Hydro One invests $19.2 million to refurbish transmission station

Hydro One Dunnville Station Upgrade enhances Ontario's transmission system through transformer station refurbishment, boosting capacity, grid reliability, and local infrastructure for Haldimand County customers, enabling safe, reliable electricity delivery and future community growth.

Hydro One announced recently the completion of a $19.2 million refurbishment to the Dunnville Transmission Station TS in Haldimand County. The investment includes the building of a new station and installation of new transformers and an additional feeder line. This refurbishment project will ensure there is enough electrical capacity for Haldimand County's needs and to support future growth in the area.

"Investment in our transmission system, including major reliability upgrades in Toronto to support growth, is critical to meet the current and future needs of the communities we serve," said Carm Marcello, President and CEO, Hydro One. "The refurbishment of this transformer station, like the Chesterville transformer upgrade project, provides improved local infrastructure and capacity for the community to grow while ensuring Hydro One can continue to deliver safe and reliable electricity."

The Dunnville Transmission Station was built in 1952 and has served customers in Haldimand County for more than 60 years. The project began in April 2014 and was completed ahead of schedule. It involved the complete removal of the original station and construction of a new transformer station on the site and took approximately 25,000 construction hours to complete.

Hydro One delivers electricity safely, reliably and responsibly to homes and businesses across the province of Ontario and owns and operates Ontario's 29,000 km high-voltage transmission network, including the Ontario-Michigan interconnection corridor, that delivers electricity to large industrial customers and municipal utilities, as well as the Canadian-U.S. interconnection circuit replacement initiative, and a 123,000 km low-voltage distribution system that serves about 1.3 million end-use customers and smaller municipal utilities in the province. Hydro One is wholly owned by the Province of Ontario.
