Vale Ltd. announced a $49- million investment in a demonstration plant Friday that could be the next big thing in mining -- and cut the mining company's electricity costs in half.
The Copper Cliff Mine 114 Orebody Demonstration Plant will allow the company to test new and innovative mining technologies that could "dramatically improve mining processes across our operations," said Vale's Alex Henderson, general manager of mines and mill technology for the North Atlantic Region.
New technology developed in Sudbury by Rail-Veyor Technologies will be installed at the plant later this year. It will be the first underground application of the technology in North America.
The 114 Orebody Demonstration Plant is a new facility that will be built at the ore body in Copper Cliff, near Copper Cliff Mine and Clarabelle Mill, said Vale spokeswoman Angie Robson.
The purpose of the demonstration plant will be to "prove the technology" and prove that it can be applied underground, she said.
"It really could be the next big step change in mining and, from a safety, health and environment perspective, this really has some enormous benefits going forward."
Vale is estimating it could cut its energy consumption in half "because, as we go deeper, we require more ventilation. Right now, we use diesel equipment, which requires large drifts and requires a lot of ventilation to make sure the working environment is healthy," said Robson.
The Rail-Veyor system is essentially a small train. "It's electric so there is no diesel, there is no gas. From an energy reduction and carbon reduction point of view, it's very, very significant," said Robson.
The technology would also improve safety by reducing the risk of vehicle collision and increasing ground support.
"As you go deeper, the ground becomes more unstable and there's more ground support needed. With the Rail- Veyor, because it's quite literally like a small train, our drifts would have to be much smaller than they are now, so that would lend to increased ground support.
The Rail-Veyor would replace the large diesel equipment that Vale is using now.
Robson quotes Henderson as saying: "Right now, we bring the ore to the shaft, to then be brought up to surface. This would essentially bring the shaft to the ore.
"It's a much more efficient way of mining."
The system will lead to quicker development of ore bodies and make it profitable for Vale to mine ore bodies that might not have been economical before, "which is important for the ongoing sustainability" of Vale's operations, said Robson.
Mike Romaniuk is president and chief executive officer of Rail-Veyor Technologies in Sudbury.
At a news conference Friday, he said he looked forward to "advancing the commercialization of the technology in underground mines on a global basis."
Greater Sudbury Mayor Marianne Matichuk attended the news event, and said with projects such as Rail-Veyor, the city will continue to bring innovation and technology to new heights.
"Vale continues to be a key contributor to the mining industry, not only here at home, but around the world," said Matichuk. "Technology of this magnitude means sustainable income in a city where growing the job market is of the highest importance."
Robson said the project is expected to create about 100 jobs until it is complete in the first quarter of 2013.
The $49-million pricetag for the demonstration plant is part of the $3.4 billion in investments Vale will make in Sudbury operations in the next few years.
BCER Renewable Energy Permitting streamlines single-window approvals for wind, solar, and transmission projects in BC, cutting red tape, aligning with CleanBC, and accelerating investment, Indigenous partnerships, and low-carbon infrastructure growth provincewide.
Key Points
BC's single-window framework consolidates approvals for wind, solar, and transmission to accelerate energy projects.
✅ Single-window permits via BC Energy Regulator (BCER)
✅ Covers wind, solar, and high-voltage transmission lines
✅ Aligns with CleanBC, supports Indigenous partnerships
In a decisive move to bolster clean energy initiatives, the government of British Columbia (B.C.) has announced plans to overhaul the regulatory framework governing renewable energy projects. This initiative aims to expedite the development of wind, solar, and other renewable energy sources, positioning B.C. as a leader in sustainable energy production.
Transitioning Regulatory Authority to the BC Energy Regulator (BCER)
Central to this strategy is the proposed legislation, set to be introduced in spring 2025, which will transfer the permitting and regulatory oversight of renewable energy projects, aligning with offshore wind regulation plans at the federal level, from multiple agencies to the BC Energy Regulator (BCER). This transition is designed to create a "single-window" permitting process, simplifying approvals and reducing bureaucratic delays for developers.
