Hydro One Networks Inc. has announced it is seeking approval from the Ontario Energy Board (OEB) to build a new transmission line.

The approximately 55-kilometre double-circuit, 230-kilovolt Durham Kawartha Power Line will be built between Clarington Transformer Station (TS) in the Municipality of Clarington, and Dobbin TS in Peterborough County.

The approximately $430 million investment is expected to create jobs during construction and, once complete, will increase the overall transfer capability of the transmission system, support growth and deliver reliable power across Peterborough, Quinte West and into the Ottawa region.

The line is expected to be in service in 2029.

Through Hydro One's First Nation Equity Partnership Model, proximate First Nations will have the opportunity to invest in a 50 percent equity stake in the transmission line component of the project. Together, Hydro One and the First Nations will continue to collaborate on the planning, development and construction of the line.

"Electricity demand is increasing. Aging infrastructure, severe weather and the need to strengthen and secure the grid mean we must make significant investments to support growth and maintain reliability," said Ryan Docherty, Executive Vice President, Capital Portfolio Delivery, Hydro One. "The Durham Kawartha Power Line is part of one of the largest transmission line infrastructure investment portfolios in Canada that we are advancing together with First Nations. We are delivering value for the people of Ontario by building a stronger, more secure and self-reliant system to meet the needs of the future."

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.
