Pemberton Substation Rebuild Project

This project will replace equipment that is near end-of-life and prepare the substation for future upgrades.

It will also remove equipment with Polychlorinated Biphenyls (PCBs), part of our PCB electrical equipment removal strategy that meets stringent federal regulations.

These improvements will ensure the station continues to safely and reliably operate for our customers.

The Pemberton substation has been in service since the 1970s, serving more than 3,600 customers in Pemberton and the Sea-to-Sky region. The station is supplied with electricity from one 230-kilovolt transmission line from Bridge River generating facilities in Shalalth.

We need to upgrade the substation to:

• Replace major equipment that is near end-of-life
• Remove electrical equipment containing PCBs
• Improve station layout for future upgrades

The Pemberton Substation is an existing substation on Pemberton Portage Road near Aspen Boulevard.

The project will ensure we continue to provide clean, reliable energy to communities in Pemberton and the Sea-to-Sky region that are served by the substation while preparing for future upgrades.

This project will require an expansion of the substation within the existing property lines to make room for the new equipment. It will require changes to the surrounding vegetation and parking at the Pemberton Health Centre. We will communicate more details as they become available.

Phase one construction starts in June 2023. Preliminary design work continues on the second phase of work, which has a planned start date of fall 2024 (previously spring 2024). The in-service date for the project is anticipated to be June 2027.

During the planning phases of the project, desktop and field environmental studies will be undertaken to investigate archaeological potential, wildlife and wildlife habitat, vegetation and soil characterization.
