Edison to decommission coal-fired Nevada power plant

Small Modular Reactors in Canada are advancing through provincial collaboration, offering nuclear energy, clean power and carbon reductions for grids, remote communities, and mines, with factory-built modules, regulatory roadmaps, and pre-licensing by the nuclear regulator.

Key Points

Compact, factory-built nuclear units for clean power, cutting carbon for grids, remote communities, and industry.

✅ Provinces: Ontario, Saskatchewan, New Brunswick collaborate

✅ Targets coal replacement, carbon cuts, clean baseload power

✅ Modular, factory-made units; 5-10 year deployment horizon

The premiers of Ontario, Saskatchewan and New Brunswick have committed to collaborate on developing nuclear reactor technology in Canada. 

Doug Ford, Scott Moe and Blaine Higgs made the announcement and signed a memorandum of understanding on Sunday in advance of a meeting of all the premiers. 

They will be working on the research, development and building of small modular reactors as a way to help their individual provinces reduce carbon emissions and move away from non-renewable energy sources like coal. 

Small modular reactors are easy to construct, are safer than large reactors and are regarded as cleaner energy than coal, the premiers say. They can be small enough to fit in a school gym. 

SMRs are actually not very close to entering operation in Canada, though Ontario broke ground on its first SMR at Darlington recently, signaling early progress. Natural Resources Canada released an "SMR roadmap" last year, with a series of recommendations about regulation readiness and waste management for SMRs.

In Canada, about a dozen companies are currently in pre-licensing with the Canadian Nuclear Safety Commission, which is reviewing their designs.

"Canadians working together, like we are here today, from coast to coast, can play an even larger role in addressing climate change in Canada and around the world," Moe said.  

Canada's Paris targets are to lower total emissions 30 per cent below 2005 levels by 2030, and nuclear's role in climate goals has been emphasized by the federal minister in recent remarks. Moe says the reactors would help Saskatchewan reach a 70 per cent reduction by that year.

The provinces' three energy ministries will meet in the new year to discuss how to move forward and by the fall a fully-fledged strategy for the reactors is expected to be ready.

However, don't expect to see them popping up in a nearby field anytime soon. It's estimated it will take five to 10 years before they're built. 

Ford lauds economic possibilities
The provincial leaders said it could be an opportunity for economic growth, estimating the Canadian market for this energy at $10 billion and the global market at $150 billion.

Ford called it an "opportunity for Canada to be a true leader." At a time when Ottawa and the provinces are at odds, Higgs said it's the perfect time to show unity. 

"It's showing how provinces come together on issues of the future." 

P.E.I. premier predicts unity at Toronto premiers' meeting
No other premiers have signed on to the deal at this point, but Ford said all are welcome and "the more, the merrier."

But developing new energy technologies is a daunting task. Higgs admitted the project will need national support of some kind, though he didn't specify what. The agreement signed by the premiers is also not binding. 

About 8.6 per cent of Canada's electricity comes from coal-fired generation. In New Brunswick that figure is much higher — 15.8 per cent — and New Brunswick's small-nuclear debate has intensified as New Brunswick Premier Blaine Higgs has said he worries about his province's energy producers being hit by the federal carbon tax.

Ontario has no coal-fired power plants, and OPG's SMR commitment aligns with its clean electricity strategy today. In Saskatchewan, burning coal generates 46.6 per cent of the province's electricity.

How would it work?
The federal government describes small modular reactors (SMRs) as the "next wave of innovation" in nuclear energy technology, and collaborations like the OPG and TVA partnership are advancing development efforts, and an "important technology opportunity for Canada."

Traditional nuclear reactors used in Canada typically generate about 800 megawatts of electricity, and Ontario is exploring new large-scale nuclear plants alongside SMRs, or enough to power about 600,000 homes at once (assuming that 1 megawatt can power about 750 homes).

The International Atomic Energy Agency (IAEA), the UN organization for nuclear co-operation, considers a nuclear reactor to be "small" if it generates under 300 megawatts.

Designs for small reactors ranging from just 3 megawatts to 300 megawatts have been submitted to Canada's nuclear regulator, the Canadian Nuclear Safety Commission, for review as part of a pre-licensing process, while plans for four SMRs at Darlington outline a potential build-out pathway that regulators will assess.

