VERBUND's power plant at Schwarzach is a storage power plant and situated in the municipality in Schwarzach in Salzburg. It was constructed from 1954 until 1960.

The Schwarzach, Wallnerau-Salzach and Wallnerau-Unterwasser power plants form a unique combination of three power plants in the tightest of spaces and are, as it were, the lower stage of the Kaprun storage power plants. In total, the three Kaplan turbines generate 540 GWh of electricity annually entirely from hydropower.

The Schwarzach power plant is a medium-pressure, diversion-type power plant with a daily storage facility. It uses the gradient of the Salzach between the Högmoos weir system at Taxenbach and Schwarzach and consists of a three-field weir system, the approx. 17 km-long concrete lined headrace tunnel, the Brandstatt compensation basin and an approx. 0.9 km-long reinforced pressure shaft as well as the Schwarzach powerhouse with the 110 kV open-air switchgear.

Högmoos weir system: The Högmoos weir system consists of three weir fields which are closed by a segment gate with flap. The water flows from the inlet structure along the 17 km-long concrete-lined headrace tunnel to the powerhouse.

Brandstatt compensation pond: This daily storage facility with a capacity of approx. 1.8 million m³ enables extensive adjustment of the power plant’s operation to daily peak requirements.
