Radioactive waste plan proposed for Ontario

Cal ISO Flex Alert urges Southern California energy conservation as a Stage 2 emergency strains the power grid, with potential rolling blackouts during peak hours from 3 to 10 p.m., if demand exceeds supply.

Key Points

A statewide call to conserve power during high demand, issued by the grid operator to prevent rolling blackouts.

✅ Stage 2 emergency signals severe grid strain

✅ Peak Flex Alert hours: 3 to 10 p.m. statewide

✅ Set thermostats to 78 and avoid major appliances

Residents and businesses across Southern California were urged to conserve power Tuesday afternoon amid ongoing electricity inequities across the state as the manager of the state’s power grid warned rolling blackouts could be imminent for some power customers.

The California Independent System Operator (Cal ISO), which manages the state power grid, declared a Stage 2 emergency as of 2:30 p.m., indicating severe strain on the electrical system, similar to a recent grid alert in Alberta that relied on reserves.

Rolling blackouts for some customers could occur in a Stage 3 emergency, distinct from the intentional shut-offs some utilities use to reduce wildfire risk.

Cal ISO issued a statewide Flex Alert in effect from 3 to 10 p.m. Tuesday and Wednesday, with conservation considered especially critical during those hours, a concern heightened by pandemic-era grid operations this year.

Officials told reporters rolling blackouts might be avoided Tuesday evening if residents repeat the level of conservation seen Monday.
“If we can get the same sort of response we got yesterday, we can minimize this, or perhaps avoid it altogether,” Cal-ISO President/CEO Steve Berberich said, noting that some operators have even planned staff lockdowns during COVID-19 to maintain reliability.

Cal-ISO controls roughly 80% of the state’s power grid through Southern California Edison, Pacific Gas and Electric Co., with the utility recently restoring power after shut-offs in affected communities, and San Diego Gas & Electric.

Residents are urged to set thermostats at 78 in the afternoon and evening hours and avoiding the use of air conditioning and major appliances during the Flex Alert hours, as utilities like PG&E prepare for winter storms to improve resilience.

Advanced Nuclear Technology drives decarbonization through innovation, SMRs, and a stable grid, bolstering U.S. leadership, energy security, and clean power exports under supportive regulation and policy to meet climate goals cost-effectively.

Key Points

Advanced nuclear technology uses SMRs to deliver low-carbon, reliable power and strengthen energy security.

✅ Accelerates decarbonization with firm, low-carbon baseload power

✅ Enhances grid reliability via SMRs and advanced fuel cycles

✅ Supports U.S. leadership through exports, R&D, and modern regulation

The most cost-effective way--indeed the only reasonable way-- to reduce greenhouse gas emissions and foster our national economic and security interests is through innovation, especially next-gen nuclear power innovation. That's from Rep. Greg Walden, R-Oregon, ranking Republican member of the House Energy and Commerce Committee, speaking to a Subcommittee on Energy hearing titled, "Building a 100 Percent Clean Economy: Advanced Nuclear Technology's Role in a Decarbonized Future."

Here are the balance of his remarks.

Encouraging the deployment of atomic energy technology, strengthening our nuclear industrial base, implementing policies that helps reassert U.S. nuclear leadership globally... all provide a promising path to meet both our environmental and energy security priorities. In fact, it's the only way to meet these priorities.

So today can help us focus on what is possible and what is necessary to build on recent policies we've enacted to ensure we have the right regulatory landscape, the right policies to strengthen our domestic civil industry, and the advanced nuclear reactors on the horizon.

U.S. global leadership here is sorely needed. Exporting clean power and clean power technologies will do more to drive down global Co2 emissions on the path to net-zero emissions worldwide than arbitrary caps that countries fail to meet.

In May last year, the International Energy Agency released an informative report on the role of nuclear power in clean energy systems; it did not find current trends encouraging.

The report noted that nuclear and hydropower "form the backbone of low-carbon electricity generation," responsible for three-quarters of global low-carbon generation and the reduction of over 60 gigatons of carbon dioxide emissions over the past 50 years.

