UK EV Grid Capacity leverages smart charging, V2G, renewable energy, and interconnectors to manage peak demand as adoption grows, with National Grid upgrades, rapid chargers, and efficiency gains enabling a reliable, scalable charging infrastructure nationwide.

Key Points

UK EV grid capacity is the power network's readiness to meet EV demand using smart charging, V2G, and upgrades.

✅ Smart charging shifts load to off-peak, cheaper renewable hours

✅ V2G enables EVs to supply power and balance peak demand

✅ National Grid upgrades and interconnectors expand capacity

The surge of electric vehicles (EVs) on our roads raises a crucial question: can the UK's electricity grid handle the additional demand? While this is a valid concern, it's important to understand the gradual nature of EV adoption, ongoing grid preparations, and innovative solutions being developed.

A Gradual Shift, Not an Overnight Leap

Firstly, let's dispel the myth of an overnight transition. EV adoption will unfold progressively, driven by factors like affordability and the growing availability of used models. The government's ZEV mandate outlines a clear trajectory, with a gradual rise from 22% EV sales in 2024 to 80% by 2030. This measured approach allows for strategic grid improvements to accommodate the increasing demand.

Preparing the Grid for the Future

Grid preparations for the EV revolution have been underway for years. Collaborations between the government, electricity providers, service stations, and charging point developers are ensuring grid coordination across the system. Renewable energy sources like offshore wind farms, combined with new nuclear power and international interconnections, are planned to meet the anticipated 120 terawatt-hour increase in demand. Additionally, improvements in energy efficiency have reduced overall electricity consumption, creating further capacity.

Addressing Peak Demand Challenges

While millions of EVs charging simultaneously might seem like they could challenge power grids, solutions are being implemented to manage peak demand:

1. Smart Charging: This technology allows EVs to charge during off-peak hours when renewable electricity is abundant and cheaper. This not only benefits the grid but also saves owners money. The UK government's EV Smart Charge Points Regulations ensure all new chargers have this functionality.

2. Vehicle-to-Grid (V2G) Technology: This futuristic concept transforms EVs into energy storage units, often described as capacity on wheels, allowing owners to sell their unused battery power back to the grid during peak times. This not only generates income for owners but also helps balance the grid and integrate more renewable energy.

3. Sufficient Grid Capacity: Despite concerns, the grid currently has ample capacity. The highest peak demand in recent years (62GW in 2002) has actually decreased by 16% due to energy efficiency improvements. Even with widespread EV adoption, the expected 10% increase in demand remains well within the grid's capabilities with proper management in place.

National Grid's Commitment:

National Grid and other electric utilities are actively involved in upgrading and expanding the grid to accommodate the clean energy transition. This includes collaborating with distribution networks, government agencies, and industry partners to ensure the necessary infrastructure (wires and connections) is in place for a decarbonized transport network.

Charging Infrastructure: Addressing Anxiety

The existing national grid infrastructure, with its proximity to roads and train networks, provides a significant advantage for EV charging point deployment. National Grid Electricity Distribution is already working on innovative projects to install required infrastructure, such as:

• Bringing electricity networks closer to motorway service areas for faster and easier connection.
• Leading projects like the Electric Boulevard (inductive charging) and Electric Nation (V2G charging) to showcase innovative solutions.
• Participating in the Take Charge project, exploring new ways to facilitate rapid EV charging infrastructure growth.

Government Initiatives:

The UK government's Rapid Charging Fund aims to roll out high-powered, open-access charge points across England, while the Local EV Infrastructure Fund supports local authorities in providing charging solutions for residents without off-street parking, including mobile chargers for added flexibility.

While the rise of EVs presents new challenges, the UK is actively preparing its grid and infrastructure to ensure a smooth transition. With gradual adoption, ongoing preparations, and innovative solutions, the answer to the question Will electric vehicles crash the grid? is a resounding yes. The future of clean transportation is bright, and the grid is ready to power it forward.

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.

US Wind and Solar Outlook 2026 projects cheap renewables displacing coal and gas, with utility-scale additions, rooftop solar growth, improved grid reliability, and EV V2G integration accelerating decarbonization across the electricity market.

Key Points

An analysis forecasting wind and solar growth, displacing coal and gas as utility-scale and rooftop solar expand.

✅ Utility-scale solar installs avg 21 GW/yr through 2026.

✅ 37.7 GW wind in pipeline; 127.8 GW already online.

✅ Small-scale solar could near 100 TWh in 2026.

