D•Prospect Power, a 150-MW/600-MWh standalone battery facility in Rockingham County, Virginia, began operations under a 15-year power purchase agreement with Dominion Energy Virginia. As the largest storage asset in the PJM region, it boosts regional battery capacity by over 50%, enhancing grid flexibility and reliability.
1. Prospect Power Commences Operations
On June 11, Elevate Infrastructure and ArcLight Capital Partners brought the 150-MW/600-MWh Prospect Power battery storage facility online in Rockingham County, marking the largest standalone project in Virginia and the broader PJM Interconnection region.
2. 15-Year PPA with Dominion Energy Virginia
Prospect Power’s full output is contracted under a 15-year power purchase agreement with Dominion Energy Virginia, ensuring fast-response power delivery and revenue stability for the facility through long-term off-take commitments.
3. Regional Grid Impact
By increasing PJM’s battery storage capacity by over 50%, the project provides flexible resources to balance supply and demand, manage peak loads and strengthen overall grid reliability as electricity demand accelerates.
4. Strategic Growth and Future Projects
The commissioning aligns with Elevate’s strategy to develop utility-scale battery assets in high-growth markets; the company recently secured a 150-MW/600-MWh project in New Jersey and closed a $50 million financing facility for solar and storage, indicating further expansion in grid-scale storage.
