Kotzebue Wind Power

Kotzebue Electric Association (KEA) was a pioneer of wind power above the Arctic Circle. Its first three 66 kilowatt turbines became operational in 1997, and wind later supplied about a quarter of its total energy.[1]

Early years

The utility’s board committed $250,000 for initial research, and a study found that 20 turbines could be installed without affecting the nearby Air Force DEW Line radar site. Three Atlantic Orient Corporation 66 kilowatt turbines became operational in 1997, and the first ten were fully installed by 1999. One early turbine ran for 21 years and was the oldest operating wind turbine above the Arctic Circle before it was decommissioned.[1]

Expansion

In 2012 two EWT 900 kilowatt turbines were installed, each equal to about 22 of the older machines and standing 250 feet tall with variable speed. Wind supplied about 25 percent of the utility’s total energy by 2017 and at times up to 75 percent of its load.[1]

Storage and influence

After long-duration flow batteries failed, the utility adopted a 1.2 megawatt lithium-ion battery to address stability issues. It bought the first commercial Northwind 100 turbine, which helped open the market for that model, and the Alaska Village Electric Cooperative later bought many Northwind turbines. The utility also added solar photovoltaic systems.[1]
