SPIE is working for long-time customer Amprion to modernise two critical sections of Germany’s electricity grid—ensuring safe, uninterrupted power and enabling greater integration of renewable energy.
SPIE is delivering two major grid upgrades for transmission operator Amprion: a 20.3-km 380 kV line between Osterath and Gohrpunkt and two sections of 380 kV line between Metternich and Niederstedem. Both projects are central to Germany’s energy transition, helping route large volumes of renewable energy across the country’s north-south corridor.
SPIE’s role spans planning, infrastructure development, foundation work, pylon installation and cable mounting. To avoid outages during the Gohrpunkt project, SPIE engineered high-capacity bypasses to maintain supply. Throughout both projects, SPIE’s precision, adaptability and deep partnership with Amprion have been key to maintaining safe, uninterrupted operations while delivering long-term improvements to efficiency, load capacity and grid sustainability.
“ (SPIE’s) entire team is characterised by excellent expertise and particular precision in implementation… The flexibility with which everyone here repeatedly acted, especially at the beginning of the conversions, deserves special mention.”
