The summer's heat came a little early this year for large parts of the U.S. stretching from the southwest to the northeast, causing demand and prices for electricity prices to pop higher.

Typically temperatures tend to peak in July and August, but this week they have already hit record levels for this time of the year in places like Houston, Minneapolis and Philadelphia.

"It's certainly an extreme weather pattern," said Accuweather.com meteorologist Dave Houk. "From Texas, Oklahoma, Kansas up to Arkansas, the big heat has been the most persistent and it comes in waves across the northern.

Ontario government wants new gas plants to boost electricity production

Ontario Gas Plant Expansion aims to boost grid reliability as nuclear refurbishments proceed, using natural gas to meet electricity demand, despite critics urging renewables, energy storage, and efficiency to reduce carbon emissions, protecting investment growth.

 

Key Points

Ontario plan to expand gas plants for reliability during nuclear outages, sparking debate on emissions and clean options.

✅ IESO data: gas share rose from 4% (2017) to 10.4% (2022).

✅ Government cites nuclear refurbishments and demand growth.

✅ Critics propose storage, wind, solar, and efficiency.

 

The Ontario government is preparing to expand gas-fired power plants in Ontario; a move critics say will make the province's electricity system dirtier and could eventually leave taxpayers on the hook.

The province is currently soliciting bids for additional gas-fired electricity generation, which means new gas plants get built, or existing gas plants get expanded. 

It's poised to be Ontario's biggest increase in the gas-fired power supply in more than a decade since the previous Liberal government scrapped two gas plants, in Mississauga and Oakville, at a cost the auditor general pegged at around $1 billion. 

Doug Ford's energy minister, Todd Smith, says Ontario needs gas plants now to help meet an expected surge in demand for electricity as the province faces a supply shortfall in the coming years and to provide power while some units of the province's nuclear stations are down for refurbishment. 

"It's really important to have natural gas as an insurance policy to keep the lights on and provide the reliability that we need," Smith said in an interview. 

"We need natural gas for the short term, especially to get us through these refurbishments."

The portion of Ontario's electricity supply that comes from natural gas matters for the environment and the province's economy. Manufacturing companies increasingly seek clean power that emits as little carbon dioxide as possible. 

The portion of Ontario's electricity supply that comes from natural gas matters for the environment and the province's economy. Manufacturing companies increasingly seek a power supply that emits as little carbon dioxide as possible. 

Increasing the amount of gas-fired generation in the electricity system puts Ontario's ability to attract such investments at risk as it complicates balancing demand and emissions across the grid, says Evan Pivnick, program manager with Clean Energy Canada, a think tank. 

"Building new natural gas (power plants) in Ontario today should be seen as an absolute last resort for meeting our energy needs," said Pivnick in an interview. 

Ontario's electricity system has among the lowest rates of CO2 emissions in North America, with roughly half of the annual supply provided by nuclear power, one-quarter from hydro dams, and one-tenth from wind turbines. 

However, Ontario's gas plants have produced a growing amount of electricity in recent years, despite an early report exploring a gas halt by the minister, and that trend will continue if new gas plants are built. 

In 2017, gas- and oil-fired generation provided just four percent of Ontario's electricity supply, according to figures from the provincial agency that manages the grid, the Independent Electricity System Operator (IESO). 

By 2022, that figure reached 10.4 percent. 

Ontario doesn't need new gas plants to meet the electricity demand, says Bryan Purcell, vice president of policy and programs at The Atmospheric Fund. This agency invests in low-carbon projects in the Greater Toronto and Hamilton Area. 

"We're quite concerned about where Ontario's electric grid is going," said Purcell. "Thankfully, there's still time to adjust course and look at other options." 

According to Purcell and Pivnick, those options to avoid gas could include power storage (in which excess generated energy is stored for later use when electricity demand rises), wind and solar projects, or energy efficiency and conservation programs.

Heathrow Airport Power Outage: Vulnerabilities Flagged Days Before Disruption

Heathrow Airport Power Outage 2025 disrupted operations with mass flight cancellations and diversions after a grid failure, exposing infrastructure resilience gaps, crisis management flaws, and raising passenger compensation and safety oversight concerns.

 

Key Points

A grid failure closed Heathrow, causing mass cancellations and diversions, exposing resilience and communication lapses.

