heat in this application will be the lowest cost heating source and highly desirable. The availability of wind correlates well with heating needs. The ability to store this wind energy at night and when the loads are low, sell this wind energy for half the cost of heating fuel, and use Renewable Energy Fund Round VII Grant Application - Heat Projects AEA 2014-006 Grant Application Page 13 of 28 7/2/2013 the stored energy when needed can reduce average residential fuel use by half. This would result in an annual direct diesel fuel reduction of 11,400 gallons for these additional 30 homes. Heating fuel represents the single greatest cost of maintaining a residence. Typical costs exceed $6,000 per household. This project is expected to reduce annual household heating costs by up to $2,000 per household. Based on the energy surveys of each home in the community, the average household uses 766 gallons of heating fuel annually. Expansion of the use of number of ETS devices from 20 to 50 units will result in an average reduction of heating fuel usage of 290 gallons across 50 homes, with a resulting net individual usage of 474 gallons of home heating fuel. This represents a 38% decrease in fuel purchases. Homes with ETS units have already seen 30 to 50% decreases in fuel usage during the winter months. However, because the storage capacity of each ETS unit is 35.4 kWhrs, during wind events the 20 existing units become saturated after about 5 hours and wind turbine output must be curtailed. Curtailment requires either reducing the output of the wind turbines, or shutting them off. The addition of 30 more ETS will reduce the need to curtail wind turbine production. Additional ETS units will increase the instantaneous ability of the energy system to absorb energy from 144 kW to 360 kW, and the ability to store wind energy from 708 kWhrs, to 1770 kWhrs. This additional ability to absorb and store available wind energy, will enable more efficient use of the wind turbines and increase the overall operating hours of the diesel generators at a minimum loading. It is anticipated that the benefits of the ETS program can be improved upon, through weatherization and conservation programs, which will reduce heat loss in existing homes, enabling the further expansion of the ETS method of wind heating. Improvements in operations and maintenance, and the application of advanced airfoils are anticipated to improve the future productivity of the wind turbines. As experience with the wind systems grow, power plant operators and wind technicians are steadily improving their operating and maintenance practices. Newer airfoils, which are making their way into the marketplace, have the potential increase energy production from the existing wind plant by 15%. As experienced is gained with the system, it is anticipated that a smaller diesel generator set with lower fuel consumption may be substituted for the larger units. Most importantly, community members with ETS devices are beginning to rely on the wind heat system to lower home heating costs. This reliance has resulted in heightened awareness of and attention to the importance of reliable wind turbine operation. This interest provides additional impetus to keep the wind systems operating. Electric power generation - The operations of the Wind Heat Smart Grid Systems will benefit from additional ETS units in the communities. With more available storage capacity, the wind turbines can operate at full capacity and have dump load options for excess wind when the load is low. With more ETS units to stabilize the peaks and valleys of the wind resource, higher fuel displacement at the electric utility becomes possible and an added benefit on top of the residential fuel savings. Wind heat grids exist in three communities of Kongiganak, Tuntutuliak and Kwigillingok, (Chaninik Wind Group communities). The system in Kongiganak has been operating for 11 months. Some of the home owners with ETS units have experienced reductions in heating fuel usage of 50%. The ETS method of capturing wind energy for heat was selected because the ease of Renewable Energy Fund Round VII Grant Application - Heat Projects AEA 2014-006 Grant Application Page 14 of 28 7/2/2013 installation, proven performance and low maintenance costs. Installation requires the addition of a circuit to residential service panels and in some cases a plywood base is used to support the addition weight (650 lbs) of the unit. Local utility workers have been trained in the installation of these units and will be responsible for the majority of the installations. The supervisory control system at the power plant will be modified to expand the number of controlled units from 20 to 50. 4.3 Proposed System Include information necessary to describe the system you are intending to develop and address potential system design, land ownership, permits, energy efficiency and environmental issues. 