Hölscher Wasserbau’s key role in Germany’s energy transition

Germany is currently implementing numerous infrastructure projects as part of its energy transition to efficiently distribute renewable energy across the country. Key projects include the BalWin1 and BalWin2 high-voltage direct current (HVDC) lines, which connect offshore wind farms in the North Sea to the onshore transmission network. These projects are crucial for replacing conventional power plants and transporting wind power to grid connection points.

Hölscher Wasserbau is responsible for groundwater management in these projects, which is essential for the underground installation of the cables. By lowering the groundwater level, the soil remains dry and stable during construction. The extracted groundwater is treated and then returned to the natural environment in an environmentally friendly manner. Additionally, Hölscher Wasserbau manages the groundwater for the A-Nord HVDC project, which will transport two gigawatts of wind energy from the north to consumption centres in the west and south. This ensures the safe underground installation of the cable.

Hölscher Wasserbau brings extensive experience and innovative technologies to these projects, ensuring that groundwater management is sustainable and environmentally friendly. The company plays a significant role in the implementation of Germany’s energy transition and supports the goal of a sustainable energy supply. These projects highlight Hölscher Wasserbau’s importance as a partner in the realisation of new energy infrastructure.
