Hydro One: Proposed Sudbury Barrie Transmission Line Open House
Join Hydro One at a community open house to learn more about this project. Ontario’s long-term demand for electricity is increasing. To meet this demand, Hydro One will invest in a new priority transmission line between Sudbury and Barrie.
The proposed priority project is a new single-circuit, 500-kilovolt (kV) transmission line that will span approximately 300 kilometres from the Hanmer Transformer Station (TS) in Sudbury to the Essa TS near Barrie, including associated station facility expansions. The line is expected to be in service in 2032.
The project includes the direction from the Ontario government to complete development work for a second new single-circuit, 500-kV transmission line. The proposed transmission line will be developed in partnership with First Nations and help support new generation opportunities in northern Ontario, strengthen reliability and prepare the system for future growth. A recommended in-service date for the second line will be determined by the Independent Electricity System Operator.
This critical infrastructure will support reliability, foster economic growth and investments and ensure a dependable power supply for the significant increase in electricity use anticipated in northern Ontario.
Next steps
Join Hydro One in person or online in April to learn more about the project.
This project will be subject to the Class Environmental Assessment.
(Class EA) for Transmission Facilities (2024), a planning process that includes opportunities for public and community input. Later this year, Hydro One will issue a Notice of Commencement to formally start the Class EA. At that time, Hydro One will also invite you to a second round of community open houses where they will share a project update, including route alternatives for the proposed lines.
If you’d like to be added to the project contact list, share comments or ask questions, please reach out to Hydro One anytime.
