Electric Fleet Grid Planning aligns utilities, charging infrastructure, distribution upgrades, and substation capacity to meet megawatt loads from medium- and heavy-duty EV trucks and buses, enabling managed charging, storage, and corridor fast charging.

Key Points

A utility plan to upgrade feeders and substations for EV fleets, coordinating charging, storage, and load management.

✅ Plans distribution, substation, and transformer upgrades

✅ Supports managed charging and on-site storage

✅ Aligns utility investment with fleet adoption timelines

As more electric buses and trucks enter the market, future fleets will require a lot of electricity for charging and will challenge state power grids over time. While some utilities in California and elsewhere are planning for an increase in power demand, many have yet to do so and need to get started.

This issue is critical, because freight trucks emit more than one-quarter of all vehicle emissions. Recent product developments offer growing opportunities to electrify trucks and buses and slash their emissions (see our recent white paper). And just last week, a group of 15 states plus D.C. announced plans to fully electrify truck sales by 2050. Utilities will need to be ready to power electric fleets.

Electric truck fleets need substantial power
Power for trucks and buses is generally more of an issue than for cars because trucks typically have larger batteries and because trucks and buses are often parts of fleets with many vehicles that charge at the same location. For example, a Tesla Model 3 battery stores 54-75 kWh; a Proterra transit bus battery stores 220-660 kWh. In Amsterdam, a 100-bus transit fleet is powered by a set of slow and fast chargers that together have a peak load of 13 MW (megawatts). This is equivalent to the power used by a typical large factory. And they are thinking of expanding the fleet to 250 buses.

California utilities are finding that grid capacity is often adequate in the short term, but that upgrade needs likely will grow in the medium term.
Many other fleets also will need a lot of "juice." For example, a rough estimate of the power needed to serve a fleet of 200 delivery vans at an Amazon fulfillment center is about 4 MW. And for electric 18-wheelers, chargers may need up to 2 MW of power each; a recent proposal calls for charging stations every 100 miles along the U.S. West Coast’s I-5 corridor, highlighting concerns about EVs and the grid as each site targets a peak load of 23.5 MW.

Utilities need distribution planning
These examples show the need for more power at a given site than most utilities can provide without planning and investment. Meeting these needs often will require changes to primary and secondary power distribution systems (feeders that deliver power to distribution transformers and to end customers) and substation upgrades. For large loads, a new substation may be needed. A paper recently released by the California Electric Transportation Coalition estimates that for loads over 5 MW, distribution system and substation upgrades will be needed most of the time. According to the paper, typical utility costs are $1 million to $9 million for substation upgrades, $150,000 to $6 million for primary distribution upgrades, and $5,000 to $100,000 for secondary distribution upgrades. Similarly, Black and Veatch, in a paper on Electric Fleets, also provides some general guidance, shown in the table below, while recognizing that each site is unique.

California policy pushes utilities toward planning
In California, state agencies and a statewide effort called CALSTART have been funding demonstration projects and vehicle and charger purchases for several years to support grid stability as electrification ramps up. The California Air Resources Board voted in June to phase in zero-emission requirements for truck sales, mandating that, beginning in 2024, manufacturers must increase their zero-emission truck sales to 30-50 percent by 2030 and 40-75 percent by 2035. By 2035, more than 300,000 trucks will be zero-emission vehicles.

California utilities operate programs that work with fleet owners to install the necessary infrastructure for electric vehicle fleets. For example, Southern California Edison operates the Charge Ready Transport program for medium- and heavy-duty fleets. Normally, when customers request new or upgraded service from the utility, there are fees associated with the new upgrade. With Charge Ready, the utility generally pays these costs, and it will sometimes pay half the cost of chargers; the customer is responsible for the other half and for charger installation costs. Sites with at least two electric vehicles are eligible, but program managers report that at least five vehicles are often needed for the economics to make sense for the utility.

One way to do this is to develop and implement a phased plan, with some components sized for future planned growth and other components added as needed. Southern California Edison, for example, has 24 commitments so far, and has a five-year goal of 870 sites, with an average of 10 chargers per site. The utility notes that one charger usually can serve several vehicles and that cycling of charging, some storage, and other load management techniques through better grid coordination can reduce capacity needs (a nominal 10 MW load often can be reduced below 5 MW).

