Tange power plant and hydroelectric power

During the years more than 150 water mills have been working along  the River Gudenaa. (River of God) Most of these have disappeared, but the largest of them all – Tange power plant – is still working every day producing renewable electricity which does not pollute the air with CO2.
Tange power plant is the finest and most well preserved industrial power plant in Denmark.

At the Energy Museum you can overlook the engine hall with the three eighty year old generators. You can also visit the exhibition on water power, and you may walk on top of the 800 meter dam, that dams up the water form the river forming Lake Tange, the largest artificial lake in Denmark.

Tange power plant (Also named Gudenaacentralen)

Tange power plant is the largest hydro electric power plant in Denmark producing electricity since 1921. The Plant was build after the 1st World War based on a project designed by the engineers Kristian Thomsen and S. A. Angelo in 1909.

The power plant produces around 11 million. KWh. ´During the 1920’es it covered ¼ of the total consumption of electricity in Jutland. Today it covers the consumption of around 2.500 Danish households, about ½ per cent pr. thousand. Hydro electric power is renewable energy which is environmentally desirable and it does not produce CO2.

Each year the Tange power plant exempts the atmosphere for the burning of 2.280 tons of coal and thus 5.900 tons of CO2.

The buildings of the power plant including the original villas for the employees was designed by the architect from Viborg, Søren Vig-Nielsen, a student of the royal housing inspector Hack Kampmann (known from Theatre of Århus, Marselisborg Castle). The buildings are solid and well proportioned with bases of granite, red bricks, red tiles and details of sandstone. The tallest part of the power plant which originally contained 3 large transformers now provides roof for a modern high tension technology and 3 galleries of exhibition.

Exhibition “Power of the water”

In the exhibition you can explore how the Tange power plant works. You can learn about the development of water mills in the systems of rivers connected to the Gudenaa, and you may set different types of water turbines into working. An old small turbine and a generator used in Denmark are also shown.

Discover the rich wildlife of birds, fish and animals in the surrounding nature.

The Dam and Lake Tange

When the Tange power plant was planned there was no lake at Tange. In order to establish a reservoir of water that enabled the power plant to produce electricity all year round it became necessary to create a large artificial lake. 625 hectares between Kongensbro (The Kings bridge) and the village of Tange were over flooded. 27 farms and houses were torn down to make room for the lake. 192 landowners were influenced by the expropriations of the land for the lake. A dam of 800 meters dams up the water in the river valley, and a 300 meter dug canal leads the water from the lake to the power plant. At the power plant is a fall of 8 to 10 metres letting the water through 3 large double Francis turbines. The turbine turns 214 times pr minute, and each turbine pulls a 1.100 kW generator.
