Provide a brief one paragraph description of the proposed project.
Thi s project consists of the installation and integration of 5 each Windm atic 175 turbines 95 kWe wind
turbines (490 kW) into the Naterqak Light Plant diese l power grid. The integration of this wind energy
includes the installat ion of load balancing boiler, 40 residential electric thermal storage (ETS) units,
wind diesel supervisory control and data acquisition system (WDSC), and improvements to the electrical
distribution system which include sectiona li zing, the replacement of 3 power poles and one distribution
transformer, as well as the extension of the distribution by 3 power poles to the wind site . The
proposed system is similar to those installed in the neighboring villages of Kongiganak, Kwigillingok and
Tuntutuliak.
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, local jobs created, etc.)
This project u ses wind energy to displace diesel fuel resu lting in lower energy costs, creation of local
j obs, deferment of construction of additional bulk fuel storage, and improved generation efficiency.
Fuel displacement for power generation: (48,715 ga llons displaced with wind)
• Fuel displacement for home heating (8720 gallons displaced with wind)
• Fuel displacement in heat recovery loop (1600 gallons displaced with wind)
• Deferred bulk fuel storage( city usage 130,000 gallons, usable storage capacity 72,000)
Increase distribution efficiency ( 5% estimated reduction in line los s, current line loss exceed 300,000
kilowatt hours,)
Creation of local jobs, ( 2 part time wind techs, $45,000)
The wind energy project is estimated to annually displace 60700 gallons of diesel fuel. 48,715 used for power
generation, 8700 gallons of home heating fue l, and 3250 gallons are displaced in the powerplant heating loop .
The utility saving that which can be passed onto the customers include reduced fu el purcha ses of $243,575
annua lly based on a $5.00/gallon (conceptual design report attached) ave ra ge price for fue l over the life of the
project, and increased revenues 288,335 kWhrs ETS sa les, @ $.10/kWhr = $28,833 and 107,243 kWhrs to the heat
loop@ $$.10/kWhr = $10,724.
Lower heating costs : Homeowners who have the electric thermal storage devices can expect annual savi ng of 220
gallons of heating fuel . This fue l is displaced usi ng the electric th ermal storage device s to capture surplus wind
energy generated from the wind system. Excess wind energy is sold by the electric utility for $.10 per kilowatt
hour. This is equivalent which is equivalent to approximately $2.90/gallon heating fuel. Homeowner use on
average 766 gallons of heating fuel, for which they currently pay $7.10 per ga llon to have delivered. ISER
estimated lon gterm fue l costs of $6 .93/gallon was for the purposes of this application. Annual savings for a
re sidential customer with an wind enabled electric thermal storage device is estimated to be $1122. (8 .00 -2 .90)x
220 = $1122 annual savings . 40 residential ETS units are proposed for this project, offering a co mbine savi ngs of
$44,800 .
