EU Nuclear Reactor Life Extension focuses on energy security, carbon-free electricity, and safety as ageing reactors face gas shortages, high power prices, and regulatory approvals across the UK and EU amid winter supply risks.

Key Points

EU Nuclear Reactor Life Extension is the policy to keep ageing reactors safely generating affordable, low-carbon power.

✅ Extends reactor operation via inspections and component upgrades

✅ Addresses gas shortages, price volatility, and winter supply risks

✅ Requires national regulator approval and cost-benefit analysis

Shaken by the loss of Russian natural gas since the invasion of Ukraine, European countries are questioning whether they can extend the lives of their ageing nuclear reactors to maintain the supply of affordable, carbon-free electricity needed for net-zero across the bloc — but national regulators, companies and governments disagree on how long the atomic plants can be safely kept running.

Europe avoided large-scale blackouts last winter despite losing its largest supplier of natural gas, and as Germany temporarily extended nuclear operations to bolster stability, but industry is still grappling with high electricity prices and concerns about supply.

Given warnings from the International Energy Agency that the coming winters will be particularly at risk from a global gas shortage, governments have turned their attention to another major energy source — even as some officials argue nuclear would do little to solve the gas issue in the near term — that would exacerbate the problem if it too is disrupted: Europe’s ageing fleet of nuclear power plants.

Nuclear accounts for nearly 10% of energy consumed in the European Union, with transport, industry, heating and cooling traditionally relying on coal, oil and natural gas.

Historically nuclear has provided about a quarter of EU electricity and 15% of British power, even as Germany shut down its last three nuclear plants recently, underscoring diverging national paths.

Taken together, the UK and EU have 109 nuclear reactors running, even as Europe is losing nuclear power in several markets, most of which were built in the 1970s and 1980s and were commissioned to last about 30 years.

That means 95 of those reactors — nearly 90% of the fleet — have passed or are nearing the end of their original lifespan, igniting debates over how long they can safely continue to be granted operating extensions, with some arguing it remains a needed nuclear option for climate goals despite age-related concerns.

Regulations differ across borders, with some countries such as Germany turning its back on nuclear despite an ongoing energy crisis, but life extension discussions are usually a once-a-decade affair involving physical inspections, cost/benefit estimates for replacing major worn-out parts, legislative amendments, and approval from the national nuclear safety authority.

NB Power and Hydro-Québec Electricity Agreements expand clean hydroelectric exports, support Mactaquac dam refurbishment, add grid interconnections, and advance decarbonization, climate goals, reliability, and transmission capacity across Atlantic Canada and U.S. markets through 2040.

Key Points

Deals for hydro exports, Mactaquac upgrades, and new interconnections to improve reliability and cut emissions.

✅ 47 TWh to NB by 2040 over existing transmission lines

✅ HQ expertise to address Mactaquac concrete swelling

✅ Talks on new interconnections for Atlantic and U.S. exports

NB Power and Hydro-Quebec have signed three deals that will see Quebec sell more electricity to New Brunswick and provide help with the refurbishment of the Mactaquac hydroelectric generating station.

Under the first agreement, Hydro-Quebec will export 47 terawatt hours of electricity to New Brunswick between now and 2040 over existing power lines — expanding on an agreement in place since 2012 and on related regional agreements such as the Churchill Falls deal in Newfoundland and Labrador.

The second deal will see Hydro-Quebec share expertise for part of the refurbishment of the Mactaquac dam to extend the useful life of the generating station until at least 2068, when the 670 megawatt facility on the St. John River will be 100 years old.

Since the 1980s, concrete portions of the facility have been affected by a chemical reaction that causes the concrete to swell and crack.

Hydro-Quebec has been dealing with the same problem, and has developed expertise in addressing the issue.

“This is why we have signed a technical collaboration agreement between Hydro-Quebec and us for part of the refurbishment of the Mactaquac generating station,” NB Power president Gaetan Thomas said Friday.

Eric Martel, CEO of Hydro-Quebec, said hydroelectric plants provide long-term clean power that’s important in the fight against climate change as the province has ruled out nuclear power for now.

“We understand how important it is to ensure the long term sustainability of these facilities and we are happy to share the expertise that Hydro-Quebec has acquired over the years,” Martel said.

