GE Vernova, SMS group to support energy transformation at SSAB’s Oxelösund steel plant
This contract will oversee the supply of a modular multilevel converter (MMC)-based direct feed system to power a 280 MVA electric arc furnace (EAF) developed for SSAB’s steel plant as part of it’s fossil-free steelmaking commitment.

GE Vernova announced it has secured an order from SMS group to supply a modular multilevel converter (MMC)-based direct feed system for SSAB’s 280 MVA electric arc furnace (EAF). The EAF will equip SSAB’s new melt shop in Oxelösund, Sweden.
This contract, which was booked in June 2024, supports SSAB’s stated commitment to delivering fossil-free steel by 2030. The EAF, supported by GE Vernova’s Power Conversion business, is designed to offer enhanced efficiency, a longer lifecycle, and reduced maintenance costs. The advanced technology is expected to help SSAB transition its steel mill to more sustainable operations.
Blast furnaces, which rely on iron ore and coke as raw materials, emit about 2.32 metric tons of CO2 per metric ton of steel produced. In contrast, the EAF can use up to 100% scrap steel as raw material, reducing emissions to 0.67 metric tons of CO2 per metric ton of steel. This change can represent a significant reduction in carbon emissions.
Meeting stringent grid requirements
EAFs require a high amount of electrical energy and can hence disrupt the power grid. GE Vernova’s MMC-based direct feed system uses advanced injection-enhanced gate transistor (IEGT) technology, designed specifically for EAFs, which seeks to ensure that the new electric furnace (EAF) operates smoothly and efficiently without disrupting the grid. This system uses advanced technology to maintain high power quality and reliability.
“Our power system was chosen because it helps the Oxelösund plant meet their strict electricity quality standards," said Ed Torres, Business Leader, GE Vernova’s Power Conversion business. "By using our system, the plant is expected to reduce electrical disturbances and operate more efficiently. This is a crucial step towards making steel production more sustainable and reducing carbon emissions in the industry.”
“The system includes two parallel converter lines installed at 300 and 400 meters from the EAF, directly connecting to the 34 kV bus. This setup mitigates flicker, maintains very low harmonics, and ensures a unified power factor,” he added.
The delivery and installation of the equipment are scheduled for the first half of 2026, with the EAF first heat scheduled for the fourth quarter of 2026.
