Equinor has launched the Citrus Flatts Energy Center in Cameron County, Texas, marking its largest battery storage project in the United States to date. The facility provides 100 megawatts of capacity and 200 megawatt-hours of energy storage. It was developed and is operated by East Point Energy, a subsidiary fully owned by Equinor, which acquired the site from Black Mountain Energy Storage in late 2023.
The project operates on a merchant basis within the ERCOT power market, meaning it earns revenue by trading electricity based on price fluctuations and providing grid services. Market operations are managed by Danske Commodities, an energy trading arm of Equinor. This is the second commercial battery project for East Point Energy, following the 10 megawatt Sunset Ridge Energy Center launched last year.
Equinor reports that its two Texas-based battery projects can collectively power approximately 30 000 homes for up to two hours. The company is also developing four additional battery projects in Virginia with a combined capacity of 80 megawatts and 160 megawatt-hours. These facilities are expected to begin operations in the PJM power market in early 2027.
The expansion of battery storage in Texas aligns with broader regional trends. According to the US Energy Information Administration, utility-scale solar generation in ERCOT is projected to reach 78 billion kilowatt-hours in 2026. Furthermore, total battery capacity in the ERCOT market is forecast to increase from approximately 15 gigawatts in 2025 to 37 gigawatts by the end of 2027.
