"East Bavarian ring"

About the project

The east Bavarian ring is an existing power line route extending roughly 185 kilometres from Redwitz in Upper Franconia through Mechlenreuth and Etzenricht to Schwandorf in the Upper Palatinate. Due to the increasing quantity of renewable energy being fed into the grid, the east Bavarian ring regularly reaches its capacity limits. In order to ensure the continued security of supply and the reliability of the grid as well as to prevent grid failures for the entire region of Upper Franconia and the Upper Palatinate, the transport capacities of the east Bavarian ring must be significantly improved. A new replacement for the east Bavarian ring was therefore included as measure number 18 in the Federal Requirements Plan. Thanks to the passing of the Federal Requirements Plan Act 2013, the urgent necessity of the project for the energy market has been declared by statute. A newly erected replacement along the existing route is planned here in order to upgrade the existing 380/220 kV systems to two 380 kV systems. The existing route will be dismantled after completion of the new systems.
