AEA13-006 Grant Application Page 6 of 20 7/3//2012 Renewable Energy Fund Round 6 Grant Application 4111111111111E)ENERGYAUTHORRY 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 of the power plant engines. The heat available from the power plant significantly reduces that required by the water treatment plant most of the year, as indicated by the attached 2012 Heat Recovery Feasibility Study. The only realistic alternative to utilizing the recovered heat is to continue to burn over 21,000 gallons of fuel oil to provide the heat required by the water treatment plant. More specifics are contained in the attached 2012 Heat Recovery Feasibility Study. 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 the number, size, aRe, efficiency, and type of generation. 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, 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 lead power plant genset, a Detroit Diesel Series 60 DDEC4 (with marine jacket installed), is used to estimate available recovered heat. Heating degree-days for Noorvik were utilized for this site. All arctic piping is assumed to be routed above grade. 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 water treatment plant building is hydronically heated. An energy audit of the facility performed in 2011 estimated annual fuel consumption of 21,300 gallons/year. The existing power plant was not designed for heat recovery and must be retrofitted. 4.2.3 Existing Energy Market Discuss existing energy use and its market. Discuss impacts your project may have on energy customers. AEA13-006 Grant Application Page 7 of 20 7/3//2012 Renewable Energy Fund Round 6 _ MM_. - Grant Application i4MM9___-EN_E_RGYALJTH0RrrY All heating oil must be barged in during the summer months. The impact of this project will be to reduce the overall use of oil by approximately 18,600 gallons per year. While this reduction will not change the price of oil in Noorvik, it will significantly reduce the community's consumption of oil, replacing that consumption with jacket heat from the diesel engines. 4.3 Proposed System Inciude information necessary to describe the system you are intending to develop and 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 ■ Deliveri methods address 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 above -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 sub -cooling of the generator engines and associated reduction of 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 A marine jacket will be added to the lead power plant generator. All generator cooling piping will be insulated with a minimum of 1.5-in rubber foam 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. Additional controls will be added, including a BTU meter and motorized bypass valve for coolant temperature control. ARCTIC PIPING (Recovered Heat Loop) The proposed arctic piping is based on ANTHC's standard arctic pipe design with a 3-in fiber reinforced polypropylene carrier pipe (Aquatherm Climatherm SDR11), 4-in polyurethane foam insulation, and aluminum outer jacket. The wing will be supported from the ground AEA13-006 Grant Application Page 8 of 20 7/3//2012 Renewable Energy Fund Round 6 •■© Grant Application GM11111111111DENERGY AUTHORfTY surface or helical piers where the ground isn't sufficiently stable. The heat recovery piping will run from the power plant alongside the road to the to the end -user building. Circulation pumps located at the water treatment plant building will circulate heating fluid from the AVEC facility. When the water treatment plant is not actively consuming recovered heat, the system will throttle down heating fluid flow to minimize power consumption. 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 a heat injection pump to prevent back feeding heat to AVEC or other users. Plate heat exchangers located in the end -user mechanical room will be tied into the boiler return piping to preheat the boiler water prior to entering the boiler. 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. The end -user facility will also receive a BTU meter to provide recovered heat use totalization and instantaneous use. 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 building, as the route is entirely within existing road rights -of -way and on city and AVEC property. 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 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. No other permits are anticipated for this heat recovery project.

AEA137006 Grant Application Page 13 of 20 7/3//2012 Renewable Energy Fund Round 6 Grant Application SECTION 5— PROJECT BENEFIT INOW-) ENERGY AUTHORITY 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 • 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 18,600 gallons of the 21,000 gallons of fuel used at the water treatment plant last year. The cost of the fuel is $4.58 per gallon (summer 2012). The annual cost of fuel displaced for the water treatment plant therefore equals $85,188. Over the 30-year life of the heat recovery system, the savings will be $2,555,640 in today's dollars. Assuming a heat sales agreement specifying a heat sales rate of 30% of displaced oil, the facilities will save $1,788,948 and AVEC will receive new revenue of $766,692 over the 20 years. There are no other known incentives or revenue streams that will result from this project. The benefits of this project to the community include a reduction in the amount of fuel required by the community, a much more efficient use of the recovered engine heat, and a direct benefit to each community member due to the lower cost to produce, store, and deliver water. SECTION f-- 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 ally 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 water treatment plant by reducing its operating cost by $2,555,640 over the 30-year life of the project. The minimal maintenance and operating cost can be funded out of its revenue stream and out of its savings over the 30-year life of the project. The existing boilers will be maintained in the water treatment plant as a backup to the heat recovery system. The City of Noorvik is committed to meeting all reporting requirements over the entire length of the reporting period.

