The federal Nuclear Regulatory Commission has renewed the operating license for the Diablo Canyon nuclear power plant, allowing it to continue generating electricity in California through at least 2030. The plant was originally scheduled to close in 2025, but lawmakers extended the deadline by five years in 2022 due to the state's ongoing energy needs.

Why it matters

Diablo Canyon is California's last remaining nuclear power facility, providing a significant source of carbon-free electricity for the state. The license extension helps ensure grid reliability and maintain the state's progress toward renewable energy goals as it phases out fossil fuels.

The details

The Nuclear Regulatory Commission's decision on Thursday grants Diablo Canyon a 5-year extension to its operating license, allowing the plant to continue running through 2030. This overrides the previous plan to shutter the facility in 2025, which was part of a deal struck between the plant's owner, Pacific Gas & Electric, and environmental groups.
