Water runs down to the Grubbach power plant over a two-kilometer-long pipeline. The power plant is inconspicuous, consisting of an engine room with control panel in a small operation building off the path. In that room, a significant contribution is made to the sustainable cycle on the Kitzsteinhorn, as explains Head of Snow Making, Peter Leo: "The Grubbach pumped storage hydropower plant was built in 2012 and originally equipped with two turbines. It's located right at the exit of the water tunnel that leads to the high mountain reservoirs built in the 1940s. This water tunnel gives us access to the water reserves of the reservoirs Wasserfallboden and Moserboden. When it starts to get cold in fall, that allows us to turn the power plant into a pumping station at the touch of a button, and the water flows through the water tunnel of the power plant Kaprun Hauptstufe over the pumping station directly to the snow-making devices. By using the large Kaprun reservoirs, constructing reservoirs in the high-alpine terrain of the Kitzsteinhorn could be avoided."
