The head of the Ontario Association of Nuclear Medicine said he began to worry about the reliability of a backup plan to address a looming shortage of medical isotopes after one provider warned of a potential disruption in supply.

Hospitals across the country have been using a medical isotope called Thallium 201 for some heart-related therapies in order to conserve dwindling supplies of the isotope produced by the leaky reactor at Chalk River, Ont. that is expected to remain out of service for at least three months.

“There was a minor disruption in the supply of thallium this week, which we are told has been rectified and we should be in better shape next week,” said Dr. Christopher O’Brien. “That was a surprise to us, when we were told there was insufficient thallium available for all of our cardiac patients.”

Thallium provider GE Healthcare, the company that warned of a potential shortfall in supply, said the disruption was short-lived.

“There was one day that we were going to be a little short but it has been addressed,” said spokesman Ryan Fitzgerald.

A spokesperson for federal Health Minister Leona Aglukkaq said Massachusetts-based isotopes supplier Lantheus Medical Imaging has assured the government it can manage the increased demand for the alternative isotope.

“Lantheus, which we understand is the major provider of thallium in Canada, informs us that they are able to handle the increased orders from clients for thallium during the shortage,” press secretary Josée Bellemare wrote in an email.

There is no end in sight to the shortage of technetium-99 — a decay product of the molybdenum-99 isotope produced at the Chalk River reactor.

OÂ’Brien said some hospitals would run out of isotopes by June 12 after being told they will not receive any isotope shipments from two nuclear reactors in the Netherlands and South Africa that have been helping to fill the gap.

“There was a time last week when both the South African reactor and the (Dutch) reactor were shut down around the same time and there was a supply disruption as a result of that,” said O’Brien.

Dawn-Marie King, clinical operations director for the joint medical imaging department at the University Health Network in Toronto, said her hospitals have enough isotopes for the week but face having to cancel procedures next week if they do not receive another generator on June 14.

“Up until now we have been very lucky and haven’t had to, but we’re just sort of going week by week at this point,” said King.

Canada Finalizes Clean Electricity Regulations for 2050

Canada Clean Electricity Regulations align climate policy with grid reliability, scaling renewables, energy storage, and low-carbon power to reach net-zero by 2050 while maintaining affordability through federal incentives, provincial flexibility, and investment.

 

Key Points

Nationwide rules to decarbonize power by 2050, capping emissions and protecting grid reliability and affordability.

✅ Net-zero electricity by 2050 with strict emissions limits

✅ Provincial flexibility and federal investments to cut costs

✅ Scales renewables, storage, and clean firm power for reliability

 

Canada's final Clean Electricity Regulations, unveiled in December 2024, alongside complementary provincial frameworks such as Ontario's clean electricity regulations that guide provincial implementation, represent a critical step toward ensuring a sustainable and reliable energy future. With electricity demand set to rise as the country’s population and economy grow, the Canadian government has put forward a robust plan that balances climate goals with the need for reliable, affordable power.

The regulations are designed to reduce greenhouse gas emissions from the electricity sector, which is already one of Canada's cleanest, with 85% of its electricity sourced from renewable energies like hydro, wind, and solar, and growing attention to clean grids and batteries nationwide. The target is to achieve net-zero emissions in electricity generation by 2050, a goal that will support the country’s broader climate ambitions.

One of the central goals of the Clean Electricity Regulations is to make sure that Canada’s power grid can accommodate future demand in light of a critical electrical supply crunch identified by analysts, while ensuring that emissions are cut effectively. The regulations set strict pollution limits but allow flexibility for provinces and territories to meet these goals in ways that suit their local circumstances. This approach recognizes the diverse energy resources across Canada, from the large-scale hydroelectric capacity in Quebec to the growing wind and solar projects in the West.

A key benefit of these regulations is the assurance that they will not result in higher electricity rates for most Canadians. In fact, according to government analyses, and resources like the online CER bill tool that explain how fees and usage affect charges, the regulations are expected to have a neutral or even slightly positive impact on electricity costs. This is due in part to significant federal investments in the electricity sector, totaling over $60 billion. These investments are intended to support the transition to clean electricity while minimizing costs for consumers.

The shift to clean electricity is also expected to generate significant savings for Canadian households. As energy prices continue to fluctuate, clean electricity, especially from renewable sources, is becoming more cost-competitive compared to fossil fuels. Over the next decade, this transition is expected to result in $15 billion in total savings for Canadians, with 84% of households projected to benefit from lower energy bills. The savings are a result of federal incentives aimed at encouraging the adoption of efficient electric appliances, vehicles, and heating systems.

