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.

Biden seen better for Canada’s energy sector

Biden Impact on Canadian Energy Exports highlights shifts in trade policy, tariffs, carbon pricing, and Keystone XL, with implications for aluminum, softwood lumber, electricity trade, fracking limits, and small modular nuclear reactors.

 

Key Points

How Biden-era trade, climate rules, and tariffs may reshape Canadian energy and exports.

✅ Reduced tariff volatility and friendlier trade policy toward allies

✅ Climate alignment: carbon pricing, clean power, cross-border electricity

✅ Potential gains for oil, gas, aluminum, and softwood lumber exporters

 

There is little doubt among industry associations, the Conference Board of Canada and C.D. Howe Institute that a Joe Biden White House will be better for Canadian resource and energy exporters – even Alberta’s beleaguered oil industry, despite Biden’s promise to kill the Keystone XL pipeline.

The consensus among industry observers in the lead-up to the November 3 U.S. presidential election was that a re-elected Donald Trump would become even more pugnacious on trade and protectionism, putting electricity exports at risk for Canadian utilities, which would be bad for Canadian exporters. The Justin Trudeau government would likely come under increased pressure to lower Canadian business taxes to compete with Trump’s low-tax climate.

“A Joe Biden victory would likely lead to higher taxes for both corporations and wealthy Americans to help pay down the gigantic fiscal deficit that is currently running at plus-US$5 trillion,” the conference board concluded in a recent analysis.

On trade and tariffs, the conference board said: “Many but not all of these ongoing trade disputes would wither away under a Joe Biden administration. He would likely run a broad trade policy favouring strategic allies like Canada.

While Canadian industries like forestry and aluminum smelting benefited from strong demand and prices in the U.S. under Trump, the forced renegotiation of the North American Free Trade Agreement failed end tariffs and duties on things like softwood lumber and aluminum ingots, even as Canadians backed tariffs on energy and minerals during the dispute.

The uncertainty over trade issues, and Trump’s tax cuts, which made Canada’s tax regime less competitive, have contributed to a period of low business investment in Canada during Trump's presidency.

“For Canada, we’ve seen a period, since this administration has been in power, where investment has eroded steadily,” conference board chief economist Pedro Antunes said. “We are not doing well at all, in terms of private capital investment in Canada.”

Alberta’s oil industry has been hit particularly hard, with a slew of divestments by big energy giants, and cancellations of major projects, like the $20 billion Frontier oilsands project, scrubbed by Teck Resources.

While domestic policies and global market forces are partly to blame for falling investments in Canada’s oil and gas sector, up until the pandemic hit, investment in oil and gas increased significantly in the U.S., while declining in Canada, during Trump’s first term.

Biden is also expected to level the playing field with respect to climate change policies. Canadian industries pay carbon taxes and face regulations that their counterparts in the U.S. don’t. That has disadvantaged energy-intensive, trade-exposed industries like mines and pulp mills in Canada.

“With Biden in office, Canada will once again have a partner at the federal level in the states in the transition to a decarbonized economy,” said Josha MacNab, national policy director for the Pembina Institute.

Biden’s policies might also favour importing aluminum, cross-laminated timber, fuel cells and other lower-carbon products and commodities from Canada.

At least one observer believes that Canada’s oil and gas sector might benefit more from a Biden White House, despite Biden’s pledge to kill the Keystone XL pipeline.

“I think Joe Biden could be very good for Alberta,” Christopher Sands, director of the Wilson International Center’s Canada Institute, said in a recent discussion hosted by the C.D. Howe Institute.

Sands added that the presidential permit Biden has promised to tear up on the Keystone XL pipeline project is a construction permit, not an operating permit.

“The segment of that pipeline that crosses the U.S.-Canada border, which is the only place that the presidential permit applies, has been built,” Sands said. “So I think that’s somewhat of an empty threat.”

He added that, if Biden bans fracking on federal lands, as he has promised, and implements other restrictions that make it more costly for American oil and gas producers, it might increase the demand for Canadian oil and gas in the U.S. The demand would be highest in the U.S. Midwest, which depends largely on Marcellus Shale production, notably in Pennsylvania, and Western Canada for its oil and gas.

One of the Canadian industries directly affected by the Trump administration was aluminum smelting, which is relevant for B.C. because Rio Tinto plc’s Kitimat smelter exports aluminum to the U.S.

Jean Simard, president of the Aluminum Association of Canada, said one of Trump’s legacies was the reactivation of a little-used mechanism – Section 232 of the Trade Expansion Act – to hit Canada and other countries, notably China, with import tariffs.

