Chalk River reactor returns to service

Manitoba-Minnesota Transmission Project faces NEB certificate review, with public hearings, Indigenous consultation, and cross-border approval weighing permit vs certificate timelines, potential land expropriation, and Hydro's 2020 in-service date for the 308-MW intertie.

Key Points

A cross-border hydro line linking Manitoba and Minnesota, now under NEB review through a permit or certificate process.

✅ NEB recommends certificate with public hearings and cabinet approval

✅ Stakeholders cite land, health, and economic impacts along route

✅ Hydro targets May-June 2020 in-service despite review

A recommendation from the National Energy Board could push back the construction start date of a $453-million hydroelectric transmission line from Manitoba to Minnesota.

In a letter to federal Natural Resources Minister Jim Carr, the regulatory agency recommends using a "certificate" approval process, which could take more time than the simpler "permit" process Manitoba Hydro favours.

The certificate process involves public hearings, reflecting First Nations intervention seen in other power-line debates, to weigh the merits of the project, which would then go to the federal cabinet for approval.

The NEB says this process would allow for more procedural flexibility and "address Aboriginal concerns that may arise in the circumstances of this process."

The Manitoba-Minnesota Transmission Project would provide the final link in a chain that brings hydroelectricity from generating stations in northern Manitoba, through the Bipole III transmission line and, like the New England Clean Power Link project, across the U.S. border as part of a 308-megawatt deal with the Green Bay-based Wisconsin Public Service.

When Hydro filed its application in December 2016, it had expected to have approval by the end of August 2017 and to begin construction on the line in mid-December, in order to have the line in operation by May or June 2020.  

Groups representing stakeholders along the proposed route of the transmission line had mixed reactions to the energy board's recommendation.

A lawyer representing a coalition of more than 120 landowners in the Rural Municipality of Taché and around La Broquerie, Man., welcomed the opportunity to have a more "fulsome" discussion about the project.

"I think it's a positive step. As people become more familiar with the project, the deficiencies with it become more obvious," said Kevin Toyne, who represents the Southeast Stakeholders Coalition.

Toyne said some coalition members are worried that Hydro will forcibly expropriate land in order to build the line, while others are worried about potential economic and health impacts of having the line so close to their homes. They have proposed moving the line farther east.

When the Clean Environment Commission — an arm's-length provincial government agency — held public hearings on the proposed route earlier this year, the coalition brought their concerns forward, echoing Site C opposition voiced by northerners, but Toyne says both the commission and Hydro ignored them.

Hydro still aiming for 2020 in-service date

The Manitoba Métis Federation also participated in those public hearings. MMF president David Chartrand worries about the impact a possible delay, as seen with the Site C work halt tied to treaty rights, could have on revenue from sales of hydroelectric power to the U.S.

"I know that a lot of money, billions have been invested on this line. And if the connection line is not done, then of course this will be sitting here, not gaining any revenue, which will affect every Métis in this province, given our Hydro bill's going to go up," Chartrand said.The NEB letter to Minister Carr requests that he "determine this matter in an expedited manner."

Manitoba Hydro spokesperson Bruce Owen said in an email that the Crown corporation will participate in whatever process, permit or certificate, the NEB takes.

"Manitoba Hydro does not have any information at this point in time that would change the estimated in-service date (May-June 2020) for the Manitoba-Minnesota Transmission Project," he said.

The federal government "is currently reviewing the NEB's recommendation to designate the project as subject to a certificate, which would result in public hearings," said Alexandre Deslongchamps, a spokesperson for Carr.

"Under the National Energy Board Act, an international power line requires either the approval by the NEB through a permit or approval by the Government of Canada by a certificate. Both must be issued by the NEB," he wrote in an email to CBC News.

By law, the certificate process is not to take longer than 15 months.

Rising Greenhouse Gas Concentrations drive climate change, with CO2, methane, and nitrous oxide surging; WMO data show higher radiative forcing, elevated pre-industrial baselines, and persistent atmospheric concentrations despite Paris Agreement emissions pledges.

Key Points

Increasing atmospheric CO2, methane, and nitrous oxide levels that raise radiative forcing and drive warming.

✅ WMO data show CO2 at 407.8 ppm in 2018, above decade average

✅ Methane and nitrous oxide surged, elevating total radiative forcing

✅ Concentrations differ from emissions; sinks absorb about half

The World Meteorological Organization (WMO) says the increase in CO2 was just above the average rise recorded over the last decade.