Yet IEA found in advanced economies, nuclear power is in decline, with closing plants and little new investment, "just when the world requires more low-carbon electricity."

There are various reasons for this, some relating to cost overruns and delays, others to policies that fail to value the "low-carbon and energy security attributes" of nuclear. In any case, the report found this failure to encourage nuclear will undermine global efforts to develop cleaner electricity systems.

Germany demonstrates the problem. As it chose to shut down its nuclear industry, it has doubled down on expanding renewables like solar and wind. Ironically, to make this work, it also doubled down on coal. This nuclear phase out has cost Germany $12 billion a year, 70% of which is from increased mortality risk from stronger air pollutants (this according to the National Bureau of Economic Research). If other less technologically advanced nations even could match the rate of renewables growth reached by Germany, they would only hit about a fifth of what is necessary to reach climate goals--and with more expensive energy. So, would they then be forced to bring online even more coal-fired sources than Germany?

On the other hand, as outlined by the authors of the pro-nuclear book "A Bright Future," France and Sweden have both demonstrated in the 1970s and 1980s, how to do it. They showed that the build out of nuclear can be done at five times the rate of Germany's experience with renewables, with increased electricity production and relatively lower prices.

I think the answer is obvious about the importance of nuclear. The question will be "can the United States take the lead going forward?"

We can help to do this in Congress if we fully acknowledge what U.S. leadership on nuclear will mean--both for cleaner power and industrial systems beyond electricity, here and abroad--and for the ever-important national security attributes of a strong U.S. industry.

Witnesses have noted in recent hearings that recognizing how U.S. energy and climate policy effects energy and energy technology relationships world-wide is critical to addressing emissions where they are growing the fastest and for strengthening our national security relationships.

Resurrecting technological leadership in nuclear technology around the world will meet our broader national and energy security reasons--much as unleashing U.S. LNG from our shale revolution restored our ability to counter Russia in energy markets, while also driving cleaner technology. Our nuclear energy exports boost our national security priorities.

We on Energy and Commerce have been working, in a bipartisan manner over the past few Congresses to enhance U.S. nuclear policies. There is most certainly more to do. And I think today's hearing will help us explore what can be done, both administratively and legislatively, to pave the way for advanced nuclear energy.

Let me welcome the panel today. Which, I'm pleased to see, represents several important perspectives, including industry, regulatory, safety, and international expertise, to two innovative companies--Terrapower and my home state of Oregon's NuScale. All of these witnesses can speak to what we need to do to build, operate and lead with these new technologies.

We should work to get our nation's nuclear policy in order, learning from global frameworks like the green industrial revolution abroad. Today represents a good step in that effort.

Ontario Nuclear Power Costs highlight LCOE, capex, refurbishment outlays, and waste management, compared with renewables, grid reliability, and emissions targets, informing Australia and Peter Dutton on feasibility, timelines, and electricity prices.

Key Points

They include high capex and LCOE from refurbishments and waste, offset by reliable, low-emission baseload.

✅ Refurbishment and maintenance drive lifecycle and LCOE variability.

✅ High capex and long timelines affect consumer electricity prices.

✅ Low emissions, but waste and safety compliance add costs.

Australian opposition leader Peter Dutton recently lauded Canada’s use of nuclear power as a model for Australia’s energy future. His praise comes as part of a broader push to incorporate nuclear energy into Australia’s energy strategy, which he argues could help address the country's energy needs and climate goals. However, the question arises: Is Ontario’s experience with nuclear power as cost-effective as Dutton suggests?

Dutton’s endorsement of Canada’s nuclear power strategy highlights a belief that nuclear energy could provide a stable, low-emission alternative to fossil fuels. He has pointed to Ontario’s substantial reliance on nuclear power, and the province’s exploration of new large-scale nuclear projects, as an example of how such an energy mix might benefit Australia. The province’s energy grid, which integrates a significant amount of nuclear power, is often cited as evidence that nuclear energy can be a viable component of a diversified energy portfolio.

