The City of Winnipeg is proposing a landfill gas and resource recovery project that could turn thousands of tonnes of harmful greenhouse gases into a renewable energy resource.

The city is currently asking for bidders to design, build, finance and operate a project at the Brady Road landfill to collect and flare gas for a 20-year term.

Proposals from companies wanting to use the gas from the landfill are being accepted until February 26, after which the city will have an evaluation period.

“There’s a number of ideas out there. Really the whole idea of the proposal is that we want the market to tell us what they think is the best thing to do,” explained Darryl Drohomerski, manager of the solid wastes department for the City of Winnipeg.

“We’re not the experts in it at all, we’re putting it out so that companies bidding on it would have the expertise to do that work.”

The requirements of the proposal are flexible enough to allow bidders to use the gas as they wish, so long as their design is able to flare 1,000 standard cubic feet per metre for their 20-year term. The technology to extract the gas from the landfill is similar to drilling oil wells and is essentially the same with each company. What separates the bidders is what they would like to do with the gas once it has been extracted.

“The landfill needs to be engineered with a series of gas wells extracting the biogas as it is produced,” explained Jan Oleszkiewicz, professor of civil engineering at the University of Manitoba.

“The gas may then be used to run generators directly or can be used as it is cleaned from contaminants.”

Oleszkiewicz further explained that the procedure is fairly complex and significantly adds to the costs of operating a landfill.

“Careful operation is necessary as this gas is explosive when mixed with air,” said Oleszkiewicz. Two of the most standard uses for the gas are to convert it into electricity or into fuel for heating buildings.

“A company could build a generating station to produce electricity, or you could do things like convert it into a gas that you would use to run a fleet of buses or something like that,” said Drohoerski.

The gas can be easily converted into electricity, although it would not be enough to fill the high energy demand posed by a large city such as Winnipeg said Oleskiewicz.

“However biogas extraction from landfills appears to be the right thing to do due to the current concern for reducing the amount of greenhouse-effect producing gases released to the atmosphere,” said Oleszkiewicz. Bidders also have the option proposing a system of recovering and reusing material destined for disposal. “There are a number of new firms out there that will do things like take all of your garbage and convert it into an energy source or a heat source that... may be beneficial to a city at large over what we’re doing right now,” said Drohoerski.

“In the U.S., for example, there are a lot of landfills in large cities that have what’s called a waste-to-energy plant.... All the garbage is put into a giant incinerator and the garbage is burned, and then is converted into electricity.”

The University of Manitoba has expressed interest in partnering with the City of Winnipeg on the project.

“We could offset almost half of the university’s natural gas consumption. It’s amazing. That project will pay for itself in less than five years. It’s just an incredible opportunity for saving money,” said Mike Ferley, U of M energy advocate, in an interview with the Manitoban in October 2008.

Ferley said that working on this project would improve the university’s sustainability drastically. “This is a $15 million project and if we were to fund (the project) out of endowment funds we’d be looking very green. Super green.”

Similar projects have been done in cities across Canada, such as Vancouver, Edmonton and Calgary.

The city is hoping for construction to begin this September, though some form of operation is predicted to start earlier in the year.

BC Hydro Expects To See Electricity Usage Rise This Holiday Season

BC Hydro Holiday Electricity Usage is set to rise as energy demand increases during peak 4-10 pm on Christmas and Boxing Day, driven by larger gatherings, more cooking, and eased COVID-19 restrictions province-wide.

 

Key Points

Expected rise in power demand on Christmas and Boxing Day evenings versus 2020, driven by larger gatherings and cooking.

✅ Peak hours 4-10 pm expected to rise in provincial load.

✅ 2020 saw 4% and 7% drops vs 2019 on Christmas and Boxing Day.

✅ Holiday lighting adds ~3% to use; switching to LED can save ~$40.

 

BC Hydro data showed residential electricity load in the Cariboo and throughout the province, even as drought affects generation dynamics heading into winter, dropped on Christmas Day and Boxing Day in 2020.

Northern Community Relations Manager, Bob Gammer, said the decrease was due in part to more people following the COVID-19 restrictions and not getting together for big meals, even though 2018 Earth Hour usage increased elsewhere illustrates how behavior can sometimes raise demand.

However, this year Gammer said between 4 and 10 pm on those two days, BC Hydro does expect to see a change in overall usage, aligning with all-time high demand trends reported recently in B.C.

“On Christmas Day and Boxing Day, we expect to see increases through those hours and a little bit more so between 4 and 10 pm we should see the amount of power being consumed across the province, as record-breaking 2021 demand indicated earlier, going up compared to what it was on those two days last year.”