4.3.1 System Design Provide the following information for the proposed renewable energy system: • A description of renewable energy technology specific to project location • Optimum installed capacity • Anticipated capacity factor • Anticipated annual generation • Anticipated barriers • Basic integration concept • Delivery methods • Energy efficiency measures (building envelope) Wind Electric Thermal Storage An average home in Kongiganak uses over 760 gallons of heating fuel annually. During a windy week in the winter a single home can consume an entire 55 gallon drum of heating fuel. This project expands the capture the wind produced energy and uses it to displace home heating fuel, using Electric Thermal Storage (ETS). ETS is the method of capturing excess wind generated electricity as heat and storing it for use at a later time. An ETS unit is an insulated metal box, about the same size as a Toyo Stove, which contains electric heating elements embedded within special, high-density ceramic bricks. These bricks are capable of storing vast amounts of heat for extended periods of time. The current wind system consists of 5 each, Windmatic 17S 95 kW wind turbines, with a total installed capacity of 475 kW. The average load in the community is around 175 kW. During wind events the load on the diesel generators at the power plant is reduced to 40 kW, and with the exception of 20 kW diverted to the heat recovery load balancing system, wind energy is used to meet the community electrical load. During most wind periods, surplus wind is produced. This surplus is diverted to residential ETS units where it is either used immediately or stored to displace home heating fuel. ETS units are activated through a signal from the power plant supervisory controller. Each ETS unit is sub metered to keep track of surplus wind energy consumption. A thermostat regulates the delivery of the heat to the residence. The excess wind energy is sold for $.10 per kilowatt-hour. This wind heat system provides a low cost, low maintenance method of home heating, which reduces the homeowners’ heating bill and increases revenues to the local utility Renewable Energy Fund Round VII Grant Application - Heat Projects AEA 2014-006 Grant Application Page 15 of 28 7/2/2013 that provides local jobs. A model was developed to correlate charging of ETS units with available wind energy. Heating surveys indicate that average hourly living room heat for a residence in Kongiganak is 14,000 Btu/hr. Each ETS unit can both produce and store up enough energy depending on the charge schedule to output 20,000 Btu/ per hour per unit, 24 hours a day. This is similar in size and energy output to a Toyo Stove. The pictures below present an exterior and interior view of a room unit. The dimensions are 58 inches in length, 24.5 inches in height, and 10.5 inches in depth, and when filled with heat charge bricks each unit weighs 690 lbs. The room units (shown above) are non-ducted and are designed to heat the room or area where they are placed. These heaters can be used in new construction applications or as a retrofit or supplement to an existing heating system, and only require an electrical connection to operate. A fan inside the unit circulates stored heat evenly and quietly as the room thermostat calls for heat. Individual units are easy to operate and require very little maintenance. The amount of heat stored in the brick core of the heater is regulated (either manually or automatically) according to seasonal weather conditions using either the onboard microprocessor, or manual override by the homeowner. This project expands the use of residential ETS in the Kongiganak Wind Heat Smart Grid Systems from 20 to 50 homes. Funding is being requested to install 30 new ETS electric devices and commission the supervisory control system to include the control and reporting of the additional units. ETS devices are manufactured in Dickinson, North Dakota by Steffes Corporation. The multiple unit control technology that was jointly developed by Steffes and IES. Steffes has been manufacturing ETS units since the mid-1980’s and over the last 2 years have adapted these units for advanced wind diesel micro grid integration. This “off the shelf” technology is currently in use in Kongiganak. There is widespread support for the expansion of this project in Kong. The useful-life of the ETS system is twenty years. ETS units are simple, require very little maintenance cost to maintain and are simple to repair. The 20 homes in Kongiganak with ETS units have experienced 30-50% reductions in heating Renewable Energy Fund Round VII Grant Application - Heat Projects AEA 2014-006 Grant Application Page 16 of 28 7/2/2013 fuel usage over the last 10 months. Additional ETS storage capacity is needed in Kong in order to prevent the curtailment of wind production, and make use of the available wind energy. This project involves the installation of 30 Electric Thermal Storage units, each rated at 36 kWhrs of storage and a peak power of 7.2 kW each. It is estimated that these units will be used 10 to 11 months per year. The total amount of heat available to be absorbed by the residential stoves was derived using available data and HOMER production modeling that incorporates available windpower. Additional modeling was done to estimate the effects