The appeal of nuclear power lies in its ability to generate large amounts of electricity with minimal greenhouse gas emissions. This characteristic aligns with Australia’s climate goals, which emphasize reducing carbon emissions to combat climate change. Dutton’s advocacy for nuclear energy is based on the premise that it can offer a reliable and low-emission option compared to the fluctuating availability of renewable sources like wind and solar.

However, while Dutton’s enthusiasm for the Canadian model reflects its perceived successes, including recent concerns about Ontario’s grid getting dirtier amid supply changes, a closer look at Ontario’s nuclear energy costs raises questions about the financial feasibility of adopting a similar strategy in Australia. Despite the benefits of low emissions, the economic aspects of nuclear power remain complex and multifaceted.

In Ontario, the cost of nuclear power has been a topic of considerable debate. While the province benefits from a stable supply of electricity due to its nuclear plants, studies warn of a growing electricity supply gap in coming years. Ontario’s experience reveals that nuclear power involves significant capital expenditures, including the costs of building reactors, maintaining infrastructure, and ensuring safety standards. These expenses can be substantial and often translate into higher electricity prices for consumers.

The cost of maintaining existing nuclear reactors in Ontario has been a particular concern. Many of these reactors are aging and require costly upgrades and maintenance to continue operating safely and efficiently. These expenses can add to the overall cost of nuclear power, impacting the affordability of electricity for consumers.

Moreover, the development of new nuclear projects, as seen with Bruce C project exploration in Ontario, involves lengthy and expensive construction processes. Building new reactors can take over a decade and requires significant investment. The high initial costs associated with these projects can be a barrier to their economic viability, especially when compared to the rapidly decreasing costs of renewable energy technologies.

In contrast, the cost of renewable energy has been falling steadily, even as debates over nuclear power’s trajectory in Europe continue, making it a more attractive option for many jurisdictions. Solar and wind power, while variable and dependent on weather conditions, have seen dramatic reductions in installation and operational costs. These lower costs can make renewables more competitive compared to nuclear energy, particularly when considering the long-term financial implications.

Dutton’s praise for Ontario’s nuclear power model also overlooks some of the environmental and logistical challenges associated with nuclear energy. While nuclear power generates low emissions during operation, it produces radioactive waste that requires long-term storage solutions. The management of nuclear waste poses significant environmental and safety concerns, as well as additional costs for safe storage and disposal.

Additionally, the potential risks associated with nuclear power, including the possibility of accidents, contribute to the complexity of its adoption. The safety and environmental regulations surrounding nuclear energy are stringent and require continuous oversight, adding to the overall cost of maintaining nuclear facilities.

As Australia contemplates integrating nuclear power into its energy mix, it is crucial to weigh these financial and environmental considerations. While the Canadian model provides valuable insights, the unique context of Australia’s energy landscape, including its existing infrastructure, energy needs, and the costs of scrapping coal-fired electricity in comparable jurisdictions, must be taken into account.

In summary, while Peter Dutton’s endorsement of Canada’s nuclear power model reflects a belief in its potential benefits for Australia’s energy strategy, the cost-effectiveness of Ontario’s nuclear power experience is more nuanced than it may appear. The high capital and maintenance costs associated with nuclear energy, combined with the challenges of managing radioactive waste and ensuring safety, present significant considerations. As Australia evaluates its energy future, a comprehensive analysis of both the benefits and drawbacks of nuclear power will be essential to making informed decisions about its role in the country’s energy strategy.

California Rooftop Solar Cost Shift examines PG&E rate hikes, net metering changes, and utility infrastructure spending impacts on low-income households, distributed generation, and clean energy adoption, potentially raising bills and undermining grid resilience.

Key Points

A claim that rooftop solar shifts fixed grid costs to others; critics cite PG&E rates, avoided costs, and impacts.

✅ PG&E rates outpace national average, underscoring cost drivers.

✅ Net metering cuts risk burdening low- and middle-income homes.

✅ Distributed generation avoids infrastructure spend and grid strain.

California is grappling with soaring electricity prices across the state, with Pacific Gas & Electric (PG&E) rates more than double the national average and increasing at an average of 12.5% annually over the past six years. In response, Governor Gavin Newsom issued an executive order directing state energy agencies to identify ways to reduce power costs. However, recent policy shifts targeting rooftop solar users may exacerbate the problem rather than alleviate it.

