Vehicle-to-Grid (V2G) enables bidirectional charging, letting EV batteries supply smart grid services to large buildings, support renewable energy integration, reduce battery degradation, and optimize demand response for efficient, resilient power management.

 

Key Points

Vehicle-to-Grid (V2G) is bidirectional EV charging that feeds the grid and buildings while protecting battery health.

✅ Uses idle EVs to power buildings and support renewables

✅ Smart algorithms minimize lithium-ion battery degradation

✅ Provides grid services, demand response, and peak shaving

 

Stored energy from electric vehicles (EVs) can be used to power large buildings -- creating new possibilities for the future of smart, renewable energy -- thanks to ground-breaking battery research from WMG at the University of Warwick.

Dr Kotub Uddin, with colleagues from WMG's Energy and Electrical Systems group and Jaguar Land Rover, has demonstrated that vehicle-to-grid (V2G) technology can be intelligently utilised to take enough energy from idle EV batteries to be pumped into the grid and power buildings -- without damaging the batteries.

This new research into the potentials of V2G shows that it could actually improve vehicle battery life by around ten percent over a year.

For two years, Dr Uddin's team analysed some of the world's most advanced lithium ion batteries used in commercially available EVs -- and created one of the most accurate battery degradation models existing in the public domain -- to predict battery capacity and power fade over time, under various ageing acceleration factors -- including temperature, state of charge, current and depth of discharge.

Using this validated degradation model, Dr Uddin developed a 'smart grid' algorithm, which supports grid coordination and intelligently calculates how much energy a vehicle requires to carry out daily journeys, and -- crucially -- how much energy can be taken from its battery without negatively affecting it, or even improving its longevity.

The researchers used their 'smart grid' algorithm to see if they could power WMG's International Digital Laboratory -- a large, busy building which contains a 100-seater auditorium, two electrical laboratories, teaching laboratories, meeting rooms, and houses approximately 360 staff -- with vehicle-to-building charging from EVs parked on the University of Warwick campus.

They worked out that the number of EVs parked on the campus (around 2.1% of cars, in line with the UK market share of EVs) could spare the energy to power this building, acting as capacity on wheels for electricity networks -- and that in doing so, capacity fade in participant EV batteries would be reduced by up to 9.1%, and power fade by up to 12.1% over a year.

It has previously been thought that extracting energy from EVs with V2G technology causes their lithium ion batteries to degrade more rapidly.

Dr Uddin's group (along with collaborators from Jaguar Land Rover) have proved, however, that battery degradation is more complex -- and this complexity, in operation, can be exploited to improve a battery's lifetime.

Given that battery degradation is dependent on calendar age, capacity throughput, temperature, state of charge, current and depth of discharge, V2G is an effective tool that can be used to optimise a battery's conditions such that degradation is minimised. Hence, taking excess energy from an idle EV to power the grid actually keeps the battery healthier for longer.

Dr Uddin commented on the research:

"These findings reinforce the attractiveness of vehicle-to-grid technologies to automotive Original Equipment Manufacturers: not only is vehicle-to-grid an effective solution for grid support -- and subsequently a tidy revenue stream -- but we have shown that there is a real possibility of extending the lifetime of traction batteries in tandem.

"The results are also appealing to policy makers interested in grid decarbonisation and addressing grid challenges from rising EVs across power systems."

The research, 'On the possibility of extending the lifetime of lithium-ion batteries through optimal V2G facilitated by an integrated vehicle and smart-grid system' is published in Energy.

It was funded by the Engineering and Physical Sciences Research Council and the WMG centre High Value Manufacturing Catapult, in partnership with Jaguar Land Rover.

St. Albert touts green goals with three new electric buses

St. Albert electric buses debut as zero-emission, quiet public transit, featuring BYD technology, long-range batteries, and charging stations, serving Edmonton routes while advancing sustainable transportation goals and a future fleet expansion.

 

Key Points

They are zero-emission BYD transit buses that cut noise and air pollution, with long-range batteries and city charging.

