Hydro One Networks has filed an application with the Ontario Energy Board (OEB) to build the Welland Thorold Power Line.

The project plan calls for the construction of a double-circuit, 230-kilovolt transmission line between Abitibi Consolidated Junction, within an existing Hydro One transmission corridor in Thorold and Crowland Transformer Station (TS) in Welland.

The scope of work also calls for the expansion of the Crowland TS.

The approximately $311-million investment in the region is expected to start in 2027 and be complete by 2029.

Through Hydro One's First Nation 50-50 Equity Partnership Model, area First Nations will have the opportunity to invest in a 50 percent equity stake in the transmission line component of the project.

"Ontario is facing historic growth demand for electricity in the next 25 years, especially in the southwest," said Sonny Karunakaran, Vice President, Strategic Projects and Partnerships. "Electricity is the foundation that will help connect and power new homes, businesses and industries. Hydro One's success is tied to Ontario's success and the time to invest and partner with First Nations is now, so we have a system that meets the needs of the future."

Filing a leave to construct application under Section 92 of the Ontario Energy Board Act, 1998 is a requirement for Ontario electricity transmitters to obtain approval from the OEB to construct, expand or reinforce the electricity transmission system or interconnections.

Hydro One’s application provides the details of the project including timing, route, design and cost.
