With Energy into the future

About the project

The energy transition which Germany has decided on is being implemented at all levels. With its amendment of the "Combined Heat and Power Act" (German: KWK-Gesetz) and the "Federal Requirements Plan Act" (German: BBPIG) at the end of 2015, the Federal Government has taken important steps to ensure the success of the energy transition in Germany. A rapid and needs-based upgrading of the power grids which is widely accepted by the population is necessary to achieve these ambitious objectives together. In this case the SuedOstLink will play an important role in securing the power supplies to southern Germany over the coming decades. 

The direct current link from Sachsen-Anhalt to Bavaria is a joint project between TenneT and 50Hertz.
