Victoria to Esquimalt Cable Replacement Project

This emergency project is necessary to replace an existing underground, oil-insulated transmission cable that is at the end of its serviceable life.

What's new

Thank you for those who attended our Virtual Open House session on February 29, 2024.

Replacing a direct-buried, oil-filled cable with an oil-free cable that is constructed in a duct bank.

The existing underground cable will be decommissioned once the new cable is energized.

It is one of four underground transmission cables critical to the electricity supply for Greater Victoria and was installed in 1980.

Widespread cable corrosion was discovered during recent repairs, increasing the risk of failure.

The project will install the latest technology in transmission cables to ensure safe and reliable electricity for decades.

The Victoria to Esquimalt Cable Replacement Project is located along an existing right-of-way, approximately 2.7 kilometres in length, that runs between Horsey Substation near downtown Victoria and Esquimalt Substation in Esquimalt. The route includes a 0.4 kilometre submarine crossing along the bottom of the Gorge Waterway between Victoria and Esquimalt. The project is at an early stage of design and some routing variations may occur.
