Liebherr's Battery Energy Storage System Enhances Avalanche Safety in Austria






The Austrian Torrent and Avalanche Control Centre has implemented a cutting-edge battery energy storage system (BESS) developed by Liebherr. This system is crucial for powering the construction of consolidation barriers, vital infrastructure that shields Austrian communities from the dangers of avalanches and landslides during the winter months. This innovative approach aims to significantly reduce emissions on construction sites, moving away from conventional diesel generators, and ensuring a reliable, eco-friendly power source for heavy machinery and site facilities.
Nikolaus Wieser, a civil engineer and site manager at the Austrian Torrent and Avalanche Control Centre, highlighted the environmental benefits of adopting this new technology. While traditional diesel generators have long been the standard for powering such remote construction sites, the Centre is committed to reducing its carbon footprint. The Liebherr solution provides an effective alternative, demonstrating a progressive shift towards more sustainable practices in civil engineering projects, particularly in environmentally sensitive alpine regions.
Liebherr, renowned for its formidable mining excavators and heavy-duty haul trucks, has also established itself as a leader in off-highway battery electric vehicle technology. This expertise has directly contributed to the development of advanced battery energy storage and DC fast-charging systems. Some of these charging systems boast an impressive 6MW of power, capable of rapidly energizing large electric equipment. This technological prowess makes Liebherr an ideal partner for projects requiring robust and efficient power solutions in challenging environments.
The mobile LPO 100 BESS, with a capacity of 94 kWh, is specifically designed to meet the energy demands of the construction site. It powers a Liebherr 34 K fast-erecting crane and various other tools and facilities, including container units, battery-operated devices, circular saws, and a water pump. A key feature of the system is its ability to buffer the fixed power connection on-site. This allows the system to cover the crane's peak energy requirements, which can reach up to 100 kVA, by discharging stored energy quickly when needed. During periods of lower demand, the batteries are trickle-charged using grid power and solar energy, effectively eliminating the need for a conventional diesel or gas generator.
Project leaders like Wieser have expressed satisfaction with the system's performance, noting its seamless installation and reliable operation. This successful deployment underscores the potential of battery energy storage systems to revolutionize construction practices, especially in locations where traditional power sources are either unavailable, inefficient, or environmentally detrimental. The transition to such systems represents a significant step towards decarbonizing heavy construction and off-highway vehicle operations globally.
The implementation of Liebherr's battery energy storage system is a testament to the increasing demand for sustainable power solutions in the construction sector. It highlights how understanding power needs and leveraging advanced battery technology can lead to more efficient, quieter, and emission-free operations. This initiative in Austria not only safeguards communities from natural disasters but also sets a precedent for environmentally responsible construction, fostering a safer and greener future.
