The developer of a proposed solar farm in Iowa County is planning a second solar farm in Kenosha County that could feature the first utility-scale battery storage in Wisconsin. Chicago-based Invenergy last week submitted an engineering plan for a 200-megawatt solar farm with a 50-megawatt battery component.
That’s larger than any battery currently deployed on the nation’s power grid and the first in the state of Wisconsin, according to data from the U.S. Energy Information Administration. Invenergy has installed 31.5-megawatt batteries in Illinois and West Virginia, which account for most of the capacity in the company’s advanced storage portfolio.
Batteries enable renewable energy sources like wind and solar to deliver power on demand, similar to traditional fossil fuel generators. They can also contribute to grid stability and provide reserve capacity to meet peaks in demand…Read the full article at: http://ieefa.org/developer-invenergy-proposes-large-solar-plus-storage-project-in-wisconsin/
