2026-04-02【核电】原计划2025底退役的美国加州Diablo Canyon核电站获批延寿20年

ederal officials have renewed the license for Diablo Canyon, California's last remaining nuclear power plant, guaranteeing it will remain open for another 20 years until 2045. The plant, located on the San Luis Obispo coast, provides 9% of the state's electricity and was previously scheduled to close in 2025. However, after recent heat waves strained the power grid, state leaders pushed to keep the facility running as California continues to expand renewable energy sources.

Why it matters

Diablo Canyon's continued operation is a significant milestone for California's energy landscape and climate goals. The plant provides a steady source of carbon-free power during the state's transition to renewable energy, helping to ensure grid reliability and avoid blackouts. However, some anti-nuclear groups remain concerned about earthquake risks and the plant's environmental impact, setting up a potential battle over its long-term future.

The details

The Nuclear Regulatory Commission granted Diablo Canyon a 20-year license renewal on Thursday, allowing the plant to operate until 2045. This comes after state lawmakers passed a law in 2022 directing the plant's owner, PG&E, to pursue the license extension and providing a $1.4 billion state loan to cover upgrade and relicensing costs. To operate beyond 2030, PG&E will need further approval from the state Legislature, which could face opposition from anti-nuclear groups.

In 2020 and 2021, heat waves strained California's power grid and caused brief blackouts.

In 2022, Gov. Gavin Newsom signed a law directing PG&E to pursue Diablo Canyon's license extension.

On Thursday, the Nuclear Regulatory Commission granted Diablo Canyon a 20-year license renewal until 2045.
