Loblaws powers down its stores

Ontario Nuclear Refurbishment Economic Impact powers growth as Bruce Power's MCR and OPG's Darlington unit 2 refurbishment drive jobs, supply-chain spending, medical isotopes, clean baseload power, and lower GHG emissions across Ontario and Canada.

Key Points

It is the measured gains from Bruce Power's MCR and OPG's Darlington refurbishment in jobs, taxes, and clean energy.

✅ CAD7.6B-10.6B impact in Ontario; CAD8.1B-11.6B nationwide.

✅ Supports 60% nuclear supply, jobs, and medical isotopes.

✅ MCR and Darlington cut GHGs, drive innovation and supply chains.

The 13-year Major Component Replacement (MCR) project being undertaken as part of Bruce Power's life-extension programme, which officially began with a reactor taken offline earlier this year, will inject billions of dollars into Ontario's economy, a new report has found. Meanwhile, the major project to refurbish Darlington unit 2 remains on track for completion in 2020, Ontario Power Generation (OPG) has announced.

The Ontario Chamber of Commerce (OCC) said its report, Major Component Replacement Project Economic Impact Analysis, outlines an impartial assessment of the MCR programme and related manufacturing contracts across the supply chain. The report was commissioned by Bruce Power.

"Our analysis shows that Bruce Power's MCR project is a fundamental contributor to the Ontario economy. More broadly, the life-extension of the Bruce Power facility will provide quality jobs for Ontarians, produce a stable supply of medical isotopes for the world's healthcare system, and deliver economic benefit through direct and indirect spending," OCC President and CEO Rocco Rossi said."As Ontario's energy demand grows, nuclear truly is the best option to meet those demands with reduced GHG [greenhouse gas] emissions. The Bruce Power MCR Project will not only drive economic growth in the region, it will position Ontario as a global leader in nuclear innovation and expertise."

According to the OCC's economic analysis, the MCR's economic impact on Ontario is estimated to be between CAD7.6 billion (USD5.6 billion) and CAD10.6 billion. Nationally, its economic impact is estimated to be between CAD8.1 billion and CAD11.6 billion. It estimates that the federal government will receive CAD144 million in excise tax and CAD1.2 billion in income tax, while the provincial government will receive CAD300 million and CAD437 million. Ontario’s municipal governments are estimated to receive a collective CAD192 million in tax.

The nuclear industry currently provides 60% of Ontario’s daily energy supply needs, with Pickering life extension plans bolstering system reliability, and is made up of over 200 companies and more than 60,000 jobs across a diversity of sectors such as operations, manufacturing, skilled trades, healthcare, and research and innovation, the report notes.

Greg Rickford, Ontario's minister of Energy, Northern Development and Mines, and minister of Indigenous Affairs, said continued use of the Bruce generating station which recently set an operating record would create jobs and advance Ontario’s nuclear industrial sector. "It is great to see projects like the MCR that help make Ontario the best place to invest, do business and find a job," he said.

The MCR is part of Bruce Power's overall life-extension programme, which started in January 2016. Bruce 6 will be the first of the six Candu units to undergo an MCR which will take 46 months to complete and give the unit a further 30-35 years of operational life. The total cost of refurbishing Bruce units 3-8 is estimated at about CAD8 billion, in addition to CAD5 billion on other activities under the life-extension programme, which is scheduled for completion by 2053.

Darlington milestones

OPG's long-term refurbishment programme at Darlington, alongside SMR plans for the site announced by the province, began with unit 2 in 2016 after years of detailed planning and preparation. Reassembly of the reactor, which was disassembled last year, is scheduled for completion this spring, and the unit 2 refurbishment project remains on track for completion in early 2020. At the same time, final preparations are under way for the start of the refurbishment of unit 3.

"We've entered a critical phase on the project," Senior Vice President of Nuclear Refurbishment Mike Allen said. "OPG and our project partners continue to work as an integrated team to meet our commitments on Unit 2 and our other three reactors at Darlington Nuclear Generating Station."

A 350-tonne generator stator manufactured by GE in Poland is currently in transit to Canada, where it will be installed in Darlington 3's turbine hall as the province also breaks ground on its first SMR this year.

The 10-year Darlington refurbishment is due to be completed in 2026, while the province plans to refurbish Pickering B to extend output beyond that date.

California Income-Based Electricity Rates propose a fixed monthly fee set by income as utilities and the CPUC weigh progressive pricing, aiming to cut low-income bills while PG&E, SCE, and SDG&E retain usage-based charges.

