Rolls-Royce and Exelon UKSMR Partnership accelerates factory-built small modular reactors, nuclear power, clean energy, 440MW units, advanced manufacturing, fleet deployment, net zero goals, and resilient, low-cost baseload generation in the UK and globally.

Key Points

A partnership to deploy factory-built SMR stations, providing 440MW low-carbon baseload for the UK and export markets.

✅ 440MW factory-built SMR units with rapid modular assembly

✅ Exelon to operate and enhance high capacity factors

✅ Supports UK net zero, jobs, and export-led manufacturing

Rolls-Royce and Exelon Generation have signed a Memorandum of Understanding to pursue the potential for Exelon Generation to operate compact nuclear power stations both in the UK and internationally, including markets such as Canada where New Brunswick SMR questions are prompting public debate today.

Exelon Generation will be using their operational experience to assist Rolls Royce in the development and deployment of the UKSMR.

Rolls-Royce is leading a consortium that is designing a low-cost factory built nuclear power station, known as a small modular reactor (SMR), with UK mini-reactor approval anticipated as development progresses. Its standardised, factory-made components and advanced manufacturing processes push costs down, while the rapid assembly of the modules and components inside a weatherproof canopy on the power station site itself avoid costly schedule disruptions.

The consortium is working with its partners and UK Government to secure a commitment for a fleet of factory built nuclear power stations, each providing 440MW of electricity, to be operational within a decade, helping the UK meet its net zero obligations in line with the green industrial revolution policy set out by government. A fleet deployment in the UK will lead to the creation of new factories that will make the components and modules which will help the economy recover from the Covid-19 pandemic and pave the way for significant export opportunities as well.

The consortium members feature the best of nuclear engineering, construction and infrastructure expertise in Assystem, Atkins, BAM Nuttall, Jacobs, Laing O'Rourke, National Nuclear Laboratory, Nuclear Advanced Manufacturing Research Centre, Rolls-Royce and TWI. Exelon will add valuable operational experience to the team.

Tom Samson, interim Chief Executive Officer of the UKSMR consortium, said: 'Nuclear power is central to tackling climate change and economic recovery, but it must be affordable, reliable and investable and the way we manufacture and assemble our power station brings its cost down to be comparable with offshore wind.

'It's a compelling proposition that could draw new players into the UK's power generation landscape, improving choice for consumers and providing uninterrupted low carbon energy to homes and businesses.

'The opportunity to partner with Exelon is a very exciting prospect for our program, complementing our existing Consortium partnerships with one of the world's largest nuclear operator adds an important dimension to our growth ambitions, embodies the strength of the UK and USA alliance on nuclear matters and reflects wider international moves, such as a Canadian premiers' SMR initiative to accelerate technology development, and offers our future customers the ability to achieve the highest performance standards associated with Exelon's outstanding operational track record.'

The power stations will be built by the UKSMR consortium, before being handed over to be operated by power generation companies. Exelon Generation will work closely with the consortium during the pre-operation period. Exelon Nuclear operates 21 nuclear reactors in America, and U.S. regulators recently issued a final safety evaluation for a NuScale SMR that underscores momentum in the sector. The Exelon nuclear fleet is an integral part of the U.S. clean power mix; it produces more than 158 million megawatt-hours of clean electricity every year.

Bryan Hanson, EVP and COO of Exelon Generation said: 'We believe that SMRs are a crucial part of the world's clean energy mix, as projects like Darlington SMRs advance in Ontario. With our experience both in the US and internationally, Exelon is confident that we can help Rolls Royce ensure SMRs play a key role in the UK's energy future. We've had a very strong record of performance for 20 consecutive years, with a 2019 capacity factor of 95.7 percent. We will leverage this experience to achieve sustainably high capacity factors for the UKSMRs.'

Ralph Hunter, Managing Director of Exelon Nuclear Partners, who runs Exelon's international clean energy business, said: 'We have a strong track record of success to be the operator of choice for the UKSMR. We will help develop operational capability, training and human capacity development in the UK, as utilities such as Ontario Power Generation commit to SMRs abroad, ensuring localisation of skills and a strong culture of safety, performance and efficiency.'

By 2050 a full UK programme of a fleet of factory built nuclear power stations in the UK could create:

Up to 40,000 jobs GBP52BN of value to the UK economy GBP250BN of exports

The current phase of the programme has been jointly funded by all consortium members and UK Research and Innovation.

