EDF’s Subsidiary Dalkia Recovers Secondary Energy from Arcelormittal’s Site to Fuel Dunkirk Urban Network

EDF’s subsidiary Dalkia specializes in supplying high-pressure steam, hot water, compressed air and cogeneration solutions. It also helps
companies to reduce their energy consumption through an array of services ranging from individual assessments to optimization of sourcing and maintenance contracts.

In Dunkirk (North of France), Dalkia recovers the lost energy from ArcelorMittal’s industrial site, and injects it into the city’s district heating network. The 40 km long network heats the city hall, a swimming pool, the university, a shopping mall and thousands of housing units.

There is a two-fold economic and environmental benefit: for ArcelorMittal, a revenue stream from heat as a by-product of industrial processes while reducing its ecological footprint; for the city, stable energy costs for the heating network and a bill reduction of 15-20% compared to oil or gas, and 20,000 tonnes of CO₂ avoided each year.

Thanks to its “Eco-impact” solution, Dalkia helps to create value from previously unexploited energy. By recovering site waste, industrial actors contribute directly to the regional effort towards the energy transition. Waste becomes a new local source of renewable energy, helping to diversify the energy mix in the region.
