UNVEILING THE LEITWOLF LTE-MOTION

PRINOTH AND COMPAGNIE DES ALPES PIONNEER THE ERA OF 100% ELECTRIC HIGH-POWER SNOW GROOMING

Grenoble, 21 April 2026 – PRINOTH, the world's pioneering snow groomer manufacturer, and Compagnie des Alpes (CDA), the leading ski resort operator, are marking a historic milestone with the unveiling of the LEITWOLF LTE-Motion. This high-power electric snow groomer is the first in the world capable of meeting the performance demands of alpine skiing while being manufactured at industrial scale. This launch is the tangible outcome of the strategic partnership established in 2024, aimed at industrializing the production of high-power electric snow groomers within Alpine territories and thereby achieving carbon neutrality in slopes maintenance operations.

A Technological Breakthrough: Power Without Emissions

Designing an electric snow groomer capable of replacing a high-power combustion-engine model represented a considerable engineering challenge. The LEITWOLF LTE-Motion rises to that challenge by delivering performance equivalent to that of the standard diesel version. The key innovation lies in the low-mounted positioning of European-manufactured batteries, lowering the centre of gravity to ensure both stability and hill-climbing capability. To withstand the constraints of high-altitude operations, a purpose-built thermal management system maintains all components within an optimal temperature range. This technology delivers an operating range of 4 to 5 hours under standard conditions, extendable to a full 7-hour shift through rapid charging during the operator's break.

In the case of CDA, which operates under a renewable energy supply contract, switching to electricity reduces emissions by 93% compared with a snow groomer running entirely on HVO 100¹. With no diesel engine or high-pressure hydraulic circuits for machine propulsion, maintenance costs are reduced by a minimum of 20%, and the energy efficiency gains are such that an electric snow groomer costs approximately twice less per year to operate than its combustion-engine counterpart². These economic benefits are compounded by an immediate environmental dividend: the complete absence of fine particulate emissions and near-silent operation.

A Sovereign Choice: An Assembly Line and Industrial Roll-Out at the Heart of the Alps

Beyond machine performance, this partnership is distinguished by a strong commitment to reshoring. At Compagnie des Alpes' request, PRINOTH is establishing a dedicated assembly line in Montmélian, Savoie, as of this year. By locating this production within the PRINOTH France facility, both partners are making a deliberate regional development choice, involving locally sourced components and batteries manufactured and assembled in Europe. This strategic decision guarantees essential industrial sovereignty and supports local employment in line with the assembly line's ramp-up, creating an ecosystem in which innovation is produced in the very territories where it is deployed.

From autumn 2026, the first three LEITWOLF LTE-Motion units will enter service at Serre Chevalier, Val d'Isère (Bonneval-sur-Arc sector), and La Plagne. Operational feedback from CDA teams will be instrumental in finalizing the last technical adjustments. Global sales have begun, and first deliveries will take place before the 2027–2028 season. By committing to transitioning its fleet (around 100 equivalent machines) over a 10-year horizon, Compagnie des Alpes provides the long-term visibility required to drive transformation across the entire snow grooming industry.

Executive Statements

Dominique THILLAUD, Chief Executive Officer of Compagnie des Alpes:

"With the LEITWOLF LTE-Motion, we are giving concrete expression to our corporate mission by radically decarbonising snow grooming — our primary source of residual emissions (Scope 1 & 2) across our ski resorts. This project goes beyond technology: by calling for an assembly line in Montmélian, we are anchoring innovation at the heart of our valleys. This is an act of industrial sovereignty that demonstrates operational excellence and ecological transition are inseparable. Furthermore, the progressive electrification of our groomer fleet also enables us to better control the availability and cost of the energy we consume."

Anton SEEBER, CEO of High Technology Industries:

"This partnership with Compagnie des Alpes accelerates our ambition to deliver zero-emission solutions perfectly suited to extreme operating conditions. By combining PRINOTH's technological expertise with Compagnie des Alpes' field experience, we are industrialising a high-power electric machine with absolutely no compromise on performance."