✅ Up to 250-280 km range per charge

✅ Quiet, zero-emission operations reduce urban pollution

✅ Backed by provincial GreenTRIP funding and BYD tech

 

The city of St. Albert is going green — both literally and esthetically — with three electric buses on routes in and around the city this week.

"They're virtually silent," Wes Brodhead, chair of the Capital Region Board transit committee and a St. Albert city councillor, said. "This, as opposed to the diesel buses and the roar that accompanies them as they drive down the street."

You may not hear them coming but you'll definitely see them, as electric school buses in B.C. hit the road as well.

The 35-foot electric buses are painted bright green to represent the city's goal of adopting sustainable transportation.

"There's no noise pollution, there's no air pollution, and it just kind of fit with the whole theme of the city," said St. Albert Transit director Kevin Bamber.

'The conversation around the conference was not if but when the industry will fully embrace electrification,' - Wes Brodhead, St. Albert city councillor

The buses cost about $970,000 each. Adding in the required infrastructure, including charging stations, the project cost a total of $3.1 million, with two-thirds of the funding coming from the provincial government's Green Transit Incentives Program. 

The electric buses are estimated to go between 250 and 280 kilometres on a single charge.

"That would mean any of the routes that we currently have through St. Albert or into Edmonton, an electric bus could do the morning route, come back, park in the afternoon and go back out and do the afternoon route without a charge," Bamber said. 

St. Albert councillor Wes Brodhead envisions having a full fleet of 60 electric buses in years to come, a scale informed by examples like the TTC's electric bus fleet operating in North America. (Supplied)

Brodhead went to an international transit conference in Montreal, where STM electric buses have begun rolling out and he said manufacturers presented various electric bus designs. 

"The conversation around the conference was not if but when the industry will fully embrace electrification," Brodhead said.

The vehicles were built in California by BYD Ltd., one of only two companies making the long-endurance electric buses.

The city has ordered four more of the buses and hopes to be running all seven by the end of the year, as battery-electric buses in Metro Vancouver continue to hit the roads nationwide.

Eventually, Brodhead envisions having a full fleet of 60 electric buses in St. Albert.

Edmonton is expected to operate as many as 40 electric buses, and while city staff are still in the planning stages, Edmonton's first electric bus has already hit city streets.

UK must be ready for rise of electric vehicles, says ABB chief

UK EV Charging Infrastructure is accelerating as ABB and Formula E spotlight fast charging, smart grids, and public stations, preparing Britain for mass electric vehicle adoption with expanded capacity, reliable connectors, and nationwide coverage.

 

Key Points

The UK network of charge points, grid capacity, and services enabling secure, scalable electric vehicle adoption.

✅ ABB urges rapid rollout of fast chargers and smart grid upgrades

✅ National Grid forecasts up to 9m EVs by 2030 in the UK

✅ Government GBP 400m investment targets reliable nationwide coverage

 

The UK should speed up preparations for the rise of electric vehicles, according to the chief executive of ABB, the world’s largest supplier of fast-charging points.

Speaking as the Switzerland-based engineering firm became the first official sponsor of the electric street racing series Formula E, Ulrich Spiesshofer predicted a flood of consumer take-up of plug-in cars, noting how EV inquiries surged in the UK during a recent fuel supply crisis.

And he added his voice to warnings that Britain must move faster to make sure owners of electric vehicles are not stymied by a shortage of charging bays or cost concerns among consumers.

“E-mobility is unstoppable, it’s just a question of how fast and how deep it will be deployed,” he said. “The UK has a big population that really wants to contribute to a greener, more sustainable world. But there’s always a question of whether it’s quick enough. In the next couple of years, it’s in the interest of everybody to make sure the infrastructure is coming up.”

 

How green are electric cars?

He said this would include adding to the UK’s network of electric charging points, as well as ensuring enough energy capacity so that the grid can cope with rising demand.

There are 14,344 charging connectors in the UK, according to ZapMap, which charts the scale of the UK’s network.

Those charging points served around 132,000 plug-in vehicles at the end of 2017, but the National Grid has predicted that the number of electric cars could surge to 9m by 2030.

