Kotzebue has integrated Li-ion energy storage into its off-grid microgrid. The Saft solution is enabling the hybrid wind-diesel power system to achieve its full potential, providing cleaner, more reliable and less expensive power to a remote community of 3 700 people. Kotzebue is located 30 miles north of the Arctic Circle, far from the nearest transmission grid. Historically, KEA (Kotzebue Electric Association), the city’s electricity cooperative, has relied on diesel generators. However, since the late 1990s KEA has committed to making every effort to reduce its dependence on diesel and has invested in wind energy. But the intermittent nature of the wind meant that KEA still had to run its diesel generators, often resulting in curtailment when the wind turbines were providing their
