en.Wedoany.com Reported - U.S. energy infrastructure developer Elevate Infrastructure, together with investor ArcLight Capital Partners, has completed and commissioned the Prospect Power battery energy storage system in northern Virginia. Located in the town of Timberville, the project has a capacity of 150 megawatts/600 megawatt-hours, making it the largest standalone battery energy storage system in Virginia and the largest integrated energy storage project within the 13-state power coordination region covered by PJM Interconnection. Originally developed by Swift Current Energy, the system was brought online amid accelerating construction of AI data centers in Virginia and continuously rising electricity demand.
ArcLight Managing Partner Angelo Acconcia noted that the company has over 20 years of experience in energy infrastructure. Acconcia believes that Prospect Power is precisely the type of infrastructure needed in the current market. As the energy industry enters its next growth phase in 2026, trends such as AI infrastructure, manufacturing reshoring, and electrification are jointly driving accelerated electricity demand growth. Battery energy storage will play a greater role in providing grid capacity and reliability, with Elevate at the forefront of this transformation. Elevate officials stated that the project provides critical flexible capacity for the Mid-Atlantic region.
Virginia Chief Energy Officer Josephus Allmond stated that projects like Prospect Power help the state maintain an affordable, reliable, and resilient grid. As the national grid continues to face pressure, large-scale battery energy storage projects will receive priority attention. Allmond added that utility-scale battery storage is becoming a key component of the state's energy strategy, both maximizing the value of existing infrastructure and providing the flexibility needed to meet growing demand. He mentioned that Governor Spanberger recently signed legislation encouraging the development of more battery storage projects across the state, and Prospect Power demonstrates forward-looking investments that support economic growth and long-term energy reliability.
Prospect Power has entered into a 15-year power purchase agreement with Dominion Energy Virginia, which will fully underwrite the project. Cedric Green, Senior Vice President of Generation at Dominion Energy Virginia, stated that the project will help the company ensure reliable electricity is available when and where customers need it. The project is also expected to bring revenue sharing and property tax-related benefits to Rockingham County. As a sponsor of the annual county fair, Prospect Power aims to integrate Elevate into the Northern Virginia community. PJM Interconnection Chief Operating Officer Stu Bresler stated that battery storage is playing an increasingly important role in supporting a reliable, resilient, and diverse grid. This project increases battery storage capacity within the PJM region by more than 50%, marking a significant milestone for energy storage development in the area. As demand continues to grow, such resources will further enhance grid flexibility, helping to maintain system reliability.
