In Germany alone Uniper has an output capacity of almost 2,000 megawatts, primarily on the Lech, Isar, Main and Danube rivers, and is a significant producer of renewable electricity from hydropower. On those four rivers Uniper operates 99 run-of-river hydroelectricity plants. There are also five storage and five pumped-storage hydroelectricity plants.
Combined, these power plants generate around five billion kilowatt hours annually – an amount of electricity that is sufficient to cover the annual needs of over 1.6 million private households and avoid emissions of around 2.8 million tons of CO2 per year. The needs-based coordination of the power plants is controlled from a central control room at the company headquarters in Landshut.
Our hydropower plants in Germany are organised into five power plant groups:
