Toksook Bay (Wind)

Toksook Bay is a coastal community located on the Etolin Strait, approximately 115 miles northwest of Bethel. This system was installed in the summer and fall of 2006 as part of a complete plant retrofit by the Alaska Village Electric Cooperative. The town has a population of approximately 600 people, but it is interconnected through the land-based interties to the nearby towns of Tununak and Nightmute, bringing the total population served to over 1,160. The average load of all three communities is just under 370 kW. The power system includes three Northern Power Systems Northwind 100kW turbines, diesel engines, and a computer-controlled resistive heater supplying community heating loads.

The array of wind turbines has had an average net capacity factor of 26.0% from August 2007 to July 2008 and good first year turbine availability of 92.4%. The average penetration for this system has been over 24.2%, with average monthly penetrations over 30% during winter months, when stronger winds prevail. In the year ending September 2008, almost 700 MWhrs of electricity were generated by wind, offsetting almost 46,000 gallons of fuel.
