You almost never see them, yet they pass under your skis every night. Snow groomers account for a significant share of a ski area’s fuel consumption. This winter, three French resorts are hosting the first series-produced high-power electric groomer.
A machine born of a partnership
The Leitwolf LTE-Motion comes from a 2024 agreement between Italian manufacturer Prinoth and Compagnie des Alpes. It was unveiled on 21 April 2026 in Grenoble during the Mountain Planet trade show.
Assembled in Montmélian
The dedicated assembly line sits in Montmélian, Savoie, inside the Prinoth France buildings. Some parts are sourced locally and the batteries are produced and assembled in Europe.
What it actually changes
Three things, and carbon is only the first. Because Compagnie des Alpes buys renewable electricity, going electric removes up to 93% of emissions compared with a groomer running on HVO 100.
The second is invisible in reports but not to residents: noise. Grooming happens at night, often right next to villages. An electric machine removes the diesel rumble and the fine particles that come with it.
The third is economic: 53% lower annual operating costs against an HVO 100 machine, and around 20% on maintenance. That is what makes the case work despite a purchase price roughly four times higher.
The limits
Stated range is four to five hours in normal conditions, extendable to a seven-hour shift through fast charging during the driver’s break. On paper that is enough; the test season has to confirm it on steep ground at minus fifteen. Electrification also covers the drivetrain only for now; the tiller and accessories come later.
Three resorts, one test winter
Three pre-series machines enter service this autumn at Serre Chevalier, La Plagne and Val d’Isère. Wider commercial release is announced for 2027-2028. Full press release here.
