The Active Power Feeder, developed by Primetals Technologies, is now operational at BGH Edelstahl's electric arc furnace in Siegen, Germany, following successful melting tests. This solution utilizes a medium-voltage modular multilevel converter to enhance energy efficiency and reduce flicker compared to traditional methods.

The system, installed 200 meters from the furnace, is designed for easy integration into both existing and new EAFs. Two converters are part of the solution, with the second installed in December 2025 and expected to operate in parallel by mid-2026. BGH aims to reduce its Scope 1 and 2 CO₂ emissions by 42% by 2030.
