California's utility batteries can supply 5GW for a few hours. In the morning today they were charging at about 2.8GW and then early evening output peaked at 3.5GW.
They're basically competing with natural gas peaking plants. You could argue they're buying natural gas power in the morning for cheap and selling it in the early evening when it's expensive.