Moreover, reducing emissions from the electricity sector will play a major role in cutting Canada’s overall greenhouse gas pollution. By 2050, it’s estimated that these regulations will reduce nearly 181 megatonnes of emissions, which is equivalent to removing over 55 million cars from the road. This is a crucial step in meeting Canada’s climate targets and mitigating the impacts of climate change, such as extreme weather events, which have already led to significant economic losses.

The economic benefits extend beyond savings on energy bills. The regulations and the broader clean electricity strategy will create substantial job opportunities. The clean energy sector, which includes jobs in wind, solar, and nuclear power, is poised for massive growth, and provinces like Alberta have outlined a path to clean electricity to support that momentum. It’s estimated that by 2030, the transition to clean electricity could create 400,000 new jobs, with further job growth projected for the years to come. These jobs are expected to include roles in both the construction and operation of new energy infrastructure, many of which will be unionized positions offering good wages and benefits.

To help meet the rising demand for clean energy, the government’s strategy emphasizes technological innovation and the integration of new energy sources, including market design updates such as proposed market changes that can enable investment. Renewable energy technologies such as wind and solar power have become increasingly cost-competitive, and their continued development is expected to reduce the overall cost of electricity generation. The regulations also encourage the adoption of energy storage solutions, which are essential for managing the intermittent nature of renewable energy sources.

In addition to the environmental and economic benefits, the Clean Electricity Regulations will help improve public health. Air pollution from fossil fuel power generation is a major contributor to respiratory illnesses and other health issues. By transitioning to clean energy sources, Canada can reduce harmful air pollutants, leading to better health outcomes and a lower burden on the healthcare system.

As Canada moves toward a net-zero electricity grid, including the federal 2035 target that some have criticized as changing goalposts in Saskatchewan, the Clean Electricity Regulations represent a comprehensive and flexible approach to managing the energy transition. With significant investments in clean energy technologies and the adoption of policies that ensure affordable electricity for all Canadians, the government is setting the stage for a cleaner, more sustainable future. These efforts will not only help Canada meet its climate goals but also create a thriving clean energy economy that benefits workers, businesses, and families across the country.

Two new electricity interconnectors planned for UK

Ofgem UK Electricity Interconnectors will channel subsea cables, linking Europe, enabling energy import/export, integrating offshore wind via multiple-purpose interconnectors, boosting grid stability, capacity, and investment under National Grid analysis to 2030 targets.

 

Key Points

Subsea links between the UK and Europe that trade power, integrate offshore wind, and reinforce grid capacity.

✅ Two new subsea interconnector bids open in 2025

✅ Pilot for multiple-purpose links to offshore wind clusters

✅ National Grid to assess optimal routes, capacity, and locations

 

Ofgem has opened bids to build two electricity interconnectors between the UK and continental Europe as part of the broader UK grid transformation now underway.

The energy regulator said this would “bring forward billions of pounds of investment” in the subsea cables, such as the Lake Erie Connector, which can import cheaper energy when needed and export surplus power from the UK when it is available.

Developers will be invited to submit bids to build the interconnectors next year. Ofgem will additionally run a pilot scheme for ‘multiple-purpose interconnectors’, which are used to link clusters of offshore wind farms and related innovations like an offshore vessel chargepoint to an interconnector.

This forms part of the UK Government drive to more than double capacity by 2030, and to manage rising electric-vehicle demand, as discussed in EV grid impacts, in support of its target of quadrupling offshore wind capacity by the same date.

Interconnectors provide some 7 per cent of UK electricity demand. The UK so far has seven electricity interconnectors linked to Ireland, France, Belgium, the Netherlands and Norway, while projects like the Ireland-France connection illustrate broader European grid integration.

Balfour Beatty won a £90m contract for onshore civil engineering works on the Viking Link Norway interconnector, which is due to come into operation in 2023, while London Gateway's all-electric berth highlights related port electrification.

It said that interconnector developers have in the past been allowed to propose their preferred design, connection location and sea route to the connecting country. Ofgem has now said it may decide to consider only those projects that meet its requirements based on an analysis of location and capacity needs by National Grid.

Ofgem has not specified that the new interconnectors must link to any specific place or country, but may do so later, as priorities like the Cyprus electricity highway illustrate emerging directions.

British carbon tax leads to 93% drop in coal-fired electricity

Carbon Price Support, the UK carbon tax on power, slashed coal generation, cut CO2 emissions, boosted gas and imports via interconnectors, and signaled effective electricity market decarbonization across Great Britain and the EU.

