There is still a chance for California’s last remaining nuclear power plant to stay open.

Last Friday, more than 50 nuclear advocates testified in support of the Diablo Canyon nuclear power plant at a California Energy Commission workshop. Many spoke of the need for California to shore up its electricity grid in the face of coming heat waves and power outages. Others emphasized that closing the plant, which generates 2.2 GW of electricity and currently provides 8.6 percent of the state’s total supply and about 15 percent of its low-carbon electricity, would be devastating to California’s emission-reduction goals.

The Department of Energy yesterday announced that it has amended its Civil Nuclear Credit (CNC) Program guidance for the currently open award cycle and extended the deadline for credit applications from July 5 to September 6. The DOE was instructed to establish the $6 billion program by the Infrastructure Investment and Jobs Act, signed into law by President Biden last November.

Extending the operational life of California’s Diablo Canyon nuclear power plant beyond 2025—its scheduled year of retirement—would help the state meet its climate goals more quickly, more reliably, and more cheaply than allowing the facility to close, a new study has found.

According to Retaining Diablo Canyon: Economic, Carbon, and Reliability Implications, keeping the plant on line could not only substantially reduce California’s emissions, natural gas use, and electric power costs, but also help avoid blackouts.

Statement from American Nuclear Society President Steven Nesbit and Executive Director and CEO Craig Piercy:

Officials in California are planning to replace the electricity produced by the Diablo Canyon nuclear power plant, scheduled to shut down in 2025, “mostly with Wyoming coal-fired generation.” That claim is made in a post on the Capitol Weekly website written by Gene Nelson, a cofounder of Californians for Green Nuclear Power (CGNP). Nelson writes that although state officials are trying to hide this plan from the public, CGNP uncovered it by detecting four obscure clues in California Public Utilities Commission (CPUC) filings.

A recent article on a radio station website about an auxiliary feedwater (AFW) pump problem at the Diablo Canyon nuclear power plant led to information exchanges between a reporter, the American Nuclear Society, and nuclear advocates. The incident also involved a tweet by a member of the Union of Concerned Scientists.

The San Luis Obispo County Board of Supervisors earlier this week endorsed extending the life of Diablo Canyon—California’s last operating nuclear power facility—which owner and operator Pacific Gas and Electric Company has scheduled for permanent closure in 2025. The two-unit, 2,289-MWe plant is located in San Luis Obispo County, near Avila Beach.

The American Nuclear Society supports the continued operation of California's Diablo Canyon nuclear power plant. The premature shutdown of Diablo Canyon units 1 and 2, slated respectively in November 2024 and August 2025, will inflict grave harm to California's economy and environment.

Nunes

Rep. Devin Nunes (R., Calif.) introduced legislation last week that would keep California’s Diablo Canyon nuclear power plant in operation beyond its expected 2025 closure date. Dubbed the Clean Energy Production Act (H.R. 4394), the bill was introduced July 9 and referred to the House Energy and Commerce Committee.

Cosponsoring the measure is the remainder of the Golden State’s GOP contingent to the House: Reps. Ken Calvert, Mike Garcia, Darrell Issa, Young Kim, Doug LaMalfa, Kevin McCarthy, Tom McClintock, Jay Obernolte, Michelle Steel, and David G. Valadao.

La Grange Park, IL – The American Nuclear Society (ANS) has submitted comments to the Federal Energy Regulatory Commission (FERC) in favor of reconsidering the shortsighted decision to shutter prematurely California’s largest clean energy resource, Diablo Canyon nuclear power plant.

ANS filed the comments on Nov. 12 in favor of an Oct. 26 complaint by Californians for Green Nuclear Power against the regulatory approvals of the 2016 decision by Pacific Gas & Electric Co. to permanently shutter Diablo Canyon Units 1 and 2 in November 2024 and August 2025, respectively. The complaint (Docket No. EL21-13-000) asked FERC to investigate whether the decision shuttering Diablo Canyon violates grid reliability standards. ANS agrees with the complaint that FERC ought to consider fully the negative consequences and reliability risks posed by a premature retirement of Diablo Canyon.

A nuclear advocacy group is asking the Federal Energy Regulatory Commission to review the approval by California regulators of the decision by Pacific Gas and Electric in 2016 to prematurely retire its Diablo Canyon plant—the Golden State’s only remaining operating nuclear power facility—in 2025.

On October 26, the nonprofit organization Californians for Green Nuclear Power Inc. (CGNP) filed a 32-page complaint with FERC in the matter, listing as respondents the North American Electric Reliability Corporation (NERC), Western Electricity Coordinating Council (WECC), California Independent System Operator (CAISO), California Public Utilities Commission (CPUC), California State Water Resources Control Board (CSWRCB), and California State Lands Commission (CSLC).
