UK commitment to nuclear questioned

Ukraine Power Grid Resilience details preparations for winter blackouts, airstrike defense, decentralized generation, backup generators, battery storage, DTEK restorations, EU grid synchronization, and upgraded air defenses to safeguard electricity, heating, water, and essential services.

Key Points

Ukraine Power Grid Resilience is a strategy to harden energy systems against winter attacks and outages.

✅ DTEK repairs, backup equipment, and fortified plants across Ukraine

✅ Expanded air defenses targeting missiles and attack drones

✅ EU grid sync enables emergency imports and power trading

Oleksandr Gindyuk is determined not to be caught off guard if electricity supplies fail again this winter. When Russia pounded Ukraine’s power grid with widespread and repeated waves of airstrikes last year, causing massive rolling blackouts, his wife had just given birth to their second daughter.

“It was quite difficult,”  Gindyuk, who lives with his family in the suburbs of the capital, Kyiv, told CNN. “There is no life in our house if there is no electricity. Without electricity, we have no water, light or heating.”

He has spent the summer preparing for Russia to repeat its strategy, which was designed to sow terror and make life unsustainable, robbing Ukrainians of heat, water and health services. “We are totally ready — we have a diesel generator and a powerful 9 kWh battery. We are not scared, we are ready,” Gindyuk told CNN.

As families like Gindyuk’s gird themselves for the possibility of another dark winter, Ukraine has been rushing to rebuild and, drawing on protecting the grid lessons, protect its fragile energy infrastructure.

The summer provided a respite for Ukraine’s power grid. Russia focused its attacks on military targets and on ports on the Black Sea and the Danube River, to hinder Ukraine’s efforts to move grain and choke off an important income stream.

As the days grow shorter and the temperatures drop, Russia has another opportunity to try to break Ukrainian resilience with punishing blackouts. But this winter, defense and energy officials say Ukraine is better prepared.

With limited Ukrainian air defenses in operation last year, Russia was able to target and hit the energy grid easily, including during missile and drone assaults on Kyiv’s grid that strained responders.

“The Russians may use a combination of missile weapons and attack UAVs (unmanned aerial vehicles, or drones). These will definitely not be such primitive attacks as last year. It will be difficult for the Russians to achieve a result - we are also preparing and understanding how they act.”

DTEK, the country’s largest private energy company, has spent the past seven months restoring infrastructure, trying to boost output and bolstering defenses at its facilities across Ukraine, mindful of Russian utility hacks reported elsewhere.

“We restored what could be restored, bought back-up equipment and installed defenses around power plants, as Russian-linked breaches at US plants have underscored risks,” DTEK chief executive Maxim Timchenko told CNN.

The company generates around a quarter of Ukraine’s electricity and runs 40% of its grid network, making it a prime target for Russian attacks. Four DTEK employees have been killed while on duty and its power stations have been attacked nearly 300 times since the start of the full-scale invasion, according to the company. “Last winter, determination carried us through. This winter we are stronger, and our people are more experienced,” Timchenko said.

Russia launched 1,200 attacks on Ukraine’s energy system between October 2022 and April 2023, with every thermal power and hydro-electric plant in the country sustaining some damage, according to DTEK.

In a damage assessment report released in June, the United Nations Development Programme said that Ukraine’s power generation capacity had been reduced to about half of what it was before Russia’s full-scale invasion. “Ukraine’s power system continues to operate in an emergency mode, which affects both power grids and generation, amid rising concerns about state-backed grid hacking worldwide,” a news release accompanying the report said.

The report also laid out a roadmap to rebuilding the energy sector, prioritizing decentralization, renewable energy sources and greater integration with the European Union. Ukraine has been hooked into the EU’s power grid since the full-scale invasion, allowing it to synchronize and trade power with the bloc. But the massive wave of attacks on energy infrastructure last winter threw that balance off kilter.

California Net Zero Grid Investment will fuel electrification, renewable energy buildout, EV adoption, and grid modernization, boosting utilities, solar, and storage, while policy, IRA incentives, and transmission upgrades drive reliability and long-term rate base growth.

Key Points

Funding to electrify sectors and modernize the grid, scaling renewables, EVs, and storage to meet 2045 net zero goals.