Key Points

CPUC plan adds income-tiered fixed fees to lower low-income bills while keeping per-kWh usage charges.

✅ Adds fixed monthly fees by income to complement per-kWh charges

✅ Cuts bills for low-income households; higher earners pay more

✅ Utilities say revenue neutral; conservation signals preserved

California’s electric bills — already some of the highest in the nation — are rising as electricity prices soar across the state, but regulators are debating a new plan to charge customers based on their income level. 

Typically what you pay for electricity depends on how much you use. But the state’s three largest electric utilities — Southern California Edison Company, Pacific Gas and Electric Company and San Diego Gas & Electric Company — have proposed a plan to charge customers not just for how much energy they use, but also based on their household income, moving toward income-based flat-fee utility bills over time. Their proposal is one of several state regulators received designed to accommodate a new law to make energy less costly for California’s lowest-income customers.

Some state Republican lawmakers are warning the changes could produce unintended results, such as weakening incentives to conserve electricity or raising costs for customers using solar energy, and some have introduced a plan to overturn the charges in the Legislature.

But the utility companies say the measure would reduce electricity bills for the lowest income customers. Those residents would save about $300 per year, utilities estimate.

California households earning more than $180,000 a year would end up paying an average of $500 more a year on their electricity bills, according to the proposal from utility companies. 

The California Public Utilities Commission’s deadline for deciding on the suggested changes is July 1, 2024, as regulators face calls for action from consumers and advocates. The proposals come at a time when many moderate and low-income families are being priced out of California by rising housing costs.  

Who wants to change the fee structure?
Lawmakers passed and Gov. Gavin Newsom signed a comprehensive energy bill last summer that mandates restructuring electricity pricing across the state. 

The Legislature passed the measure in a “trailer-bill” process that limited deliberation. Included in the 21,000-word law are a few sentences requiring the public utilities commission to establish a “fixed monthly fee” based on each customer’s household income. 

A similar idea was first proposed in 2021 by researchers at UC Berkeley and the nonprofit thinktank Next 10. Their main recommendation was to split utility costs into two buckets. Fixed charges, which everyone has to pay just to be connected to the energy grid, would be based on income levels. Variable charges would depend on how much electricity you use.

Utilities say that part of customers’ bills still will be based on usage, but the other portion will reduce costs for lower- and middle-income customers, who “pay a greater percentage of their income towards their electricity bill relative to higher income customers,” the utilities argued in a recent filing. 

They said the current billing system is unjust, regressive and fails to recognize differences in energy usage among households,

“When we were putting together the reform proposal, front and center in our mind were customers who live paycheck to paycheck, who struggle to pay for essentials such as energy, housing and food,” Caroline Winn, CEO of San Diego Gas & Electric in a statement. 

The utilities say in their proposal that the changes likely would not reduce or increase their revenues.

James Sallee, an associate professor at UC Berkeley, said the utilities’ prior system of billing customers mostly by measuring their electric use to pay for what are essentially fixed costs for power is inefficient and regressive. 

The proposed changes “will shift the burden, on average, to a more progressive system that recovers more from higher income households and less from lower income households,” he said.

Renewables 2020 Global Status Report highlights renewable energy gaps beyond power, urging decarbonization in heating, cooling, and transport, greener COVID-19 recovery, market reforms, and rapid energy transition to cut CO2 emissions and fossil fuel dependence.

Key Points

REN21's annual report on renewable energy progress and policy gaps across power, heating, cooling, and transport.

✅ Calls for decarbonizing heating, cooling, and transport.

✅ Warns COVID-19 recovery must avoid fossil fuel lock-in.

✅ Urges market reforms to boost energy efficiency and renewables.

Growth in renewable power has been impressive over the past five years, with over 30% of global electricity now coming from renewables worldwide. But too little is happening in heating, cooling and transport. Overall, global hunger for energy keeps increasing and eats up progress, according to REN21's Renewables 2020 Global Status Report (GSR), released today. The journey towards climate disaster continues, unless we make an immediate switch to efficient and renewable energy in all sectors in the wake of the COVID-19 pandemic.

"Year after year, we report success after success in the renewable power sector. Indeed, renewable power has made fantastic progress. It beats all other fuels in growth and competitiveness. Many national and global organisations already cry victory. But our report sends a clear warning: The progress in the power sector is only a small part of the picture. And it is eaten up as the world's energy hunger continues to increase. If we do not change the entire energy system, we are deluding ourselves," says Rana Adib, REN21's Executive Director.

