The Diablo Canyon Power Plant will close in 2030, unless state lawmakers grant it an extension.

A coalition of local officials wants California Gov. Gavin Newsom and legislative leadership to move quickly to extend the state’s sole nuclear power plant.

What happened: On Tuesday, 54 local elected officials sent an open letter, shared exclusively with POLITICO, to Newsom, Senate pro Tempore Monique Limón and Assembly Speaker Robert Rivas encouraging the trio to act within the final month of the legislative session to extend operations at the Diablo Canyon Power Plant.

Why it matters: The letter signals that the coalition of business associations, labor groups and elected officials pushing to extend Diablo Canyon’s operation beyond its current sunset date in 2030 still sees a window of opportunity to get a bill passed this session. Despite months of conversations on the topic, a legislative proposal has not yet emerged.

Context: The federal Nuclear Regulatory Commission in April gave Pacific Gas & Electric permission to operate Diablo Canyon, which it owns, through 2045. But to do so, the power company will also need permission from the state.