of varying outdoor temperature with village electrical and residential heating loads. This model was used to provide an estimate heat required for and energy available to electric thermal storage devices. Village surveys indicate the average village household is 1000 sq ft, and average heating fuel usage of 766 gallons annual. An average heat loss of 6.5 W/sq.ft. was used to estimate heat loss from each building. Designers of electric heating system use a range of 5 W/sq. ft. for well insulated homes in moderate climates, and 10.5 W/sq. ft. for sizing residential electric heating systems, and serves as a conservative estimate of heat energy usage. Existing data was used to compare heat loss and wind production using ten year averages of “degree day” estimates for the community of Konginganak developed from historical weather data. As the ETS units are a subordinate power use to the community electrical load and are only charged using surplus wind, a model was developed to compare wind power production with community heat and power needs to estimate ETS usage. Assumptions for the model: an average heat loss of 7.5 watts per square foot which is based on a temperate zone - where the minimum temperature is around 0 F. Estimated ETS use factor assumed a maximum output at 0F and at its minimum output 60 F, which is equivalent to 60 degree days. The average number of heating degree days was used to describe the duty cycle of the ETS unit between heating and energy storage. The table below provides an indication of kW-hrs of heat use per day per household by month. When extended to the total number of households in the community, it is estimated that sufficient surplus wind power is currently available to meet a residential heat load equivalent for 50 homes. The total of 600,000 kW-hrs that could be sold for residential heat - at 10 cents is $60,000 per year. As the community’s experience with wind heat increases, the interest in and demand for ETS units has grown. Kongiganak has 100 residences. Almost every home owner has requested the installation of an ETS unit. It is anticipated the efficiency of the ETS and the available wind energy can be maximized through increased insulation and weatherization of homes. Even though there winds are strong in December and January and the wind heat will need to be supplemented with existing heating systems such as boilers or wood heat, as it would require 10 turbines to keep up with the residential heating loads. During the months of July and August, about 20,000 kWhrs of surplus wind may not be needed. However, current estimates indicate that with 50 ETS devices in the existing system, each household on average will save 285 gallons of fuel annually. The cost savings to the home owners at $.10 per kilowatt ($2.90 heating fuel = (285 x ($ 6.93 - $2.90) = $1148/household. 50 households = $57,427 is the full community benefit to the residential customer annually. For the 30 new stoves to be installed, it equates to $688,800.00 for the life of the project. The benefits to the utility include: Additional energy sales (413,250 kWhrs @ $.10 = $41,325) The cost of installation for 30 additional ETS units is: $320,456.00 Renewable Energy Fund Round VII Grant Application - Heat Projects AEA 2014-006 Grant Application Page 17 of 28 7/2/2013 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 obtain harvest contracts and access issues.

Installation of project materials will occur at the Puvurnaq Power Company power plant and in individual homes and buildings on an opt-in basis with full participation from the building and homeowners. 4.3.3 Permits Provide the following information as it may relate to permitting and how you intend to address outstanding permit issues. • List of applicable permits • Anticipated permitting timeline • Identify and discussion of potential barriers There are no permitting requirements for this project. Community members will participate based on an opt-in process with final selection occurring based on determination by the Puvurnaq Power Company, Kongiganak Traditional Council and in accordance with limitations due to the existing distribution system. 4.3.4 Environmental Address whether the following environmental and land use issues apply, and if so how they will be addressed: • Threatened or endangered species • Habitat issues • Wetlands and other protected areas • Archaeological and historical resources • Land development constraints • Telecommunications interference • Aviation considerations • Visual, aesthetics impacts • Identify and discuss other potential barriers There are no environmental or land use issues, no SHPO clearances, no development constraints, no telecommunications interference, and no aviation considerations. There are no visual or aesthetic impacts and no other potential barriers to project completion. 4.4 Proposed New System Costs and Projected Revenues (Total Estimated Costs and Projected Revenues) The level of cost information provided will vary according to the phase of funding requested and any previous work the applicant may have done on the project. Applicants must reference the source of their cost data. For example: Applicants records or analysis, industry standards, consultant or manufacturer’s estimates. 