Freshly switched on in Texas: Equinor’s 100 MW battery behemoth

Citrus Flatts Storage Unit Begins Commercial Operations

According to НВ — Техно: Citrus Flatts, a storage facility in Harlingen, Texas, was officially commissioned at noon on September 5 by East Point Energy, an Equinor Group company. With 100 MW of power and 200 MWh of storage capacity, it is East Point Energy’s second operating storage asset. For Equinor overall, it represents the fifth commercial energy-storage system launched in four years.

Together with Sunset Ridge, a 10 MW/20 MWh station that came online last year, Citrus Flatts can supply around 30,000 households with power for two hours. No long-term offtake contracts are tied to either facility; Danske Commodities optimizes their power trading.

Beyond Texas: East Point Energy’s pipeline grows

East Point Energy is also expanding into another state. Equinor is developing storage assets in Virginia on the PJM electricity market, with four projects totaling 80 MW of capacity and 160 MWh of storage expected to start up in early 2027.

Texas, the nation’s largest oil-and-gas state, is also a renewable-energy leader. It generates more wind electricity than any other U.S. state, and its solar market is quickly becoming one of the world’s largest.

“Millions of dollars in tax revenue will go toward local priorities through this project. With electricity demand climbing sharply across Texas, it will strengthen the grid and help maintain affordable energy for families and businesses,” said Andrew Fucal.

The Citrus Flatts launch highlights the rising role of energy storage in keeping power systems stable as demand grows. With renewables booming in Texas, such facilities can reshape the region’s energy mix, lessening dependence on traditional generation and supporting better environmental outcomes.
