We Know no National Borders When We Think of Hydroelectric Power
We operate more than 200 hydro power plants in Sweden, Germany, Italy and Spain from which some are introduced below.
On the Ångerman
The river Ångerman is one of the most important rivers for hydroelectric power in Sweden. There is a cascade of plants including four E.ON owned plants: Hällby, Gulsele, Degerforsen and Edensforsen. All the plants in the cascade are remotely controlled by satellite communication since 2001.
On the Ljungan
Flåsjö plant is located furthest upstream on the river Ljungan. It is an underground station. Hydroelectric power plant Trångfors is located downstream the Flåsjö plant.
On the Danube
Along the Danube E.ON Wasserkraft possesses 14 individual run-of river power generation plants with an installed power rating of 226 MW and an average annual electrical power output of 1,462 GWh. The pumped storage power station Happurg with an installed power rating of 160 MW is ramped in to counteract peak load spikes.
On the Edersee and the Main
Three pumped storage power plants, 37 run-of-river power plants and three reservoir power plants have an aggregate installed power rating of 900 MW. The run-of-river and reservoir power plants feed an annual average output of 840 GW into the supply network.
On the Inn
3 hydroelectric power stations on the Inn provide a controlled generation of 1053 GWh a year with an installed power of 179 MW.
On the Isar
There are 25 run-of-river power plants with an aggregated installed power rating of 240 MW and provides an annual average output of 1,324 GWh. The storage power plant at Lake Walchen has a power rating of 293 GWh, much of which is utilized by the railways.
On the Lech
22 run-of-river power plants and a storage power plant located in Roßhaupten, with an aggregated installed power rating of 258 MW, generate, on average, 1,162 GWh of electricity per year.
Terni Hydroelectric Complex
The Terni Hydroelectric Complex extends over a vast area in the provinces of Terni, Perugia, Rieti and Macerata. It consists of 16 hydroelectric power plants, 3 reservoirs (Salto, Turano and Corbara), and 1 pumping plant. It utilizes the waters of the Nera, Velino and Tiber rivers and their tributaries in central Italy. With an installed capacity of 681 MW, the nucleo generates about 1,3 TWh of zero-carbon electricity per year, able to supply energy to about 500.000 families. A comprehensive technical upgrade program, to be concluded in 2011, will enhance efficiency and extend the operating lives of 26 untis at a total of 11 hydro power plants. The upgrade, which will cost about €190 million, encompasses new turbines, generators, and automated control systems.
The Aguayo-Aguilar plant group
This group comprises the four hydroelectric plants in Aguayo, Torina, Besaya and Aguilar, which are located on the Torina, Besay and Pisuerga rivers in the provinces of Palencia and Cantabria. It has an installed capacity of 389 MW.
The Navia plant group
This group is made up by the Arbon, Doiras and Silvon plants, which are located on the Navia River. It has an installed capacity of 162 MW.
The Picos plant group
This group is composed of five plants: the plants at Cama and Arenas, which are located on the Cares river, the plants at Urdon and La Paraya, located on the Urdon and Aller rivers respectively, and the Remolina Plant, which is located on the Alto Esla, to the north of the province of Leon. The group has a total installed capacity of 117 MW.
