California Keeps Diablo Canyon Nuclear Reactor Running 5 More Years
The Iron Law of Electricity for the win: San Luis Obispo County is now looking to add additional reactors to the plant.
There have been a couple of fascinating developments that touch upon two subjects I cover for Legal Insurrection: California and nuclear power.
A few years ago, California was asking electric vehicle drivers not to charge their cars. The grid was weak, as energy consumption was high because of a summer heat wave (or as climate cultists like to refer to it, a “heat dome”).
So, as presumptive 2028 candidate Gavin Newsom prepares for his campaign’s official launch, there is some pre-planning to avoid the embarrassment of statewide brownouts or blackouts during his run. Such an event would give Newsom’s adversaries both within and outside the Democratic Party a big target that would resonate with many Americans, who no longer believe the “climate crisis” narrative.
At the time of the original report, there were plans to close the state’s last remaining nuclear power plant: Diablo Canyon. Miraculously, the plant has had its life extended by a whopping 5 years.
California environmental regulators on Thursday struck a landmark deal with Pacific Gas & Electric to extend the life of the state’s last remaining nuclear power plant in exchange for thousands of acres of new land conservation in San Luis Obispo County.
PG&E’s agreement with the California Coastal Commission is a key hurdle for the Diablo Canyon nuclear plant to remain online until at least 2030. The plant was slated to close this year, largely due to concerns over seismic safety, but state officials pushed to delay it — saying the plant remains essential for the reliable operation of California’s electrical grid. Diablo Canyon provides nearly 9% of the electricity generated in the state, making it the state’s single largest source.
The Coastal Commission voted 9 to 3 to approve the plan, settling the fate of some 12,000 acres that surround the power plant as a means of compensation for environmental harm caused by its continued operation.
Interestingly, Newsom cited summer heat waves as one of the key reasons for the extension.
The governor and lawmakers say the reason they wanted to keep Diablo Canyon running is because of its impact on the power grid. Gov. Newsom said that during extreme heat waves, Diablo Canyon is important to keeping the grid stable while avoiding blackouts.
A study done by MIT and Stanford in 2021 showed that keeping Diablo Canyon running could cut carbon emissions by 10% and save over $2 billion in system costs. According to the investigation, the study started a campaign by people who are pro-nuclear to get the plant to remain open.
“Diablo Canyon is the backbone of the California clean, reliable electrical system,” said Richard St. Onge, a consultant with the American Nuclear Society. “If you look at the numbers out there, California gets 10% of its electricity from Diablo Canyon.”
Watts Up With That contributor Eric Worrall humorously notes the obvious conclusion about the likely consequence of California pursuing its green energy schemes.
I’m shocked California has wavered in their commitment to renewables like this.
Keeping this plant open will be seen as some as an admission that California’s enormous renewable investments are not delivering stable electricity supplies.
If hundreds of billions of dollars investment in renewables and batteries is not enough to prevent blackouts during periods of energy stress, surely the solution is more hundreds of billions of dollars of green energy investment.
As a bonus, San Luis Obispo County wants to study another way the facility’s power-generating life might be extended…by adding new nuclear reactors.
On Tuesday, the San Luis Obispo County Board of Supervisors approved a $25,000 contract with Solestiss, a Maine-based nuclear energy consulting firm, to assess the economic impact of keeping Diablo Canyon open for another 20 years.
A $10,000 portion of the study will investigate the feasibility of developing a new advanced large-scale nuclear reactor and small modular reactors.
Small modular reactors — or SMRs — are reduced, theoretically easier-to-assemble reactors that can be more conveniently located near power-hungry areas than traditional plants, but this emerging technology does not yet exist in the United States beyond the design stage.
Once again, it is the Iron Law of Electricity for the win.

I’m curious about the Philips 66 Los Angeles oil refinery that is supposed to close this month.
Curious about what? (Just curious about your curiosity is all.)
What > I < am curious about: is any of the refinery machinery salvageable? Is any of it of such value that transport to another state for use in another refinery is worth it.
Theoretically yes.
Practically, probably not.
Because this wasn’t a sudden thing. They’ve known for years that
So first from a business perspective, they have already made plans to remove anything that is worth it to another state (most likely a whole host of things that will be used as replacement parts for other similar setups, or used as emergency maintenance replacements for failures).
Additionally, from an engineering perspective, ANY long term maintenance project would be cancelled, and even short term stuff would prioritize short-term costs over long term health.
So they already plan to remove anything worthwhile, AND the entire plant will have a huge amount of cancelled maintenance.
