The Vianden pumped storage plant in Luxembourg has a nominal output of 1290 MW in turbine mode and 1040 MW in pump mode. It was built from 1954 to 1964 and dates back to plans from 1925. The industrial plant was officially opened on April 17, 1964 by Grand Duchess Charlotte of Luxembourg . The plant consists of a reservoir on the Our , two upper basins at a height of 509 m, an underground cavern hall and a system of pressure pipes. It is used to store water to generate electrical energy.
The working capacity of the turbines is 4,630 MWh per cycle (pumps 6,240 MWh).
technical description
The principle of the pumped storage plant is to be able to produce additional electrical energy during peak consumption . The water flows through eleven turbines that use generators to produce electrical energy. In times of low consumption, the water is pumped up in the opposite direction from the lower basin into the upper storage tank, so that it is available for generating electrical energy at peak times.
Machines 1 to 9
In the large machine hall there are nine of the eleven machine groups, which in addition to the turbine include a generator and a pump. The turbines each generate an output of 100 MW. The nine pumps have a slightly lower output than the turbines, a total of 621 MW.
Machine 10
The tenth machine was built in a side valley in 1970. It has a pressure shaft 4.50 m in diameter, which is 1375 m long to the upper basin. In contrast to the other nine turbines, it has a vertical axis. The nominal output of the tenth machine is 196 MW in turbine and 220 MW in pump operation.
Machine 11
Work on the eleventh machine, which has been planned since 2006, began in early 2010. The eleventh machine has a nominal output of 195 MW in turbine operation and 189 MW in pump operation. For this, the storage spaces in the upper and lower basins had to be enlarged. The contract was awarded at the end of 2009 and construction was initially scheduled to be completed in autumn 2013. On November 4, 2014, the eleventh turbine was officially put into operation in the presence of the Grand Duke of Luxembourg Henri and the German Federal President Joachim Gauck .
Storage basins and caverns
After the Obersauer Reservoir , the Our Reservoir is the second largest lake in Luxembourg. The lower basin extends from the Ourtalsperre near Vianden to Stolzemburg . It is 8 km long and has 10.80 million cubic meters of storage space.
The upper basin lies on the heights west of the Ourtal. With a capacity of 7.23 million m³, it has a dam that is on average 14 m and a maximum of 35 m high. The usable amount of water is up to 6.84 million m³. The cavern under the Nikolausberg is 330 m long, 25 m high and 15 m wide. The pressure pipes are 6 m and 6.50 m in diameter and 625 m and 856 m long.

Mains connection
The connection to the European network does not take place in Luxembourg, but in Germany at the 220 kV maximum voltage level via the switchgear in Niederstedem and Bauler , which is why the system is also listed in the power plant list of the (German) Federal Network Agency .
Operator and owner
The power plant is operated by Société électrique de l'Our (SEO), in which the German RWE and the State of Luxembourg each hold 40.3%. Other shareholders include the investment company Luxempart (5.44%), the country's largest electricity provider Enovos Luxembourg (4.46%) and the leading Belgian energy service provider Electrabel (3.44%).
RWE Supply & Trading in Essen is responsible for controlling the electricity network.
Others
The Vianden pumped storage plant is depicted on the former Luxembourg 100 franc note from 1963.
The factory can be visited after registration. In a projection room there are films about the power plant as well as about energy generation and consumption in Europe.
