George Massey Tunnel Transmission Relocation Project

As a new tunnel is planned, a section of our power line needs to be relocated

The Province is proposing to replace the existing four-lane George Massey Tunnel with a new, eight-lane immersed tube tunnel, and will decommission the existing tunnel once the new tunnel is in operation.

A section of one of our power lines crosses the Fraser River through the George Massey Tunnel so we need to relocate it before the tunnel is decommissioned.

This power line is a critical part of the electricity grid that supplies power to Richmond. It helps us keep the lights on for over 30,000 customers  in the area.

We deliver reliable, clean energy to homes and businesses across British Columbia. We depend on our power lines to ensure electricity gets to where it's needed.

The Province is proposing to replace the existing four-lane George Massey Tunnel with a new, eight-lane immersed tube tunnel, and will decommission the existing tunnel once the new tunnel is in operation.

We operate a 12-kilometre, 230-kilovolt power line from Arnott Substation in Delta to Steveston Substation in Richmond, serving approximately 30,000 customers. Approximately 700 metres of this line is underground in the existing George Massey Tunnel. With the tunnel planned for decommissioning, we need to relocate this section of the power line across the Fraser River.

We’re examining three alternatives to relocate a section of the existing power line that is currently located underground in the George Massey Tunnel. See the maps below (this information is at a conceptual level and is subject to change):

Alternative 1: Overhead line

A new, overhead line across the Fraser River to connect with existing overhead lines in Delta and in Richmond.  This line would be built adjacent to the Province’s proposed immersed tube tunnel.

The George Massey Tunnel Transmission Relocation Project is in its earliest days and a project timeline hasn’t been established. We will identify an estimated project timeline after a leading alternative has been identified in 2023.

In the meantime, here’s what we’ll be doing over the next year:

  • Environment, archaeology, and engineering desktop studies – Summer to Winter 2022
  • First Nations consultation and stakeholder engagement – ongoing

Our project is just getting underway and we will be hosting consultation events on the project alternatives later this fall.

In the meantime, if you are part of a community group and would like us to provide you with a high-level overview of the project and the alternatives we’ll be studying, please reach out to the project team at projects@bchydro.com
