DRAFT 1/5/2014 for REFAC Review 2 of 76 Alaska Renewable Energy Fund: Round 7 - DRAFT 1006 NEA Stack Heat to Power Project Naknek Electric Association, Inc. Feasibility Design ConstructionProposer: Proposed Project Phase: App # Heat RecoveryResource: Applicant Type:Utility Bristol BayEnergy Region: Heat Application Devany PlentovichProgram Manager: Project Description The Cooperative faces an urgent need to stabilize and lower the cost of electricity to consumers. Improving fuel efficiency in its diesel generation facility NEA will install two highly efficient waste heat to power (WH2P) systems onto existing diesel-fueled reciprocating engines to increase efficiency and reduce costs. The selected WH2P systems utilize supercritical carbon dioxide (sCO2) as the working fluid for converting stack heat to electrical power without additional fuel consumption or emissions. The stack heat to power project is scheduled for completion fifteen (15) months from the authorization to proceed date, and the proposed budget supports all design, fabrication, installation, commissioning, training, management, and reporting tasks for a $1.94 million investment. AEA Review Comments and Recommendation The Naknek Electrical Association is proposing the feasibility, design, and construction of two Echogen stack heat recovery to power systems on the utility’s diesel generators. The estimated power generation is 2.3MM kWh annually. Echogen is proposing a modified Organic Rankine Cycle engine with supercritical carbon dioxide as the working fluid. The stated thermal efficiency is approximately 20%. While AEA is interested in this concept, the modified Organic Rankine Cycle is still an emerging technology. This application would be better suited for the Emerging Energy Technology Program. AEA recommends the Naknek Electrical Association power systems be evaluated and included in AEA’s priority ranking list for Rural Power Systems Upgrade program assistance. Additionally, AEA encourages NEA to work directly with AEA staff to address the community energy needs. Please contact AEA’s energy planning staff for direct assistance. No funding recommended.

The community of Juneau recently received a $7 million grant from Alaska Department of Commerce, Community and Economic Development to construct the new library in Juneau’s Mendenhall Valley. The City & Borough of Juneau Assembly is interested in reducing the carbon footprint of Juneau and reducing the operating costs of their facilities. The use of a geothermal HVAC system rather than traditional oil-fired boilers and chillers provides an opportunity to achieve both goals of the City & Borough of Juneau and to expand the use of renewable energy in city facilities. AEA Review Comments and Recommendation The City and Borough of Juneau proposes to install a ground source heat pump system to heat the new Mendenhall Library. While Juneau offers a favorable climate for ground source heat pump systems, the significant cost of vertical well loop field construction has a high impact on project economics. As proposed, the Mendenhall Library heat pump system would incur high construction costs but use well below 20% of the system’s total capacity on an annual basis. Because of this, the proposed system for the Mendenhall Library does not compare favorably on an economic basis to the fuel oil system used as a base case. A similar system was proposed in REF Round 6; after consultation with the applicant, AEA recommended funding for a smaller GSHP system that relied on a supplemental oil fuel boiler for peak demand. The project did not ultimately receive funding. This suggested design was not pursued in the current application; although the proposed design is less economically attractive than it might have been, it remains technically feasible. Full funding recommended.

The fuel oil savings to the community water plant is projected to be 1 ,900 gallons of heating oil per year. For more detailed information, see the attached Chuathbaluk, Alaska 2013 Heat Recovery Feasibility Study. AEA Review Comments and Recommendation The Alaska Native Tribal Health Consortium and the City of Chuathbaluk are proposing to design and construct a recovered heat system from the existing power plant for heating the water system. Existing unused heat trace piping will be used to transfer the heat from the power plant to the water treatment plant. Although the Preliminary Heat Recovery Assessment was completed in September of 2013 and showed sufficient excess heat to support this project, it did not address the energy required to pump the water through relatively small diameter pipe and long distances. We are concerned that the energy required to pump the heated water from the power plant to the water treatment plant through the unused heat trace piping will consume more energy that the estimated savings of the project, creating an additional financial burden on the community. Additional information was requested on pumping costs but was never received. Not recommended for funding.

The building included for the Nenana Native Council is the Youth Educational Resource Center (YERC), which houses the Early Learning, Head Start, and Youth Center programs. The school district buildings included in the project are the Nenana City Public School, the Administration Building, the Warehouse/Vocational Education Building, and the Nenana Student Living Center. Though the Nenana Student Living Center is located approximately six blocks from the Nenana City Public School, the “Pre-Feasibility Assessment” states, “The additional energy saved by connecting several buildings together offsets the significant additional cost of underground piping and pumping costs. . . . Even with the significant piping costs, the extra pumping energy, and the extra wood fuel needed to offset the heat loss of the long pipe runs, this option remains the strongest relative to other options.” (p. 2 & 3 of 13) AEA Review Comments and Recommendation The Nenana City School District in Nenana, AK (Interior Alaska) requests funding for engineering design to build a district wide heating system for the following buildings: Nenana City School; Administration Building; Warehouse; Nenana Student Living Center; Nenana Native Council Day Care; City Water Plant; City Fire Department. The project is estimated to displace 87,800 gallons of fuel/year and has the potential to save the Nenana City School District in excess of $3,516,725 over the life of the project. This project is an example of good collaboration efforts among community organizations in an effort to provide low cost heating to the entire community of Nenana. Also the local community appears to be supportive of a district biomass heating project. AEA will work with the grantee to ensure that building energy efficiency is addressed in conjunction with this project.