Levels of other warming gases, such as methane and nitrous oxide, have also surged by above average amounts.

Since 1990 there's been an increase of 43% in the warming effect on the climate of long lived greenhouse gases.

The WMO report looks at concentrations of warming gases in the atmosphere rather than just emissions.

The difference between the two is that emissions refer to the amount of gases that go up into the atmosphere from the use of fossil fuels, such as burning coal for coal-fired electricity generation and from deforestation.

Concentrations are what's left in the air after a complex series of interactions between the atmosphere, the oceans, the forests and the land. About a quarter of all carbon emissions are absorbed by the seas, and a similar amount by land and trees, while technologies like carbon capture are being explored to remove CO2.

Using data from monitoring stations in the Arctic and all over the world, researchers say that in 2018 concentrations of CO2 reached 407.8 parts per million (ppm), up from 405.5ppm a year previously.

This increase was above the average for the last 10 years and is 147% of the "pre-industrial" level in 1750.

The WMO also records concentrations of other warming gases, including methane and nitrous oxide, and some countries have reported declines in certain potent gases, as noted in US greenhouse gas controls reports, though global levels remain elevated. About 40% of the methane emitted into the air comes from natural sources, such as wetlands, with 60% from human activities, including cattle farming, rice cultivation and landfill dumps.

Methane is now at 259% of the pre-industrial level and the increase seen over the past year was higher than both the previous annual rate and the average over the past 10 years.

Nitrous oxide is emitted from natural and human sources, including from the oceans and from fertiliser-use in farming. According to the WMO, it is now at 123% of the levels that existed in 1750.

Last year's increase in concentrations of the gas, which can also harm the ozone layer, was bigger than the previous 12 months and higher than the average of the past decade.

What concerns scientists is the overall warming impact of all these increasing concentrations. Known as total radiative forcing, this effect has increased by 43% since 1990, and is not showing any indication of stopping.

There is no sign of a slowdown, let alone a decline, in greenhouse gases concentration in the atmosphere despite all the commitments under the Paris agreement on climate change and the ongoing global energy transition efforts," said WMO Secretary-General Petteri Taalas.

"We need to translate the commitments into action and increase the level of ambition for the sake of the future welfare of mankind," he added.

"It is worth recalling that the last time the Earth experienced a comparable concentration of CO2 was three to five million years ago. Back then, the temperature was 2-3C warmer, sea level was 10-20m higher than now," said Mr Taalas.

The UN Environment Programme will report shortly on the gap between what actions countries are taking to cut carbon, for example where Australia's emissions rose 2% recently, and what needs to be done to keep under the temperature targets agreed in the Paris climate pact.

Preliminary findings from this study, published during the UN Secretary General's special climate summit last September, indicated that emissions continued to rise during 2018, although global emissions flatlined in 2019 according to the IEA.

Both reports will help inform delegates from almost 200 countries who will meet in Madrid next week for COP25, following COP24 in Katowice the previous year, the annual round of international climate talks.

Manitoba Crypto Mining Electricity Pause signals a moratorium to manage grid strain, Manitoba Hydro capacity, infrastructure costs, and electricity rates, while policymakers evaluate sustainable energy demand, and planning for data centers and blockchain operations.

Key Points

A temporary halt on mining power hookups in Manitoba to assess grid impacts, protect rates, and plan sustainable use.

✅ Applies only to new service requests; existing sites unaffected

✅ Addresses grid strain, infrastructure costs, electricity rates

✅ Enables review with Manitoba Hydro for sustainable policy

The Manitoba government has temporarily suspended approving new electricity service connections for cryptocurrency mining operations, a step similar to BC Hydro's suspension seen in a neighboring province.

The Original Pause

The pause was initially imposed in November 2022 due to concerns that the rapid influx of cryptocurrency mining operations could place significant strain on the province's electrical grid. Manitoba Hydro, the province's primary electric utility, which has also faced legal scrutiny in the Sycamore Energy lawsuit, warned that unregulated expansion of the industry could necessitate billions of dollars in infrastructure investments, potentially driving up electricity rates for Manitobans.

The Extended Pause Offers Time for Review

The extension of the pause is meant to provide the government and Manitoba Hydro with more time to assess the situation thoroughly and develop a long-term solution addressing the challenges and opportunities presented by cryptocurrency mining, including evaluating emerging options such as modular nuclear reactors that other jurisdictions are studying. The government has stated its commitment to ensuring that the long-term impacts of the industry are understood and don't unintentionally harm other electricity customers.

