Prince George to Glenannan Transmission Project

Demand is growing from customers in the North Coast area for clean, reliable power to support electrifying their operations to reduce greenhouse gas emissions.

The current 500 kV line 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.
 

We're planning to add a new transmission line and associated infrastructure from Williston Substation to Glenannan Substation:

• New, approximately 170 km, 500 kV transmission line.
• Expanding Williston Substation to the east to accommodate required equipment.
• Expanding Saranovich Capacitor Station (CAP 1) to allow the line to carry more electricity reliably.

This project is part of the North Coast B.C. electrification initiative which also includes plans for new lines from Glenannan Substation to Skeena Substation as part of the Glenannan to Terrace Transmission project.
 

We've identified a route corridor shown in the figure below as well as options along two parts of the route as shown in the figures that follow:

Routing Options – Williston to Node 5

The proposed transmission line routes have not been determined. They may be north or south of the existing line.

Join us at an open house to learn and provide your feedback about:

• North Coast electrification.
• The Prince George to Glenannan Transmission Project, including route options under consideration (detailed route option information will be presented at the May 8 to 10 and open houses).
• Our early plans for the Glenannan to Terrace Transmission Project.

We look forward to discussing our plans with you.