Ford rallying premiers to call for large increase in federal health transfers
Such reactors are considered "modular" because they're designed to work either independently or as modules in a bigger complex (as is already the case with traditional, larger reactors at most Canadian nuclear power plants). A power plant could be expanded incrementally by adding additional modules.

Modules are generally designed to be small enough to make in a factory and be transported easily — for example, via a standard shipping container.

In Canada, there are three main areas where SMRs could be used:

Traditional, on-grid power generation, especially in provinces looking for zero-emissions replacements for CO2-emitting coal plants.
Remote communities that currently rely on polluting diesel generation.
Resource extraction sites, such as mining and oil and gas.

National Grid Demand Flexibility Service helps stabilise the UK grid during tight supply, offering discounts for smart meter users who shift peak-time electricity use, reducing power cut risks amid low wind and import constraints.

Key Points

A National Grid scheme paying smart homes to cut peak-time use, easing supply pressure and avoiding power cuts.

✅ Pays volunteers with smart meters to reduce peak demand.

✅ Credits discounts for shifting use to off-peak windows.

✅ Manages tight margins and helps avert UK power cuts.

National Grid has decided not to activate a scheme on Tuesday to help the UK avoid power cuts after being poised to do so.

It would have seen some households offered discounts on their electricity bills if they cut peak-time use.

National Grid had been ready to trigger the scheme following a warning that Britain's energy supplies were looking tighter than usual this week.

However, it decided that the measure was not required.

Alerts are sent out automatically when expected supplies drop below a certain level. But they do not mean that blackouts are likely, or that the situation is critical.

National Grid said it was "confident" it would be able to manage margins and "demand is not at risk".

Discounts
Earlier on Monday, the grid operator said it was considering whether to pay households across Britain to reduce their energy use to help out on Tuesday evening.

Under the Demand Flexibility Service (DFS), announced earlier this month, customers that have signed up could get discounts on their bills if they use less electricity in a given window of time.

That could mean delaying the use of a tumble-dryer or washing machine, or cooking dinner in the microwave rather than the oven.

Major suppliers such as Octopus and British Gas are taking part, but only customers that have an electricity smart meter and that have volunteered are eligible. About 14 million UK homes have an electricity smart meter.

The DFS has already been tested twice but has not yet run live.

Octopus, the supplier with the most customers signed up, said that some households had earned more than £4 during the hour-long tests, while the average saving was "well over £1".

It came after forecasts projected a large drop in the amount of power that Britain will be able to import from French nuclear power stations on Monday and Tuesday evenings.

The lack of strong winds to power turbines has also affected how much power can be generated within the UK, and efforts to fast-track grid connections aim to ease constraints.

Such warnings are not unusual - around 12 have been issued and cancelled without issue in the last six years, and other regions such as Canada are seeing grids strained by harsh weather as well.

However, they have become more common this year due to the energy crisis, and the most recent notice was sent out last week.

The situation means that the UK will have to import electricity from other sources on Monday and Tuesday evening.

Supplies are also expected be tight in France, forecasters say.

France has been facing months of problems with its nuclear power plants, which generate around three-quarters of the country's electricity.

More than half of the nuclear reactors run by state energy company EDF have closed due to maintenance problems and technical issues.

It has added to a massive energy crisis in Europe which is facing a winter without gas supplies from Russia.

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.

Alberta Clean Electricity Regulations face federal mandates and provincial autonomy, balancing greenhouse gas cuts, net-zero 2050 goals, and renewable energy adoption across wind, solar, and hydro, while protecting jobs and economic stability in energy communities.

Key Points

Rules to cut power emissions, boost renewables, and align Alberta with federal net-zero goals under federal mandates.

✅ Phases out coal and curbs greenhouse gas emissions

✅ Expands wind, solar, and hydro to diversify the grid

✅ Balances provincial autonomy with national climate targets

In a recent development, Alberta finds itself at a crossroads between provincial autonomy and federal mandates concerning federal clean electricity regulations that shape long-term planning. The province, known for its significant oil and gas industry, faces increasing pressure to align its energy policies with federal climate goals set by Ottawa.

The federal government, under the leadership of Environment Minister Steven Guilbeault, has proposed regulations aimed at reducing greenhouse gas emissions and transitioning towards a cleaner energy future that prioritizes clean grids and batteries across provinces. These regulations are part of Canada's broader commitment to combat climate change and achieve net-zero emissions by 2050.

