Dominion Energy Virginia has asked the State Corporation Commission to approve four pilot battery storage projects totaling 16 MW.
Two projects, with a combined capacity of 12 MW, at the Scott Solar facility in Powhatan County, will demonstrate how batteries can store solar energy during high production periods and release energy during peak demand periods, according to an Aug. 6 news release.
A 2-MW battery at a substation in Ashland will explore reliability as an alternative to traditional grid management investments like transformer upgrades. A 2-MW battery at a substation in New Kent County, serving a 20-MW solar facility, will show how batteries can manage voltage and loading issues caused by reverse energy flow.
Under Virginia's Grid Transformation & Security Act of 2018, Dominion Energy can invest in up to 30 MW of battery storage pilot projects.
