Installing the necessary heat exchangers, piping, pumps, and controls necessary for implementation has been done in several communities before and proven effective for many years. 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. 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. The energy resource available is the heat from the water jackets on the power plant engines. The heat available from the power plant significantly exceeds that required by the new and existing WTPs, washeteria, clinic, Head Start Building, and school most of the year, as indicated by the attached 2012 Heat Recovery Feasibility Study.

Include information about A heat recovery utilization spreadsheet has been developed to estimate the recoverable heat based on monthly total electric power production, engine heat rates, building heating demand, washeteria loads, heating degree days, passive losses for power plant heat and piping, and arctic piping losses. The spreadsheet utilizes assumed time -of -day variations for electric power production and heat demand. Power generation data from AVEC for fiscal year 2011 is used in the spreadsheet. The estimated heat rejection rate for the power plant gensets, Caterpillar 3456 series with marine jackets, was used to estimate available recovered heat. Heating degree-days for Stebbins were utilized for this site. All arctic piping is assumed to be routed below grade. All power plant hydronic piping is assumed to be insulated with 2 inches of insulation. The proposed conceptual generator plant design was used to estimate the heating load for the power plant, which includes the power house, an insulated storage module, and one living quarters module. Following is a summary of annual fuel use and estimated heat utilization in equivalent gallons of fuel for each building: Facility Estimated Estimated Heat Annual Fuel Delivered W/ Intertie Use (Gallons) (Gallons) Old Water Treatment Plant 4,815 4,815 New Water Treatment Plant 5,318 5,318 Washeteria 7,452 2,653 Stebbins School 46,474 39,437 Clinic 2,353 2,353 Head Start Building 2,353 2,353 Total 68,765 56,929 4.2.2 Existing 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. The existing WTP/washeteria, newly planned WTP, clinic, Head Start Building, and school are hydronically heated. The AVEC power plant is currently in design with site work already started. It is expected to provide most of the recovered heat necessary to serve the nearby public buildings. An expected AEA13-006 Grant Application Page 8 of 21 7/3//2012 Renewable Energy Fund Round 6 Grant Application i � ENERGY AUTHORFTY intertie to St. Michael is currently in planning. AVEC is considering integration of wind power generation into its new power plant at some point in the future. 4.2.3 Existing Energy Market Discuss existing energy use and its market. Discuss impacts your project may have on energy customers. Heating oil must be barged in during the summer months. The impact of this project will be to ultimately reduce the overall use of oil by approximately 57,000 gallons per year. While this reduction will not change the price of oil in Stebbins, it will significantly reduce the community's consumption of oil, replacing that consumption with recovered heat from the diesel engines and, potentially, excess wind energy in the future. 4.3 Proposed System Include information necessary to describe the system you are intending to develop and address potential system design, land ownership, permits, and environmental issues. 4.3.1 System Design Provide the following information for the proposed renewable energy system: • A description of renewable energy technology specific to project location • Optimum installed capacity • Anticipated capacity factor • Anticipated annual generation Anticipated barriers • Basic integration concept ■ Delivery methods The heat recovery system captures water jacket heat generated by the AVEC power plant that is typically rejected to the atmosphere by the radiators. The recovered heat is transferred via below -grade arctic piping to the end users. The objective is to reduce the consumption of expensive heating fuel by utilizing available recovered heat. Although heat recovery is an excellent method of reducing heating fuel costs, recovered heat is a supplementary heat source and it is imperative that the end -user facility heating systems are operational at all times. Hot engine coolant is piped through a plate heat exchanger located at the power plant. Heat is transferred from the engine coolant to the recovered heat loop without mixing the fluids. Controls at the power plant are used to prevent subcooling of the generator engines and associated reduction in electric power production efficiency. The recovered heat fluid is pumped through buried insulated pipe to the end -user facilities, and is