The Challenge
ArcelorMittal, the world's largest steel producer, was facing issues with its aging electrical installation at its Train 2 facility in Belval, Luxembourg. The company was looking for solutions to reduce downtime risks, improve safety, and enable energy monitoring. It also wanted to modernize its MV power network in line with its sustainability commitments. The project included retrofitting unused but outdated MV switchgear and disposal of old parts in compliance with environmental regulations.
About The Customer
ArcelorMittal is the largest steel producer in the world. At its Train 2 facility in Belval, Luxembourg, the company manufactures sheet piles, a component used for construction of tunnels and seaports, and in preventing rising water in cities like Venice. The Belval site has been in service manufacturing steel for over 100-years. It recently started facing issues related to an aging electrical installation. ArcelorMittal was therefore looking for solutions to reduce downtime risks, improve safety, and enable energy monitoring.
The Solution
Schneider Electric performed a Modernization Performance Safety (MPS) audit on the equipment at the Belval facility. This included an assessment of the current MV network, an evaluation of switchgear and a budget estimation. The audit determined which parts had to be replaced and how to upgrade switchgear to the latest technologies. Schneider Electric retrofitted 13 devices for the new MV network, adding temperature and hygrometry sensors for condition monitoring. Five oil transformers were also selected for modernization. ArcelorMittal wanted to replace them with dry-type transformers which have a lower environmental impact. The Schneider Electric team helped dispose of the oil and other parts in compliance with environmental regulations.
Operational Impact
  • By adopting a circular economy approach for the modernization project, ArcelorMittal managed to save between 15 and 20 percent on the total cost while also meeting sustainability goals.
  • The modernization of switchgear and transformers helped avoid the emission of 170 equivalent metric tons of CO2 and prevented reprocessing of 26 metric tons of materials.
  • With equipment condition now monitored by sensors, the Belval facility staff can track the energy use and identify potential faults before they cause downtime.
Quantitative Benefit
  • 15–20% estimated cost savings on the new installation
  • 5–10% estimated downtime reduction
  • 170 equivalent metric tons of CO2 saved
