Hydro One seeks approval from the Ontario Energy Board to build the Northeast Power Line and the Longwood to Lakeshore Transmission Line
Hydro One doubles down on Ontario’s grid with $3B twin-line filing, but regulators keep a tight hand on cost recovery.
The most recent release (May 19, 2026) announces that Hydro One has filed two leave-to-construct applications with the Ontario Energy Board (OEB) for major new transmission projects: the Northeast Power Line (a 500 kV line from Hanmer to Mississagi, ~$1.8 billion, targeting 2029 in‑service) and the Longwood to Lakeshore Transmission Line (a 500 kV line from Strathroy-Caradoc to Lakeshore, ~$1.2 billion, targeting 2030). Both projects incorporate the First Nation 50:50 equity partnership model.
Earlier news from May 13 reports solid Q1 2026 results (EPS $0.65, revenues up 10% YoY) and a CEO transition. On April 7, the OEB denied recovery of $223 million in March 2025 ice‑storm costs, a material negative. Prior to that, the company was selected for the Red Lake (April 23), Sudbury‑Barrie (Feb 9) and Greenstone (Jan 28) transmission lines, all under the First Nation equity model. Q4 2025 results (Feb 13) showed EPS $0.39 and a $1.6 billion sustainable‑financing note issuance. A sustainability report (May 7) highlighted Indigenous procurement exceeding targets.

The May 19 filing is the natural next step for projects that were already designated and publicly communicated. Both lines had been referenced in earlier project selection announcements; seeking leave‑to‑construct is an expected regulatory milestone. The news adds no unanticipated scope, cost overrun, funding change, or timeline acceleration. Markets had already priced in these projects via the selection announcements and Hydro One’s multi‑year capital plan. Therefore, the event is incremental and does not, by itself, alter the investment thesis.
The April 7 OEB denial of $223 million in ice‑storm cost recovery was the last material development, but that was absorbed by the stock (a temporary pullback that later recovered). Q1 2026 earnings confirmed steady operational performance, and the CEO succession appears orderly. The most recent filing reinforces the growth pipeline but does not introduce new material information.
