This investment will support economic growth in the Ottawa area

TORONTO , May 29, 2026 /PRNewswire/ - Today, Hydro One Networks Inc. (Hydro One) announced it has filed a leave-to-construct application with the Ontario Energy Board (OEB) to seek approval to build the Orléans Area Reinforcement Project.

The Orléans Area Reinforcement Project includes the construction of a new 11-kilometre 115-kilovolt (kV) transmission line within an existing transmission corridor between Hawthorne Transformer Station (TS) and Orléans TS, located in the Greater Ottawa Area. The project also includes converting an existing 115-kV transmission line between the two stations to 230-kV. The approximately $100 million investment in the region is expected to bolster capacity, improve the system's regional transfer capability and strengthen reliability. The project is expected to be in service by 2029.

"Ontario's electricity demand is increasing, and we must continue to invest in the system to meet this demand and support growth," said Ryan Docherty, Executive Vice President, Capital Portfolio Delivery, Hydro One. "This project will support a reliable supply of power to Canada's capital, strengthen reliability and create a stronger and more secure system to meet the needs of the region and province."

Filing a leave-to-construct application under Section 92 of the Ontario Energy Board Act, 1998 is required for electricity transmitters in Ontario to obtain approval from the OEB to construct, expand or reinforce the transmission system. The application includes details on the project's route, design, timing and cost.
