Pipe systems are crucial for rapid grid expansion
Following the German government’s decision to phase out nuclear and coal-fired power generation by 2038, the rapid expansion of the German transmission grid is essential. For efficient expansion, the choice of the right pipe systems and connection technologies is a decisive component for success.
Currently, the share of renewable energies in Germany stands at 46%. This is to be increased to 65% by 2030. In addition to the conversion of energy generation, the transport of electricity to the consumer also poses a challenge. In the future, it will not always be possible to generate electricity close to the point of consumption. A large proportion of future wind energy will be generated in the North and Baltic Seas. In order to reconcile increasing energy demand with climate targets and to ensure security of supply, strong power grids designed for renewable energies are required. According to the 2019–2030 Electricity Grid Development Plan, the Federal Network Agency intends to build an additional 3,600 kilometers of transmission lines by 2030. Part of the solution is expansion using High-Voltage Direct Current (HVDC) transmission. The expansion plan includes three DC corridors intended to transport electricity from the north to the south: Südlink, Südostlink, A-Nord (Ultranet), and a planned fourth corridor. The corridor for the fourth DC line is planned to run from Heide in Schleswig-Holstein via Wilhelmshaven to Polsum in North Rhine-Westphalia.

The tight schedule for the expansion of the DC corridors presents transmission system operators and the responsible construction companies with major challenges. The success of grid expansion projects depends on the fast and uncomplicated completion of the underground cable routes. To ensure rapid and safe construction progress for the individual route sections, the use of high-performance pipe systems is required. This allows specific sections to be piped and closed independently of the cable pull-in.