The Federal Perspective

From Ottawa's standpoint, stringent regulations on Alberta's electricity sector are necessary to meet national climate targets. This includes measures to phase out coal-fired power plants and increase reliance on renewable energy sources such as wind, solar, and hydroelectric power. Minister Guilbeault emphasizes the importance of these regulations in mitigating Canada's carbon footprint and fostering sustainable development.

Alberta's Response

In contrast, Alberta has historically championed provincial autonomy in energy policy, leveraging its vast fossil fuel resources to drive economic growth. The province remains cautious about federal interventions that could potentially disrupt its energy sector, a cornerstone of its economy, especially amid changes to how electricity is produced and paid for now under discussion.

Premier Jason Kenney has expressed concerns over federal overreach, and his influence over electricity policy has shaped proposals in the legislature. He emphasizes the province's efforts in adopting cleaner technologies while balancing economic stability and environmental sustainability.

The Balancing Act

The challenge lies in finding a middle ground between federal imperatives and provincial priorities, as interprovincial disputes like B.C.'s export-restriction challenge complicate coordination. Alberta acknowledges the need to diversify its energy portfolio and reduce emissions but insists on preserving its jurisdiction over energy policy. The province has already made strides in renewable energy development, including investing in wind and solar projects alongside traditional energy sources.

Economic Implications

For Alberta, the transition to cleaner electricity carries significant economic implications as the electricity market heads for a reshuffle in the coming years. It entails navigating the complexities of energy transition, ensuring job retention, and fostering innovation in sustainable technologies. Critics argue that abrupt federal regulations could exacerbate economic hardships, particularly in communities reliant on the fossil fuel industry.

Moving Forward

As discussions continue between Alberta and Ottawa, finding common ground, including consideration of recent market change proposals from the province, remains essential. Collaborative efforts are necessary to develop tailored solutions that accommodate both environmental responsibilities and economic realities. This includes exploring incentives for renewable energy investment, supporting energy sector workers in transitioning to new industries, and leveraging Alberta's expertise in energy innovation.

Conclusion

Alberta's journey towards clean electricity regulation exemplifies the delicate balance between regional autonomy and federal oversight in Canada's complex federal system. While tensions persist between provincial and federal priorities, both levels of government share a common commitment to addressing climate change and advancing sustainable energy solutions.

The outcome of these negotiations will not only shape Alberta's energy landscape but also influence Canada's overall progress towards a greener future. Finding equitable solutions that respect provincial autonomy while achieving national environmental goals remains paramount in navigating this evolving policy landscape.

Ottawa Sewage Energy Exchange System uses wastewater heat recovery and efficient heat pumps to deliver renewable district energy, zero carbon heating and cooling, cutting greenhouse gas emissions at LeBreton Flats and scaling urban developments.

Key Points

A district energy system recovering wastewater heat via pumps to deliver zero carbon heating and cooling.

✅ Delivers 9 MW heating and cooling for 2.4M sq ft at LeBreton Flats

✅ Cuts 5,066 tonnes CO2e each year, reducing greenhouse gases

✅ Powers Odenak zero carbon housing via district energy

Ottawa is embarking on a groundbreaking initiative to harness the latent thermal energy within its wastewater system, in tandem with advances in energy storage in Ontario that strengthen grid resilience, marking a significant stride toward sustainable urban development. The Sewage Energy Exchange System (SEES) project, a collaborative effort led by the LeBreton Community Utility Partnership—which includes Envari Holding Inc. (a subsidiary of Hydro Ottawa) and Theia Partners—aims to revolutionize how the city powers its buildings.

Harnessing Wastewater for Sustainable Energy

The SEES will utilize advanced heat pump technology to extract thermal energy from the city's wastewater infrastructure, providing both heating and cooling to buildings within the LeBreton Flats redevelopment. This innovative approach eliminates the need for fossil fuels, aligning with Ottawa's commitment to reducing greenhouse gas emissions and promoting clean energy solutions across the province, including the Hydrogen Innovation Fund that supports new low-carbon pathways.

The system operates by diverting sewage from the municipal collection network into an external well, where it undergoes filtration to remove large solids. The filtered water is then passed through a heat exchanger, transferring thermal energy to the building's heating and cooling systems. After the energy is extracted, the treated water is safely returned to the city's sewer system.