✅ $370B over 22 years to meet 2045 net zero target

✅ Utilities lead gains via grid modernization and rate base growth

✅ EVs, solar, storage scale; IRA credits offset costs

$370 billion: That’s the investment Edison International CEO Pedro Pizarro says is needed for California’s power grid to meet the state’s “net zero” goal for CO2 emissions by 2045.

Getting there will require replacing fossil fuels with electricity in transportation, HVAC systems for buildings and industrial processes. Combined with population growth and data demand potentially augmented by artificial intelligence, that adds up to an 82 percent increase in electricity demand over 22 years, or 3 percent annually, and a potential looming shortage if buildout lags.

California’s plans also call for phasing out fossil fuel generation in the state, despite ongoing dependence on fossil power during peaks. And presumably, its last nuclear plant—PG&E Corp’s (PCG) Diablo Canyon—will be eventually be shuttered as well. So getting there also means trebling the state’s renewable energy generation and doubling usage of rooftop solar.

Assuming this investment is made, it’s relatively easy to put together a list of beneficiaries. Electric vehicles hit 20 percent market share in the state in Q2, even as pandemic-era demand shifts complicate load forecasting. And while competition from manufacturers has increased, leading manufacturers like Tesla TSLA -3% Inc (TSLA) can look forward to rising sales for some time—though that’s more than priced in for Elon Musk’s company at 65 times expected next 12 months earnings.

In the past year, California regulators have dialed back net metering through pricing changes affecting compensation, a subsidy previously paying rooftop solar owners premium prices for power sold back to the grid. That’s hit share prices of SunPower Corp (SPWR) and Sunrun Inc (RUN) quite hard, by further undermining business plans yet to demonstrate consistent profitability.

Nonetheless, these companies too can expect robust sales growth, as global prices for solar components drop and Inflation Reduction Act tax credits at least somewhat offset higher interest rates. And the combination of IRA tax credits and U.S. tariff walls will continue to boost sales at solar manufacturers like JinkoSolar Holding (JKS).

The surest, biggest beneficiaries of California’s drive to Net Zero are the utilities, reflecting broader utility trends in grid modernization, with investment increasing earnings and dividends. And as the state’s largest pure electric company, Edison has the clearest path.

Edison is currently requesting California regulators OK recovery over a 30-year period of $2.4 billion in losses related to 2017 wildfires. Assuming a amicable decision by early next year, management can then turn its attention to upgrading the grid. That investment is expected to generate long-term rate base growth of 8 percent at year, fueling 5 to 7 percent annual earnings growth through 2028 with commensurate dividend increases.

That’s a strong value proposition Edison stock, with trades at just 14 times expected next 12 months earnings. The yield of roughly 4.4 percent at current prices was increased 5.4 percent this year and is headed for a similar boost in December.

When California deregulated electricity in 1996, it required utilities with rare exceptions to divest their power generation. As a result, Edison’s growth opportunity is 100 percent upgrading its transmission and distribution grid. And its projects can typically be proposed, sited, permitted and built in less than a year, limiting risk of cost overruns to ensure regulatory approval and strong investment returns.

Edison’s investment plan is also pretty much immune to an unlikely backtracking on Net Zero goals by the state. And the company has a cost argument as well: Dr Pizarro cites U.S. Department of Energy and Department of Transportation data to project inflation-adjusted savings of 40 percent in California’s total customer energy bills from full electrification.

There’s even a reason to believe 40 percent savings will prove conservative. Mainly, gasoline currently accounts for a bit more than half energy expenditures. And after a more than 10-year global oil and gas investment drought, supplies are likely get tighter and prices possibly much higher in coming years.

Of course, those savings will only show up after significant investment is made. At this point, no major utility system in the world runs on 100 percent renewable energy, and California’s blackout politics underscore how reliability concerns shape deployment. And the magnitude of storage technology needed to overcome intermittency in solar and wind generation is not currently available let alone affordable, though both cost and efficiency are advancing.

Taking EVs from 20 to 100 percent of California’s new vehicle sales calls for a similar leap in efficiency and cost, even with generous federal and state subsidy. And while technology to fully electrify buildings and homes is there, economically retrofitting statewide is almost certainly going to be a slog.

