According to Primetals Technologies, the compensator will be the largest industrial compensator ever installed at a North American steelmaking plant. 

Primetals Technologies said it has been working Gerdau Petersburg since 2022 on the project. Gerdau has accepted conceptual design of the compensator, and groundbreaking is to take place soon, Primetals Technologies said. Work is to last 27 months. 

“This order demonstrates Gerdau’s confidence in the Primetals Technologies team. Implementing such complex technology requires deep knowledge of AC EAFs and grid-level electrical power systems — expertise that differentiates Primetals Technologies from most electrical power designers,” Primetals Technologies said.