In 2020 on Christmas Day evening hydro usage dropped by over 4 percent and Boxing Day evening decreased by 7 percent compared to 2019, whereas regions like Calgary's winter demand have seen spikes during extreme cold.

Gammer added after BC Hydro surveyed their customers and introduced a winter payment plan, they expect to see a lot more cooking happening on Christmas Day and Boxing Day this year as people are intending to have larger gatherings and visit friends.

We asked Gammer about hydro usage when it comes to homes decked out for the holidays, and how that compares to newer loads like crypto mining activity in B.C.

“The Christmas lighting displays people have, not just indoors but outdoors as well, what we’re seeing is about a 3 percent increase in electricity consumption overall through the Christmas season. If people switch, if you still have older lights that are incandescent, switch those over to LED, and through the season it could wind up saving you $40 in electricity just switching over about 8 strings of lights to LED.”

State-owned electricity generation firm could save Britons nearly 21bn a year?

Great British Energy could cut UK electricity costs via public ownership, investing in clean energy like wind, solar, tidal, and nuclear, curbing windfall profits, stabilizing bills, and reinvesting returns through a state-backed generator.

 

Key Points

A proposed state-backed UK generator investing in clean power to cut costs and return gains to taxpayers.

✅ Publicly owned investment in wind, solar, tidal, and nuclear

✅ Cuts electricity bills by reducing generators' windfall profits

✅ Funded via bonds or asset buyouts; non-profit operations

 

A publicly owned electricity generation firm could save Britons nearly £21bn a year, according to new analysis that bolsters Labour’s case to launch a national energy company if the party gains power.

Thinktank Common Wealth has calculated that the cost of generating electricity to power homes and businesses could be reduced by £20.8bn or £252 per household a year under state ownership, according to a report seen by the Guardian.

The Labour leader, Keir Starmer, has committed to creating “a publicly owned national champion in clean energy” named Great British Energy.

Starmer is yet to lay out the exact structure of the mooted company, although he has said it would not involve nationalising existing assets, or become involved in the transmission grid or retail supply of energy.

Starmer instead hopes to create a state-backed entity that would invest in clean energy – wind, solar, tidal, nuclear, large-scale storage and other emerging technologies – creating jobs and ensuring windfalls from the growth in low carbon power feed back to the government.

The Common Wealth report, which analysed scenarios for reforming the electricity market, said that a huge saving on electricity costs could be made by buying out assets such as wind, solar and biomass generators on older contracts and running them on a non-profit basis. Funding the measure could require a government bond issuance, or some form of compulsory purchase process.

Last year the government attempted to get companies operating low carbon generators, including nuclear power plants, on older contracts to switch to contracts for difference (CfD), allowing any outsized profits to flow back to taxpayers. However, the government later decided to tax eligible firms through the electricity generator levy instead.

The Common Wealth study concluded that a publicly owned low carbon energy generator would best deliver on Britain’s climate and economic goals, would eliminate windfall profits made by generators and would cut household bills significantly.

MPs and campaigners have argued that Britain’s energy companies should be nationalised since the energy crisis, even as coal-free records have multiplied and renewables still need more support, which has resulted in North Sea oil and gas producers and electricity generators making windfall profits, and a string of retail suppliers collapsing, costing taxpayers billions. Detractors of nationalisation in energy argue it can stifle innovation and expose taxpayers to huge financial risks.

Common Wealth pointed out that more than 40% of the UK’s offshore wind generation capacity was publicly owned by overseas national entities, meaning the benefits of high electricity prices linked to the war in Ukraine had flowed back to other governments.

The study found the publicly owned generator model would create more savings than other options, including a drive for voluntary CfDs; splitting the generation market between low carbon and fossil fuel sources at a time when wind and solar have outproduced nuclear, and a “single buyer model” with nationalised retail suppliers.

National Steel Car appealing decision in legal challenge of Ontario electricity fee it calls an unconstitutional tax

Ontario Global Adjustment Appeal spotlights Ontario's electricity fee, regulatory charge vs tax debate, FIT contracts, green energy policy, and constitutional challenge as National Steel Car contests soaring power costs before the Ontario Superior Court.

 

Key Points

Court challenge over Ontario's global adjustment fee, disputing its status as a regulatory charge instead of a tax.

✅ Challenges classification of global adjustment as tax vs regulatory charge.

✅ Focuses on FIT contracts, renewable energy payments, power cost impacts.

✅ Appeals Ontario ruling; implications for ratepayers and policy.

