The Nenana Student Living Center (NSLC) is a 27,000 sq ft student dormitory in Alaska’s Interior village of Nenana that houses and feeds 88 students and 10 staff members during the school year. The building is owned by the city of Nenana but operating costs are paid by the Nenana School District. This building has in-floor radiant heating across approx 20,000 sq ft. Due to the architecture of the building (1-story, view from above looks like a U) there is more than 11,000 square ft of exterior wall. Over a typical year the building burns 27,000-30,000 gallons of heating fuel, consuming 150-200 gallons each day during the coldest parts of the interior Alaskan winter. Operating costs are passed directly onto the already burdened school district. Integrating a large solar hot water array with heliodyne flat-plate solar collectors, a large solar hot water storage tank, dual coil DHW tank, forced air heating preheat loops and already planned insulation upgrades we can offset up to 30% of the building’s heating costs. With heating fuel at $3.50 gal coming into this winter that will save $30,000 in the first year alone. Renewable Energy Fund Grant Application Round 5 AEA12-001 Grant Application Page 4 of 40 7/1//2011 2.5 PROJECT BENEFIT Briefly discuss the financial and public benefits that will result from this project, (such as reduced fuel costs, lower energy costs, etc.)   The average cost of fuel during the 2009/2010 heating months was $2.57/gal in the interior. Two years later, prices are poised to hit $3.50/gal a 36% increase. Though the impact on individual residents has been well publicized, less attention is being paid to small school districts that often have to heat the largest energy consumer in a rural community – the school. High utility costs mean that school systems have less funding available for much needed upgrades, teachers, support staff and vocational programs. This means that the communities and youth attending rural schools suffer. At the current cost per gallon and their rate of fuel use, the Nenana school district is projected to burn through $100,000 of heating oil at their Student Living center over the next year. By implementing this solar space-heating project we will save the Nenana School District up to 30% or $30,000/yr. As fuel prices go up, these savings will increase. That money can be put toward other efficiency upgrades and much needs scholastic programs. Solar hot water is a sustainable, renewable solution to assist with the heating needs of rural communities. When implemented correctly, buildings in an area of high solar radiation – like Alaska’s interior – can easily offset a large portion of their space heating and DHW needs. By installing, studying and monitoring this project and producing a list of useful best practices, we have the opportunity to save the Nenana School District a significant amount of money, create a project that can be duplicated in other areas of Alaska and save state and taxpayer dollars. Once the system is installed, maintenance is minimal and the system can be monitored and maintained similar to an existing boiler. Just as the Tok-school biomass project is being touted as a model for energy generation throughout the state, the Nenana Solar Student Living Center can be touted as a simpler, less labor-intensive solution to high-energy costs. Because of its close proximity to Fairbanks and high visibility we anticipate a lot of publicity from this project. 2.6 PROJECT BUDGET OVERVIEW Briefly discuss the amount of funds needed, the anticipated sources of funds, and the nature and source of other contributions to the project. The total estimated project costs requested from the Alaska Energy Authority are $300,000. That includes design and construction costs, modifications to the existing mechanical room to make way for the storage tank and piping, heat exchangers, modifications to the existing DHW system to integrate the solar hot water, 1.5 years of project oversight/data monitoring and labor to install and maintain the system. The planning of this system involves the use of existing information being brought together to design a successful project. Much of the engineering work and labor to setup the system can be done in-kind by product suppliers and engineers. The value of this in-kind work is expected to be at least $25,000 Renewable Energy Fund Grant Application Round 5 AEA12-001 Grant Application Page 5 of 40 7/1//2011 A portion of the labor costs will come in the form of donated labor from the school district’s facility engineers who operate and maintain the existing equipment. They will be absorbing the cost of preparing the utility room to hold the new solar hot water storage. This cost alone is expected to run $15,000. A large air vent leading into the utility room needs to be sealed and relocated to make way for the solar hot water storage and multiple piece of equipment need to be relocated. The city of Nenana has dedicated additional support which is hard to quantify but has essentially told us that any of its resources are at the disposal of the project. Heavy equipment, scaffolding, ladders, excess material such as unistrut. It will be easier to quantify this in-kind donation as the project progresses 2.7 COST AND BENEFIT SUMARY Include a summary of grant request and your project’s total costs and benefits below.