Through this program, utility representatives are regularly talking with fleet operators, and they can use these discussions to help identify needed upgrades to the utility grid. For example, California transit agencies are doing the planning to meet a California Air Resources Board mandate for 100 percent electric or fuel cell buses by 2040; utilities are talking with the agencies and their consultants as part of this process. California utilities are finding that grid capacity is often adequate in the short term, but that upgrade needs likely will grow in the medium term (seven to 10 years out). They can manage grid needs with good planning (school buses generally can be charged overnight and don’t need fast chargers), load management techniques and some energy storage to address peak needs.

Customer conversations drive planning elsewhere
We also spoke with a northeastern utility (wishing to be unnamed) that has been talking with customers about many issues, including fleets. It has used these discussions to identify a few areas where grid upgrades might be needed if fleets electrify. It is factoring these findings into a broader grid-planning effort underway that is driven by multiple needs, including fleets. Even within an integrated planning effort, this utility is struggling with the question of when to take action to prepare the electric system for fleet electrification: Should it act on state or federal policy? Should it act when the specific customer request is submitted, or is there something in between? Recognizing that any option has scheduling and cost allocation implications, it notes that there are no easy answers.

Many utilities need to start paying attention
As part of our research, we also talked with several other utilities and found that they have not yet looked at how fleets might relate to grid planning. However, several of these companies are developing plans to look into these issues in the next year. We also talked with a major truck manufacturer, also wishing to remain unnamed, that views grid limitations as a key obstacle to truck electrification. 

Based on these cases, it appears that fleet electrification can have a substantial impact on electric grids and that, while these impacts are small at present, they likely will grow over time. Fleet owners, electric utilities, and utility regulators need to start planning for these impacts now, so that grid improvements can be made steadily as electric fleets grow. Fleet and grid planning should happen in parallel, so that grid upgrades do not happen sooner or later than needed but are in place when needed, including the move toward a much bigger grid as EV adoption accelerates. These grid impacts can be managed and planned for, but the time to begin this planning is now.

Solar has become the EU’s main source of electricity, marking a historic turning point in Europe’s energy mix as solar power surpasses nuclear and wind, accelerates renewable expansion, lowers carbon emissions, and strengthens the EU’s clean energy transition.

Why has Solar Become the EU’s Main Source of Electricity?

Solar has become the EU’s primary source of electricity due to rapid solar expansion, lower installation costs, and robust clean energy policies, which have boosted generation, reduced fossil fuel dependence, and accelerated Europe’s transition toward sustainability.

✅ Surging solar capacity and falling costs

✅ Policy support for renewable energy growth

✅ Reduced reliance on oil, gas, and coal

Tesla Battery Day Innovations detail larger cylindrical EV cells with higher energy density, greater power, longer range, cobalt-free chemistry, automated manufacturing, battery recycling, and lower cost per kWh to enable an affordable electric car.

Key Points

Tesla Battery Day innovations are new EV cells and methods to cut costs, extend range, and scale production.

✅ Larger cylindrical cells: 5x energy, 6x power, 16% more range

✅ Automation and recycling to cut battery cost per kWh

✅ Near-zero cobalt chemistry, in-house cell factories worldwide

Elon Musk described a new generation of electric vehicle batteries that will be more powerful, longer lasting, and half as expensive as the company’s current cells at Tesla’s “Battery Day”.

Tesla’s new larger cylindrical cells will provide five times more energy, six times more power and 16% greater driving range, Musk said, adding that full production is about three years away.

“We do not have an affordable car. That’s something we will have in the future. But we’ve got to get the cost of batteries down,” Musk said.

To help reduce cost, Musk said Tesla planned to recycle battery cells at its Nevada “gigafactory,” while reducing cobalt – one of the most expensive battery materials – to virtually zero. It also plans to manufacture its own battery cells at several highly automated factories around the world.

The automaker plans to produce the new cells via a highly automated, continuous-motion assembly process, according to Drew Baglino, Tesla senior vice-president of powertrain and energy engineering, a contrast with GM and Ford battery strategies in the broader market today.

Speaking at the event, during which Musk outlined plans to cut costs and reiterated a huge future for Tesla's energy business during the presentation, the CEO acknowledged that Tesla does not have its new battery design and manufacturing process fully complete.

The automaker’s shares slipped as Musk forecast the change could take three years. Tesla has frequently missed production targets.

Tesla expects to eventually be able to build as many as 20m electric vehicles a year, aligning with within-a-decade EV adoption outlooks cited by analysts. This year, the entire auto industry expects to deliver 80m cars globally.

