A multibillion-dollar plan to keep four aging Pickering nuclear reactors running until mid-century shouldn't go ahead without studying the potential impact on Toronto from catastrophic accidents or terrorist attacks, environmental groups have urged Canada's nuclear safety watchdog.
"In our post-Chernobyl and post-Sept. 11th world, it would be unacceptable to build Pickering where it is today," said Tristan Cheery, a spokesperson for a York University student group that champions off-grid electricity.
Greepeace's Shawn-Patrick Stensil said that the environmental impact study must include damage assessment from a terrorist assault should an aircraft be used to crash into the aged Pickering reactors, which are concrete shielded, or into the unprotected control room.
Staff at the commission had earlier rejected that view, concluding that security issues "do not warrant special consideration in the environmental assessment." But official documents reveal the commission is demanding new nuclear power reactors in Canada be built to withstand an aircraft crash.
"Theirs is obviously a double standard when it come to terrorism standards for older reactors," Stensil told the hearing.
On Monday, Greenpeace filed a petition asking the environment commissioner in the federal auditor general's office to investigate the apparent double standard.
The groups also complained that the Pickering plan is being rushed through without a full-fledged hearing permitted under the federal environmental protection law.
"You're spinning the public around in circles," Stensil told the Canadian Nuclear Safety Commission.
The overhaul can't start until the commission accepts study findings on the environmental impact of keeping reactors running for 30 years beyond original shutdown dates.
An environmental study would likely take a year but has not yet started. The arguments before the commission centred on the study's limited scope – conditions that were largely hammered out between OPG officials and commission staff.
The seven commissioners who direct the federal regulatory agency must decide whether to approve the proposed guidelines for the environmental impact study, amend them or instruct their staff to renegotiate. Their decision isn't expected until February at the earliest, judging by past practice.
The key issue was whether Toronto should automatically be included in the environmental impact study. The current study zone covers Pickering and surrounding region but extends west only up to Scarborough. Commission staff and OPG officials defended the limited boundaries.
"Should the community identify significant concerns, we would of course extend the boundary into Metro Toronto to address those concerns," said Laurie Swami, an OPG licensing specialist Laurie Swami.
But the province's response plan in the event of radiation release already covers up to 50 kilometres from the Pickering reactor site, taking in all of Toronto, said Joe Verderami, an official with Emergency Management Ontario told the hearing.
He said the provincial agency considers people that far away might need preventative treatment if substantial radiation was released from the reactors.
Downed Power Line Vehicle Safety: Follow stay-in-the-car protocol, call 911, avoid live wires and utility poles, and use the bunny hop to escape only for fire. Electrical hazards demand emergency response caution.
Key Points
Stay in the car, call 911, and use a bunny hop escape only if fire threatens during downed power line incidents.
✅ Stay in vehicle; tell bystanders to keep back and call 911.
✅ Exit only for fire; jump clear and bunny hop away.
✅ Treat all downed lines as live; avoid paths to ground.
Ameren Illinois and Safe Electricity are urging the public to stay in their cars and call 911 in the event of an accident involving a power pole that brings down power lines on or around the car.
In a media simulation Tuesday at the Ameren facility on West Lafayette Avenue, Ameren Illinois employees demonstrated the proper way to react if a power line has fallen on or around a vehicle, as some utilities consider on-site staffing measures during outbreaks. Although the situation might seem rare, Illinois motorists alone hit 3,000 power poles each year, said Krista Lisser, communications director for Safe Energy.
“We want to get the word out that, if you hit a utility pole and a live wire falls on your vehicle, stay in your car,” Lisser said. “Our first reaction is we panic and think we need to get out, a sign of the electrical knowledge gap many people have. That’s not the case, you need to stay in because, when that live wire comes down, electricity is all around you. You may not see it, it may not arc, it may not flash, you may not know if there’s electricity there.”
Should someoneinvolved in such an accident see a good Samaritan attempting to help, he should try to tell the would-be rescuer to stay back to prevent injury to the Samaritan, Ameren Illinois Communications Executive Brian Bretsch said.
“We have seen instances where someone comes up and wants to help you,” Bretsch said. “You want to yell, ‘Please stay away from the vehicle. Everyone is OK. Please stay away.’ You’ll see … instances every now and then where the Samaritan will come up, create that path to ground and get injured, and there are also climbers seeking social media glory who put themselves at risk.”
The only instance in which one should exit a car in the vicinity of a downed wire is if the vehicle is on fire and there is no choice but to exit. In that situation, those in the car should “bunny hop” out of the car by jumping from the car without touching the car and the ground at the same time, Bretsch and Lisser said.