At the end of the day, political will is likely to be as important as future technological advance for how much of Pizarro’s $370 billion actually gets spent. And the same will be true across the U.S., with state governments and regulators still by and large calling the shots for how electricity gets generated, transmitted and distributed—as well as who pays for it and how much, even as California’s exported policies influence Western markets.

Ironically, the one state where investors don’t need to worry about renewable energy’s prospects is one of the currently reddest politically. That’s Florida, where NextEra Energy NEE +2.8% (NEE) and other utilities can dramatically cut costs to customers and boost reliability by deploying solar and energy storage.

You won’t hear management asserting it can run the Sunshine State on 100 percent renewable energy, as utilities and regulators do in some of the bluer parts of the country. But by demonstrating the cost and reliability argument for solar deployment, NextEra is also making the case why its stock is America’s highest percentage bet on renewables’ growth—particularly at a time when all things energy are unfortunately becoming increasingly, intensely political.

Yukon SMR Feasibility Study examines small modular reactors as low-emissions nuclear power for Yukon's grid and remote communities, comparing costs, safety, waste, and reliability with diesel generation, renewables, and energy efficiency.

Key Points

An official assessment of small modular reactors as low-emission power options for Yukon's grid and remote sites.

✅ Compares SMR costs vs diesel, hydro, wind, and solar

✅ Evaluates safety, waste, fuel logistics, decommissioning

✅ Considers remote community loads and grid integration

The Yukon government is looking for ways to reduce the territory's emissions, and wondering if nuclear power is one way to go.

The territory is undertaking a feasibility study, and, as some developers note, combining multiple energy sources can make better projects, to determine whether there's a future for SMRs — small modular reactors — as a low-emissions alternative to things such as diesel power.

The idea, said John Streicker, Yukon's minister of energy, mines and resources, is to bring the SMRs into the Yukon to generate electricity.

"Even the micro ones, you could consider in our remote communities or wherever you've got a point load of energy demand," Streicker said. "Especially electricity demand."

For remote coastal communities elsewhere in Canada, tidal energy is being explored as a low-emissions option as well.

SMRs are nuclear reactors that use fission to produce energy, similar to existing large reactors, but with a smaller power capacity. The International Atomic Energy Agency (IAEA) defines reactors as "small" if their output is under 300 MW. A traditional nuclear power plant produces about three times as much power or more.

They're "modular" because they're designed to be factory-assembled, and then installed where needed. 

Several provinces have already signed an agreement supporting the development of SMRs, and in Alberta's energy mix that conversation spans both green and fossil power, and Canada's first grid-scale SMRs could be in place in Ontario by 2028 and Saskatchewan by 2032.

A year ago, the government of Yukon endorsed Canada's SMR action plan, at a time when analysts argue that zero-emission electricity by 2035 is practical and profitable, agreeing to "monitor the progress of SMR technologies throughout Canada with the goal of identifying potential for applicability in our northern jurisdiction."

The territory is now following through by hiring someone to look at whether SMRs could make sense as a cleaner-energy alternative in Yukon. 

The territorial government has set a goal of reducing emissions by 45 per cent by 2030, excluding mining emissions, even as some analyses argue that zero-emissions electricity by 2035 is possible, and "future emissions actions for post-2030 have not yet been identified," reads the government's request for proposals to do the SMR study. 

Streicker acknowledges the potential for nuclear power in Yukon is a bit of "long shot" — but says it's one that can't be ignored.

"We need to look at all possible solutions," he said, as countries such as New Zealand's electricity sector debate their future pathways.

"I don't want to give the sense like we're putting all of our emphasis and energy towards nuclear power. We're not."

According to Streicker, it's nothing more than a study at this point.

Don't bother, researcher says
Still, M.V. Ramana, a professor at the School of Public Policy and Global Affairs at the University of British Columbia, said it's a study that's likely a waste of time and money. He says there's been plenty of research already, and to him, SMRs are just not a realistic option for Yukon or anywhere in Canada.

"I would say that, you know, that study can be done in two weeks by a graduate student, essentially, all right? They just have to go look at the literature on SMRs and look at the critical literature on this," Ramana said.

