GE’S Wind Turbines Cutting Diesel Generation in Alaska

September 23, 2010

Wind turbines supplied by GE are helping the city of Kodiak, on Kodiak Island off the southern coast of Alaska, reduce its use of diesel fuel and lower its energy costs, according to BusinessWire. The three GE 1.5-megawatt wind turbines were installed in 2009 by the Kodiak Electric Association (KEA), Kodiak Island''s electric utility, as a part of the Pillar Mountain Wind Project. After a year of successful operation, GE''s wind turbines have enabled KEA to avoid the use of 930,000 gallons of diesel fuel. The three GE wind turbines for the Pillar Mountain project have a total capacity of 4.5 MW, which equals approximately 25 percent of KEA''s peak load demands. In addition, the wind turbines have supplied roughly 9 percent of annual system generation for the island in the year that they have been operating. Prior to the installation of the wind turbines, KEA relied on diesel generation to provide much of the island''s peaking power. Prior to the installation of the wind turbines, all of the island''s power was provided by a two-unit hydroelectric plant and seven diesel generators.