typically tied into the end -user heating system using a plate heat exchanger. AVEC PLANT TIE-IN Because the AVEC plant is being designed for recovered heat, no modifications to the AVEC power plant cooling system are included or anticipated, except those required to connect the arctic piping to the power plant heat exchangers. AEA13-006 Grant Application Page 9 of 21 7/3//2012 Renewable Energy Fund Round 6 Grant Application L -� ENERGY AUTHORITY All heat recovery piping will be insulated with a minimum of 2-in. insulation and have an aluminum jacket where exposed to the weather. All valves will be either bronze ball valves or lug style butterfly valves with seals compatible with 50/50 glycol/water mixtures at 200F. Air vents, thermometers, pressure gauges, drain valves, and pressure relief valves will also be provided. ARCTIC PIPING (Recovered Heat Loop) The proposed arctic piping is based on Rovanco's Rhinoflex preinsulated pipe design with a 4-in. PEX-A carrier pipe, 1-in. polyurethane foam insulation, and HDPE outer jacket. The piping will be buried approximately 2 ft deep and run from the AVEC plant within existing rights -of -way to the end -user buildings. Because multiple users are connected to the system, a variable speed pump located at the new power plant will circulate heating fluid to each user from the AVEC facility. When users are not actively consuming recovered heat, their systems will throttle down heating fluid flow to minimize power consumption. Electric charges for the circulation pump will be shared based on use of recovered heat. The recovered heat fluid will be a 50/50 Propylene Glycol/Water solution to provide freeze protection to the piping. END -USER BUILDING TIE-INS End -user building tie-ins typically consist of brazed plate heat exchangers with motorized bypass valves to prevent back feeding heat to AVEC or other users. Plate heat exchangers located in the end -user mechanical rooms will be tied into the boiler return piping to preheat the boiler water prior to entering the boiler. Where required, a heat injection pump will be used to avoid introducing excessive pressure drop in the building heating system. The maximum anticipated delivered recovered heat supply temperature is about 190F. When there is insufficient recovered heat to meet the building heating load, the building heating system (a boiler or heater) will fire and add heat. Off the shelf controls will lock out the recovered heat system when there is insufficient recovered heat available. Typical indoor piping will be type-L copper tube with solder joints. Isolation valves will be solder end bronze ball valves or flanged butterfly valves. All piping will be insulated with a minimum of 1-in. insulation with an all -service jacket. Flexibility will be provided where required for thermal expansion and differential movement. Air vents, thermometers, pressure gauges, drain valves, and pressure relief valves will also be provided. Each facility will also receive a BTU meter to provide recovered heat use totalization and instantaneous use. PRIORITIZATION OF RECOVERED HEAT Recovered heat prioritization is accomplished by setting the minimum recovered heat temperature for each user, with successive load shedding as the recovered heat loop AEA13-006 Grant Application Page 10 of 21 7/3//2012 Renewable Energy Fund Round 6 Grant Application ■ �. ENERGY AUTHORMY temperature falls. The user with the highest allowable recovered heat temperature will be removed from the system first. The user with the lowest allowable recovered heat temperature will be removed from the system last. The system will also provide freeze protection in the event a user's boiler system temperature falls below a minimum temperature, typically 50-100F. 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. There are no apparent conflicts with rights -of -way for the arctic piping between the power plant and the end -user buildings, as the route is entirely within existing road rights -of -way and on city and AVEC property. A Heat Sales/Right-of-Entry Agreement will be required between AVEC and the end users to define the parties' responsibilities, detail the cost of recovered heat, and authorize the connection to the power plant heat recovery equipment. 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 No permits are anticipated for this heat recovery project. 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 ANTHC will consider all potential environmental concerns associated with this project. ANTHC has extensive experience using the comprehensive Indian Health Service (IHS) environmental review procedures for conducting environmental analysis of all health and sanitation facilities projects in all stages of development, as outlined in the IHS Environmental Review Manual issued in January 2007.

