The four battery utility-scale energy storage projects are the largest of their kind in Virginia and will total 16MW in capacity.
The $33 million, five-year pilot projects will include:
- Two 12MW battery systems at the Scott Solar facility, expected to be completed by the first quarter of 2021.
- A 2MW battery storage at a substation in the Town of Ashland, Hanover County and another 2MW battery at a substation in New Kent County.
The lithium-ion battery systems are part of the Grid Transformation and Security Act that enables companies to invest in 30MW of battery storage.
The projects will pave the way for additional energy storage needed to support the company's commitment to achieve net-zero carbon and methane emissions by 2050 and increase the renewables portfolio to ensure grid reliability.
Dominion Energy is currently the fourth-largest of any utility holding company in the nation when it comes to solar rollout.
"Dominion Energy will pilot these 16 megawatts of battery storage to better understand how best to deploy batteries across our system to integrate renewables and provide grid reliability by filling gaps due to the inherent intermittency of solar and wind power," said Mark D. Mitchell, Dominion Energy's vice president of generation construction. "These pilot projects will also help us learn how to incorporate this emerging technology into our overall strategy to achieve net-zero carbon dioxide and methane emissions."
