SuedLink: possible underground cable corridors released

  • TenneT and TransnetBW plan to transfer entire SuedLink cable network un-derground
  • Citizen involvement starts today, information forums from mid-October
  • SuedLink to transport electricity from renewable energy sources from 2025

The transmission system operators TenneT and TransnetBW have published their proposals for possible underground cable corridors of the SuedLink direct-current connection today. Lex Hartman, Member of the TenneT TSO GmbH management board, clarified: “We are planning SuedLink as a full underground connection – 100 per cent underground power lines. This has been the wish of the citizens for whom politics has paved the way.” Hartman further explained that renowned expert planning offices for environmental and nature protection have identified possible, suitable corridors in the first step of the endeavour. Dr Werner Götz, Member of the TransnetBW GmbH management board, announced that these corridors are now being presented to the public: “We are seeking dialogue with the public even before the official proposal process starts.” The imminent period of citizen involvement will serve as a forum for explaining the plans and discussing the proposals. “We want to inform the public early and transparently. This will help us ensure that all available local and regional information will flow into the planning and optimise it.” Hartman and Götz pointed out that SuedLink is intended to be completed in 2025. They conceded that this was an ambitious schedule. Both of them appeared confident that the plans for the underground power lines allow for gentle solutions on location and, in turn, speedy processes. TenneT and TransnetBW intend to submit their application for federal planning permission to the Federal Network Agency in the first quarter of 2017. 

After the priority of underground cables for direct current connections was legally enshrined at the end of the past year, the two transmission system operators started making plans for SuedLink. The redesign adheres to the current legal and licensing regulations. The new proposals for the underground cable corridors are based on criteria for buried cables, which are fundamentally different from the criteria that govern the planning of overhead lines. The most important planning criteria for direct-current underground power lines include linear, short routes, terrain conditions (mountains, forest) and soil properties. During the planning phase, the grid operators were engaging in a constructive exchange with specialist authorities and other public agencies.

TenneT and TransnetBW will be organising information forums between mid-October and mid-November. More than 30 events will be held in the districts in which the proposed underground cable corridors might be located. They will enable citizens to learn in detail about the planning foundations and the technology used and contribute information about the proposed underground cable corridors. As of now, online participation is also possible: The websites www.tennet.eu and www.transnetbw.de show potential corridor routes and explanations about all topics relating to the planning of SuedLink and the dates of the information events. Information can be contributed directly through an innovative online planning and participation tool.
