Construction is underway at RWE’s Crowned Heron 1 and 2 and Cartwheel battery storage systems in Texas, with commissioning planned for 2025. On completion these projects will add storage capacity of 450 MW and 900 MWh, and bring its total of battery storage projects under construction to 931 MW across California, Texas and Arizona. They will contribute significantly to the company’s global growth target for battery storage of 6 GW by 2030.
The three projects are designed to provide critical energy storage capacity to support the stability and resilience of the Electric Reliability Council of Texas (ERCOT) grid, an important resource as the state continues to deal with record-breaking peak power demand during extreme heat events.
Crowned Heron 1 and Crowned Heron 2 are both 150 MW (300 MWh) projects located in Fort Bend County, Texas. Construction of Crowned Heron 1 is expected to be completed in summer of 2025, with Crowned Heron 2 commissioning planned for the autumn of 2025.
The 150 MW (300 MWh) Cartwheel project is located in Sulphur Springs, Texas, where RWE also operates Bright Arrow, a 300 MW solar and 100 MW (200 MWh) project announced earlier this year. Construction of Cartwheel is expected to be completed in the summer of 2025.