DNR/DGGS Geohazards Comments All projects proposing the development of permanent structures should conduct a geotechnical site survey to determine the potential detrimental effects from natural hazards such as flooding, earthquakes, active faults, tsunamis, landslides, volcanoes, liquefaction, subsidence, storm surges, ice movement, snow avalanches, and erosion, and incorporate appropriate measures to mitigate the risks. Projects may be required to perform a geohazards site survey as a condition of receiving construction permits, depending on location of proposed site. DNR/DGGS Feasibility Comments DNR/DOF Feasibility Comments This project was reviewed for the Round 6 application period. No changes for wood requirement have been made in the current application (approximately 1,037 green tons 30% moisture content). The approximately 20-75 acres of timber per year required for this project, depending on timber harvest equipment configuration, would be quite sustainable for this area of the Tanana Valley.

The system will use dried wood fuel from the AEA funded dryer at Viking Lumber and benefit Viking by expanding the market base for dry wood fuel. The installed boilers would heat the 52,219 square foot high school using wood chips generated by operations at a local lumber mill. Feedstock for the mill and the resulting wood chips comes from timber logged from the nearby Tongass National Forest, Southeast Alaska State Forest, Alaska Native Corporation lands and other private lands. The project is similar in scope for the Craig Wood Fired Boiler and will share an existing contract to provide wood chips for the boiler. A Preliminary Feasibility Assessment for Conversion from Fossil Fuel Oil to Wood Heating for the Craig High School, Craig, Alaska was prepared for the Craig city School District by Robert Deering, Biomass Program Manager, USDA Forest Service, Tongass National Forest. A Copy of the study is attached to this application. An Energy Audit has been completed for the facility and is attached to this application. AEA Review Comments and Recommendation The Craig High School District in Craig, AK requests funding for engineering design and construction to build a low emission,high efficiency, and 3rd party tested biomass heating system for the Craig High School. The project is estimated to displace 19,459 gallons of fuel/year and has the potential to save the Craig School District in excess fuel cost savings of $2.1 million - $2.6 million over 20 years. This project is an example of good collaboration efforts among community organizations in an effort to provide low cost heating to the entire community of Craig and surrounding communities. Also the local community appears to be supportive of a district biomass heating project. AEA will work with the grantee to ensure that building energy efficiency is addressed in conjunction with this project. AEA recommends partial funding of design and permitting to allow the Craig High School to make an informed decision about pursing biomass as a heating option.

DNR/DGGS Feasibility Comments DNR/DOF Feasibility Comments This project is for design and construction of a new biomass boiler to heat the Craig High School. The boiler will be in addition to one that is currently operational and is heating the elementary and middle schools. The system will use dried wood fuel from the AEA funded drier at Viking Lumber. Wood supply for this project appears sustainable because Viking’s raw wood supply originates from a variety of land owners including the Tongass National Forest, Southeast State Forest and village corporation lands. The overall annual demand of the new and old boiler installations will only consume about 2% of the annual production of biomass at the mill.

While the HVAC must be replaced, the base case assumptions include the retaining of the current fuel oil boilers, the use of natural cooling supplemented with air-cooled compressor unit, separate conventional variable air volume ventilation systems for the museum, auditorium, and office units, and thermal upgrades that would decrease energy consumption by 20% relative to the current structure. The six air-to-water heat pump units would be situated outdoors and a variable refrigerant flow (VRF) system would pipe refrigerant to the 16 indoor fan coils to provide heating or cooling to the building. Ventilation air would be supplied by energy recovery ventilators that transfer heat from the exhaust or relief air to the fresh air being supplied to each fan coil unit. The outdoor heat pump assembly would be housed within a louvered enclosure to protect the equipment and lessen noise issues. Backup heat would be supplied by electric heating coils with a total capacity of 930 MBH. This proposal is a direct result of the attached Renewable Energy Feasibility Analysis, which was completed July 2012 under a RE Fund Round 3 grant. See Attachment 1. AEA Review Comments and Recommendation The City and Borough of Sitka proposes to install an air source heat pump system as a part of an extensive renovation of Centennial Hall. Although air source heat pump performance in southeast Alaska is not well documented, the economics of the project appear favorable under a range of different conservative assumptions. The planned renovation offers a good opportunity to replace the existing fuel oil boilers with an air source heat pump system and could provide valuable data of the performance of newer air source heat pump models in southeast Alaska.