The 10 per cent tariffs on aluminum cost Canadian aluminum producers US$15 million in the month of August alone, Simard said.

The Trump administration eventually exempted Canadian aluminum exports from the tariffs, then reintroduced them, and then, one week before the election, exempted them again.

These on-again, off-again tariff threats create tremendous uncertainty, not just for Canadian producers, but also for U.S. buyers. That kind of uncertainty is likely to ease under a Biden presidency.

Simard said Biden’s track record suggests he is well-disposed towards Canada and less confrontational with allies and trade partners in general, and some in Washington have called for a stronger U.S.-Canada energy partnership as well.

Meanwhile, softwood lumber tariffs have been imposed by Democrats and Republicans alike. But there are compelling reasons for ending the Canada-U.S. softwood lumber war.

Home renovation and repair in the United States has done surprisingly well during the pandemic.

As a result of sawmill curtailments in the U.S. due to pandemic restrictions and high demand for lumber in the U.S. housing sector, North American lumbers prices broke records this summer, soaring as high as US$900 per thousand board feet.

“It shows that there’s very strong demand for our product,” said Susan Yurkovich, president of the Council of Forest Industries.

Ultimately, the duties Canadian lumber exporters pay are passed on to U.S. consumers.

Sands said Biden’s climate action pledges, including a clean electricity standard, could increase opportunities for trading electricity between Canada in the U.S., as the U.S. increasingly looks to Canada for green power, and could also be good for Canadian nuclear power technology.

Strong climate change policies necessarily result in an increased demand for low-carbon electricity, and advancing clean grids, which Canada has in abundance, thanks to both hydro and nuclear power.

“[Biden] does share the desire to act on climate change, but unlike some of his fellow party members who are more signed on to a Green New Deal, he’s open to pragmatic solutions that might get the job done quickly and efficiently,” Sands said.

“This is a huge opportunity for small, modular nuclear reactors, and Atomic Energy Canada has some great designs. There’s a real opportunity for a nuclear revival.”

Ukraine's Green Fightback: Rising from the Ashes with Renewable Energy

Ukraine Green Fightback advances renewable energy, energy independence, and EU integration, rebuilding war-damaged grids with solar, wind, and storage, exporting power to Europe, and scaling community microgrids for resilient, low-carbon recovery and REPowerEU alignment.

 

Key Points

Ukraine Green Fightback shifts to renewables and resilient grids, aiming 50% clean power by 2035 despite wartime damage.

✅ 50% renewable electricity target by 2035, up from 15% in 2021

✅ Community solar and microgrids secure hospitals and schools

✅ Wind and solar rebuild capacity; surplus exports to EU grids

 

Two years after severing ties with Russia's power grid, Ukraine stands defiant, rebuilding its energy infrastructure with a resolute focus on renewables. Amidst the ongoing war's devastation, a remarkable green fightback is taking shape, driven by a vision of a self-sufficient, climate-conscious future.

Energy Independence, Forged in Conflict:

Ukraine's decision to unplug from Russia's grid in 2022 was both a strategic move and a forced necessity, aligning with a wider pushback from Russian oil and gas across the continent. While it solidified energy independence aspirations, the full-scale invasion pushed the country into "island mode," highlighting vulnerabilities of centralized infrastructure.

Today, Ukraine remains deeply intertwined with Europe, inching towards EU accession and receiving global support, as Europe's green surge in clean energy gathers pace. This aligns perfectly with the country's commitment to environmental responsibility, further bolstered by the EU's own "REPowerEU" plan to ditch fossil fuels.

Rebuilding with Renewables:

The war's impact on energy infrastructure has been significant, with nearly half damaged or destroyed. Large-scale renewables have borne the brunt, with 30% of solar and 90% of wind farms facing disruption.

Yet, the spirit of resilience prevails. Surplus electricity generated by solar plants is exported to Poland, showcasing the potential of renewable sources and mirroring Germany's solar power boost across the region. Ambitious projects are underway, like the Tyligulska wind farm, Ukraine's first built in a conflict zone, already supplying clean energy to thousands.

The government's vision is bold: 50% renewable energy share by 2035, a significant leap from 2021's 15%, and informed by the fact that over 30% of global electricity already comes from renewables. This ambition is echoed by civil society groups who urge even higher targets, with calls for 100% renewable energy worldwide continuing to grow.

Community-Driven Green Initiatives:

Beyond large-scale projects, community-driven efforts are flourishing. Villages like Horenka and Irpin, scarred by the war, are rebuilding hospitals and schools with solar panels, ensuring energy security and educational continuity.

