Bergbahnen Wilder Kaiser put an emphasis on sustainability measures

A fair and thriving collaboration with the local farmes and landowners, the perfect adaption to natural circumstances at Hartkaiser or technical innovations when it comes to the extension of the water reservoirs: a lot of things are done in order to improve the overall experience at Bergbahnen Wilder Kaiser.
Klaus Exenberger, CEO: "By expanding thephotovoltaic system on all roofs of the valley station, the top station and the hotel, energy costs of the facilities can be reduced by 50% in the future."

Innovation: Construction with clear economic goals and a focus on minimizing the carbon footprint

By expanding the water reservoirs, the company does not only secure the quality of the skiing experience, but also offers new perspectives and an additional use of the reservoir on the mountain in the summer seasons.

Facts of the activities

Expansion of the snow plant and pumping stations:

- Expansion of the water reservoir Hartkaiser from 80,000m³ to roughly 140,000m³
- Expansion of the water reservoir Tanzboden from 125.000m³ to roughly 160,000m³

Furthermore, the pumping capacity at Hartkaiser was increased from 280 liters per second to 780 liters per second and the Weiters wird die Pumpleistung am Hartkaiser von derzeit 280 lt/s auf 780 lt/s and the cooling power was raised to 70%! The snowmaking time is thereby reduced from 8 days to 4 days. This ensures more operation security (skiing) for the touristic region.

Further steps

The flowline systems was expanded by roughly 5.50km: biger pipes, reduction of the flow speed and installing new snow guns (total amount now: 50). This way, savings of 5 - 8 KW per snow gun are possible. The expanded reservoir holds the melting snow in spring and saves it for the next winter. This reduction of energy and water usage leads to a much lower carbon footprint. By optimizing the hydraulic system of the pumping station further advantages are created: More inherent pressure effects energy savings when it comes to snow making and also reduces the amount of snow making hours. This leads to less stress for the energy network.
