Renewable energy developer RWE has broken ground on three battery energy storage system (BESS) projects in Texas, growing the number of storage projects it has under construction in the U.S. to 931 megawatts (MW).

The company on Oct. 2 said the Crowned Heron 1, Crowned Heron 2 and Cartwheel 1 BESS projects in Texas will have a combined power capacity of 450 MW. Once online, the projects will help stabilize the Electric Reliability Council of Texas grid, while moving RWE closer to its global battery storage growth target of 6 gigawatts by 2030.

“These battery storage projects mark a significant step in our ongoing commitment to enhancing the energy infrastructure in Texas, while growing our energy storage portfolio,” said Hanson Wood, head of development, utility-scale renewables, for RWE Clean Energy. “When completed and operating, our Crowned Heron 1 and 2 and Cartwheel battery projects will serve as reliable energy storage solutions to enhance grid stability and support the state’s rapidly growing renewables sector.”

Located in Fort Bend County, Texas, Crowned Heron 1 is expected to be complete in the summer 2025 and followed that fall by Crowned Heron 2.

Cartwheel 1, set for commissioning in summer 2025, is located in Sulphur Springs, Texas, where the company also operates the 300-MW Bright Arrow solar farm with 100 MW of battery storage.

RWE’s other BESS projects under construction in the U.S. are located in Arizona and California.