The remaining $21,975 is being donated by ANTHC in the form of project and program management services. 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.) As with all heat recovery systems, the operating cost will be minimal. The controls are automated both at the power plant and at facilities served. The most expensive components in the heat recovery system are the heat exchangers, and they normally have a minimum of a 30- year life. Minor maintenance costs will occur periodically, but they will be limited to valves, pumps, and possibly some replacement glycol. Approximately $500 per year should be budgeted for maintenance. 4.4.3 Power Purchase/Sale The power purchase/sale information should include the following: Identification of potential power buyer(s)/customer(s) Potential power purchase/sales price - at a minimum indicate a price range Proposed rate of return from grant -funded project A standard Heat Sales Agreement specifying a heat sales rate of 30% of displaced oil for PCE recipients and 50% for non-PCE recipients will be executed with AVEC, the supplier of the recovered heat. This amount will be based on AVEC's cost for fuel which is much lower than the retail price of fuel in the village. A standard BTU meter will be used to measure the amount of recovered heat used at each facility. AVEC will apply revenue from heat sales to system O&M AEA13-006 Grant Application Page 12 of 21 713H2012 Renewable Energy Fund Round 6 ; Grant Application ENERGYAUTHORfTY and matching funds recovery, and then to offset power generation fuel costs for the Stebbins -St. Michael service area 4.4.4 Project Cost Worksheet Complete the cost worksheet form which provides summary information that will be considered in evaluating 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 • Anticipated annual revenue (based on i.e. a Proposed Power Purchase Agreement price, RCA tariff, or cost based rate) • Potential additional annual incentives (i.e. tax credits) • Potential additional annual revenue streams (i.e. green tag sales or other renewable energy subsidies or programs that might be available) • Discuss the non -economic public benefits to Alaskans over the lifetime of the project The potential fuel displacement is 57,000 gallons of the #1 heating fuel oil used at the existing water treatment plant/washeteria, new water treatment plant, Head Start Building, clinic and school. The cost of the fuel is $4.21 per gallon (summer 2012). The annual cost of fuel displaced therefore equals $240,000. Over the 30-year life of the heat recovery system, the savings will be $7,200,000 in today's dollars. A heat sales agreement specifying a heat sales rate of 30% of displaced oil for PCE recipients and 50% for non-PCE recipients will be executed. AVEC will apply revenue from heat sales to system O&M and matching funds recovery, and then to offset power generation fuel costs for the Stebbins -St. Michael service area. (AVEC's Recovered Heat Utilization Policy is attached. There are no other known incentives or revenue streams that will result from this project. The benefits to the community of this project include a reduction in the amount of fuel required by the community, much more efficient use of the recovered engine heat, and a direct benefit to each community member. SECTION fr 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. AEA13-006 Grant Application Page 15 of 21 7/3//2012 Renewable Energy Fund Round 6 ion:,, Grant Application M111111111ED ENERGY AUTHORrrY • 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 This project increases the sustainability of the community facilities by reducing fuel consumption by $7,200,000 (in today's dollars) over the 30-year life of the project. The minimal maintenance and operating cost can be funded out of its own revenue stream and out of its savings over the 30-year life of the project. The existing boilers will be maintained in the six facilities as primary heat, although they are not expected to be needed when recovered heat is available.

