SuedLink: Regional planning offices take up work

10.06.2020

With around 700 kilometres of underground cables to be laid and around €10b to be invested, the SuedLink 525kV line is the largest and probably the most important individual project of the energy transition in Germany. By connecting the windy regions of northern Germany with the consumption centres in the industrially highly developed south and west, “power highways” such as SuedLink are indispensable for achieving Germany’s and Europe’s climate goals. SuedLink is realised jointly by the two TSCNET shareholders TenneT, the Dutch-German transmission system operator (TSO), and TransnetBW, the TSO from southwest Germany.

SuedLink has just taken the next big step: After the Federal Network Agency (Bundesnetzagentur) initiated the plan approval procedure for the first sections in February 2020, the two TSOs have now awarded the contracts for the regional planning offices, which are responsible for the detailed planning of the underground DC connection. These offices, some of which have already been involved in the previous SuedLink planning, take care of all operational tasks – initially in the context of the approval procedure, and later also in the supervision of construction. This includes, among other things, route mapping, construction logistics, environmental planning, and awarding of contracts for civil engineering work. On special topics such as soil investigations, they cooperate with local companies.

The overall project was divided into nine planning sections for the award of contracts. After an extensive bidding competition, a total of four companies were awarded the contract for the three northern sections under the responsibility of TenneT and the six southern sections under the responsibility of TransnetBW. TenneT Managing Director Tim Meyerjürgens explains: “The offices are now preparing the detailed planning for the routing and are taking a very close look at the conditions on site.” This will help the TSOs to accurately develop appropriate routing proposals. Dr. Werner Götz, Chairman of the TransnetBW Executive Board, adds that, due to their local presence, the offices can optimally consider the regional conditions for the detailed planning. “They are intended to discuss the proposals together with the project developers in a close dialogue with the owners and land managers concerned and to review their advice when preparing the approval documents.”