What Does the Pause Mean?

The pause does not affect existing cryptocurrency operations but prevents the establishment of new ones.  It applies specifically to requests for electricity service that haven't yet resulted in agreements to construct infrastructure or supply electricity, and it comes amid regional policy shifts like Alberta ending its renewable moratorium that also affect grid planning.

Concerns About Energy Demands

Cryptocurrency mining involves running high-powered computers around the clock to solve complex mathematical problems. This process is incredibly energy-intensive. Globally, the energy consumption of cryptocurrency networks has drawn scrutiny for its environmental impact, with examples such as Iceland's mining power use illustrating the scale. In Manitoba, concern focuses on potentially straining the electrical grid and making it difficult for Manitoba Hydro to plan for future growth.

Other Jurisdictions Taking Similar Steps

Manitoba is not alone in its cautionary approach to cryptocurrency mining. Several other regions and utilities have implemented restrictions or are exploring limitations on how cryptocurrency miners can access electricity, including moves by Russia to ban mining amid power deficits. This reflects a growing awareness among policymakers about the potentially destabilizing impact this industry could have on power grids and electricity markets.

Finding a Sustainable Path Forward

Manitoba Hydro has stated that it is open to working with cryptocurrency operations but emphasizes the need to do so in a way that protects existing ratepayers and ensures a stable and reliable electricity system for all Manitobans, while recognizing market uncertainties highlighted by Alberta wind project challenges in a neighboring province. The government's extension of the pause signifies its intention to find a responsible path forward, balancing the potential for economic development with the necessity of safeguarding the province's power supply.

2019 Global CO2 Emissions stayed flat, IEA reports, as renewable energy growth, wind and solar deployment, nuclear output, and coal-to-gas switching in advanced economies offset increases elsewhere, supporting climate goals and clean energy transitions.

Key Points

33 gigatonnes, unchanged YoY, as advanced economies cut power emissions via renewables, gas, and nuclear.

✅ IEA reports emissions flat at 33 Gt despite 2.9% GDP growth

✅ Advanced economies cut power-sector CO2 via wind, solar, gas

✅ Nuclear restarts and mild weather aided reductions

Despite widespread expectations of another increase, global energy-related CO2 emissions stopped growing in 2019, according to International Energy Agency (IEA) data released today. After two years of growth, global emissions were unchanged at 33 gigatonnes in 2019, a notable marker in the global energy transition narrative even as the world economy expanded by 2.9%.

This was primarily due to declining emissions from electricity generation in advanced economies, thanks to the expanding role of renewable sources (mainly wind and solar across many markets), fuel switching from coal to natural gas, and higher nuclear power generation, the Paris-based organisation says in the report.

"We now need to work hard to make sure that 2019 is remembered as a definitive peak in global emissions, not just another pause in growth," said Fatih Birol, the IEA's executive director. "We have the energy technologies to do this, and we have to make use of them all."

Higher nuclear power generation in advanced economies, particularly in Japan and South Korea, avoided over 50 Mt of CO2 emissions. Other factors included milder weather in several countries, and slower economic growth in some emerging markets. In China, emissions rose but were tempered by slower economic growth and higher output from low-carbon sources of electricity. Renewables continued to expand in China, and 2019 was also the first full year of operation for seven large-scale nuclear reactors in the country.

A significant decrease in emissions in advanced economies in 2019 offset continued growth elsewhere. The USA recorded the largest emissions decline on a country basis, with a fall of 140 million tonnes, or 2.9%. US emissions are now down by almost 1 gigatonne from their peak in 2000. Emissions in the European Union fell by 160 million tonnes, or 5%, in 2019 driven by reductions in the power sector as electricity producers move away from coal in the generation mix. Japan’s emissions fell by 45 million tonnes, or around 4%, the fastest pace of decline since 2009, as output from recently restarted nuclear reactors increased.

Emissions in the rest of the world grew by close to 400 million tonnes in 2019, with almost 80% of the increase coming from countries in Asia where coal-fired power generation continued to rise, and in Australia emissions rose 2% due to electricity and transport. Coal-fired power generation in advanced economies declined by nearly 15%, reflecting a sharp fall in coal-fired electricity across multiple markets, as a result of growth in renewables, coal-to-gas switching, a rise in nuclear power and weaker electricity demand.

