An electric company has been ordered to pay $22,400 after an employee was seriously burned in an arc flash explosion in Saskatoon.
Diversified Electric Ltd. was fined recently after pleading guilty to two charges under Saskatchewans Occupational Health and Safety Regulations.
The charges relate to failing to ensure that a worker used appropriate personal protective equipment while working close to an exposed energized electrical conductor and failing to ensure all work is sufficiently and competently supervised, the provincial government said in a news release.
The company was charged following an incident on July 31, 2008 when there was an explosion at a worksite in Saskatoon and an employee was burned.
The provinces occupational health and safety branch investigated and concluded the company failed to comply with OHS regulations and that contributed to the injury of the worker, the province said.
Mississauga Fuel Cell Electric Buses advance zero-emission public transit, leveraging hydrogen fuel cells, green hydrogen supply, rapid refueling, and extended range to cut GHGs, improve air quality, and modernize sustainable urban mobility.
Key Points
Hydrogen fuel cell buses power electric drivetrains for zero-emission service, long range, and quick refueling.
✅ Zero tailpipe emissions improve urban air quality
✅ Longer route range than battery-electric buses
✅ Hydrogen fueling is rapid, enabling high uptime
Mississauga, Ontario, is gearing up for a significant shift in its public transportation landscape with the introduction of fuel cell electric buses (FCEBs). This initiative marks a pivotal step toward reducing greenhouse gas emissions and enhancing the sustainability of public transport in the region. The city, known for its vibrant urban environment and bustling economy, is making strides to ensure that its transit system evolves in harmony with environmental goals.
The recent announcement highlights the commitment of Mississauga to embrace clean energy solutions. The integration of FCEBs is part of a broader strategy to modernize the transit fleet while tackling climate change. As cities around the world seek to reduce their carbon footprints, Mississauga’s initiative aligns with global trends toward greener urban transport, where projects like the TTC battery-electric buses demonstrate practical pathways.
What are Fuel Cell Electric Buses?
Fuel cell electric buses utilize hydrogen fuel cells to generate electricity, which powers the vehicle's electric motor. Unlike traditional buses that run on diesel or gasoline, FCEBs produce zero tailpipe emissions, making them an environmentally friendly alternative. The only byproducts of their operation are water and heat, significantly reducing air pollution in urban areas.
The technology behind FCEBs is becoming increasingly viable as hydrogen production becomes more sustainable. With the advancement of green hydrogen production methods, which use renewable energy sources to create hydrogen, and because some electricity in Canada still comes from fossil fuels, the environmental benefits of fuel cell technology are further amplified. Mississauga’s investment in these buses is not only a commitment to cleaner air but also a boost for innovative technology in the transportation sector.
Benefits for Mississauga
The introduction of FCEBs is poised to offer numerous benefits to the residents of Mississauga. Firstly, the reduction in greenhouse gas emissions aligns with the city’s climate action goals and complements Canada’s EV goals at the national level. By investing in cleaner public transit options, Mississauga is taking significant steps to improve air quality and combat climate change.
Moreover, FCEBs are known for their efficiency and longer range compared to battery electric buses, such as the Metro Vancouver fleet now operating across the region, commonly used in Canadian cities. This means they can operate longer routes without the need for frequent recharging, making them ideal for busy transit systems. The use of hydrogen fuel can also result in shorter fueling times compared to electric charging, enhancing operational efficiency.
In addition to environmental and operational advantages, the introduction of these buses presents economic opportunities. The deployment of FCEBs can create jobs in the local economy, from maintenance to hydrogen production facilities, similar to how St. Albert’s electric buses supported local capabilities. This aligns with broader trends of sustainable economic development that prioritize green jobs.
Challenges Ahead
While the potential benefits of FCEBs are clear, the transition to this technology is not without its challenges. One of the main hurdles is the establishment of a robust hydrogen infrastructure. To support the operation of fuel cell buses, Mississauga will need to invest in hydrogen production, storage, and fueling stations, much as Edmonton’s first electric bus required dedicated charging infrastructure. Collaboration with regional and provincial partners will be crucial to develop this infrastructure effectively.