At the opening of the event, which drew over 270,000 online viewers, Musk walked on stage as about 240 shareholders – each sitting in a Tesla Model 3 in the company parking lot – honked their car horns in approval.

As automakers shift from horsepower to kilowatts to comply with stricter environmental regulations amid an age of electric cars that appears ahead of schedule, investors are looking for evidence that Tesla can increase its lead in electrification technology over legacy automakers who generate most of their sales and profits from combustion-engine vehicles.

While average electric vehicle prices have decreased in recent years thanks to changes in battery composition and evidence that they are better for the planet and household budgets, they are still more expensive than conventional cars, with the battery estimated to make up a quarter to a third of an electric vehicle’s cost.

Some researchers estimate that price parity, or the point at which electric vehicles are equal in value to internal combustion cars, is reached when battery packs cost $100 per kilowatt hour (kWh), a potential inflection point for mass adoption.

Tesla’s battery packs cost $156 per kWh in 2019, according to electric vehicle consulting firm Cairn Energy Research Advisors, with some studies noting that EVs save money over time for consumers, which would put the cost of a 90-kWh pack at around $14,000.

Tesla is also building its own cell manufacturing facility at its new factory in Germany in addition to the new plant in Fremont.

Ontario EV V2G Pilots enable bi-directional charging, backup power, and grid services with IESO, Toronto Hydro, and Hydro One, linking energy storage, solar, blockchain apps, and demand response incentives for smarter electrification.

Key Points

Ontario EV V2G pilots test bidirectional charging and backup power to support grid services with apps and incentives.

✅ Tests Nissan Leaf V2H backup with Hydro One and Peak Power.

✅ Integrates solar, storage, blockchain apps via Sky Energy and partners.

✅ Pilots demand response apps in Toronto and Waterloo utilities.

Electric vehicle owners in Ontario may one day be able to use the electricity in their EVs instead of loud diesel or gas generators to provide emergency power during blackouts. They could potentially also sell back energy to the grid when needed. Both are key areas of focus for new pilot projects announced this week by Ontario’s electricity grid operator and partners that include Toronto Hydro and Ontario Hydro.

Three projects announced this week will test the bi-directional power capabilities of current EVs and the grid, all partially funded by the Independent Electricity System Operator (IESO) of Ontario, with their announcement in Toronto also attended by Ontario Energy Minister Todd Smith.

The first project is with Hydro One Networks and Peak Power, which will use up to 10 privately owned Nissan Leafs to test what is needed technically to support owners using their cars for vehicle-to-building charging during power outages. It will also study what type of financial incentives will convince EV owners to provide backup power for other users, and therefore the grid.

A second pilot program with solar specialist Sky Energy and engineering firm Hero Energy will study EVs, energy storage, and solar panels to further examine how consumers with potentially more power to offer the grid could do it securely, in part using blockchain technology. York University and Volta Research are other partners in the program, which has already produced an app that can help drivers choose when and how much power to provide the grid — if any.

The third program is with local utilities in Toronto and Waterloo, Ont., and will test a secure digital app that helps EV drivers see the current demands on the grid through improved grid coordination mechanisms, and potentially price an incentive to EV drivers not to charge their vehicles for a few hours. Drivers could also be actively further paid to provide some of the charge currently in their vehicle back to the grid.

It all adds up to $2.7 million in program funding from IESO ($1.1 million) and the associated partners.

“An EV charged in Ontario produces roughly three per cent of emissions of a gas fuelled car,” said IESO’s Carla Nell, vice-president of corporate relations and innovation at the announcement near Peak Power chargers in downtown Toronto. “We know that Ontario consumers are buying EVs, and expected to increase tenfold — so we have to support electrification.”

If these types of programs sound familiar, it may be because utilities in Ontario have been testing such vehicle-to-grid technologies soon after affordable EVs became available in the fall of 2011. One such program was run by PowerStream, now the called Alectra, and headed by Neetika Sathe, who is now Alectra’s vice-president of its Green Energy and Technology (GRE&T) Centre in Guelph, Ont.

The difference between now and those tests in the mid-2010s is that the upcoming wave of EV sales can be clearly seen on the horizon, and California's grid stability work shows how EVs can play a larger role.

“We can see the tsunami now,” she said, noting that cost parity between EVs and gas vehicles is likely four or five years away — without government incentives, she stressed. “Now it’s not a question of if, it’s a question of when — and that when has received much more clarity on it.”

