Wind Energy – Steel Supply
Salzgitter from Germany 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.
These wind towers are the so-called ‘Siemens Gamesa GreenerTower’.
The special feature of this tower is its CO2eq emissions of less than 700 kg per tonne of steel. This is a significant step for the industry, as the production of wind towers alone is responsible for more than two thirds of all CO2eq emissions from wind turbines.
The new CO2eq-reduced tower has been part of Siemens Gamesa’s product portfolio since 2024 and can be used as an option for all future onshore and offshore wind turbines.
The first use of the Siemens Gamesa GreenerTower is now the offshore wind farm Thor in the Danish North Sea on the west coast of Jutland, which is planned to be completed by the end of 2027 and has a planned capacity of more than 1,000 MW.
This will make Thor Denmark’s largest offshore wind farm to date with a total of 72 wind towers, which will supply more than one million Danish households.
