Dominion Energy Virginia announced four battery storage pilot projects for which it has sought SCC approval.

The four utility-scale battery storage pilot projects totaling 16 megawatts are enabled by the Grid Transformation & Security Act of 2018, which allows Dominion Energy to invest in up to 30 megawatts of battery storage pilot projects.

The four proposed Central Virginia-based lithium-ion projects will cost approximately $33 million to construct. Pending SCC approval, the pilots would be evaluated over a five year period once operational as currently expected in December 2020.

Two battery systems totaling 12 megawatts at the Scott Solar facility in Powhatan County will demonstrate how batteries can store energy generated from solar panels during periods of high production and release energy during periods when load is high or solar generation is low. It would also help optimize the power produced by the solar facility.

A 2-megawatt battery at a substation in Ashland will explore how batteries can improve reliability and save money on equipment replacement by serving as an alternative to traditional grid management investments such as transformer upgrades, necessary to serve customers during times of high energy demand.

A 2-megawatt battery at a substation in New Kent County serving a 20 megawatt solar facility will show how batteries can help manage voltage and loading issues caused by reverse energy flow, to maintain grid stability.

Separately, the company issued a Request for Proposals (RFP) seeking bids for up to 500 megawatts of solar and onshore wind generation in the state.
