EV Tipping Point signals the S-curve shift to mainstream adoption as new car sales pass 5%, with the US joining Europe and China; charging infrastructure, costs, and supply align to accelerate electric car market penetration.

 

Key Points

The EV tipping point is when fully electric cars reach about 5% of new sales, triggering rapid S-curve adoption.

✅ 5% of new car sales marks start of mass adoption

✅ Follows S-curve seen in phones, LEDs, internet

✅ Barriers ease: charging, cost declines, model availability

 

Many people of a certain age can recall the first time they held a smartphone. The devices were weird and expensive and novel enough to draw a crowd at parties. Then, less than a decade later, it became unusual not to own one.

That same society-altering shift is happening now with electric vehicles, according to a Bloomberg analysis of adoption rates around the world. The US is the latest country to pass what’s become a critical EV tipping point: an EV inflection point when 5% of new car sales are powered only by electricity. This threshold signals the start of mass EV adoption, the period when technological preferences rapidly flip, according to the analysis.

For the past six months, the US joined Europe and China — collectively the three largest car markets — in moving beyond the 5% tipping point, as recent U.S. EV sales indicate. If the US follows the trend established by 18 countries that came before it, a quarter of new car sales could be electric by the end of 2025. That would be a year or two ahead of most major forecasts.

How Fast Is the Switch to Electric Cars?
19 countries have reached the 5% tipping point, and an earlier-than-expected shift is underway—then everything changes

Why is 5% so important? 
Most successful new technologies — electricity, televisions, mobile phones, the internet, even LED lightbulbs — follow an S-shaped adoption curve, with EVs going from zero to 2 million in five years according to market data. Sales move at a crawl in the early-adopter phase, then surprisingly quickly once things go mainstream. (The top of the S curve represents the last holdouts who refuse to give up their old flip phones.)

Electric cars inline tout
In the case of electric vehicles, 5% seems to be the point when early adopters are overtaken by mainstream demand. Before then, sales tend to be slow and unpredictable, and still behind gas cars in most markets. Afterward, rapidly accelerating demand ensues.

It makes sense that countries around the world would follow similar patterns of EV adoption. Most impediments are universal: there aren’t enough public chargers, grid capacity concerns linger, the cars are expensive and in limited supply, buyers don’t know much about them. Once the road has been paved for the first 5%, the masses soon follow.

Thus the adoption curve followed by South Korea starting in 2021 ends up looking a lot like the one taken by China in 2018, which is similar to Norway after its first 5% quarter in 2013. The next major car markets approaching the tipping point this year include Canada, Australia, and Spain, suggesting that within a decade many drivers could be in EVs worldwide.

"World?s Most Powerful? Tidal Turbine Starts Pumping Green Electricity To Onshore Grid

O2 Tidal Turbine delivers tidal energy in Orkney, Scotland, supplying grid-connected renewable power via EMEC and enabling green hydrogen production, providing clean electricity with predictable generation from strong coastal currents.

 

Key Points

A 2 MW, grid-connected tidal device in Orkney that delivers clean power and enables EMEC green hydrogen production.

✅ 2 MW capacity; powers ~2,000 UK homes via EMEC grid

✅ Predictable renewable output from strong coastal currents

✅ Enables onshore electrolyzer to produce green hydrogen

 

“The world’s most powerful” tidal turbine has been hooked up to the onshore electricity grid in Orkney, a northerly archipelago in Scotland, and is ready to provide homes with clean, green electricity, even as a major UK offshore windfarm begins supplying power this week.

The tidal turbine, known as the O2, was developed by Scottish engineering firm Orbital Marine Power. On July 28, they announced O2 “commenced grid connected power generation” at the European Marine Energy Centre (EMEC) in Orkney, meaning it's all set up and providing energy to the local power grid, similar to another Scottish tidal project that recently powered nearly 4,000 homes.