Expanding BCER's Mandate
Historically known as the British Columbia Oil and Gas Commission, the BCER's mandate has evolved to encompass a broader range of energy projects. The upcoming legislation will empower the BCER to oversee renewable energy projects, including wind and solar, as well as high-voltage transmission lines like the North Coast Transmission Line (NCTL), in step with renewable transmission planning efforts elsewhere in North America. This expansion aims to streamline the regulatory process, providing developers with a single point of contact throughout the project lifecycle.
Economic and Environmental Implications
The restructuring is expected to unlock significant economic opportunities. Projections suggest that the streamlined process could attract between $5 billion and $6 billion in private investment and complement recent federal grid modernization funding initiatives, generating employment opportunities and fostering economic growth. Moreover, by facilitating the rapid deployment of renewable energy projects, B.C. aims to enhance its clean energy capacity, contributing to global sustainability goals.
Strengthening Partnerships with Indigenous Communities
A pivotal aspect of this initiative is the emphasis on collaboration with Indigenous communities. The government has highlighted the importance of engaging First Nations in the development process, ensuring that projects are not only environmentally sustainable but also socially responsible. This approach seeks to honor Indigenous rights and knowledge, fostering partnerships that benefit all stakeholders.
Supporting Infrastructure Development
The acceleration of renewable energy projects necessitates corresponding infrastructure enhancements. The NCTL, for instance, is crucial for meeting the increased electricity demand from sectors such as mining, port electrification, and hydrogen production, and for addressing regional grid constraints that limit renewable integration. By improving the transmission infrastructure, B.C. aims to support the growing energy needs of these industries while promoting clean energy solutions.
Aligning with CleanBC Objectives
This regulatory overhaul aligns seamlessly with B.C.'s CleanBC initiative, which sets ambitious targets for reducing greenhouse gas emissions and promoting energy efficiency, and supports Canada's goal of zero-emissions electricity by 2035 under active consideration. By removing regulatory barriers and expediting project approvals, the government aims to accelerate the transition to a low-carbon economy, positioning B.C. as a hub for clean energy innovation.
Addressing Potential Challenges
While the initiative has been lauded for its potential, experts caution that careful consideration must be given to environmental assessments and Indigenous consultation processes, as well as to lessons from Alberta's solar expansion challenges on land use and grid impacts. Ensuring that projects meet environmental standards and respect Indigenous rights is crucial for the long-term success and acceptance of renewable energy developments.
The proposed changes mark a significant shift in B.C.'s approach to energy development, reflecting a commitment to sustainability and economic growth. As the legislation moves through the legislative process, stakeholders across the energy sector are closely monitoring developments, particularly as Alberta ends its renewables moratorium and resumes project approvals across the Prairies, anticipating a more efficient and transparent regulatory environment that supports the rapid expansion of renewable energy projects.
B.C.'s plan to streamline the regulatory process for clean energy projects represents a bold step toward a sustainable and prosperous energy future. By consolidating regulatory authority under the BCER, fostering Indigenous partnerships, and aligning with broader environmental objectives, the province is setting a precedent for effective governance in the transition to renewable energy.
Canada Three-Layer Mask Recommendation advises non-medical masks with a polypropylene filter layer and tightly woven cotton, aligned with WHO guidance, to curb COVID-19 aerosols indoors through better fit, coverage, and public health compliance.
Key Points
PHAC advises three-layer non-medical masks with a polypropylene filter to improve indoor COVID-19 protection.
✅ Two fabric layers plus a non-woven polypropylene filter
✅ Ensure snug fit: cover nose, mouth, chin without gaps
✅ Aligns with WHO guidance for aerosols and droplets
The Public Health Agency of Canada is now recommending Canadians choose three-layer non-medical masks with a filter layer to prevent the spread of COVID-19, even as an IEA report projects higher electricity needs for net-zero, as they prepare to spend more time indoors over the winter.
Chief Public Health Officer Dr. Theresa Tam made the recommendation during her bi-weekly pandemic briefing in Ottawa Tuesday, as officials also track electricity grid security amid critical infrastructure concerns.
"To improve the level of protection that can be provided by non-medical masks or face coverings, we are recommending that you consider a three-layer nonmedical mask," she said.
Trust MedProtect For All Your Mask Protection

According to recently updated guidelines, two layers of the mask should be made of a tightly woven fabric, such as cotton or linen, and the middle layer should be a filter-type fabric, such as non-woven polypropylene fabric, as Canada explores post-COVID manufacturing capacity for PPE.