Solar hot water is a documented resource that has been used commercially for more than 30 years in the lower 48. Here in Alaska solar hot water is still struggling to gain public acceptance though its usefulness has been shown in a variety of smaller studies, mainly for DHW, the ability of a large solar thermal array to offset space heating and DHW has yet to be documented. The main contractor proposed for this project is ABS Alaska, the same company that designed and installed the Denali Park Solar Thermal project. Their reputation surrounding solar, wind and solar thermal installations is extremely positive throughout the state and they’re one of the few contractors in Alaska that have experience on a solar thermal project of this size. The company owner Jim Norman is involved with the state-wide Renewable Energy Alaska Project (REAP) and ABS was a key partner and supplier for the YRITWC’s hydrokinetic turbine installation in Ruby Alaska. We have a solid relationship with ABS through the lead-acid battery recycling program which the watershed council runs in villages throughout the interior. Renewable Energy Fund Grant Application Round 5 AEA12-001 Grant Application Page 8 of 40 7/1//2011 After research into a number of the different products in use throughout Alaska Heliodyne Inc manufacturer of flat-plate solar collectors has been selected as the likely project partner. The Heliodyne systems have stood up to the rigorous testing in rural Alaska and have a low failure rate for their components. They use top of the line Grundfos pumps for their system and the YRITWC has worked with their equipment on previous solar hot water projects. They have volunteered to assist us with a dashboard monitoring system, which allows for easier understanding of the energy produced by the solar thermal array. They’re also donating a significant amount of time to assist us with the design of the solar thermal system on the NSLC. 3.5 Project Communications Discuss how you plan to monitor the project and keep the Authority informed of the status. Communication and information are two of the biggest impediments to renewable energy in Alaska. Due to the harsh arctic climate and sub-zero temperatures projects that have been well documented in the lower 48 run into issues here in Alaska. The few companies who are installing Renewable Energy systems often lack the resources to complete proper data collection and reporting that would prove the system’s efficiency and create usable examples for other entities to follow. That is one area the Watershed Council thrives in. Our role is to provide honest analysis and recommendations to all entities both inside the watershed and throughout the state. A big component of providing clear results involves collecting detailed, accurate information on system energy production while the system is operating. Heliodyne Flat plate collectors have an excellent operating reputation both in the lower 48 and here in Alaska. Their existing monitoring system allows the controller to optimize operation and monitor BTU savings based on current real-time weather data. The interface provided under normal Heliodyne operation is enough to satisfy the experienced solar installer but for the lay- person a simpler break-down of fuel savings and system efficiency is required. The YRITWC and ABS Alaskan already have well-established relationships with Heliodyne. Working together with this supplier we will provide a detailed look at the efficiency of the system and a simpler method of understanding the realized fuel savings, project costs and required maintenance to keep the system operating. The project manager will coordinate each stage of the project in conjunction with a designer from ABS Alaska, the facility engineers in Nenana and Engineers from Heliodyne, the collector manufacturer. Quarterly reports will be submitted to AEA detailing project successes and stumbling blocks -more frequent reports may be requested. Project finances will be coordinated through the YRITWC and funding draw downs will be submitted on a quarterly basis throughout most of the project. 3.6 Project Risk Discuss potential problems and how you would address them. Potential problems: 1. Too much heat being produced during the summer and insufficient use of the heat resulting in stresses on the system. There are many ways to deal with this. One option is to install cooling fins on the roof. Renewable Energy Fund Grant Application Round 5 AEA12-001 Grant Application Page 9 of 40 7/1//2011 Because Alaska rarely has long stretches of high temperature and Nenana is in a wind zone we don’t expect this to be an issue. We’ll also be heating DHW during the summer when up to 10 residents live in the building. Another option, should we produce excessive amounts of heat is to hook in ThermoElectric batteries - a method of electrical production using 2 dissimilar metal to produce electricity (similar to a sterling engine but with no moving parts). This can be done very effectively using a small cooling loop running through the ground in the court-yard to provide the cooling energy and produce electricity 2. The solar hot water controls fail to interact efficiently with the existing boiler controls. Siemens controls makes a number of additional controls for their heating system, many of which integrate well with solar hot water. I’ve spoken with Siemens and have been assured that if any problems arise with the existing system it will be an easy modification to their existing controls or at worst a cheap (under $500) upgrade. 3. Inability to effectively measure the gallons of heating oil replaced and relate the sun’s irradiance to replaced BTUs The YRITWC has experience using the Heliodyne monitoring system and is well aware of the benefits and deficiencies of the monitoring system. We plan on installing additional flow meter and temperature sensors to different parts of the system to double and potentially triple check the readings being recorded by Heliodyne Thermistors. We also plan to utilize a small panel that will measure the sun’s irradiance and correlate the data from the irradiance sensor with the solar collector’s BTU production. 