Twin States Clean Energy Link connects New England to Hydro-Quebec via a 1,200 MW transmission line, DOE-backed capacity, underground segments, existing corridors, boosting renewable energy reliability across Vermont and New Hampshire with cross-border grid flexibility.

Key Points

DOE-backed 1,200 MW line linking Hydro-Quebec to New England, adding clean capacity with underground routes.

✅ 1,200 MW cross-border capacity for the New England grid

✅ Uses existing corridors; underground in VT and northern NH

✅ DOE capacity contract lowers risk and spurs investment

A proposal to build a new transmission line to connect New England with Canadian hydropower is one step closer to reality.

The U.S. Department of Energy announced Monday that it has selected the Twin States Clean Energy Link as one of three transmission projects that will be part of its $1.3 billion cross-border transmission initiative to add capacity to the grid.

WBUR is a nonprofit news organization. Our coverage relies on your financial support. If you value articles like the one you're reading right now, give today.

Twin States is a proposal from National Grid, a utility company that serves Massachusetts, New York, and Rhode Island, and also owns transmission in England and Wales as the region advances projects like the Scotland-to-England subsea link that expand renewable flows, and the non-profit Citizens Energy Corporation.

The transmission line would connect New England with power from Hydro-Quebec, moving into the United States from Canada in Northern Vermont and crossing into New Hampshire near Dalton. It would run through parts of Grafton, Merrimack, and Hillsborough counties, routing through a substation in Dunbarton and ending at a proposed new substation in Londonderry. (Here's a map of the Twin States proposal.)

The federal funding will allow the U.S. Department of Energy to purchase capacity on the planned transmission line, which officials say reduces the risk for other investors and can help encourage others to purchase capacity.

The project has gotten support from local officials in Vermont and New Hampshire, but there are still hurdles to cross. The contract negotiation process is beginning, National Grid said, and the proposal still needs approvals from regulators before construction could begin.

First Nations communities in Canada have opposed transmission lines connecting Hydro-Quebec with New England in the past, and the company has faced scrutiny from environmental groups.

What would Twin States look like?
Transmission projects, like the failed Northern Pass proposal, have been controversial in New England, though the Great Northern Transmission Line progressed in Minnesota.

But Reihaneh Irani-Famili, vice president of capital delivery, project management and construction at National Grid, said this one is different because the developers listened to community concerns before planning the project.

“They did not want new corridors of infrastructure, so we made sure that we're using existing right of way,” she said. “They did not want the visual impact and some of the newer corridors of infrastructure, we're making sure we're undergrounding portions of the line.”

In Vermont and northern New Hampshire, the transmission lines would be buried underground along state roads. South of Littleton, they would be located within existing transmission corridors.

The developers say the lines could provide 1,200 megawatts of transmission capacity. The project would have the ability to carry electricity from hydro facilities in Quebec to New England, and would also be able to bring electricity from New England into Quebec, a step toward broader macrogrid connectivity across regions.

“Those hydro dams become giant green batteries for the region, and they hold that water until we need the electrons,” Irani-Famili said. “So if you think about our energy system not as one that sees borders, but one that sees resources, this is connecting the Quebec resources to the New England resources and helping all of us get into that cleaner energy future with a lot less build than we otherwise would have.”

Irani-Famili says the transmission line could help facilitate more clean energy resources like offshore wind coming online. In a report released last week by New Hampshire’s Department of Energy, authors said importing Canadian hydropower could be one of the most cost-effective ways to move away from fossil fuels on the electric grid.

National Grid estimates the project will help save energy customers $8.3 billion in its first 12 years. The developers are constructing a $260 million “community benefits plan” that would take some profits from the transmission line and give that money back to communities that host the transmission lines and environmental justice communities in New England.

Miami Valley Windstorm Power Outages disrupted thousands as 60 mph gusts toppled trees, downed power lines, and damaged buildings. Utility crews and emergency services managed debris, while NWS alerts warned of extended restoration.

Key Points

Region-wide power losses from severe winds in the Miami Valley, causing damage, debris, and restoration.

✅ 60 mph gusts downed trees, snapped lines, blocked roads

✅ Crews from DP&L worked extended shifts to restore service

✅ NWS issued wind advisories; schools, businesses closed

On a recent day, powerful winds tore through the Miami Valley, causing significant disruption across the region. The storm, which was accompanied by gusts reaching dangerous speeds, led to windstorm power outages affecting thousands of homes and businesses. As trees fell and power lines were snapped, many residents found themselves without electricity for hours, and in some cases, even days.