The 74-meter-long (242-foot) turbine is said to be “the world’s most powerful” tidal turbine. It will lay in the waters off Orkney for the next 15 years with the capacity to meet the annual electricity demand of around 2,000 UK homes. The 2MW turbine is also set to power the EMEC’s land-based electrolyzer that will generate green hydrogen (hydrogen made without fossil fuels) that can also be used as a clean energy source, in a UK energy system that recently set a wind generation record for output.

“Our vision is that this project is the trigger to the harnessing of tidal stream resources around the world and, alongside investment in UK offshore wind, to play a role in tackling climate change whilst creating a new, low-carbon industrial sector,” Orbital CEO, Andrew Scott, said in a press release.

Tidal energy is harnessed by converting energy from the natural rise and fall of ocean tides and currents. The O2 turbine consists of two submerged blades with a 20-meter (65-foot) diameter attached to a turbine that will move with the shifting currents of Orkney’s coast to generate electricity. Electricity is then transferred from the turbine along the seabed via cables towards the local onshore electricity network, a setup also being used by a Nova Scotia tidal project to supply the grid today.


This method of harnessing energy is not just desirable because it doesn't release carbon emissions, but it’s more predictable than other renewable energy sources, such as solar or Scotland's wind farms that can be influenced by weather conditions. Tidal energy production is still in its infancy and there are relatively few large-scale tidal power plants in the world, but many argue that some parts of the world could potentially draw huge benefits from this innovative form of hydropower, especially coastal regions with strong currents such as the northern stretches of the UK and the Bay of Fundy in Atlantic Canada.

The largest tidal power operation in the world is the Sihwa Lake project on the west coast of South Korea, which harnesses enough power to support the domestic needs of a city with a population of 500,000 people. However, once fully operational, the MeyGen tidal power project in northern Scotland hopes to snatch its title.

Electric car charging networks jostle for pole position amid Biden's push to electrify

EV Charging Infrastructure Expansion accelerates as DC fast charging, Level 2 stations, and 150-350 kW networks grow nationwide, driven by Biden's plan, ChargePoint, EVgo, and Electrify America partnerships at retailers like Walmart and 7-Eleven.

 

Key Points

The nationwide build-out of public EV chargers, focusing on DC fast charging, kW capacity, and retailer partnerships.

✅ DC fast chargers at 150-350 kW cut charge times

✅ Retailers add ports: Walmart and 7-Eleven expand access

✅ Investments surge via ChargePoint, EVgo, Electrify America

 

Today’s battery-electric vehicles deliver longer range at a lower cost, are faster and more feature-laden than earlier models. But there’s one particular challenge that still must be addressed: charging infrastructure across the U.S.

That’s a concern that President Joe Biden wants to address, with $174 billion of his proposed infrastructure bill to be used to promote the EV boom while expanding access. About 10 percent of that would help fund a nationwide network of 500,000 chargers.

However, even before a formal bill is delivered to Congress, the pace at which public charging stations are switching on is rapidly accelerating.

From Walmart to 7-Eleven, electric car owners can expect to find more and more charging stations available, as automakers strike deals with regulators, charger companies and other businesses, even as control of charging remains contested.

7-Eleven convenience chain already operates 22 charging stations and plans to grow that to 500 by the end of 2022. Walmart now lets customers charge up at 365 stores around the country and plans to more than double that over the next several years.

According to the Department of Energy, there were 20,178 public chargers available at the end of 2017. That surged to 41,400 during the first quarter of this year, as electric utilities pursue aggressive charging plans.

The vast majority of those available three years ago were “Level 2,” 240-volt AC chargers that would take as much as 12 hours to fully recharge today’s long-range BEVs, like the Tesla Model 3 or Ford Mustang Mach-E. Increasingly, new chargers are operating at 400 volts and even 800 volts, delivering anywhere from 50 to 350 kilowatts. The new Kia EV6 will be able to reach 80 percent of its full capacity in just 18 minutes.

