Floating Solar at Fort Bragg delivers a 1 MW DoD-backed floatovoltaic array on Big Muddy Lake, boosting renewable energy, resilience, and efficiency via water cooling, with Duke Energy and Ameresco supporting backup power.

 

Key Points

A 1 MW floating PV array on Big Muddy Lake, built by the US Army to boost efficiency, resilience, and backup power.

✅ 1 MW array supplies backup power for training facilities.

✅ Water cooling improves panel efficiency and output.

✅ Partners: Duke Energy, Ameresco; DoD's first floating solar.

 

Floating solar had a moment in the spotlight over the weekend when the US Army unveiled a new solar plant sitting atop the Big Muddy Lake at Fort Bragg in North Carolina. It’s the first floating solar array deployed by the Department of Defense, and it’s part of a growing current of support in the US for “floatovoltaics” and other innovations like space-based solar research.

The army says its goal is to boost clean energy, support goals in the Biden solar plan for decarbonization, reduce greenhouse gas emissions, and give the nearby training facility a source of backup energy during power outages. The panels will be able to generate about one megawatt of electricity, which can typically power about 190 homes, and, when paired with solar batteries, enhance resilience during extended outages.

The installation, the largest in the US Southeast, is a big win for floatovoltaics, and projects like South Korea’s planned floating plant show global momentum for the technology, which has yet to make a big splash in the US. They only make up 2 percent of solar installations annually in the country, according to Duke Energy, which collaborated with Fort Bragg and the renewable energy company Ameresco on the project, even as US solar and storage growth accelerates nationwide.

Upfront costs for floating solar have typically been slightly more expensive than for its land-based counterparts. The panels essentially sit on a sort of raft that’s tethered to the bottom of the body of water. But floatovoltaics come with unique benefits, complementing emerging ocean and river power approaches in water-based energy. Hotter temperatures make it harder for solar panels to produce as much power from the same amount of sunshine. Luckily, sitting atop water has a cooling effect, which allows the panels to generate more electricity than panels on land. That makes floating solar more efficient and makes up for higher installation costs over time.

And while solar in general has already become the cheapest electricity source globally, it’s pretty land-hungry, so complementary options like wave energy are drawing interest worldwide. A solar farm might take up 20 times more land than a fossil fuel power plant to produce a gigawatt of electricity. Solar projects in the US have already run into conflict with some farmers who want to use the same land, for example, and with some conservationists worried about the impact on desert ecosystems.

GM Canada announces tentative deal for $1 billion electric vehicle plant in Ontario

GM Canada-Unifor EV Deal outlines a $1B plan to transform the CAMI plant in Ingersoll, Ontario, building BrightDrop EV600 delivery vans, boosting EV manufacturing, creating jobs, and securing future production with government-backed investment.

 

Key Points

A tentative $1B deal to retool CAMI for BrightDrop EV600 production, creating jobs and securing Canada's EV manufacturing.

✅ $1B to transform CAMI, Ingersoll, for BrightDrop EV600 vans

✅ Ratification vote set; Unifor Local 88 to review details

✅ Supports EV manufacturing, delivery logistics, and new jobs

 

GM Canada says it has reached a tentative deal with Unifor that if ratified will see it invest $1 billion to transform its CAMI plant in Ingersoll, Ont., to make commercial electric vehicles, aligning with GM's EV hiring plans across North America.

Unifor National President Jerry Dias says along with the significant investment the agreement will mean new products, new jobs amid Ontario's EV jobs boom and job security for workers.

Dias says in a statement that more details of the tentative deal will be presented to Unifor Local 88 members at an online ratification meeting scheduled for Sunday.

He says the results of the ratification vote are scheduled to be released on Monday.

Details of the agreement were not released Friday night.

A GM spokeswoman says in a statement that the plan is to build BrightDrop EV 600s -- an all-new GM business announced this week at the Consumer Electronics Show and part of EV assembly deals that put Canada in the race -- that will offer a cleaner way for delivery and logistics companies to move goods more efficiently.

