North Coast Transmission Line Phase 2: Glenannan to Terrace Transmission

We’re bringing more clean, reliable electricity to the North Coast to foster economic growth and enable our customers to use clean electricity to power their operations and reduce greenhouse gases.

The current 500 kV transmission infrastructure from Williston Substation near Prince George to Skeena Substation near Terrace is reaching its capacity limit and electricity from the Prince George to Terrace Capacitors project, which is currently under construction, is already fully subscribed. We need to expand our transmission system to meet projected demand.

Through North Coast Transmission Line Phase 2 we're proposing to:

• Build approximately 130 km of new, 500kV transmission line from Glenannan to Telkwa Substation.
• Build approximately 145 km of new, 500kV transmission line from Telkwa Substation to Skeena Substation.
• Upgrade Glenannan and Telkwa substations.
• Expand Skeena Substation to the north.
• Expand Palling and Walcott capacitor stations to the northwest.
• Add fibre optic cables on new or existing transmission lines.

North Coast Transmission Line Phase 1: Prince George to Glenannan Transmission covers the area from Williston Substation to Glenannan Substation.

We’re also proposing  upgrades to the existing 500 kV lines from Williston Substation to Skeena Substation, as well as  new transmission infrastructure north of Terrace and in Prince Rupert. We’re also continuing discussion with current and potential customers to identify whether additional infrastructure will be required south or west of Terrace.

We've identified a route corridor shown in the figures below and are working to identify route options where the proposed new transmission line can't parallel existing lines between Telkwa Substation and Skeena Substation.

Glenannan Substation to Telkwa Substation

The proposed transmission line routes in this area will generally parallel the existing transmission lines on the north side of the lines.

Telkwa Substation to Skeena Substation

We presented the leading route for the western end generally adjacent to existing lines at open houses in June and will continue studies on that route moving forward. We continue to discuss routing options in the Telkwa area (i.e., Bulbous Toe area) with First Nations and will identify a leading route in that area at a future date.

We look forward to discussing our work with you.

Engagement with our First Nations partners is also underway, and this aligns with our commitment to co-design the environmental review and explore other means of Indigenous participation.

As planning for the proposed projects progresses, we'll hold more open houses and other events or activities to enable us to discuss our plans with you.