RECOVERED HEAT UTILIZATION POLICY I. OBJECTIVE To state policy guidelines for the installation and operation of heat recovery and utilization systems on AVEC diesel power plants and to state policy guidelines for use of revenues from such systems. II. POLICY I. Where available, and not incompatible with electric power generation operations, AVEC will make excess recovered heat available for sale and purchase to qualified users on an interruptible basis. 2. AVEC will carefully evaluate making engine exhaust heat available through stack recovery systems due to their maintenance and cleaning requirements. 3. To qualify, the user must enter into a contract with AVEC for an approved diesel jacket water recovery system. The contract may specify terms, conditions and standards which may include but not necessarily be limited to: minimum return temperature, BTU meter locations, pump locations, heat exchanger flow rates, payment terms, rights of access to common facilities, rights of way for heat distribution lines, and responsibility for construction and maintenance. 4. For recovered heat delivered to the customer's heat exchanger at the AVEC power plant, the fee will be not less than: 30% of the avoided fuel cost for a community facility that is eligible for PCE , or 50% of the avoided fuel cost for any other facility. The avoided fuel cost is determined by AVEC's delivered fuel cost in the prior calendar year for the site. 5. If AVEC is required to assume ownership or maintenance responsibility for heat distribution systems beyond the connection to the end user's heat exchanger at the power plant, then AVEC may charge for the heat up to the full fuel value and additional capital or maintenance costs that may be necessary to deliver the heat. 6. AVEC recognizes that users may wish to make a contribution -in -aid of construction or offer investments for offsetting credit for recovered heat L purchases. In such cases then the minimum value for the recovered heat 3012.1 shall be as determined in Item 4 above and shall consider the economic life of the asset that may be offered. 7. If installation of a BTU meter is not economical, or if AVEC and the user mutually agree, then the revenue amounts to be determined in Items 4, 5 and 6 may be determined by mutual agreement and equal payments may be made on monthly, quarterly, or other periodic basis. 8. AVEC will apply revenues from recovered heat systems as follows: a) to fund a reserve for periodic maintenance and renewal of that portion of a system under AVEC's responsibility; b) to refund any matching funds or contributions advanced from AVEC's general fund for system construction; and c) to refund power plant upgrades to improve the availability of recovered heat to end -users, this would include insulating of buildings and equipment, marine jacket installation on diesel engines, metering and monitoring systems and other beneficial upgrades. d) to offset fuel costs for the service area served by the local AVEC generation plant, thereby reducing the fuel cost charge per kWh for all electricity supplied in that service area. RESPONSIBILITY 1. The President and CEO is responsible for implementation of this policy and may further delegate selected responsibilities to subordinates to carry out this policy.

The total estimated annual heating fuel used by all six buildings is approximately 57,000 gallons. The expected annual savings is $240,000 in fuel costs. The payback is based on a 2011 fuel price of $4.21/gallon and an estimated 2011 project cost of $1,243,000. Assuming construction in 2014, the design and construction cost with 2 years of 3% escalation is $1,319,000. The AVEC power plant is currently in design with site work already started. It is expected to provide most of the recovered heat necessary to serve the nearby public buildings. An expected intertie to St. Michael is currently in planning. AVEC is considering integration of wind power generation into its new power plant at some point in the future. The impact of the wind power is unknown at this point, but with an intertie to St. Michael (necessary for wind power), it is expected that there will still be substantial recoverable heat available. 1.0 INTRODUCTION The Alaska Native Tribal Health Consortium (ANTHC) reviewed the feasibility of providing recovered heat from the future AVEC power plant (construction beginning in 2012) to the new WTP (construction beginning in 2013), existing WTP, community school, and adjacent community buildings in Stebbins. ANTHC also developed a budgetary project cost estimate based on Force Account Construction, including Engineering and Construction Administration. The new WTP is designed to integrate recovered heat to heat the building, preheat the incoming raw water, and heat two water storage tanks (WSTs). Space has been allocated for a heat recovery heat exchanger and pumps, piping connections have been provided, and the control system is designed for easy integration. The existing WTP provides heat to the circulating water lines and heat to one of the WSTs. The system was not designed for waste heat and will require controls and installation of new heat transfer equipment, including a new heat exchanger and new circulating pumps. Once the water treatment functions have been moved to the new WTP, space will be available for new equipment to be added. The existing washeteria building is