The "Cost Shift" Theory

A central justification for these pricing changes is the "cost shift" theory. This theory posits that homeowners with rooftop solar panels reduce their electricity consumption from the grid, thereby shifting the fixed costs of maintaining and operating the electrical grid onto non-solar customers. Proponents argue that this leads to higher rates for those without solar installations.

However, this theory is based on a flawed assumption: that PG&E owns 100% of the electricity generated by its customers and is entitled to full profits even for energy it does not deliver. In reality, rooftop solar users supply only about half of their energy needs and still pay for the rest. Moreover, their investments in solar infrastructure reduce grid strain and save ratepayers billions by avoiding costly infrastructure projects and reducing energy demand growth, aligning with efforts to revamp electricity rates to clean the grid as well.

Impact on Low- and Middle-Income Households

The majority of rooftop solar users are low- and middle-income households. These individuals often invest in solar panels to lower their energy bills and reduce their carbon footprint. Policy changes that undermine the financial viability of rooftop solar disproportionately affect these communities, and efforts to overturn income-based charges add uncertainty about affordability and access.

For instance, Assembly Bill 942 proposes to retroactively alter contracts for millions of solar consumers, cutting the compensation they receive from providing energy to the grid, raising questions about major changes to your electric bill that could follow if their home is sold or transferred. This would force those with solar leases—predominantly lower-income individuals—to buy out their contracts when selling their homes, potentially incurring significant financial burdens.

The Real Drivers of Rising Energy Costs

While rooftop solar users are being blamed for rising electricity rates, calls for action have mounted as the true culprits lie elsewhere. Unchecked utility infrastructure spending has been a significant factor in escalating costs. For example, PG&E's rates have increased rapidly, yet the utility's spending on infrastructure projects has often been criticized for inefficiency and lack of accountability. Instead of targeting solar users, policymakers should scrutinize utility profit motives and infrastructure investments to identify areas where costs can be reduced without sacrificing service quality.

California's approach to addressing rising electricity costs by targeting rooftop solar users is misguided. The "cost shift" theory is based on flawed assumptions and overlooks the substantial benefits that rooftop solar provides to the grid and ratepayers. To achieve a sustainable and equitable energy future, the state must focus on controlling utility spending, promoting clean energy access for all, especially as it exports its energy policies across the West, and ensuring that policies support—not undermine—the adoption of renewable energy technologies.

Ukraine-ENTSO-E Grid Synchronization links Ukraine and Moldova to the European grid via secure interconnection, matching frequency for stability, resilience, and energy security, enabling cross-border support, islanding recovery, and coordinated load balancing during wartime disruptions.

Key Points

Rapid alignment of Ukraine and Moldova into the European grid to enable secure interconnection and system stability.

✅ Matches 50 Hz frequency across interconnected systems

✅ Enables cross-border support and electricity trading

✅ Improves resilience, stability, and energy security

On February 24 Ukraine’s electric grid operator disconnected the country’s power system from the larger Russian-operated network to which it had always been linked. The long-planned disconnection was meant to be a 72-hour trial proving that Ukraine could operate on its own and to protect electricity supply before winter as contingencies were tested. The test was a requirement for eventually linking with the European grid, which Ukraine had been working toward since 2017. But four hours after the exercise started, Russia invaded.

Ukraine’s connection to Europe—which was not supposed to occur until 2023—became urgent, and engineers aimed to safely achieve it in just a matter of weeks. On March 16 they reached the key milestone of synchronizing the two systems. It was “a year’s work in two weeks,” according to a statement by Kadri Simson, the European Union commissioner for energy. That is unusual in this field. “For [power grid operators] to move this quickly and with such agility is unprecedented,” says Paul Deane, an energy policy researcher at the University College Cork in Ireland. “No power system has ever synchronized this quickly before.”