“In the next couple of years, it’s in the interest of everybody to make sure the infrastructure is coming up,” said Spiesshofer.

He welcomed the government’s budget pledge to spend £400m on improving the UK’s charging point network but warned that the power grid also needed to be ready to meet the increased demand, which many argue is manageable with proper management approaches.

Electric cars have been forecast to add about 18 gigawatts of power demand to the grid, the equivalent of six Hinkley Point C nuclear power stations.

Spiesshofer said he hoped ABB’s sponsorship of Formula E, which will last until 2025, would help spur interest in electric cars and lead to technological breakthroughs, even as the US EV boom tests charging capacity elsewhere.

Tesla’s lead battery expert hired by Uber to help power its ‘flying car’ service

Uber Elevate eVTOL Batteries enable electric air taxis with advanced energy storage, lithium-ion cell quality, safety engineering, and zero-emissions performance for urban air mobility, ride-hailing aviation, and scalable battery pack development.

 

Key Points

Battery systems for Uber's electric air taxis, maximizing energy density, safety, and cycle life for urban air mobility.

✅ Ex-Tesla battery leader guides pack design and cell quality

✅ All-electric eVTOL targets zero-emissions urban air mobility

✅ Focus on safety, energy density, fast charge, and lifecycle

 

Celina Mikolajczak, a senior manager for battery pack development at Tesla, has been hired by Uber to help the ride-hail company’s “flying car” project get off the ground. It’s an important hire because it signals that Uber plans to get more involved in the engineering aspects of this outlandish-sounding project.

For six years, Mikolajczak served as senior manager and technical lead for battery technology, cell quality, and materials analysis. She worked with Tesla’s suppliers, tested the car company’s lithium-ion batteries for long-term use as the age of electric cars accelerates, oversaw quality assurance, and conducted “failure analysis” to drive battery cell production and design improvements. In other words, Mikolajczak was in charge of making sure the most crucial component in Tesla’s entire assembly line was top of the line.

Now she works for Uber — and not just for Uber, but for Uber Elevate, the absurdly ambitious air taxi service that hinges on the successful development of electric vertical take-off and landing (eVTOL) vehicles. There are practically zero electric planes in service today, and definitely none being used in a commercial ride-hail service. The hurdles to getting this type of service off the ground are enormous.

Her title at Uber is director of engineering and energy storage systems, and today marks her first week on the job. She joins Mark Moore, the former chief technologist for on-demand mobility at NASA’s Langley Research Center, who joined Uber almost a year ago to help lend a professional appearance to Elevate. Both serve under Jeff Holden, Uber’s head of product, who oversees the air taxi project.

Uber first introduced its plan to bring ride-sharing to the skies in a white paper last year. At the time, Uber said it wasn’t going to build its own eVTOL aircraft, but stood ready to “contribute to the nascent but growing VTOL ecosystem and to start to play whatever role is most helpful to accelerate this industry’s development.”

Instead, Uber said it would be partnering with a handful of aircraft manufacturers, real estate firms, and government regulators to better its chances of developing a fully functional, on-demand flying taxi service. It held a day-long conference on the project in Dallas in April, and plans to convene another one later this year in Los Angeles. In 2020, Uber says its aerial service will take off in three cities: LA, Dallas-Fort Worth, and Dubai.

 

UBER’S TAKING A MORE PROMINENT ROLE

Now, Uber’s taking a more prominent role in the design and manufacturing of its fleet of air taxis, which signals a stronger commitment to making this a reality — and also more of a responsibility if things eventually go south, as setbacks like Eviation's collapse underscore.

Perhaps most ambitiously, Uber says the aircraft it plans to use (but, importantly, do not exist yet) will run on pure battery-electric power, and not any hybrid of gasoline and electricity. Most of the companies exploring eVTOL admit that battery’s today aren’t light enough or powerful enough to sustain flights longer than just a few minutes, but many believe that battery technology will eventually catch up, with Elon Musk suggesting a three-year timeline for cheaper, more powerful cells.