hydronically heated. The city reports fuel consumption of 7,400 gallons/year and importantly, much of this load is present in the summer as well as winter. New equipment will include a large brazed plate heat exchanger, a new circulator pump, and controls to prevent back feeding of heat to the generator facility. The existing head start building and community clinic also are hydronically heated. It is anticipated that recovered heat could also be used in these buildings as well. The existing school has a reported fuel consumption of approximately 46,500 gal / year and is hydronically heated with oil fired boilers. A site investigation of the facility has not been done at this time, but it is anticipated that space can be found for a heat recovery heat exchanger, associated pumps and controls. This report assumes that space for heat recovery equipment at the power plant will be included in the construction of the power plant, with necessary controls and heat exchangers in place. Additional assumptions have been made in the development of this report, including, but not limited to, the proposed arctic piping route, building heating loads, and flow rates and pressure drops of the power plant heat recovery system. It is anticipated that refinements in arctic pipe size and routing, pump and heat exchanger sizing, and other design elements will be required as the project progresses to final design. Available as -built information was obtained from AVEC regarding the 2011 power plant electrical loads. End -user annual fuel use was obtained from a variety of sources, including the City, Alaska Rural Utility Cooperative (ARUC), and engineering estimates. Where possible, reported fuel consumption was used to validate engineering estimates. Site visits were made to the existing WTP and washeteria to confirm accuracy of information obtained. 2.0 OVERVIEW The purpose of this study is to provide an estimate of the heat that can be recovered from the AVEC power plant diesel engines and used to offset heating oil consumption at the nearby public buildings. Useable recovered heat is quantified in gallons of heating fuel saved using a gross heating value of 134,000 BTU per gallon of #1 arctic diesel fuel and an overall boiler efficiency of 75% for a net heating value of 100,000 BTU per gallon. The public buildings eligible for heat recovery are located within 600-foot radius of the AVEC power plant. This analysis evaluates the potential to provide recovered heat to the nearby public buildings. The estimated average annual heating fuel consumption for the nearby public buildings is 68,765 gallons. 3.0 ESTIMATED RECOVERED HEAT UTILIZATION A heat recovery utilization spreadsheet has been developed to estimate the recoverable heat based on monthly total electric power production, engine heat rates, building heating demand, washeteria loads, heating degree days, passive losses for power plant heat and piping, and arctic piping losses. Power generation data from AVEC for fiscal year 2011 is used in the spreadsheet. The estimated heat rejection rate for the power plant gensets, Caterpillar 3456 series with marine jackets, were used to estimate available recovered heat. Heating degree-days for Stebbins were utilized for this site. All arctic piping is assumed to be routed below grade. All power plant hydronic piping is assumed to be insulated with 2 in of insulation. The proposed conceptual generator plant design was used to estimate the heating load for the power plant, which includes the power house, an insulated storage module, and one living quarters module. The spreadsheet uses monthly heating degree-days to distribute annual fuel consumption by month. The washeteria commercial heating loads are field verified as approximately 80% of maximum utilization for 8 hours a day, 5 days a week. The end -user hourly heat load is compared to the hourly available heat from the power plant, less power plant heating loads and parasitic piping losses, and the net delivered heat to the end -user is determined. Following is a summary of annual fuel use and estimated heat utilization in equivalent gallons of fuel for each building: Facility Estimated Estimated Heat Annual Fuel Delivered W/ Intertie Use (Gallons) (Gallons) Old Water Treatment Plant 4,815 4,815 New Water Treatment Plant 5,318 5,318 Washeteria 7,452 2,653 Stebbins School 46,474 39,437 Clinic 2,353 2,353 Head Start Building 2,353 2,353 Total 68,765 56,929 4.0 HEAT RECOVERY SYSTEM DESCRIPTION AND OPERATION: The heat recovery system captures jacket water heat generated by the AVEC power plant that is typically rejected to the atmosphere by the radiators. The recovered heat is transferred via below -grade arctic piping to the end users. The objective is to reduce the consumption of expensive heating fuel by utilizing available recovered heat. Although heat recovery is an excellent method of reducing heating fuel costs, recovered heat is a supplementary heat source and it is imperative that the end -user facility heating systems are operational at all times. Hot engine coolant is piped through a plate heat exchanger located at the power plant. Heat is transferred from the engine coolant to the recovered heat loop without mixing the fluids. Controls at the power plant are used to prevent subcooling of the generator engines and reducing electric power production efficiency. The recovered heat fluid is pumped through buried insulated pipe to the end -user facilities, and is typically tied into the end -user heating system using a plate heat exchanger. 