Salzgitter AG to supply steel to Siemens Gamesa for offshore wind farm
Ilsenburger Grobblech GmbH and Siemens Gamesa have signed a contract for the delivery of around 25,000 tonnes of heavy plates for the construction of 36 wind towers.
The special feature of the Siemens Gamesa GreenerTower is its CO2eq emissions of less than 700 kg per tonne of steel. The first use of the Siemens Gamesa GreenerTower is the offshore wind farm Thor in the Danish North Sea on the west coast of Jutland, which should be completed by the end of 2027 and has a planned capacity of more than 1,000 MW.
The heavy plates for the 36 GreenerTowers will be supplied by Ilsenburger Grobblech
GmbH( ILG) and Mannesmann Grobblech GmbH( MGB).“ We are delighted that ILG and MGB are the first certified suppliers to make a significant contribution to reducing the global CO2eq footprint by supplying lowemission heavy plates. To this end, we have invested in new equipment to be able to supply such wind projects with 18 – 24 meter long plates. This includes, for example, the investment in the transport line for finishing with an overhead crane and a mobile roller table extension,” said Oliver Laubner, sales manager at Ilsenburger Grobblech GmbH.
“ The energy transition demands end-to-end value chains working together to
eliminate CO2eq emissions. GreenerTowers exemplifies this collaboration. If all towers installed by the company in one year were replaced with GreenerTowers, it would be equivalent to removing over 466,000 cars from European roads for a year. Innovations like this are crucial to achieving our sustainability goals” stated Maximilian Schnippering, head of sustainability at Siemens Gamesa.
The heavy plates for the wind towers are to be delivered to the wind tower manufacturers Windar in Spain and Welcon in Denmark from March to October 2025.