The report shows that in the heating, cooling and transport sectors, the barriers are still nearly the same as 10 years ago. "We must also stop heating our homes and driving our cars with fossil fuels," Adib claims.

There is no real disruption in the COVID-19 pandemic

In the wake of the extraordinary economic decline due to COVID-19, the IEA predicts energy-related CO2 emissions are expected to fall by up to 8% in 2020. But 2019 emissions were the highest ever, and the relief is only temporary. Meeting the Paris targets would require an annual decrease of at least 7.6% to be maintained over the next 10 years, and UN analysis on NDC ambition underscores the need for faster action. Says Adib: "Even if the lock-downs were to continue for a decade, the change would not be sufficient. At the current pace, with the current system and current market rules, it would take the world forever to come anywhere near a no-carbon system."

"Many recovery packages lock us into a dirty fossil fuel economy"

Recovery packages offer a once-in-a-lifetime chance to make the shift to a low-carbon economy, and green energy investments could accelerate COVID-19 recovery. But according to Adib there is a great risk for this enormous chance to be lost. "Many of these packages include ideas that will instead lock us further into a dirty fossil fuel system. Some directly promote natural gas, coal or oil. Others, though claiming a green focus, build the roof and forget the foundation," she says. "Take electric cars and hydrogen, for example. These technologies are only green if powered by renewables."

Choosing an energy system that supports job creation and social justice

The report points out that "green" recovery measures, such as investment in renewables and building efficiency, are more cost-effective than traditional stimulus measures and yield more returns. It also documents that renewables deliver on job creation, energy sovereignty, accelerated energy access in developing countries, and clean, affordable and sustainable electricity for all objectives worldwide, alongside reduced emissions and air pollution.

"Renewables are now more cost-effective than ever, and recent IRENA analysis shows their potential to decarbonise the energy sector, providing an opportunity to prioritize clean economic recovery packages and bring the world closer to meeting the Paris Agreement Goals. Renewables are a key pillar of a healthy, safe and green COVID-19 recovery that leaves no one behind," said Inger Andersen, Executive Director of the UN Environment Programme (UNEP). "By putting energy transition at the core of economic recovery, countries can reap multiple benefits, from improved air quality to employment generation."

This contrasts with the true cost of fossil fuels, estimated to be USD 5.2 trillion if costs of negative impacts such as air pollution, effects of climate change, and traffic congestion are counted.

Renewable energy systems support energy sovereignty and democracy, empowering citizens and communities, instead of big fossil fuel producers and consumers. "When spending stimulus money, we have to decide: Do we want an energy system that serves some or a system that serves many?", says Adib. "But it's not only about money. We must end any kind of support to the fossil economy, particularly when it comes to heating, cooling and transport. Governments need to radically change the market conditions and rules and demonstrate the same leadership as during the COVID-19 pandemic."

The report finds:

Total final energy demand continues to be on the rise (1.4% annually from 2013 to 2018). Despite significant progress in renewable power generation, the share of renewables in total final energy demand barely increased (9.6% in 2013 to 11% in 2018). Compared to the power sector, the heating, cooling and transport sectors lag far behind (renewable energy share in power, 26%, heating and cooling, 10%, transport, 3%).

Today's progress is largely the result of policies and regulations initiated years ago and focus on the power sector. Major barriers seen in heating, cooling and transport are still almost the same a decade on. Policies are needed to create the right market conditions.

The renewable energy sector employed around 11 million people worldwide in 2018

In 2019, the private sector signed power purchase agreements (PPAs) for a record growth of over 43% from 2018 to 2019 in new renewable power capacity.

The global climate strikes have reached unprecedented levels with millions of people across 150 countries. They have pushed governments to step up climate ambitions. As of April 2020, 1490 jurisdictions - spanning 29 countries and covering 822 million citizens - had issued "climate emergency" declarations, many of which include plans and targets for more renewable-based energy systems.

While some countries are phasing out coal, examples such as Europe's green surge show how renewables can soar as emissions fall, yet others continued to invest in new coal-fired power plants. In addition, funding from private banks for fossil fuel projects has increased each year since the signing of the Paris Agreement, totaling USD 2.7 trillion over the last three years.

"It is clear, renewable power has become mainstream and that is great to see. But the progress in this one sector should not lead us to believe that renewables are a guaranteed success. Governments need to take action beyond economic recovery packages. They also need to create the rules and the environment to switch to an efficient and renewables-based energy system, and action toward 100% renewables is urgently needed worldwide. Globally. Now." concludes Arthouros Zervos, President of REN21.