Ramana co-authored a research paper last year, looking at the potential for SMRs in remote communities or mine sites. The conclusion was that SMRs will be too expensive and there won't be enough demand to justify investing in them.

He said nuclear reactors are expensive, which is why their construction has "dried up" in much of the world.

"They generate electricity at very high prices," he said.

'They just have to go look at the literature,' said M.V. Ramana, a professor at the School of Public Policy and Global Affairs at the University of British Columbia. (Paul Joseph)
"[For] smaller reactors, the overall costs go down. But the amount of electricity that they will generate goes down even further."

The environmental case is also shaky, according to a statement signed last year by dozens of Canadian environmental and community groups, including the Sierra Club, Greenpeace, the Council of Canadians and the Canadian Environmental Law Associaton (CELA). The statement calls SMRs a "dirty, dangerous distraction" from tackling climate change and criticized the federal government for investing in the technology.

"We have to remember that the majority of the rhetoric we hear is from nuclear advocates. And so they are promoting what I would call, and other legal scholars and academics have called, a nuclear fantasy," said Kerrie Blaise of CELA.

Blaise describes the nuclear industry as facing an unknown future, with some of North America's larger reactors set to be decommissioned in the coming years. SMRs are therefore touted as the future.

"They're looking for a solution. And so that I would say climate change presents that timely solution for them."

Blaise argues the same safety and environmental questions exist for SMRs as for any nuclear reactors — such as how to produce and transport fuel safely, what to do with waste, and how to decommission them — and those can't be glossed over in a single-minded pursuit of lower carbon emissions.  

Main focus is still renewables, minister says
Yukon's energy minister agrees, and he's eager to emphasize that the territory is not committed to anything right now beyond a study.

"Every government has a responsibility to do diligence around this," Streicker said.

He also dismisses the idea that studying nuclear power is any sort of distraction from his government's response to climate change right now. Yukon's main focus is still renewable energy such as solar and wind power, though Canada's solar progress is often criticized as lagging, increasing efficiency, and connecting Yukon's grid to the hydro project in Atlin, B.C., he said.

Streicker has been open to nuclear energy in the past. As a federal Green Party candidate in 2008, Streicker broke with the party line to suggest that nuclear could be a viable energy alternative. 

He acknowledges that nuclear power is always a hot-button issue, and Yukoners will have strong feelings about it. A lot will depend on how any future regulatory process works, he says.

"There's some people that think it's the 'Hail Mary,' and some people that think it's evil incarnate," he said. 

"Buried deep within Our Clean Future [Yukon's climate change strategy], there's a line in there that says we should keep an eye on other technologies, for example, nuclear. That's what this [study] is — it's to keep an eye on it."

Nuclear Waste Corrosion accelerates as stainless steel, glass, and ceramics interact in aqueous conditions, driving localized corrosion in repositories like Yucca Mountain, according to Nature Materials research on high-level radioactive waste storage.

Key Points

Degradation of waste forms and canisters from water-driven chemistry, causing accelerated, localized corrosion in storage.

✅ Stainless steel-glass contact triggers severe localized attack

✅ Ceramics and steel co-corrosion observed under aqueous conditions

✅ Yucca Mountain-like chemistry accelerates waste form degradation

The materials the United States and other countries plan to use to store high-level nuclear waste, even as utilities expand carbon-free electricity portfolios, will likely degrade faster than anyone previously knew because of the way those materials interact, new research shows.

The findings, published today in the journal Nature Materials (https://www.nature.com/articles/s41563-019-0579-x), show that corrosion of nuclear waste storage materials accelerates because of changes in the chemistry of the nuclear waste solution, and because of the way the materials interact with one another.

"This indicates that the current models may not be sufficient to keep this waste safely stored," said Xiaolei Guo, lead author of the study and deputy director of Ohio State's Center for Performance and Design of Nuclear Waste Forms and Containers, part of the university's College of Engineering. "And it shows that we need to develop a new model for storing nuclear waste."

Beyond waste storage, options like carbon capture technologies are being explored to reduce atmospheric CO2 alongside nuclear energy.