The existing oil fired boilers have reached the end of their useful life and need to be replaced. The effluent, with an average temperature nearing 50°F, passes by the boiler room, easing the integration of the heat resource. The effluent from the wastewater treatment plant would pass through an in-line screen prior to going through a stainless steel plate-and-frame heat exchanger; an antifreeze solution would be heated by the effluent on the other side of the heat exchanger. The refrigerant from the 868 MBH water-to-water heat pump unit would be heated by the antifreeze solution in the evaporator. Using the vapor compression cycle, the heat pump would then "lift" this heat to 115°F during the compression cycle, and then transfer that heat to the condenser loop to supply heating appliances. 220 gallons per minute of effluent will be required to provide sufficient heat to the evaporator under design load conditions. A variable frequency drive on the existing recycled effluent pump will provide the correct flow of effluent to the heat exchanger under varied heat load conditions. As the Wastewater Treatment Plant is currently designed for 180°F in its heating system, the air handlers, unit heaters, cabinet unit heaters, and baseboard heaters would need to be replaced to increase the amount of surface area of heating coils to compensate for the 115F temperature hydronic water supplied by the heat pump system. Backup heat would be supplied by a new 955 MBH fuel oil boiler in conjunction with a storage tank. This proposal is a direct result of the attached Renewable Energy Feasibility Analysis completed by Alaska Energy Engineering, LLC in July 2012 under a RE Fund Round 3 grant. See Attachment 1. AEA Review Comments and Recommendation The City and Borough of Sitka proposes to install an effluent source heat pump system in the waste water treatment facility to decrease reliance on the fuel oil boiler. The proposal to use waste water effluent as a source for a heat pump system is a compelling use of an otherwise unused heat source, and could serve as a model for similar systems in other parts of the state. The high temperature and availability of effluent would result in a higher heat pump COP than seen in ground or sea water source installations. Unfortunately, a combination of high anticipated capital costs and low overall annual heat demand make the economics of the project less beneficial than in a location with year round heating needs. If possible, AEA suggests incorporating other heating loads into the system in order to take full advantage of the proposed system’s capacity which would improve the project economics.

DNR/DGGS Feasibility Comments DNR/DOF Feasibility Comments This project is for design and construction of a wood chip fired boiler at Tazlina. The system would be used to heat four collocated community public buildings. The supply of chips is expected to come from NRCS funded moose habitat clearings occurring on Ahtna lands and on BIA funded hazard fuel breaks. Roughly 116 green tons will be required annually. Based on state lands inventory data collected in the Glennallen area, roughly 30 green tons per acre of above ground biomass is present on the forest lands. The amount of raw material required for Tazlina would be quite sustainable if harvested in the Copper River Basin area. In the event these publicly funded projects are unable to provide biomass, Tazlina is willing to procure the raw material at an estimated cost of $90.00/green ton. They would also be willing to purchase fuel wood locally at $250-300 per cord and then chip prior to burning. At a fuel price of $90.00/ green ton, the annual fuel purchase price would be $10,400. This amount is significantly lower than the annual cost ($39,582) of 8,078 gallons of fuel oil. One good aspect of this proposal is that although ease of stoking is achieved by a chip system, Tazlina expects to use information from the Mentasta village use of a similar system for trial. If it does not perform adequately for Mentasta then Tazlina may default to a more standard Garn solid wool boiler. A commitment from Ahtna to provide the moose clearing residue at no cost other than chipping was stated in the application with attachment. The attached letter was not available for this review.

This is well within the realm of sustainability as the Tongass National Forest is stated to have an annual resource availability of 60-70 million board feet. It is not clear what firewood vendors are in place to supply this volume but the project proposal states that the Howard Valentine School in Coffman Cove purchased 200 cords from a commercial vendor. If vendors are available to supply the raw material, and the Forest Service offers up volume, then there should be sufficient biomass available for the project.

We anticipate the result of greatly reduced heating costs for the schools and associated buildings. Thorne Bay School received a grant in 2009 to install two Garn wood fired boiler units, and while the system has been operating, it has proven too small for the job. The units currently in use, (proto-types), can easily be moved with a forklift, so part of the proposal is to install them at two other school sites, Whale Pass and Hollis Schools. In order to heat the facility in Thorne Bay which includes a teacher housing unit and a hydroponic greenhouse, the current system would be replaced with 2 Garn 3200's, and a structure built to house the boilers. Very little reconstruction would be necessary in Thorne Bay due to the portability of the current Garn Pacs. In Whale Pass and Hollis, structures would be built to house the boilers. Wood storage buildings will also be constructed. At Naukati School we would install a wood fired boiler and build the housing for it as well as for wood storage. The Naukati School is the same size as Howard Valentine School, Coffman Cove, in our district, where we have an operating Garn system. Naukati will be modeled after the Coffman Cove set-up. Money saved on the fuel costs will be re-invested in the school, resulting in more direct service to our students.

