CAISO notches record, serving 56.7% of demand with renewable energy in one day
California is already ahead of its aggressive 50% renewables target and a bill in the state legislature could, if passed, raise the bar to 100% by 2045.
But as renewable energy climbs as a percentage of the state’s overall production, some renewable output is going unused.
In a February memo CAISO warned that a “bountiful” hydro conditions and “significant” additional solar installations could result in the curtailment of between 6 GW and 8 GW of renewable capacity this spring.
The curtailments could create more opportunities for energy storage that could be used to store unused renewable production for use later in the day when the sun doesn’t shine or the wind stops blowing.