These "bright examples," as Svitlana Romanko, founder of Razom We Stand, calls them, pave the way for a broader green wave. Research suggests replacing all coal plants with renewables would cost a manageable $17 billion, paving the way for a future free from dependence on fossil fuels, with calls for a fossil fuel lockdown gaining traction.

Environmental Cost of War:

The war's ecological footprint is immense, with damages exceeding €56.7 billion. The Ministry of Environmental Protection and Natural Resources is meticulously documenting this damage, not just for accountability but for post-war restoration.

Their efforts extend beyond documentation. Ukraine's "EcoZagroza" app allows citizens to report environmental damage and monitor pollution levels, fostering a collaborative approach to environmental protection.

Striving for a Greener Future:

President Zelenskyy's peace plan highlights ecocide prevention and environmental restoration. The ministry itself is undergoing a digitalization push, tackling corruption and implementing EU-aligned reforms.

While the European Commission's recent progress report acknowledges Ukraine's strides, set against a Europe where renewable power has surpassed fossil fuels for the first time, the "crazy rhythm" of change, as Ecoaction's Anna Ackermann describes it, reflects the urgency of the situation. Finding the right balance between war efforts and green initiatives remains a crucial challenge.

Conclusion:

Ukraine's green fightback is a testament to its unwavering spirit. Amidst the darkness of war, hope shines through in the form of renewable energy projects and community-driven initiatives. By embracing a green future, Ukraine not only rebuilds but sets an example for the world, demonstrating that even in the face of adversity, sustainability can prevail.

This Thin-Film Turns Heat Waste From Electronics Into Electricity

Pyroelectric Energy Harvesting captures low-grade heat via thin-film materials, converting temperature fluctuations into power for waste heat recovery in electronics, vehicles, and industrial machinery, offering a thermoelectric alternative for microelectronics and exascale systems.

 

Key Points

Thin-film pyroelectric harvesting turns temperature changes into electricity, enabling low-grade waste heat recovery.

✅ Converts low-grade heat fluctuations into usable power

✅ Thin-film design suits microelectronics and edge devices

✅ Alternative to thermoelectrics for waste heat recovery

 

The electronic device you are reading this on is currently producing a modest to significant amount of waste heat that emerging thermoelectric materials could help recover in principle. In fact, nearly 70% of the energy produced annually in the US is ultimately wasted as heat, much of it less than 100 degrees Celsius. The main culprits are computers and other electronic devices, vehicles, as well as industrial machinery. Heat waste is also a big problem for supercomputers, because as more circuitry is condensed into smaller and smaller areas, the hotter those microcircuits get.

It’s also been estimated that a single next-generation exascale supercomputer could feasibly use up to 10% of the energy output of just one coal-fired power station, and that nearly all of that energy would ultimately be wasted as heat.

What if it were possible to convert that heat energy into a useable energy source, and even to generate electricity at night from temperature differences as well?

#google#

It’s not a new idea, of course. In fact the possibility of thermoelectric energy generation, where thermal energy is turned into electricity was recognised as early as 1821, around the same time that Michael Faraday developed the electric motor.

Unfortunately, when the heat source is ‘low grade’, aka less than 100 degrees Celsius, a number of limitations arise, and related approaches for nighttime renewable generation face similar challenges as well. For it to work well, you need materials that have quite high electrical conductivity, but low thermal conductivity. It’s not an easy combination to come by.

Taking a different approach, researchers at the University of California, Berkeley, have developed thin-film that uses pyroelectric harvesting to capture heat-waste and convert heat to electricity in prototype demonstrations. The findings were published today in Nature Materials.

Climate change, not renewables, threaten grid

New Mexico Energy Transition Act advances renewable energy, battery storage, energy efficiency, and demand response to boost grid reliability during climate change-fueled heatwaves, reducing emissions while supporting solar and wind deployment.

 

Key Points

A state policy phasing out power emissions, scaling renewables and storage, bolstering grid reliability in extreme heat.

✅ Replaces coal generation with solar plus battery storage

✅ Enhances grid reliability during climate-driven heatwaves

✅ Promotes energy efficiency and demand response programs

 

While temperatures hit record highs across much of the West in recent weeks and California was forced to curb electricity service amid heat-driven grid strain that week, the power stayed on in New Mexico thanks to proactive energy efficiency and conservation measures.

Public Service Company of New Mexico on Aug. 19 did ask customers to cut back on power use during the peak demand time until 9 p.m., to offset energy supply issues due to the record-breaking heatwave that was one of the most severe to hit the West since 2006. But the Albuquerque Journal's Aug. 28 editorial, "PRC should see the light with record heat and blackouts," confuses the problem with the solution. Record temperatures fueled by climate change – not renewable energy – were to blame for the power challenges last month. And thanks to the Energy Transition Act, New Mexico is reducing climate change-causing pollution and better positioned to prevent the worst impacts of global warming.