Unifor said the contract, if ratified, will bring total investment negotiated by the union to nearly $6 billion after new agreements were ratified with General Motors, Ford, including Ford EV production plans, and Fiat Chrysler in 2020 that included support from the federal and Ontario governments, and parallel investments such as a Niagara Region battery plant bolstering the supply chain.

It said the Ford deal reached in September included $1.95 billion to bring battery electric vehicle production to Oakville via the Oakville EV deal and a new engine derivative to Windsor and the Fiat Chrysler agreement included more than $1.5 billion to build plug-in hybrid vehicles and battery electric vehicles.

Unifor said in November, General Motors agreed to a $1.3 billion dollar investment to bring 1,700 jobs to Oshawa, as Honda's Ontario battery investment signals wider sector momentum, plus more than $109 million to in-source new transmission work for the Corvette and support continued V8 engine production in St. Catharines.

N.W.T. will encourage more residents to drive electric vehicles

Northwest Territories EV Charging Corridor aims to link the Alberta boundary to Yellowknife with Level 3 fast chargers and Level 2 stations, boosting electric vehicle adoption in cold climates, cutting GHG emissions, supporting zero-emission targets.

 

Key Points

A planned corridor of Level 3 and Level 2 chargers linking Alberta and Yellowknife to boost EV uptake and cut GHGs.

✅ Level 3 fast charger funded for Behchoko by spring 2024.

✅ Up to 72 Level 2 chargers funded across N.W.T. communities.

✅ Supports Canada ZEV targets and reduces fuel use and CO2e.

 

Electric vehicles are a rare sight in Canada's North, with challenges such as frigid winter temperatures and limited infrastructure across remote regions.

The Northwest Territories is hoping to change that.

The territorial government plans to develop a vehicle-charging corridor between the Alberta boundary and Yellowknife to encourage more residents to buy electric vehicles to reduce their carbon footprint.

"There will soon be a time in which not having electric charging stations along the highway will be equivalent to not having gas stations," said Robert Sexton, director of energy with the territory’s Department of Infrastructure.

"Even though it does seem right now that there’s limited uptake of electric vehicles and some of the barriers seem sort of insurmountable, we have to plan to start doing this, because in five years' time, it’ll be too late."

The federal government has committed to a mandatory 100 per cent zero-emission vehicle sales target by 2035 for all new light-duty vehicles, though in Manitoba reaching EV targets is not smooth so progress may vary. It has set interim targets for at least 20 per cent of sales by 2026 and 60 per cent by 2030.

A study commissioned by the N.W.T. government forecasts electric vehicles could account for 2.9 to 11.3 per cent of all annual car and small truck sales in the territory in 2030.

The study estimates the planned charging corridor, alongside electric vehicle purchasing incentives, could reduce greenhouse gas emissions by between 260 and 1,016 tonnes of carbon dioxide equivalent in that year.

Sexton said it will likely take a few years before the charging corridor is complete. As a start, the territory recently awarded up to $480,000 to the Northwest Territories Power Corporation to install a Level 3 electric vehicle charger in Behchoko.

The N.W.T. government projects the charging station will reduce gasoline use by 61,000 litres and decrease carbon dioxide equivalent by up to 140 tonnes per year. It is scheduled to be complete by the spring of 2024.

The federal government earlier this month announced $414,000, along with $56,000 in territorial funding, to install up to 72 primarily Level 2 electric vehicle charges in public places, streets, multi-unit residential buildings, workplaces, and facilities with light-duty vehicle fleets in the N.W.T. by March 2024, while in New Brunswick new fast-charging stations are planned on the Trans-Canada.

In Yukon, the territory has pledged to develop electric vehicle infrastructure in all road-accessible communities by 2027. It has already installed 12 electric vehicle chargers with seven more planned, and in N.L. a fast-charging network signals early progress as well.

Just a few people in the N.W.T. currently own electric vehicles, and in Atlantic Canada EV adoption lags as well.

