Included in German energy planning since 2017, the project involves upgrading the voltage from 220 to 380 kilovolts to increase power transmission capacity, particularly for renewables, and to bolster cross-border exchanges.

Starting in 2027, SPIE will manage the implementation of this approximately 18-kilometer project, which includes the installation of 51 pylons, cable replacement, and the decommissioning of 55 existing structures. Temporary lines will be deployed to ensure continuity of supply throughout the construction phase.
