The Netherlands is what happens when subsidy design is executed by people who understand fleet economics. The 2025 result — 2,025 electric truck registrations, +200% year-on-year, the fastest growth of any large EU market — was engineered, not accidental, and the 2026 toolbox is stronger still.

AanZET: the purchase lever. The AanZET scheme pays up to €115,200 per zero-emission truck depending on weight class. The 2026 first round opened 27 January with €78 million; a second application window opens 29 September 2026, and the current round’s applications run to 7 May 2027 or budget exhaustion — first-come processing makes early filing the whole game. Eligibility requires a Dutch-registered buyer, an RVO-listed zero-emission vehicle and a binding purchase agreement at application. Practical consequence: vendor selection and board approval must finish before the window opens, not after.

The toll lever. On 1 July 2026 the vrachtwagenheffing replaced the old Eurovignette regime with a distance-based, CO₂-graded truck toll on motorways and selected national roads: zero-emission ≈ €0.038/km, Euro VI diesel ≈ €0.204/km. Combined with the same-day Flemish charge, the entire Antwerp–Rotterdam–Ruhr freight system now prices carbon by the kilometre. At 150,000 km/year, the toll gap alone approaches €25,000 per truck annually.

Stack arithmetic. Grant (up to €115,200 once) plus toll gap (~€25,000/year) plus depot energy at Dutch industrial tariffs puts a well-utilised Dutch electric tractor ahead of diesel on five-year TCO by a six-figure margin in favourable duty cycles. The constraints are the usual two: grid connection lead times at congested Dutch substations, and residual-value uncertainty for a vehicle class with no used market yet. Leasing companies are actively pricing the second risk; expect guaranteed-buyback structures to spread through 2026–27.

WattTonne’s read. If your group contains a Dutch entity, the September window is a hard calendar item: file prepared by mid-September. For cross-border fleets, registering where the kilometres and the grant are is not arbitrage — it is reading the policy map the way its authors intended.
