California electricity from natural gas, 2001 to 2025
California electricity from natural gas stood at 73,326 in 2025, down 15.4% on the previous period.
California generated 73,326 gigawatt hours of electricity from natural gas in 2025, down 15.4 percent on the year before. The window runs from 2001, when the figure was 111,932.
How it is measured
The series counts net generation, electricity actually delivered to the grid, from utility-scale plants of one megawatt and larger, across electric utilities, independent producers, and industrial generators. It is collected on the Energy Information Administration's Form EIA-923, the survey behind the Electric Power Monthly, reported as thousands of megawatt hours and shown here as gigawatt hours summed to years. Small-scale rooftop solar is estimated separately and is not included in series like this one.
What the curve shows
Generation data dates the energy transition more precisely than any announcement: what a grid actually runs on is here, year by year. This line is one of the decliners: from a peak of 120,426 GWh in 2014 to 73,326 now, a fall of 39 percent.
