There is an existing heat recovery system in Ambler that used to provide recovered heat to the existing water plant and the school Teachers Quarters (old school). It is reported that the heat recovery system has been out of service for many years, due in part to failed heat exchangers and possibly failed arctic piping. For purposes of this report, it has been assumed that the existing heat recovery module at the power plant will be reused with minor modifications, including refurbishing or replacing the existing heat exchanger and installing new circulating pumps. 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 existing power plant cooling system and heat exchanger. It is anticipated that refinements in arctic pipe size and routing, pump and heat exchanger sizing, and other design elements will be required if the project progresses to final design. However, unless significant changes are required, the project cost is not expected to exceed the estimate contained herein. Available as-built information was obtained from the Alaska Village Electric Cooperative (AVEC) regarding the existing generators cooling system and heat loads of the AVEC power plant. Available heat load and design information were obtained from Larsen Consulting Group for the proposed water plant and washeteria. No site visits were made to confirm accuracy of information obtained. 2.0 OVERVIEW ANTHC is currently developing a new water plant and washeteria in Ambler. The purpose of this study is to provide an estimate of the heat that can be recovered from the jacket water of the AVEC power plant diesel engines and used to offset heating oil consumption at nearby public buildings. Useable recovered heat is quantified in gallons of heating fuel saved using a heating valwe of 134,000 BTU per gallon of #1 arctic diesel fuel and an overall boiler efficiency of 73%. This analysis only considers the potential to provide recovered heat to the new water plant and washeteria. The straight-line distance from the AVEC plant to the new water plant (adjacent to the existing water plant) is approximately 570-feet. The new washeteria will be located in a new addition to the existing City Office and is approximately 550-feet from the AVEC plant. Based on a Business Plan prepared by CRW Engineering Group, the estimated water plant and washeteria average annual heating fuel consumption is approximately 9,600-gallons and 3,700-gallons, respectively. It is estimated the existing City Office uses about 2,000-gallons of heating fuel, annually (fuel records were not provided). The combined annual fuel use of the washeteria/City Office is estimated at 5,700- galons/year, of which 2,800-gallons is for space heating and 2,900 gallons is for non- seasonal loads (showers, washing machines, and dryer make-up air hydronic heat). A spreadsheet has been developed to estimate the recoverable heat based on monthly total electric power production, engine heat rates, building heating demand, heating degree days, and passive losses for plant heat and piping. The spreadsheet utilizes assumed time-of-day variations for electric power production and heat demand. Power Cost Equalization data for fiscal year 2005 was used in the 1 Ambler Heat Recovery Analysis December 31, 2005 Alaska Energy and Engineering spreadsheet. The estimated heat rejection rate for a Detroit Diesel DDEC3 Series 60 was used for loads from OkW to 200kW, and a Cummins KTA19 at 1800 rpm was used for loads over 200kW. Heating degree-days for Kobuk were utilized for this site. All arctic piping is assumed to be routed below grade. All hydronic piping between modules is assumed to be 3" pipe with 2" of fiberglass insulation and installed above grade. Information provided by AVEC was used to estimate the heating load for the power plant, which includes two off-line generation modules, one control module, one wood-frame insulated crew quarters, and one wood-frame uninsulated storage shed. The uninsulated storage shed consumes excessive heat. In order to improve available recovered heat, for· this study it has been assumed the existing uninsulated shed will be replaced with an insulated connex brought in as part of the water ~lant I washeteria project. The insulated connex heat load is estimated to be about 1/5 the heat load of the existing shed. 3.0 OPTIONS FOR FACILTIES TO RECEIVE RECOVERED HEAT The spreadsheet uses monthly heating degree-days to distribute annual fuel consumption by month. The monthly heat load is then broken down by hour of the day using an estimated daily temperature variation. This results in a "peak" load for each month, which occurs in the middle of the night. This "peak" represents a daily maximum of the average load for that month, not the absolute peak load. Since a heat recovery system cannot necessarily meet the actual design peak heat load of a facility, the average is a good load to design to. To maximize utilization of available heat, the demand for heat should exceed the available heat. With arctic pipe to both facilities the "peak" heat available for delivery to the buildings is about 270 MBH. At this load a flow rate of approximately 50 GPM is required to limit the temperature drop in the piping loop to approximately 12F. Following is a summary of the heat demands, percentage of the total heat demand, and preliminary recommended flow rates for each facility: Facility Water Plant Wash/City Off. Total Building %of Total %of Heat Flow Demand Demand Available Avail. 346 MBH 69% 129% 35 GPM 157 MBH 31% 59% 15 GPM 503 MBH 100% 188% 50 GPM Heat Avail 189 MBH 81 MBH 270 MBH Based on this it appears there are three combinations of load that would work effectively to utilize most of the heat available: 1) the water plant only, 2) the washeteria/city office, and 3) water plant and washeteria/city office.