Additionally, public acceptance and awareness of hydrogen technology will be essential. As with any new technology, there may be skepticism regarding safety and efficiency. Educational campaigns will be necessary to inform the public about the advantages of FCEBs and how they contribute to a more sustainable future, and recent TTC’s battery-electric rollout offers a useful reference for outreach efforts.
Looking Forward
As Mississauga embarks on this innovative journey, the introduction of fuel cell electric buses signifies a forward-thinking approach to public transportation. The city’s commitment to sustainability not only enhances its transit system but also sets a precedent for other municipalities to follow.
In conclusion, the shift towards fuel cell electric buses in Mississauga exemplifies a significant leap toward greener public transport. With ongoing efforts to tackle climate change and improve urban air quality, Mississauga is positioning itself as a leader in sustainable transit solutions. The future looks promising for both the city and its residents as they embrace cleaner, more efficient transportation options. As this initiative unfolds, it will be closely watched by other cities looking to implement similar sustainable practices in their own transit systems.
Wylfa Nuclear Project Cancellation reflects Hitachi's withdrawal, pulling £16bn from North Wales, risking jobs, reshaping UK nuclear power plans as renewables grow and Chinese involvement rises amid shifting energy market policies.
Key Points
An indefinite halt to Hitachi's Wylfa Newydd nuclear plant, removing about £16bn investment and jobs from North Wales.
✅ Hitachi withdraws funding amid changing energy market costs
✅ Puts 400 local roles and up to 10,000 construction jobs at risk
✅ UK shifts toward renewables as nuclear project support stalls
Chris Ruane said Japanese firm Hitachi’s announcement this morning about the Wylfa project would take £16 billion of investment out of the region.
He said it was the latest in a list of energy projects which had been scrapped as he responded to a statement from business secretary Greg Clark.
Mr Ruane, the Labour member for the Vale of Clywd, said: “In his statement he said the Government are relying now more on renewables, can I put the North Wales picture to him; 1,500 wind turbines were planned off the coast of North Wales. They were removed, those plans were cancelled by the private sector.
“The tidal lagoons for Wales were key to the development of the Welsh economy – the Government itself pulled the support for the Swansea Bay tidal lagoon. That had a knock-on effect for the huge lagoon planned off the coast of North Wales.
“And now today we hear of the cancellation of a £16 billion investment in the North Wales economy. This will devastate the North Wales economy. The people of North Wales need to know that the Prime Minister is batting for them and batting for the UK.”
Mr Clark blamed the changing landscape of the energy market for today’s announcement, and said Wales has been a “substantial and proud leader” in renewable energy during the UK’s green industrial revolution over recent years.
But another Labour MP from North Wales, Albert Owen, of Ynys Mon, said the Wylfa plant’s cancellation in his constituency is putting 400 jobs at risk, as well as the “potential of 8-10,000 construction jobs”, as well as hundreds of operational jobs and 33 apprenticeships.
He asked Mr Clark: “Can I say straightly can we work together to keep this project alive, to ensure that we create the momentum so it can be ready for a future developer or this developer with the right mechanism?”
The minister replied that he and his officials would “work together in a completely open-book way on the options” to try and salvage the project.
But in the Lords, Labour former security minister Lord West of Spithead said the UK’s nuclear industry was in crisis, noting that Europe is losing nuclear power as well.
“In the 1950s our nation led the world in nuclear power generation and decisions by successive governments, of all hues, have got us in the position today where we cannot even construct a large civil nuclear reaction,” he told peers at question time.
Lord West asked: “Are we content that now the only player seems to be Chinese and that by 2035… we are happy for the Chinese to control one third of the energy supply of our nation?”
Business, Energy and Industrial Strategy minister Lord Henley said the Government had hoped for a better announcement from Hitachi but that was not the case.
He said costs in the nuclear sector were rising, amid setbacks at Hinkley Point C, while costs for many renewables were coming down and this was one of the reasons for the problem.