4.1 AVEC PLANT TIE-IN Because the AVEC plant is being designed for recovered heat, no modifications to the AVEC power plant cooling system are included or anticipated, except those required to connect the arctic piping to the power plant heat exchangers. All heat recovery piping will be insulated with a minimum of 2-in insulation and have an aluminum jacket where exposed to the weather. All valves will be either bronze ball valves or lug style butterfly valves with seals compatible with 50/50 glycol/water mixtures at 200F. Air vents, thermometers, pressure gauges, drain valves, and pressure relief valves will also be provided. 4.2 ARCTIC PIPING (Recovered Heat Loop) The proposed arctic piping is based on Rovanco's Rhinoflex preinsulated pipe design with a 4-in PEX-A carrier pipe, 1-in polyurethane foam insulation, and HDPE outer jacket. The piping will be buried approximately 2 ft deep and run from the AVEC plant within existing rights -of -way to the end -user buildings. Because multiple users are connected to the system, a variable speed pump located at the new power plant will circulate heating fluid to each user from the AVEC facility. When users are not actively consuming recovered heat, their systems will throttle down heating fluid flow to minimize power consumption. Electric charges for the circulation pump will be shared based on use of recovered heat. The recovered heat fluid will be a 50/50 Propylene Glycol/Water solution to provide freeze protection to the piping. 4.3 END -USER BUILDING TIE-INS End -user building tie-ins typically consist of brazed plate heat exchangers with motorized bypass valves to prevent back feeding heat to AVEC or other users. Plate heat exchangers located in the end -user mechanical rooms will be tied into the boiler return piping to preheat the boiler water prior to entering the boiler. Where required, a heat injection pump will be used to avoid introducing excessive pressure drop in the building heating system. The maximum anticipated delivered recovered heat supply temperature is about 190F. When there is insufficient recovered heat to meet the building heating load, the building heating system (boiler or heater) will fire and add heat. Off the shelf controls will lock out the recovered heat system when there is insufficient recovered heat available. Typical indoor piping will be type L copper tube with solder joints. Isolation valves will be solder end bronze ball valves or flanged butterfly valves. All piping will be insulated with a minimum of 1-in insulation with an all -service jacket. Flexibility will be provided where required for thermal expansion and differential movement. Air vents, thermometers, pressure gauges, drain valves, and pressure relief valves will also be provided. Each facility will also receive a BTU meter to provide recovered heat use totalization and instantaneous use. 4.4 PRIORITIZATION OF RECOVERED HEAT Recovered heat prioritization is accomplished by setting the minimum recovered heat temperature for each user, with successive load shedding as the recovered heat loop temperature falls. The user with the highest allowable recovered heat temperature will be removed from the system first. The user with the lowest allowable recovered heat temperature will be removed from the system last. The system will also provide freeze protection in the event a user's boiler system temperature falls below a minimum temperature, typically 50-100 degrees F. 4.5 RIGHTS -OF -WAY ISSUES There are no apparent conflicts with rights -of -ways for the arctic piping between the power plant and the end -user buildings, as the route is entirely within existing road rights -of -ways and on city, school and AVEC property. A Heat Sales/Right-of-Entry Agreement will be required between AVEC and the end users to define the parties' responsibilities, detail the cost of recovered heat, and authorize the connection to the power plant heat recovery equipment. 4.1 POTENTIAL RISKS AND UNKNOWNS The location of heating pumps and organization of the piping system is dependent on community, school and AVEC negotiating maintenance and rate structures. The cost estimate included in this feasibility study assumes that there will be two independent heating loops, one for the school and one for the community buildings. This is a conservative approach and a single district heating system is preferred. If a single heating system can be agreed upon, the benefit would be substantially better than reflected by the costs and fuel savings used in this feasibility study. The AVEC power plant may incorporate wind power but a final determination has not been made. Incorporation of wind turbines to reduce generator power consumption would most likely reduce the amount of recovered heat available, though if marine jacketed engines are used, there is still likely to be sufficient recovered heat available to provide a benefit for the facilities proposed in this study. 5.0 PRELIMINARY EQUIPMENT SELECTIONS The following initial equipment selections are sized and selected based on preliminary data and will require minor modifications to reflect final design. 5.1 Heat Exchangers Based on initial selected flow rates, brazed plate heat exchangers appear to be adequate for all locations.