Sathe sees a benefit in studying all these types of bi-directional power-flowing scenarios, but notes that they are future scenarios for years in the future, especially since bi-directional charging equipment — and the vehicles with this capability — are pricey, and largely still not here. What she believes is much closer is the ability to automatically communicate what the grid needs with EV drivers, as Nova Scotia Power pilots integration, and how they could possibly help. For a price, of course.

“If I can set up a system that says ‘oh, the grid is stressed, can you not charge for the next two hours? And here’s what we’ll offer to you for that,’ that’s closer to low-hanging fruit,” she said, noting that Alectra is currently testing out such systems. “Think of it the same way as offering your car for Uber, or a room on Airbnb.”

U.S. EV Sales Growth reflects rising consumer demand, expanding market share, new tax credits, and robust charging infrastructure, as automakers boost output and quarterly sales under the Inflation Reduction Act drive adoption across states.

Key Points

It is the rise in U.S. EV sales and market share, driven by incentives, charging growth, and automaker investment.

✅ Quarterly EV sales and share have risen since Q3 2021.

✅ Share topped 10% in Q3 2023, with states far above.

✅ IRA credits and chargers lower costs and boost adoption.

Contrary to any skepticism, the demand for electric vehicles (EVs) in the United States is not dwindling. Data from the Alliance for Automotive Innovation highlights a significant and ongoing increase in EV sales from 2021 through the third quarter of 2023. An upward trend in quarterly sales (depicted as bars on the left axis) and EV sales shares (illustrated by the red line on the right axis) is evident. Sales surged from about 125,000 in Q1 2021 to 185,000 in Q4 2021, and from around 300,000 in Q1 2023 to 375,000 by Q3 2023. Notably, by Q3 2023, annual U.S. EV sales exceeded 1 million for the first time, a milestone often cited as the tipping point for mass adoption in the U.S., marking a 58% increase over the same period in 2022.

EV sales have shown consistent quarterly growth since Q3 2021, and the proportion of EVs in total light-duty vehicle sales is also on the rise. EVs’ share of new sales increased from roughly 3% in Q1 2021 to about 7% in 2022, and further to over 10% in Q3 2023, though they are still behind gas cars in overall market share, for now. For context, according to the U.S. Environmental Protection Agency’s Automotive Trends Report, EVs have reached a 10% market share more quickly than conventional hybrids without a plug, which took about 25 years.

State-level data also indicates that several states exceed national averages in EV sales. California, for example, saw EVs comprising nearly 27% of sales through September 2023, even as a brief Q1 2024 market share dip has been noted nationally. Additionally, 12 states plus the District of Columbia had EV sales shares between 10% and 20% through Q3 2023.

EV sales data by automaker reveal that most companies sold more EVs in Q2 or Q3 2023 than in any previous quarter, mirroring global growth that went from zero to 2 million in five years. Except for Ford, each automaker sold more EVs in the first three quarters of 2023 than in all of 2022. EV sales in Q3 2023 notably increased compared to Q3 2022 for companies like BMW, Tesla, and Volkswagen.

Despite some production scalebacks by Ford and General Motors, these companies, along with others, remain dedicated to an electric future and expect to sell more EVs than ever. The growing consumer interest in EVs is also reflected in recent surveys by McKinsey, J.D. Power, and Consumer Reports, and echoed in Europe where the share of electric cars grew during lockdown months, showing an increasing intent to purchase EVs and a declining interest in gasoline vehicles.

Furthermore, the Inflation Reduction Act of 2022 introduces new tax credits, potentially making EVs more affordable than gasoline counterparts. Investments in charging infrastructure are also expected to increase, especially as EV adoption could drive a 38% rise in U.S. electricity demand, with over $21 billion allocated to boost public chargers from around 160,000 in 2023 to nearly 1 million by 2030.

The shift to EVs is crucial for reducing climate pollution, enhancing public health, and generating economic benefits and jobs, and by 2021 plug-in vehicles had already traveled 19 billion miles on electricity, underscoring real-world progress toward these goals. The current data and trends indicate a robust and positive future for EVs in the U.S., reinforcing the need for strong standards to further encourage investment and consumer confidence in electric vehicles.

Clean Energy Transition spans hydrogen strategies, offshore wind and undersea cables, decarbonization pledges, and net-zero targets, including green vs blue hydrogen, carbon capture, sustainable aviation fuel, forest conservation, and wetland protection in Canadian policy.

Key Points

A shift to low-carbon systems via hydrogen, renewables, net-zero policies, carbon capture, and conservation.