4.4.1 Project Development Cost Provide detailed project cost information based on your current knowledge and understanding of the project. Cost information should include the following: Renewable Energy Fund Round VII Grant Application - Heat Projects AEA 2014-006 Grant Application Page 18 of 28 7/2/2013 • Total anticipated project cost, and cost for this phase • Requested grant funding • Applicant matching funds – loans, capital contributions, in-kind • Identification of other funding sources • Projected capital cost of proposed renewable energy system • Projected development cost of proposed renewable energy system Total anticipated project cost and cost for this phase is $320,456.00 Requested grant funding is $311,456.00 Applicant matching funds are $9,000.00 in cash The cost estimates for the project are based on varying sources of current quotes, estimated materials and labor projections, and previous invoices on installation of ETS devices in Kong. All grant funds will be expended on costs directly related to the performance of the scope of work and administration and reporting of grant activities. The match funds contribution for the project come from the Puvurnaq Power Company as a cash match towards payroll for local technicians to perform the ETS installation. This provides a total of $9,000.00 to the project in labor payroll and decreases the AEA REF fund request to $311,456.00. The summary cost items below include freight, all materials for commissioning, and contingency costs. 1 Final determination and survey of homes for install (community designation) $ 18,250 2 Purchase ETS units, hardware and controls for install $ 151,922 3 Freight all items to site $ 47,775 4 Install hardware and ETS units $ 48,759 5 Commission additional controls unit $ 43,300 6 Monitor and Reporting $ 10,450 Total Project Cost $ 320,456 Match Funds From Puvurnaq Power Company (payroll) $ 9,000 REF Grant Funds Requested $ 311,456 4.4.2 Project Operating and Maintenance Costs Include anticipated O&M costs for new facilities constructed and how these would be funded by the applicant. (Note: Operational costs are not eligible for grant funds however grantees are required to meet ongoing reporting requirements for the purpose of reporting impacts of projects on the communities they serve.) Local utility operators and installation technicians will incorporate the additional units’ O and M needs into their existing operations plan. System SCADA outputs are analyzed on a daily basis to ensure functionality of existing wind system components and ETS units. Remote access through broadband connection allows engineers and technicians from all over the country to Renewable Energy Fund Round VII Grant Application - Heat Projects AEA 2014-006 Grant Application Page 19 of 28 7/2/2013 access components for assisted troubleshooting and repair. The increased revenue brought to the local utilities from sales of excess wind capacity allows them to set budgets for maintenance and additional equipment costs due to the installation of new components and additional ETS devices. The ETS units require little to no maintenance and have components that are easily replaceable and very cost effective, if they should fail. Initial spare parts kits are included in the total project cost. 4.4.3 Heat Purchase/Sale The heat purchase/sale information should include the following: • Identification of potential energy buyer(s)/customer(s) • Potential heat purchase/sales price - at a minimum indicate a price range • Proposed rate of return from grant-funded project • Utility savings for displaced diesel generation – the proposed system would displace approximately 71,338 gallons of diesel at the utility. At a current bulk fuel purchase price of $3.95 a gallon1, annual saving of $281,785 are expected. For an expected project life of 20 years, that totals $5,635,702.00 in benefits. However, $3.95 is the lowest wholesale price in the last 6 years. Experience indicates that the wholesale cost of diesel fuel is unstable, and is unlikely to trend down over the long term. The Institute for Social and Economic Research for the State of Alaska uses a long term average fuel cost in the $5.00 per gallon range with annual escalation of 2% per year for estimating future investments. Should these prices materialize, the benefits of the investments would be closer to $8,000,000. • Lower heating costs - homeowners who have the ETS devices can expect to have savings of 220 gallons of diesel fuel per year displaced with excess wind energy. Excess wind energy is sold into ETS devices at around $.10 per kilowatt hour, equivalent to approximately $2.90/gallon heating fuel. Residential customers are currently purchasing in excess of 770 gallons of fuel for nearly $7.33 per gallon. (7.33-2.90) x 220 = $975 annual savings. 