 

A manufacturer of steel rail cars is pursuing an appeal after its lawsuit challenging the constitutionality of a major Ontario electricity fee was struck down earlier this year.

Lawyers for Hamilton, Ont.-based National Steel Car Ltd. filed a notice of appeal in July after Ontario Superior Court Justice Wendy Matheson ruled in June that an electricity fee known as the global adjustment charge was a regulatory charge, and not an unconstitutional tax used to finance policy goals, as National Steel Car alleges.

The company, the decision noted, began its legal crusade last year after seeing its electricity bills had “increased dramatically” since the Ontario government passed green energy legislation nearly a decade ago, and amid concerns that high electricity rates are hurting Ontario manufacturers.

Under that legislation, the judge wrote, “private suppliers of renewable energy were paid to ’feed in’ energy into Ontario’s electricity grid.” The contracts for these so-called “feed-in tariff” contracts, or FIT contracts, were the “primary focus” of the lawsuit.

“The applicant seeks a declaration that part of the amount it has paid for electricity is an unconstitutional tax rather than a valid regulatory charge,” the judge added. “More specifically, it challenges part of the Global Adjustment, which is a component of electricity pricing and incorporates obligations under FIT contracts.”

Chiefly representing the difference between Ontario’s market price for power and the guaranteed price owed to generators, global adjustment now makes up the bulk of the commodity cost of electricity in the province. The fee has risen over the past decade, amid calls to reject steep Nova Scotia rate hikes as well — costing electricity customers $37 billion in global adjustment from 2006 to 2014, according to the province’s auditor general — because of investments in the electricity grid and green-energy contracts, among other reasons.

National Steel Car argued the global adjustment is a tax, and an unconstitutional one at that because it violated a section of the Constitution Act requiring taxes to be authorized by the legislature. The company also said the imposition of the global adjustment broke an Ontario law requiring a referendum to be held for new taxes.

The province, Justice Matheson wrote, had argued “that it is plain and obvious that these applications will fail.” In a decision released in June, the judge granted motions to strike out National Steel Car’s applications.

“The Global Adjustment,” she added, “is not a tax because its purpose, in pith and substance, is not to tax, and it is a regulatory charge and therefore, again, not a tax.”

Now, National Steel Car is arguing that the judge erred in several ways, including in fact, “by finding that the FIT contracts must be paid, when they can be cancelled.”

There has been a change in government at Queen’s Park since National Steel Car first filed its lawsuit last year, and that change has put green energy contracts under fire. The Progressive Conservative government of new Premier Doug Ford has already made a number of decisions on the electricity file, such as moving to cancel and wind down more than 750 renewable energy contracts, as well as repealing the province’s Green Energy Act.

The Tories also struck a commission of inquiry into the province’s finances that warned the global adjustment “may be struck down as unconstitutional,” a warning delivered amid cases where Nova Scotia's regulator approved a 14% rate hike in a high-profile decision.

“There is a risk that a court may find the global adjustment is not a valid regulatory charge if shifting costs over a longer period of time inadvertently results in future ratepayers cross-subsidizing today’s ratepayers,” the commission’s report said.

A spokesperson for Ontario’s Ministry of Energy, Northern Development and Mines said in an email that it would be “inappropriate to comment about the specifics of any case before the courts or currently under arbitration.”

National Steel Car is also prepared to fight its case all the way up to the Supreme Court of Canada, according to its lawyer.

“What is clear from our proceeding with the appeal is National Steel Car has every intention of seeing that lawsuit through to its conclusion if this government isn’t interested or prepared to reasonably settle it,” Jerome Morse said.

Spent fuel removal at Fukushima nuclear plant delayed up to 5 years

Fukushima Daiichi decommissioning delay highlights TEPCO's revised timeline, spent fuel removal at Units 1 and 2, safety enclosures, decontamination, fuel debris extraction by robot arm, and contaminated water management under stricter radiation control.

 

Key Points

A government revised schedule pushing back spent fuel removal and decommissioning milestones at Fukushima Daiichi.

✅ TEPCO delays spent fuel removal at Units 1 and 2 for safety.

✅ Enclosures, decontamination, and robotics mitigate radioactive risk.

✅ Contaminated water cut target: 170 tons/day to 100 by 2025.

 

The Japanese government decided Friday to delay the removal of spent fuel from the Fukushima Daiichi nuclear power plant's Nos. 1 and 2 reactors by as much as five years, casting doubt on whether it can stick to its timeframe for dismantling the crippled complex.

The process of removing the spent fuel from the units' pools had previously been scheduled to begin in the year through March 2024.

