SSAB to install one of the world’s most powerful Electric Arc Furnaces

SSAB is taking a significant step toward fossil-free manufacturing with the construction of a 190-ton electric arc furnace (EAF) at its Oxelösund steel plant in Sweden. Developed by SMS group, the EAF will be one of the largest of its kind globally, with an upper shell diameter of 9.3 meters. Scheduled for commissioning in late 2026, the furnace is designed to support SSAB’s transition away from fossil fuels while contributing to a three percent reduction in Sweden’s total CO2 emissions.

Advanced grid integration technology

To ensure smooth operation within the constraints of Sweden’s power grid, the project incorporates a modular multilevel converter (MMC)-based direct feed system provided by GE Vernova. This advanced technology addresses key power quality challenges, such as reducing flicker and harmonic distortion while maintaining a stable power factor.

Andrea Lanari, Vice-President Metallurgy Steelmaking at SMS group, noted, “This project combines SMS’s steelmaking expertise with GE Vernova’s grid technology, providing SSAB with the tools needed to achieve their decarbonization goals.”

The MMC-based system uses injection-enhanced gate transistor (IEGT) technology to deliver reliable power performance. Two converter lines, located 300 and 400 meters from the furnace, will connect directly to the 34 kV bus, ensuring stable grid interaction and compliance with strict electricity quality standards.

Focus on sustainability and efficiency

Jan Heimann, Executive Vice President of SMS group, highlighted the practical benefits of the project: “The integration of advanced control systems will help SSAB maintain high power quality and efficiency while reducing its environmental impact.”

Ed Torres, Business Line Leader & COO of GE Vernova’s Power Conversion business, explained the technical advantages of the system. “This setup is designed to minimize grid disturbances and improve operational efficiency, supporting SSAB’s move toward more sustainable steel production.”
