California has so much excess electricity-generating capacity, the shutdown of San Onofre Nuclear power plant last week had no impact on wholesale electricity prices, data from the California Independent System Operator showed.
California has a huge amount of gas plant capacity that’s not running at any time during the day. Idling natural gas-fired turbines stepped up to meet the current demand.
Many Californians probably remember high power prices in 2001 and 2002 that led to rolling brownouts across the state. Since then, developers built generators that added thousands of megawatts of local capacity to the grid, and that power has been augmented in recent years by the construction of huge wind and solar generators.