The team's research focused on storage materials for high-level nuclear waste -- primarily defense waste, the legacy of past nuclear arms production. The waste is highly radioactive. While some types of the waste have half-lives of about 30 years, others -- for example, plutonium -- have a half-life that can be tens of thousands of years. The half-life of a radioactive element is the time needed for half of the material to decay.

The United States currently has no disposal site for that waste; according to the U.S. General Accountability Office, it is typically stored near the nuclear power plants where it is produced. A permanent site has been proposed for Yucca Mountain in Nevada, though plans have stalled. Countries around the world have debated the best way to deal with nuclear waste; only one, Finland, has started construction on a long-term repository for high-level nuclear waste.

But the long-term plan for high-level defense waste disposal and storage around the globe is largely the same, even as the U.S. works to sustain nuclear power for decarbonization efforts. It involves mixing the nuclear waste with other materials to form glass or ceramics, and then encasing those pieces of glass or ceramics -- now radioactive -- inside metallic canisters. The canisters then would be buried deep underground in a repository to isolate it.

At the generation level, regulators are advancing EPA power plant rules on carbon capture to curb emissions while nuclear waste strategies evolve.

In this study, the researchers found that when exposed to an aqueous environment, glass and ceramics interact with stainless steel to accelerate corrosion, especially of the glass and ceramic materials holding nuclear waste.

In parallel, the electrical grid's reliance on SF6 insulating gas has raised warming concerns across Europe.

The study qualitatively measured the difference between accelerated corrosion and natural corrosion of the storage materials. Guo called it "severe."

"In the real-life scenario, the glass or ceramic waste forms would be in close contact with stainless steel canisters. Under specific conditions, the corrosion of stainless steel will go crazy," he said. "It creates a super-aggressive environment that can corrode surrounding materials."

To analyze corrosion, the research team pressed glass or ceramic "waste forms" -- the shapes into which nuclear waste is encapsulated -- against stainless steel and immersed them in solutions for up to 30 days, under conditions that simulate those under Yucca Mountain, the proposed nuclear waste repository.

Those experiments showed that when glass and stainless steel were pressed against one another, stainless steel corrosion was "severe" and "localized," according to the study. The researchers also noted cracks and enhanced corrosion on the parts of the glass that had been in contact with stainless steel.

Part of the problem lies in the Periodic Table. Stainless steel is made primarily of iron mixed with other elements, including nickel and chromium. Iron has a chemical affinity for silicon, which is a key element of glass.

The experiments also showed that when ceramics -- another potential holder for nuclear waste -- were pressed against stainless steel under conditions that mimicked those beneath Yucca Mountain, both the ceramics and stainless steel corroded in a "severe localized" way.

Other Ohio State researchers involved in this study include Gopal Viswanathan, Tianshu Li and Gerald Frankel.

This work was funded in part by the U.S. Department of Energy Office of Science.

Meanwhile, U.S. monitoring shows potent greenhouse gas declines confirming the impact of control efforts across the energy sector.

Philippines Nuclear Energy Policy aims to add nuclear power to the energy mix via executive order, meeting rising electricity demand with 24/7 baseload while balancing safety, renewables, and imported fuel dependence in the Philippines.

Key Points

A government plan to include nuclear power in the energy mix to meet demand, ensure baseload, and uphold safety.

✅ Executive order proposed by Energy Secretary Alfonso Cusi

✅ Targets 24/7 baseload, rising electricity demand

✅ Balances safety, renewables, and energy security

Phillipines Presidential spokesman Salvador Panelo said Energy Secretary Alfonso Cusi made the proposal during last Monday's Cabinet meeting in Malacaaang. "Secretary Cusi likewise sought the approval of the issuance of a proposed executive order for the inclusion of nuclear power, including next-gen nuclear options in the country's energy mix as the Philippines is expected to the rapid growth in electricity and electricity demand, in which, 24/7 power is essential and necessary," Panelo said in a statement.

Panelo said Duterte would study the energy chief's proposal, as China's nuclear development underscores regional momentum. In the 1960s until the mid 80s, the late president Ferdinand Marcos adopted a nuclear energy program and built the Bataan Nuclear Plant.