Uber believes that in order to sustain a massive-scale new form of transportation, it will need to commit to an all-electric, zero-operational emissions approach from the start, even as potential constraints threaten the EV boom overall. And since the technology isn’t where it needs to be yet, the ride-hail company is taking a more prominent role in the development of the battery pack for its air taxi vehicles. Mikolajczak certainly has her work cut out for her.

New Alberta bill enables consumer price cap on power bills

Alberta Electricity Rate Cap shields RRO customers with a 6.8 cents/kWh price ceiling, stabilizing power bills amid capacity market transition, using carbon tax funding to offset spikes and enhance consumer protection from volatility.

 

Key Points

A four-year 6.8 cents/kWh ceiling on Alberta's RRO power price, backed by carbon tax to stabilize bills.

✅ Applies to RRO customers from Jun 2017 to May 2021

✅ Caps rates at 6.8 cents/kWh; lower RRO still applies

✅ Funded by carbon tax when market prices exceed cap

 

The Alberta government introduced a bill Tuesday, part of new electricity rules that will allow it to place a cap on regulated electricity rates for the next four years.

The move to cap consumer power rates at a maximum of 6.8 cents per kilowatt-hour for four years was announced in November 2016 by Premier Rachel Notley, although it was later scrapped by the UCP during a subsequent policy shift.

The cap is intended to protect consumers from price fluctuations from June 1, 2017, to May 31, 2021, as the province moves from a deregulated to a capacity power market amid a power market overhaul that is underway.

The price ceiling will apply to people with a regulated rate option. If the RRO is below 6.8 cents, they will still pay the lower rate.

The government isn't forecasting price fluctuations above 6.8 cents in this four-year period. If the price goes above that amount, funding would come from the carbon tax if required.

Funding may come from carbon tax

"We're taking a number of steps to keep prices low," said Energy Minister Marg McCuaig-Boyd. "But in the event that prices were to spike, the cap would automatically prevent the energy rate from going over 6.8 cents to give Albertans even more peace of mind." 

The government isn't forecasting price fluctuations above 6.8 cents in this four-year period. If the price goes above that amount, funding would come from the carbon tax.

McCuaig-Boyd said this would be an appropriate use for the carbon tax as the cap helps Albertans move to a greener energy system and change how the province produces and pays for electricity without relying as much on coal-fired electricity. 

The government estimates the program will cost $10 million a month for each cent the rate goes above 6.8 cents per kilowatt-hour. If rates remain below that amount, the program may not cost anything.

Wildrose electricity and renewables critic Don MacInytre said the move shows the government expects retail electricity rates will double over the next four years. 

MacIntyre argued a rate cap simply shifts increasing electricity costs away from consumers to the Alberta government. But ultimately everyone pays. 

"It's simply a shift of a burden from the ratepayer to the taxpayer, which is essentially the same person," he said. 

The City of Medicine Hat runs its own electrical system without a regulated rate option. The government will talk with the city to see if it is interested in taking part in the price cap protection.

About 60 per cent of eligible Albertans or one million households use the regulated rate option in their electricity contracts.

The current regulated rate option averages less than three cents per kilowatt-hour.

California regulators weigh whether the state needs more power plants

California Natural Gas Plant Rethink signals a shift toward clean energy, renewables, distributed solar, battery storage, and grid modernization as LADWP and regulators pause repowering plans amid an electricity oversupply and rising ratepayer costs.

 

Key Points

California pauses new gas plants to assess renewables, storage, and grid solutions for reliability.

✅ LADWP delays $2.2B gas repowers to study clean alternatives

✅ CEC weighs halting Oxnard plant amid grid oversupply

✅ Distributed solar, batteries, demand response boost reliability

 

California energy officials are, for the first time, rethinking plans to build expensive natural gas power plants in the face of an electricity glut and growing use of cleaner and cheaper energy alternatives.

The Los Angeles Department of Water and Power announced Tuesday that it has put a hold on a $2.2-billion plan to rebuild several old natural gas power plants while it studies clean energy alternatives to meet electricity demands. And the California Energy Commission may decide as early as Thursday to halt a natural gas project in Ventura County.