The refurbishment of the Mactaquac generating station is expected to cost between $2.9 billion and $3.5 billion. Once the work begins, each of the facility’s six generators will have to be taken offline for months at a time, and Thomas said that’s where the increased power from Quebec, supported by Hydro-Quebec's capacity expansion in recent years, will come into use.

He expects the power could cost about $100 million per year but will be much cheaper than other sources.

The third agreement calls for talks to begin for the construction of additional power connections between Quebec and New Brunswick to increase exports to Atlantic Canada and the United States, where transmission constraints have limited incremental deliveries in recent years.

“Building new interconnections and allowing for increased power transfer between our systems could be mutually beneficial, even as historic tensions in Newfoundland and Labrador linger. More than ever, we are looking to the future,” Martel said.

“Partnering will permit us to seize new business opportunities together and pool our effort to support de-carbonization, including Hydro-Quebec's non-fossil strategy that is now underway, and fight against climate change, both here and in our neighbourhood market,” he said.

OPG-TVA SMR Partnership advances advanced nuclear technology and small modular reactors for 24/7 carbon-free baseload power, enabling net-zero goals, cross-border licensing, and deployment within a North American clean energy hub.

Key Points

A cross-border effort by OPG and TVA to develop, license, and deploy SMRs for reliable, carbon-free baseload power.

✅ Coordinates design, licensing, construction, and operations

✅ Supports 24/7 baseload, net-zero targets, and energy security

✅ Leverages Darlington and Clinch River early site permits

Two of North America's leading nuclear utilities unveiled a pioneering partnership to develop advanced nuclear technology as an integral part of a clean energy future and creating a North American energy hub. Ontario Power Generation, whose OPG's SMR commitment is well established, and the Tennessee Valley Authority will jointly work to help develop small modular reactors as an effective long-term source of 24/7 carbon-free energy in both Canada and the U.S.

The agreement allows the companies to coordinate their explorations into the design, licensing, construction and operation of small modular reactors.

"As leaders in our industry and nations, OPG and TVA share a common goal to decarbonize energy generation while maintaining reliability and low-cost service, which our customers expect and deserve," said Jeff Lyash, TVA President and CEO. "Advanced nuclear technology will not only help us meet our net-zero carbon targets but will also advance North American energy security."

"Nuclear energy has long been key to Ontario's clean electricity grid, and is a crucial part of our net-zero future," said Ken Hartwick, OPG President and CEO. "Working together, OPG and TVA will find efficiencies and share best practices for the long-term supply of the economical, carbon-free, reliable electricity our jurisdictions need, supported by ongoing Pickering life extensions across Ontario's fleet."

OPG and TVA have similar histories and missions. Both are based on public power models that developed from renewable hydroelectric generation before adding nuclear to their generation mixes. Today, nuclear generation accounts for significant portions of their carbon-free energy portfolios, with Ontario advancing the Pickering B refurbishment to sustain capacity.

Both are also actively exploring SMR technologies. OPG is moving forward with plans to deploy an SMR at its Darlington nuclear facility in Clarington, ON, as part of broader Darlington SMR plans now underway. The Darlington site is the only location in Canada licensed for new nuclear with a completed and accepted Environmental Assessment. TVA currently holds the only Nuclear Regulatory Commission Early Site Permit in the U.S. for small modular reactor deployment at its Clinch River site near Oak Ridge, TN.

No exchange of funding is involved. However, the collaboration agreement will help OPG and TVA reduce the financial risk that comes from development of innovative technology, as well as future deployment costs.

"TVA has the most recent experience completing a new nuclear plant in North America at Watts Bar and that knowledge is invaluable to us as we work toward the first SMR groundbreaking at Darlington," said Hartwick. "Likewise, because we are a little further along in our construction timing, TVA will gain the advantage of our experience before they start work at Clinch River."

"It's a win-win agreement that benefits all of those served by both OPG and TVA, as well as our nations," said Lyash. "Moving this technology forward is not only a significant step in advancing a clean energy future and Canada's climate goals, but also in creating a North American energy hub."

"With the demand for clean electricity on the rise around the world, Ontario's momentum is growing. The world is watching Ontario as we advance our work to fully unleash our nuclear advantage, alongside a premiers' SMR initiative that underscores provincial collaboration. I congratulate OPG and TVA – two great industry leaders – for working together to deploy SMRs and showcase and apply Canada's nuclear expertise that will deliver economic, health and environmental benefits for all of us to enjoy," said Todd Smith, Ontario Minister of Energy.