40 residential units x $975 = $39,000.00 savings annually, with expected project benefit of over $780,000 over the 20 year life of the project. • Increased revenues to the utility - result from heat sales of more than 250,000 kWhrs of wind heat electricity as heat for $25,000.00. • A business plan for the Wind Heat project was developed. Under this plan, residential customers exceeding the 500 kWhrs per month of Power Cost Equalization (PCE) subsidized electricity would see a reduction in their effective residential rate of $.05 per kilowatt/hour or more, depending on the additional rate requirements of the utility. For about 1/3 of residential customers, this would represent a savings of $5.00 to $25.00 per month, or $60 to $300 annually. 4.4.4 Project Cost Worksheet Complete the cost worksheet form which provides summary information that will be considered 1 Source: State of Alaska, Alaska Energy Authority Power Cost Equalization 2012 Annual Report Renewable Energy Fund Round VII Grant Application - Heat Projects AEA 2014-006 Grant Application Page 20 of 28 7/2/2013 in evaluating the project.

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 (gallons and dollars) over the lifetime of the evaluated renewable energy project. In order for the applicant to receive credit for ting fuel displaced the applicant must provide the most recent invoice for heating fuel purchased. • Anticipated annual revenue (based on i.e. a Proposed Heat Purchase Agreement price, RCA tariff, or cost based rate) • Potential additional annual incentives (i.e. tax credits) • Potential additional annual revenue streams (i.e. green tag sales or other renewable energy subsidies or programs that might be available) • Discuss the non-economic public benefits to Alaskans over the lifetime of the project Renewable Energy Fund Round VII Grant Application - Heat Projects AEA 2014-006 Grant Application Page 23 of 28 7/2/2013 The Yup’ik village of Kongiganak is located on the west shore of Kuskokwim Bay, west of the mouth of the Kuskokwim River. It lies 70 miles southwest of Bethel and 451 miles west of Anchorage at 59.88000N and -163.0540W. Kong is a Census Designated Place in the Bethel Region. Kongiganak is located in a marine climate. Annual precipitation averages 22 inches, with 43 inches of snowfall annually. Summer temperatures range from 41 to 57 °F, and winter temperatures average 6 to 24 °F. There are, currently, almost 500 individuals living in Kongiganak. There has been slow but consistent growth over the past decade. There are 102 housing units although eight of these are vacant. The median family income in Kong is approximately 35,536, however 24.35% of the population lives at or below the poverty line, and 46% make $5,000 or less every year compared to 20% statewide who make $5,000 or less annually. The unemployment rate is around 23%. As is the case in other Alaskan villages, the residents of Kong still rely on subsistence hunting, fishing and gathering as a lifestyle. Kongiginak produces power at the Puvurnaq Power Company power plant using diesel fuel. They also utilize five Windmatic 17s wind turbines. The base rate for electricity is $.65 kWh. Residents heat their homes using heating fuel #1. This fuel, like diesel and gasoline is barged into the community between spring thaw and winter freeze. The residential rate for heating fuel varies and is currently $6.21 gallon. Economic and Environmental Benefits to the Tribal Communities Alaskan villages are being impacted by global warming, resulting in profound impacts on subsistence and cultural activities, erosion, land use, and endangered species. Any reduction of fossil fuel use has a positive impact on quality of life in rural Alaska. This project further benefits the communities through: 1) Supporting the long term energy sufficiency goals of community of Kongiganak by: • Reducing heating costs to 30 additional homes • Increasing revenues to the local utility for thermal electric sales for residential heat • Making benefits of wind and other potential renewables available to residential home owner • Increasing the ability to store wind energy as heat for later use • Retaining more money within the community instead of exporting to outside fuel providers 2) Social and Cultural Benefits: This project will create social and cultural value to the communities above and beyond the direct benefits to tribal members in the villages: • Increased local employment • Education on energy use and conservation • Prior to installation of renewable energy systems, a large percentage of individual tribal member income was spent to purchase diesel fuel. In the future, more funds will stay in the community for two reasons: + Residential monthly fuel bills will be lower because of the use of lower cost electricity from wind for home heating (for homes with ETS devices installed) Renewable Energy Fund Round VII Grant Application - Heat Projects AEA 2014-006 Grant Application Page 24 of 28 7/2/2013 + Revenues to the local utility will increase with additional purchases of local electricity • Lower energy costs within the community can attract new business opportunities + One of the major barriers to establishing new businesses in Alaska’s rural villages is the high cost of energy. Lower energy costs may make it easier