The Ontario Energy Board has given the go-ahead for PUC Transmission to build a new 230 kV transformer line and transformer station that will service Sault Ste. Marie’s west end.

The new infrastructure will also play a critical role in supporting Algoma Steel’s transition from coal to electric arc furnaces in its steel-making process.

"We are thrilled to receive this approval from the Ontario Energy Board," said Rob Brewer, President & CEO, PUC Transmission LP. "This project is a critical step in ensuring a resilient and sustainable energy future for our region. Our partnership with Algoma Steel will result in significantly reduced carbon emissions as well as bolster our community’s economy for decades to come.”

The new line and station will significantly improve system reliability to accommodate new loads in Sault Ste. Marie’s west end and the surrounding area, including the new load of approximately 280MW for the two new electric arc furnaces at Algoma Steel.

Algoma’s planned new state-of-the-art electric furnaces are expected to reduce carbon emissions by 70%, which is the equivalent of taking one million cars off the road.

“This milestone marks a significant advancement in enhancing Sault Ste. Marie’s power infrastructure, which is vital for supporting sustainable economic growth and our transformation to electric arc steelmaking—a key part of our commitment to environmental sustainability,” said Algoma President and CEO Michael Garcia.

The PUC project has undergone rigorous environmental and technical assessments to ensure it meets all regulatory requirements and aligns with community interests.

Construction of the line is expected to start in 2025 with anticipated completion by 2027.
