RWE has completed 360MWh of US BESS projects, including a 100MW/200MWh BESS and 300MWac PV projects in Sulphur Springs, Texas, and an 80MW/120MWh system paired with a 200MW PV project in Bastrop County. In Arizona, RWE has brought online the 10/40MWh BPES, 52.5MWac Mesquite 4 project. The projects will participate in ERCOT’s electricity market, and the PV output will be provided to specific companies. EARCOT is currently the most active US state for BESS deployments, with potential to overtake California’s roughly 7GW of grid-scale BESS when it hits 9.5GW in October. However, supply chain issues around balance-plant (BOP) equipment are still a major challenge. The 5th Energy Storage Summit USA will be held in Austin, Texas in 2024.