Patricia and Ken Wray in Hay River have owned a Tesla Model 3 for three years. Comparing added electricity costs with savings on gasoline, Patricia estimates they spend 60 per cent less to keep the Tesla running compared to a gas-powered vehicle.

“I don’t mind driving past the gas station,” she said.

Despite some initial hesitation about how the car would perform in the winter, Wray said she hasn’t had any issues with her Tesla when it’s -40 C, although it does take longer to charge. She added it “really hugs the road” in snowy and icy conditions.

“People in the North need to understand these cars are marvellous in the winter,” she said.

Wray said while she and her husband drive their Tesla regularly, it’s not feasible to drive long distances across the territory. As the number of electric vehicle charge stations increases across the N.W.T., however, that could change.

“I’m just very, very happy to hear that charging infrastructure is now starting to be put in place," she said.

Andrew Robinson with the YK Care Share Co-op is more skeptical about the potential success of a long-distance charging corridor. He said while government support for electric vehicles is positive, he believes there's a more immediate need to focus on uptake within N.W.T. communities. He pointed to local taxi services as an example.

"It’s a long stretch," he said of the drive from Alberta, where EVs are a hot topic, to Yellowknife. "It’s 17 hours of hardcore driving and when you throw in having to recharge, anything that makes that longer, people are not going to be really into that.”

The car sharing service, which has a 2016 Chevy Spark dubbed “Sparky,” states on its website that a Level 2 charger can usually recharge a vehicle within six to eight hours while a Level 3 charger takes approximately half an hour, as faster charging options roll out in B.C. and beyond.

Canada is a solar power laggard, this expert says

Canada Distributed Energy faces disruption as solar, smart grids, microgrids, and storage scale utility-scale renewables, challenging centralized utilities and accelerating decarbonization, grid modernization, and distributed generation across provinces like Alberta.

 

Key Points

Canada Distributed Energy shifts from centralized grids to local solar, wind, and storage for reliable low-carbon power.

✅ Morgan Solar and Enbridge launch Alberta Solar One, 13.7 MW.

✅ Optical films boost panel efficiency, lowering cost per watt.

✅ Strong utilities slow adoption of microgrids and smart grids.

 

By Nick Waddell

Disruption is coming to electricity generation but Canada has become a laggard when it comes to not just adoption of alternative energy sources but in moving to a more distributed model of electricity generation. That’s according to Mike Andrade, CEO of Morgan Solar, whose new solar project in conjunction with Enbridge has just come online in Alberta, a province known as a powerhouse for both green and fossil energy in Canada.

“There’s a lot of inertia to Canada’s electrical system and I don’t think that bodes well,” said Andrade, who spoke on BNN Bloomberg on Thursday. 

“Canada is one of the poorest places for uptake of solar, as NEB data on solar demand indicates,” Andrade said, “I believe a lot of it has to do with the fact that we have strong provincial utilities that have their mandates and their chosen technologies.”

Alberta Solar One, a 13.7 MW power facility near Lethbridge, Alberta, had its unveiling this week amid red-hot solar growth in Alberta that shows no sign of slowing. It’s a 36,500-panel farm constructed by Enbridge in a quick six-month turnaround as part of the power company’s pledge to become a carbon-free generator by 2050. Along with solar, Enbridge has made big investments in offshore and onshore wind farms in the United States, while also producing so-called green hydrogen at an Ontario plant.

Private company Morgan Solar considers the Alberta Solar One project as the first utility-scale validation of its technology, which uses optical films to redirect light onto photovoltaic cells to further power production. 

“We use an advanced modelling system and a variety of tools to design very simple optical systems that can be easily inserted into a panel,” Andrade said. “They cost less and bring down the cost per watt. It captures light that would otherwise miss the cells and so you get more power per cell area than any other commercial technology at this point.”

Like renewables in general, solar energy has been thrust into the spotlight as governments worldwide aim to make good on their climate change and emissions pledges, with analyses showing zero-emissions electricity by 2035 is possible in Canada, and convert power generation from fossil fuels to alternative sources. 