 

Key Points

A UK power-sector carbon tax that drove coal off the grid, cut emissions, and shifted generation toward gas and imports.

✅ Coal generation fell from 40% to 3% in six years

✅ Rate rose to £18/tCO2 in 2015, boosting the coal-to-gas switch

✅ Added ~£39 to 2018 bills; imports via interconnectors eased prices

 

A tax on carbon dioxide emissions in Great Britain, introduced in 2013, has led to the proportion of electricity generated from coal falling from 40% to 3% over six years, a trend mirrored by global coal decline in power generation, according to research led by UCL.

British electricity generated from coal fell from 13.1 TWh (terawatt hours) in 2013 to 0.97 TWh in September 2019, and was replaced by other less emission-heavy forms of generation such as gas, as producers move away from coal in many markets. The decline in coal generation accelerated substantially after the tax was increased in 2015.

In the report, 'The Value of International Electricity Trading', researchers from UCL and the University of Cambridge also showed that the tax—called Carbon Price Support—added on average £39 to British household electricity bills, within the broader context of UK net zero policies shaping the energy transition, collecting around £740m for the Treasury, in 2018.

Academics researched how the tax affected electricity flows to connected countries and interconnector (the large cables connecting the countries) revenue between 2015—when the tax was increased to £18 per tonne of carbon dioxide—and 2018. Following this increase, the share of coal-fired electricity generation fell from 28% in 2015 to 5% in 2018, reaching 3% by September 2019. Increased electricity imports from the continent, alongside the EU electricity demand outlook across member states, reduced the price impact in the UK, and meant that some of the cost was paid through a slight increase in continental electricity prices (mainly in France and the Netherlands).

Project lead Dr. Giorgio Castagneto Gissey (Bartlett Institute for Sustainable Resources, UCL) said: "Should EU countries also adopt a high carbon tax we would likely see huge carbon emission reductions throughout the Continent, as we've seen in Great Britain over the last few years."

Lead author, Professor David Newbery (University of Cambridge), said: "The Carbon Price Support provides a clear signal to our neighbours of its efficacy at reducing CO2 emissions."

The Carbon Price Support was introduced in England, Scotland and Wales at a rate of £4.94 per tonne of carbon dioxide-equivalent and is now capped at £18 until 2021.The tax is one part of the Total Carbon Price, which also includes the price of EU Emissions Trading System permits and reflects global CO2 emissions trends shaping policy design.

Report co-author Bowei Guo (University of Cambridge) said: "The Carbon Price Support has been instrumental in driving coal off the grid, but we show how it also creates distortions to cross-border trade, making a case for EU-wide adoption."

Professor Michael Grubb (Bartlett Institute for Sustainable Resources, UCL) said: "Great Britain's electricity transition is a monumental achievement of global interest, and has also demonstrated the power of an effective carbon price in lowering dependence on electricity generated from coal."

The overall report on electricity trading also covers the value of EU interconnectors to Great Britain, measures the efficiency of cross-border electricity trading and considers the value of post-Brexit decoupling from EU electricity markets, setting these findings against the global energy transition underway.

Published today, the report annex focusing on the Carbon Price Support was produced by UCL to focus on the impact of the tax on British energy bills, with comparisons to Canadian climate policy debates informing grid impacts.

Lawmakers push bill to connect Texas grid to rest of the nation

Connect the Grid Act links ERCOT to neighboring grids via high-voltage interconnections, enhancing reliability, resilience, and renewables integration. It enables power imports and exports with SPP, MISO, and the Western Interconnection under FERC oversight.

 

Key Points

A plan to link ERCOT with neighboring grids, improving reliability, enabling energy trade, and integrating renewables.

✅ High-voltage ties with SPP, MISO, and the Western Interconnection

✅ Enables imports during crises and exports of surplus power

✅ Brings ERCOT under FERC oversight; DoE to study Mexico links

 

In the aftermath of the devastating 2021 Texas blackouts, which exposed the vulnerabilities of the state's energy infrastructure, a significant legislative effort is underway to transform Texas from an energy island into a connected component of the broader U.S. power grid. Spearheaded by U.S. Representative Greg Casar, D-Austin, the proposed Connect the Grid Act is part of a push for smarter electricity infrastructure that seeks to remedy the isolation of the Electric Reliability Council of Texas (ERCOT) from neighboring power grids, a condition that significantly contributed to the crisis during Winter Storm Uri.

The blackouts, which left millions without power and resulted in significant loss of life and economic damage, underscored the inherent risks of Texas's unique energy infrastructure. Unlike the rest of the continental U.S., Texas's grid operates independently, limiting its ability to import electricity during emergencies. This isolation was a critical factor in the state's inability to respond effectively to the increased demand for power during the storm.