"We're not necessarily saying just throw out everything that you have," Tam told reporters, suggesting adding a filter can help with protection.
The Public Health website now includes instructions for making three-layer masks, while national goals like Canada's 2050 net-zero target continue to shape recovery efforts.
The World Health Organization has recommended three layers for non-medical masks since June, and experts note that cleaning up Canada's electricity is critical to broader climate resilience. When pressed about the sudden change for Canada, Tam said the research has evolved.
"This is an additional recommendation just to add another layer of protection. The science of masks has really accelerated during this particular pandemic. So we're just learning again as we go," she said.
"I do think that because it's winter, because we're all going inside, we're learning more about droplets and aerosols, and how indoor comfort systems from heating to air conditioning costs can influence behaviors."
She also urged Canadians to wear well-fitted masks that cover the nose, mouth and chin without gaping, as the federal government advances emissions and EV sales regulations alongside public health guidance.
France Nuclear Heatwave Restrictions signal reduced nuclear power along the Rhone River as EDF imposes output limits due to high water temperatures, grid needs, with minimal price impact amid strong solar and exports.
Key Points
Temporary EDF output limits at Rhone River reactors due to hot water, protecting ecosystems and grid reliability.
✅ EDF expects halved output at Bugey and Saint Alban.
✅ Cuts align with water temperature and discharge rules.
✅ Weekend midday curtailments offset by solar supply.
The high temperature warning has come early this year but will affect fewer nuclear power plants. High temperatures could halve nuclear power production, with river temperature limits at plants along France's Rhone River this week.
Output restrictions are expected at two nuclear plants in eastern France due to high temperature forecasts, nuclear operator EDF said. It comes several days ahead of a similar warning that was made last year but will affect fewer plants, and follows a period when power demand has held firm during lockdowns across Europe.
The hot weather is likely to halve the available power supply from the 3.6 GW Bugey plant from 13 July and the 2.6 GW Saint Alban plant from 16 July, the operator said.
However, production will be at least 1.8 GW at Bugey and 1.3 GW at Saint Alban to meet grid requirements, and may change according to grid needs, the operator said.
Kpler analyst Emeric de Vigan said the restrictions were likely to have little effect on output in practice. Cuts are likely only at the weekend or midday when solar output was at its peak so the impact on power prices would be slim.
He said the situation would need monitoring in the coming weeks, however, noting it was unusually early in the summer for nuclear-powered France to see such restrictions imposed.
Water temperatures at the Bugey plant already eclipsed the initial threshold for restrictions on 9 July, as European power hits records during the heatwave. They are currently forecast to peak next week and then drop again, Refinitiv data showed.
"France is currently net exporting large amounts of power – and, despite a nuclear power dispute with Germany, single nuclear units' supply restrictions will not have the same effect as last year," Refinitiv analyst Nathalie Gerl said.
The Garonne River in southern France has the highest potential for critical levels of warming, but its Golfech plant is currently offline for maintenance until mid-August, as Europe faces nuclear losses, the data showed.
"(The restrictions were) to be expected and it will probably occur more often," Greenpeace campaigner Roger Spautz said.
"The authorities must stick to existing regulations for water discharges. Otherwise, the ecosystems will be even more affected," he added.
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.
Texas Electricity Prices are shifting as deregulation matures, with competitive market shopping lowering residential rates, narrowing gaps with regulated areas, and EIA data showing long term declines versus national averages across most Texans.
Key Points
Texas Electricity Prices are average residential rates in deregulated and regulated markets across the state.
✅ Deregulated areas saw 17.4% residential price declines since 2006
✅ Regulated zones experienced a 5.5% increase over the same period
✅ Competitive shopping narrowed the gap; Texas averaged below US
Shopping for electricity is becoming cheaper for most Texans, according to a new study from the Texas Coalition for Affordable Power. But for those who live in an area with only one electricity provider, prices have increased in a recent 10-year period, the study says.
About 85 percent of Texans can purchase electricity from a number of providers in a deregulated marketplace, while the remaining 15 percent must buy power from a single provider, often an electric cooperative, in their area.
The report from the Texas Coalition for Affordable Power, which advocates for cities and local governments and negotiates their power contracts, pulls information from the U.S. Energy Information Administration to compare prices for Texans in the two models. Most Texans could begin choosing their electricity provider in 2002.