The market has paid attention, too, driving up values on renewable energy stocks across the board, including solar stocks, as provinces like Alberta explore selling renewable energy into broader markets. Last year, the Invesco Solar ETF, which tracks the MAC Global Solar Energy Index, soared 234 per cent, while Canadian companies with solar assets like Algonquin Power and Northland Power have been winners over the past few years.

Canadian cleantech companies involved in the solar power sector have also fared well, with names like UGE International (UGE International Stock Quote, Chart, News, Analyst. Financials TSXV:UGE), Aurora Solar and 5N Plus (5N Plus Stock Quote, Chart, News, Analysts, Financials TSX:VNP) having attracted investor attention of late.

Currently, part of the push in alternative energy involves the move from centralized to a more distributed picture of power generation, where solar panels, wind turbines and small modular nuclear reactors can operate close to or within sources of consumption like cities.

But Andrade says Canada has a lot of catching up to do on that front, especially as its current system seems devoted to maintaining the precedence of large, centralized power production — along with the utility companies that generate it.

“Canada is going to be left with this big, old fashioned hub and spoke model, and that’s increasingly going to be out-competed by a distributed grid, call them smart grids or micro grids,” Andrade said.

“That’s the future that solar is going to drive along with storage, and I personally don’t think Canada is prepared for it, not because we can’t do it but because regulatory and incumbency is holding us back from doing that,” he said.

“We pay our utilities, saying, ‘You invest capital and we’ll give you a fixed return on capital.’ Well, guess what? You’re going to get large, centralized capital projects which are going to get big central generation hub and spoke distribution,” Andrade said.

Ahead of the Canadian federal government’s tabling next week of its first budget in two years, many in the energy sector will be taking notes on the Liberal government’s investments in the so-called green recovery after the economic downturn, with renewable energy proponents hoping for further support, noting Alberta’s renewable energy surge could power thousands of jobs, to shift Canada’s resource sector away from fossil fuels.

By comparison, President Biden in the US recently unveiled his $2-billion infrastructure plan which put precedence on greening the country’s power grid, encouraging the adoption of electric vehicles and supporting renewable resource development, and Canadian studies suggest 2035 zero-emission power is practical and profitable as well across the national grid. 

On disruption in power generation, Andrade said there are parallels to be drawn from information technology, which has historically made a point of discarded outdated models along the way.

“I was at IBM, and they had the mainframe business and that got blown up. I also worked with Nortel and Celestica and they got blown up —and it wasn’t due to having better central hub and spoke systems. They got beat up by this distributed system,” Andrade said. 

“The same thing is going to happen here and the disruption is coming in electricity generation as well,” he said.

Opinion | Why Electric Mail Trucks Are the Way of the Future

USPS Electric Mail Trucks promise zero-emission delivery, lower lifecycle and maintenance costs, and cleaner air. Congressional funding in Build Back Better would modernize the EV fleet and expand charging infrastructure, improving public health nationwide.

 

Key Points

USPS Electric Mail Trucks are zero-emission delivery vehicles that cut costs, reduce pollution, and improve health.

✅ Lower lifetime fuel and maintenance costs vs gas trucks

✅ Cuts greenhouse gas and NOx emissions in communities

✅ Expands charging infrastructure via federal investments

 

The U.S. Postal Service faces serious challenges, with billions of dollars in annual losses and total mail volume continuing to decline. Meanwhile, Congress is constantly hamstringing the agency.

But now lawmakers have an opportunity to invest in the Postal Service in a way that would pay dividends for years to come: By electrifying the postal fleet.

Tucked inside the massive social spending and climate package lumbering through the Senate is money for new, cleaner postal delivery trucks. There’s a lot to like about electric postal trucks. They’d significantly improve Americans’ health while also slowing climate change. And it just makes sense for taxpayers over the long term; the Postal Service’s private sector competitors have already made similar investments, as EV adoption reaches an EV inflection point in the market. As Democrats weigh potential areas to cut in President Joe Biden’s Build Back Better plan, this is one provision that should escape the knife.