“Going forward, unless there is a limit to the power we can access at a particular location, all our new chargers will have 150 to 350 kilowatt capacity,” Pat Romano, CEO of ChargePoint, one of the world’s largest providers of chargers, told NBC News.

ChargePoint saw its first-quarter revenues jump by 24 percent to $40.5 million this year, a surge largely driven by rapid growth in the EV market. Sales of battery cars were up 45 percent during the first quarter, compared to a year earlier. To take advantage of that growth, ChargePoint added another 6,000 active ports — the electric equivalent of a gas pump — during the quarter. It now has 112,000 active charge ports.

In March, ChargePoint became the world’s first publicly traded global EV charging network. It completed a SPAC-style merger with Switchback Energy Acquisition Corporation. Rival EVgo plans to go through a similar deal this month with the "blank check" company Climate Change Crisis Real Impact Acquisition Corporation (CRIS), which has valued the charge provider at $2.6 billion.

“We look forward to highlighting EVgo’s leadership position and its significant opportunity for long-term growth in the climate critical electrification of transport sector,” CRIS CEO David Crane said Tuesday, ahead of an investor meeting with EVgo.

Electrify America, another emerging giant, has its own deep-pocket backer. The suburban Washington, D.C.-based firm was created using $2 billion of the settlement Volkswagen agreed to pay to settle its diesel emissions scandal. It is doling that out in regular tranches and just announced $200 million in additional investments — much of that to set up new chargers.

Industry investments in BEVs will top $250 million this decade, and could even reach $500 billion. That's encouraging automakers like Volkswagen, Ford and General Motors to tie up with individual charger companies, including plans to build 30,000 chargers nationwide.

In 2019, GM set up a partnership with Bechtel to build a charger network that will stretch across the U.S.

Others are establishing networks of their own, as Tesla has done with its Supercharger network.

Each charging network is leveraging relationships to speed up installations. Ford is offering buyers of its Mustang Mach-E 250 kilowatt-hours of free energy through Electrify America stations and is also partnering with Bank of America to “let you charge where you bank,” the automaker said.

Even if Biden gets his infrastructure plan through Congress quickly, other government agencies are already getting in to the charger business, even as state power grids brace for increased loads. That includes New York State which, in May, announced plans to put 150 new ports into place by year-end.

"Expanding high-speed charging in local markets across the state is a crucial step in encouraging more drivers to choose EVs,” said Gov. Andrew Cuomo, adding that, "public-private partnerships enable New York to build a network of fast, affordable and reliable electric vehicle public charging stations in a nimble and affordable way."

One of the big questions is how many charging stations actually are needed. There are 168,000 gas stations in the U.S., according to the Dept. of Energy. But the goal is not a one-for-one match, stressed ChargePoint CEO Romano, because “80 percent of EV owners today charge at home, and energy storage promises added flexibility, … and we expect that to continue to be the case."

But there are still many potential owners who won’t be able to set up their own chargers, and a network will still be needed for those driving long distances. Until that happens, many motorists will be reluctant to switch.

Biden's Climate Bet Rests on Enacting a Clean Electricity Standard

Clean Electricity Standard drives Biden's infrastructure, grid decarbonization, and utility mandates, leveraging EPA regulation, renewables, nuclear, and carbon capture via reconciliation to reach 80% clean power by 2030 amid partisan Congress.

 

Key Points

A federal mandate to reach 80% clean U.S. power by 2030 using incentives and EPA rules to speed grid decarbonization.

✅ Targets 80% clean electricity by 2030 via Congress or reconciliation

✅ Mix of renewables, nuclear, gas with carbon capture allowed

✅ Backup levers: EPA rules, incentives, utility planning shifts

 

The true measure of President Biden’s climate ambition may be the clean electricity standard he tucked into his massive $2.2 trillion infrastructure spending plan.

Its goal is striking: 80% clean power in the United States by 2030.

