Equinor launches its largest US battery storage facility in Texas
The 100 MW/200 MWh Citrus Flatts facility began commercial operations to trade power on the state's merchant grid.
The short version
- Equinor subsidiary East Point Energy brought the 100 MW/200 MWh Citrus Flatts Energy Center online in Harlingen, Texas.
- The storage asset will operate on a fully merchant basis within the ERCOT power market rather than under a long-term utility contract.
- Equinor's energy trading arm, Danske Commodities, is managing market operations and optimization for the project.
- The company's next US battery storage assets, totaling 80 MW/160 MWh, are currently under construction in Virginia and slated for 2027.
