German utility RWE and steelmaker Salzgitter have agreed on a significant long-term green electricity supply contract to support Salzgitter’s goal of meeting its power needs with renewables by 2030.
Under the agreement, RWE Supply & Trading will deliver 64 gigawatt hours (GWh) of power from the Boitzenburger Land solar park in Brandenburg for seven years starting in 2027.
This deal supports Salzgitter’s SALCOS program, which aims to cut carbon dioxide emissions in steel production by transitioning to green hydrogen beginning in 2026.

“We are getting serious about green energy sources,” said Marco Hauer, head of energy procurement at Salzgitter Flachstahl. “By 2025, half of our electricity requirements will come from non-fossil sources, and by 2030 we want to be using 100% green electricity.”
Salzgitter’s SALCOS program aims to cut carbon dioxide emissions in its flat-steel business, the company’s largest unit, by adopting low-carbon technologies. Starting in 2026, SALCOS will replace the conventional blast furnace method, which relies on coal, with direct reduction (DR) using green hydrogen produced from renewable electricity.
Additionally, the program will incorporate electric arc furnaces (EAFs) that utilize steel scrap, significantly reducing the climate impact of steel production.
