The Ostbayernring (East Bavarian Ring) is an existing power line operated by the Dutch-German transmission system operator (TSO) TenneT, that stretches about 185km from the Upper Franconian town of Redwitz via Mechlenreuth and Etzenricht to Schwandorf in the Upper Palatinate. After the shutdown of Northeast Bavarian nuclear and conventional power plants, the Ostbayernring primarily transports renewable energies. On several days of the year, more energy is generated by wind turbines and photovoltaic plants in the regions along the East Bavarian Ring than is needed locally. Due to the resulting increase in the amount of renewable energy fed into the grid, the East Bavarian Ring regularly reaches its capacity limits.
To ensure the security of supply and the reliability of the grid and to prevent grid failures for the entire region of Upper Franconia and Upper Palatinate, the transmission capacities of the East Bavarian Ring need to be significantly improved. A replacement construction for the East Bavarian Ring was therefore included in the German Federal Requirements Plan and the urgency of the project for the energy market was legally determined. The new line is being constructed along the existing route, extending the current 380/220kV systems to two 380kV systems.
In the course of the construction of the new East Bavarian Ring and the related grid reinforcement, the Redwitz, Mechlenreuth, Etzenricht and Schwandorf substations of the TSCNET shareholder are also being upgraded. Now the first pylon of the new Ostbayerring has been erected on the site of the Etzenricht substation. TenneT has captured the construction on film in order to give a well-founded impression of the erection process.
