The energy storage company replaced previously deployed lead-acid systems with advanced lithium-ion batteries, extending the resource’s operational lifetime and enhancing performance and reliability.
Darron Scott, President andCEO of Kodiak Electric Association, commented, “Younicos is a forward-thinking organization with proven technology that shares our belief in clean and affordable energy. As a cooperative, we’re owned by the island’s residents – who care about the environment and electricity rates. This upgraded battery system will ensure continued use of renewable energy, keeping our grid reliable and our costs down.”
In 2007, KEA set a goal to produce 95 percent of Kodiak Island’s energy from renewable sources by the year 2020, to greatly 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 U.S. cities to achieve over 99 percent 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 intelligently controlled battery system originally designed – and now upgraded – by Younicos.
