Project Overview
Location: Prince George to Terrace, British Columbia (450 km corridor)
Project Type: High-voltage electricity transmission (500 kilovolt)
Total Investment: CAD $3-5 billion
Proponent: BC Hydro (Crown corporation)
Indigenous Partners: Seven First Nations through K'uul Power consortium
Status: Co-ownership term sheets signed July 2025; environmental review underway
Timeline: Construction 2026; completion 2029-2030
Phase 1 focuses on the first major segment of the build-out, advancing new and upgraded transmission infrastructure from the Prince George/Williston area toward the central-north corridor (including the Prince George to Glenannan/Fraser Lake reach). BC Hydro describes Phase 1 as an approximately 170 km line from the Williston Substation (near Prince George) to the Glenannan Substation, along with associated upgrades. B.C.’s project framing also describes Phase 1 as running from Prince George to Fraser Lake (about 164 km).
Phase 2 is the central build segment that increases transfer capacity into the Terrace area by constructing new 500 kV infrastructure between the Glenannan, Telkwa, and Skeena (Terrace) substations. This phase is intended to improve reliability, support community electrification, and enable clean-power supply for major industrial growth on the North Coast, while also strengthening regional telecommunications capacity through fibre additions.
Phase 3 is described as new transmission infrastructure north of Terrace, connecting towards Aiyanish and Bob Quinn Lake, with planning underway. It is positioned as a key element of a wider clean energy and economic corridor that supports critical minerals development and export-oriented LNG projects, while contributing to emissions reductions and long-term regional growth.