The recovered heat will be 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 a viable method of reducing heating fuel costs, a recovered heat system is a passive heat source and it is imperative that the end- user facility heating systems are operational at all times. Hot engine coolant is piped to a plate and frame heat exchanger located in the heat recovery module (HRM). Heat is transferred frorn the engine coolant to the recovered heat loop without mixing the fluids. The recovered heat fluid is pumped through arctic pipe to the end-user facilities, and is tied into the end-user heating systems using plate heat exchangers. AVEC PLANT TIE-IN: The existing AVEC cooling system is mostly 3" Victaulic piping and uses a Grundfos booster pump to circulate the engine coolant to the Heat Recovery Module and radiators. It is reported the existing radiator fan motors are single speed motors with on/off control provided by aquastats in the engine coolant return piping. No modifications to the AVEC cooling system are included, except modifications required in the Heat Recovery Module to connect the new heat exchanger to the cooling system using a pumped secondary loop. HEAT RECOVERY MODULE: The existing HRM is located adjacent to the Butler Building. It is a 9' x 15' insulated panel structure set on an 1-beam/treated heavy timber foundation. The HRM will be equipped with a plate heat exchanger, heat recovery loop circulating pumps, and arctic piping loop expansion tank. A new electric service entrance with meter is required to provide power to the ventilation system, circulating pumps, and module lighting. Stainless steel flex hoses are used at the piping connections to the recovered heat module to provide flexibility for differential movement between the HRM and AVEC power plant. It is also assumed that some minor improvements/repairs will be required to the HRM exterior. The piping inside the HRM and between the Butler Building and the HRM is Schedule 40 steel pipe. All piping will be insulated with a minimum of 1" insulation and have an aluminum jacket where exposed to the weather. All valves are lug style butterfly valves with seals that are compatible with 50150 glycol/water mixtures at 200F. Flexibility is provided where required for thermal expansion and differential movement. Air vents, thermometers, pressure gauges, drain valves and pressure relief valves are also provided. 3 Ambler Heat Recovery Analysis ARCTIC PIPING (Recovered Heat Loop): December 31, 2005 Alaska Energy and Engineering The proposed arctic piping is a pre-insulated buried piping system. The piping will be routed from the AVEC plant, southeast in the existing rights-of-way to the intersection of Dahl Avenue and Redstone Avenue, then southwest down Redstone Avenue to the new water plant. Enroute to the water plant, the arctic piping will branch off and continue southeast on Redstone Avenue Extension to the washeteria/City Office. The arctic piping system is a pre-insulated, bonded piping system. The pipes consist of Schedule 40 steel carrier pipe and HOPE outer jacket bonded to polyurethane foam insulation. The carrier piping will have all welded joints. The system comes complete with all fittings, tools and accessories required for assembly. The recovered heat fluid will be a 50/50 Propylene Glycol/Water solution to provide freeze protection to the piping. WATER PLANT and WASHETERIA/CITY OFFICE TIE-IN: Plate heat exchangers will be located in the water plant and washeteria/city office mechanical rooms, and tied into the boiler return piping to pre-heat the boiler water prior to entering the boiler. The maximum anticipated delivered recovered heat supply temperature is about 180F. If there is not sufficient recovered heat to meet the heating load, the boilers will fire and add heat. Piping will be type L copper pipe and supported as required . Isolation valves will be sweat style bronze ball valves or flanged butterfly valves . All piping will be insulated with a minimum of 1" 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. RIGHTS-OF-WAY ISSUES: There does not appear to be a conflict with right 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 and AVEC property . A Heat Sales Agreement and Right-of-Entry Agreement will be required from AVEC for the City to renovate the recovered heat module and to route the arctic piping on AVEC property. 5.0 SYSTEM CAPACITY A heat recovery simulation spreadsheet is used to estimate the potential recoverable heat based on monthly total electric power production, engine heat rates , building heating demand, heating degree days, and passive losses for plant heat and piping . The spreadsheet utilizes assumed time-of-day variations for electric power production and heat demand . All estimates are averages based on monthly totals and do not reflect peak heat available or utilized. 