✅ Hydrogen pathways: green vs blue with carbon capture

✅ Grid expansion: offshore wind and undersea cables in Japan

✅ Policy and corporate moves: net-zero, SAF, forests, wetlands

The Canadian federal government is set to sign a new agreement with Germany to strategize on a “clean-energy transition,” with clean hydrogen in Canada expected to be a key player the Globe and Mail reports.

“Germany is probably the world’s most interesting market for hydrogen right now, and Canada is potentially a very big power in its production,” Sabine Sparwasser, Germany’s ambassador to Canada, said in an interview.

However, some friction is expected as Natural Resources Minister Seamus O’Regan has been endorsing “blue” hydrogen, while Germany has been more interested in “green” hydrogen. The former hydrogen is produced from natural gas or other fossil fuels, while simultaneously “using carbon-capture technology to minimize emissions from the process.” In contrast, “green” hydrogen, is manufactured from non-fossil fuel sources, and cleaning up Canada's electricity is critical to meeting climate pledges.

“How the focus on blue hydrogen will be aligned with Canada’s goal of reaching climate neutrality by 2050 is not spelled out in detail,” says an executive summary of the report by the Berlin-based think tank and consultancy Adelphi. “As a result, the strategy seems to be more of a vision for the future of those provinces with large fossil fuel resources.”

According to an IEA report Canada will need more electricity to hit net-zero, underscoring the strategy questions.

Internationally

Japan is in talks to develop undersea cables that would bring offshore wind energy to Tokyo and the Kansai region, as the country hopes to more than quadrable its wind capacity from 10 gigawatts in 2030 to 45 gigawatts in 2040. The construction of the cables would cost about US$9.2 billion.

In Western Canada, bridging the electricity gap between Alberta and B.C. makes similar climate sense, proponents argue.

Approximately 80 per cent of that offshore power is expected to be built in Hokkaido, Tohoku, and Kyushu regions. The project is part of the country’s pledge to achieve decarbonization by 2050, according to BNN Bloomberg.

Meanwhile, Russia is falling behind in the world’s transition to clean energy.

“What’s the alternative? Russia can’t be an exporter of clean energy, that path isn’t open for us,” says Konstantin Simonov, director of the National Energy Security Fund, a Moscow consultancy whose clients include major oil and gas companies. “We can’t just swap fossil fuel production for clean energy production, because we don’t have any technology of our own.” Ultimately, natural gas will always be cheaper than renewable energy in Russia, Simonov added. This story also from BNN Bloomberg.

Finally, New Zealand’s Tilt Renewables Ltd., an electricity company, has announced it would be acquired by Powering Australian Renewables (PowAR) for NZ$2.94 billion (US$2.10 billion). PowAR is Australia’s largest owner of wind and solar energy, and the deal will give the energy giant access to Tilt’s 20 wind farms. Reuters has the story.

In Canada  

Air Canada has unveiled plans to fight climate change. Specifically, the airlines giant has committed to reducing greenhouse gases (GHG) by 20 per cent from flights by 2030, investing $50 million in sustainable aviation fuel (SAF), and ensuring net-zero emissions by 2050.

In other news, B.C. is facing mounting pressure to abstain from logging “old growth forests” while the government transitions to more sustainable forestry policies. A report titled A New Future for Old Forests called on the provincial government to act within six months to protect such forests in April 2020.

The province's Site C mega dam is billions over budget but will go ahead, the premier said, highlighting the energy sector's complexity.

Last September, the province announced, “it would temporarily defer old growth harvesting in close to 353,000 hectares in nine different areas.” The B.C. government will hold consultations with First Nations and other forestry stakeholders “to determine the next areas where harvesting may be deferred,” according to Forests Minister Katrine Conroy. The Canadian Press has more.

Separately, LNG powered with electricity could be a boon for B.C.'s independent power producers, analysts say.

Finally, Pickering Developments Inc. has come forward saying it will not “alter or remove the wetland” that was meant to house an Amazon facility, according to CBC News.

The announcement comes after CBC News’s previously reported that the Toronto and Region Conservation Authority (TRCA) was pressured to issue a construction permit to Pickering Developments Inc. by Doug Ford’s provincial government. However, on March 12, an official with Amazon Canada told CBC News that the company no longer wished to build a warehouse on the site.

“In light of a recent announcement that a new fulfilment centre will no longer be located on this property, this voluntary undertaking ensures that no work, legally authorized by that permit, will occur,” Pickering Development Inc. said in a statement provided to CBC Toronto.
