California nuke extension challenged in legislative proposal SACRAMENTO, Calif. (AP) — A proposal circulated Friday by California Democratic legislators would reject Gov. Gavin Newsom’s plan to extend the lifespan of the state’s last operating nuclear power plant — and instead spend over $1 billion to speed up the development of renewable energy, new transmission lines and storage to maintain reliable power in the climate change era. The legislative plan obtained by The Associated Press reveals mounting tension between the Democratic governor and some members of his own party over a politically volatile issue. The rift was revealed one week after Newsom proposed giving plant operator Pacific Gas Electric a forgivable loan up to $1.4 billion as part of a plan to keep the Diablo Canyon Nuclear Power Plant running beyond its scheduled closing by 2025. Newsom has argued that as hotter temperatures drive up the demand for power, the twin-domed reactors along the coast between Los Angeles and San Francisco would provide a necessary buffer against electrical blackouts, as the state transitions to power from solar, wind and other renewable energy sources.