The details, however, are vague. And so is Biden’s plan B if it fails—an uncertainty that’s worrisome to both activists and academics. The lack of a clear backup plan underscores the importance of passing a clean electricity standard, they say.

If the clean electricity standard doesn’t survive Congress, it will put pressure on the need to drive climate policy through targeted spending, said John Larsen, a power system analyst with the Rhodium Group, an economic consulting firm.

“I don’t think the game is lost at all if a clean electricity standard doesn’t get through in this round,” Larsen said. “But there’s a difference between not passing a clean electricity standard and passing the right spending package.”

In his few months in office, Biden has outlined plans to bring the United States back into the international Paris climate accord, pause oil and gas leasing on public lands, boost the electric vehicle market, and target clean energy investments in vulnerable communities, including plans to revitalize coal communities across the country, most affected by climate change.

But those are largely executive orders and spending proposals—even as early assessments show mixed results from climate law—and unlikely to last beyond his administration if the next president favors fossil fuel usage over climate policy. The clean electricity standard, which would decarbonize 80% of the electrical grid by 2030, is different.

It transforms Biden’s climate vision from a goal into a mandate. Passing it through Congress makes it that much harder for a future administration to undo. If Biden is in office for two terms, the United States would see a rate of decarbonization unparalleled in its history that would set a new bar for most of the world’s biggest economies.

But for now, the clean electricity standard faces an uncertain path through Congress and steep odds to getting enacted. That means there’s a good chance the administration will need a plan B, observers said.

Exactly what kind of climate spending can pass Congress is the very question the White House and congressional Democrats will be working on in the next few months, including upgrades to an aging power grid that affect renewables and EVs, as the infrastructure bill proceeds through Congress.

Negotiations are fraught already. Congress is almost evenly split between a party that wants to curtail the use of fossil fuels and another that wants to grow them, and even high energy prices have not necessarily triggered a green transition in the marketplace.

Senate Minority Leader Mitch McConnell (R-Ky.) said last week that “100% of my focus is on stopping this new administration.” He made similar comments at the start of the Obama administration and blocked climate policy from getting through Congress. He also said last week that no Republican senators would vote for Biden’s infrastructure spending plan.

A clean electricity standard has been referred to as the “backbone” of Biden’s climate policy—a way to ensure his policies to decarbonize the economy outlast a future president who would seek to roll back his climate work. Advocates say hitting that benchmark is an essential milestone in getting to a carbon-free grid by 2035. Much of President Obama’s climate policy, crafted largely through regulations and executive orders, proved vulnerable to President Trump’s rollbacks.

Biden appears to have learned from those lessons and wants to chart a new course to mitigate the worst effects of climate change. He’s using his majority in the House and Senate to lock in whatever he can before the 2022 midterms, when Democrats are expected to lose the House.

To pass a clean electricity standard, virtually every Democrat must be on board, and even then, the only chance of success is to pass a bill through the budget reconciliation process that can carry a clean electricity standard. Some Senate Democrats have recently hinted that they were willing to split the bill into pieces to get it through, while others are concerned that although this approach might win some GOP support on traditional infrastructure such as roads and bridges, it would isolate the climate provisions that make up more than half of the bill.

The most durable scenario for rapid electricity-sector decarbonization is to lock in a bipartisan clean electricity standard into legislation with 60 votes in the Senate, said Mike O’Boyle, the director of electricity policy for Energy Innovation. Because that’s highly unlikely—if not impossible—there are other paths that could get the United States to the 80% goal within the next decade.

“The next best approach is to either, or in combination, pursue EPA regulation of power plant pollution from existing and new power plants as well as to take a reconciliation-based approach to a clean electricity standard where you’re basically spending federal dollars to provide incentives to drive clean electricity deployment as opposed to a mandate per se,” he said.

