Summary

• Virginia is moving toward substantially higher battery-storage requirements, including reported goals of 4 gigawatts by 2030 and 20 gigawatts across short- and long-duration systems by 2045.
• The proposed NextEra-Dominion merger is closely tied to Virginia’s data center demand and could accelerate Dominion’s storage procurement and capital investment.
• The 150-megawatt, 600-megawatt-hour Prospect Power facility in Rockingham County was presented as the largest standalone battery project in the PJM region.
• Virginia and North Carolina cooperatives are using smaller batteries and microgrids to reduce peak costs, support solar, and limit outages during extreme weather.
• Commercial storage is expanding through energy-as-a-service models that remove upfront costs and combine batteries with solar and efficiency upgrades.
• Storage remains a practical grid-management tool for many adopters, even where emissions reduction is not the primary motivation.
• Implementation faces challenges including PJM interconnection delays, permitting, market rules, customer-rate concerns, and uncertainty over merger approval.
