PUC Transmission LP

Quick General Facts About PUC Transmission LP

• PUC Transmission was incorporated early 2021.
• PUC Transmission was approved in October 2021 for a transmission licence by the OEB.
• PUC Transmission will be investing in the order of ~$190 million to construct new transmission facilities that will provide power to Algoma Steel’s new electric-arc furnaces.
• This new power supply to Algoma Steel will result in improved service for Algoma Steel and substantially lower carbon footprint for the community.
• Construction of the facilities is anticipated to start by 2025, with completion anticipated by 2027.
• The 230 kV transmission line will utilize single steel poles with side-post insulators to carry two circuits, each rated at 400MVA.
• The line and station will supply Algoma’s new load of ~300MW.

New Line & Algoma Steel’s Arc Furnaces:

• The new PUC 230 kV transmission line will convey electricity from Hydro One’s Third Line Station in the city’s north end to a new PUC transformer station in the west end, near Algoma Steel.
• The new transmission facilities will support the steel plant and its $700 million project to build and operate two new state-of-the-art electric arc furnaces. Algoma Steel Inc. says its investment will lead to a 70 per cent reduction in carbon emissions.

Transmission Poles:

• The poles will be approximately 40 meters tall and spaced approximately 200 meters apart
• The poles will look like the steel poles currently situated on the south side of Lyons Avenue between Patrick Street and Korah Road, as shown in the picture below.