The IEA will publish a World Energy Outlook Special Report in June that will map out how to cut global energy-related carbon emissions by one-third by 2030 and put the world on track for longer-term climate goals, a pathway that, in Canada, will require more electricity to hit net-zero. It will also hold an IEA Clean Energy Transitions Summit in Paris on 9 July, bringing together key government ministers, CEOs, investors and other major stakeholders.

Birol will discuss the results published today tomorrow at an IEA Speaker Series event at its headquarters with energy and climate ministers from Poland, which hosted COP24 in Katowice; Spain, which hosted COP25 in Madrid; and the UK, which will host COP26 in Glasgow this year, as greenhouse gas concentrations continue to break records worldwide.

NEIMA advances NRC regulatory modernization, creating a licensing framework for advanced reactors, improving uranium permitting, capping reactor fees, and mandating DOE planning for excess uranium, boosting transparency, accountability, and innovation across the US nuclear sector.

Key Points

NEIMA is a US law modernizing NRC rules and enabling advanced reactor licensing while reforming fees.

✅ Modernizes NRC licensing for advanced reactors

✅ Caps annual reactor fees and boosts transparency

✅ Streamlines uranium permitting; directs DOE plans

Bipartisan legislation modernising US nuclear regulation and supporting the establishment of a licensing framework for next-generation advanced reactors has been signed by US President Donald Trump, whose order boosting U.S. uranium and nuclear energy underscored the administration's focus on the sector.

The Nuclear Energy Innovation and Modernisation Act (NEIMA) became law on 14 January.

As well as directing the Nuclear Regulatory Commission (NRC) to modify the licensing process for commercial advanced nuclear reactor facilities, the bill establishes new transparency and accountability measures to the regulator's budget and fee programmes, and caps fees for existing reactors. It also directs the NRC to look at ways of improving the efficiency of uranium licensing, including investigating the safety and feasibility of extending uranium recovery licences from ten to 20 years' duration, and directs the Department of Energy, which oversees nuclear cleanup and related projects, to issue at least every ten years a long-term plan detailing the management of its excess uranium inventories.

Maria Korsnick, president and CEO of the US Nuclear Energy Institute, described NEIMA as a "significant, positive step" toward the reform of the NRC's fee collection process. "This legislation establishes a more equitable and transparent funding structure which will benefit all operating reactors and future licensees," she said. "The bill also reaffirms Congress’s support for nuclear innovation by working to establish an efficient and stable regulatory structure that is prepared to license the advanced reactors of the future."

Marilyn Kray, president-elect of the American Nuclear Society, said the passage of the legislation was a "big win" for the nation and its nuclear community. "By reforming outdated laws, NRC will now be able to invest more freely in advanced nuclear R&D and licensing activities. This in turn will accelerate deployment of cutting-edge American nuclear systems and better prepare the next generation of nuclear engineers and technologists," she said.

The bill was introduced in 2017 by Senator John Barrasso of Wyoming. It was approved by Congress on 21 December by 361 votes to 10, having been passed by the Senate the previous day, even as later Biden's climate law developments produced mixed results.

NEIMA is one of several bipartisan bills that support advanced nuclear innovation considered by the 115th US Congress, which ended on 2 January. These are: the Nuclear Energy Innovation Capabilities Act (NEICA); the Nuclear Energy Leadership Act; the Nuclear Utilisation of Keynote Energy Act; the Advanced Nuclear Fuel Availability Act, a focus sharpened by the U.S. ban on Russian uranium in the fuel market; and legislation to expedite so-called part 810 approvals, which are needed for the export of technology, equipment and components. NEICA, which supports the deployment of advanced reactors and also directs the DOE to develop a reactor-based fast neutron source for the testing of advanced reactor fuels and materials, was signed into law in October.

EV Decarbonization Strategy weighs life-cycle emissions and climate targets, highlighting mode shift to public transit, cycling, and walking, grid decarbonization, renewable energy, and charging infrastructure to cut greenhouse gases while reducing private car dependence.

Key Points

A plan to cut transport emissions by pairing EV adoption with mode shift, clean power, and less private car use.

✅ Prioritize mode shift: transit, cycling, and walking.

✅ Electrify remaining vehicles with clean, renewable power.

✅ Expand charging, improve batteries, and manage critical minerals.

California recently announced that it plans to ban the sales of gas-powered vehicles by 2035, a move similar to a 2035 electric vehicle mandate seen elsewhere, Ontario has invested $500 million in the production of electric vehicles (EVs) and Tesla is quickly becoming the world's highest-valued car company.