After the initial jump, those escaping the vehicle should continue jumping with both feet together and hands tucked in and away from danger until they are safely clear of the downed wire.
It’s important for everyone to be informed, because an encounter with a live wire could easily result in serious injury, as in the Hydro One worker injury case, or death, Lisser said.
“They’re so close to our roads, especially in our rural communities, that it’s quite a common occurrence,” Lisser said. “Just stay away from (downed lines), especially after storms and amid grid oversight warnings that highlight reliability risks … Always treat a downed line as a live wire. Never assume the line is dead.”
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.”
Tesla Electric UK Expansion signals retail energy entry, leveraging Powerwall VPPs for grid services, dynamic pricing, and energy trading, building on Texas success and Octopus Energy ties to buy and sell electricity automatically.
Key Points
Tesla's plan to launch Tesla Electric in the UK, using Powerwall VPPs to retail energy, trade power, and hedge peaks.
✅ Retail energy model built on Powerwall VPP aggregation
✅ Automated buy-sell arbitrage with dynamic pricing
✅ Leverages prior UK approval and Octopus Energy ties
According to a new job posting, Tesla Electric, Tesla’s new electric utility division, is preparing to expand in the United Kingdom as regions such as California grid planners look to electric vehicles for stability to manage demand.
Late last year, after gaining experience through its virtual power plants (VPPs), including response during California blackouts that pressured the grid, Tesla took things a step further with the launch of “Tesla Electric.”
Instead of reacting to specific “events” and providing services to your local electric utilities through demand response programs, as Tesla Powerwall owners have done in VPPs in California, Tesla Electric is actively and automatically buying and selling electricity for Tesla Powerwall owners – providing a buffer against peak prices.
The company has listed a new job posting for a role called “Head of Operations, Tesla Electric – Retail Energy.”
This has been in the works for a while now. Tesla used to have a partnership with Octopus Energy in the UK for special electricity rates for its owners, during a period when UK EV inquiries surged amid a fuel supply crisis, but it seemed to be a stepping stone before it would itself become an energy provider in the market.
In 2020, Tesla was officially approved as an electricity retailer in the UK. Now it looks like Tesla is going to use this approval with the launch of Tesla Electric.
Medicine Hat Bitcoin Mining Deal delivers 42 MW electricity to Hut 8, enabling blockchain data centres, cryptocurrency mining expansion, and economic diversification in Alberta with low-cost power, land lease, and rapid construction near Unit 16.
Key Points
A pact to supply 42 MW and lease land, enabling Hut 8's blockchain data centres and crypto mining growth in Alberta.
✅ 42 MW electricity from city; land lease near Unit 16
✅ Hut 8 expands to 60.7 MW; blockchain data centres
✅ 100 temporary jobs; 42 ongoing roles in Alberta
The City of Medicine Hat has agreed to supply electricity and lease land to a Toronto-based cryptocurrency mining company, at a time when some provinces are pausing large new crypto loads in a deal that will see $100 million in construction spending in the southern Alberta city.
The city will provide electric energy capacity of about 42 megawatts to Hut 8 Mining Corp., which will construct bitcoin mining facilities near the city's new Unit 16 power plant.
The operation is expected to be running by September and will triple the company's operating power to 60.7 megawatts, Hut 8 said, amid broader investments in new turbines across Canada.

"The signing of the electricity supply agreement and the land lease represents a key component in achieving our business plan for the roll-out of our BlockBox Data Centres in low-cost energy jurisdictions," said the company's board chairman, Bill Tai, in a release.
"[Medicine Hat] offers stable, cost-competitive utility rates and has been very welcoming and supportive of Hut 8's fast-paced growth plans."
In bitcoin mining operations, rows upon rows of power-consuming computers are used to solve mathematical puzzles in exchange for bitcoins and confirm crytopcurrency transactions. The verified transactions are then added to the public ledger known as the blockchain.
Hut 8's existing 18.7-megawatt mining operation at Drumheller, Alta. — a gated compound filled with rows of shipping containers housing the computers — has so far mined 750 bitcoins. Bitcoin was trading Tuesday morning for about $11,180.
Medicine Hat Mayor Ted Clugston says the deal is part of the city's efforts to diversify its economy.
We've made economic development a huge priority down here because we were hit very, very hard by the oil and gas decline," he said, noting that being the generator and vendor of its own electricity puts the city in a uniquely good position.
