A behind-the-scenes effort to persuade California lawmakers to extend operations at the state’s only nuclear power plant became public Thursday.

What happened: A coalition of business, labor and energy groups announced the creation of Diablo Canyon 2045, an alliance of 25 organizations that hope to push legislators to extend the Diablo Canyon Power Plant’s operations beyond its current 2030 limit to 2045.

Why it matters: The announcement signals that Diablo Canyon supporters intend to pressure the California Legislature to pass a bill this year to extend operations.

Context: The coalition includes the Bay Area Council and a bevy of other regional business groups, the International Brotherhood of Electrical Workers local 1245, which represents workers at the plant, and pro-nuclear advocacy groups like Mothers for Nuclear and the Clean Air Task Force.