DNR/DGGS Feasibility Comments DNR/DOF Feasibility Comments This project submitted by the Haines Borough seeks funding to conduct construction of ten wood pellet boilers and storage silos in several Borough-owned buildings. It is expected that the pellet boilers will displace 80,000 gallons of fuel oil annually for a savings of $59,000. This is based on a pellet delivered price of between $300 and $360 per ton and consuming about 695 tons of pellets. The borough is working with Sealaska and other potential pellet suppliers to provide a secure, long-term supply of pellets. Pellets are sourced from Washington and delivered by Sealaska of Juneau. This project appears to be well thought out and likely to be successful given the fact that the Sealaska Corporation already is utilizing a significant amount of pellets with a proven fuel delivery system. The proposal also mentions that Chilkoot Indian Association in Haines is considering the construction of a pellet plant in Haines. If this materializes, it could provide another source of pellets to the borough.

The energy to power the system will come from excess electricity available from the recently completed Chuniixsax Creek hydroelectric plant. The existing hydro-electric controls will be reprogrammed to support the dispatchable system. Each installation will include replacement of the existing electric meter with a duplex meter base to meter dispatched energy separate from building power; a new dispatchable energy panel and controller; an electric boiler; unit heaters or baseboards; wiring; and hydronic heating connections. AEA Review Comments and Recommendation City of Atka requests $114,965 in grant funds to install dispatchable electrical heating systems in public buildings to utilize excess hydroelectric generation from the Chuniisax Creek Hydroelectric Project. The project is expected to displace 8,300 gallons of diesel fuel annually. The City completed permitting and design under a Round 3 REF grant (#7030001) for $80,000. AEA has the following concerns: The environmental report did not investigate the potential for encountering lead based paint and asbestos containing materials in the installation of the new heating equipment in the older buildings to be served. This oversight may add risk to the project, since, if found, these would require specialty subcontractors to remediate. Also, it appears the powerhouse load bank will still be in use for frequency regulation, which will continue to “waste” electricity. AEA recommends making energy efficiency improvements to the buildings that will receive hydro heat, further enhancing the benefit of the hydro energy. Recommend full funding.

Seldovia House Senior Housing Complex. Seldovia House is an 18-unit housing complex serving low income senior citizens living in Seldovia. The total annual cost for heating oil for 2012 heating season (Jan 2012-Dec 2012) was $56,461. A field of ten vertical wells, 6” diameter x 300 ft. depth, will be located under the existing parking area and will serve as the heat source. A manifold loop of buried HDPE piping with methanol/water mixture will connect the wells to two high efficiency water to water heat pumps installed in the existing mechanical room. One of the existing heating oil boilers will be replaced by the two new heat pumps. On the load (hot) side of the heat pumps, buffer tanks will be heated from 130F to 145F, these will in turn supply heat to both hydronic space heating and domestic hot water. A heat pump/boiler controller will integrate the heating oil boiler such that supplemental heat will be provided when the heat pump capacity is exceeded on cold winter days. The goal of the ground source heat pump project is to displace approximately 75% of the heating oil currently used annually in the building for space heating and domestic hot water heating. AEA Review Comments and Recommendation The Cook Inlet Housing Authority proposes to install a ground source heat pump system in the Seldovia House housing complex in order to reduce the building’s heating oil consumption. Despite some unknowns regarding ground source heat pump performance on the Kenai Peninsula, the economics of the proposed installation appear to hold up to a range of conservative assumptions. The project could provide useful GSHP performance data for the Kenai Peninsula in addition to demonstrating the effectiveness of a hybrid heat pump/fuel oil system. The high cost of fuel oil in Seldovia makes the potential savings of a ground source heat pump attractive despite higher local electricity costs. Full funding recommended.

The project will reduce the cost of heat by offseting 11,400 gallons of fuel oil with 99 cords of firewood per year. The biomass heat system will be located in a stand-alone building (new construction) located adjacent to the project buildings. The project site and all project buildings are controlled by the Village of Minto. The wood fuel will be sourced from nearby forests owned by Seth-De-Ya-Ah Corporation, which has provided a letter of commitment for the project. Fuel harvests will be completed by Minto’s trained wildfire crew, and the crew boss has provided a letter of support for the project. A harvest plan will be completed by Tanana Chiefs Conference, and is included as part of the project budget. The project emerges from significant community energy planning efforts and project prioritization, including the US DOE Strategic Technical Assistance Response Team (START) program and wood energy assessment supported by the Alaska Wood Energy Development Task Group. AEA Review Comments and Recommendation Village of Minto proposes final design and construction of a biomass boiler system that is low emission, high efficiency, and 3rd party tested to supply heat to the Minto Multi-Purpose Building/Lodge and the Health Clinic. The system would consume approximately 99 cords per year and displace 11,400 gallons of fuel oil per year. Reconnaissance assessment through the Alaska Wood Energy Development Task Group indicates a viable project. Village of Minto is supplying a building to house the boiler (s) as a match. AEA is concerned by the lack of a harvest /operations plan for the project, but it is a deliverable. However, we recognize the existing fuel wood market in the interior Region. AEA will work with the grantee to ensure that building energy efficiency is addressed in conjunction with this project. Recommend full funding for final design, permitting, and construction with requirement that Minto provide a harvest plan; business/operations plan; biomass storage; final design that must be reviewed and approved by AEA before construction funds are disbursed.