The scrutiny comes after an investigation found that the state is operating with an oversupply of electricity, driven largely by the construction of gas-fueled generating plants, leading to higher rates as regulators consider a rate overhaul to clean the grid. The state’s power plants are on track to be able to produce at least 21% more electricity than needed by 2020, according to the Times report.

Californians are footing a $40-billion annual bill while using less electricity, paying $6.8 billion more than they did in 2008 when power use in the state was at its all-time high. Electricity consumption has since fallen and remained largely flat.

Utilities in California have been on a years-long building binge, adding new natural gas plants even as the nation’s electricity system has undergone significant change, including consumer choice reforms that are reshaping the market.

Where utilities once delivered all electrical services from huge power plants along miles of transmission lines, the industry now must consider power delivered to the electric grid not only from its own sources, but also from solar systems and batteries at homes and businesses.

At the same time, utilities have been aggressively upgrading or rebuilding their aging natural gas plants — a move critics have said is unnecessary because consumers are using less power and clean energy technology is making those plants obsolete.

The DWP and energy commission moves involve as many as seven natural gas plant projects proposed for Southern California, despite warnings about a looming shortage if capacity is retired too fast, from Oxnard to Carlsbad, at a cost of more than $6 billion.

Reiko Kerr, the DWP’s senior assistant general manager of power systems, said given the changes in the energy world, the assessment is necessary to protect ratepayer dollars and the environment.

“The whole utility paradigm has shifted,” Kerr said in an interview. “We really are doing our ratepayers a disservice by not considering all viable options.

“We’re just looking at everything,” she said. “What can help us solve this reliability, renewable and greenhouse gas challenge that we all have?”

State and local governments have felt a heightened sense of urgency to deal with climate change after President Trump decided last week to withdraw the United States from the Paris climate accord.

California already has mandated that at least 50% of the state’s electricity come from clean energy sources by 2030. Senate leader Kevin de León (D-Los Angeles) wants to increase that to 100% by 2045.

Building or overhauling natural gas plants throughout Southern California, environmentalists argue, isn’t helping achieve those goals, even as some contend the state can't keep the lights on without gas during the transition.

The DWP’s move to delay plans for the fossil fuel plants, which seemed all but set to be built, came as a surprise to clean-energy advocates, who hailed the decision.

“This is a great first step toward smart energy investments that save customers money, ensure the lights stay on and protect our health and environment,” Graciela Geyer of the Sierra Club said.

The environmental group said that if the utility had moved ahead with the $2.2-billion investment in repowering natural gas plants, it “would have blown an irreparable hole in the city and the state’s hopes to achieve 100% generation” from clean energy sources.

Angela Johnson Meszaros, attorney at EarthJustice, said in a statement: "As our city struggles with the worst smog we’ve seen in years, we appreciate that LADWP is taking some much-needed time to reassess its plans to build fossil fuel power plants. We look forward to the day that LADWP announces that we are going to power our city with 100% clean energy.”

The gas-fired generating units slated for demolition and rebuilding are at the Scattergood, Haynes and Harbor electricity plants, which range from 34 to 67 years old.

As a group, the three plants have generated less than 20% of their combined capacity since 2001. The Harbor facility has operated on the low end at just 7%, while Haynes ran on the high end at 22%.

“The old model, the old legacy clunkers, won’t get us into the future we want,” DWP’s Kerr said.

DWP staff members told the utility’s’ commissioners Tuesday that their analysis of possible alternatives would be completed no later than early 2018.

Separately, the California Energy Commission this week is evaluating whether to halt a natural gas project in Ventura County after the state’s electric grid operator offered to conduct a study of clean energy alternatives to the roughly $250-million project on Mandalay Bay in Oxnard.

An energy commission committee has been deliberating since a hearing Monday during which Southern California Edison and the project’s developer, NRG Energy, argued that a study is simply a delay tactic that probably would kill a project needed to ensure reliable electric service and to avoid blackouts during peak demand.

