Dominion Energy Virginia obtained approval from the State Corporation Commission (SCC) to maneuver ahead with four battery storage pilot projects to pave the way for additional energy storage technology wanted to help the corporate’s dedication to realize web zero carbon and methane emissions by 2050, improve in renewables and to enhance grid reliability.

The 4 utility-scale lithium-ion battery storage pilot initiatives totaling 16 MW are the most important initiatives of their form in Virginia.

These initiatives are enabled by the Grid Transformation & Security Act of 2018, which permits Dominion Energy to put money into as much as 30 MW of battery storage pilot initiatives. As the corporate continues to extend its solar fleet – currently the fourth-largest of any utility holding company in the nation – and construct out its offshore wind development off the coast of Virginia Beach, the corporate is trying for new and revolutionary methods to retailer the renewable energy it produces to keep up dependable service to clients.

“Dominion Energy will pilot these 16 MW 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,” mentioned Mark D. Mitchell, Dominion Energy’s vice chairman of era development. “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.”

“Energy storage is emerging as a critical component to meeting our customers’ needs and providing continued grid stability,” mentioned Joe Woomer, Dominion Energy’s vice chairman of grid and technical options. “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.”

The 4 Central Virginia-based initiatives will value roughly $33 million to assemble and can present key info on distinct use instances for batteries on the energy grid. The pilots shall be evaluated over a five-year interval as soon as operational, presently anticipated to be in first quarter of 2021.

  • Two battery techniques totaling 12 MW at the Scott Solar facility in Powhatan County will present priceless info on the proficiency of battery technology to retailer energy generated from solar panels in periods of excessive manufacturing and launch energy in periods when load is excessive or solar era is low. It would additionally reveal how properly a battery can optimize power manufacturing of the solar facility.
  • A 2-MW battery at a substation within the Town of Ashland, Hanover County, will bolster the present grid capability to serve clients throughout instances of excessive energy demand with out the necessity to interact in wholesale tools upgrades.
  • A 2-MW battery at a substation in New Kent County serving a 20-MW solar facility will display how batteries will help handle voltage and loading points brought on by reverse energy move, to keep up steady power supply to our clients.
