Sault Ste. Marie, ON, June 11, 2019 – Today, Hydro One announced plans to invest approximately $40 million in significant infrastructure upgrades to improve service reliability and support future economic growth in the Sault Ste. Marie region.

Over the next four years, Hydro One plans to improve its high-voltage electricity transmission service and ensure public safety in the Sault Ste. Marie area by replacing approximately 70 kilometres of transmission line and wood poles, upgrading two transmission stations and conducting tree trimming along nearly 400 kilometres of Hydro One corridors.

“A loss of power grinds life to a halt, impacting businesses, families and productivity. By investing in the Sault Ste. Marie region, Hydro One plans to minimize power outages and keep the public safe,” said Mark Poweska, President and Chief Executive Officer, Hydro One. “A strong and reliable high-voltage system helps to grow the economy by helping businesses start up and grow. Through the replacement of aging infrastructure in the region and across the province, Hydro One will be able to build a stronger, safer and more reliable electricity system for Ontario now and into the future.”

These projects are expected to include:

• Upgrading the Sault#3 transmission line, which was put in service in 1929 and spans from Sault Ste. Marie to the Montreal River Area.
• Upgrading the D.A. Watson and Echo River Transmission Stations.
• Tree trimming along 400 kilometers of Hydro One corridors.

In October 2016, Hydro One acquired Great Lakes Power Transmission LP and streamlined the operations of both organizations in the region, maintaining a work centre with staff accountable for the maintenance and replacement of local infrastructure. Now known as Hydro One Sault Ste. Marie, it operates as a standalone licensed transmitter and connects Northern Ontario to Southern Ontario. It is the second-largest electricity transmitter in the province.