4 Ambler Heat Recovery Analysis 5.1 Heat Demand December 31, 2005 Alaska Energy and Engineering The heat demand for the water plant and washeteria was estimated based on data provided in the Ambler Business Plan prepared by CRW Engineering Group. The combined annual heating fuel consumption for the new water plant and new washeteria/city office is 15,300 gallons (water plant is 9,600 gallons and washeteria/city office is 5,700 gallons). Approximately 2,800 gallons is estimated to be non-seasonal (hot water for showers, washing machines and dryer preheat coils) and 12,500 gallons is seasonal. From the spreadsheet, the highest average heat 'demand is 343 MBH (Water Plant = 236 MBH, washeteria/office= 107 MBH) in February. This is based on heating degree days (-10F average ambient temperature). For 1% design day (-45F ambient temperature) the combined maximum heat load is estimated to be 503 MBH (Water Plant = 346 MBH, washeteria/office = 157 MBH), not including peak domestic hot water load. 5.2 Heat Available The AVEC power plant has two primary units - a Detroit Diesel Series 60 DDEC3 rated 314 kW at 1800 rpm and a Cummins KTA19 rated 397 kW at 1800 rpm. The Series 60 ran 6585 hours and the KTA19 ran 21 '97 hour in 2004. It is assumed the Series 60 runs when loads are below about 200kW, and the KTA19 runs when loads are greater than 200kW. The Series 60 has an air-cooled aftercooler, and the jacket water heat rate is approximately 1,360 BTUH per kW electric load. The KTA19 has a jacketwater aftercooler, which results in a heat rate of about 2,255 BTUH per kW electric load. From the spreadsheet, the highest average delivered heat is 268 MBH -based on average power production. The peak electric load in FY2005 was 302 kW, occurring in January 2005. Winter daily peak loads are estimated to be approximately 280 kW. The heat output from the KTA19 at 280 kW is approximately 630 MBH. Fixed losses for arctic piping and plant piping are estimated at 68 MBH and variable losses for plant heat and exterior piping are estimated at 142 MBH on a peak design day. Net peak heat available is approximately 420 MBH. Since the peak heat demand exceeds the heat available, the heat recovery system should be designed based on heat available. 5.3 Flow Rates As indicated in Section 2.0, an arctic pipe flow rate of 50 GPM was selected so the heat recovery loop temperature differential would not exceed about 12F at average winter heat output. However, since the KTA19 . operates much of the cold winter months, the heat recovery system should be designed to utilize the higher available heat from the KTA19. For 420 MBH at 50 GPM, the delta-Twill be 19F-which is a reasonable temperature drop for a boiler heating system. It is expected that the washeteria heat demand will be greater during "daytime" hours -due to the high domestic hot water heat load, whereas the water plant heat load will be greatest late at night. In order to regulate the heat recovery loop flow rate to each end-user, it is proposed to utilize a thermostatically operated regulating (throttling) valve in the heat recovery loop at each end-user heat exchanger. These valves will throttle the recovered heat flow through the end-user heat exchanger based on the building return temperature. As the return temperature from the building to the heat exchanger increases, the recovered heat flow from the power plant will be reduced. In this way, when one end-user heat load is low, more of the available heat (flow) will go to the other end-user. Additionally, a variable speed drive will be used to control the heat recovery loop flow rate in order 5 Ambler Heat Recovery Analysis December 31 , 2005 Alaska Energy and Engineering to maximize the heat delivered when the KTA19 is online and to help prevent overcooling the engine cooling system when the Series 60 is online. The Series 60 coolant flow is about 80 GPM, and the KTA19 coolant flow is about 145 GPM at rated load. To avoid additional external head on the generator cooling system pumps, a secondary pumped loop will be used off of the jacket water cooling loop to the radiators. The secondary pumped flow needs to be less than 80 GPM to avoid dilution of hot coolant when the Series 60 is on-line so will set the secondary loop flow equal to arctic pipe flow rate of 50 GPM. 5.0 EQUIPMENT SELECTIONS 5.1 Heat Exchangers Based on initial selected flow rates, brazed plate heat exchangers will be adequate for all locations. The total end-user heat exchanger capacity is greater than the power plant heat exchanger capacity, to benefit from the increased flow resulting from use of the thermostatically operated regulating valves. Initial heat exchanger selections are as follows. HX-1: (Power Plant) Ameridex SL 140TL-LL-80 or equal. 400 MBH capacity. Primary: 50 GPM 190F EWT (50% ethylene glycol), 1.0 PSI max WPD Secondary: 50 GPM 180F LWT (50% propylene glycol) 1.0 PSI max WPD HX-2: (Water Plant) Ameridex SL 140TL-LL-80 or equal. 350 MBH capacity.