In its latest decommissioning plan, the government said the plant's operator, Tokyo Electric Power Company Holdings Inc., will not begin the roughly two-year process (a timeline comparable to major reactor refurbishment programs seen worldwide) at the No. 1 unit at least until the year through March 2028 and may wait until the year through March 2029.

Work at the No. 2 unit is now slated to start between the year through March 2025 and the year through March 2027, it said.

The delay is necessary to take further safety precautions such as the construction of an enclosure around the No. 1 unit to prevent the spread of radioactive dust, and decontamination of the No. 2 unit, even as authorities have begun reopening previously off-limits towns nearby, the government said. It is the fourth time it has revised its schedule for removing the spent fuel rods.

"It's a very difficult process and it's hard to know what to expect. The most important thing is the safety of the workers and the surrounding area," industry minister Hiroshi Kajiyama told a press conference.

The government set a new goal of finishing the removal of the 4,741 spent fuel rods across all six of the plant's reactors by the year through March 2032, amid ongoing debates about the consequences of early nuclear plant closures elsewhere.

Plant operator TEPCO has started the process at the No. 3 unit and already finished at the No. 4 unit, which was off-line for regular maintenance at the time of the disaster. A schedule has yet to be set for the Nos. 5 and 6 reactors.

While the government maintained its overarching timeframe of finishing the decommissioning of the plant 30 to 40 years from the 2011 crisis triggered by a magnitude 9.0 earthquake and tsunami, there may be further delays, even as milestones at other nuclear projects are being reached worldwide.

The government said it will begin removing fuel debris from the three reactors that experienced core meltdowns in the year through March 2022, starting with the No. 2 unit as part of broader reactor decommissioning efforts.

The process, considered the most difficult part of the decommissioning plan, will involve using a robot arm, reflecting progress in advanced reactors technologies, to initially remove small amounts of debris, moving up to larger amounts.

The government also said it will aim to reduce the pace at which contaminated water at the plant increases. Water for cooling the melted cores, mixed with underground water, amounts to around 170 tons a day. That number will be brought down to 100 tons by 2025, it said.

The water is being treated to remove the most radioactive materials and stored in tanks on the plant's grounds, but already more than 1 million tons has been collected and space is expected to run out by the summer of 2022.

British Columbia Halts Further Expansion of Self-Driving Vehicles

BC Autonomous Vehicle Ban freezes new driverless testing and deployment as BC develops a regulatory framework, prioritizing safety, liability clarity, and road sharing with pedestrians and cyclists while existing pilot projects continue.

 

Key Points

A moratorium pausing new driverless testing until a safety-first regulatory framework and clear liability rules exist.

✅ Freezes new AV testing and deployment provincewide

✅ Current pilot shuttles continue under existing approvals

✅ Focus on safety, liability, and road-user integration

 

British Columbia has halted the expansion of fully autonomous vehicles on its roads. The province has announced it will not approve any new applications for testing or deployment of vehicles that operate without a human driver until it develops a new regulatory framework, even as it expands EV charging across the province.


Safety Concerns and Public Questions

The decision follows concerns about the safety of self-driving vehicles and questions about who would be liable in the event of an accident. The BC government emphasizes the need for robust regulations to ensure that self-driving cars and trucks can safely share the road with traditional vehicles, pedestrians, and cyclists, and to plan for infrastructure and power supply challenges associated with electrified fleets.

"We want to make sure that British Columbians are safe on our roads, and that means putting the proper safety guidelines in place," said Rob Fleming, Minister of Transportation and Infrastructure. "As technology evolves, we're committed to developing a comprehensive framework to address the issues surrounding self-driving technology."


What Does the Ban Mean?

The ban does not affect current pilot projects involving self-driving vehicles that already operate in BC, such as limited shuttle services and segments of the province's Electric Highway that support charging and operations.


Industry Reaction

The response from industry players working on autonomous vehicle technology has been mixed, amid warnings of a potential EV demand bottleneck as adoption ramps up. While some acknowledge the need for clear regulations, others express concern that the ban could stifle innovation in the province.

"We understand the government's desire to ensure safety, but a blanket ban risks putting British Columbia behind in the development of this important technology," says a spokesperson for a self-driving vehicle start-up.


Debate Over Self-Driving Technology

The BC ban highlights a larger debate about the future of autonomous vehicles. While proponents point to potential benefits such as improved safety, reduced traffic congestion, and increased accessibility, and national policies like Canada's EV goals aim to accelerate adoption, critics raise concerns about liability, potential job losses in the transportation sector, and the ability of self-driving technology to handle complex driving situations.