Either way, O’Boyle said the introduction of the clean electricity standard sets a new bar for the federal government that likely would drive industry response even if it doesn’t get enacted. He compared it to the Clean Power Plan, Obama’s initiative to limit power plant emissions. Even though the plan never came to fruition, because of a Clean Power Plan rollback, it left a legacy that continues years later and wasn’t negated by a president who prioritized fossil fuels over the climate, he said.

“It never got enacted, but it still created a titanic shift in the way utilities plan their systems and proactively reposition themselves for future carbon regulation of their electricity systems,” O’Boyle said. “I think any action by the Biden administration or by Congress through reconciliation would have a similar catalytic function over the next couple years.”

Some don’t think a clean electricity standard has a doomed future. Right now, its provisions are vague. But they can be filled in in a way that doesn’t alienate Republicans or states more hesitant toward climate policy, said Sally Benson, an engineering professor at Stanford University and an expert on low-carbon energy systems. The United States is overdue for a federal mandate that lasts through multiple administrations. The only way to ensure that happens is to get Republican support.

She said that might be possible by making the clean electricity standard more flexible. Mandate the goals, she said, not how states get there. Going 100% renewable is not going to sell in some states or with some lawmakers, she added. For some regions, flexibility will mean keeping nuclear plants open. For others, it would mean using natural gas with carbon capture, Benson said.

While it might not meet the standards some progressives seek to end all fossil fuel usage, it would have a better chance of getting enacted and remaining in place through multiple presidents, she said. In fact, a clean electricity standard would provide a chance for carbon capture, which has been at the center of Republican climate policy proposals. Benson said carbon capture is not economical now, but the mandate of a standard could encourage investments that would drive the sector forward more rapidly.

“If it’s a plan that people see as shutting the door to nuclear or to natural gas plus carbon capture, I think we will face a lot of pushback,” she said. “Make it an inclusive plan with a specific goal of getting to zero emissions and there’s not one way to do it, meaning all renewables—I think that’s the thing that could garner a lot of industrial support to make progress.”

In addition to industry, Biden’s proposed clean electricity standard would drive states to do more, said Larsen of the Rhodium Group. Several states already have their own version of a clean energy standard and have driven much of the national progress on carbon emissions reduction in the last four years, he said. Biden has set a new benchmark that some states, including those with some of the biggest economies in the United States, would now likely exceed, he said.

“It is rare for the federal government to get out in front of leading states in clean energy policy,” he said. “This is not usually how climate policy diffusion works from the state level to the federal level; usually it’s states go ahead and the federal government adopts something that’s less ambitious.”

Bus depot bid to be UK's largest electric vehicle charging hub

First Glasgow Electric Buses will transform the Caledonia depot with 160 charging points, zero-emission operations, grid upgrades, and rapid charging, supported by Transport Scotland funding and Alexander Dennis manufacturing for cleaner urban routes by 2023.

 

Key Points

Electric single-deckers at Caledonia depot with 160 chargers and upgrades, delivering zero-emission service by 2023

✅ 160 charging points; 4-hour rapid recharge capability

✅ Grid upgrades to power a fleet equal to a 10,000-person town

✅ Supported by Transport Scotland; built by Alexander Dennis

 

First Bus will install 160 charging points and replace half its fleet with electric buses at its Caledonia depot in Glasgow.

The programme is expected to be completed in 2023, similar to Metro Vancouver's battery-electric rollout milestones, with the first 22 buses arriving by autumn.

Charging the full fleet will use the same electricity as it takes to power a town of 10,000 people.

The scale of the project means changes are needed to the power grid, a challenge highlighted in global e-bus adoption analysis, to accommodate the extra demand.

First Glasgow managing director Andrew Jarvis told BBC Scotland: "We've got to play our part in society in changing how we all live and work. A big part of that is emissions from vehicles.

"Transport is stubbornly high in terms of emissions and bus companies need to play their part, and are playing their part, in that zero emission journey."

First Bus currently operates 337 buses out of its largest depot with another four sites across Glasgow.

