Mandling Storage Power Plant

VERBUND's power plant at Mandling is a storage power plant situated in the municipality of Mandling in Styria. It was constructed from 1983 until 1985 by Steirische Wasserkraft- and Elektrizitäts-AG.

History of the Power Plant 

The plans for the construction of Mandling power plant, which commenced in 1982, provided for an annual storage reservoir at the intersection of Kalte and Warme Mandling, a works water channel and pressure tunnel as well as a power house to east of the town of Mandling. The originally planned annual storage reservoir could not be realised for geological reasons and, for this reason, a smaller brook impoundment at the start of the 2 km long works water tunnel was planned as an alternative. Work commenced at the end of April 1983. The impoundment and the 680 metre pressure pipeline were completed in 1984. The construction work for the power house and the weir system was carried out in 1984. The pipelines were also installed during this construction phase. The weir was closed for the first time in 1985 and damming commenced. The first trial operations took place in 1985 after the filling of the works water channel and the pressure tunnel. Shortly afterwards, the plant was officially commissioned.
