Jan. 4 — 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 in ERCOT is highest. The battery system can also take advantage of low-priced grid power – during times of high wind output, for example – to charge the batteries to be available for higher-demand periods, explains Luminant.