The new buses will be built by Alexander Dennis at its manufacturing sites in Falkirk and Scarborough.

The transition requires a £35.6m investment by First with electric buses costing almost double the £225,000 bill for a single decker running on diesel.

But the company says maintenance and running costs, as seen in St. Albert's electric fleet results, are then much lower.

The buses can run on urban routes for 16 hours, similar to Edmonton's first e-bus performance, and be rapidly recharged in just four hours.

This is a big investment which the company wouldn't be able to achieve on its own.

Government grants only cover 75% of the difference between the price of a diesel and an electric bus, similar to support for B.C. electric school buses programmes, so it's still a good bit more expensive for them.

But they know they have to do it as a social responsibility, and large-scale initiatives like US school bus conversions show the direction of travel, and because the requirements for using Low Emissions Zones are likely to become stricter.

The SNP manifesto committed to electrifying half of Scotland's 4,000 or so buses within two years.

Some are questioning whether that's even achievable in the timescale, though TTC's large e-bus fleet offers lessons, given the electricity grid changes that would be necessary for charging.

But it's a commitment that environmental groups will certainly hold them to.

Transport Scotland is providing £28.1m of funding to First Bus as part of the Scottish government's commitment to electrify half of Scotland's buses in the first two years of the parliamentary term.

Net Zero Secretary Michael Matheson said: "It's absolute critical that we decarbonise our transport system and what we have set out are very ambitious plans of how we go about doing that.

"We've set out a target to make sure that we decarbonise as many of the bus fleets across Scotland as possible, at least half of it over the course of the next couple of years, and we'll set out our plans later on this year of how we'll drive that forward."

Transport is the single biggest source of greenhouse gas emissions in Scotland which are responsible for accelerating climate change.

In 2018 the sector was responsible for 31% of the country's net emissions.

Electric bus
First Glasgow has been trialling two electric buses since January 2020.

Driver Sally Smillie said they had gone down well with passengers because they were much quieter than diesel buses.

She added: "In the beginning it was strange for them not hearing them coming but they adapt very easily and they check now.

"It's a lot more comfortable. You're not feeling a gear change and the braking's smoother. I think they're great buses to drive."

California looks to electric vehicles for grid stability

California EV V2G explores bi-directional charging, smart charging, and demand response to enhance grid reliability. CPUC, PG&E, and automakers test incentives aligning charging with solar and wind, helping prevent blackouts and curtailment.

 

Key Points

California EV V2G uses two-way charging and smart incentives to support grid reliability during peak demand.

✅ CPUC studies feasibility, timelines, and cost barriers to V2G

✅ Incentives shift charging to align with solar, wind, off-peak hours

✅ High-cost bidirectional chargers and warranties remain hurdles

 

California energy regulators are eyeing the power stored in electric vehicles as they hunt for ways to avoid blackouts caused by extreme weather.

While few EV and their charging ports are equipped to deliver electricity back into the grid during emergencies, the California Public Utilities Commission wants more data on it as the agency rules on steps utilities must take to ensure they have enough power for this summer and next year. A draft CPUC decision due to be discussed this week asks about the feasibility of reversing the charge when needed (Energywire, March 8).

“Very few [EVs], maybe a couple of thousand at the most, can give power to the grid, and even fewer are connected into a charger that can do it,” said Gil Tal, director of the Plug-in Hybrid & Electric Vehicle Research Center at the University of California, Davis. EVs that feature the ability “have it at a more experimental level.”

The issue arises as California, where about half of all U.S. EVs are purchased, examines what role the vehicles can play in keeping lights on and refrigerators running and how a much bigger grid will support them in the long term. Even if grid operators can’t pull from EV batteries en masse, experts say cash and other incentives can prompt drivers to shift charging times, boosting grid stability.

“What we can do is not charge the electric cars at times of high demand” such as during heat waves, Tal said.

