As part of the Zemm-Ziller Development, construction on the dam began in 1981 and, along with the Häusling Pumped Storage Power Plant, it was completed in 1986.

[1][2] Water released from the reservoir reaches the Häusling Power Plant 10 km (6 mi) downstream.

The power plant is located at an elevation of 1,060 m (3,478 ft) and contains two 180 MW Francis turbine-generators.

[4] Using its pumped-storage capability, the power-station receives water from the Stillupp Reservoir 8 km (5 mi) to the west in an adjacent valley at 47°07′17″N 11°51′58″E / 47.12139°N 11.86611°E / 47.12139; 11.86611 (Stillupp Dam) and pumps it up to the Zillergründl Reservoir.

The pumping and replenishment of the reservoir occur at night, during low energy demand periods.