4. There is not enough room for a large solar storage tank inside the existing mechanical room The mechanical room is nearby an existing open courtyard, if the analysis shows that the solar production needs a thermal battery storage it will be possible to use a larger tank located outside the building, the tank can be well insulated and buried. Renewable Energy Fund Grant Application Round 5 AEA12-001 Grant Application Page 10 of 40 7/1//2011 SECTION 4 – PROJECT DESCRIPTION AND TASKS • Tell us what the project is and how you will meet the requirements outlined in Section 2 of the RFA. • The level of information will vary according to phase(s) of the project you propose to undertake with grant funds. • If you are applying for grant funding for more than one phase of a project provide a plan and grant budget form for completion of each phase. • 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. Documented Energy studies from the Cold Climate Housing Research Center in Fairbanks, AK have confirmed predicted values from the f-chart solar thermal production calculator. This information shows that there are 390,000 BTUs of heat available per sq foot of heliodyne flat plate solar collector at a 90 degree tilt angle. The only limit to harnessing this heat is space and cost. The heat energy is available and can be successfully harnessed from the sun. Pros and con’s Pro’s: 1. Low maintenance/organization cost. The energy source is reliable and once the system is setup it can be less maintenance than a normal oil-fired boiler. (Our system on the rec center in Nenana has been in operation for 1 yr and has only required 1 small change in the location of a thermistor -aprox 30 minutes- meanwhile the heating company has been in at least 2-3 times in that same time span to fix/clean the boiler) 2. NO staff/supply chain to manage NO fuel drops to worry about, NO wood to cut/stack/dry 3. This is a renewable resource that if developed and further studied can be utilized in a number of communities throughout the state 4. This system will lower the school district’s exposure to fluctuating world oil prices 5. Renewable Energy is difficult to produce in interior Alaska during the winter, most of the interior is a class 1 wind resource (poor), rivers/streams are frozen BUT on a clear day the interior has superb solar resources during the shoulder heating season Late Feb-Early May, late Sept-Nov. With a large enough array and heat storage some of the heat produced during the day can be stored and later released. During the summer plenty of heat will be produced to offset DHW needs. Con’s: 1. During the time of year when heat is needed most, there is the lowest resource (Dec-Jan) 2. Just like any water plumbing system, because there are mechanical pumps and flowing glycol throughout the system parts can wear out and need to be replaced – similar to a wind turbine or oil -fired heating system, It’s not quite as maintenance free as a solar PV 3. During the time of year when heat is needed least it is produced in excess. BUT- there are Renewable Energy Fund Grant Application Round 5 AEA12-001 Grant Application Page 11 of 40 7/1//2011 always methods of harnessing excess energy (ie thermal electric generators) Discussion: Throughout rural villages in half of Alaska the new hot ticket word is “biomass.” On paper biomass may be our most sustainable resource. Not only is it renewable but it provides economic development for community members. Money can be kept in the community and used to put people to work not sent out to the barge and oil companies The problem is the supply chain management for biomass is a complicated thing for some communities to implement. It’s going to involve breaking the norm of calling up the fuel company for a delivery, you need somebody in the community to manage the system, to plan ahead and keep records of use so that wood can be stockpiled and dried a year in advance. The reality I see in my communities is that some places are not a good fit for certain technologies and there is NO blanket solution that will work everywhere. Some of our communities have trouble filing their PCE reports every year, it’s going to be very difficult for them to manage a supply chain for biomass to heat a major building that they don’t own or live in. In one of the communities I work with the tribal IGAP worker has changed 5 times in 2 years – that’s a difficult turnover rate to overcome. Solar thermal will continue to operate regardless of turnover rate in a community, it can be monitored remotely and companies like ABS will continue to be around to service it as needed. The 4 biggest potential energy sources for rural AK are oil, wind, solar and biomass. Oil is prohibitively expensive, wind is simply unavailable in most parts of the interior, biomass can involve a level of complication that some communities cannot handle. Solar hot water is as simple or simpler compared to oil fired heating systems, there is an abundance of it throughout Alaska’s interior and once installed there’s very little maintenance. 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 about the number, size, age, efficiency, and type of generation. The energy system for the Nenena Student Living Center is a single 10yr old Burnham PF-507-S model 1,372,000 BTU furnace with an efficiency of ~80% that heats the 27,000 sq ft building with aprox 7,000 sq ft of forced air and 20,000 sq ft of radiant floor. The boiler is set to heat glycol up to ~180F for the forced air units and radiant floor. There is a forced air intake preheat that we also plan to hook into the solar hot water system. The radiant heat is tempered down to 90F when it leaves the mechanical room. This is an ideal temperature to extract energy from solar hot water. Also included is an 80-gallon, direct fired DHW tank for DHW throughout the building. This burns oil even throughout the summer to provide hot water to the building’s 10 year-round residents and summer camps. With a DHW tank upgrade and solar thermal we expect oil consumption during the summer to be 80-90% replaced by solar. Heating bills from 2009-2011 indicate that the building burns between 27k – 29k gallons of heating fuel/yr for DHW and space heating. At 3.50/gal that is nearly $100,000/yr. We estimate this system can offset 30% of that load or $30,000 annually. (Heating Bills see Appendix C) Renewable Energy Fund Grant Application Round 5 AEA12-001 Grant Application Page 12 of 40 7/1//2011 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. Electricity consumed by the Student Living Center comes from the local utility GVEA and costs $.15/kWh. Heating fuel is trucked in from Fairbanks by Alaska Aero Fuels who charges the cost/gal for heating oil plus a surcharge for the 114 mi r/t delivery fee. Looking at the heating bills from the last 2 years there are many weeks during the winter when a fuel truck drives down from Fairbanks once/wk to refuel the student living center. Because of the large quantity of fuel the building requires the contract for delivery was shifted from Nenana Heating Company – a local business – to Alaska Aero Fuels 2 years ago. This is because the company can deliver larger quantities of heating fuel at cheaper costs. This change shifted more money out of the small community. If we can offset heating fuel to the point where Nenana Heating Company is once again competitive there’s a chance to use less fuel and keep more of the money spend on that fuel in the community. After the completion of the YRITWC energy upgrade to the nenana rec center in 2010, we presented our results to the community at local community meetings and had everyone in town talking about the technology and the money we were saving Nenana. The mayor is interested in integrating solar hot water into the village’s municipal water supply and the school has requested funding to replace their older DHW tanks with dual-coil DWH tanks and solar hot water collectors. With a 2-collector solar thermal array and 20 panels of solar PV we’ve managed to shift the energy conversation in Nenana, AK to revolve around solar. If we can install a 30-40 collector solar hot water array and help heat one of the village’s largest buildings I think we can shift the conversation throughout half of the interior to focus more on renewable energy. (Project Spec sheet from Nenana, AK attached in Appendix D ) 4.2.3 Existing Energy Market Discuss existing energy use and its market. Discuss impacts your project may have on energy customers. The student living center was designed for appearance not efficiency so there is over 11,000 sq ft of exterior walls around the building and the heating load is tremendous. (Photo of NSLC attached in Appendix E) On top of that, the building is a dormitory for 88 high school students- not the most energy conscious age group. But these youth represent communities throughout rural Alaska and are the next generation of community leaders. They’ll take the knowledge of this project back with them to their communities and generate further interest in the technology. Nenana is an excellent test-bed for rural energy solutions because it’s a rural community but it’s in close proximity to Fairbanks. This allows the installers to test all of the challenges that will be faced in a rural community and deal with them at a fraction of the cost compared to a rural community – The YRITWC has learned this lesson the hard way through its Ruby Hydrokinetic project. The potential for heat generation and storage is huge in many areas of our state and as rising energy costs mount, we need to research alternatives to the millions of gallons of diesel burned Renewable Energy Fund Grant Application Round 5 AEA12-001 Grant Application Page 13 of 40 7/1//2011 annually for heat in rural AK. We plan to widely publicize the results of this project and make all of the information gained accessible. Our 2010 project in Nenana has already gotten the community and the major energy consumers in the community excited, this project will continue to bring more focus around renewable energy and energy efficiency. 4.3 Proposed System Include information necessary to describe the system you are intending to develop and address potential system design, land ownership, permits, and environmental issues. 4.3.1 System Design Provide the following information for the proposed renewable energy system: • A description of renewable energy technology specific to project location • Optimum installed capacity • Anticipated capacity factor • Anticipated annual generation • Anticipated barriers • Basic integration concept • Delivery methods Solar Thermal energy generation is 70-80% efficient at transferring the solar radiation from the sun into usable thermal energy used to BTUs. Compare that with conventional solar PV which is less than 20% efficient at transferring that radiation into kWhs of electricity. Solar Thermal systems are extremely good at producing large quantities of “low-grade” heat with temperatures less than 100F, they’re not as effective at producing large quantities of “high-grade” heat – temperatures above 150F which can be used for traditional space heating with baseboard. The hydronic heating system in the NSLC uses 90F glycol circulated through aprox 14,000 lineal feet of ½” radiant floor tubing. We intend to utilize the available BTUs from 40 solar hot water collectors to harness the abundant solar radiation in Alaska’s interior. Each collector is capable of producing up to 390,000 BTUs per sq ft over the course of the yr 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. Site ownership – The city of Nenana owns the building, the lot and surrounding land. They have requested that the watershed council assist them in applying for this project. 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 Applicable permits- There are no required aside from normal heating permits. The city mayor is a retired fire-fighter and knows the regulations in Nenana permitting is not expected to be an issue. Renewable Energy Fund Grant Application Round 5 AEA12-001 Grant Application Page 14 of 40 7/1//2011 Anticipated permitting timelines- see above ID and discuss potential barriers – since the project will take place within a building owned by a project partner there are no barriers anticipated. 