NRC clears 20-year renewal for Diablo Canyon, but 2030 state cap holds
The Nuclear Regulatory Commission has granted Pacific Gas and Electric Company a 20-year license renewal to keep running Diablo Canyon Power Plant. It was the 100th operating license the NRC has renewed for a U.S. power plant.
Regulators found the plant safe and environmentally sound to run for another two decades, according to Power Engineering. Running the reactors past 2030 still needs the California Legislature to act.
The plant produces more than 2,200 MW and ranks as California's largest source of clean energy, according to Power Engineering.
Earlier federal money set the plant on this path. The Biden administration finalized a USD 1.1 billion aid package at the start of 2024 to keep Diablo Canyon generating to at least 2030, according to Power Engineering.
The NRC decision hands PG&E a federal license good for 20 years, yet state law still limits operations to 2030. Lawmakers in the state capital would have to vote again before the utility could run the twin-unit plant through the full federal term.
At more than 2,200 MW, the plant supplies the single largest amount of low-carbon capacity on the state grid, so a 2030 shutdown would leave that output to be replaced from other sources.