US SF6 Emissions Decline as NOAA analysis and EPA mitigation show progress, with atmospheric measurements and Greenhouse Gas Reporting verifying reductions from the electric power grid; sulfur hexafluoride's extreme global warming potential underscores inventory improvements.

Key Points

A documented drop in US sulfur hexafluoride emissions, confirmed by NOAA atmospheric data and EPA reporting reforms.

✅ NOAA towers and aircraft show 2007-2018 decline

✅ EPA reporting and utility mitigation narrowed inventory gaps

✅ Winter leaks and servicing signal further reduction options

A new NOAA analysis shows U.S. emissions of the super-potent greenhouse gas sulfur hexafluoride (SF6) have declined between 2007-2018, likely due to successful mitigation efforts by the Environmental Protection Agency (EPA) and the electric power industry, with attention to SF6 in the power industry across global markets. 

At the same time, significant disparities that existed previously between NOAA’s estimates, which are based on atmospheric measurements, and EPA’s estimates, which are based on a combination of reported emissions and industrial activity, have narrowed following the establishment of the EPA's Greenhouse Gas Reporting Program. The findings, published in the journal Atmospheric Chemistry and Physics, also suggest how additional emissions reductions might be achieved. 

SF6 is most commonly used as an electrical insulator in high-voltage equipment that transmits and distributes electricity, and its emissions have been increasing worldwide as electric power systems expand, even as regions hit milestones like California clean energy surpluses in recent years. Smaller amounts of SF6 are used in semiconductor manufacturing and in magnesium production. 

SF6 traps 25,000 times more heat than carbon dioxide over a 100-year time scale for equal amounts of emissions, and while CO2 emissions flatlined in 2019 globally, that comparison underscores the potency of SF6. That means a relatively small amount of the gas can have a significant impact on climate warming. Because of its extremely large global warming potential and long atmospheric lifetime, SF6 emissions will influence Earth’s climate for thousands of years.

In this study, researchers from NOAA’s Global Monitoring Laboratory, as record greenhouse gas concentrations drive demand for better data, working with colleagues at EPA, CIRES, and the University of Maryland, estimated U.S. SF6 emissions for the first time from atmospheric measurements collected at a network of tall towers and aircraft in NOAA’s Global Greenhouse Gas Reference Network. The researchers provided an estimate of SF6 emissions independent from the EPA’s estimate, which is based on reported SF6 emissions for some industrial facilities and on estimated SF6 emissions for others.

“We observed differences between our atmospheric estimates and the EPA’s activity-based estimates,” said study lead author Lei Hu, a Global Monitoring Laboratory researcher who was a CIRES scientist at the time of the study. “But by closely collaborating with the EPA, we were able to identify processes potentially responsible for a significant portion of this difference, highlighting ways to improve emission inventories and suggesting additional emission mitigation opportunities, such as forthcoming EPA carbon capture rules for power plants, in the future.” 

In the 1990s, the EPA launched voluntary partnerships with the electric power, where power-sector carbon emissions are falling as generation shifts, magnesium, and semiconductor industries to reduce SF6 emissions after the United States recognized that its emissions were significant. In 2011, large SF6 -emitting facilities were required to begin tracking and reporting their emissions under the EPA Greenhouse Gas Reporting Program. 

Hu and her colleagues documented a decline of about 60 percent in U.S. SF6 emissions between 2007-2018, amid global declines in coal-fired power in some years—equivalent to a reduction of between 6 and 20 million metric tons of CO2 emissions during that time period—likely due in part to the voluntary emission reduction partnerships and the EPA reporting requirement. A more modest declining trend has also been reported in the EPA’s national inventories submitted annually under the United Nations Framework Convention on Climate Change. 

Examining the differences between the NOAA and EPA independent estimates, the researchers found that the EPA’s past inventory analyses likely underestimated SF6 emissions from electrical power transmission and distribution facilities, and from a single SF6 production plant in Illinois. According to Hu, the research collaboration has likely improved the accuracy of the EPA inventories. The 2023 draft of the EPA’s U.S. Greenhouse Gas Emissions and Sinks: 1990-2021 used the results of this study to support revisions to its estimates of SF6 emissions from electrical transmission and distribution. 

The collaboration may also lead to improvements in the atmosphere-based estimates, helping NOAA identify how to expand or rework its network to better capture emitting industries or areas with significant emissions, according to Steve Montzka, senior scientist at GML and one of the paper’s authors.