The total annual heating fuel used by the WTP is verified by the community as approximately 21,000 gallons. The estimated fuel savings realized by implementing a heat recovery system is approximately 18,600 gallons. The estimated cost for the heat recovery project is $986,000. The simple payback based on a fuel cost of $4.58/gallon is 11.6 years. 1.0 INTRODUCTION The Alaska Native Tribal Health Consortium (ANTHC) reviewed the feasibility of providing recovered heat from the existing AVEC power plant to the existing WTP building in Noorvik. ANTHC also developed a budgetary project cost estimate based on Force Account Construction, including Engineering and Construction Administration. The existing WTP building provides heat to the circulating water lines and heat to one of the water storage tank (WST). 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. This building is estimated to consume approximately 21,000 gallons of diesel per year. Significant work will be required at the power plant, including installation of 3 heat exchangers, insulating existing piping and new controls. This is included in the cost estimate. In addition, AVEC requires a heat sales agreement which will result in approximately 30% of the fuel savings to be paid to AVEC. 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 information was obtained from AVEC regarding the 2011 power plant electrical loads. End -user annual fuel use was obtained fr6rh-a variety of sources, including the City, Alaska Rural Utility Cooperative (ARU9), and engineering estimates. Reported fuel consumption was used to validate engineering estimates. Site visits were made to the existing WTP and washeteria to cor1firm 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 fo offset heating oil consumption at the nearby public buildings. Useable recovered heat is quantified in gallghs 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 1300-foot radius of the AVEC power plant. This analysis evaluates the potential to provide recovered heat to the nearby Water treatment plant, but the city office building and school are also within range. The estimated average annual heating fuel consumption for the nearby WTP is 21,000 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. 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 lead power plant genset, a Detroit Diesel Series 60 DDEC4 (with marine jacket installed), is used to estimate available recovered heat. Heating degree-days for Noorvik were utilized for this site. All arctic piping is assumed to be routed above grade. The spreadsheet uses monthly heating degree-days to distribute annual fuel consumption by month. 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 Use Delivered (Gallons) (Gallons) Water Treatment Plant 21,300 18,600 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 above -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 sub -cooling 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 A marine jacket will be added to the lead power plant generator. All generator cooling piping will be insulated with a minimum of 1.5-in rubber foam 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. Additional controls will be added, including a BTU meter and motorized bypass valve for coolant temperature control. 4.2 ARCTIC PIPING (Recovered Heat Loop) The proposed arctic piping is based on ANTHC's standard arctic pipe design with a 3-in fiber reinforced polypropylene carrier pipe (Aquatherm Climatherm SDR11), 4-in polyurethane foam insulation, and aluminum outer jacket. The piping will be supported on sleepers on the ground surface or helical piers where the ground isn't sufficiently stable. The heat recovery piping will run from the power plant alongside the road to the to the end -user building. Circulation pumps located at the WTP building will circulate heating fluid from the AVEC facility. When the WTP is not actively consuming recovered heat, the system will throttle down heating fluid flow to minimize power consumption. 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 a heat injection pump to prevent back feeding heat to AVEC or other users. Plate heat exchangers located in the end -user mechanical room will be tied into the boiler return piping to preheat the boiler water prior to entering the boiler. 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. The end user facility will also receive a BTU meter to provide recovered heat use totalization and instantaneous use. 4.4 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 building, as the route is entirely within existing road rights -of -ways 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. 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. Initial heat exchanger selections are as follows. HX-1: (WTP). 400 MBH capacity Primary: 45 GPM 19OF EWT (50% ethylene glycol), 1.0 PSI max WPD Secondary: 45 GPM 185F LWT (50% propylene glycol) 1.0 PSI max WPD HX-2, HX-3, HX-4: (AVEC Station 1). 400 MBH capacity. Primary: 45 GPM 195F EWT (50% propylene glycol), 1.0 PSI max WPD Secondary: 45 GPM 185F LWT (50% propylene glycol) 1.0 PSI max WPD 5.2 Arctic Piping The length of heat recovery loop piping between the power plant and most distant facility is approximately 3600ft, round trip. The arctic piping utilizes 3-in carrier pipe to minimize pressure drop and reduce pumping energy. The pipe itself consists of a 3-in fiber reinforced polypropylene carrier pipe, 4" of polyurethane insulation and an aluminum outer jacket. The specified product is durable enough for direct exposure to the weather and resistant to crushing. 5.3 Circulating Pumps P-HR1: Heat recovery loop pump at Water Treatment Plant Flow = 45 GPM, Head = 45 ft Initial Selection: Grundfos TPE with integrated VFD. P-HR2: Heat injection pump in combined utility building. Flow = 45 GPM, Head = 15 ft Initial Selection: Grundfos 50-60F. 5.4 Expansion Tank Total heat recovery loop volume is approximately 4800 gallons. Pressure relief at the heat exchangers will be 45 PSIG and the maximum normal operating pressure will be 40 PSIG. ET-1: System requirements: 700 gallon tank and 360 gallon acceptance. Use (2) AMTROL ST-455 located at the water plant. 5.5 GLYCOL MAKEUP An existing glycol make-up system at the water treatment plant will provide make-up to the system. 5.6 CONTROLS Heat recovery system will use an off the shelf differential temperature controller to start/stop a heat injection pump. Control will provide load shedding, freeze protection, and prevent backfeeding of boiler heat into heat recovery system. In addition, A BTU meter will be provided, displaying instantaneous temperatures and heat transfer, as well as totalizing BTUs used. Differential Controllers: 1 required Tekmar Model 155 differential temperature control BTU Meters: BTU-1 WTP Building: KEP BTU meter with 2" magnetic flow meter and matching temperature elements. 6.0 CONCLUSIONS AND RECOMMENDATIONS Estimated construction costs were determined based on prior recent heat recovery project experience, and include materials, equipment, freight, labor, design, construction management, and startup and testing. 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 for is $986,000. Estimated fuel savings are about 14,500 gallons. Using a 2011 fuel price of $4.50/gallon results in estimated community savings of $66,300 for a simple payback of 11.6 years. 500 F! 450 400 350 300 z x 250 Co 200 150 100 50 0 Noorvik Recovered Heat
