Younicos has completed the installation and commissioning of an upgraded 3MW battery-based energy storage system on Kodiak Island, Alaska. The energy storage company replaced previously deployed lead-acid systems with advanced lithium-ion batteries.

In 2007, Kodiak Electric Association (KEA) set a goal to produce 95 percent of Kodiak Island’s energy from renewable sources by the year 2020, to reduce reliance on diesel fuel and lower the cost of generation to customers. The utility reached that goal ahead of schedule in 2012. Since 2015, Kodiak Island has been one of only five US cities to achieve over 99% of its generation through renewable resources. The use of increased amounts of wind energy to reach the goal while maintaining reliability was enabled by the battery system originally designed, and now upgraded, by Younicos.