DNR/DGGS Feasibility Comments DNR/DOF Feasibility Comments This project submitted by the Minto Village Council seeks final design and construction funding to install a hydronic wood boiler serving the multi-purpose building and the health clinic. The actual boiler type will be determined in consultation with the Council and AEA. The proposal states that the wood will be sourced from local forests owned by the village corporation, Seth-do-ya-ah. A forest inventory conducted by the Tanana Chiefs Conference Forestry Program concludes that a project using about 100 cords per year could easily source all its fuel within one mile of the Elliot Highway. Wood species would primarily be fire killed spruce with some green timber as well. TCC will also assist the village in developing a harvest and operations plan to ensure sustainability of the project. It is expected that 11,400 gallons of fuel oil will be offset by the use of wood. Oil prices average about $5 per gallon and the delivered wood price is estimated at $200 per cord however this amount seems low for Interior Alaska and may be closer to $250 per cord. An important aspect of the project is a statement from the executive director of the village corporation supporting the project and committing to resource supply. The letter states that the corporation supports harvest in the burn area that is located approximately 40 miles north of the village.

The Science Center has already conducted significant feasibility and reconnaissance work on this project. With the help of the Rasmuson Foundation and Foraker Group, they have conducted an energy audit, a heat pump evaluation, and a master plan for the facility. A significant amount of funds have been raised to improve the energy efficiency of the structure through renovations of roof, windows and exterior. These renovations will compliment the project proposed here. Raw sea water flow of up to 85 gallons per minute will serve as the heat source. The sea water is drawn from a depth of 65 ft via an existing 8” intake line and shoreside pump station. A buried manifold pipe delivers sea water in to the basement of the building where the heat pump system will be located. The sea water will transfer heat thru a titanium plate heat exchanger to a glycol loop that in turn will serve as the source side of the new heat pumps. Three 84,000 BTU/hour high efficiency water to water heat pumps will be installed in the existing mechanical room. The existing heating oil boiler and electric boiler will be replaced by the three new heat pumps. On the load (hot) side of the heat pumps, two buffer tanks will be heated from 115F to 145F, these will in turn supply hydronic heat to new low temperature baseboards also included in the project. A heat pump controller will modulate the temperature of the hydronic heat based on outdoor air temperature. This project will be the first sea water source heat pump system in Sitka, and the first water source heat pump system in Sitka to displace 100% of its existing annual heating oil and electric resistance heat. The proposed heat pump system is anticipated to perform with a seasonal COP of 3 or greater, due in great part to the reliably warm sea water from Sitka Sound. Project Location: 834 Lincoln Street, Sitka AK 99835 AEA Review Comments and Recommendation The City and Borough of Sitka proposes to install a sea water source heat pump system at the Sitka Sound Science Center. Because the Science Center is already equipped with a sea water intake to supply its aquarium and hatchery, the proposed project represents a lower cost opportunity to install a sea water source heat pump system relative to other buildings. According to AEA’s review, given the anticipated capital costs of the proposed system, the size of the building and existing heat loads would not result in the displacement of a sufficient quantity of diesel for system payback. However, the possibility of expansion of the system to provide heat to additional nearby buildings could make the project more economically compelling. AEA recommends funding for the design portion of the project with the requirement that incorporation of additional loads be considered in order to improve overall project economics. Partial funding recommended.

The woody biomass fired boilers will replace outdated heating oil boilers, which are costly to maintain and run on heating oil number 2, which is more expensive than locally sourced woody biomass. These systems will, in turn help to stabilize and secure the forest products industry of Southeast Alaska through the sourcing of locally- produced wood pellets. AEA Review Comments and Recommendation The Ketchikan Gateway Borough requests funding for construction to build two biomass heating system for the Ketchikan Airport and Ketchikan High School. The project is estimated to displace 111,033 gallons of fuel/year and has the potential to save the Ketchikan Gateway Borough fuel costs in excess of $ 8.0 million over 20 years. Due to the differing economics of the two proposed projects, AEA recommends partial funding for the Ketchikan Airport pellet system installation only. Before any funding is released to the grantee, AEA must review and accept the final design for the pellet system, the business/operations plan, and a biomass fuel supply plan. The system must meet AEA’s biomass program requirements of low emissions, high efficiency, third party tested, and UL listed (the product meets public safety requirements as designated by the Underwriters Laboratories). Ketchikan Gateway Borough should reevaluate the potential for a biomass system at the high school after the final design has been completed.