To call the U.S. Postal Service’s current vehicles “clunkers” would be an understatement. These often decades-old trucks are famous for having no airbags, no air conditioning and a nasty habit of catching fire. So the Postal Service’s recent decision to buy 165,000 replacement trucks is basically a no-brainer. But the main question is whether they will run on electricity or gasoline.

Electric vehicles are newer to the market and still carry a higher sticker price, as seen with electric bus adoption in many cities. But that higher price buys concrete benefits, like lower lifetime fuel and maintenance costs and huge reductions in pollution. Government demand for electric trucks will also push private markets to create better, cheaper vehicles, directly benefiting consumers. So while buying electric postal trucks may be somewhat more costly at first, over the long term, failing to do so could be far costlier.

At some level, this is a straightforward business decision that the Postal Service’s competitors have already made. For instance, Amazon has already deployed some of the 100,000 electric vans it recently ordered, and FedEx has promised a fully electric ground fleet by 2040, while nonprofit investment in electric trucks is accelerating electrification at major ports. In a couple of decades, the Postal Service could be the only carrier still driving dirty gas guzzlers, buying expensive fuel and paying the higher maintenance costs that combustion engines routinely require. Consumers could flock to greener competitors.

Beyond these business advantages, zero-emission vehicles carry other big benefits for the public. The Postal Service recently calculated some of these benefits by estimating the climate harms that going all-electric would avoid, benefits that persist even where electricity generation still includes fossil-generated electricity in nearby grids. Its findings were telling: A fully electric fleet would prevent millions or tens of millions of dollars’ worth of climate-change-related harms to property and human health each year of the trucks’ lifetimes (and this is probably a considerable underestimate). The world leaders that recently gathered at the global climate summit in Glasgow encouraged exactly this type of transition toward low-carbon technologies.

A cleaner postal fleet would benefit Americans in many other important ways. In addition to warming the planet, tailpipe pollutants can have dire health consequences for the people who breathe in the fumes. Mail trucks traverse virtually every neighborhood in the country and often must idle in residential areas, so we all benefit when they stop emitting. And these localized harms are not distributed equally. Some parts of the country — too often, low-income communities of color — already have poor air quality. Removing pollution from dirty mail trucks will especially help these overburdened and underserved populations.

The government’s purchasing power also routinely inspires companies to devise better and cheaper ways to do business. Investments in aerospace technologies, for instance, have spilled over into consumer innovations, giving us GPS technologies and faster, more fuel-efficient passenger jets. Bulk demand for cleaner trucks could inspire similar innovations as companies clamor for government contracts, meaning we all could get cheaper and better green products like car batteries, and the American EV boom could further accelerate those gains.

Additionally, because postal trucks are virtually everywhere in the country, if they go electric, that would mean more charging stations and grid updates everywhere too, and better utility planning for truck fleets to ensure reliable service. Suddenly, that long road trip that discourages many would-be electric car buyers may be simpler, which could boost electric vehicle adoption.

White House climate adviser Gina McCarthy talks with EVgo CEO Cathy Zoi before the start of an event near an EVgo electric car charging station.
ENERGY

The case for electrifying the postal fleet is strong from both a business and a social standpoint. Indeed, even Postmaster General Louis DeJoy, who was appointed during the Trump administration, supports it. But getting there is not so simple. Most private businesses could just borrow the money they need for this investment and pay it back with the long-term savings they would enjoy. But not the Postal Service. Thanks to its byzantine funding structure, it cannot afford electric trucks’ upfront costs unless Congress either provides the money or lets it borrow more. This is the primary reason it has not committed to making more than 10 percent of its fleet electric.

And that returns us to the Build Back Better legislation. The version passed by the House sets aside $7 billion to help the Postal Service buy electric mail trucks — enough to electrify the vast majority of its fleet by the end of the decade.

Biden has made expanding the use of electric vehicles a top priority, setting an ambitious goal of 100 percent zero-emission federal vehicle acquisitions by 2035, and new EPA emission limits aim to accelerate EV adoption. But Sen. Joe Manchin has expressed resistance to some of the climate-related subsidies in the legislation and is also eager to keep costs down. This provision, however, is worthy of the West Virginia Democrat’s support.