During those August days, more than 80 million U.S. residents were under excessive heat warnings. As the Journal's editorial pointed out, California experienced blackouts on Aug. 14 and 15 as wildfires swept across the state and temperatures rose. In fact, a recent report by the University of Chicago's Climate Impact Lab found the world has experienced record heat this summer due to climate change, and heat-related deaths will continue to rise in the future.

As the recent California energy incidents show, climate change is a threat to a reliable electricity system and our health as soaring temperatures and heatwaves strain our grid, as seen in Texas grid challenges this year as well. Demand for electricity rises as people depend more on energy-intensive air conditioning. High temperatures also can decrease transmission line efficiency and cause power plant operators to scale back or even temporarily stop electricity generation.

Lobbyists for the fossil fuel industry may claim that the service interruptions and the conservation requests in New Mexico demonstrate the need for keeping fossil-fueled power generation for electricity reliability, echoing policy blame narratives in California that fault climate policies. But fossil fuel combustion still is subject to the factors that cause blackouts – while also driving climate change and making resulting heatwaves more common. After an investigation, California's own energy agencies found no substance to the claim that renewable energy use was a factor in the situation there, and it's not to blame in New Mexico, either.

New Mexico's Energy Transition Act is a bold, necessary step to limit the damage caused by climate change in the future. It creates a reasonable, cost-saving path to eliminating greenhouse gas emissions associated with generating electricity.

The New Mexico Public Regulation Commission properly applied this law when it recently voted unanimously to replace PNM's coal-fired generation at San Juan Generating Station with carbon-free solar energy and battery storage located in the Four Corners communities, a prudent step given California's looming electricity shortage warnings across the West. The development will create jobs and provide resources for the local school district and help ensure a stronger economy and a healthier future for the region.

As we expand solar and wind energy here in New Mexico, we can help ensure reliable electricity service by building out greater battery storage for renewable energy resources. Expanding regional energy markets that can dispatch the lowest-cost energy from across the region to places where it is needed most would make renewable energy more available and reduce costs, despite concerns over policy exports raised by some observers.

Energy efficiency and demand response are important when we are facing extraordinary conditions, and proven strategies to improve electricity reliability show how demand-side tools complement the grid, so it is unfortunate that the Albuquerque Journal made the unsubstantiated claim that a stray cloud will put out the lights. It was hot, supplies were tight on the electric grid, and in those moments, we should conserve. We should not use those moments to turn our back on progress.

California allows electric school buses only from 2035

California Electric School Bus Mandate 2035 sets zero-emission requirements, outlines funding, state reimbursement, fleet electrification, infrastructure, and cost estimates, highlighting exemptions for frontier districts and alignment with clean transportation and climate policy goals.

 

Key Points

California's 2035 policy requires all new school buses be zero-emission, with funding and limited rural exemptions.

✅ Mandates zero-emission purchases for new school buses from 2035

✅ Estimates $5B transition cost with state reimbursement support

✅ Frontier districts may apply for 5-year extensions

 

California Governor Gavin Newsom has signed a new legislation requiring that from 2035, all newly ordered or contracted school buses must be zero-emission, a move aligned with California's push for expanded EV grid capacity statewide.

The state estimates that switching to electric school buses will cost around five billion dollars over the next decade, a projection reflecting electric bus challenges seen globally. That is because a diesel equivalent costs about 200,000 dollars less than a battery-electric version, as highlighted by critical analyses of California policy. And “the California Constitution requires the state to reimburse local agencies and school districts for certain costs mandated by the state.”

There are about 23,800 school buses on the road in California. About 500 are already electric, with conversion initiatives expected to expand the total, and 2,078 electric buses have been ordered.

There are – as always- exceptions to the rule. So-called “frontier districts,” which have less than 600 students or are in a county with a population density of less than ten persons per square mile, can file for a five-year extension, drawing on lessons from large electric bus fleets about route length and charging constraints. However, they must “reasonably demonstrate that a daily planned bus route for transporting pupils to and from school cannot be serviced through available zero-emission technology in 2035.”

Califonia is the fifth US state to mandate electric school buses, and jurisdictions like British Columbia are deploying electric school buses as well. Connecticut, Maryland, Maine, and New York implemented similar legislation, while California continues broader zero-emission freight adoption with Volvo VNR electric trucks entering service across the state.

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.”