The boilers would be designed to use standard grade pellets which allow for higher ash content. The total combined demand is approximately 1,230 tons per year at an average price of $275 per ton. Discussions for a long term pellet supply contract have been made with Tongass Forest Enterprises that is offering contracts up to 5 years in length for volumes exceeding 500 tons per year. A silo would house the bulk delivery of pellets in Ketchikan. This successful fuel delivery model is similar to what is employed in Juneau to provide pellets to the Sealaska corporate building.

AEA Review Comments and Recommendation The Alaska Native Tribal Health Consortium and the City of Brevig Mission are proposing to design and construct a recovered heat system from the existing power plant to the Water Treatment Plant and the Washeteria/City Office. The Heat Recovery System will require the installation of a marine manifold on one of the existing generators. The Preliminary Heat Recovery Assessment was completed in September of 2013 and showed sufficient excess heat to support this project. The intertie to Teller was damaged and AVEC is working with FEMA on repairs. Significant more recoverable heat will be available when the intertie is repaired, and the heat recovery system should be designed to handle this heat load. The uninsulated AVEC power plant modules should be insulated to maximize available heat. Recommend full funding.

The projected amount of biomass needed per year is 2,500 tons with a delivery cost of $200 per ton. An updated forest inventory completed by Tanana Chiefs Conference in 2012 reported biomass dried tons within various radii of Galena. A sustainable annual harvest level of over 3,600 tons is available within a 4 mile radius indicating ample resource availability for the project. The village corporation has signed a letter of support and is willing to enter into a contract for the sale of timber which will support procurement of the biomass. This commitment combined with nearby state lands that would also be available as a raw wood supply should provide a means for a sustainable timber harvest operation in this area of Alaska.

The first building is the multipurpose building which houses an ice hockey rink and shooting range. The intent is to use the biomass plant to heat the shooting range and toilet group portion of the multipurpose building, approximately 10,000 square feet. The second building is the Zamboni garage which would approximately 1 ,400 square feet. The heating loop will connect to the Tok School Biomass Plant that was completed in the fall of 2010. (The Tok School Biomass Plant was developed using AEA Round I Grant Funding. The project consisted of a Biomass heating facility that contained an automated biomass heating system that now provides heat to the existing K-12 School.) Since the completion of the Tok School Biomass Plant a steam turbine and electrical generation system have been added to create a combined heat and power (CHP) system. The original biomass boiler was sized to allow for the CHP expansion and the additional load of the multipurpose building and Zamboni garage. The CHP project was completed the fall of 2012. When the CHP system is in operation it generates a substantial amount of heat as a byproduct. The heat created currently surpasses the required heat demand of the existing K-12 School. The intent is to recover the surplus heat and supply it to meet the heating demand of the additional buildings mentioned above. The cost for maintenance and operation as well as for biomass fuel will be negated for this project due to the current operation of the CHP system. Project Location: 249 Jon Summar Road AEA Review Comments and Recommendation Alaska Gateway School District proposes adding on a heat loop off the newly-completed wood-fired heating system at the Tok School to provide heat to two school buildings – the multipurpose building housing the ice rink and shooting range and the Zamboni building . The project team would complete a final design phase and construction documents prior to construction. This application is similar to the Round 6 submittal #926 that was recommended for funding, but below the $25MM allotment. This Round 7 application significantly decreases the number of buildings and the size of the proposed in the heat loop.

