California PUC launches rulemaking to consider extension of Diablo Canyon nuclear plant

Kavya Balaraman, Jan. 13, 2023

Dive Brief:

  • California regulators on Thursday voted to open a rulemaking to consider extending the operations of the 2.2-GW Diablo Canyon nuclear power plant, the last operational nuclear facility in the state.
  • The rulemaking stems from legislation approved last September, which among other things required the California Public Utilities Commission to issue a decision by the end of this year establishing new retirement dates for the two units of the nuclear plant.
  • The Diablo Canyon nuclear plant, which is owned and operated by Pacific Gas & Electric, is currently licensed to operate until 2024 and 2025 for each of its two units respectively. In 2018, state regulators approved a plan to retire the facility once these licenses expire.

Dive Insight:………………………..

Under SB 846, Diablo Canyon Unit 1 could be kept running through Oct. 31, 2029, and Unit 2 until Oct. 31, 2030.

In November, PG&E applied to the U.S. Nuclear Regulatory Commission to keep the plant running until 2030. 

Under the umbrella of its new rulemaking, the CPUC could either authorize extending operations at the plant through 2029 and 2030, or establish earlier retirement dates.

…………………………. California stakeholders remain split on the state’s reversal on the future of the Diablo Canyon nuclear plant.

“The rush to keep Diablo Canyon running beyond 2025 is not only dangerous, but will set back California’s drive to make solar and wind the prevailing sources of electricity in the state,” Ken Cook, president of the Environmental Working Group, said in an emailed statement. ………………….

  1. The Diablo Nuclear Power Plant is built near a seismic fault. The longer a nuclear power remains in operation, the more brittle it becomes. The excess neutrons, bombard the containment and control rod apparatus. The Diablo Nuclear Power should be permanently shut down and decommissioned. It is too dangerous, too expensive and totally unnecessary for our energy needs. Go to the Website of the Solutions Project for the plans for the United States, all 50 of the United States of America. We “will not starve and freeze in the dark,” nor “wreck our economy in the process.”
