Partial Cable Replacement, Coquitlam
We’re undertaking a project to replace a 1.3 kilometre section of an existing underground, oil-insulated power line that was installed in the 1970s with a new oil-free power line.
We're planning for construction and will reach out to the community in the coming months to share our plans and ask for feedback.
The project is located along an existing right-of-way that runs between Lougheed Highway and Spuraway Avenue in the Ranch Park neighbourhood of Coquitlam.
|Project launch||Fall 2020|
|Engineering and environmental studies||Spring 2021 to summer 2023|
|Design of new underground cable||Summer 2023 to summer 2025|
|Construction start||Summer 2025|
|Project completion||Winter 2027|
We’re planning to replace 1.3 kilometres of an existing underground oil-filled cable between Spuraway Avenue / Pinnacle Street and the Como Lake Substation at Como Lake Avenue/Lougheed Highway in Coquitlam.
The existing cable section will be replaced with a new underground oil-free insulated cable. At road intersections, we'll build underground reinforced concrete containers, called 'duct banks', to house the cables.
This section of underground, oil-filled cable that we’re replacing is old and leaks have occurred at the cable’s joints due to high pressure from the elevation change between the top of the slope at Spuraway Avenue/Pinnacle Street and Como Lake Substation (at Como Lake Avenue/Lougheed Highway) – an elevation change of 170 metres.
We’ve successfully located and cleaned up past leaks; however, due to the age and accumulated fatigue at this location, we anticipate that more leaks will occur, requiring more costly repairs.
Replacing this section of cable with a new, oil-free insulated cable will extend the life of the cable and ensure it can run efficiently for many more years.
We’re in the early stages of this project and our studies and design will inform the project budget and construction schedule. We anticipate a construction level budget will be completed by the end of 2025.
An environmental overview assessment is underway to identify environmental features overlapping or directly adjacent to the cable alignment. This information will inform the design of the project and the required mitigation and monitoring plan for construction.
