EDP Renewables North America (EDPR NA) has secured a long-term capacity tolling agreement with Dominion Energy to develop an 85MW/340MWh battery energy storage system (BESS) in Virginia, US.

EDPR NA, a subsidiary of Portuguese utility EDP Renewables, revealed on Monday (16 September) that the project would reach commercial operations in 2027. No other details on the BESS were released.

The organisation added that the deal will see EDPR NA “continue to reinforce its commitment with innovation and the development of new technologies”.

Dominion Energy stated in April that it was seeking proposals for solar, wind and energy storage projects in the state. Indeed, a statement released by the company revealed that accept five types of proposals, including new solar PV projects and new PV solar generation co-located with energy storage. It will also look at new onshore wind, onshore wind co-located with energy storage and standalone energy storage.

The projects will help the utility reach its goal of net zero greenhouse gas emissions by 2050, part of which is deploying 3.1GW of energy storage by 2035.

In July 2024, Energy-Storage.news reported that EDPR NA had inaugurated the 200MW/40MW Scarlet I solar-plus-storage project in Fresno County, California.

The project’s solar and energy storage capacity is contracted under two power purchase agreements (PPAs) with local Californian electricity suppliers: Ava Community Energy for 100MW of solar capacity and 30MW of energy storage and San José Clean Energy for the remaining 100MW of solar and 10MW of energy storage.

EDPR NA already has 248MW of operating renewable energy assets in California, notably the Lone Valley PV project in San Bernadino County. It is developing the 300MW Sandrini Solar Park in Kern County, California, for which EDP inked a PPA with oil giant Shell in 2022. Since that deal was signed, Sandrini Solar’s capacity has been expanded from 200MW to 300MW.