✅ Grid fire triggered airport-wide shutdown

✅ 1,400+ flights canceled or diverted

✅ Inquiry probes resilience, communication, compensation

 

On March 21, 2025, Heathrow Airport, Europe's busiest, suffered a catastrophic power outage, similar to another high-profile outage seen at major events, that led to the cancellation and diversion of over 1,400 flights, affecting nearly 300,000 passengers and costing airlines an estimated £100 million. The power failure, triggered by a fire at an electricity substation in west London, left Heathrow with a significant operational crisis. This disruption is even more significant considering that Heathrow is one of the most expensive airports globally, which raises concerns about its infrastructure resilience and broader electricity system resilience across Europe.

In a parliamentary committee meeting, Heathrow officials admitted that vulnerabilities in the airport’s power supply were flagged just days before the outage. Nigel Wicking, Chief Executive of the Heathrow Airline Operators' Committee (HAOC), informed MPs that concerns regarding power resilience had been raised on March 15, following disruptions caused by cable thefts impacting runway lights. Despite these warnings, the airport’s management did not address the vulnerabilities urgently, even as UK net zero policies continue to reshape infrastructure planning, which ultimately led to the disastrous outage.

The airport was closed for a day, with serious consequences for not only airlines but also the surrounding community and businesses. British Airways alone faced millions of pounds in losses, and passengers experienced significant emotional distress, missing vital life events like weddings and funerals due to flight cancellations. The committee is now questioning officials from National Grid and Scottish and Southern Electricity Networks to better understand why Heathrow’s infrastructure failed, in the context of a cleaner grid following the British carbon tax that reduced coal use, how it communicated with affected parties, and what measures will be taken to compensate impacted passengers.

Heathrow’s Chief Executive, Thomas Woldbye, defended the closure decision, stating it would have been disastrous to keep the airport open under such circumstances. He noted that continuing operations would have left tens of thousands of passengers stranded and would have posed safety risks due to the failure of fire surveillance and CCTV systems. However, Wicking, representing the airlines, pointed out that Heathrow’s lack of resilience was unacceptable given the amount spent on the airport, emphasizing the need for better infrastructure, including addressing SF6 in switchgear during upgrades, and more transparent management practices.

Looking forward, the MPs intend to investigate the airport’s emergency preparedness, why the resilience review from 2018 wasn’t shared with airlines, and whether enough preventative measures were in place amid surging data demand that could strain electricity supplies. The outcome of this inquiry could have lasting effects on how Heathrow and other major airports handle their infrastructure and crisis management systems, as drought-driven hydro challenges demonstrate the wider climate stresses on power networks.

US NRC streamlines licensing for advanced reactors

NRC Advanced Reactor Licensing streamlines a risk-informed, performance-based, technology-inclusive pathway for advanced non-light water reactors, aligning with NEIMA to enable predictable regulatory reviews, inherent safety, clean energy deployment, and industrial heat, hydrogen, and desalination applications.

 

Key Points

A risk-informed, performance-based NRC pathway streamlining licensing for advanced non-light water reactors.

✅ Aligned with NEIMA: risk-informed, performance-based, tech-inclusive

✅ Predictable licensing for advanced non-light water reactor designs

✅ Enables clean heat, hydrogen, desalination beyond electricity

 

The US Nuclear Regulatory Commission (NRC) voted 4-0 to approve the implementation of a more streamlined and predictable licensing pathway for advanced non-light water reactors, aligning with nuclear innovation priorities identified by industry advocates, the Nuclear Energy Institute (NEI) announced, and amid regional reliability measures such as New England emergency fuel stock plans that have drawn cost scrutiny.

This approach is consistent with the Nuclear Energy Innovation and Modernisation Act (NEIMA), a nuclear innovation act passed in 2019 by the US Congress calling for the development of a risk-informed, performance-based and technology inclusive licensing process for advanced reactor developers.

NEI Chief Nuclear Officer Doug True said: “A modernised regulatory framework is a key enabler of next-generation nuclear technologies that, amid ACORE’s challenge to DOE subsidy proposals in energy market proceedings, can help us meet our energy needs while protecting the climate. The Commission’s unanimous approval of a risk-informed and performance-based licensing framework paves the way for regulatory reviews to be aligned with the inherent safety characteristics, smaller reactor cores and simplified designs of advanced reactors.”

Over the last several years the industry’s Licensing Modernisation Project, sponsored by US Department of Energy, led by Southern Nuclear, and supported by NEI’s Advanced Reactor Regulatory Task Force, and influenced by a presidential order to bolster uranium and nuclear energy, developed the guidance for this new framework. Amid shifts in the fuel supply chain, including the U.S. ban on Russian uranium, this approach will inform the development of a new rule for licensing advanced reactors, which NEIMA requires.