It almost seems like owning an electric vehicle is a silver bullet in the fight against climate change, but it isn't, as a U of T study explains today. What we should also be focused on is whether anyone should use a private vehicle at all.
 
As a researcher in sustainable mobility, I know this answer is unsatisfying. But this is where my latest research has led.

Battery EVs, such as the Tesla Model 3 - the best selling EV in Canada in 2020 - have no tailpipe emissions. But they do have higher production and manufacturing emissions than conventional vehicles, and often run on electricity that comes from fossil fuels.

Almost 18 per cent of the electricity generated in Canada came from fossil fuels in 2019, and even as Canada's EV goals grow more ambitious today, the grid mix varies from zero in Quebec to 90 per cent in Alberta.
 
Researchers like me compare the greenhouse gas emissions of an alternative vehicle, such as an EV, with those of a conventional vehicle over a vehicle lifetime, an exercise known as a life-cycle assessment. For example, a Tesla Model 3 compared with a Toyota Corolla can provide up to 75 per cent reduction in greenhouse gases emitted per kilometre travelled in Quebec, but no reductions in Alberta.

Hundreds of millions of new cars

To avoid extreme and irreversible impacts on ecosystems, communities and the overall global economy, we must keep the increase in global average temperatures to less than 2 C - and ideally 1.5 C - above pre-industrial levels by the year 2100.

We can translate these climate change targets into actionable plans. First, we estimate greenhouse gas emissions budgets using energy and climate models for each sector of the economy and for each country. Then we simulate future emissions, taking alternative technologies into account, as well as future potential economic and societal developments.

I looked at the U.S. passenger vehicle fleet, which adds up to about 260 million vehicles, while noting the potential for Canada-U.S. collaboration in this transition, to answer a simple question: Could the greenhouse gas emissions from the sector be brought in line with climate targets by replacing gasoline-powered vehicles with EVs?

The results were shocking. Assuming no changes to travel behaviours and a decarbonization of 80 per cent of electricity, meeting a 2 C target could require up to 300 million EVs, or 90 per cent of the projected U.S. fleet, by 2050. That would require all new purchased vehicles to be electric from 2035 onwards.

To put that into perspective, there are currently 880,000 EVs in the U.S., or 0.3 per cent of the fleet. Even the most optimistic projections, despite hype about an electric-car revolution gaining steam, from the International Energy Agency suggest that the U.S. fleet will only be at about 50 per cent electrified by 2050.

Massive and rapid electrification

Still, 90 per cent is theoretically possible, isn't it? Probably, but is it desirable?

In order to hit that target, we'd need to very rapidly overcome all the challenges associated with EV adoption, such as range anxiety, the higher purchase cost and availability of charging infrastructure.
 
A rapid pace of electrification would severely challenge the electricity infrastructure and the supply chain of many critical materials for the batteries, such as lithium, manganese and cobalt. It would require vast capacity of renewable energy sources and transmission lines, widespread charging infrastructure, a co-ordination between two historically distinct sectors (electricity and transportation systems) and rapid innovations in electric battery technologies. I am not saying it's impossible, but I believe it's unlikely.

Read more: There aren't enough batteries to electrify all cars - focus on trucks and buses instead

So what? Shall we give up, accept our collective fate and stop our efforts at electrification?

On the contrary, I think we should re-examine our priorities and dare to ask an even more critical question: Do we need that many vehicles on the road?

Buses, trains and bikes

Simply put, there are three ways to reduce greenhouse gas emissions from passenger transport: avoid the need to travel, shift the transportation modes or improve the technologies. EVs only tackle one side of the problem, the technological one.

And while EVs do decrease emissions compared with conventional vehicles, we should be comparing them to buses, including leading electric bus fleets in North America, trains and bikes. When we do, their potential to reduce greenhouse gas emissions disappears because of their life cycle emissions and the limited number of people they carry at one time.

If we truly want to solve our climate problems, we need to deploy EVs along with other measures, such as public transit and active mobility. This fact is critical, especially given the recent decreases in public transit ridership in the U.S., mostly due to increasing vehicle ownership, low gasoline prices and the advent of ride-hailing (Uber, Lyft)

Governments need to massively invest in public transit, cycling and walking infrastructure to make them larger, safer and more reliable, rather than expanding EV subsidies alone. And we need to reassess our transportation needs and priorities.

The road to decarbonization is long and winding. But if we are willing to get out of our cars and take a shortcut through the forest, we might get there a lot faster.
