New battery backup for Kodiak utility passes test

Kodiak utility officials say a new battery backup for the city’s power grid has passed initial tests.

The Kodiak Daily Mirror said the Kodiak Electric Association recently installed a pair of battery banks at a substation on Pillar Mountain, located within city limits.

The battery banks are a key component of the expanded Pillar Mountain wind farm, acting as a sort of surge protector.

The batteries are intended to balance the ebb and flow of wind energy and they also can provide power if a diesel generator suddenly falters.

KEA president Darron Scott announced the test results last week at the association’s regular monthly board meeting.

The tests mimicked a major event involving a sudden loss of power equivalent to the production of two and a half wind turbines.
