On Wednesday night, minutes before the state’s grid operator went into emergency mode to make sure it would have enough power to meet high demand during another triple-digit day, batteries provided more electricity to Texas homes and businesses than ever before.
A small but growing number of batteries sent 2,172 megawatts to the grid on that critical evening — just under 3% of the overall supply. One megawatt can power about 200 homes when demand is high, so batteries dispatched enough electricity to power roughly 434,000 homes at that moment.