Existing antiquated hydronic heating systems in each building will be replaced and upgraded to improve efficiency an estimated 25%. Concurrent to this project, VEEP projects (Yakutat is a 2013 VEEP recipient) will be conducted to increase envelope efficiency per AEA statewide goal of 15%. AEA-required performance metering is addressed through ACEP subcontract. With significant local match and good project partners, we are seeking the funding for Phases III and IV: final design, purchase and installation of 2 Garn WHS2000 boilers, pipe installation and associated link up plumbing to all three buildings in the district heating loop. The project also includes construction of a separate boiler building and a cordwood storage/drying building. Per standard practice, existing oil furnaces will remain as supplemental and emergency back-up heat systems. The City and Borough of Yakutat, along with Yak-tat-Kwaan, want to ensure that we install the most effective technologically and economically appropriate equipment for our biomass district heating loop. We are pleased to have the interest of Garn Boiler Company in participating in this application based on the estimate for the equipment they suggested as most appropriate for the buildings involved. Garn has a proven track record of installing and operating their equipment in several locations in Alaska, including at least two that we know of in the coastal SE Alaska environment. It is our plan to also closely monitor developments in the biomass energy world, and we recognize that this technology sector is evolving. During the 9th month period of AEA review, legislative approval and appropriation, CBY and Yak-tat-Kwaan will continue to monitor technological development. One of our goals for the project is to link Yak-tat Kwaan’s forest management program and the biomass products produced with the installed boiler technology and have the best opportunity for expansion and integration of future biomass projects. CBY is prepared to operate and maintain this project, and has demonstrated ability to operate energy infrastructure through the electric utility, Yakutat Power. Project Locations in Yakutat, AK: City Hall Building: 309 Max Italio Drive, Court House Building: 120 Max Italio Drive,, Yakutat Community Center: 100 Ridge Road. AEA Review Comments and Recommendation The City and Borough of Yakutat is proposing final design and installation of low emissions; high efficiency; 3rd party tested cordwood boiler systems to heat three City/Borough-owned buildings: City Hall Building; Court House Building; Yakutat Community Center . This project is estimated to displace a total of 7,238 gallons per year of fuel oil, using 38 cords of wood per year. The project has completed a feasibility study. This project is an example of good collaboration efforts among community organizations in an effort to provide low cost heating to the entire community of Yakutat. Also the local community appears to be supportive of a district biomass heating project. AEA will work with the grantee to ensure that building energy efficiency is addressed in conjunction with this project. AEA recommends partial funding of design and permitting to allow the City and Borough of Yakutat to make an informed decision about pursing biomass as a heating option. Recommend partial funding with the requirements that AEA must review and accept the final engineering design; biomass storage; business/operational plan; harvest plan; inventory plan, $103,000.

DNR/DGGS Feasibility Comments DNR/DOF Feasibility Comments This project submitted by the City and Borough of Yakutat requests design and construction funds for two Garn 2000 boilers. The boilers will displace about 7,000 gallons of diesel and consume 38 cords of wood. Forest Service and village corporation lands are nearby with an extensive road network built from previous harvest operations. From recent inventory analysis as stated in the proposal, a sustainable annual supply of 800 cords is available. Stands are generally second growth on previous cut over lands. Many of the forest stands are in need of pre-commercial thinning. The Village Corporation and Forest Service have committed to making the timber available. The current rate of fuelwood in Yakutat is $200 per cord. It is not clear in the proposal of who would provide this material or what firewood vendors are currently doing business in the area.

In conjunction with SMMS, the City proposes installation of an innovative heat recovery system that captures waste heat from exhaust fans EF-4 & EF-5, minus 80 tissue freezers, IT .server room, electrical and mechanical room, fan coils and animal and necropsy refrigeration. Heat recovered will be directed to the front end of the seawater heat pump system and this will increase the coefficient of performance (COP) of this system. AEA Review Comments and Recommendation The City of Seward proposes to install a run around heat recovery loop in the Alaska SeaLife Center to recover wasted heat from exhaust fans, appliances, and overheated rooms and deliver it into the building’s sea water source heat pump system, resulting in improved heat pump performance. The calculated benefit derived from improved heat pump performance expected with the addition of the recovered heat into the system appears to be marginal, even assuming a dramatically increased heat pump output than is currently used. However, the additional benefit of avoiding the costs of a dedicated split cooling system for the overheated rooms is substantial. Even using more conservative assumptions regarding performance increase, the project appears to be economic. Full funding recommended.

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 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.

ETS units are used to capture and store surplus wind energy and use it to displace home heating fuel. The increase in the number of residential ETS units is needed to absorb wind generated energy during modest to high wind periods, which occur in throughout the fall and winter, when heating requirements are the greatest. The addition of 20 ETS units increases the productivity and efficiency of the existing wind system. AEA Review Comments and Recommendation Tuntutuliak received REF Round 2 and direct legislative appropriation funding to install five Windmatic 17S 95-kilowatt wind turbines, completing that project in 2012. This proposal would make use of excess electricity by diverting surplus kilowatts to residential heat loads. Unlike the other two project proposed for Kongiganak and Kwigillingok, the economics of this project suffer from the lower residual energy available having already installed 30 stoves instead of just 20 stoves in Kong and Kwig, plus Tuntutuliak's ~10% lower wind regime, plus their lower cost of diesel fuel.

