Austria’s Tyrol region has reached a milestone in public transport electrification with the commissioning of a 2.4-megawatt electric bus depot by operator Ledermair. Located in one of Europe’s most challenging alpine environments, the facility is equipped with 28 Kempower charging points powered by four Kempower Power Units, designed to meet the demands of mountainous terrain and seasonal energy fluctuations.
Capacity and Technical Specifications
The depot’s 2.4 MW total charging capacity is distributed across 28 Kempower charging points, providing sufficient power to support the region’s growing electric bus fleet. The system incorporates scheduled charging and battery preconditioning—features that optimize energy use and reduce operational costs. According to Alexander Ledermair, Managing Director of Ledermair, these capabilities ensure "grid-optimized charging processes" while enhancing efficiency for the regional public transportation network.
The infrastructure was installed by Austrian partner vlotte, which selected Kempower’s modular hardware to address spatial constraints at the depot. Philipp Österle, Managing Director of vlotte, emphasized the flexibility of Kempower’s design, stating that competing solutions were "unsuitable for the specific spatial requirements" of the site. The system’s scalability allows for future expansion: each of the four Kempower Power Units can be upgraded to 600 kW, and the depot can accommodate up to 32 charging points without structural changes.
Operational Efficiency and Grid Integration
Charging operations are managed through ChargEye, Kempower’s cloud-based platform, which enables real-time monitoring and dynamic load distribution. This functionality is critical in Tyrol, where energy demand varies significantly due to tourism peaks and winter conditions. Alexander Ledermair confirmed that the charging systems are "performing superbly in daily operation," highlighting Kempower’s "excellent safety features and reliability" as key factors in the technology’s selection.
The depot’s modular design ensures adaptability for future fleet growth, aligning with broader trends among European transit operators seeking solutions for high-altitude or remote depots. While the exact number of electric buses currently served by the depot has not been disclosed, the 2.4 MW capacity suggests support for a fleet of 20–30 vehicles, depending on battery specifications and charging schedules.
Regional and Industry Implications
The Tyrol depot sets a precedent for electric bus infrastructure in mountainous regions, where cold temperatures and steep gradients increase energy consumption. Battery preconditioning—a process that adjusts battery temperature before charging—reduces energy waste and extends battery lifespan, addressing challenges unique to alpine climates. This approach supports Austria’s national target to electrify 50% of public transport buses by 2030, a goal that requires robust and adaptable charging solutions.
Vlotte’s role in the project underscores the growing expertise of regional firms in deploying high-power charging networks. Österle attributed the project’s smooth execution to vlotte’s prior experience, noting that the systems were installed "quickly and without any problems." The collaboration between Ledermair, vlotte, and Kempower demonstrates the importance of localized partnerships in overcoming geographic and technical barriers to fleet electrification.