The high winds, which were part of a larger weather system moving through the area, left a trail of destruction in their wake. In addition to power outages, there were reports of storm damage to buildings, vehicles, and other structures. The force of the wind uprooted trees, some of which fell on homes and vehicles, causing significant property damage. While the storm did not result in any fatalities, the destruction was widespread, with many communities experiencing debris-filled streets and blocked roads.

Utility companies in the Miami Valley, including Dayton Power & Light, quickly mobilized crews, similar to FPL's storm response in major events, to begin restoring power to the affected areas. However, the high winds presented a challenge for repair crews, as downed power lines and damaged equipment made restoration efforts more difficult. Many customers were left waiting for hours or even days for their power to be restored, and some neighborhoods were still experiencing outages several days after the storm had passed.

In response to the severe weather, local authorities issued warnings to residents, urging them to stay indoors and avoid unnecessary travel. Wind gusts of up to 60 miles per hour were reported, making driving hazardous, particularly on bridges and overpasses, similar to Quebec windstorm outages elsewhere. The National Weather Service also warned of the potential for further storm activity, advising people to remain vigilant as the system moved eastward.

The impact of the storm was felt not only in terms of power outages but also in the strain it placed on emergency services. With trees blocking roads and debris scattered across the area, first responders were required to work quickly and efficiently to clear paths and assist those in need. Many residents were left without heat, refrigeration, and in some cases, access to medical equipment that relied on electricity.

Local schools and businesses were also affected by the storm. Many schools had to cancel classes, either due to power outages or because roads were impassable. Businesses, particularly those in the retail and service sectors, faced disruptions in their operations as they struggled to stay open without power amid extended outages that lingered, or to address damage caused by fallen trees and debris.

In the aftermath of the storm, Miami Valley residents are working to clean up and assess the damage. Many homeowners are left dealing with the aftermath of tree removal, property repairs, and other challenges. Meanwhile, local governments are focusing on restoring infrastructure, as seen after Toronto's spring storm outages in recent years, and ensuring that the power grid is secured to prevent further outages.

While the winds have died down and conditions have improved, the storm’s impact will be felt for weeks to come, reflecting Florida's weeks-long restorations after severe storms. The region will continue to recover from the damage, but the event serves as a reminder of the power of nature and the resilience of communities in the face of adversity. For residents affected by the power outages, recovery will require patience as utility crews and local authorities work tirelessly to restore normalcy.

Looking ahead, experts are urging residents to prepare for the next storm season by ensuring that they have emergency kits, backup generators, and contingency plans in place. As climate change contributes to more extreme weather events, it is likely that storms of this magnitude will become more frequent. By taking steps to prepare in advance, communities across the Miami Valley can better handle whatever challenges come next.

UK Coal-Free Energy Transition highlights the West Burton A closure, accelerating renewable energy, wind, solar, nuclear, energy storage, smart grid upgrades, decarbonization, and net-zero goals while ensuring reliability, affordability, and a just transition for workers.

Key Points

A nationwide shift from coal power to renewables, storage, and nuclear to meet net-zero while maintaining reliability.

✅ West Burton A closure ends UK coal-fired generation

✅ Wind, solar, nuclear, storage strengthen grid resilience

✅ Government backs a just transition and worker retraining

The United Kingdom marks a historic turning point in its energy transition with the closure of the West Burton A Power Station in Nottinghamshire. This coal-fired power plant, once a symbol of the nation's industrial might, has now delivered its final watts of electricity to the grid, signalling the end of coal power generation in the UK.

A Landmark Shift Towards Clean Energy

The closure of West Burton A reflects a dramatic shift in the UK's energy landscape. Coal, the backbone of the UK's power generation for decades, is being phased out in favour of renewable energy sources like wind, solar, and nuclear. This transition aligns with the UK's ambitious net-zero emissions target, which aims to radically decarbonize the country's economy by 2050, though progress can falter, as when low-carbon generation stalled in 2019 amid changing market conditions.

Changing Energy Landscape

In the past, coal-fired power plants provided reliable, on-demand power. However, growing awareness of their significant environmental impact, particularly their contribution to climate change,  has accelerated the move away from coal. The UK government has set clear targets for eliminating coal power generation, and the industry has seen a steady decline as the share of coal fell to record lows in the electricity system.

