Electric truck maths, fusion permits and China's cheap EVs: the grid bill comes due

Electric trucks already cost less to run than diesel in six of nine major EU markets, which together account for 46% of new heavy truck sales. That is the headline from a Transport & Environment (T&E) analysis published on 28 September. It lands the same week as two other events, all pointing at the same bottleneck: the wires, chargers and substations behind the vehicles.

T&E says savings reach up to 100,000 euros in the Netherlands and 85,000 euros in Germany over five years, with payback after two years. With current high diesel prices, it puts those figures at 123,000 euros and 106,000 euros respectively. The same modelling projects that by 2030 electric trucks will be cheaper to operate in all nine countries studied, even if purchase subsidies are phased out or reduced.

That is a claim about operating economics, not about vehicle supply. The two are not the same problem, and the second one is harder.

What the truck analysis actually says

The report names three levers: keeping the HDV CO2 standards, expanding CO2-based tolling, and continuing support for depot and public charging while accelerating grid upgrades and permitting. On tolling, T&E calls on Italy, France, Spain and Poland to implement the Eurovignette Directive and exempt zero-emission trucks from charges by 100% until 2031, then 50 to 75% afterwards. The -43% 2030 CO2 target is described as necessary to force manufacturers to offer more electric trucks and reach the economies of scale that bring prices down.

Stef Cornelis, director of freight and fleets at T&E, framed the choice bluntly. "There has never been a better time to switch from diesel to electric, but we need truckmakers and governments to support them in doing so," he said. He added that reintroducing fuel rebates "is the wrong answer to this crisis and will only prolong the transport sector's dependency on cripplingly expensive diesel."

He also warned about competition. "Maintaining the CO2 standards will be critical for Europe's truck industry to compete with Chinese e-trucks and the Tesla Semi and avoid a repeat of what we saw in the auto industry," Cornelis said. T&E notes that Chinese and US e-trucks are now being sold with a considerably lower purchase price. In Germany, that would mean 34,000 euros more in savings over five years.

Those numbers come from a campaign group with a stated zero-emission mission, not from a neutral auditor. The report is published alongside a new online cost-comparison tool. Treat the direction of travel as well evidenced and the exact euro figures as modelling.

The charging side is where it gets expensive

Ars Technica's 26 September piece on the Tesla Semi makes the counterpart argument. The long-range Semi is estimated at 500 miles per charge, the standard version at 325 miles, according to Lars Moravy, Tesla's vice president of Vehicle Engineering, speaking at the launch event in Sparks, Nevada. Competitor EVs advertise ranges of 155 to 430 miles. Electric semis can cost two to three times more upfront, and they need a countrywide network of specialised megawatt chargers.

Tesla's website showed two such public chargers operating in the LA area at the time of writing. Dan Priestley, who leads the Semi program, says the company plans to open 30 by the end of the year. That gap between two and 30 is the whole investment story in one line.

The demand signal, at least, is real. Ars Technica reports that an alliance of shippers including Microsoft and PepsiCo placed a record-setting order for 2,500 Tesla Semis, for delivery starting this year and through the next 18 months. If those trucks reach customers, they would nearly double the number of heavy-duty electric trucks on US roads today. Meena Bibra, a spokesperson for the nonprofit Smart Freight Centre, which was involved in the deal, told WIRED the group assessed "price, performance, production capability, and service support" before choosing Tesla. She said pooling demand among carriers helped bring prices down.

Context matters here. Electric trucks account for nearly 30 percent of heavy-duty truck sales in China, according to state media cited by Ars Technica, against a slow start in the US. The Trump administration cut billions in federal EV support last year and is working to lower fuel economy standards for truck engines. US diesel prices hit record highs this month, up nearly double year on year, as the Iran War disrupts Middle East oil production and shipping. Heavy trucks alone account for about 7 percent of US greenhouse gas emissions.

Musk, in a pre-taped address, said the truck "is going to make a ton of sense economically because the cost of electricity is much less than the cost of diesel, especially in these crazy times." He skipped the event itself, attending a White House China State Dinner instead, per Ars Technica. Full Self-Driving (Supervised) will not yet be available on the Semi; Musk said it would debut in "the very near future."

Fusion wants a grid connection too

Now move from trucks to generators, because the same interconnection queue is being asked to absorb something far less certain. TechCrunch reported on 28 September that Commonwealth Fusion Systems co-founder and chief science officer Brandon Sorbom and Helion founder and CEO David Kirtley will speak at TechCrunch Disrupt 2026, October 13 to 15 at Moscone West in San Francisco, in a session called "Bringing Fusion to the Grid."

The concrete facts behind that billing are sparse but checkable. CFS is building SPARC, a demonstration machine meant to pave the way for its first commercial plant, ARC. In April, CFS became the first fusion company to apply to PJM Interconnection, the largest US wholesale electricity market, a necessary step toward eventually connecting ARC to the grid. In July it raised another $1 billion, bringing total funding to $4 billion.

Helion is developing Orion, a 50-megawatt fusion plant intended to supply electricity to Microsoft beginning in 2028, with the company describing that timeline as "as early as 2028." In February, Helion announced that its Polaris prototype had heated plasma to 150 million degrees Celsius. In June it announced a key regulatory milestone on the path to building and operating the plant. Its Series G round, initially announced at $465 million in June, closed at $500 million in September.

Read those two paragraphs again and notice what is missing: no plant has delivered power to a customer. The PJM application is a queue position, not a connection. The 150 million degrees is a plasma result, not a megawatt-hour. Both companies are selling a schedule, and the grid operators they need are the same ones being asked to fund upgrades for trucks, data centres and everything else.

The cheap end of the market is moving fastest

Meanwhile the entry-level segment, where volumes actually are, keeps getting cheaper. CnEVPost reported on 28 September that FAW-Volkswagen's Jetta brand opened pre-sales for its M6 sedan in China, priced from 80,800 yuan to 99,800 yuan, or about 11,990 dollars at the low end. The M6 is Jetta's first battery electric model and is scheduled for an official launch in mid-October.

Three variants are listed: 465 Pro, 555 Max and 555 Ultra, with the numbers indicating CLTC range in kilometres. The car is built on Jetta's in-house Jiesi architecture and a dedicated EV platform, with a single-motor, front-wheel-drive layout, two motor options at 113 kW and 145 kW, and batteries supplied by CALB (HKEX: 3931). It measures 4,806 mm long, 1,868 mm or 1,895 mm wide and 1,500 mm tall, on a 2,820 mm wheelbase, with a 15.6-inch 2.5K central touchscreen and Horizon Robotics' Journey 6M chip running a vision-only highway and urban NOA system.

Jetta is targeting the entry-level EV market around 100,000 yuan and plans five new models by 2028, four of them new energy vehicles, with a medium-term target of 400,000 to 500,000 vehicles in annual production and sales. FAW-Volkswagen set up FAW Volkswagen Jetta Automotive Technology Co Ltd in Chengdu, Sichuan province, in January, giving the brand more autonomy. Pre-sales benefits are listed at about 11,000 yuan.

None of these three stories mentions substations, transformers or grid connection queues in the same breath as its product. That is the analysis: the vehicles and the power plants are both being priced on the assumption that the electricity arrives. The evidence that it will, at the speed the sales forecasts require, is not in any of these documents.
