Hidden in plain sight: $1-billion BC Hydro substation below downtown Vancouver park and school

BC Hydro has unveiled a more detailed design concept for a new portion of Nelson Park in downtown Vancouver’s West End neighbourhood, highlighting the future outdoor play space for the replacement Lord Roberts Annex Elementary School.

This play area will be built atop the utility’s new underground substation, effectively serving as the facility’s lid.

The new West End Substation project is now a decade in the making, with BC Hydro completing financial and land use agreements with the Vancouver School Board and Vancouver Park Board at various junctures over the years.

There is a need to build this substation to not only meet the long-term demand needs of the downtown Vancouver peninsula’s new developments, but also to improve reliability and seismic resiliency. This new substation will replace the existing above-ground, 1950s-built Dal Grauer Substation, located on Burrard Street — immediately adjacent to Scotiabank Theatre.

This new substation will necessitate the demolition of the existing Lord Roberts Annex structure at the park, with its students temporarily relocated to the new Seaview Elementary School in Coal Harbour, which will reach completion soon and open in September 2026.

BC Hydro previously agreed to provide the School Board with at least about $75 million — including capital contributions towards building the new Seaview and future Lord Roberts Annex schools — and the Park Board with $8 million.

With the temporary replacement school capacity now almost ready, BC Hydro is advancing the detailed design process of its new substation, which will have five underground levels and some above-ground features up to 25 ft. in height, such as a secure small entrance building for crew, air venting structures, and integrated fencing — all designed in a way to “reduce their visual presence, maintain safety, and contribute positively to the streetscape.”

The substation’s lid will include a school playground, a large play field, basketball courts, and outdoor learning spaces.

“The West End Substation represents a unique opportunity to deliver vital electrical infrastructure while enhancing public amenities in the downtown core,” reads BC Hydro’s submission to the City of Vancouver.

“Through its underground design, collaborative planning process, and careful integration with the school and neighbourhood context, the project balances technical requirements with community values. The result will be a safe, sustainable, and future-ready facility that supports both Vancouver’s energy resilience and its public realm.”

The electric utility has provided the municipal government with a “development review” submission for public and City staff input on the design only — not for approval. This should not be confused with a development permit application. Under provincial legislation, BC Hydro does not need to seek permission from a municipal government to build electrical infrastructure.

BC Hydro’s project is designed by engineering firm WSP, architectural firms Kasian and Architecture 49, and landscape architectural firm PFS Studio.

Separately, City staff note that they expect a development permit application submission from the School Board in Spring 2026 to build the new Lord Roberts Annex building, which will be built slightly to the west of its existing footprint within the park — at the southeast corner of the intersection of Bute Street and Nelson Street.

BC Hydro submitted its application to the B.C. Utilities Commission in late 2025 for the final approval it needs from the province’s independent energy regulator to advance the project. According to the application, the new substation carries a preliminary estimated cost of $1.028 billion, with a potential range of between $756 million and $1.391 billion based on an estimated accuracy range of -27 per cent and +36 per cent. The preliminary design is expected to be completed in April 2026, and an updated cost estimate will be made in June 2026.

The electric utility intends to begin construction no earlier than late 2026. Once construction begins, it will take up to five years to build the new substation, with approximately three years for excavation and building the structure up to ground level, including the roof to form the lid. Then another two years will be required for the installation of the complex equipment within the underground volume.

There will be some short-term impacts to other areas of Nelson Park outside of the substation footprint, specifically new trenches to create new underground electrical lines.

The application to the regulator notes that the Dal Grauer Substation will continue to operate for at least five years after the new West End Substation begins its service. The decommissioning process will need some environmental remediation in addition to the removal of all equipment. No future use of the property has been determined, but it is acknowledged that the building has heritage value given its architectural design.

In the 2030s, BC Hydro also intends to replace the aging Murrin Substation in Chinatown with a new facility in East Vancouver.

In a February 2026 bulletin providing an update on its planning process for the new Lord Roberts Annex school, the School Board states the future new replacement school building is intended to have a capacity for 510 students, including 60 in Kindergarten and 450 in Grades 1 to 7.

This will be a three-storey school building, with the excess heat from the substation used for the school to enhance the project’s sustainable design.

The School Board also warned that there has been a steep construction cost escalation ever since it finalized the original agreement with BC Hydro in 2018, and provincial funding is needed to fully cover the costs. As provincial funding has not been confirmed, the School Board is working with BC Hydro to design the shared elements with the substation, such as the underground structures — a strategy that “future proofs the site so the school can be integrated with the new substation once full funding is secured.”

With the opening of Seaview Elementary School later this year as temporary replacement capacity, demolition work on the existing Lord Roberts Annex building is expected to begin in late Fall 2026. The School Board anticipates that a building permit application submission for the new school will be made in 2027. Upon completion, Lord Roberts Annex — combined with Seaview — will provide a major net gain in elementary school capacity for downtown Vancouver school catchments.
