and services you will use to accomplish the project. Include any partnerships or commitments
with other entities you have or anticipate will be needed to complete your project. Describe any
existing contracts and the selection process you may use for major equipment purchases or
contracts. Include brief resumes and references for known, key personnel, contractors, and
suppliers as an attachment to your application.
The School District will select a qualified turnkey solutions provider contractor to
implement this project.
3.4 Project Communications
Discuss how you plan to monitor the project and keep the Authority informed of the status.
Please provide an alternative contact person and their contact information.
Quarterly reports will be provided to the Authority, including schedule and cost updates.
3.5 Project Risk
Discuss potential problems and how you would address them.
Solar PV - Solar PV is a well established technology that has proven its success in the widest
set of circumstances possible (outer space, marine, residential rooftops, etc.) and requires
minimal maintenance. Since there are no moving parts, the biggest issue is inverter
replacement. To address this risk, the common 10 year warranty on inverters will be extended
to 20 years to better match the life of the PV modules.
Heat recovery - Heat recovery from exhaust air is a well established technology that has
proven its success over the past 15+ years and requires minimal maintenance. Since there are
no moving parts, and it requires minimal maintenance, the risk to the owner is minimal.
Project Delivery — The School District will utilize an energy performance contract to deliver the
project, which will provide guaranteed results and a fixed price. This procurement method will
limit risk to the District and provide the highest likelihood of executing and completing a
successful project with measurable results to report back to the community and State.

SECTION 4 - PROJECT DESCRIPTION AND TASKS `I
• The levelof information will vary according to phase(s) of the project you propose to
undertake with grant funds.
• If some work has already been completed on your project and you are requesting funding for an
advanced phase, submit information sufficient to demonstrate that the preceding phases arer
satisfied and funding for an advanced phase is warranted.
4.1 Proposed Energy Resource
Describe the potential extent/amount of the energy resource that is available.
Discuss the pros and cons of your proposed energy resource vs. other alternatives that may be
available for the market to be served by your project. For pre -construction applications, describe the
resource to the extent known. For design and permitting or construction projects, please provide
feasibility documents, design documents, and permitting documents (if applicable) as attachments to
this application.
Solar PV - We selected PV because it best fits the requirements of the SD. We initially considered
wind power as well, but decided against it, due to the lack of small turbines that can withstand our
climate in the long term. Solar is scalable, allowing us to adjust the size to the average demand of
the SD.
The solar resource for this location is expected to be 3.11 kWh/m2/day.
Heat recovery — Heat recovery technology was chosen as the school district has high amount of
ventilation needs due to number of occupants in the building and the amount of ventilation air
required to meet code. The weather in this part of Alaska is cold, and requires significant heating.
Mean heating degree days in Naknek is roughly 11,200 F and average sensible heating load is
318,000 Btu/cfm (output from the heating delivery system).
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.
Solar PV - The School District currently gets all of its electricity and heat from the Naknek Electric
Association. The energy generated onsite will offset utility purchases.
Heat recovery —The School District currently uses 100% outside air throughout most of the District
facilities. There is currently no heat recovery equipment in place.
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.
At times, the PV system may generate more electricity than what is needed at the School
District. We will coordinate with Naknek Electric Association for how excess generation will
be used in the community and how it will impact energy costs for the School District when
demand is greater than production.

4.2.3 Existing Energy Market
Discuss existing energy use and its market. Discuss impacts your project may have on energy
customers.
The main customer affected by this project is the School District. In case of excess
generation, the utility provider may be able to offer other customers to benefit from clean
solar power.
4.3 Proposed System
Include information necessary to describe the system you are intending to develop and address
potential system design, land ownership, permits, and environmental issues.
4.3.1 System Design
Provide the following information for the proposed renewable energy system:
A description of renewable energy technology specific to project location
Optimum installed capacity
Anticipated capacity factor
Anticipated annual generation
• Anticipated barriers
Basic integration concept
Delivery methods
The system will consist of a 50 kW ground -mounted PV array. Each kW is expected to
generate about 847 kWh in Year 1, assuming an orientation due south and 40 degree tilt.
Annual generation is estimated at 42,350 kWh in Year 1.
After 20 years, output will still exceed 80% of the output in Year 1. Solar PV is a very
established technology, so no barriers are anticipated. Integration will be done via the
inverter, and the vast majority of the power generated will be used on -site.
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.
The PV system will be installed on land owned by the SD, so no land ownership issues are
anticipated. 50 kW require about 15,000 sqft of unshaded land, which is available to the south
of the school buildings.
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
Due to the absence of moving parts and emissions permitting for PV projects is fairly simple.