All work at the power plant and WTP, along with design and construction management/administration for the complete project, is included in the Base Project cost. Incremental costs for arctic pipe, end -user building renovations, and overhead and freight are estimated individually for each of the other end -user buildings (refer to attached cost estimate). The estimated project cost is $1,243,000. Estimated fuel savings are: • 56,900 gallons ($237,700) for a simple payback of 5.2 years. Payback is based on a 2011 fuel price of $4.21/gallon. Funding for design and construction isn't expected before fall 2013, with construction occurring summer of 2014. With 2 years of escalation at 3%, the estimated project cost in 2014 is $1,319,000. 1600 1400 1200 1000 of x 800 m 600 400 200 0 Stebbins Recovered Heat Utilization W/ Intertie January February March April May June July Aug Sept Oct Nov Dec MONTH Washeteria Commercial Load (MBH) Head Start Heating Demand (MBH) New WTP Heating Demand (MBH) School load (MBH) Washeteria Seasonal Heating Demand (MBH) Clinic Heating Demand (MBH) Old WTP Heating Demand (MBH) Available Recovered Heat 9000 8000 7000 6000 5000 J Q 4000 3000 2000 1000 0 January Stebbins Recovered Heat Utilization W/ Intertie Gal avoided fuel use Gal fuel use 3 ti CA a 0 STEBBINS, ALASKA ANTHC RECOVERED HEAT STUDY SHEET LIST TABLE SHEET NUMBER SHEET TITLE 1 COVER 2 SITE PLAN 3 SYSTEM SCHEMATIC I 4 SYSTEM SCHEMATIC II 5 IDETAILS Alaska Native STEBBINS, AK Tribal Health Consortium ANTHC RECOVERED HEAT STUDY Division of Environmental Health and Engineering DATE: 07-16-2012 LAYOUT: COVER 1001 Bragaw 81rw1, Sulta 200 ANCHORAGE, ALASKA, 095011.3MO DRAWN BY: TH FILE NAME: WBB-G-STSITE (007) 7204000 CHECKED BY: WF SHEET 1 OF 5 USER: BCUSTER FILE PLOT DATE: HIM/2012 10:40 AN NEW WPT 1 ` FUTURE AVEC PLANT �(WBB-07-003) 1 J SlzgG� a flog ro w Q (A ' is ? o m 1 ',- $mm ■ 7 m a— Z Q 11 4" ARCTIC PIPE >-mm IBm m 0 7 m 7 ~2' ARCTIC PIPE - EXISTING HEAD START ♦ m M > 1 � 3 EXISTING WTP � F 2" ARCTIC PIPE cn v v r r} \ m x m mo EXISTING CLINIC 1 1 m_ i y 1 4' ARCTIC 2" ARCTIC = O 1 - PIPE PIPE o, 2" ARCTIC PIPE ' I f T EXISTINGf Z f^ WASHETERIA 1 4' ARCTIC PIPE 1 1hh�� n n7� Q ' ` II EXISTING ' !
