The Texas grid has been buckling because of extreme weather events and rapidly increasing load. Texas broke electricity demand records 11 times last summer [2022] and 9 times this summer.
The rapid deployment of renewables and grid-scale batteries is saving the Texas grid from brownouts and blackouts.

Grid-scale batteries have also been saving California from blackouts. Back in 2020, the California grid wasn't able to handle the peak demand of 46.8 GW during a heat wave and resulted in blackouts. But in 2022, thanks to the rapid deployment of several GW of additional batteries, California weathered a peak of 51.4 GW without issue.