Most Americans would see — and benefit from — these trucks on a daily basis. And for an operation that got its start under Benjamin Franklin, it’s a crucial way to keep the Postal Service relevant.

What cities can learn from the biggest battery-powered electric bus fleet in North America

Canadian Electric Bus Fleet leads North America as Toronto's TTC deploys 59 battery-electric, zero-emission buses, advancing public transit decarbonization with charging infrastructure, federal funding, lower maintenance, and lifecycle cost savings for a low-carbon urban future.

 

Key Points

Canada's leading battery-electric transit push, led by Toronto's TTC, scaling zero-emission buses and charging.

✅ Largest battery-electric bus fleet in North America

✅ TTC trials BYD, New Flyer, Proterra for range and reliability

✅ Charging infrastructure, funding, and specs drive 2040 zero-emissions

 

The largest battery-powered electric bus fleet in North America is Canadian. Toronto's transit system is now running 59 electric buses from three suppliers, and Edmonton's first electric bus is now on the road as well. And Canadian pioneers such as Toronto offer lessons for other transit systems aiming to transition to greener fleets for the low-carbon economy of the future.

Diesel buses are some of the noisier, more polluting vehicles on urban roads. Going electric could have big benefits, even though 18% of Canada's 2019 electricity from fossil fuels remains a factor.

Emissions reductions are the main reason the federal government aims to add 5,000 electric buses to Canada's transit and school fleets by the end of 2024. New funding announced this week as part of the government's fall fiscal update could also give programs to electrify transit systems a boost.

"You are seeing huge movement towards all-electric," said Bem Case, the Toronto Transit Commission's head of vehicle programs. "I think all of the transit agencies are starting to see what we're seeing ... the broader benefits."

While Vancouver has been running electric trolley buses (more than 200, in fact), many cities (including Vancouver) are now switching their diesel buses to battery-electric buses in Metro Vancouver that don't require overhead wires and can run on regular bus routes.

The TTC got approval from its board to buy its first 30 battery-electric buses in November 2017. Its plan is to have a zero-emissions fleet by 2040.

That's a crucial part of Toronto's plan to meet its 2050 greenhouse gas targets, which requires 100 per cent of vehicles to transition to low-carbon energy by then.

But Case said the transition can't happen overnight. 


Finding the right bus
For one thing, just finding the right bus isn't easy.

"There's no bus, by any manufacturer, that's been in service for the entire life of a bus, which is 12 years," Case said.

"And so really, until then, we don't have enough experience, nor does anyone else in the industry, have enough experience to commit to an all-electric fleet immediately."

In fact, Case said, there are only three manufacturers that make suitable long-range buses — the kind needed in a city the size of Toronto.

Having never bought electric buses before, the city had no specifications for what it needed in an electric bus, so it decided to try all three suppliers: Winnipeg-based New Flyer; BYD, which is headquartered in Shenzhen, China, but built the TTC buses at its Newmarket, Ont. facility; and California-based Proterra.

They all had their strengths and weaknesses, based on their backgrounds as a traditional non-electric bus manufacturer, a battery maker and a vehicle technology and design startup, respectively.

"Each bus type has its own potential challenges." Case said all three manufacturers are working to resolve any adoption challenges as quickly as possible.

But the biggest challenge of all, Case said, is getting the infrastructure in place. 

"There's no playbook, really, for implementing charging infrastructure," he said.

Each bus type needed their own chargers, in some cases using different types of current. Each type has been installed in a different garage in partnership with local utility Toronto Hydro.

Buying and installing them represented about $70 million, or about half the cost of acquiring Toronto's first 60 electric buses. The $140 million project was funded by the federal Public Transit Infrastructure Fund.

Case said it takes about three hours to charge a battery that has been fully depleted. To maximize use of the bus, it's typically put on a long route in the morning, covering 200 to 250 kilometres. Then it's partially charged and put on a shorter run in the late afternoon.