A recent report from the Institute for Energy Economics and Financial Analysis (IEEFA) predicts that cheap renewables in the form of wind and solar will push coal and gas out of the energy market space. Already at 9% of US generation, the report predicts that wind and solar will supply almost 30% of US electricity demand by 2026, consistent with renewables nearing one-fourth of U.S. generation projections for the near term.

“The Solar Energy Industries Association now expects utility-scale installations to average more than 21,000MW a year through 2026, following a year when U.S. solar generation rose 25% and with a peak of 25,000MW in 2023,” IEEFA writes. “Continued growth is also expected in U.S. wind generation, mirroring global trends where China's solar PV expansion outpaced all other fuels in 2016, with 37.7GW of new capacity already under construction or in advanced development, which would be added to 127.8GW in existing installed capacity.”

Meanwhile, with wind and solar growth booming, fossil fuels are declining, as renewables surpassed coal in 2022 nationwide. “Coal and natural gas are now locked into an essentially zero-sum game where increases in one fuel’s generation comes at the expense of the other. Together, they are not gaining market share, rather they are trading it back and forth, and the rapid growth in renewable generation will cut even deeper into the market share of both.”

And what of rooftop solar? Some states in Australia now have periods where the entire state grid is powered just by solar on the roofs of private citizens. As this revolution progresses in the USA, especially if a tenfold national solar push moves forward, what impact will it make on fossil fuel generators — which are expensive to build, expensive to maintain, expensive to fuel, and rely on an expensive distribution network.

“EIA estimates that this ‘small-scale solar’ produced 41.7 million MWh of power in 2020, when solar accounted for about 3% of U.S. electricity, a 19 percent increase from 2019. This growth will likely continue in the years ahead as costs continue to fall and concerns about grid reliability rise. Assuming a conservative 15 percent annual increase in small-scale solar going forward would push the sector’s generation to almost 100 million MWh in 2026.”

The Joker in the story might be the impact from electric vehicle adoption. Sales are set to surge and there’s more and more interest in V2G technology, even as wind and solar could provide 50% by 2050 in broader forecasts.

Arizona Electric Vehicle Ownership is surging, led by EV adoption, charging stations growth, state incentives, and local manufacturers; yet rural infrastructure gaps and limited fast-charging plugs remain key barriers to convenient, statewide electrification.

Key Points

Arizona Electric Vehicle Ownership shows rising EV adoption and incentives, but rural fast-charging access still lags.

✅ 28,770 EVs registered; sixth per 1,000 residents statewide

✅ 385 fast chargers; 1,448 Level 2 plugs; many not 24/7

✅ Incentives: lower registration, HOV access, utility rebates

For a mostly red state, Arizona has a lot of blue-state company when it comes to states ranked by electric vehicle ownership, according to recent government data.

Arizona had 28,770 registered electric vehicles as of June, according to the U.S. Department of Energy's Alternative Fuels Data Center, the seventh-highest number among states. When ownership is measured per 1,000 residents, Arizona inches up a notch to sixth place, with just over four electric vehicles per 1,000 people.

That rate put Arizona just behind Oregon and Colorado and just ahead of Nevada and Vermont. California was in the lead by far, with California's EV and charging lead reflected in 425,300 registered electric vehicles, or one for every 10.7 residents.

Arizona EV enthusiasts welcomed the ranking, which they said they have seen reflected in steady increases in group membership, but said the state can do better, even amid soaring U.S. EV sales this year.

"Arizona is growing by leaps and bounds in major areas, but still struggling out there in the hinterlands," said Jerry Asher, vice president of the Tucson Electric Vehicle Association.

He and others said the biggest challenge in Arizona, as in much of the country, is the lack of readily available charging stations for electric vehicles.

Currently, there are 385 public fast-charging plugs and 1,448 non-fast-charging plugs in the state, where charging networks compete to expand access, said Diane Brown, executive director with the Arizona Public Interest Research Group Education Fund. And many of those "are not available 24 hours a day, often making EV charging less convenient to the public," she said.

And in order for the state to hit 10% EV ownership by 2030, one scenario outlined by Arizona PIRG, the number of charging stations would need to grow significantly.

"According to the Arizona PIRG Education Fund, to support a future in which 10% of Arizona's vehicles are EVs – a conservative target for 2030 – Arizona will need more than 1,098 fast-charging plugs and 14,888 Level 2 plugs," Brown said.

This will require local, state and federal policies, as EVs challenge state power grids, to make "EV charging accessible, affordable, and easy," she said.

But advocates said there are several things working in their favor, even as an EV boom tests charging capacity across the country today. Jim Stack, president of the Phoenix Electric Auto Association, said many of the current plug-ins charging stations are at stores and libraries, places "where you would stop anyway."