Buying power tends to be more expensive for Texans who live in a part of the state with a deregulated electricity market. But that gap is continuing to shrink as Texans become more willing to shop for power, even as electricity complaints have periodically risen. In 2015, the gap “was the smallest since the beginning of deregulation,” according to the report.
Between 2006 and 2015, the last year for which data is available, average residential electric prices for Texans in a competitive market decreased by 17.4 percent, while average prices increased by 5.5 percent in the regulated areas, even as the Texas power grid has periodically faced stress.
“These residential price declines are promising, and show the retail electric market is maturing,” Jay Doegey, executive director for the Texas Coalition for Affordable Power, said in a statement. “We’re encouraged by the price declines, but more progress is needed.”
The study attributes the decline to the prevalence of “low-priced individual deals” in the competitive areas, while policymakers consider market reforms to bolster reliability.
Overall, the average price of electricity in Texas (which produces and consumes the most electricity in the U.S.) — including the price in the deregulated marketplace, for the third time in four years — was below the national average in 2015.
ITER Nuclear Fusion advances tokamak magnetic confinement, heating deuterium-tritium plasma with superconducting magnets, targeting net energy gain, tritium breeding, and steam-turbine power, while complementing laser inertial confinement milestones for grid-scale electricity and 2025 startup goals.
Key Points
ITER Nuclear Fusion is a tokamak project confining D-T plasma with magnets to achieve net energy gain and clean power.
✅ Tokamak magnetic confinement with high-temp superconducting coils
✅ Deuterium-tritium fuel cycle with on-site tritium breeding
✅ Targets net energy gain and grid-scale, low-carbon electricity
It sounds like the stuff of dreams: a virtually limitless source of energy that doesn’t produce greenhouse gases or radioactive waste. That’s the promise of nuclear fusion, often described as the holy grail of clean energy by proponents, which for decades has been nothing more than a fantasy due to insurmountable technical challenges. But things are heating up in what has turned into a race to create what amounts to an artificial sun here on Earth, one that can provide power for our kettles, cars and light bulbs.
Today’s nuclear power plants create electricity through nuclear fission, in which atoms are split, with next-gen nuclear power exploring smaller, cheaper, safer designs that remain distinct from fusion. Nuclear fusion however, involves combining atomic nuclei to release energy. It’s the same reaction that’s taking place at the Sun’s core. But overcoming the natural repulsion between atomic nuclei and maintaining the right conditions for fusion to occur isn’t straightforward. And doing so in a way that produces more energy than the reaction consumes has been beyond the grasp of the finest minds in physics for decades.
But perhaps not for much longer. Some major technical challenges have been overcome in the past few years and governments around the world have been pouring money into fusion power research as part of a broader green industrial revolution under way in several regions. There are also over 20 private ventures in the UK, US, Europe, China and Australia vying to be the first to make fusion energy production a reality.
“People are saying, ‘If it really is the ultimate solution, let’s find out whether it works or not,’” says Dr Tim Luce, head of science and operation at the International Thermonuclear Experimental Reactor (ITER), being built in southeast France. ITER is the biggest throw of the fusion dice yet.
Its $22bn (£15.9bn) build cost is being met by the governments of two-thirds of the world’s population, including the EU, the US, China and Russia, at a time when Europe is losing nuclear power and needs energy, and when it’s fired up in 2025 it’ll be the world’s largest fusion reactor. If it works, ITER will transform fusion power from being the stuff of dreams into a viable energy source.
Constructing a nuclear fusion reactor ITER will be a tokamak reactor – thought to be the best hope for fusion power. Inside a tokamak, a gas, often a hydrogen isotope called deuterium, is subjected to intense heat and pressure, forcing electrons out of the atoms. This creates a plasma – a superheated, ionised gas – that has to be contained by intense magnetic fields.
The containment is vital, as no material on Earth could withstand the intense heat (100,000,000°C and above) that the plasma has to reach so that fusion can begin. It’s close to 10 times the heat at the Sun’s core, and temperatures like that are needed in a tokamak because the gravitational pressure within the Sun can’t be recreated.
When atomic nuclei do start to fuse, vast amounts of energy are released. While the experimental reactors currently in operation release that energy as heat, in a fusion reactor power plant, the heat would be used to produce steam that would drive turbines to generate electricity, even as some envision nuclear beyond electricity for industrial heat and fuels.
