McLellan Substation Upgrade
McLellan Substation, built in the 1950s, converts 230kV electricity to 25kV to power homes and businesses in Surrey and Langley.
The Surrey/Langley region, one of Canada's fastest-growing areas, is receiving major upgrades at McLellan Substation to meet rising electricity demands. Serving over 49,000 customers, the station at 196 Street and 54 Avenue is being refurbished and expanded to ensure reliable power across the area and to support the growth.
What's new
September 2025
Tree and vegetation clearing activities began in August and are expected to continue until early November.
We’ve preserved a 550m² tree retention zone between the substation and Brydon Lagoon. We’ve also preserved about 175 metres of existing vegetation along our eastern property line.
We’ll continue to work with local government and stakeholders as we develop a plan for landscaping and restoration after the substation expansion work is complete.
To ensure continued and reliable electricity in east Surrey and Langley City, we're upgrading the McLellan Substation located at 196 Ave and 54 St. The expansion will be completed in two phases:
Phase 1
- Refurbish existing feeder positions with new equipment to ensure continued reliability of power to the Surrey / Langley area.
- Add new feeder positions to support growth.
- Install a new shunt capacitor bank to relieve voltage constraints to support load growth in the Central Fraser Valley Regional Transmission System.
Phase 2
- Clear trees from substation property.
- Expand the substation to the east to add a new transformer and associated equipment.
- Add new feeder positions to utilize the additional capacity provided by the new transformer, thereby doubling the capacity of the substation.
