Equinor Starts Operations at 100 MW / 200 MWh Citrus Flatts Battery in Texas
Equinor has started commercial operations at the 100 MW/200 MWh Citrus Flatts battery energy-storage project in Harlingen, Texas, making it the company’s largest US battery facility. The project was developed by East Point Energy, Equinor’s storage subsidiary, and represents East Point’s second operational asset after the 10 MW/20 MWh Sunset Ridge battery started operating in 2025. Together, the two Texas projects provide 110 MW/220 MWh of capacity and can supply electricity equivalent to around 30,000 homes for up to two hours. Both projects participate on a merchant basis in the ERCOT electricity market, with Equinor’s trading arm Danske Commodities supporting optimisation. Citrus Flatts is Equinor’s fifth battery project placed into commercial production in four years.
Engie Acquires 438 MW / 876 MWh Battery Project in Poland
Engie has acquired a 438 MW/876 MWh battery energy-storage project at Trębaczew in Poland’s Łódź province, substantially expanding its Polish flexibility portfolio. The project was originally developed by Mithra Energy and Futureal Investment Partners and is expected to reach ready-to-build status in the fourth quarter of 2026. Commercial operation is targeted for the first quarter of 2029. The two-hour BESS will provide balancing and flexibility services as Poland adds more wind and solar capacity and reduces dependence on coal generation. Together with other Engie storage assets in the country, the acquisition strengthens the French utility’s position in one of Europe’s fastest-growing battery markets. Transaction value was not disclosed.
ArcLight Commits $1 Billion to Launch US High-Voltage Transmission Company
ArcLight Capital Partners has committed $1 billion in equity to create Anchor Point Transmission, a new independent US transmission developer focused on high-voltage grid infrastructure. Anchor Point will develop, finance, own and operate transmission projects needed to connect new renewable generation, storage and growing electricity demand across US power markets. The investment is significant because grid congestion and slow interconnection have become major constraints on renewable-energy deployment. ArcLight brings experience investing in power and infrastructure assets, while Anchor Point is intended to target projects requiring large-scale private capital and long development horizons. The $1 billion commitment provides the new platform with substantial development and construction capacity as US electricity demand rises from data centres, manufacturing and broader electrification.