Tokamaks aren’t the only fusion reactors being tried. Another type of reactor uses lasers to heat and compress a hydrogen fuel to initiate fusion. In August 2021, one such device at the National Ignition Facility, at the Lawrence Livermore National Laboratory in California, generated 1.35 megajoules of energy. This record-breaking figure brings fusion power a step closer to net energy gain, but most hopes are still pinned on tokamak reactors rather than lasers.
In June 2021, China’s Experimental Advanced Superconducting Tokamak (EAST) reactor maintained a plasma for 101 seconds at 120,000,000°C. Before that, the record was 20 seconds. Ultimately, a fusion reactor would need to sustain the plasma indefinitely – or at least for eight-hour ‘pulses’ during periods of peak electricity demand.
A real game-changer for tokamaks has been the magnets used to produce the magnetic field. “We know how to make magnets that generate a very high magnetic field from copper or other kinds of metal, but you would pay a fortune for the electricity. It wouldn’t be a net energy gain from the plant,” says Luce.
One route for nuclear fusion is to use atoms of deuterium and tritium, both isotopes of hydrogen. They fuse under incredible heat and pressure, and the resulting products release energy as heat
The solution is to use high-temperature, superconducting magnets made from superconducting wire, or ‘tape’, that has no electrical resistance. These magnets can create intense magnetic fields and don’t lose energy as heat.
“High temperature superconductivity has been known about for 35 years. But the manufacturing capability to make tape in the lengths that would be required to make a reasonable fusion coil has just recently been developed,” says Luce. One of ITER’s magnets, the central solenoid, will produce a field of 13 tesla – 280,000 times Earth’s magnetic field.
The inner walls of ITER’s vacuum vessel, where the fusion will occur, will be lined with beryllium, a metal that won’t contaminate the plasma much if they touch. At the bottom is the divertor that will keep the temperature inside the reactor under control.
“The heat load on the divertor can be as large as in a rocket nozzle,” says Luce. “Rocket nozzles work because you can get into orbit within minutes and in space it’s really cold.” In a fusion reactor, a divertor would need to withstand this heat indefinitely and at ITER they’ll be testing one made out of tungsten.
Meanwhile, in the US, the National Spherical Torus Experiment – Upgrade (NSTX-U) fusion reactor will be fired up in the autumn of 2022, while efforts in advanced fission such as a mini-reactor design are also progressing. One of its priorities will be to see whether lining the reactor with lithium helps to keep the plasma stable.
Choosing a fuel Instead of just using deuterium as the fusion fuel, ITER will use deuterium mixed with tritium, another hydrogen isotope. The deuterium-tritium blend offers the best chance of getting significantly more power out than is put in. Proponents of fusion power say one reason the technology is safe is that the fuel needs to be constantly fed into the reactor to keep fusion happening, making a runaway reaction impossible.
Deuterium can be extracted from seawater, so there’s a virtually limitless supply of it. But only 20kg of tritium are thought to exist worldwide, so fusion power plants will have to produce it (ITER will develop technology to ‘breed’ tritium). While some radioactive waste will be produced in a fusion plant, it’ll have a lifetime of around 100 years, rather than the thousands of years from fission.
At the time of writing in September, researchers at the Joint European Torus (JET) fusion reactor in Oxfordshire were due to start their deuterium-tritium fusion reactions. “JET will help ITER prepare a choice of machine parameters to optimise the fusion power,” says Dr Joelle Mailloux, one of the scientific programme leaders at JET. These parameters will include finding the best combination of deuterium and tritium, and establishing how the current is increased in the magnets before fusion starts.
The groundwork laid down at JET should accelerate ITER’s efforts to accomplish net energy gain. ITER will produce ‘first plasma’ in December 2025 and be cranked up to full power over the following decade. Its plasma temperature will reach 150,000,000°C and its target is to produce 500 megawatts of fusion power for every 50 megawatts of input heating power.
“If ITER is successful, it’ll eliminate most, if not all, doubts about the science and liberate money for technology development,” says Luce. That technology development will be demonstration fusion power plants that actually produce electricity, where advanced reactors can build on decades of expertise. “ITER is opening the door and saying, yeah, this works – the science is there.”
