Dominion Energy acquires Virginia’s largest battery storage project


US utility Dominion Energy has acquired a 20MW/80MWh energy storage project from developer East Point Energy.

Once operational in 2022, the project is expected to be the largest in the Commonwealth of Virginia.

The Dry Bridge energy storage project is located in Chesterfield County and powers approximately 5,000 households at peak output.

The utility will leverage the plant to provide services including firming of intermittent renewables, grid resilience and capacity, as well as ancillary services to the PJM wholesale market.

Dominion is planning to leverage energy storage to expand its use of renewable energy capacity to meet baseload demand. The company, in its 2020 Clean Energy Request for Proposals with the state regulator, has asked permission to build or procure 2.7GW of energy storage capacity by 2035.

The utility is confident that expanding its storage capacity will enable the company to provide 100% of its electricity using renewables by 2045. Both renewable and energy storage will also enable consumers to be provided with less expensive electricity.

In its latest filing with the state regulator, Dominion Energy has proposed the largest expansion of solar and energy storage capacity in Virginia. The utility is proposing to add to its portfolio of assets; 11 utility-scale solar projects, two small-scale distributed solar projects, one combined solar and storage project, and one stand-alone energy storage project.

If approved, the plan will increase Dominion Energy’s capacity by 1,000MW of carbon-free electricity, enough to power more than 250,000 homes at peak output. The projects will generate more than $880 million in economic benefits across Virginia and will support nearly 4,200 clean energy jobs.