4.3.4 Environmental Address whether the following environmental and land use issues apply, and if so how they will be addressed: • Threatened or Endangered species • Habitat issues • Wetlands and other protected areas • Archaeological and historical resources • Land development constraints • Telecommunications interference • Aviation considerations • Visual, aesthetics impacts • Identify and discuss other potential barriers All construction will occur on an existing building. No land development, or environmental impacts are anticipated. Visual impacts will not impair any views of the landscape because there are no homes within visual distance of the student living center. A potential barrier may be if the array is sized to large and a buried tank is required. But there are no sensitive wetlands in the area and any issues related to this will be addressed with the landowners – the city of Nenana, the entity applying for this grant. 4.4 Proposed New System Costs and Projected Revenues (Total Estimated Costs and Projected Revenues) The level of cost information provided will vary according to the phase of funding requested and any previous work the applicant may have done on the project. Applicants must reference the source of their cost data. For example: Applicants Records or Analysis, Industry Standards, Consultant or Manufacturer’s estimates. 4.4.1 Project Development Cost Provide detailed project cost information based on your current knowledge and understanding of the project. Cost information should include the following: • Total anticipated project cost, and cost for this phase • Requested grant funding • Applicant matching funds – loans, capital contributions, in-kind • Identification of other funding sources • Projected capital cost of proposed renewable energy system • Projected development cost of proposed renewable energy system Anticipated project costs are estimated at $340,000 of which $300,000 is being requested from the Alaska Energy Authority. Costs are based on MSRP supplied by the product manufacturer (heliodyne) which take into account shipping up to Alaska. Nearly all of the items provided in this grant application must be brought in from out of state. Project costs are also based on experience that the YRITWC has in project management specifically surrounding solar hot water. A small project used for space heating was designed and Renewable Energy Fund Grant Application Round 5 AEA12-001 Grant Application Page 15 of 40 7/1//2011 installed last year by the YRITWC with support from ABS Alaska. Though the scale of the proposed project is significantly larger the project that was completed in 2010 allowed us to gather rough numbers to be used for this application. Neither the applicant- the City of Nenana- nor the project partner – the Nenana School District – is in a financial position to contribute funds to this project. Both entities are seeking additional funds from other sources to weatherize the NSLC and make the impact of the solar hot water project even more effective. The capital cost of the renewable energy system –equipment and materials alone- is expected to be roughly $120,000. Other major expenses include shipping costs and labor for installation. The development costs are estimated to be upwards of $100,000 since a project of this scope has not been done in the interior of Alaska before. We anticipate that if this project is a success it will streamline the way for more efficient project in the future. 4.4.2 Project Operating and Maintenance Costs Include anticipated O&M costs for new facilities constructed and how these would be funded by the applicant. (Note: Operational costs are not eligible for grant funds however grantees are required to meet ongoing reporting requirements for the purpose of reporting impacts of projects on the communities they serve.) Project Operating and Maintenance Costs will be absorbed by the city/school facility managers, of these Chris Robinson and Rick Mackey are leads. Both have extensive plumbing, heating and electrical experience and will be involved with the installation of the system at all levels in order to fully understand the system. The city is anxious to learn more regarding the operation/maintenance of solar hot water systems because of their current plan to integrate a solar hot water system into their municipal water plant. Heliodyne offers a warranty on their solar collectors for 10 years and the electrical components for 3-5 years. Significant replacement costs are not anticipated to be an issue until well after the system has paid for itself. 4.4.3 Power Purchase/Sale The power purchase/sale information should include the following: • Identification of potential power buyer(s)/customer(s) • Potential power purchase/sales price - at a minimum indicate a price range • Proposed rate of return from grant-funded project There is no power purchase/sale for this heating project. In the unlikely event we are able to integrate thermoelectric generators into the design to produce electricity during the summer for sale back to GVEA – the local utility in Nenana- there is already a power purchase agreement published by GVEA - the GVEA SNAP program. 4.4.4 Project Cost Worksheet Complete the cost worksheet form which provides summary information that will be considered Renewable Energy Fund Grant Application Round 5 AEA12-001 Grant Application Page 16 of 40 7/1//2011 in evaluating the project. Download the form, complete it, and submit it as an attachment. Document any conditions or sources your numbers are based on here. (Attached in Appendix F) SECTION 5– PROJECT BENEFIT Explain the economic and public benefits of your project. Include direct cost savings, and how the people of Alaska will benefit from the project. The benefits information should include the following: • Potential annual fuel displacement (gal and $) 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 Benefits We estimate that this project will be able to offset up to 30% of the school’s heating requirements- which equates to roughly $30,000 at current energy prices. Assuming the equipment will be in place for at least 10 years – the warranty life of the solar collectors – that is an estimated savings of $300,000 The additional annual incentive provided by the project will be the employment and development of the AK renewable energy industry. Based on both contractual and direct labor and benefits spent on the project the value of that additional benefit- including distribution of information and consultation on renewable energy and energy efficiency work is estimated at $123,000. Because the school district is a non-profit it is not eligible for additional tax incentives or other renewable energy subsidies. However by taking a leadership role in their own energy situation, this project will make the NSLC a better candidate to apply for additional funding for energy efficiency and renewable energy programs through USDA, HUD and the state. Non-economic benefits to Alaskans include demonstrating to its young people that alternative energy generation is possible even in these far northern climates. Innovation related to energy is many times more effective when it’s presented to young people at an early age. The students living in the NSLC are leaders from across the state and being able to witness first hand the power of sustainably heating their own living space will have a huge effect on the youth who pass through the Nenana school district every year. Renewable Energy Fund Grant Application Round 5 AEA12-001 Grant Application Page 17 of 40 7/1//2011 SECTION 6– SUSTAINABILITY Discuss your plan for operating the completed project so that it will be sustainable. Include at a minimum: • Proposed business structure(s) and concepts that may be considered. • How you propose to finance the maintenance and operations for the life of the project • Identification of operational issues that could arise. • A description of operational costs including on-going support for any back-up or existing systems that may be require to continue operation • Commitment to reporting the savings and benefits The Nenana School district receives funding to keep their buildings in operation from the state of Alaska. Operational funding will continue and the building will be operated under normal guidelines. The school system is one of the most sustainable and organized entities in a rural community. In Nenana specifically, the facility maintenance engineer’s have a high level of experience with the heating and electrical systems in the building. Most components of the project can be replaced under warranty and any maintenance work can be performed either by ABS Alaskan or the facility maintenance engineers. Operational issues- stagnation due to high temperatures during the summer. There are pressure releases on the system designed to release pressure should the system ever reach stagnation. If these releases are ever damaged or destroyed they are simple to replace. Leaks/pump failure- these occur with any heating or water system. The staff at the NSLC will be able to repair these as they occur. Operational costs: Operational costs on a solar hot water system are designed to be minimal. The 2 panel solar collector that we installed in 2010 has required less than 1-hr of maintenance in the past year. If operational costs for solar collectors are estimated at roughly $.50 per sq ft of collector over the 10 yr life of the array than overall maintenance costs will be below $8,000 – much of that is in labor that can be supplied by the Nenana School District. The Yukon River Inter-Tribal Watershed Council’s Energy department is committed to providing sustainable, low cost energy solutions to the difficult energy situation in Alaskan villages. Without proper data reporting we have no purpose. It is a main-stay of our organization’s structure to maintain good standing with funding agencies and report on the results of our projects to our member villages, tribes and community organizations. We are fully committed to full and open reporting of energy savings, costs associated with the system and any issues that are encountered. SECTION 7 – READINESS & COMPLIANCE WITH OTHER GRANTS Discuss what you have done to prepare for this award and how quickly you intend to proceed with work once your grant is approved. Tell us what you may have already accomplished on the project to date and identify other grants that may have been previously awarded for this project and the degree you have been able to Renewable Energy Fund Grant Application Round 5 AEA12-001 Grant Application Page 18 of 40 7/1//2011 meet the requirements of previous grants. Experience: The YRITWC installed a 2-panel heliodyne collector on the Nenana rec center in 2010. David Messier the proposed project manager fitted pipes, sweated in fittings, T-d into the existing water supply line, completed all plumbing hookups and setup the monitoring equipment for the project. As a results this project has been designed with a thorough knowledge of the product and its production capacity in mind. Already completed: A site visit to the building was completed in early June of 2011 and meetings with the building maintenance staff ID’d viable sites for the solar storage tank and how the utility room could be reconfigured to make room for the tank. Building plans for the student center have been secured and indicate that the south facing metal standing seem roof is build on 2x10 trusses and has at least a 90lb/sq ft roof load capacity which will provide an ideal space to mount the array, even factoring in heavy snow loads. The building plans also show the length and diameter of radiant floor piping and give a full heating/mechanical schematic for the building. The plans also show the amount of insulation used, which will provide us with the necessary information for heating loss calculations when planning and designing the system. Time frame: Depending on the time frame of when the award will be granted all of the design work, equipment selection and monitoring details can be completed during the winter of 2011-2012. When grant funding is awarded the project will be ready to hit the ground running in the spring of 2012 after breakup. The summer is an ideal time to complete this project because of the weather but also because the school maintenance staff