Equinor Starts 100 MW Citrus Flatts Battery in Texas, Its Largest US Storage Asset

Equinor has brought online Citrus Flatts, a 100 MW battery with 200 MWh of capacity, in Texas, the largest energy storage asset in the Norwegian company's United States portfolio.

The installation sits at Harlingen and was built by East Point Energy, a wholly owned Equinor subsidiary. It has entered commercial operation.

Citrus Flatts is the fifth storage facility Equinor has commissioned in the past four years.

East Point Energy's second operating project is Sunset Ridge, rated at 10 MW and 20 MWh. Together the two batteries can deliver energy matching the demand of roughly 30,000 households for a maximum of two hours.

Both sites trade in the ERCOT market in Texas, where storage is meant to stabilise the power system by absorbing surplus energy and releasing it at peak demand.

Four further storage projects are under development in Virginia, totalling 80 MW and 160 MWh. Commercial operation is scheduled for early 2027.

Equinor is a Norwegian energy company with roots in the oil and gas sector, developing technologies and operating offshore for more than 50 years. Alongside the US battery build-out, it is advancing offshore wind projects in Poland, including Baltyk 2 and Baltyk 3, and investing in onshore power and energy storage.
