Energy Northwest Tests Wind Power Storage System

Posted: Updated:

KENNEWICK, Wash. (AP) - Researchers in the Pacific Northwest are testing and evaluating a new power storage system that could help store excess electricity generated by the region's many wind farms.
The system at south-central Washington's Nine Canyon Wind Project includes enough lithium ion batteries to store 500 kilowatt hours of power. That's enough energy for about a dozen homes for several hours.
Supporters say it's a first step toward being able to store renewable energy that is produced when demand is low - say, at night, when most people are sleeping - to be used where it's most needed during the daytime.
Partners in the project include system developer Powin Energy, Pacific Northwest National Laboratory, the Bonneville Power Administration and Energy Northwest, the public-power consortium that operates the wind farm.
