Hydro One's Ambitious Plans for Power Transmission

Hydro One Networks Inc., Ontario's leading electricity transmission and distribution provider, has announced plans to enhance the province's electricity infrastructure significantly. On May 19, 2026, the company formally submitted applications to seek approval from the Ontario Energy Board (OEB) for two critical projects: the Northeast Power Line and the Longwood to Lakeshore Transmission Line. These initiatives are poised to not only reinforce the electrical grid but also stimulate local economies and support various industries across Ontario.

Project Overview

Northeast Power Line

The Northeast Power Line is set to become a pivotal single-circuit, 500-kilovolt (kV) transmission line connecting the Hanmer Transformer Station in Greater Sudbury to the Mississagi Transformer Station near Wharncliffe. This infrastructure is integral to meeting the increasing electricity demand across Ontario. The project, with a budget of approximately $1.8 billion, is expected to bolster the transmission system’s capacity between northeast and northwest Ontario by an impressive 900 megawatts (MW). Its completion is projected for 2029, marking a significant step towards enhancing energy reliability in the region.

Longwood to Lakeshore Transmission Line

Simultaneously, the Longwood to Lakeshore Transmission Line, costing around $1.2 billion, will link the Longwood TS in Strathroy-Caradoc to the Lakeshore TS. This single-circuit, 500-kV line aims to deliver around 550 MW of power to southwest Ontario, thereby supporting local jobs and benefitting the agri-business and manufacturing sectors. The anticipated completion year for this project is 2030.

Collaboration with Indigenous Communities

A noteworthy aspect of these projects is Hydro One's commitment to partnering with Indigenous communities through its First Nation Equity Partnership Model. This innovative approach allows near Indigenous communities to acquire a 50% equity stake in the transmission line segments for both undertakings. Hydro One’s initiative seeks to foster collaboration in the planning, development, and construction phases, promoting community investment and engagement.

Vision for Economic Growth

The demand for electricity in Ontario is on the rise, making these infrastructural enhancements even more crucial. According to Ryan Docherty, the Executive Vice President of Capital Portfolio Delivery at Hydro One, these new lines form part of one of the largest transmission line investment portfolios in Canada. Hydro One is keenly aware that its success is intertwined with the prosperity of Ontario, emphasizing a shared vision of economic growth that aligns with local priorities.

Hydro One is dedicated to helping build a self-reliant economy in Ontario, supporting good jobs, driving growth, and consistently delivering value to the people of the province. The company’s strategic plans reflect an unwavering commitment to nurturing a progressive energy landscape, thus enabling communities to thrive.

Regulatory Compliance

In accordance with Section 92 of the Ontario Energy Board Act, electricity transmitters in Ontario must acquire approval from the OEB for new construction or enhancements to the transmission system. Hydro One's application for both projects includes detailed information regarding each line's route, design, timing, and overall projected costs. This regulatory due diligence underscores Hydro One's dedication to transparency and accountability in its operations.