Primary: 22 GPM 180F EWT (50% propylene glycol), 1.0 PSI max WPD Secondary: 20 GPM 175F LWT (50% propylene glycol) 1.0 PSI max WPD 5.2 Arctic Pipe Sizing The length of heat recovery loop piping between the power plant and water plant is approximately 1500'. The arctic pipe is sized so the pressure drop is less than 1' head per 100' to limit pumping energy. Using 3" piping, the unit pressure drop is approximately 0.67' per 1 00' at 50 GPM. 5.3 Circulating Pumps P-HR1: HX-1 Primary circuit off engine coolant loop Flow= 50 GPM, Head= 2' (HX) + 4' (piping)= 6' Select: Grundfos UPS 40-40, 50 GPM at 6' TDH, 1/3 HP, Speed 3 P-HR2: Heat recovery loop to water plant Flow= 50 GPM, Head= 2' (HX-1) +2' (HX-2) + 20' (piping)= 24' Select: Grundfos TP40-80/2, 50 GPM at 24' TDH, 3/4 HP, variable speed motor 5.4 Expansion Tank See spreadsheet for expansion calculations. Total heat recovery loop volume is estimated at 950 gallons. Pressure relief at the power plant heat exchanger will be 50 PSIG, so will size tank to limit operating pressure to 90% of maximum (45 PSIG). High point of system approximately 16' above base of expansion tank so 7 PSIG minimum is pressure required at the expansion tank to keep heat loop system 6 Ambler Heat Recovery Analysis December 31, 2005 Alaska Energy and Engineering pressure positive. Will set tank pre-charge to 10 PSIG to provide 3 PSIG positive pressure at high point. 12.1 PSIG fill pressure required at 40F to maintain 10 PSIG at OF. Will fill system cold to 12 PSIG to provide minimum 2 PSIG pressure above expansion tank pre-charge and 8 gallons of glycol in the tank at 40F, so the tank will not go dry at OF. ET-1: Minimum requirements 97.5 gallon tank and 67.0 gallon acceptance Select: Amtrol L300, 105 gallon tank and 9~.5 gallon acceptance 6.0 CONCLUSIONS AND RECOMMENDATIONS The project has a relatively high construction cost due to the distance between the power plant and end-user building(s). However, based on a cost of fuel of $4.15/gallon (from the Business Plan), the simple payback for all three options are about 10 years, or less. · Estimated Project Cost And Savings: Facility Served Water Plant Only Washeteria/City Office Both Buildings Est'd Fuel Savings 7,671 Gal 5,689 Gal* 8.864 Gal 7 Value at $4.15/gal $31,835 $23,610 $36,786 Est'd Const Simple Cost Payback $244,318 7.8 yrs $243,743 10.3 yrs $305.248 8.3 yrs c:J ooo nnn ----- \ DRAWN B'f: SJS SC.U: 1"=80' stat~of Alaako AEA RECOVERED HEAT STUDY o. rbJI• nt ot eo d Ec 1-=:::---:-:-:-:-:-==-:-=-=-::-:-::=:=-:---:-:::-:-=--:-:-:--:-------Fn:=DESICNEll~;:.B'f:...:::: SJ::.::_S -1f..;"";:;;=ro~12/~30:!:/;:05~ * * **po w• mAIDEAi AEAconomlc Oemopment 111\..E: AMBLER RECOVERED HEAT SYSTEM ru: NAME SHEET or Rural Energy Group ~ALASKA S H 1 113 w .. t NorlNm Ughtl B"'d. , -ENEROY AUTHORrtY SITE PLAN c!c DETAILS AMBLER.DWG 2 '* -09·· ........