Think of it like this, if the refinery were a car, they knew they were going to scrap it, so they haven’t changed the oil or oil filters for 2 years, haven’t replaced engine spark plugs, and rather than fix a transmission fluid oil leak just said ‘just put more fluid in when it runs out’.
Then they planned to completely remove the engine and battery before scrapping it.
Sure, theoretically you COULD salvage the car, but you’ve built up so much maintenance debt that it would be cheaper to just get a new one.
CA hypocrisy on display. They’ll still adhere to the green mantra while keeping the plant open even though the green mantra is bs.
PG&E shouldn’t have had to cut any deal with the environazis. Their response should have been: Extend the life of the plant or watch your grid crash and burn. Your choice.
Half of them would have said, “I’m already sold, don’t keep selling.”
I wish California would shut this plant down, the voters want renewable energy so give it to them, they voted for the consequences too. We the people need to have California as the canary in the coal mine for Green Agenda madness, logically it should be pushed to the hilt. $20 dollar gas and $10 dollar per watt electricity should work well
Strange deal as PG&E was in the drivers seat. They should have demanded 12,000 acres and a chicken in every pot.
I’m confused as I thought Tonopah was the answer to everyone’s prayers?
The Wholesale Adoption of Artificial Intelligence is projected to require 200 1GW data centers. The USA will be forced to increase its electrical generation capacity by 50%. That means every available source needs to be pursued and nothing can be retired.
Nuclear, coal, natural gas, hydro and even alternative energy must all be ramped up. Or, electric prices will skyrocket and your Air Conditioner will cost too much to use.
Alternative energy (wind and solar) should not be part of any increase in electricity production. They are very expensive forms of sporadic electricity production, and use up capital that can be better used for traditional forms of electricity production.
Yes, better to spend capital on stuff that always works
Sorry, meant an up vote.
Thanks.
Require the data centers to build their own sources of power. When data center is idle, sell excess power to the grid.
There are many leftists who would love to see that happen (their own creature comforts exempt, natch!). What good is being the elite if you don’t get to stomp on the faces of the proles?
All of this new energy doesn’t go to the consumer, but to the powerful and controlling. No guessing who gets the increased power bill. The law of conservation of momentum…. for every advance in Al, there is an equal advance in AS… artificial stupidity.
On the other hand we could require new large power consumers to fund construction of the generation capacity and transmission lines to support the electricity requirements they say they need.
Wait, who’s donating those thousands of acres? PG&E, or the state? If it’s the state that wants the plant to remain open, then surely it should be the one to pay whatever price this might require. Though why it should require a price is another question; but however that is answered, it should be the state paying PG&E to remain open, not the other way around.
What harm? Nuclear power has the lowest impact on the environment of any means of power production.
Again, so it’s beneficial to the environment, not harmful.
When fantasy meets reality, reality always wins.
Well, I guess we get to see exactly how dedicated they actually are to this whole green energy thing
They will be so desperate for fossil fuels that they will soon be burning down the Natural History Museums.
Will these new nuclear reactors end up like the high-speed train the greeniac politicians pushed? Way over budget with practically nothing to show for it (aside from rich politicians and contractors)?
Communism doesn’t work – a lesson the California communists refuse to learn.
If left to the people who know nukes, these will work well. But what politician smelling money and power will not intervene… as you say… The 5th generation nuke are good design. Three Mile Island will also be coming back. Note….. living 1 mile downwind of TMI for a year immediate and following the meltdown… the total radiation dose was less than living in Denver.
brownouts and blackouts
thats gotz to be ray cist
Me and my wife are California natives born in the late 50s. Our sons in the 80s. We left as a family in 96 as my business moved us to the east coast, but many of our family and friends are in all parts of the state.
I am an Electrical Engineer and retired in 21 but worked mostly in Telecom, but setup many sites around the world and domestically. This included power design for the sites.
In California I have seen solar and wind farms to be pushed but they do not last and they do not produce the power at all times. Wind Farms tend to hurt birds and each Wind Turbine requires individual wiring that a power plant does not need. California also removed some dams to make some of the Tribes happy but it affects power output. California killed their Nuclear plants except for the last one, which due to brownouts and blackouts they now want to expand.
The best producing for power is Nuclear, Natural Gas, Hydro, Oil, and Coal. The problem we have in the USA is much of electric grid needs to be updated and we need to add more Nuclear Plants.
What you have said is all good common sense. That will NEVER work in California!
You’d think the federal government could prevent the closure of any power plant on national security grounds.
Insane politicians in a few States shouldn’t be allowed to put the national grid at risk.
