North Coast Transmission Line Phase 1: Prince George to Glenannan 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 capacity and electricity from the Prince George to Terrace Capacitors project, which is currently under construction, is already fully subscribed. We're proposing to expand our transmission system to meet projected demand.

North Coast Transmission Line Phase 2: Glenannan to Terrace Transmission, covers the area from Glenannan Substation to Skeena 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 continuing discussion with current and potential customers to identify whether additional infrastructure will be required south or west of Terrace.

We began engaging with communities along Phase 1 of the line in 2023, during our early project planning. We will continue to share updates as we move toward and through construction.

We are also working with our First Nations partners. This supports our commitment to co-design the environmental review and explore First Nations co-ownership of the North Coast Transmission Line, along with other opportunities for Indigenous participation.

As planning for the proposed projects continues, we'll host more open houses and other events so we can share updates and hear your feedback.