“A well-defined licensing path will benefit the next generation of nuclear plants, especially as regions consider New England market overhaul efforts, which could meet a wide range of applications beyond generating electricity such as producing heat for industry, desalinating water, and making hydrogen – all without carbon emissions,” True noted.

UK price cap on household energy bills expected to cost 89bn

UK Energy Price Guarantee Cost forecasts from Cornwall Insight suggest an £89bn bill, tied to wholesale gas prices, OBR projections, and fiscal policy, to shield households amid the cost of living crisis.

 

Key Points

It is the projected government spend to cap household bills, driven by wholesale gas prices and OBR market forecasts.

✅ Base case: £89bn over two years, per Cornwall Insight

✅ Range: £72bn to £140bn, volatile wholesale gas costs

✅ Excludes 6-month business support estimated at £22bn-£48bn

 

Liz Truss’s intervention to freeze energy prices for households for two years is expected to cost the government £89bn, according to the first major costing of the policy by the sector’s leading consultancy.

The analysis from Cornwall Insight, seen exclusively by the Guardian, shows the prime minister’s plan to tackle the cost of living crisis could cost as much as £140bn in a worst-case scenario.

Truss announced in early September that the average annual bill for a typical household would be capped at £2,500 to protect consumers from the intensifying cost of living crisis amid high winter energy costs and a scheduled 80% rise in the cap to £3,549.

The ultimate cost of the policy is uncertain as it is highly dependent on the wholesale cost of gas, including UK natural gas prices which have soared since Russia’s invasion of Ukraine put a squeeze on already-volatile international markets. Ballpark projections had put the cost anywhere from £100bn to £150bn.

The Office for Budget Responsibility is expected to give its forecast for the bill when it provides its independent assessment of Kwasi Kwarteng’s medium-term fiscal plan, which the chancellor said on Tuesday would still happen on 23 November despite previous reports that it would be brought forward.

Cornwall Insight analysed projections of wholesale market moves to cost the intervention. In its base case scenario, analysts expect the policy to cost £89bn. That assumes the cost of supporting each household would be just over £1,000 in the first year, and about £2,000 in the second year.

The study’s authors said the wholesale price of gas would be influenced by energy demand, the severity of weather, “geo-political uncertainty” and prices for liquified natural gas as Europe seeks to refill storage facilities, which countries have rushed to fill up this winter but which could be relatively empty by next spring.

In the best-case outcome, the policy would cost £72bn, with some projections pointing to a 16% decrease in energy bills in April for households, while the “extreme high” outlook would see the government shell out £140bn to protect 29m UK households.

Gas prices are expected to push even higher if the Kremlin decides to completely cut off Russian gas exports into Europe.

Cornwall Insight’s projection does not include a separate six-month initiative to cap costs for companies, charities and public sector organisations, which is forecast to cost £22bn to £48bn.

The consultancy’s chief executive, Gareth Miller, said the £70bn range in its forecasts reflected “a febrile wholesale market continuing to be beset by geopolitical instability, sensitivity to demand, weather and infrastructure resilience”.

He said: “Fortune befriends the bold, but it also favours the prepared. The large uncertainties around commodity markets over the next two years means that the government could get lucky with costs coming out at the low end of the range, but the opposite could also be true.

“In each case, the government may find itself passengers to circumstances outside its control, having made policy that is a hostage to surprises, events and volatile factors. That’s a difficult position to be in.”

The government has faced criticism, as some British MPs urge tighter limits on prices, that the policy is effectively a “blank cheque” and is not targeted at the most vulnerable in society.

Concerns over how Truss and Kwarteng intend to fund a series of measures, including the price guarantee, have spooked financial markets.

The EU, which has outlined possible gas price cap strategies in recent proposals, said last week it planned to cap the revenues of low-carbon electricity generators at €180 a megawatt hour, which is less than half current market prices. Truss has so far resisted calls to extend a levy on North Sea oil and gas operators to electricity generators, who have benefited from a link between gas and electricity prices in Britain.

Truss hopes to strike voluntary long-term deals with generators including Centrica and EDF, alongside the government’s Energy Security Bill measures, to bring down wholesale prices.

The Financial Times reported on Tuesday that the government has threatened companies with legislation to cap their revenues if voluntary deals cannot be agreed.

Affordable, safe' nuclear power is key to reaching Canada's climate goals: federal minister

Canada Nuclear Power Expansion highlights SMRs, clean energy, net-zero targets, and robust regulation to deliver safe, reliable baseload electricity, spur investment, and economically decarbonize remote communities, mines, and grids across provinces securely.