Tory former energy secretary Lord Howell of Guildford said the Chinese were in “pole position” for the rebuilding and replacement “of our nuclear fleet” and this would have a major impact on UK energy policy and plans to meet net zero targets in the 2030s.
Plaid Cymru’s Lord Wigley warned that putting the Wylfa Newydd on indefinite hold would cause economic planning blight in north-west Wales and urged the Government to raise the level of support allocated to the region.
Lord Henley acknowledged the announcement was not welcome but added: “We remain committed to nuclear power. We will look to see what we can do. We still have a great deal of expertise in this country and we can work on that.”
Newfoundland and Labrador electricity rate hike examines a proposed 18.6% increase under the PUB's Rate Stabilization Plan, driven by oil prices at Holyrood, with Consumer Advocate concerns over rate shock and use of RSP balances.
Key Points
A proposed 18.6% July 2017 increase under the RSP, driven by oil prices, now under PUB review for potential mitigation.
✅ PUB flags potential rate shock from proposed adjustment
✅ RSP balances cited to offset increases without depleting fund
How much of a rate hike is reasonable for users of electricity in Newfoundland and Labrador?
That's a question before the Public Utilities Board (PUB) as it examines an application by Newfoundland and Labrador Hydro, which could see consumers pay up to 18.6 per cent more as of July 1, reflecting regional pressures seen in Nova Scotia, where regulators approved a 14% rate hike earlier this year.
"The estimated rate increase for July 2017 is such a significant increase that it may be argued that it would cause rate shock," said the PUB, asking the company to revise its application.
NL Hydro said the price adjustment is part of what happens every year through the Rate Stabilization Plan (RSP), which is used to offset the ups and downs of oil prices.
"The cost of fuel is volatile and as long as we rely on oil-fired generation at Holyrood, customers will continue to be impacted by this electricity price uncertainty," said the company in a statement to CBC News.
It noted that customers received a break from RSP adjustments in 2015 and 2016, even as costs from the Muskrat Falls project begin to be reflected.
The PUB noted that under the rate stabilization plan, prices have gone up or down by about 10 per cent in the past.
The regulatory board said the impact of the latest request would be a 27.6 per cent hike to Newfoundland Power, with "an estimated average end customer impact of 18.6 per cent."
Hydro's estimates are based on an average price for oil of $81.40 per barrel from July 2017 to June 2018, according to the PUB.
'Unacceptable' burden: Consumer Advocate
"To burden ratepayers with an 18 per cent rate increase is unacceptable," said Consumer Advocate Dennis Browne, echoing pushback in Nova Scotia, where the premier urged regulators to reject a 14% hike at the time.
Browne is arguing that there is money in the RSP to reduce the proposed increase, including the possibility of a lump-sum bill credit for customers.
"These ratepayer balances — which, according to NL Power, totals $77.4 million — are not the property of Hydro," he wrote in a letter to the PUB.
"No utility has the right to squirrel away ratepayers' money to be used by that utility for some future purpose. The Board has jurisdiction over those balances," Browne said.
Browne also wants the RSP overhauled so that it can be applied to price fluctuations every quarter, as opposed to annually.
Hydro has expressed concern that depleting the rate stabilization fund would lead to other, more significant, rate increases in the future.
It said several alternatives to mitigate high rates have been provided to the PUB, which has final say, similar to how Manitoba Hydro scaled back a planned increase in the next year.
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.”
Maritime Electric Hurricane Irma Response details utility crews aiding Turks and Caicos with power restoration, storm recovery, debris removal, and essential services, coordinated with Fortis Inc., despite limited equipment, heat, and over 1,000 downed poles.
Key Points
A utility mission restoring power and essential services in Turks and Caicos after Irma, led by Maritime Electric.
✅ Over 1,000 poles down; crews climbing without bucket trucks
✅ Restoring hospitals, water, and communications first
✅ Fortis Inc. coordination; 2-3 week deployment with follow-on crews
Maritime Electric has sent a crew to help in the clean up and power restoration of Turks and Caicos after the Caribbean island was hit by Hurricane Irma, a storm that also saw FPL's massive response across Florida.