"We have a good charging infrastructure and it keeps getting better," Stack said.

One way Asher said Arizona could be more EV-friendly would be to add charging stations at hotels, RV parks and shopping centers. In Tucson, he said, the Culinary Dropout and Jersey Mike's restaurants have already begun offering free electric vehicle charging to customers, Asher said.

While they push for more charging infrastructure, advocates said improving technology and lower vehicle expenses are on their side, as post-2021 electricity trends reshape costs, helping to sway more Arizonans to purchase an electric vehicle in recent years.

"The batteries are getting better and lower in cost as well as longer-lasting," Stack said. He said an EV uses about 50 cents of electricity to cover the same number of miles a gas-burning car gets from a gallon of gas – currently selling for $3.12 a gallon in Arizona, according to AAA.

In addition, the state is offering incentives to electric vehicle buyers.

"In AZ we get reduced registration on electric vehicles," Stack said. "It's about $15 a year compared to $300-700 a year for gas and diesel cars."

Electric vehicle owners also "get 24/7 access to HOV lanes, even with one person," he said. And utilities like Tucson Electric Power offer rebates and incentives for home charging stations, according to a report by the National Conference of State Legislatures, and neighboring New Mexico's EV benefits underscore potential economic gains for the region.

Stack also noted that Arizona is now home to three eclectic vehicle manufacturers: Lucid, which makes cars in Casa Grande, Nikola, which makes trucks in Phoenix and Coolidge, and Electra Meccanica, which plans to build the three-wheeled SOLO commuter in Mesa.

"We get clear skies. No oil changes, no muffler work, no transmission, faster acceleration. No smog or smog tests," Stack said. "It's priceless."

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

Key Points

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

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

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

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

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

The Northwest Territories is hoping to change that.

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

China EV Market sees surging deliveries as Tesla, XPeng, Nio, and Li Auto race for market share, driven by tech-forward infotainment, autonomous features, and strong P7 and G3 demand, signaling intensifying competition and rapid growth.

Key Points

China EV Market features rapid EV sales growth led by Tesla, XPeng, Nio, and Li Auto amid tech-driven competition.

✅ XPeng deliveries up 617% YoY in June; 459% YTD growth

✅ Nio and Li Auto post triple-digit quarterly gains

✅ Tech focus: infotainment, ADAS; models P7, G3, G3i

XPeng President and Vice Chairman Brian Gu is quick to praise the Tesla brand and acknowledge the EV maker's "commanding" market share in China, and in key markets like the California EV market as well. 

But in the same breath, the executive at the upstart China-based EV rival said his company and peers are fast closing the competitive gap with Tesla.

"I think the Chinese players are catching up very quickly," Gu said on Yahoo Finance Live. "Our product as well as some of the other products that are being introduced by the leading players are very good, and have comparable specs — as well as better features I think compared to Tesla."

That point is not lost in the sales data from the main China EV players, and mirrors the global EV surge seen in recent years.

XPeng said this week deliveries in June surged 617% year-over-year to 6,565. So far this year, deliveries have skyrocketed 459% to 30,738 fueled by demand for XPeng's P7 sedan and G3 SUV, despite concerns about the biggest threats to the EV boom among investors. 

June deliveries at Nio rose 116% from a year ago to 8,083, even as mainstream adoption hurdles remain industry-wide. For the quarter ending June 30, Nio delivered 21,896 vehicles marking a growth rate from a year ago of 112%. 

As for Li Auto, its June deliveries rose 321% from a year earlier to 7,713. Second quarter deliveries improved 166% year-over-year to 17,575.

Tesla reportedly sold 33,155 cars in China in June, up 122% year-over-year, even as its energy business outlook remains a focus for investors. 

"In the last few months, our growth has outpaced the industry as well as Tesla in China. But I think it's a long race because ultimately this market will not be dominated by one or two companies. It will probably be a number of players occupying probably large market share positions of 10% and above. That will likely be the trend, and we hope to be one of those top players," Gu explained. 

XPeng — which JPMorgan analysts estimate could grab 8% of China's electric car market by 2025 —currently has two models in the Chinese electric car market, as China's carmakers push into Europe too. They have gained notoriety in an increasingly crowded market for their tech-forward infotainment systems and autonomous technology.

The company's third model dubbed the G3i is expected to see deliveries begin in September, taking aim at smaller sedans such as the Toyota Camry. 

Shares of China's EV makers have cooled off this year despite their strong sales, and the U.S. EV market share dipped in early 2024 as well. XPeng shares are down 7% year-to-date, while Nio has shed 5%. Li Auto's stock is down 11% on the year.