 

Key Points

Canada Nuclear Power Expansion grows SMRs and reactors to meet climate targets with safe, reliable baseload power.

✅ Deploys SMRs for remote communities, mines, and industrial sites

✅ Streamlines regulation to ensure safety, trust, and timely approvals

✅ Provides clean, reliable baseload to hit net-zero electricity goals

 

Canada must expand its nuclear power capacity if it is to reach its climate targets, according to Canadian Minister of Natural Resources Seamus Oregan.

Speaking to the Canadian Nuclear Association’s annual conference, Seamus O’Regan said the industry has to grow.

“As the world tackles a changing climate, nuclear power is poised to provide the next wave of clean, affordable, safe and reliable power,” he told a packed room.

The Ottawa conference was the largest the industry has run with dozens of companies and more than 900 people in attendance. Provincial cabinet ministers from Saskatchewan and Ontario were also there. Those two provinces, along with New Brunswick, signed a memorandum in December as part of a premiers' nuclear initiative to work together on small modular reactor technology.

People need to know that it’s safe

Small modular reactors are units that produce less power than large generating stations, but can be constructed easier and are expected to be safer to operate. Canadian firms have about a dozen of the proposed reactors working their way through the regulatory process, with New Brunswick's SMR plans drawing scrutiny.

The smaller reactors could be used in groups to replace large units, but the industry also hopes to use them in rural or isolated communities, mines or even oilsands projects, potentially replacing the diesel power generators some remote communities use.

The Canadian government issued a road map to support the industry in 2018 and O’Regan committed Thursday to putting some teeth on that proposal later this year, as provinces like Ontario explore new large-scale nuclear plants to meet demand, with specific steps the government will take.

“We have been working so hard to support this industry. We are placing nuclear energy front and centre, something that has never been done before.”

O’Regan said the government’s role is a clear, streamlined regulatory system that will promote the industry, but also help the Canadian public to trust the reactors will be safe.

“People need to know that it’s safe. They need to know that it’s regulated. They need to know that it’s safe for them,” he said.

The Liberals promised during the campaign that they would gradually reduce Canada’s carbon emissions even after hitting the targets in the Paris Agreement by 2030. By 2050, Prime Minister Justin Trudeau said he expects Canada to be carbon neutral, mindful of lessons from Europe's power crisis on reliability.

The government hasn’t outlined how it will achieve that goal. O’Regan said more detail is coming, but it’s clear that nuclear is going to have to play a major part, echoing the UK’s green industrial revolution approach to reactor deployment.

“I have not seen a credible plan for net zero without nuclear as part of the mix. I don’t think we are going to be relying on any one technology. I think it’s going to be a whole host of things.”

O’Regan said large investors are looking for countries that are on the path to net zero.

“Everybody has their shirt sleeves rolled up and we know we need to work on this, not only do we have to work on this for the urgency of the planet, but we have to work on it for Canadian jobs.”

He added, “We must focus on those areas where Canada can and should lead, like nuclear.”

Canadians are ready to take a fresh look at nuclear

John Gorman, president of the Canadian Nuclear Association, said he was thrilled with O’Regan’s comments.

“I took the minister’s remarks this morning as being perhaps the strongest language of support for the nuclear industry in a number of years.”

Gorman said the industry is in strong shape and is working with utility companies such as Ontario Power Generation and regulators to move projects forward.

“It’s this amazing collaboration and coordination that is enabling us to beat others to the roll out of these small modular reactors,” he said.

He said provinces that might not have looked at nuclear before now have an incentive to do it, because of climate change. A former solar industry executive, Gorman said solar and wind power are important, as Ontario plans to seek new wind and solar power to ease supply pressures, but they won’t be able to keep up with rising power demands.

“Globally we are seeing increased recognition that climate change is real and that it’s a crisis, we are also seeing recognition that we are not making as much progress on decarbonizing our electricity system as we thought,” he said. “Canadians are ready to take a fresh look at nuclear and see the real facts.”

Net-zero roadmap can cut electricity costs by a third in Germany - Wartsila

Germany net-zero roadmap charts coal phase-out by 2030, rapid renewables buildout, energy storage, and hydrogen-ready gas engines to cut emissions and lower LCOE by 34%, unlocking a resilient, flexible, low-cost power system by 2040.

 

Key Points

Plan to phase out coal by 2030 and gas by 2040, scaling renewables, storage, and hydrogen to cut LCOE and emissions.

