Equinor has strengthened its US energy storage portfolio with the start of commercial operations at the Citrus Flatts battery energy storage project in Harlingen, Texas. Developed by East Point Energy, a wholly owned subsidiary of Equinor, the facility has a capacity of 100 MW/200 MWh. The project represents another major step in Equinor’s strategy to expand its position in the US power market.
With Citrus Flatts now operational, Equinor has brought five battery storage facilities into commercial production over four years. For East Point Energy, Citrus Flatts is its second operational project, following the 10 MW/20 MWh Sunset Ridge Energy Center, which began operations in Texas in 2025. The development further strengthens the company’s growing battery storage presence in the US.
Citrus Flatts and Sunset Ridge together provide 110 MW/220 MWh of energy storage capacity. According to Equinor, the two facilities can provide enough electricity to power around 30,000 homes for up to two hours within the ERCOT power market. Both projects will operate on a fully merchant basis, while Equinor’s integrated power-market capabilities and collaboration with Danske Commodities will support asset management and portfolio optimisation.
The Texas project also supports Equinor’s broader ambition to build a competitive and scalable onshore power business. Battery energy storage systems can store electricity when supply is available and release it when demand increases, helping improve grid flexibility and reliability. This capability is particularly important in Texas, where renewable power generation has expanded significantly, creating a growing requirement for flexible energy storage solutions.
East Point Energy said the Citrus Flatts project is also expected to generate millions of dollars in tax revenue for local priorities. The project comes as electricity demand continues to rise across Texas, while the state remains a major US market for both wind and solar power. Battery storage can help manage fluctuations in renewable generation and provide additional flexibility to the ERCOT electricity market.
Beyond Texas, Equinor is expanding its US battery storage pipeline in Virginia’s PJM power market. Construction is underway on four projects with a combined capacity of 80 MW/160 MWh, with commercial operations expected in early 2027. The latest developments underline Equinor’s continued focus on battery energy storage and its expanding role in the US power and renewable energy market.