will have time to assist with the re-structuring of the mechanical room and installation of the system. If they’re involved from the beginning of the process – as they have been – than it will be a more sustainable system. The installation of the project can be completed entirely during the summer of 2012 and we will monitor the system’s performance throughout the 2012-2013 heating season to evaluate its efficiency. Past Grant successes: The YRITWC installed the first hydrokinetic turbine in the US in Ruby Alaska. The YRITWC installed and managed this project using funding from the Administration for Native Americans and the Alaska Energy Authority. When continuation of the project was deemed uneconomic, the YRITWC returned unspent grant funds to AEA promptly after completing a project closeout report. We have a very successful track record of completing required progress reports and financial draw downs with Alaska Energy Authority. We are completing a white paper detailing the difficulties with hydrokinetics and why we have decided to move away from the technology. In 2010 the YRITWC completed a solar/heating system upgrade to the Nenana Rec Center using a grant from the Administration for Native Americans to showcase renewable energy in a pilot project. We successfully completed the grant guidelines and were able to leverage other funding sources to go above and beyond the scope of our grant and implement 3 technologies – heating controls, solar hot water and solar electric production. Renewable Energy Fund Grant Application Round 5 AEA12-001 Grant Application Page 19 of 40 7/1//2011 We reported on this in 3 ways: -Heating information for the previous 3 years of the building’s use was logged and averaged to develop a baseline. Heating information after the building’s heating upgrades is being recorded and compared. Preliminary results show a saving of 1000 gallons of heating fuel annually. - Enphase microinverters were used as part of the solar array in Nenana. The monitoring we installed allows anyone, anywhere to view the current energy production in Nenana just by visiting the project site: http://enlighten.enphaseenergy.com/public/systems/BTcD7969   this allows funders, community members and anyone interested in our work to see real-time and historical data on our project. -Heliodyne’s monitoring system allows us to track how many BTU’s are being produced in Nenana by reporting 2 minute averages on heating data. This site is also accessible remotely for funding agencies and community members interested in data on the work we’ve done.   The financial officer at the YRITWC is a CPA candidate with 7 years of experience managing and reporting on federal, private and state grant funding. We have completed organization-wide audits according to GAAP and will attach a copy of our most recent audit along with this application. If you’d like further information on our successful projects/grant work please do not hesitate to contact me directly. SECTION 8– LOCAL SUPORT Discuss what local support or possible opposition there may be regarding your project. Include letters of support from the community that would benefit from this project. In 2010 the YRITWC completed a heating system upgrade, solar array and solar hot water collector system on the Nenana Rec Center. The project cost $25,000 to complete and is saving the tribe and city (who pay the utility bills) roughly $4,500/yr in heating and electricity bills. We’ve reported these results back to the community and have nearly the entire community of Nenana excited about Renewable Energy. We’ve received EXTREMELY positive feedback. At the most recent community dinner I presented our results at both the mayor and school principal stood up after me and expressed their appreciated and also mentioned that they were trying to get more projects installed throughout Nenana. Not a single person in the community has expressed dis-satisfaction with out work and each time I present at a community meeting people come up afterwards to discuss what they can do on their own home with solar to save money and energy Because of our tight time frame surrounding this application –the city only recently approached us regarding this project- we do not have a formal resolution from the city council authorizing us to move forward. We have included an MOU signed by the Mayor between the city of Nenana and the YRITWC and a formal resolution is expected to pass at the Sept 8 city meeting. A letter of support from the Nenana native council, Toghotthele Native corporation, Nenana school district and Tanana Chiefs Conference are included with this application Renewable Energy Fund Grant Application Round 5 AEA12-001 Grant Application Page 20 of 40 7/1//2011 SECTION 9 – GRANT BUDGET Tell us how much you want in grant funds Include any investments to date and funding sources, how much is being requested in grant funds, and additional investments you will make as an applicant. Include an estimate of budget costs by milestones using the form – GrantBudget5.doc Provide a narrative summary regarding funding sources and your financial commitment to the project. A significant amount of time has been spent educating the community of Nenana on energy efficiency and the monetary savings provided by renewable energy. The idea of completing a project on the Nenana Student Living Center has been a topic of conversation between the City of Nenana, the YRITWC and the Nenana school District for more than 4 months however the Renewable Energy Grant Fund was only recently identified as a potential method of funding the project. The YRITWC has a history of bringing together funding sources from state, federal, private and agency partners to complete projects successfully and with maximum community involvement. The requested grant funds from AEA are: $300,000 Additional Project funding in the form of in-kind support is estimated at $40,000 Grant Budget 5 in a separate document Renewable Energy Fund Grant Application Round 5 AEA12-001 Grant Application Page 21 of 40 7/1//2011 SECTION 10 – ADDITIONAL DOCUMENTATION AND CERTIFICATION SUBMIT THE FOLLOWING DOCUMENTS WITH YOUR APPLICATION: A.