They arrived earlier this week and are working on removing debris and equipment so when supplies arrive, power can be brought back online, and similar mutual aid deployments, including Canadian crews to Florida, have been underway as well.
Fortis Inc., the parent company for Maritime Electric operates a utility in Turks and Caicos.
Kim Griffin, spokesperson for Maritime Electric, said there are over 1000 poles that were brought down by the storm, mirroring Florida restoration timelines reported elsewhere.
"It's really an intense storm recovery," she said. 'Good spirits'
The crew is working with less heavy equipment than they are used to, climbing poles instead of using bucket trucks, in hot and humid weather.
Griffin said their focus is getting essential services restored as quckly as possible, similar to progress in Puerto Rico's restoration efforts following recent hurricanes.
The crew will be there for two or three weeks and Griffin said Maritime Electric may send another group, as seen with Ontario's deployment to Florida, to continue the job.
She said the team has been well received and is in "good spirits."
"The people around them have been very positive that they're there," she said.
"They've said it's just been overwhelming how kind and generous the people have been to them."
BC Hydro LNG Load Forecast signals rising electricity demand from LNG Canada, Woodfibre, and Tilbury, aligning Site C dam capacity with BCUC review, hydroelectric supply, and a potential fourth project in feasibility study British Columbia.
Key Points
BC Hydro's projection of LNG-driven power demand, guiding Site C capacity, BCUC review, and grid planning.
✅ Includes LNG Canada, Woodfibre, and Tilbury load requests
✅ Aligns Site C hydroelectric output with industrial electrification
✅ Notes feasibility study for a fourth LNG project
Despite recent project cancellations, such as the Siwash Creek independent power project now in limbo, BC Hydro still expects three LNG projects — and possibly a fourth, which is undergoing a feasibility study — will need power from its controversial and expensive Site C hydroelectric dam.
In a letter sent to the British Columbia Utilities Commission (BCUC) on Oct. 3, BC Hydro’s chief regulatory officer Fred James said the provincially owned utility’s load forecast includes power demand for three proposed liquefied natural gas projects because they continue to ask the company for power.
The letter and attached report provide some detail on which of the LNG projects proposed in B.C. are more likely to be built, given recent project cancellations.
The documents are also an attempt to explain why BC Hydro continues to forecast a surge in electricity demand in the province, as seen in its first call for power in 15 years driven by electrification, even though massive LNG projects proposed by Malaysia’s state owned oil company Petronas and China’s CNOOC Nexen have been cancelled.
An explanation is needed because B.C.’s new NDP government had promised the BCUC would review the need for the $9-billion Site C dam, which was commissioned to provide power for the province’s nascent LNG industry, amid debates over alternatives like going nuclear among residents. The commission had specifically asked for an explanation of BC Hydro’s electric load forecast as it relates to LNG projects by Wednesday.
The three projects that continue to ask BC Hydro for electricity are Shell Canada Ltd.’s LNG Canada project, the Woodfibre LNG project and a future expansion of FortisBC’s Tilbury LNG storage facility.
None of those projects have officially been sanctioned but “service requests from industrial sector customers, including LNG, are generally included in our industrial load forecast,” the report noted, even as Manitoba Hydro warned about energy-intensive customers in a separate notice.
In a redacted section of the report, BC Hydro also raises the possibility of a fourth LNG project, which is exploring the need for power in B.C.
“BC Hydro is currently undertaking feasibility studies for another large LNG project, which is not currently included in its Current Load Forecast,” one section of the report notes, though the remainder of the section is redacted.
The Site C dam, which has become a source of controversy in B.C. and was an important election issue, is currently under construction and, following two new generating stations recently commissioned, is expected to be in service by 2024, a timeline which had been considered to provide LNG projects with power by the time they are operational.
BC Hydro’s letter to the BCUC refers to media and financial industry reports that indicate global LNG markets will require more supply by 2023.
“While there remains significant uncertainty, global LNG demand will continue to grow and there is opportunity for B.C. LNG,” the report notes.
