Ratepayers, and as less and less fossil gas is needed (because batteries [1] [2] [3] and more renewables), their costs for generation and electrical supply should go down. CAISO, California's grid operator, currently has 61.7GW of hybrid solar/battery projects and 42GW of battery storage [4] in its interconnect queue. CAISO current installed capacity is 21.5GW of solar and 13.39GW of battery storage, compared to ~30GW of fossil gas generation [5].
