Xcel Energy’s “Wind-to-Battery” project is currently being tested on a Minnesota wind farm. The company believes that the 80-ton battery will power 500 homes for 7 hours when fully charged. The battery’s 20 50-kilowatt modules together are roughly the size of two semi- trailers and can store 7.2 megawatt-hours of electricity.