Ukraine initiated the process of joining Europe’s grid in 2005 and began working toward that goal in earnest in 2017, as did Moldova. It was part of an ongoing effort to align with Europe, as seen in the Baltic states’ disconnection from the Russian grid, and decrease reliance on Russia, which had repeatedly threatened Ukraine’s sovereignty. “Ukraine simply wanted to decouple from Russian dominance in every sense of the word, and the grid is part of that,” says Suriya Jayanti, an Eastern European policy expert and former U.S. diplomat who served as energy chief at the U.S. embassy in Kyiv from 2018 to 2020.

After the late February trial period, Ukrenergo, the Ukrainian grid operator, had intended to temporarily rejoin the system that powers Russia and Belarus. But the Russian invasion made that untenable. “That left Ukraine in isolation mode, which would be incredibly dangerous from a power supply perspective,” Jayanti says. “It means that there’s nowhere for Ukraine to import electricity from. It’s an orphan.” That was a particularly precarious situation given Russian attacks on key energy infrastructure such as the Zaporizhzhia nuclear power plant and ongoing strikes on Ukraine’s power grid that posed continuing risks. (According to Jayanti, Ukraine’s grid was ultimately able to run alone for as long as it did because power demand dropped by about a third as Ukrainians fled the country.)

Three days after the invasion, Ukrenergo sent a letter to the European Network of Transmission System Operators for Electricity (ENTSO-E) requesting authorization to connect to the European grid early. Moldelectrica, the Moldovan operator, made the same request the following day. While European operators wanted to support Ukraine, they had to protect their own grids, amid renewed focus on protecting the U.S. power grid from Russian hacking, so the emergency connection process had to be done carefully. “Utilities and system operators are notoriously risk-averse because the job is to keep the lights on, to keep everyone safe,” says Laura Mehigan, an energy researcher at University College Cork.

An electric grid is a network of power-generating sources and transmission infrastructure that produces electricity and carries it from places such as power plants, wind farms and solar arrays to houses, hospitals and public transit systems. “You can’t just experiment with a power system and hope that it works,” Deane says. Getting power where it is it needed when it is needed is an intricate process, and there is little room for error, as incidents involving Russian hackers targeting U.S. utilities have highlighted for operators worldwide.

Crucial to this mission is grid interconnection. Linked systems can share electricity across vast areas, often using HVDC technology, so that a surplus of energy generated in one location can meet demand in another. “More interconnection means we can move power around more quickly, more efficiently, more cost effectively and take advantage of low-carbon or zero-carbon power sources,” says James Glynn, a senior research scholar at the Center on Global Energy Policy at Columbia University. But connecting these massive networks with many moving parts is no small order.

One of the primary challenges of interconnecting grids is synchronizing them, which is what Ukrenergo, Moldelectrica and ENTSO-E accomplished last week. Synchronization is essential for sharing electricity. The task involves aligning the frequencies of every energy-generation facility in the connecting systems. Frequency is like the heartbeat of the electric grid. Across Europe, energy-generating turbines spin 50 times per second in near-perfect unison, and when disputes disrupt that balance, slow clocks across Europe can result, reminding operators of the stakes. For Ukraine and Moldova to join in, their systems had to be adjusted to match that rhythm. “We can’t stop the power system for an hour and then try to synchronize,” Deane says. “This has to be done while the system is operating.” It is like jumping onto a moving train or a spinning ride at the playground: the train or ride is not stopping, so you had better time the jump perfectly.

U.S. Energy Transition Delays stem from grid bottlenecks, permitting red tape, solar tariff uncertainty, supply-chain shocks, and scarce affordable EVs, risking deeper fossil fuel lock-in despite climate targets for renewables, transmission expansion, and decarbonization.

Key Points

Delays driven by grid limits, permitting, and supply shocks that slow renewables, transmission, EVs, and decarbonization.

✅ Grid interconnection and transmission backlogs stall renewables

✅ Tariff probes and supply chains disrupt utility-scale solar

✅ Permitting, policy gaps, and EV costs sustain fossil fuel use

Big solar projects are facing major delays. Plans to adapt the grid to clean energy are confronting mountains of red tape. Affordable electric vehicles are in short supply.