✅ Coal out by 2030; gas phased 2040 with hydrogen-ready engines

✅ Add 19 GW/yr renewables; 30 GW storage by 2040

✅ 34% lower LCOE, 23% fewer emissions vs slower path

 

Germany can achieve significant reductions in emissions and the cost of electricity by phasing out coal in 2030 under its coal phase-out plan but must have a clear plan to ramp up renewables and pivot to sustainable fuels in order to achieve net-zero, according to a new whitepaper from Wartsila.

The modelling, published in Wärtsilä new white paper ‘Achieving net-zero power system in Germany by 2040’, compares the current plan to phase out coal by 2030 and gas by 2045 with an accelerated plan, where gas is phased out by 2040. By accelerating the path to net-zero, Germany can unlock a 34% reduction in the levelised cost of energy, as well as a 23% reduction in the total emissions, or 562 million tonnes of carbon dioxide in real terms.

The modelling offers a clear, three-step roadmap to achieve net-zero: rapidly increase renewables, energy storage and begin future-proofing gas engines in this decade; phase out coal by 2030; and phase out gas by 2040, converting remaining engines to run on sustainable fuels.

The greatest rewards are available if Germany front-loads decarbonisation. This can be done by rapidly increasing renewable capacity, adding 19 GW of wind and solar PV capacity per year. It must also add a total of 30GW of energy storage by 2040.

Håkan Agnevall, President and CEO of Wärtsilä Corporation said: “Germany stands on the precipice of a new, sustainable energy era. The new Federal Government has indicated its plans to consign coal to history by 2030. However, this is only step one. Our white paper demonstrates the need to implement a three-step roadmap to achieve net-zero. It is time to put a deadline on fossil fuels and create a clear plan to transition to sustainable fuels.”

While a rapid coal phase-out has been at the centre of recent climate policy debates, including the ongoing nuclear debate over Germany’s energy mix, the pathway to net-zero is less clear. Wärtsilä’s modelling shows that gas engines should be used to accelerate the transition by providing a short-term bridge to enable net zero and navigate the energy transition while balancing the intermittency of renewables until sustainable fuels are available at scale.

However, if Germany follows the slower pathway and reaches net-zero by 2045, it risks becoming reliant on gas as baseload power for much of the 2030s amid renewable expansion challenges that persist, potentially harming its ability to reach its climate goals. 

Creating the infrastructure to pivot to sustainable fuels is one of the greatest challenges facing the German system. The ability to convert existing capacity to run purely on hydrogen via hydrogen-ready power plants will be key to reaching net-zero by 2040 and unlocking the significant system-wide benefits on offer.

Jan Andersson, General Manager of Market Development in Germany, Wärtsilä Energy added: “To reach the 2040 target and unlock the greatest benefits, the most important thing that Germany can do is build renewables now. 19 GW is an ambitious target, but Germany can do it. History shows us that Germany has been able to achieve high levels of renewable buildout in previous years. It must now reach those levels consistently.

“Creating a clear plan which sets out the steps to net zero is essential. Renewable energy is inherently intermittent, so flexible energy capacity will play a vital role. While batteries provide effective short-term flexibility, gas is currently the only practical long-term option. If Germany is to unlock the greatest benefits from decarbonisation, it must have a clear plan to integrate sustainable fuel. From 2030, all new thermal capacity must run solely on hydrogen.”

Analysis of the last decade demonstrates that the rapid expansion of renewable energy is possible, and that renewables overtook coal and nuclear in generation. Previously, Germany has built large amounts of renewable capacity, including 8GW of solar PV in 2010 and 2011, 5.3 GW of onshore wind in 2017, and 2.5 GW of offshore wind in 2015.

The significant reductions in the cost of electricity demonstrated in the modelling are driven by the fact that renewables are far cheaper to run than coal or gas plants, even as coal still provides about a third of electricity in Germany. The initial capital investment is far outweighed by the ongoing operational expense of fossil fuel-based power.

As well as reducing emissions and costs, Germany’s rapid path to net-zero can also unlock a series of additional benefits. If coal is phased out by 2030 but capacity is not replaced by high levels of renewable energy, Germany risks becoming a significant energy importer, peaking at 162 TWh in 2035. The accelerated pathway would reduce imports by a third.

Likewise, more renewable energy will help to electrify district heating, meaning Germany can move away from carbon-intensive fuels sooner. If Germany follows the accelerated path, 57% of Germany’s heating could be electrified in 2045, compared to 10% under the slower plan.

Jan Andersson concluded: “The opportunities on offer are vast. Germany can provide the blueprint for net zero and galvanise an entire continent. Now is the time for the new government to seize the initiative.”