The EV focus comes after California’s grid manager last summer imposed rolling blackouts when power supplies ran short during a record-shattering heat wave. State energy regulators across the U.S., as EVs challenge state grids, are also looking at their disaster preparedness as Texas recovers from a winter storm last month that cut off electricity for more than 4 million homes and businesses there.

California’s EV efforts can help other states as they add more renewable power to their grids, said Adam Langton, energy services manager at BMW of North America.

That automaker ran a pilot program with San Francisco-based utility Pacific Gas & Electric Co. (PG&E) looking at whether money and other incentives could prompt EV drivers to charge their cars at different times. The payments successfully shifted charging to the middle of the night, when wind power often is plentiful. It also moved some repowering to mornings and early afternoons, when there’s abundant solar energy.

“That can be a tool that the utilities can use to deal with supply issues,” Langton said. “What our research has shown is that vehicles can contribute to [conservation] needs and emergency supply by shifting their charging time.”

Such measures can also help states avoid having to curtail solar production on days when there’s more generation than needed. On many bright days, California has more solar power than it can use.

“As more states add more renewable energy, we think that they’re going to find that EVs complement that really well with smart charging, because grid coordination can get that charging to align with the renewable energy,” Langton said. “It allows to add more and more renewable energy.”

High-cost equipment a hurdle
The CPUC at a future workshop plans to collect information on leveraging EVs to head off power shortages at key times.

But Tal said it will probably take a decade to get enough EVs capable of exporting electricity back to utilities “in high numbers that can make an impact on the grid.”

Barriers to reaching such “vehicle to grid” integration are technical and economic, he said. EVs export direct current and need a device on the other side that can convert it to alternating current, similar to a solar power inverter for rooftop panels.

However, the equipment known as a V2G capable charger is costly. It ranges from $4,500 to $5,500, according to a 2017 National Renewable Energy Laboratory report.

PG&E and Los Angeles-based Southern California Edison already have “expressed doubt that short-term measures could be developed in time to expand EV participation by summer 2021” in V2G programs, the draft CPUC proposal said. The utilities suggested instead that the agency encourage EV owners to participate in initiatives where they’d get paid for reducing power consumption or sell electricity back to the grid when needed, known as demand response programs.

Still, almost all major EV automakers are looking at two-directional charging, Tal said.

“The incentive is you can get more value for the car,” he said. “The disincentive is you add more miles in a way on the car,” because an owner would be discharging to the grid and re-charging, and “the battery has limited life.”

And right now, discharging a vehicle to the grid would violate many warranties, he said. Car manufacturers would need to agree to change that and could call for compensation in return.

Meanwhile, San Diego Gas & Electric Co., a Sempra Energy subsidy, plans to launch a pilot looking at delivering power to the grid from electric school buses. The six buses in the pilot transport students in El Cajon, Calif., east of San Diego.

“The buses are perfect because of their big batteries and predictable schedule,” Jessica Packard, SDG&E spokesperson, said in an email. “Ultimately, we hope to scale up and deploy these kinds of innovations throughout our grid in the future.”

She declined to say how much power the buses could deliver because the project isn’t yet operating. It’s set to start later this year.

Mobility needs
While BMW and PG&E did not review vehicle-to-grid power transfers in their own 2017 research ending last year, one study in Delaware did. But it was in a university setting about eight years ago and didn’t look at actual drivers, said Langton with BMW.

In their own findings from the San Francisco Bay Area pilot program, BMW and PG&E found that incentives could quickly change driver behavior in terms of charging.

Technology helps: Most new EVs have timers that allow the driver to control when to charge and when to stop charging. Langton said the pilot program got drivers to have their cars charge from roughly 2 to 6 a.m., when electricity rates typically are lowest.

There can be a lot of solar energy during the day, but in summer, optimum charging times get more complicated in California, he said. People want to run their air conditioners during peak heat hours, so it’s important to be able to get EV drivers to shift to less congested times, he said.