"The changing climate is a global crisis that requires global solutions. The partnership between the Tennessee Valley Authority and Ontario Power Generation to develop and deploy advanced nuclear technology is exactly the kind of innovative collaboration that is needed to quickly bring the next generation of nuclear carbon-free generation to market. I applaud the leadership that both companies are demonstrating to further strengthen our cross-border relationships," said Maria Korsnick, President and CEO, Nuclear Energy Institute.

DOE Grid Resilience Pricing Rule faces FERC review as energy groups challenge an expedited timeline to reward coal and nuclear for reliability in wholesale markets, impacting natural gas, renewables, baseload economics, and grid pricing.

Key Points

A DOE proposal directing FERC to compensate coal and nuclear plants for reliability attributes in wholesale markets.

✅ Industry coalition seeks normal FERC timeline and review

✅ Impacts wholesale pricing, baseload economics, reliability

✅ Request for 90-day comments and reply period

A coalition of 11 industry groups is pushing back on Energy Secretary Rick Perry's efforts to quickly implement a major change to the way electric power is priced in the United States.

The Energy Department on Friday proposed a rule that stands to bolster coal and nuclear power plants by forcing the regional markets that set electricity prices to compensate them for the reliability they provide. Perry asked the Federal Energy Regulatory Commission to consider and finalize the rule within 60 days, including a 45-day period during which stakeholders can issue comments.

On Monday, groups representing petroleum, natural gas, electric power and renewable energy interests including ACORE urged FERC to reject the expedited process, as well as the Department of Energy's request that the regulatory commission consider putting in place an interim rule.

They say the time frame is "aggressive" and the department didn't provide adequate justification for fast-tracking a process that could have huge impacts on wholesale electricity markets.

"This is one of the most significant proposed rules in decades related to the energy industry and, if finalized, would unquestionably have significant ramifications for wholesale markets under the Commission's jurisdiction," the groups said in the motion filed with FERC.

"The Energy Industry Associations urge the Commission to reject the proposed unreasonable timelines and instead proceed in a manner that would afford meaningful consideration of public comments and be consistent with the normal deliberative process that it typically affords such major undertakings," they said.

The groups are requesting a 90-day comment period, as well as another period for reply comments. FERC, which has authority to regulate interstate transmission and sale of electricity and natural gas, is not required to decide in favor of the rule but, amid a recent FERC decision that drew industry criticism, must consider it.

Expediting the process or imposing an interim rule is generally limited to emergencies, the groups said. The Energy Department's letter to FERC does not even attempt to establish that an immediate threat to U.S. electricity reliability exists, they allege.

• A coalition of energy industry groups asked regulators to reject a rule proposed by the U.S. Department of Energy on Friday.
• The rule would bolster coal-fired and nuclear power plants by requiring wholesale markets to compensate them for certain attributes.
• The groups say the Energy Department proposed "unreasonable timelines" for stakeholders to offer feedback on a rule with "significant ramifications for wholesale markets."

The groups cite a recent Energy Department report on grid reliability that concluded: "reliability is adequate today despite the retirement of 11 percent of the generating capacity available in 2002, as significant additions from natural gas, wind, and solar have come online since then."

The Department of Energy did not return a request for comment.

The Energy Department's rule marks a flashpoint in the battle between natural gas-fired and renewable energy and so-called baseload power sources like coal and nuclear.

Separately, coal and business groups have supported the EPA in litigation over the Affordable Clean Energy rule, as documented in legal challenges brought during the rule's defense.

Gas, wind and solar power have eaten into coal and nuclear's share of U.S. electric power generation in recent years. That is thanks to a boom in U.S. gas production that has pushed down prices, the rapid adoption of subsidized renewable energy and President Barack Obama's efforts to mitigate emissions from power plants, which the Trump administration has sought to replace with a tune-up as policies shift.

Electric power is priced in deregulated, wholesale markets in many parts of the country. Utilities typically draw on the cheapest power sources first.

Some worry that the retirement of coal-fired and nuclear power plants undermines the nation's ability to reliably and affordably deliver electricity to households and businesses.

President Donald Trump has vowed to revive the ailing coal industry, declaring an end to the 'war on coal' in public remarks. Trump, Perry and other administration officials reject the consensus among climate scientists that carbon emissions from sources like coal-fired plants are the primary cause of global warming.