Letters of Reference for David Pelunis-Messier August 25, 2011 Alaska Energy Authority 813 W. Northern Lights Blvd. Anchorage, AK 99503 RE: Renewable Energy Gant Fund Round V Alaska Energy Authority, This letter is to express support for David Pelunis-Messier’s project management skills in the installation of a solar hot water collection array at the Nenana Student Living Center in Nenana Alaska. I have had the pleasure to work with Mr. Pelunis-Messier for five years on numerous projects around the state, specifically the Yukon River basin. He has shown exceptional skill and discernment on how to effectively implement renewable energy projects in rural Alaska. His continual focus on finding and training community champions has lead to successfully implementing hydro-kinetic, wind, solar, and solar hot water projects in rural Alaska. The greatest skill that Dave brings to implementing an alternative energy project in rural Alaska is his understanding of how to bridge community dynamics, technical training, and effective outreach. Numerous studies exist showing the effectiveness of solar hot water collectors at northern latitudes, David’s technical understanding of implementation these systems and his keen insight into how to train community champions position this project to be a model for success over the long-term. Based on the merits of the implementation team this project has great potential to enhance the sustainability of rural communities by helping lower the cost of living in rural Alaska.

The project consisted of 3 main components: Zone valves and programmable thermostats were added to the building’s existing heating system, solar hot water collectors were installed on the building’s roof to heat domestic hot water, and a 4.4kW fixed-mount solar array was installed to offset the buildings electrical load. A HUGE THANKS goes out to the City of Nenana, the Nenana Tribal Council and to the following community members who helped us complete these projects. Jabob Kukes, Daniel Marks, Leon McElroy and Mike Pitka. POWER PRODUCED SINCE Feb 1, 2011: 3,620 kWh’s!! HEATING FUEL SAVED 10/1/2010-3/1/2011: 600 gals!! ! (5) The solar fluid is then pumped back to the collector to once again be reheated. This circulation loop will continue as long as there is heat to be drawn from the collector. During times when there is little or no sun, a backup heating system will be activated to provide adequate hot water. (1) When there is sufficient heat to be drawn from the collectors, a controller automatically activates pumps. (2) Heated solar fluid is then circulated from the collector, (3) through a heat exchanger where its heat is transferred to (4) water in the storage tank.

Northern Lights Anchorage, AK 99503 RE: Renewable Energy G t Fund Round V Alaska Energy Authority, As a small rural village in Alaska's interior Nenana is subject to some of the coldest temperature's in the state and heating fuel must be trucked in from FairbanIcs the regional hub, 57 miles away. The community of Nenana, the Nenana Native village and Toghotthele Corp are all seeking alternatives to heating oil. We're already resoarchin a tribal biomass project and would like to fully support the watershed council's work with Solar space heating for the Nenana student living center. The boarding school is an important part of this community and we hope that it will continue to thrive and teach our young people to be strong leaders and innovators. On behalf of the Native village of Nenana and the Toghotthele Native Corporation, I am pleased to write this letter in support of th efforts of the Yukon River Inter-Tribal Watershed Council to proceed with a ; proposal for a solar hot w t ter system on the Nenana Student Living Center through AEA's Renewable Energy Grant Fund Roan V. The Nenana Tribal Council and the community members of Nenana benefitted from a heating system upgrade and solar install on the roof of one of our community buildings last year and were impres ed with the watershed council's work, the energy savings and the amount of information that was proNiided to the community about the project. Both Toghotthele Native Corp and the Native Village of Nenana look forward to continuing our relationship with the Yul on River Inter-Tribal Watershed Council, during this project and on future ones. We encourage the YRIT NC's efforts to bring affordable energy solutions to the rural communities in Alaska. vv NesAM \)e__ Q:\r 'Te_ES 1 <54,4e...1 QaK.r Renewable Energy Fund Grant Application Round 5 AEA12-001 Grant Application Page 39 of 40 7/1//2011 Renewable Energy Fund Grant Application Round 5 AEA12-001 Grant Application Page 40 of 40 7/1//2011
