California is making so much solar energy that large commercial operators are increasingly forced to stop production, raising questions about the state’s costly plan to shift entirely to carbon-free sources of electricity.

In the last 12 months, California’s solar farms have curtailed production of more than 3 million megawatt hours of solar energy, either on the orders of the state’s grid operator or because prices had plummeted because of the glut, according to an analysis of data by The Times.

The amount of curtailed solar power has more than doubled from 1.5 million megawatt hours in 2021, state records show, and is up eight times from levels in 2017.

The waste would have been even larger if California had not paid utilities in other states to take the excess solar energy, documents from the state’s grid operator show. That means green energy paid for by California electricity customers is sent away, lowering bills for residents of other states.

Arizona’s largest public utility reaped $69 million in savings last year by buying from the market California created to get rid of its excess solar power. The utility returned that money to its customers as a credit on their bills.