Renewables Fill the Gap

The remarkable growth of renewable energy sources has enabled the transition away from coal. Wind and solar power, in particular, have experienced rapid development and falling costs, and in 2016 wind generated more electricity than coal for the first time. The UK now boasts substantial offshore and onshore wind farms and extensive solar installations. Additionally, investments in nuclear power and emerging energy storage technologies are increasing the reliability and diversity of the UK's power grid.

Economic and Social Impacts

The closure of the last coal-fired power station carries both economic and social impacts. While this change represents a victory for environmentalists, marked by milestones like a full week without coal power in Britain, the end of coal mining and power generation will lead to job losses in communities traditionally reliant on these industries.  The government has committed to supporting affected regions and facilitating a "just transition" for workers by retraining and creating new opportunities in the clean energy sector.

Global Implications

The UK's commitment to a coal-free future serves as a powerful example for other nations seeking to decarbonize their energy systems, including peers where Alberta's last coal plant closed recently. The nation's experience demonstrates that a transition to renewable energy sources is both possible and necessary. However, it also highlights the importance of careful planning and addressing the social and economic impacts of such a rapid energy revolution.

The Road Ahead

While the closure of West Burton A Power Station marks a historic milestone, the UK's transition to clean energy is far from complete. Maintaining a reliable and affordable energy supply, even as coal-free power records raise questions about energy bills, will require continued investment in renewable energy sources, energy storage, and advanced grid technologies.

New England oil-fired generation surges as ISO New England manages a cold snap, dual-fuel switching, and a natural gas price spike, highlighting winter reliability challenges, LNG and pipeline limits, and rising CO2 emissions.

Key Points

Reliance on oil-burning power plants during winter demand spikes when natural gas is costly or constrained.

✅ Driven by dual-fuel switching amid high natural gas prices

✅ ISO-NE winter reliability rules encourage oil stockpiles

✅ Raises CO2 emissions despite coal retirements and renewables growth

New England is relying on oil-fired generators for the most electricity since 2018 as a frigid blast boosts demand for power and natural gas prices soar across markets. 

Oil generators were producing more than 4,200 megawatts early Thursday, accounting for about a quarter of the grid’s power supply, according to ISO New England. That was the most since Jan. 6, 2018, when oil plants produced as much as 6.4 gigawatts, or 32% of the grid’s output, said Wood Mackenzie analyst Margaret Cashman.  

Oil is typically used only when demand spikes, because of higher costs and emissions concerns. Consumption has been consistently high over the past three weeks as some generators switch from gas, which has surged in price in recent months. New England generators are producing power from oil at an average rate of almost 1.8 gigawatts so far this month, the highest for January in at least five years. 

Oil’s share declined to 16% Friday morning ahead of an expected snowstorm, which was “a surprise,” Cashman said. 

“It makes me wonder if some of those generators are aiming to reserve their fuel for this weekend,” she said.

During the recent cold snap, more than a tenth of the electricity generated in New England has been produced by power plants that haven’t happened for at least 15 years.

Burning oil for electricity was standard practice throughout the region for decades. It was once our most common fuel for power and as recently as 2000, fully 19% of the six-state region’s electricity came from burning oil, according to ISO-New England, more than any other source except nuclear power at the time.

Since then, however, natural gas has gotten so cheap that most oil-fired plants have been shut or converted to burn gas, to the point that just 1% of New England’s electricity came from oil in 2018, whereas about half our power came from natural gas generation regionally during that period. This is good because natural gas produces less pollution, both particulates and greenhouse gasses, although exactly how much less is a matter of debate.

But as you probably know, there’s a problem: Natural gas is also used for heating, which gets first dibs. Prolonged cold snaps require so much gas to keep us warm, a challenge echoed in Ontario’s electricity system as supply tightens, that there might not be enough for power plants – at least, not at prices they’re willing to pay.

After we came close to rolling brownouts during the polar vortex in the 2017-18 winter because gas-fired power plants cut back so much, ISO-NE, which has oversight of the power grid, established “winter reliability” rules. The most important change was to pay power plants to become dual-fuel, meaning they can switch quickly between natural gas and oil, and to stockpile oil for winter cold snaps.

We’re seeing that practice in action right now, as many dual-fuel plants have switched away from gas to oil, just as was intended.

That switch is part of the reason EPA says the region’s carbon emissions have gone up in the pandemic, from 22 million tons of CO2 in 2019 to 24 million tons in 2021. That reverses a long trend caused partly by closing of coal plants and partly by growing solar and offshore wind capacity: New England power generation produced 36 million tons of CO2 a decade ago.