Currently, each school’s hot water heater is part of the heating plant, which is separate from each building. For example, the Kotzebue school’s hot water is heated indirectly with hot glycol from a boiler module, which also provides space heating. The boiler water heats the school’s two huge plate and frame heat exchangers where the schools glycol/water-heating medium is heated. Hot glycol is then circulated through a plate type heat exchanger (for 115 degree water) and an Amtrol hot water maker for 140-degree hot water. During the warmest months of the school year, the school must run a boiler to make hot water. One boiler contains 385 gallons of water, the piping that connects it with the plate and frame heat exchangers contain approximately 200 gallons. Thus there are times when the school does not need space heating, but does have need for hot water; just as all the other school’s do. AEA Review Comments and Recommendation The Northwest Arctic Borough School District (NWABSD) applied for a grant to fund the construction of solar thermal water heating systems at eleven schools. Grant funds of $456,252 were requested with a match of $11,000 for a total project cost of $467,252. The project is intended to allow the boilers at the eleven schools to be turned off during summer months. It would also offset water heating fuel use during other periods of the year. AEA does not recommend this project for funding. The applicant made an error in reading solar panel output on p.39 of the application. 3.1 kWh/m^2/day is the solar insolation on the panel. The panel thermal output is 3.2 kWh/panel/day. A confusion between the energy output expressed in units of ‘per panel’ and the insolation expressed in terms of energy per square meter resulted in an over-estimation of energy that would be generated. Also, the application did not include enough detail regarding school occupancy during school days, summer months and on weekends, and associated water heating requirements, to calculate the related fuel use and potential savings. AEA recommends that NWABSD investigate advanced controls, alternative sources of water heating, and energy efficiency measures to reduce water heating fuel use at these facilities. AEA encourages NWABSD to work directly with AEA staff to address the community energy needs. Please contact AEA’s energy planning staff for direct assistance. This project is not recommended for funding.

The project will also be used as a demonstration projectfor the community to learn about solar thermal and wood pellet boiler systems and to encourage the use of renewable resources for heating. Project location: 21117 Myers Avenue Sutton, Alaska 99674 AEA Review Comments and Recommendation The Chickaloon Native Village proposes construction of a pellet and solar heating system to supply heat for both a 3,200 sq. ft. shop/office and a 1,160 sq. ft. administrative building. Included in the project is construction of a building addition to house the boiler system, purchase and installation of solar thermal panels and pellet boiler, and focused monitoring and evaluation. AEA recommends partial funding for Chickaloon Native Village pellet system installation only because the thermal only capital cost is less than the solar/thermal capital cost; the benefits and savings are the same when comparing solar/thermal and thermal technology. Before any funding is released to the grantee, AEA must review and accept the final design for the pellet system, the business/operations plan, and a biomass fuel supply plan. The system must meet AEA’s biomass program requirements of low emissions, high efficiency, third party tested, and UL listed. AEA recommends partial funding of $97,000.

Projects may be required to perform a geohazards site survey as a condition of receiving construction permits, depending on location of proposed site. DNR/DGGS Feasibility Comments DNR/DOF Feasibility Comments This project is a resubmittal of a Round 5 proposal for construction of a combined wood pellet boiler and solar thermal system that would provide heat for both a 3,200 square foot shop/office building and a 1,160 square foot administration building. This is a similar system that is installed in the Ionia community located in Kasilof. It is expected that this combined system will displace 1,818 gallons of diesel fuel per year and 1,022 gallons of propane for a combined savings of $11,560. Wood pellets would come from either in-state suppliers such as Superior Pellets in North Pole or from Gulkana Village’s small pellet plant. Pellets may also be purchased from local building supply stores. Given the relatively small annual pellet requirement, sourcing a reliable supply should not present a problem. The project proposal lists a purchase price of pellets at approximately $250.00/ton and a 15 ton requirement which totals $3,750 per year in pellet costs.

The estimated fuel oil savings to the community water plant and washeteria is projected to be 6,600 gallons of heating oil per year. For more detailed information, see the attached updated Tuntutuliak, Alaska 2013 Heat Recovery Feasibility Study. AEA Review Comments and Recommendation The Alaska Native Tribal Health Consortium and the Native Village of Tuntutliak are proposing to design and construct a recovered heat system from the existing power plant planned to the Water Treatment Plant and Washeteria. The Preliminary Heat Recovery Assessment was completed in September of 2013 and showed sufficient excess heat to support this project. The utility has funding for an electric heater for excess wind. The design should take into account the integration of wind-to-heat. Recommend full funding.

It is designed to achieve the economies of scale, customer convenience and price stability of traditional district energy systems, while allowing the adaptability and flexibility needed to serve a community with a spatially extensive development pattern, typical of Southeast Alaska. AEA Review Comments and Recommendation The Organized Village of Kake is proposing final design and permitting for a low emission, high efficiency, and 3rd party tested district wood-fired heating loop for a tribal government office building, Kake City School District, Tlingit and Haida Senior Center, the City of Kake’s Bingo Hall, and a lodge owned by the Organized Village of Kake (OVK), a federally recognized tribe. This project is estimated to displace approximately 35,000 gallons per year of fuel oil. The application includes substantial support from the community and endorsement from the Kake Community Energy Committee. AEA recommends partial funding of design and permitting to allow the Organized Village of Kake to make an informed decision about pursing biomass as a heating option. AEA recommends partial funding for the final design and permitting includes business/operations plan; biomass storage; biomass resource inventory assessment; harvest plan, $175,000.