BC Not Alone

British Columbia is not the only jurisdiction grappling with the regulation of self-driving vehicles. Several other provinces and states in both Canada and the U.S. are also working to develop clear legal and regulatory frameworks for this rapidly evolving technology, even as studies suggest B.C. may need to double its power output to fully electrify road transport.


The Road Ahead

The path forward for fully autonomous vehicles in BC depends on the government's ability to create a regulatory framework that balances safety considerations with fostering innovation, and align with clean-fuel investments like the province's hydrogen project to support zero-emission mobility.  When and how that framework will materialize remains unclear, leaving the future of self-driving cars in the province temporarily uncertain.

Bitcoin mining uses so much electricity that 1 city could curtail facility's power during heat waves

Medicine Hat Bitcoin Mining Facility drives massive electricity demand and energy use, leveraging natural gas and nearby wind power; Hut 8 touts economic growth, while critics cite carbon emissions, renewables integration, and climate impact.

 

Key Points

A Hut 8 project in Alberta that mines bitcoin at scale, consuming up to 60 MW and impacting energy and emissions.

✅ Consumes more than 60 MW, rivaling citywide electricity use

✅ Sited by natural gas plant; wind turbines nearby

✅ Economic gains vs. carbon emissions and climate risks

 

On the day of the grand opening of the largest bitcoin mining project in the country, the weather was partly cloudy and 15 C. On a Friday afternoon like this one, the new facility uses as much electricity as all of Medicine Hat, Alta., a city of more than 60,000 people and home to several large industrial plants.

The vast amount of electricity needed for bitcoin mining is why the city of Medicine Hat has championed the economic benefits of the project, while environmentalists say they are wary of the significant energy use.

Toronto-based Hut 8 has spent more than $100 million to develop the 4½-hectare site on the northern edge of the city. It has 56 shipping containers, each filled with 180 computer servers that digitally mine for bitcoin around the clock.

The company said it has already mined more than 3,300 bitcoins in Alberta, including at its much smaller site in Drumheller. On average, the Medicine Hat facility mines about 20 bitcoins per day. The value of bitcoin can fluctuate daily, but has sold recently for around $9,000.

The bitcoin mining facility is located right beside the city of Medicine Hat's new natural gas-fired power plant and four wind turbines are a short distance away. The bitcoin plant can consume more than 60 megawatts of power, more than 10 times more electricity used by any other facility in the city, according to the mayor.

That's why, in the event of a summer heat wave, the city has provisions in place to pull the plug on the electricity it provides to Hut 8, mirroring utility pauses on crypto loads seen elsewhere, so there won't be any blackouts for residents, according to the mayor.

Still, some say the bitcoin mining industry wastes far too much energy

"It's a huge magnitude when you talk about the carbon emissions," said Saeed Kaddoura, an analyst with the Pembina Institute, an environmental think-tank. "Moving forward, there needs to be some consideration on what the environmental impact of this is."

Medicine Hat owns its own natural gas and electricity generation and distribution businesses. The city leases the land to Hut 8 and the facility employs 40 full-time workers. Add up the economic benefits and the city of Medicine Hat will receive a significant financial boost from the new project, says Ted Clugston, the city's mayor.

Financial details of the city's deal with Hut 8 are not disclosed.

For more than a century, the city has attracted business by offering low-cost energy, and the mayor said this project is no different.

"They could have gone anywhere in the world and they chose Medicine Hat," said Clugston. "[Hut 8] is not here for renewable energy because it is not reliable. They need gas-fired generation and we have it in spades."

Environmental groups are concerned by the sheer amount of energy consumed by bitcoin mining, with some utilities warning they can't serve new energy-intensive customers right now, especially in places like Medicine Hat where most of the electricity is produced by fossil fuels.

The bitcoin system is designed, so only a limited number of the cryptocurrency can be mined everyday. Over time, as more miners compete for a decreasing number of available bitcoins, facilities will have to use more electricity compared to the amount of the cryptocurrency they collect.

"The way the bitcoin algorithm works is that it's designed to waste as much electricity as possible. And the more popular bitcoin becomes, the more electricity it wastes," said Keith Stewart, a spokesperson for Greenpeace.

Stewart questions whether natural gas should be used to produce a digital product.

"If you live in Alberta, you want to have heat and light, those types of things. I don't think bitcoin is a necessity of life for anyone," he said.

The CEO of Hut 8 completely disagrees, arguing the cryptocurrency is essential.  

"Bitcoin was created during the financial crisis. It has really served a purpose in terms of providing the opportunity for people who don't necessarily trust their government or their central banks," said Andrew Kiguel.