Recognizing the urgent need for a more resilient and integrated energy system, Rep. Casar's legislation aims to establish high-voltage connections between ERCOT and adjacent grid-operating organizations, including the Southern Power Pool, MISO, and the Western Interconnection. This would not only improve the reliability of Texas's power supply by enabling energy imports during crises but also allow the state to export surplus energy, thereby enhancing the economic efficiency and sustainability of its energy market.

The Connect the Grid Act proposes a range for the new connections' transfer capabilities, aiming to significantly boost the amount of power that can be shared between Texas and its neighbors. Such interconnectivity is anticipated to reduce energy costs for consumers by mitigating scarcity and enabling access to Texas's vast renewable energy resources, even as grid modernization affordability remains a point of debate among stakeholders. However, the bill faces opposition due to concerns over federal oversight, as it would bring ERCOT under the jurisdiction of the Federal Energy Regulatory Commission (FERC).

Some analysts note that policies such as later school start dates can ease late-summer peak demand as well.

At a press conference held at the IBEW Local 520 headquarters, Rep. Casar, along with environmental groups, labor unions, and frontline workers, highlighted the benefits of the proposed legislation. The bill also includes provisions for a Department of Energy study on the potential benefits of interconnecting with Mexico, and parallels proposals for macrogrids in Canada that seek greater reliability across borders.

The Connect the Grid Act reflects a broader national trend towards increasing the interconnectivity of regional power grids, a move deemed essential for the transition to renewable energy and combating climate change risks to the U.S. grid through expanded interconnection. By enabling the flow of clean energy from renewable-rich areas like Texas to energy-hungry urban centers, the legislation supports a more sustainable and resilient national energy infrastructure.

Critics of Texas's grid independence, including energy experts and federal regulators, have long advocated for such interconnections. They argue that increased access to neighboring grids could have mitigated the effects of the 2021 blackouts and emphasize the importance of a grid that can withstand extreme weather events. The Federal Energy Regulatory Commission and the North American Electric Reliability Corp. have both explored mandates and studies to promote electricity transfer between regional grids, while states like California grid upgrades are investing to modernize networks as well, highlighting the national importance of grid interconnectivity.

Despite the potential challenges of increased federal regulation, proponents of the Connect the Grid Act argue that the benefits of interconnection far outweigh the drawbacks. By reducing energy costs, enhancing grid reliability, and promoting renewable energy, the legislation aims to secure a more sustainable and equitable energy future for Texas and the nation.

If passed, the Connect the Grid Act would mark a historic shift in Texas's energy policy, ending the state's long-standing isolation and positioning it as a key player in the national and potentially international energy landscape, and echoes calls for a western Canadian electricity grid to strengthen regional ties. The bill sets a completion deadline of January 1, 2035, for the construction of the new connections, with other projects, like the one by Pattern Energy, potentially connecting ERCOT to parts of the Southeastern grid even earlier, by 2029. This legislative effort represents a critical step towards ensuring that Texas can meet its energy needs reliably and sustainably, while also contributing to the broader goal of transitioning to a cleaner, more resilient power system.

Does Providing Electricity To The Poor Reduce Poverty? Maybe Not

Rural Electrification Poverty Impact examines energy access, grid connections, and reliability, testing economic development claims via randomized trials; findings show minimal gains without appliances, reliable supply, and complementary services like education and job creation initiatives.

 

Key Points

Study of household grid connections showing modest poverty impact without reliable power and appliances.

✅ Randomized grid connections showed no short-term income gains.

✅ Low reliability and few appliances limited electricity use.

✅ Complementary investments in jobs, education, health may be needed.

 

The head of Swedfund, the development finance group, recently summarized a widely-held belief: “Access to reliable electricity drives development and is essential for job creation, women’s empowerment and combating poverty.” This view has been the driving force behind a number of efforts to provide electricity to the 1.1 billion people around the world living in energy poverty, such as India's village electrification initiatives in recent years.

But does electricity really help lift households out of poverty? My co-authors and I set out to answer this question. We designed an experiment in which we first identified a sample of “under grid” households in Western Kenya—structures that were located close to but not connected to a grid. These households were then randomly divided into treatment and control groups. In the treatment group, we worked closely with the rural electrification agency to connect the households to the grid for free or at various discounts. In the control group, we made no changes. After eighteen months, we surveyed people from both groups and collected data on an assortment of outcomes, including whether they were employed outside of subsistence agriculture (the most common type of work in the region) and how many assets they owned. We even gave children basic tests, as a frequent assertion is that electricity helps children perform better in school since they are able to study at night.