for tribal members to start new businesses in their communities. SECTION 6– SUSTAINABILITY Discuss your plan for operating the completed project so that it will be sustainable. Include at a minimum: • Proposed business structure(s) and concepts that may be considered. • How you propose to finance the maintenance and operations for the life of the project • Identification of operational issues that could arise. • A description of operational costs including on-going support for any back-up or existing systems that may be require to continue operation • Commitment to reporting the savings and benefits The continued O&M for ETS units will be supported by the additional revenue that they generate for the PPC utility totaling well beyond the O&M requirement for the ETS units. Potential operational issues would include the need for replacing control units and/or ETS units, which would be provided for under warranty, Other operational costs outside of the warranty can be covered by the increased utility revenues. In conjunction with previously gathered baseline data, additional up-to-date baseline data will be gathered from each participating ETS unit home as to their current “pre ETS” household fuel consumption and this information will be entered into a database. Existing Wind Heat Smart Grid system SCADA collects ETS unit energy consumption on a sub second basis and produces daily, weekly and monthly reports. This information will be analyzed, aggregated and averaged for total project data with outliers for high and low production also being made available. Any anomalies found during the required year of verification will also be determined and outlined. Fossil fuel reduction will be available on a monthly, quarterly and annual basis for all ETS units installed on the Wind Heat Smart Grid. SECTION 7 – READINESS & COMPLIANCE WITH OTHER GRANTS Discuss what you have done to prepare for this award and how quickly you intend to proceed with work once your grant is approved. Tell us what you may have already accomplished on the project to date and identify other grants that may have been previously awarded for this project and the degree you have been able to meet the requirements of previous grants. The proposed work on this project would begin immediately upon execution of a grant agreement. Community buildings and homes would be designated for installation and project materials would be procured to be available in time for the last barge of the 2014 season. Installation and commissioning of ETS units would be completed before the end of 2014 with monitoring and data collection occurring into 2015. Renewable Energy Fund Round VII Grant Application - Heat Projects AEA 2014-006 Grant Application Page 25 of 28 7/2/2013 Kongiganak has worked through numerous grant opportunities, including DCCED, AEA REF, EECGB and others. All grants are executed in compliance and projects have been completed to proposed scope. SECTION 8 – LOCAL SUPPORT AND OPPOSITION Discuss local support and opposition, known or anticipated, for the project. Include letters of support or other documentation of local support from the community that would benefit from this project. The Documentation of support must be dated within one year of the RFA date of July 2, 2013. The community of Kongiganak is supportive of this project and the installation of additional ETS units. During strategic energy planning meetings, the community identified installation of ETS units as one of their top energy priorities for the community. Since the commissioning of the existing ETS units, additional residents have been appealing to the Tribal Council and PPC utility for additional units. See attached Council Resolution. There is no known or anticipated opposition to the project. SECTION 9 – GRANT BUDGET Tell us how much you are seeking in grant funds. Include any investments to date and funding sources, how much is being requested in grant funds, and additional investments you will make as an applicant. The budget for this project will come from REF funding and a local match from PPC for laborer and technician payroll during the install of the ETS units. PPC is committed to providing the match for this project, as funding will create additional employment opportunity in our community and great savings to our residents. The metering and monitoring equipment necessary for operations reporting is already installed in the PPC power plant with the existing ETS units. Total anticipated project cost and cost for this phase is $320,456.00 Requested grant funding is $311,456.00 Applicant matching funds are $9,000.00 in cash The cost estimates for the project are based on varying sources of current quotes, estimated materials and labor projections, and previous invoices on installation of ETS devices in Kong. All grant funds will be expended on costs directly related to the performance of the scope of work and administration and reporting of grant activities. The match funds contribution for the project come from the Puvurnaq Power Company as a cash match towards payroll for local technicians to perform the ETS installation.