The California Independent System Operator, which runs the state’s electric grid, told the energy commission that it would take three to four weeks to conduct its study on alternatives to the Oxnard natural gas project.

“Here we have an actual offer by the ISO to do such an analysis,” Ellison Folk, a lawyer representing the city of Oxnard, told the energy commission as she pushed for the study. “Its view that this is an analysis worth doing is something worth taking seriously.”

Energy commission members reviewing the study proposal are scheduled to meet again Thursday to consider the offer.

The board of governors for the California Independent System Operator made the unusual offer at its May 1 meeting to conduct a eleventh-hour study of clean-energy alternatives to building a new natural gas plant.

“If we’re going to be moving forward with a gas plant at this time, in this juncture, in the context of everything that’s going on, not evaluating other alternatives that are viable, noncombustion alternatives, is a missed opportunity,” Angelina Galetiva. a commission board member, said during the May 1 meeting.

Premier warns NDP, Greens that delaying Site C dam could cost $600M

Site C Project Delay raises BC Hydro costs as Christy Clark warns $600 million impact; NDP and Greens seek BCUC review of the hydroelectric dam on the Peace River, challenging evictions and construction contracts.

 

Key Points

A potential slowdown of B.C.'s Site C dam, risking $600M overruns, evictions, and schedule delays pending a BCUC review.

✅ Clark warns $600M cost if river diversion slips a year

✅ NDP-Green seek BCUC review; request to pause contracts, evictions

✅ Peace River hydro dam; schedule critical to budget, ratepayers

 

Premier Christy Clark is warning the NDP and Greens that delaying work on the Site C project in northeast British Columbia could cost taxpayers $600 million.

NDP Leader John Horgan wrote to BC Hydro last week asking it to suspend the evictions of two homeowners and urging it not to sign any new contracts on the $8.6-billion hydroelectric dam until a new government has gained the confidence of the legislature.

But Clark says in letters sent to Horgan and Green Leader Andrew Weaver on Tuesday that the evictions are necessary as part of a road and bridge construction project that are needed to divert a river in September 2019.

Any delay could postpone the diversion by a year and cost taxpayers hundreds of millions of dollars, she says.

“With a project of this size and scale, keeping to a tight schedule is critical to delivering a completed project on time and on budget,” she says. “The requests contained in your letter are not without consequences to the construction schedule and ultimately have financial ramifications to ratepayers.”

The premier has asked Horgan and Weaver to reply by Saturday on whether they still want to put the evictions on hold.

She also asks whether they want the government to issue a “tools down” request to BC Hydro on other decisions that she says are essential to maintaining the budget and construction schedule.

An agreement between the NDP and Green party was signed last week that would allow the New Democrats to form a minority government, ousting Clark's Liberals.

The agreement includes a promise to refer the Site C project to the B.C. Utilities Commission to determine its economic viability.

Some analysts argue that better B.C.-Alberta power integration could improve climate outcomes and market flexibility.

But Clark says the project is likely to progress past the “point of no return” before a review can be completed.

Clark did not define what she meant by “point of no return,” nor did she explain how she reached the $600-million figure. Her press secretary Stephen Smart referred questions to BC Hydro, which did not immediately respond.

During prolonged drought conditions, BC Hydro has had to adapt power generation across the province, affecting planning assumptions.

In a written response to Clark, Weaver says before he can comment on her assertions he requires access to supporting evidence, including signed contracts, the project schedule and potential alternative project timelines.

“Please let me express my disappointment in how your government is choosing to proceed with this project,” he says.

“Your government is turning a significant capital project that potentially poses massive economic risks to British Columbians into a political debate rather than one informed by evidence and supported by independent analysis.”

The dam will be the third on the Peace River, flooding an 83-kilometre stretch of valley, and local First Nations, landowners and farmers have fiercely opposed the project.

Construction began two years ago.

A report written by University of British Columbia researchers in April argued it wasn't too late to press pause on the project and that the electricity produced by Site C won't be fully required for nearly a decade after it's complete.