With the right incentives or messaging, Langton said, the pilot persuaded drivers to move charging from 10 a.m. to 2 p.m. or noon to 4 p.m. BMW technology allowed for detailed information on battery charge level, ideal charging times and other EV data to be transmitted electronically after plugging in.

The findings are a good first step toward future vehicle-to-grid integration, Langton added.

“One of the things we really pay attention to when we do smart charging is, ‘How does the driver’s mobility needs figure into shifting their charging?'” he said. “We want to make sure that our customers can always do the driving that they need to do.”

The pilot included safeguards such as an opt-out button if the driver wanted to charge immediately. It also made sure the vehicle had a certain level of minimum charge — 15% to 20% — before the delayed smart charging kicked in.

Vehicle-to-grid technology would need to wrestle with the same concepts in a different way. If a car is getting discharged, the driver would want assurances its battery wouldn’t dip below a level that meets their mobility needs, Langton said.

“If that happened even once to a customer, they would probably not want to participate in these programs in the future,” he said.

One group adding charging stations across the country said it isn’t tweaking pricing based on when drivers charge. That’s to help grow EV purchases, said Robert Barrosa, senior director of sales and marketing at Volkswagen AG subsidiary Electrify America, which operates about 450 charging stations in 45 states.

The company has installed battery storage at more than 100 sites to make sure they can provide power at consistent prices even if California or another state calls for energy conservation.

“It’s very important for vehicle adoption that the customer have that,” Barrosa said.

The company could sell that battery storage back to the grid if there are shortfalls, but some market changes are needed first, particularly in California, he said. That’s because the company buys electricity on the retail side but would be sending it back into the wholesale market.

With that cost differential, Barrosa said, “it doesn’t make sense.”

Public Services and Procurement Canada (PSPC) is taking concrete steps to meet the Government of Canada's commitment in the Greening Government Strategy to reduce greenhouse gas emissions from federal government buildings, vehicle fleets and other operations, aligning with broader vehicle electrification trends across Canada.

The Honourable Anita Anand, Minister of Public Services and Procurement, announced the Government of Canada has launched Requests for Proposal to buy new clean electricity in the province of Alberta, which is moving ahead with the retirement of coal power to clean its grid, to power federal operations there.

As well, Canada will purchase Renewable Energy Certificates (REC) from new clean energy generation in Canada. This will enable Canada to attribute its energy consumption as clean in regions where new clean renewable sources are not yet available. The Government of Canada is excited about this opportunity to stimulate net new Canadian clean electricity generation through the procurement of RECs and complementary power purchase agreements that secure long-term supply for federal demand.

Together, these contracts will help to ensure Canada is reducing its greenhouse gas footprint by approximately 133 kilotonnes or 56% of total real property emissions in Alberta. Additionally, the contracts will displace approximately 41 kilotonnes of greenhouse gas emissions from electricity use in the rest of Canada, supporting progress toward 2035 clean electricity goals even as challenges remain.

Through these open, fair and transparent competitive procurement processes, PSPC will be a key purchaser of clean electricity and will support the growth of new clean electricity and renewable power infrastructure, such as recent turbine investments in Manitoba that expand capacity.

The Government of Canada's Clean Electricity Initiative plans to use 100% clean electricity by 2022, where available, in alignment with evolving net-zero electricity regulations that shape supply choices, to reduce greenhouse gas emissions and stimulate growth in clean renewable power infrastructure. PSPC has applied the goals of the Government of Canada's Clean Electricity Initiative to its specific requirement for net new clean electricity generation to power federal operations in Alberta.  

These procurements will support economic opportunities for Indigenous businesses by encouraging participation in the move towards clean energy, seen in provincial shifts toward clean power in Ontario that broaden markets. Each Request for Proposal incorporates mandatory requirements for Indigenous participation through equity holdings or set-asides under the Procurement Strategy for Aboriginal Business.
