Uniper SE and TenneT BV will develop a new central network node in Großkrotzenburg, Germany, to address data center-driven power demand in the Frankfurt area, with operations expected to start by 2030. Uniper will sell part of a Staudinger power plant plot to TenneT for a new 380-kilovolt switchyard, enhancing capacity for customer connections in the Rhine-Main area.

The project will strengthen electricity transmission to Frankfurt and neighboring regions, support Uniper's transformation projects, and facilitate the connection of a hydrogen-ready gas turbine plant. In September 2025, TenneT submitted plans for a 380 kV overhead line between Bommersheim and Eschborn to replace an existing line, aiming to increase transmission capacity by over 50%. Additional plans include building another extra-high-voltage line by early 2026.
