California lawmakers are circulating draft legislation that might keep the state’s last working nuclear plant, Diablo Canyon, open past its deliberate 2025 closure date, though there are nonetheless vital logistical and political challenges forward earlier than that would occur.
The plan to shut Diablo Canyon has been underway since 2016. But as the dire signs of local weather change — warmth and drought — have been bearing down laborious on the state, and delays have slowed the development of wind and photo voltaic vitality sources, lawmakers and representatives for native utility PG&E are reconsidering.
The Diablo Canyon energy plant at present provides 8.6% of the state’s electrical energy and 17% of the state’s zero-carbon electrical energy provide. The two working reactors are scheduled to be retired November 2, 2024, and August 26, 2025. But California is will in all probability not have the ability to ramp up its wind and photo voltaic renewable vitality sources quick sufficient to meet that capability.
“Two issues modified since last 12 months,” David Victor, professor of innovation and public coverage at the School of Global Policy and Strategy at UC San Diego, advised CNBC. “One is the grid operators have centered much more on reliability and the challenges in sustaining grid reliability. An unreliable grid shouldn’t be solely unhealthy for the economic system but additionally very unhealthy for politicians.”
California Governor Gavin Newsom additionally indicated some willingness for conserving the nuclear energy plant open, and that helped catalyze these newest strikes.
“The different factor that modified, which might be much more essential, is it the governor signaled his curiosity in a attainable extension with an offhand comment to the Los Angeles Times. That was just a few months in the past and touched off principle of research and lobbying,” Victor mentioned. “That has culminated in as we speak’s proposal.”
Draft legislation in California legislature
A replica of the draft legislation was circulated to lawmakers on Thursday, in accordance to Gov. Newsom’s workplace, and was shared with CNBC on Monday.
The draft legislation says that the California vitality grid goes to battle to keep up with demand.
“The impacts of local weather change are occurring sooner and with better depth and frequency than anticipated, inflicting unprecedented stress on California’s vitality system,” the draft legislation reads. “These impacts are concurrently driving increased demand as extra intense and frequent warmth waves hit California and the Western area and decreasing provide as drought circumstances impression hydropower manufacturing and fires threaten electrical infrastructure.”
It then cites the problem of ramping up renewable vitality sources in time to make the transition.
“Because of provide chain disruptions, the impression of tariff disputes, and different delays in set up of latest clear vitality technology and storage methods, together with photo voltaic and wind tasks with battery storage, there may be substantial threat that inadequate new clear vitality provides will likely be on-line in time to guarantee electrical energy system reliability when the Diablo Canyon powerplant is scheduled to be decommissioned,” the legislation draft reads.
If California doesn’t prolong operations of Diablo Canyon, then the state will find yourself relying on sources of vitality that launch greenhouse gasses, which trigger local weather change to speed up, the draft legislation argues.
The proposal would keep unit 1 open till October 31, 2029, and unit 2 till October 31, 2030. After 5 years, the state would assess whether or not the models ought to keep open for an additional 5 years, with a ultimate expiration set for October 31, 2035, in accordance to a memo about the legislation shared by the governor’s workplace with CNBC on Monday.
Newsom’s workplace identified that it has been working to make it sooner to carry renewable sources of vitality on-line.
“In June, the state took motion to streamline allowing for clear vitality tasks to carry extra renewable vitality technology and storage on-line,” the governor’s workplace mentioned in a written assertion supplied to CNBC.

Not simple to reverse course
Victor is in favor of extending Diablo Canyon’s life. But he additionally is aware of that lots of effort went into the shutdown plan.
“And they’re going to really feel betrayed. So the politics of this might be very nasty. And the utility is caught proper in the center — with large dangers,” Victor advised CNBC.
While conversations in the California legislature are a essential step for initiating the processes to keep Diablo Canyon open, there are lots of logistical procedures and staffing wants which would wish to be addressed to keep the plant open.
“It’s laborious to assess the odds that the plant will likely be prolonged, particularly for the full 10 years. A 12 months in the past I put the odds at about 5 % or so. Now I put the odds at about 25 % to 35 %,” Victor advised CNBC.
“The new proposal, together with federal incentives, will assist quite a bit. But folks appear to neglect that there is a entire lot of equipment that wants to occur to keep a plant open. An extension wants to be filed with a Nuclear Regulatory Commission. Crucially, staff are wanted and till now just about all the staff had been centered on getting completely different jobs and the utility was serving to them discover these jobs,” Victor mentioned.
“You can think about fixing all these issues individually however doing it all of sudden on a decent schedule will likely be difficult,” he mentioned.
If Diablo had been to get strive to get its working license prolonged, the state of California would mortgage the utility working the plant, PG&E, as a lot as $1.4 billion to assist with the prices related to relicensing, in accordance to the memo from the governor’s workplace. Also, PG&E might apply to get federal cash from the U.S. Department of Energy’s $6 billion program passed as part of Bipartisan Infrastructure Law which was supposed to protect the present U.S. fleet of nuclear energy reactors. “The proposed language gives a pathway for relicensing at the U.S Nuclear Regulatory Commission in order that PG&E might apply for this funding,” the memo from the governor’s workplace says.
On July 28, PG&E announced its second quarter financials. And in the dialogue of the utility firm’s monetary outcomes, the CEO, Patricia Ok. Poppe, addressed Diablo Canyon’s future.
“Earlier this 12 months, Governor Newsom reached out to ask us to consider conserving Diablo Canyon open past its scheduled retirement in 2024 and 2025 to assist the capability and reliability of the state’s electrical provide system,” Poppe mentioned. “We’re exploring the chance of conserving this plant open for California’s profit. It shouldn’t be a straightforward possibility and it’ll require a lot coordination between the state, a number of regulatory our bodies and PG&E in addition to many others impacted by the end result of this resolution.”
Poppe mentioned that if Diablo Canyon is to be prolonged, PG&E wants to know quickly as a result of there are a slew of steps it has to take to have the ability to keep the plant on-line.
“We’ve received an actual sense of urgency so as to transition from being in a decommissioning posture to a life extension posture. So the most essential factor to us proper now could be that we get certainty on the decision-making. We have to safe casks. We have to order gasoline. There are some very near-term gadgets,” Poppe mentioned. “The actions that we would wish to take if, in truth, we alter the posture of the plant.”
Reversing course could be a problem, however Poppe additionally famous a change in the state’s emotions about nuclear vitality. “We like the proven fact that that plant’s worth is being acknowledged by the state. There appears to be type of a shift in the perspective about the position that nuclear can play in a GHG-free economic system,” Poppe mentioned.
She mentioned PG&E would strive to get entry to federal funds. “We do assume that the DOE funding is a chance and positively the state has expressed curiosity in maximizing that and ensuring that Diablo Canyon will get included in the DOE’s program to prolong the lifetime of nuclear,” Poppe mentioned. “Again nationally, I believe there’s been an actual shift in perspective about the worth of those baseload nuclear amenities. And so, on condition that, we’re simply going to proceed to work via the financials, and that will likely be second to ensuring that the plant is prepared and secure and in a position to function for the state.”
But the clock is ticking. Legislation has to be handed by the finish of August, after which signed into legislation in September, Poppe mentioned.
