A 150 MW/300 MWh liquid-cooled battery storage project, named Revolution, has commenced operations in West Texas, supporting the Electric Reliability Council of Texas (ERCOT) grid. The two-hour Battery Energy Storage System (BESS) is among the largest in the U.S., aiding Texas’ transition from fossil fuel to renewable energy sources.
Revolution, equipped with 6,432 battery modules from Sungrow Power Supply Co., employs a liquid-cooled heat dissipation system for its lithium iron phosphate battery cells. This design ensures balanced temperatures and extends the battery life by two years while increasing the discharge capacity by 15%.
The Sungrow PowerTitan BESS uses 4D sensing technology to collect cell temperature and operating data, matching cooling capacity to reduce heat loss. Revolution is expected to provide flexibility for ERCOT’s transmission network, serving homes and businesses in West Texas.
Texas, with its expanding solar and wind generation fleet, leads in battery capacity additions, representing roughly half of the 300 utility-scale battery storage projects expected to come online in the U.S. by 2025. ERCOT has over 4 GW of battery storage capacity in operation, with ongoing planned projects to meet the growing demand for energy storage.
