“Gas accounts for 40% of California’s grid. However, its use in April registered its lowest proportion in seven years.”

Then they are competing with peaking gas power plants. those are inefficent, but can start up and shut down quickly. However the cost of those is at about $151–198/MWh. per kWh.. So you need 2000 charge cycles to break even. Batteries also last a lot longer then that up to 10,000 cycles under optimal conditions.