The nuclear plant was mothballed after Corazon Aquino became president in 1986. There have been calls to revive the nuclear plant, saying it would help address the Philippines' energy supply issues. Some groups, however, said such move would be expensive and would endanger the lives of people living near the facility, citing Three Mile Island as a cautionary example.

Panelo said proposals to revive the Bataan Nuclear Plant were not discussed during the Cabinet meeting, even as debates like California's renewable classification continue to shape perceptions. Indigenous energy sources natural gas, hydro, coal, oil, geothermal, wind, solar, biomassand ethanol constitute more than half or 59.6%of the Philippines' energy mix.

Imported oil make up 31.7% while imported coal, reflecting the country's coal dependency, contribute about 8.7%.

Imported ethanol make up 0.1% of the energy mix, even as interest in atomic energy rises globally.

In 2018, Duterte said safety should be the priority when deciding whether to tap nuclear energy for the country's power needs, as countries like India's nuclear restart proceed with their own safeguards.

Jersey Electricity Standby Charge proposes a grid-backup fee for commercial self-generators of renewable energy, with a review delaying implementation; potential tariff impacts include 10-15 percent price rises, cost recovery, and network reliability.

Key Points

A grid-backup fee for Jersey self-generating businesses to share network costs fairly and curb electricity price rises.

✅ Applies to commercial self-generation using renewables or not

✅ Excludes full exporters and pre-charge installations

✅ Aims to recover grid costs and avoid 10-15% price rises

Electricity prices could rise by ten to 15 per cent if a standby charge for some commercial customers is not implemented, the chief executive of Jersey Electricity has warned.

Jersey Electricity has proposed extending a monthly fee to commercial customers who generate their own power through renewable means but still wish to be connected to Jersey’s grid as a back-up, echoing Ontario energy storage efforts to shore up reliability.

The States recently unanimously backed a proposal lodged by Deputy Carolyn Labey to delay administering the levy until a review could be carried out, as seen in the UK grid's net-zero transformation debates influencing policy. The charge, was due to be implemented next month but will now not be introduced until May, or later if the review has not concluded.

But Chris Ambler, JE chief executive, warned that failing to implement the standby charge could lead to additional costs for customers.

Some of JE’s commercial customers have already been charged a standby fee after generating their own power through non-renewable means.

The charge does not apply to businesses which export all of their electricity back into the system as part of a buy-back scheme or those which install self-generation facilities before the charge is implemented.

Deputy Labey argued that the Island had done ‘absolutely nothing’ to support the use of renewable energies and instead were discouraging locally generated power by allowing JE to set a standby charge.

She added that she was pleased that the Council of Ministers had already starting reviewing the charges but the debate needed to go ahead to ensure the work continued after the May election.

During a States debate last month, she said: ‘It is increasingly concerning that we, as an island in the 21st century, are happy for our electricity to be provided to us by an unregulated, publicly listed for-profit company with a monopoly on energy.

‘I also think that introducing a charge on renewables at a time when the world is experiencing a revolution in renewable energies, including offshore vessel charging solutions, which are becoming increasingly economic, is something that needs to be investigated.

‘Jersey should be looking to diversify our electricity production and supply, to help protect us from price and currency fluctuations and to ensure that we, as an island, receive the best deal possible for Islanders.’

Mr Ambler said that any price increase would be dependent on the future take-up and use of renewable-energy technology in Jersey.

He said: ‘The cost impact would not be significant in the short term but in the long term it could be significant. I think that we are obliged to let our customers know that.

‘It is very difficult to assess but if we are not able to levy a fair charge, then, as electricity shortages in Canada have shown, we could see prices rise by ten to 15 per cent over time.’

Mr Ambler added that his company was in favour of the use of renewable energy, with a third of the company’s electricity being generated by hydroelectric sources, but that the costs of implementing it needed to be fairly distributed, given how big battery rule changes can affect project viability elsewhere in the market.

And he said that, while it was difficult to quantify how much could be lost if the standby charge was not implemented, it could cost the company over £10 million.

‘In 2014, we only increased our prices by one per cent,’ he said. ‘We are reviewing our prices at the moment but if we did put an increase in place it would be modest and it would not be linked to the standby charge.’