The United States is struggling to squeeze opportunity out of an energy crisis that should have been a catalyst for cleaner, domestically produced power. After decades of putting the climate on the back burner, the country is finding itself unprepared to seize the moment and at risk of emerging from the crisis even more reliant on fossil fuels.

10 steps you can take to lower your carbon footprint
The problem is not entirely unique to the United States. Across the globe, climate leaders are warning that energy shortages including coal and nuclear disruptions prompted by Russia’s unprovoked invasion of Ukraine and high gas prices driven by inflation threaten to make the energy transition an afterthought — potentially thwarting efforts to keep global temperature rise under 1.5 degrees Celsius.

“The energy crisis exacerbated by the war in Ukraine has seen a perilous doubling down on fossil fuels by the major economies,” U.N. Secretary General António Guterres said at a conference in Vienna on Tuesday, according to prepared remarks. He warned governments and investors that a failure to immediately and more aggressively embrace clean energy could be disastrous for the planet.

U.S. climate envoy John F. Kerry suggested that nations are falling prey to a flawed logic that fossil fuels will help them weather this period of instability, undermining U.S. national security and climate goals, which has seen gas prices climb to a record-high national average of $5 per gallon. “You have this new revisionism suggesting that we have to be pumping oil like crazy, and we have to be moving into long-term [fossil fuel] infrastructure building,” he said at the Time100 Summit in New York this month. “We have to push back.”

In the United States — the world’s second-largest emitter of greenhouse gases after China — the hurdles go beyond the supply-chain crisis and sanctions linked to the war in Ukraine. The country’s lofty goals for all carbon pollution to be gone from the electricity sector by 2035 and for half the cars sold to be electric by 2030 are jeopardized by years of neglect of the electrical grid, regulatory hurdles that have set projects back years, and failures by Congress and policymakers to plan ahead.
The challenges are further compounded by plans to build costly new infrastructure for drilling and exporting natural gas that will make it even harder to transition away from the fossil fuel.

“We are running into structural challenges preventing consumers and businesses from going cleaner, even at this time of high oil and gas prices,” said Paul Bledsoe, a climate adviser in the Clinton administration who now works on strategy at the Progressive Policy Institute, a center-left think tank. “It is a little alarming that even now, Congress is barely talking about clean energy.”

Consumers are eager for more wind and solar. Companies looking to go carbon-neutral are facing growing waitlists for access to green energy, and a Pew Research Center poll in late January found that two-thirds of Americans want the United States to prioritize alternative energy over fossil fuel production.

But lawmakers have balked for more than a decade at making most of the fundamental economic and policy changes such as a clean electricity standard that experts widely agree are crucial to an orderly and accelerated energy transition. The United States does not have a tax on carbon, nor a national cap-and-trade program that would reorient markets toward lowering emissions. The unraveling in Congress of President Biden’s $1.75 trillion Build Back Better plan has added to the head winds that green-energy developers face, even as climate law results remain mixed.

“There is literally nothing pushing this forward in the U.S. beyond the tax code and some state laws,” said Heather Zichal, a former White House climate adviser who is now the chief executive of the American Clean Power Association.

The effects of the U.S. government’s halting approach are being felt by solar-panel installers, who saw the number of projects in the most recent quarter fall to the lowest level since the pandemic began. There was 24 percent less solar installed in the first quarter of 2022 than in the same quarter of 2021.

The holdup largely stems from a Commerce Department investigation into alleged tariff-dodging by Chinese manufacturers. Faced with the potential for steep retroactive penalties, hundreds of industrial-scale solar projects were frozen in early April. Weak federal policies to encourage investment in solar manufacturing left American companies ill-equipped to fill the void.

“We shut down multiple projects and had to lay off dozens of people,” said George Hershman, chief executive of SOLV Energy, which specializes in large solar installations. SOLV, like dozens of other solar companies, is now scrambling to reassemble those projects after the administration announced a pause of the tariffs.

Meanwhile, adding clean electricity to the aging power grid has become an increasingly complicated undertaking, given the failure to plan for adequate transmission lines and long delays connecting viable wind and solar projects to the electricity network.