Hu and her colleagues also found a seasonal variation in SF6 emissions from the atmosphere-based analysis, with higher emissions in winter than in summer. Industry representatives identified increased servicing of electrical power equipment in the southern states and leakage from aging brittle sealing materials in the equipment in northern states during winter as likely explanations for the enhanced wintertime emissions—findings that suggest opportunities for further emissions reductions.

“This is a great example of the future of greenhouse gas emission tracking, where inventory compilers and atmospheric scientists work together to better understand emissions and shed light on ways to further reduce them,” said Montzka.

Ontario Global Adjustment Charge faces constitutional scrutiny as a regulatory charge vs tax; Court of Appeal revives case over electricity pricing, feed-in tariff contracts, IESO policy, and hydro rate impacts on consumers and industry.

Key Points

A provincial electricity fee funding generator contracts, now central to a court fight over tax versus regulatory charge.

✅ Funds gap between market price and contracted generator rates

✅ At issue: regulatory charge vs tax under constitutional law

✅ Linked to feed-in tariff, IESO policy, and hydro rate hikes

Ontario’s court of appeal has decided that a constitutional challenge of a steep provincial electricity charge should get its day in court, overturning a lower-court judgment that had dismissed the legal bid.

Hamilton, Ont.-based National Steel Car Ltd. launched the challenge in 2017, saying Ontario’s so-called global adjustment charge was unconstitutional because it is a tax — not a valid regulatory charge — that was not passed by the legislature.

The global adjustment funds the difference between the province’s hourly electricity price and the price guaranteed under contracts to power generators. It is “the component that covers the cost of building new electricity infrastructure in the province, maintaining existing resources, as well as providing conservation and demand management programs,” the province’s Independent Electricity System Operator says.

However, the global adjustment now makes up most of the commodity portion of a household electricity bill, and its costs have ballooned, as regulators elsewhere consider a proposed 14% rate hike in Nova Scotia.

Ontario’s auditor general said in 2015 that global adjustment fees had increased from $650 million in 2006 to more than $7 billion in 2014. She added that consumers would pay $133 billion in global adjustment fees from 2015 to 2032, after having already paid $37 billion from 2006 to 2014.

National Steel Car, which manufactures steel rail cars and faces high electricity rates that hurt Ontario factories, said its global adjustment costs went from $207,260 in 2008 to almost $3.4 million in 2016, according to an Ontario Court of Appeal decision released on Wednesday.

The company claimed the global adjustment was a tax because one of its components funds electricity procurement contracts under a “feed-in tariff” program, or FIT, which National Steel Car called “the main culprit behind the dramatic price increases for electricity,” the decision said.

Ontario’s auditor general said the FIT program “paid excessive prices to renewable energy generators.” The program has been ended, but contracts awarded under it remain in place.

National Steel Car claimed the FIT program “was actually designed to accomplish social goals unrelated to the generation of electricity,” such as helping rural and indigenous communities, and was therefore a tax trying to help with policy goals.

“The appellant submits that the Policy Goals can be achieved by Ontario in several ways, just not through the electricity pricing formula,” the decision said.

National Steel Car also argued the global adjustment violated a provincial law that requires the government to hold a referendum for new taxes.

“The appellant’s principal claim is that the Global Adjustment was a ‘colourable attempt to disguise a tax as a regulatory charge with the purpose of funding the costs of the Policy Goals,’” the decision said. “The appellant pressed this argument before the motion judge and before this court. The motion judge did not directly or adequately address it.”

The Ontario government applied to have the challenge thrown out for having “no reasonable cause of action,” and a Superior Court judge did so in 2018, saying the global adjustment is not a tax.

National Steel Car appealed the decision, and the decision published Wednesday allowed the appeal, set aside the lower-court judgment, and will send the case back to Superior Court, where it could get a full hearing.

“The appellant’s claim is sufficiently plausible on the evidentiary record it put forward that the applications should not have been dismissed on a pleadings motion before the development of a full record,” wrote Justice Peter D. Lauwers. “It is not plain, obvious and beyond doubt that the Global Adjustment, and particularly the challenged component, is properly characterized as a valid regulatory charge and not as an impermissible tax.”

Jerome Morse of Morse Shannon LLP, one of National Steel Car’s lawyers, said the Ontario government would now have 60 days to decide whether to seek permission to appeal to the Supreme Court of Canada.

“What the court has basically said is, ‘this is a plausible argument, here are the reasons why it’s plausible, there was no answer to this,’” Morse told the Financial Post.