When we analyzed the data, we found no differences between the treatment and control groups. The rural electrification agency had spent more than $1,000 to connect each household. Yet eighteen months later, the households we connected seemed to be no better off. Even the children’s test scores were more or less the same. The results of our experiment were discouraging, and at odds with the popular view that supplying households with access to electricity will drive economic development. Lifting people out of poverty may require a more comprehensive approach to ensure that electricity is not only affordable (with some evidence that EV growth can benefit all customers in mature markets), but is also reliable, useable, and available to the whole community, paired with other important investments.

For instance, in many low-income countries, the grid has frequent blackouts and maintenance problems, making electricity unreliable, as seen in Nigeria's electricity crisis in recent years. Even if the grid were reliable, poor households may not be able to afford the appliances that would allow for more than just lighting and cell phone charging. In our data, households barely bought any appliances and they used just 3 kilowatt-hours per month. Compare that to the U.S. average of 900 kilowatt-hours per month, a figure that could rise as EV adoption increases electricity demand over time.

There are also other factors to consider. After all, correlation does not equal causation. There is no doubt that the 1.1 billion people without power are the world’s poorest citizens. But this is not the only challenge they face. The poor may also lack running water, basic sanitation, consistent food supplies, quality education, sufficient health care, political influence, and a host of other factors that may be harder to measure but are no less important to well-being. Prioritizing investments in some of these other factors may lead to higher immediate returns. Previous work by one of my co-authors, for example, shows substantial economic gains from government spending on treatment for intestinal worms in children.

It’s possible that our results don’t generalize. They certainly don’t apply to enhancing electricity services for non-residential customers, like factories, hospitals, and schools, and electric utilities adapting to new load patterns. Perhaps the households we studied in Western Kenya are particularly poor (although measures of well-being suggest they are comparable to rural households across Sub-Saharan Africa) or politically disenfranchised. Perhaps if we had waited longer, or if we had electrified an entire region, the household impacts we measured would have been much greater. But others who have studied this question have found similar results. One study, also conducted in Western Kenya, found that subsidizing solar lamps helped families save on kerosene, but did not lead children to study more. Another study found that installing solar-powered microgrids in Indian villages resulted in no socioeconomic benefits.

Romania moves to terminate talks with Chinese partner in nuke project

Romania Ends CGN Cernavoda Nuclear Deal, as Nuclearelectrica moves to terminate negotiations on reactors 3 and 4, citing the EU Green Deal, US partnership, NATO, and a shift to alternative nuclear capacity options.

 

Key Points

Romania orders Nuclearelectrica to end CGN talks on Cernavoda units 3-4 and pursue alternative nuclear options.

✅ Negotiations on Cernavoda units 3-4 to be formally terminated

✅ EU Green Deal and US partnership cited over security concerns

✅ Board to draft strategies for new domestic nuclear capacity

 

Romania's government has mandated the managing board of local nuclear power producer Nuclearelectrica to initiate procedures for terminating negotiations with China General Nuclear Power Group (CGN) on building two new reactors at the Cernavoda nuclear power plant, where IAEA safety reports continue to shape operations.

The government also mandated the managing board to analyse and draw up strategic options on the construction of new electricity generation capacities from nuclear sources, as other countries such as India take steps to get nuclear back on track in response to demand.

The company will negotiate the termination of the agreement signed in 2015 for developing and operating units 3 and 4 at Cernavoda, even as Germany turns away from nuclear within the European landscape. 

At the end of last month, Economy Minister Virgil Popescu said that the collaboration with the Chinese company couldn't continue as it has yielded no results in seven years, despite China's nuclear program expanding steadily elsewhere.

"We have a strategic partnership with the US, and we hold on to it, we respect our partners. We are members of the EU and Nato, even as Germany's final reactor closures unfold in Europe. Aside from that, I think that seven years since this collaboration with the Chinese company began is enough to realise that we can't move on," Popescu said at that time.

Liberal Prime Minister Ludovic Orban announced in January that the government would exit the deal with its Chinese partner. He invoked the European Union's Green Deal rather than security issues or cost concerns circulated previously as the main reason behind a potential end of the deal with CGN to expand Romania's only nuclear power plant, amid concerns that Europe is losing nuclear power when it needs energy.

In August last year, the US included CGN on a blacklist for allegedly trying to get nuclear technology from the US to be used for military purposes in China, even as nuclear cooperation with Cambodia expands in the region.