Environmental and Economic Impact

Once fully implemented, the SEES is projected to deliver over 9 megawatts of heating and cooling capacity, servicing approximately 2.4 million square feet of development. This capacity is expected to reduce greenhouse gas emissions by approximately 5,066 tonnes annually—equivalent to the electricity consumption of over 3,300 homes for a year. Such reductions are pivotal in helping Ottawa meet its ambitious goal of achieving a 96% reduction in community-wide greenhouse gas emissions by 2040, as outlined in its Climate Change Master Plan and Energy Evolution strategy, and they align with Ontario's plan to rely on battery storage to meet rising demand across the grid.

Integration with the Odenak Development

The first phase of the SEES will support the Odenak development, a mixed-use project comprising two high-rise residential buildings. This development is poised to be Canada's largest residential zero-carbon project, echoing calls for Northern Ontario grid sustainability from community groups, featuring 601 housing units, with 41% designated as affordable housing. The integration of the SEES will ensure that Odenak operates entirely on renewable energy, setting a benchmark for future urban developments.

Broader Implications and Future Expansion

The SEES project is not just a localized initiative; it represents a scalable model for sustainable urban energy solutions that aligns with green energy investments in British Columbia and other jurisdictions. The LeBreton Community Utility Partnership is in discussions with the National Capital Commission to explore extending the SEES network to additional parcels within the LeBreton Flats redevelopment. Expanding the system could lead to economies of scale, further reducing costs and enhancing the environmental benefits.

Ottawa's venture into wastewater-based energy systems places it at the forefront of a growing trend in North America. Cities like Toronto and Vancouver have initiated similar projects, while related pilots such as the EV-to-grid pilot in Nova Scotia highlight complementary approaches, and European counterparts have long utilized sewage heat recovery systems. Ottawa's adoption of this technology underscores its commitment to innovation and sustainability in urban planning.

The SEES project at LeBreton Flats exemplifies how cities can repurpose existing infrastructure to create sustainable, low-carbon energy solutions. By transforming wastewater into a valuable energy resource, Ottawa is setting a precedent for environmentally responsible urban development. As the city moves forward with this initiative, it not only addresses immediate energy needs but also contributes to a cleaner, more sustainable future for its residents, even as the province accelerates Ontario's energy storage push to maintain reliability.

Puerto Rico Power Restoration advances as PREPA, FEMA, and the Army Corps rebuild the grid after Hurricane Maria; 75% of customers powered, amid privatization debate, Whitefish contract fallout, and a continuing island-wide boil-water advisory.

Key Points

Effort to rebuild Puerto Rico's grid and restore power, led by PREPA with FEMA support after Hurricane Maria.

✅ 75.35% of customers have power; 90.8% grid generating

✅ PREPA, FEMA, and Army Corps lead restoration work

✅ Privatization debate, Whitefish contract scrutiny

Nearly six months after Hurricane Maria decimated Puerto Rico, the island's electricity has been restored to 75 percent capacity, according to its utility company, a contrast to California power shutdowns implemented for different reasons.

The Puerto Rico Electric Power Authority said Sunday that 75.35 percent of customers now have electricity. It added that 90.8 percent of the electrical grid, already anemic even before the Sept. 20 storm barrelled through the island, is generating power again, though demand dynamics can vary widely as seen in Spain's power demand during lockdowns.

Thousands of power restoration personnel made up of the Puerto Rico Electric Power Authority (PREPA), the Federal Emergency Management Agency (FEMA), industry workers from the mainland, and the Army Corps of Engineers have made marked progress in recent weeks, even as California power shutoffs highlight grid risks elsewhere.

Despite this, 65 people in shelters and an island-wide boil water advisory is still in effect even though almost 100 percent of Puerto Ricans have access to drinking water, local government records show.

The issue of power became controversial after Puerto Rico Gov. Ricardo Rossello recently announced plans to privatize PREPA after it chose to allocate a $300 million power restoration contract to Whitefish, a Montana-based company with only a few staffers, rather than put it through the mutual-aid network of public utilities usually called upon to coordinate power restoration after major disasters, and unlike investor-owned utilities overseen by regulators such as the Florida PSC on the mainland.

That contract was nixed and Whitefish stopped working in Puerto Rico after FEMA raised "significant concerns" over the procurement process, scrutiny mirrored by the fallout from Taiwan's widespread outage where the economic minister resigned.