Ontario and the IESO had supported the lower-court decision, but there has been a change in government since the challenge was first launched, with Progressive Conservative Premier Doug Ford replacing the Liberals and Kathleen Wynne in power. The Liberals had launched a plan aimed at addressing hydro costs before losing in a 2018 election, the main thrust of which had been to refinance global adjustment costs.

Wednesday’s decision states that “Ontario’s counsel advised the court that the current Ontario government ‘does not agree with the former government’s electricity procurement policy (since-repealed).’

“The government’s view is that: ‘The solution does not lie with the courts, but instead in the political arena with political actors,’” it adds.

A spokesperson for Ontario Energy Minister Greg Rickford said in an email that they are reviewing the decision but “as this matter is in the appeal period, it would be inappropriate to comment.” 

Ontario had also requested to stay the matter so a regulator, the Ontario Energy Board, could weigh in, while the Nova Scotia regulator approved a 14% hike in a separate case.

“However, Ontario only sought this relief from the motion judge in the alternative, and given the motion judge’s ultimate decision, she did not rule on the stay,” Thursday’s decision said. “It would be premature for this court to rule on the issue, although it seems incongruous for Ontario to argue that the Superior Court is the convenient forum in which to seek to dismiss the applications as meritless, but that it is not the convenient forum for assessing the merits of the applications.”

National Steel Car’s challenge bears a resemblance to the constitutional challenges launched by Ontario and other provinces over the federal government’s carbon tax, but Justice Lauwers wrote “that the federal legislative scheme under consideration in those cases is distinctly different from the legislation at issue in this appeal.”

“Nothing in those decisions impacts this appeal,” the judge added.

California Renewable Energy Record highlights near-100% clean power as CAISO reports solar, wind, and storage meeting demand, with Interstate 10 arrays and distributed rooftop photovoltaics boosting the grid during Stagecoach, signaling progress toward 100%.

Key Points

CA Renewable Energy Record marks CAISO's peak when renewables nearly met total load, led by utility solar and storage.

✅ CAISO hit 99.87% renewables serving load at 2:50 p.m.

✅ Two-thirds of power came from utility-scale solar along I-10.

✅ Tariff inquiry delays solar-storage projects statewide.

Renewable electricity met just shy of 100% of California's demand for the first time on Saturday, officials said, much of it from large amounts of solar power, part of a California solar boom, produced along Interstate 10, an hour east of the Coachella Valley.

While partygoers celebrated in the blazing sunshine at the Stagecoach music festival,  "at 2:50 (p.m.), we reached 99.87 % of load served by all renewables, which broke the previous record," said Anna Gonzales, spokeswoman for California Independent System Operator, a nonprofit that oversees the state's bulk electric power system and transmission lines. Solar power provided two-thirds of the amount needed.

Environmentalists who've pushed for years for all of California's power to come from renewables and meet clean energy targets were jubilant as they watched the tracker edge to 100% and slightly beyond. 

"California busts past 100% on this historic day for clean energy!" Dan Jacobson, senior adviser to Environment California, tweeted.

"Once it hit 100%, we were very excited," said Laura Deehan, executive director for Environment California. She said the organization and others have worked for 20 years to push the Golden State to complete renewable power via a series of ever tougher mandates, even as solar and wind curtailments increase across the grid. "California solar plants play a really big role."

But Gonzales said CAISO double-checked the data Monday and had to adjust it slightly because of reserves and other resource needs, an example of rising curtailments in the state. 

Environment California pushed for 1 million solar rooftops statewide, which has been achieved, adding what some say is a more environmentally friendly form of solar power, though wildfire smoke can undermine gains, than the solar farms, which eat up large swaths of the Mojave desert and fragile landscapes.

'Need to act with that same boldness':A record 10% of the world's power was generated by wind, solar methods in 2021

Deehan said in a statement that more needs to be done, especially at the federal level. "Despite incredible progress illustrated by the milestone this weekend, and the fact that U.S. renewable electricity surpassed coal in 2022, a baffling regulatory misstep by the Biden administration has advocates concerned about backsliding on California’s clean energy targets." 

Deehan said a Department of Commerce inquiry into tariffs on imported solar panels is delaying thousands of megawatts of solar-storage projects in California, even as U.S. renewable energy hit a record 28% in April across the grid.

Still, Deehan said, “California has shown that, for one brief and shining moment, we could do it! It's time to move to 100% clean energy, 100% of the time.”
