February 26 (Renewables Now) - US utility Dominion Energy Inc (NYSE:D) has secured regulatory approval to install four battery storage systems in Virginia with a combined capacity of 16 MW.
The pilot project was greenlighted by the State Corporation Commission (SCC). Its goal will be to assess how the energy storage technology can be integrated into various applications and how it can help the utility overcome obstacles related to the fluctuation of wind and solar power generation. The testing period will be five years, Dominion said on Tuesday.
Under the plan, Dominion Energy Virginia will add two lithium-ion batteries of 12 MW in total at the site of its Scott Solar facility in Powhatan County, while two systems of 2 MW each will be installed in Hanover County and New Kent County, respectively. All of them are expected to go live in the first quarter of 2021. The total investment in the project is estimated at around USD 33 million (EUR 30.3m).
"Experience from these pilot projects will enable storage to complement or serve as an alternative to traditional grid enhancements needed to maintain reliable service for our customers as we work to integrate renewables and improve grid resiliency," said Mark D Mitchell, Dominion's vice president of generation construction. In Virginia, the company has the right to invest in up to 30 MW of pilot battery storage projects.
