UPDATE 7/10/2026
Investor-owned utilities across the eastern United States, the Southeast, and Texas are investing in battery energy storage, solar-plus-storage, mobile storage, and grid modernization projects to improve reliability, manage peak demand, support renewable energy, and strengthen resilience.
These projects show that energy storage is becoming a mainstream utility resource, not just a future concept.
Dominion Energy – VirginiaDominion Energy Virginia has advanced battery storage projects as part of its grid transformation work, including pilot projects designed to test utility-scale battery storage in Virginia. The company has also deployed mobile battery energy storage as a cleaner alternative to diesel generators for events, remote work sites, EV support, utility backup, and emergency management needs.
