Hydro One Proposes $430 Million Durham Kawartha Power Line

Hydro One has officially requested permission from the Ontario Energy Board to construct a 55-kilometre transmission link between Clarington and Peterborough. The $430 million project aims to bolster grid reliability across eastern Ontario, with a projected completion date set for 2029 to meet rising electricity demands.

The proposed double-circuit, 230-kilovolt line will connect the Clarington Transformer Station to the Dobbin Transformer Station. Beyond physical infrastructure, the project features a significant partnership model, granting proximate First Nations the opportunity to acquire a 50 per cent equity stake in the transmission line. Hydro One and its Indigenous partners intend to collaborate throughout the planning and development phases.

Ryan Docherty, Executive Vice President of Capital Portfolio Delivery, emphasized that the investment addresses aging infrastructure and severe weather vulnerabilities. The application, filed under Section 92 of the Ontario Energy Board Act, provides provincial regulators with the technical design, route mapping, and financial framework required for approval. Once operational, the line is expected to support regional growth in Peterborough, Quinte West, and the Ottawa area.
