Drama About the Proposed West End Substation 

By Bill Andrews and Tom Hackney

The Government of BC announced on September 9 that the West End Substation project is going ahead, even though the BC Utilities Commission has yet to rule for, or against, the project after an intensive proceeding and having received final arguments. Very strange! Has the Government overridden the BCUC without public notice? Is the Government using ‘the power of positive thinking’ to pressure the BCUC? Is the Government implying that BCUC approval is a foregone conclusion? Was the media release simply a ‘boo-boo’? We simply don’t know. 

BCSEA has been intervening actively in the BCUC’s proceeding since January 2026 (see: Electrical Infrastructure in Vancouver’s West End.) In August 2026, BCSEA filed its final argument.

BCSEA told the BCUC that the West End Substation Project is needed for BC Hydro to provide reliable electricity service in the Downtown Vancouver Electricity Supply (DVES) System. 

BCSEA said the existing Murrin Substation and Cathedral Square Substation, that now serve Downtown Vancouver, are not suitable for the future. BCSEA cited seismic risks, insufficient feeder positions for new large customers, incompatibility with conversion of the distribution system to 25 kV, reliability risks, and safety risks. 

BCSEA supports low-carbon electrification in BC (of course) and is happy that the West End Substation Project (together with the East Vancouver Substation project) would facilitate the connection of new large customers, some of which are electrification loads. 

That said, the “need” for the West End Substation Project is not driven by load forecasts but by the issues and constraints in the existing Downtown Vancouver Electricity Supply System. BCSEA argued that completion of the West End Substation (and the East Vancouver Substation) would be sufficient to serve Downtown Vancouver over the next 20-years and possibly beyond. The two new substations would replace the aged Murrin Substation and the Dal Grauer Substation. 

In its final argument, BCSEA supported BC Hydro’s identification of, and rejection of, five potential alternatives to the West End Substation Project. Doing nothing would not address the existing limitations in the DVES System. Deferring the Project would reduce the near-term costs of addressing deteriorating assets but would not provide a timely solution to the existing limitations in the DVES System. Upgrading the Mount Pleasant Substation would not allow BC Hydro to fully offload Murrin Substation. Constructing only the East Vancouver Substation (and not the West End Substation) would not be technically feasible (The underground utility corridors in the Downtown Vancouver peninsula are too congested to accommodate the feeders required to re-supply the loads served by both Murrin and Dal Grauer Substations.) 

BCSEA concluded that there is no preferable alternative site for a new substation in the West End. The Project will certainly have adverse impacts during and after construction, but BCSEA argued that these impacts have been mitigated as much as possible.
