With the commissioning of the battery research factory, the electricity demand at Hansa-BusinessPark will rise to up to 23 megawatts. To meet this demand, a new substation with a powerful 110 kV connection to the Münster electricity grid is being built. The plan is to lay a new power line approximately six kilometres long. The consortium is responsible for constructing the line, which will mainly be built using the open construction method as a travelling construction site in around 100 sections with lengths between 50 and 200 metres.

Protective pipe laying with HDD and press drilling

The construction method will be predominantly open with shoring boxes, while closed methods such as HDD and press drilling will be used for railway and water crossings. There will be six HDD drillings as well as one press drilling under the DB route. The socket pits will be constructed after completion of the empty pipe route. These pits will be used for the subsequent installation of the power cables. The Kappenberger Damm was widened in November 2024 to avoid a complete closure during the main construction phase.

Precision despite limited space

The work is being carried out under flowing traffic on short construction sections with limited space. Intersecting lines, varying soil conditions and a high groundwater level pose particular challenges.

The first construction phase was successfully completed at the end of October, and work is currently underway on the second phase. With this project, PORR transport route engineering is making an important contribution to the energy transition and to ensuring a sustainable infrastructure for Münster as a centre of innovation.
