Enercon, Ilsenburger Grobblech (a Salzgitter subsidiary), and Schönebecker Maschinenbau (SMB), part of TM Group, are collaborating to produce a lower-emissions steel tower. The components will be used in early 2025 for an E-138 EP3 wind turbine at the Diepholzer Bruch wind farm in Lower Saxony, Germany.
The tower consists of pre-edged steel plates at the base and conical steel sections at the top. To reduce greenhouse gas emissions in heavy plate production, Ilsenburger Grobblech is using CO₂-reduced slabs from its sister company Peiner Träger and another European partner. These slabs are made entirely from scrap in an electric arc furnace (EAF) and benefit from an energy mix with a significant share of renewables.
