Dominion Begins Operations on Largest Battery Storage Pilot Challenge in Virginia


These battery energy storage enclosures are operational at Scott Solar facility in Powhatan Count.

Dominion Energy Virginia has opened its largest operational battery energy storage pilot undertaking, which was just lately energized on the Scott Solar facility in Powhatan County. The firm has two different battery storage pilot initiatives in its portfolio: a 2 MW battery in New Kent County that was commissioned in late February and a 2 MW battery in Hanover County that’s scheduled to develop into operational later this yr. All three initiatives have been authorised by the Virginia State Corporation Commission (SCC) in February 2020.

The three utility-scale battery storage pilot initiatives totaling 16 MW are the primary of their variety in Virginia. Dominion Energy is utilizing lithium-ion batteries to higher perceive how this rising know-how might be built-in into numerous functions to profit clients.

“Battery storage is an integral component to the clean energy transition in Virginia, supporting grid reliability for our customers during periods of high demand and by helping to fill gaps due to the inherent intermittency of solar and wind power,” says Ed Baine, president of Dominion Energy Virginia. “These battery systems will help us better understand how best to deploy utility scale batteries across our service territory to support our goal of net zero emissions by 2050.”

The three central Virginia-based initiatives present key info on distinct use instances for batteries on the energy grid. Annual updates on the pilots’ efficiency shall be reported to the SCC.

Three unbiased 4-hour battery techniques totaling 12 MW on the Scott Solar facility will present priceless info on the proficiency of battery know-how to retailer energy generated from solar panels during times of excessive manufacturing and launch energy during times when load is excessive or solar technology is low. It would additionally reveal how effectively a battery can optimize power manufacturing of the solar facility.

A 2 MW, 2-hour 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, 2-hour 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 circulate, to keep up steady power supply to clients.

In addition to those three pilot initiatives, Dominion Energy has obtained regulatory approval from the Virginia SCC for the 20 MW Dry Bridge storage in Chesterfield County and 50 MW of storage at Dulles International Airport in Loudoun County.
