Luminant has finished construction of large-scale battery energy storage project in Texas

Luminant, a subsidiary of US power company Vistra Energy Corp., announced that its »Upton 2« battery energy storage system project has finished construction and began operation. According to the company, the new battery system is the largest energy storage project in Texas and seventh largest in the United States. It is located on the site of Luminant's 180 MW »Upton 2« solar power plant in Upton County.
The 10 MW/42 MWh lithium-ion energy storage system captures excess solar energy produced at »Upton 2« during the day and can release the power in late afternoon and early evening, when energy demand of Electric Reliability Council of Texas (ERCOT) is highest. ERCOT operates the electric grid and manages the deregulated market for 75 percent of the state.
The battery system can also take advantage of low-priced grid power to charge the batteries to be available for higher demand periods. Vistra is also currently developing the world's largest battery energy storage project, the 300 MW/1,200 MWh storage system at its 2.5 GW »Moss Landing« natural gas powered electricity generation plant in California, scheduled for commercial operations in the fourth quarter of 2020.
