Electric bus fleets scale up as Delhi cuts grid losses and EU truck maths shifts

The SWITCH Mobility order, first reported on 28 September, covers 840 electric buses for Delhi public transit under India's PM E-Drive scheme, with the buyer named as Antony Road Transport Solutions. Multiple Indian outlets carried the same figure within hours of each other, including Autocar Professional, Coach Builders India, Entrepreneur India and ACKO Drive, and the order is the most recent fleet-scale development in the dossier.

It lands in a city whose power grid has already been through a harder test. IEEE Spectrum's 29 September feature, written by a Delhi resident and published in the magazine's October 2026 issue, describes a city where outages in 2002 were frequent enough that a school run could collapse around them, and where the same network now reports aggregate losses near 5 percent, down from about 50 percent.

Why Delhi's grid number matters for buses

That is not a bus story on its face. It is a bus story in practice. Electric bus deployment is a charging problem before it is a vehicle problem, and charging economics depend on how much power is lost between the generator and the depot.

IEEE Spectrum does not put a figure on how much of the improvement flowed into transport, and the piece is a first-person magazine feature rather than a utility filing, so the 50-to-5 comparison should be read as the publication's own account rather than a regulator's audit. What the dossier does support is the direction of travel. A city that once lost half its power to the network has far more headroom for depot charging than one still losing 30 percent. The buses themselves are only half the equation.

"The roadmap's call for 7,300 charging stations by 2028 remains the most fragile link in the transition," CleanTechnica's op-ed on the Philippine Electric Vehicle Summit states.

That line comes from an op-ed published on 29 September and written by Raymond Tribdino. It is about the Philippines, not India, but the diagnosis travels. The 14th Philippine Electric Vehicle Summit opens in October, and the piece frames the event as an operational audit of the Department of Energy's Comprehensive Roadmap for the Electric Vehicle Industry, known as CREVI, which sits under the Electric Vehicle Industry Development Act, Republic Act 11697.

The statutory numbers are concrete: 311,700 electric vehicles registered and 7,300 dedicated charging stations deployed nationwide by 2028, on the way to 50 percent fleet electrification by 2040 under the government's clean energy scenario. With the 2028 deadline two years out, the op-ed argues that passenger car sales cannot deliver that volume and that light commercial platforms, including two-wheelers, three-wheelers, delivery vans and modernized electric public utility vehicles, have to carry it.

The EU cost case, and where it breaks

In Europe the argument has moved from ambition to arithmetic. A Transport & Environment total cost of ownership analysis published by CleanTechnica on 28 September finds that in six of nine major EU truck markets, electric trucks are already the cheapest financial choice, and those six markets account for 46 percent of all new heavy trucks sold in the EU.

The savings over five years reach 100,000 euros in the Netherlands, 85,000 euros in Germany and 69,000 euros in Denmark, according to the same analysis, with payback after two years. Running a Chinese-built truck, which carries a lower sticker price, pushes five-year savings to as much as 128,000 euros in the Netherlands. T&E attributes the shift to scale, lower truck prices driven by the EU's truck CO2 targets, national vehicle subsidies and lower road tolls.

Those are truck numbers, not bus numbers, and the dossier does not contain an equivalent bus TCO study. But the policy levers T&E names are the same ones that move bus fleets: purchase subsidies, toll treatment and, most importantly, the direction of charging costs. T&E's modelling, as reported, has electric trucks cheaper to operate across all nine EU member states by 2030 even if today's purchase subsidies are phased out or reduced, provided the Eurovignette Directive and RED III are implemented.

The specific asks are narrow. Maintain the EU truck CO2 standard's 43 percent reduction target for 2030. Implement CO2-based tolling so Italy, France, Spain and Poland exempt zero-emission trucks from road infrastructure charges, at 100 percent until 2031 and 50 to 75 percent afterwards. Enable RED III e-credits for depot charging in Sweden, France, Poland, Italy and Spain. Depot charging is where most trucks charge, and the same logic holds for buses that return to a yard overnight.

Efficiency is the quiet variable

Hannah Ritchie's 29 September Substack post, citing work by Oxford professor Nick Eyre, puts a number on the efficiency side of the ledger. Under a post-transition system where suitable sectors are electrified and the rest run on hydrogen, global final energy demand falls from 416 exajoules to 247 exajoules, while electricity demand rises from 110 to 189 exajoules. Electricity moves from about one-quarter of final energy demand to about three-quarters.

The transport detail is blunt: electric vehicles are around four times as efficient as petrol, with about 20 percent of energy converted to motion in a petrol car against around 80 percent in an electric one, subject to variation from regenerative braking. Post-transition energy demand for cars and vans is about one-quarter of current demand in the model. The author is explicit that this is a simplistic model and that it holds other efficiency gains constant, so the reduction is likely understated rather than overstated. Buses are modelled at 80 percent electrified, with only long-distance buses on hydrogen.

None of this makes fleet conversion automatic. The Philippine op-ed notes that government agencies and commercial cargo operators must ensure electric vehicles make up at least five percent of their operational fleets under the development act, and that premium SUVs and executive sedans dominate distributor marketing budgets while volume lives in commercial platforms. That is a mismatch between where the marketing money goes and where the statutory targets have to be met.

Volkswagen, meanwhile, is consolidating its electric naming around an established badge. A press release carried by CleanTechnica on 29 September confirms the ID. Tiguan will premiere in early October and reach markets at the beginning of 2027, succeeding the ID.4 and ID.5 and selling alongside the combustion and hybrid Tiguan. Volkswagen brand CEO Thomas Schäfer is quoted saying more than 8.3 million Tiguan vehicles have been produced, and the release says Tiguan and Tayron deliveries exceeded one million units in the past year while ID.4 and ID.5 have delivered more than 950,000 units since 2021.

That is a passenger car story, but it speaks to the same manufacturing question the bus market faces: whether established nameplates and platforms can be carried into electric volume without losing the cost base that made them sell.

What to watch

The charging count is the number to track. The Philippine roadmap needs 7,300 stations by 2028 and, as the op-ed notes, the count as of mid-2026 was not where it needed to be. Delhi's grid has already done the harder work of cutting losses. The EU has a cost case that T&E says holds in six of nine major truck markets today and could hold in all nine by 2030.

Against that, Tesla's fan-car patents, granted on 29 September and reported by Electrek, are a reminder that not every electric vehicle headline is about fleets. The USPTO granted US 12,746,987 B1 for an electric fan car with four ducted fans in the rear diffuser, filed in January 2024 and tracing back to a January 2023 provisional. The drawings show a Model S, which Tesla stopped building in April. Eight inventors are listed. It is Tesla's second fan-car patent in just over a year, and the only performance car left in its pipeline is the Roadster.

For transit operators, the useful signal is duller and more consequential: buses ordered, chargers built, power delivered. The 840-bus Delhi order and the 50-to-5 grid loss figure are the two halves of that story, and only one of them has a delivery date.