"Really we're just turning gas into electricity and they're taking that electricity and turning it into blockchain, or ones and zeroes."
Elsewhere in Canada, using more electricity for heat has been urged by green energy advocates, reflecting broader electrification debates.
Hut 8 says construction of the facility is starting right away and will create about 100 temporary jobs. The project is expected to be finished by the third-quarter of this year.
The Medicine Hat mining operation will generate 42 ongoing jobs for electricians, general labourers, systems technicians and security staff.
Los Angeles Power Station Fire prompts LADWP to shut a Northridge/Reseda substation, causing a San Fernando Valley outage amid a heatwave; high-voltage equipment and mineral oil burned as 94,000 customers lost power, elevator rescues reported.
Key Points
An LADWP substation fire in Northridge/Reseda caused a major outage; 94,000 customers affected as crews restore power.
✅ Fire started around 6:52 p.m.; fully extinguished by 9 p.m.
✅ High-voltage gear and mineral oil burned; no injuries reported.
✅ Outages hit Porter Ranch, Reseda, West Hills, Granada Hills.
About 94,000 customers were without electricity Saturday night after the Los Angeles Department of Water and Power shut down a power station in the northeast San Fernando Valley that caught fire, the agency said.
The fire at the station in the Northridge/Reseda area of Los Angeles started about 6:52 p.m. and involved equipment that carries high-voltage electricity and distributes it at lower voltages to customers in the surrounding area, the department said, even as other utilities sometimes deploy wildfire safety shut-offs to reduce risk during dangerous conditions.
The department shut off power to the station as a precautionary move, and it is restoring power now that the fire has been put out, similar to restoration after intentional shut-offs in other parts of California. Initially, 140,000 customers were without power. That number had been cut to 94,000 by 11 p.m.
The power outage comes as much of California baked in heat that broke records, and rolling blackout warnings were issued as the grid strained. A record that stood 131 years in Los Angeles was snapped when the temperature spiked at 98 degrees downtown.
People reported losing power in Porter Ranch, Winnetka, West Hills, Canoga Park, Woodland Hills, Granada Hills, North Hills, Reseda and Chatsworth, KABC TV reported, highlighting electricity inequality across communities.
Shortly after the blaze broke out, firefighters found a huge container of mineral oil that is used to cool electrical equipment on fire, Los Angeles Fire Department spokesman Brian Humphrey told the Los Angeles Times. The incident underscores infrastructure risks that in some regions have required a complete grid rebuild after severe storms.
Firefighters had the blaze under control by 8:30 p.m. and were able to put it out by 9 p.m., Humphrey said. "These were fierce flames, with smoke towering more than 300 feet into the sky," he told the newspaper.
No one was injured.
Firefighters rescued people who were stranded in elevators, Humphrey said.
Ofgem Renewables Obligations drive supplier payments for renewables fees, feed-in tariffs, and renewable generation, with non-payment risking supply licences amid the price cap and volatile wholesale prices across the UK energy market.
Key Points
Mandatory payments by suppliers funding renewables via feed-in tariffs; non-payment can trigger supply licence revoking.
✅ Covers Renewables Obligation and Feed-in Tariff scheme compliance.
✅ Non-payment can lead to Ofgem action and licence loss.
✅ Affected by price cap and wholesale price volatility.
Seven small British energy suppliers owe a total of 34 million pounds ($43.74 million) in renewables fees, amid a renewables backlog that has stalled projects, and could face losing their supply licences if they cannot pay, energy regulator Ofgem reports.
Under Britain’s energy market rules, suppliers of energy must meet so-called renewables obligations and feed-in tariffs, including households' ability to sell solar power back to energy firms, which are imposed on them by the government to help fund renewable power generation.
Several small energy companies have gone bust over the past two years, a trend echoed by findings from a global utility study on renewable priorities, as they struggled to pay the renewables fees and as their profits were affected by a price cap on the most commonly used tariffs and fluctuating wholesale prices, even as a 10 GW contract brings new renewable capacity onto the UK grid.
Ofgem has called on the companies to make necessary payments by Oct. 31, as moves to offer community-generated power to all UK customers progress.
“If they do not pay Ofgem could start the process of revoking their licences to supply energy,” it said in a statement, as offshore wind power continues to scale nationwide.
The seven suppliers are, amid debates over clean energy impacts, Co-Operative Energy Limited; Flow Energy Limited; MA Energy Limited; Nabuh Energy Limited; Robin Hood Energy Limited; Symbio Energy Limited and Tonik Energy Limited. ($1 = 0.7773 pounds)
