The Melk power plant is a run-of-river power plant on the Danube in the immediate vicinity of the famous Melk Abbey in the state of Lower Austria . The Österreichische Donaukraftwerke Aktiengesellschaft started it in 1979 and put it into operation in 1982.

technical description

The system was built as a low-rise structure with six weir fields and two locks (each 230 × 24 m). The reservoir length of the river is 22.5 km and the reservoir target is 214  m above sea level. A. at river kilometer 2038.0.

Nine machine sets in the power house, which was built on the right bank of the Danube, supply electricity to the public power grid , supplying around 500,000 households on average.

Each of these sets consists of a Kaplan bulb turbine , each with a directly coupled three-phase generator . The turbines have a nominal output of 22,300  kW each , a nominal flow rate of 300 m³ / s each and an impeller diameter of 6.3 m. The nominal speed is 85.7 per minute. Starting in 2016, seven of the turbines will be gradually replaced with newer models, one annually while the power plant is in operation.

ecology

In order to impair the landscape as little as possible, the electricity generated is not transported to the high-voltage network via overhead lines , but via underground cables in the dike on the right bank.

A bird pond was created and a gravel island was raised in the AltLauarm , which is a valuable retreat for water birds. A new relaxation area was created around the oxbow lake as a leisure paradise.