"That way we get as much mileage on the buses as we can."


Cost and reliability?
Besides the infrastructure cost of chargers, each electric bus can cost $200,000 to $500,000 more per bus than an average $750,000 diesel bus. 

Case acknowledges that is "significantly" more expensive, but it is offset by fuel savings over time, as electricity costs are cheaper. Because the electric buses have fewer parts than diesel buses, maintenance costs are also about 25 per cent lower and the buses are expected to be more reliable.

As with many new technologies, the cost of electric buses is also falling over time.

Case expects they will eventually get to the point where the total life-cycle cost of an electric and a diesel bus are comparable, and the electric bus may even save money in the long run.

As of this fall, all but one of the 60 new electric buses have been put into service. The last one is expected to hit the road in early December.

Summer testing showed that air conditioning the buses reduced the battery capacity by about 15 per cent. 

But the TTC needs to see how much of the battery capacity is consumed by heating in winter, at least when the temperature is above 5 C. Below that, a diesel-powered heater kicks in.

Once testing is complete, the TTC plans to develop specifications for its electric bus fleet and order 300 more in 2023, for delivery between 2023 and 2025.


Potential benefits
Even with some diesel heating, the TTC estimates electric buses reduce fuel usage by 70 to 80 per cent. If its whole fleet were switched to electric buses, it could save $50 million to $70 million in fuel a year and 150 tonnes of greenhouse gases per bus per year, or 340,000 tonnes for the entire fleet.

Other than greenhouse gases, electric buses also generate fewer emissions of other pollutants. They're also quieter, creating a more comfortable urban environment for pedestrians and cyclists.

But the benefits could potentially go far beyond the local city.

"If the public agencies start electrifying their fleet and their service is very demanding, I think they'll demonstrate to the broader transportation industry that it is possible," Case said.

"And that's where you'll get the real gains for the environment."

Alex Milovanoff, a postdoctoral researcher in the University of Toronto's department of civil engineering, did a U of T EV study that suggested electrified transit has a crucial role to play in the low-carbon economy of the future.

His calculations show that 90 per cent of U.S. passenger vehicles — 300 million — would need to be electric by 2050 to reach targets under the global Paris Agreement to fight climate change.

And that would put a huge strain on resources, including both the mining of metals, such as lithium and cobalt, that are used in electric vehicle batteries and the electrical grid itself.

A better solution, he showed, was combining the transition to electric vehicles with a reduction in the number of private vehicles, and higher usage of transit, cycling and walking.

"Then that becomes a feasible picture," he said.

What's needed to make the transition
But in order to make that happen, governments need to make investments and navigate the 2035 EV mandate debate on timelines, he added.

That includes subsidies for buying electric buses and building charging stations so transit agencies don't need to make fares too high. But it also includes more general improvements to the range and reliability of transit infrastructure.

"Electrifying the bus fleet is only efficient if we have a large public transit fleet and if we have many buses on the road and if people take them," Milovanoff said.

In its fall economic update on Monday, the federal government announced $150 million over three years to speed up the installation of zero-emission vehicle infrastructure.

Josipa Petrunic, CEO of the Canadian Urban Transit Research and Innovation Consortium, a non-profit organization focused on zero-carbon mobility and transportation, said that in the past, similar funding has paid for high-powered charging systems for transit systems in B.C. and Ontario. But that's only a small part of what's needed, she said.

"Infrastructure Canada needs to come to the table with the cash for the buses and the whole rest of the system."

She said funding is needed for:

Feasibility studies to figure out how many and what kinds of buses are needed for different routes in different transit systems.

Targets and incentives to motivate transit systems to make the switch.

Incentives to encourage Canadian procurement to build the industry in Canada.

Technology to collect and share data on the performance of electric vehicles so transit systems can make the best-possible decisions to meet the needs of their riders.

Petrunic said that a positive side-effect of electrifying transit systems is that the infrastructure can support, in addition to buses, electric trucks for moving freight.

"It's not a lot given that we have 15,000 buses out there in the transit fleet," she said.