So if we admit that a return to oil burning is bad, and it is, what can we do in future winters? There are many possibilities, including tapping more clean imports such as Canadian hydropower to diversify supply.

The most obvious solution is to import more natural gas, especially from fracked fields in New York state and Pennsylvania. But efforts to build pipelines to do that have been shot down a couple of times and seem unlikely to go forward and importing more gas via ocean tanker in the form of liquefied natural gas (LNG) is also an option, but hits limits in terms of port facilities.

Aside from NIMBY concerns, the problem with building pipelines or ports to import more gas is that pipelines and ports are very expensive. Once they’re built they create a financial incentive to keep using natural gas for decades to justify the expense, similar to moves such as Ontario’s new gas plants that lock in generation. That makes it much harder for New England to decarbonize and potentially leaves ratepayers on the hook for a boatload of stranded costs.

Ukraine Electricity Exports resume to the European grid, starting with Moldova and expanding to Poland, Slovakia, and Romania, signaling energy security, grid resilience, added megawatts, and recovery after Russian strikes with support and renewables.

Key Points

Ukraine Electricity Exports are resumed sales of surplus power to EU neighbors, reflecting grid recovery and resilience.

✅ Initial deliveries to Moldova; Poland, Slovakia, Romania to follow.

✅ Extra capacity from repairs, warmer demand, and renewables.

✅ Exports may vary amid ongoing Russian strikes risk.

Ukraine began resuming electricity exports to European countries on Tuesday, its energy minister said, a dramatic turnaround from six months ago when fierce Russian bombardment of power stations plunged much of the country into darkness in a bid to demoralize the population.

The announcement by Energy Minister Herman Halushchenko that Ukraine was not only meeting domestic consumption demands but also ready to restart exports to its neighbors was a clear message that Moscow’s attempt to weaken Ukraine by targeting its infrastructure did not work.

Ukraine’s domestic energy demand is “100%” supplied, he told The Associated Press in an interview, and it has reserves to export due to the “titanic work” of its engineers and international partners.

Russia ramped up infrastructure attacks in September, when waves of missiles and exploding drones destroyed about half of Ukraine’s energy system. Power cuts were common across the country as temperatures dropped below freezing and tens of millions struggled to keep warm.

Moscow said the strikes were aimed at weakening Ukraine’s ability to defend itself, and has also moved to reactivate the Zaporizhzhia plant through new power lines, while Western officials said the blackouts that caused civilians to suffer amounted to war crimes. Ukrainians said the timing was designed to destroy their morale as the war marked its first anniversary.

Ukraine had to stop exporting electricity in October to meet domestic needs.

Engineers worked around the clock, often risking their lives to come into work at power plants and keep the electricity flowing. Kyiv’s allies also provided help. In December, U.S. Secretary of State Antony Blinken announced $53 million in bilateral aid to help the country acquire electricity grid equipment, and USAID mobile gas turbine plant support, on top of $55 million for energy sector support.

Much more work remains to be done, Halushchenko said. Ukraine needs funding to repair damaged generation and transmission lines, and revenue from electricity exports would be one way to do that.

The first country to receive Ukraine’s energy exports will be Moldova, he said.

Besides the heroic work by engineers and Western aid, warmer temperatures are enabling the resumption of exports by making domestic demand lower, even as Germany’s coal generation shapes regional power flows.

Renewables like solar and wind power also come into play as temperatures rise, taking some pressure off nuclear and coal-fired power plants.

But it’s unclear if Ukraine can keep up exports amid the constant threat of Russian bombardment, with any potential agreement on power plant attacks still uncertain.

“Unfortunately now a lot of things depend on the war,” Halushchenko said. “I would say we feel quite confident now until the next winter.”

Exports to Poland, Slovakia and Romania are also on schedule to resume, he said.

“Today we are starting with Moldova, and we are talking about Poland, we are talking about Slovakia and Romania,” Halushchenko added, noting that how much will depend on their needs.

“For Poland, we have only one line that allows us to export 200 megawatts, but I think this month we will finish another line which will increase this to an additional 400 MW, so these figures could change,” he said.

Export revenue will depend on fluctuating electricity prices in Europe, where stunted hydro and nuclear output may affect recovery. In 2022, while Ukraine was still able to export energy, Ukrainian companies averaged 40 million to 70 million euros a month depending on prices, Halushchenko said.
