Award of decarbonization services contract for a major ArcelorMittal steel production plant in France

• A world leader in steel, ArcelorMittal has awarded a consortium comprising Técnicas Reunidas and Idom the services for the engineering, procurement, and construction management contract (EPCm) for a facility that will contribute to the transformation and decarbonization of the large steelmaking site ArcelorMittal operates in this northern French city.
• A 2-million ton electric arc furnace (EAF) and a ladle furnace (LF) will be built. They will produce steel with three times less CO2 than through the blast furnace route.
• This contract builds on prior work by Técnicas Reunidas in consortium with Idom, which provided consultancy and engineering services in earlier project phases. 
• Through its participation in this project, Técnicas Reunidas reinforces its contribution to the European Union’s heavy industry decarbonization strategy and its entry into the low carbon steel market.

A 50/50 consortium between the Spanish companies Técnicas Reunidas and Idom has commenced its support to the transformation and decarbonization of the steelmaking site operated by ArcelorMittal in Dunkirk (France), following the award of the contract to build a new Steel Making Plant (SMP) in the site. 

The consortium’s work, under an EPCm contract, will comprise project management, detailed engineering, procurement, construction, commissioning, and testing at the steelmaking plant, including the development of an electric arc furnace (EAF) and a ladle furnace (LF) for secondary refining.

The project also includes the development of auxiliary systems and infrastructure, site preparation, and subcontracting certain studies and services to third parties.

The new facilities will be integrated into the existing steelworks, thus representing a significant transformation of the site’s steel complex and, above all, making a very significant contribution to decarbonization.

The new electric arc furnace route will generate 0.6 tons of CO₂ per ton of steel produced, using a mix of scrap, direct-reduced iron (HBI/DRI), and hot metal, resulting in three times less CO₂ than the blast furnace route. The EAF will have an annual production capacity of 2 million tons of steel. The start of operation of the new facilities is estimated for 2029.

This contract builds on the work previously carried out by Técnicas Reunidas, in a consortium with IDOM, during earlier phases of the project, in which it provided consultancy and engineering services under a FEED (front-end engineering design) contract.

Eduardo San Miguel, CEO of Técnicas Reunidas, has stated that “this contract confirms our company’s role as a key player in the decarbonization of the European steel industry, strengthens our entry into the green steel market, and is fully aligned with two of the main pillars of our SALTA Strategic Plan: the promotion of service contracts and the development of decarbonization activities. I want to thank ArcelorMittal warmly for their trust in our consortium. We are eager to get to work”.