"But we should be able to get a lot further ahead if we match the city commitments to zero emissions with federal and provincial funding for jobs creating zero-emissions technologies."

SEA To Convert 10,000 US School Buses To Electricity

SEA Electric school bus conversions bring EV electrification to Type A and Type C fleets, adding V2G, smart charging, battery packs, and zero-emissions performance while extending service life with cost-effective retrofits across US school districts.

 

Key Points

Retrofit EV drivetrains for Type A and C buses, adding V2G and smart charging to cut emissions and costs.

✅ Converts 10,000 Type A and C school buses over five years

✅ Adds V2G, smart charging, and fleet battery management

✅ Cuts diesel fumes, maintenance, and total cost of ownership

 

Converting a Porsche 356C to electric power is a challenge. There’s precious little room for batteries, converters, and such. But converting a school bus? That’s as easy as falling off a log, even if adoption challenges persist in the sector today. A bus has acres of space for batteries and the electronics need to power an electric motor.

One of the dumbest ideas human beings ever came up with was sealing school children inside a diesel powered bus for the trip to and from school. Check out our recent article on the impact of fossil fuel pollution on the human body. Among other things, fine particulates in the exhaust gases of an internal combustion engine have been shown to lower cognitive function. Whose bright idea was it to make school kids walk through a cloud of diesel fumes twice a day when those same fumes make it harder for them to learn?

Help may be on the way, as lessons from the largest e-bus fleet offer guidance for scaling. SEA Electric, a provider of electric commercial vehicles originally from Australia and now based in Los Angeles has stuck a deal with Midwest Transit Equipment to convert 10,000 existing school buses to electric vehicles over the next five years. Midwest will provide the buses to be converted to the SEA Drive propulsion system. SEA Electric will complete the conversions using its “extensive network of up-fitting partners,” Nick Casas, vice president of sales and marketing for SEA Electric, says in a press release.

After the conversions are completed, the electric buses will have vehicle to grid (V2G) capability that will allow them to help balance the local electrical grid, where state power grids face new demands, and “smart charge” when electricity prices are lowest. The school buses to be converted are of the US school bus class Type A  or Type C. Type A is the smallest US school bus with a length of 6 to 7.5 metres and is based on a van chassis. The traditional Type C school buses are built on truck architectures.

SEA Electric says that the conversion will extend the life of the buses by more than ten years, with early deployments like B.C. electric school buses demonstrating real-world performance, and that two to three converted buses can be had for the price of one new electric bus. Mike Menyhart, chief strategy officer at SEA Electric says, “The secondary use of school buses fitted with all-electric drivetrains makes a lot of sense. It keeps costs down, opens up considerable availability, creates green jobs right here in the US, all while making a difference in the environment and the health of the communities we serve.”

According to John McKinney, CEO of Midwest Transport Equipment, the partnership with SEA Electric will ensure that it can respond more quickly to customers’ needs as policies like California's 2035 school-bus mandate accelerate demand in key markets. “As the industry moves towards zero emissions we are positioned well with our SEA Electric partnership to be a leader of the electrification movement.”

According to Nick Casas, SEA Electric will plans to expand it operations to the UK soon, and intends to do business in six countries in Europe, including Germany, in the years to come. SEA says it will have delivered more than 500 electric commercial vehicles in 2021 and plans to put more than 15,000 electric vehicles on the road by the end of 2023. Just a few weeks ago, SEA Electric announced an order for 1,150 electric trucks based on the Toyota Hino cargo van for the GATR company of California, highlighting truck fleet power needs that utilities must plan for today.

Electric school buses make so much sense. No fumes to fog young brains, lower maintenance costs, and lower fuel costs are all pluses, especially as bus depot charging hubs scale across markets, adding resilience. Extending the service life of an existing bus by a decade will obviously pay big dividends for school bus fleet operators like MTE. It’s a win/win/win situation for all concerned, with the possible exception of diesel mechanics. But the upside there is they can be retrained in how to maintain electric vehicles, a skill that will be in increasing demand as the EV revolution picks up speed.
