BC Hydro $200 M Burnaby 60 kV Substation Modernisation
BC Hydro is investing CAD 200 million to modernise and expand the Newell Substation in Burnaby, British Columbia. The 70-year-old 60 kV substation will gain a new power transformer, a new feeder building and underground distribution extensions, improving reliability for around 60,000 existing customers and adding capacity for approximately 15,000 more. This investment is part of a wider programme that also includes upgrades to the Horne Payne, Lougheed and Barnard substations. For context on how distribution-grid renewals align with large utility procurement programmes, see how Italy’s e-distribuzione awarded Hitachi Energy a $209 M HV/MV transformer programme for an HV/MV case study.
1. Project Background: BC Hydro and the Newell Substation Context
1.1 BC Hydro and the British Columbia Grid Overview
BC Hydro is the provincial Crown corporation responsible for electricity generation, transmission and distribution across British Columbia, Canada. The utility serves roughly 5 million customers across approximately 950,000 square kilometres. Its asset base includes 79 hydroelectric facilities, 2 thermal generating stations, and approximately 75,000 km of transmission and distribution lines. Within the BC grid hierarchy, 500 kV and 230 kV form the backbone transmission system, 138 kV and 60 kV serve as sub-transmission and large-customer distribution, while 25 kV and 12.5 kV feed the urban distribution tail.
1.2 Newell Substation History and Current State
Newell Substation was constructed between 1946 and 1955 and has now operated for nearly 70 years. The site sits in the heart of Burnaby, British Columbia, and is interconnected with three neighbouring substations: Barnard, New Westminster and Como Lake. Together these four stations supply a significant portion of the 60 kV network serving Burnaby and New Westminster. As a typical North American urban substation built in the late 1940s and early 1950s, much of its outdoor feeder bay equipment and at least one of its power transformers are at or beyond the end of their design service life.
1.3 Drivers of the Upgrade: Reliability and Capacity
According to Charlotte Mitha, President and CEO of BC Hydro, the investment is “first and foremost about renewing aging infrastructure and maintaining reliable service.” Beyond the asset condition driver, the project also responds to population growth in Burnaby, accelerating housing development, and rapid end-use electrification including heat pumps and electric vehicle charging. The upgrade will improve reliability for approximately 60,000 existing customers and add capacity to serve roughly 15,000 additional customers.
2. Investment Scale and Scope of Work
2.1 The CAD 200 Million Funding Structure
BC Hydro is investing CAD 200 million (approximately USD 200 million equivalent) to modernise and expand the Newell Substation. The funding envelope covers construction of a new indoor feeder building, procurement of a new power transformer, upgrade of the site electrical infrastructure, and underground distribution extensions along Kingsway and Griffiths Drive.
2.2 Main Engineering Scope
The project scope is organised around three core work packages:
| No. | Engineering Item | Key Notes |
|---|---|---|
| 1 | Replace ageing outdoor feeder bay | Demolish open-air air-insulated feeders and rebuild inside a new enclosed building |
| 2 | Install a new power transformer | Replace end-of-life transformer with a modern IEEE C57.12.00 compliant unit, typical rating 30-60 MVA |
| 3 | Upgrade site electrical infrastructure | Including busbars, switchgear, and protection and control systems |
In parallel, underground distribution circuits will be extended along Kingsway and Griffiths Drive to connect the substation more efficiently to surrounding load centres.

2.3 Companion Projects and Coordinated Delivery
The Newell upgrade is not a stand-alone investment. It forms the centrepiece of a wider BC Hydro substation investment programme in Burnaby that includes expansion of the Horne Payne, Lougheed and Barnard substations. Each addresses a different service area’s load growth and housing development needs. Treating the four substations as an integrated portfolio allows BC Hydro to optimise 60 kV power flows and reduce the consequence of any single contingency.
3. Technical Highlights and Equipment Parameters
3.1 The 60 kV Voltage Class Position
Newell Substation operates at 60 kV, which is a core voltage class in the BC Hydro distribution network. The 60 kV level is widely used across western Canada and typically serves large industrial customers, urban distribution feeders, and step-down to 25 kV or 12.5 kV distribution substations. By contrast, 138 kV is generally used for sub-transmission, while 230 kV and 500 kV carry the bulk transmission system.
3.2 Transformer Selection and Replacement Logic
Following North American practice, main transformers at 60 kV substations typically fall in the 20-75 MVA range and are overwhelmingly oil-immersed. Given the original statement that BC Hydro is installing a new transformer to replace end-of-life equipment, the new unit is expected to comply with IEEE C57.12.00 for temperature rise, short-circuit withstand, and losses, and to meet BC Hydro’s internal Tier 2 energy-efficiency specification.
3.3 Feeder Building and the Gas-Insulated Trend
Rebuilding the outdoor feeder bay inside an enclosed building reflects the dominant technical trajectory in North American urban substation retrofits. Inside the building, gas-insulated switchgear (GIS) or equivalently metal-clad switchgear is typically deployed. This approach dramatically reduces the substation footprint, improves pollution performance, and helps the installation blend with the surrounding urban landscape. Newell is widely expected to adopt a similar GIS-based solution. Readers interested in deeper specifications can also explore our large power transformer design knowledge base.
4. Construction Plan and Schedule
4.1 Construction Timeline
According to BC Hydro, construction is already underway as of August 2026 and is expected to be completed in 2031. The roughly five-year window reflects the complexity of building on an operating substation site while keeping the existing 60 kV busbars and transformer in service. The underground distribution extensions along Kingsway and Griffiths Drive will inevitably produce some traffic disruption during trenching and reinstatement.
4.2 On-Site Construction Staging
Because the bulk of construction happens inside the existing substation property, BC Hydro must keep the existing 60 kV feeders and transformer in service throughout most of the works. This implies a phased approach: first build the new feeder building and new transformer foundation; then install, commission and energise the new equipment; finally transfer load and demolish the old assets. During each phase, careful attention is required to live-work safety isolation and to temporary supply schemes.
4.3 Coordination with Municipal Authorities
The road-crossing underground distribution works require permits and coordination with the City of Burnaby transportation and utilities departments. As a provincial Crown corporation, BC Hydro must also satisfy applicable Canadian Standards Association (CSA) requirements and the regulatory oversight of the British Columbia Utilities Commission (BCUC).
5. Industry Significance and the North American Grid Renewal Wave
5.1 A Typical Snapshot of the North American Renewal Wave
The Newell Substation upgrade is far from unique. BC Hydro is simultaneously upgrading Horne Payne, Lougheed and Barnard substations in the same region. Hydro-Québec, the Ontario IESO, and the New York ISO are pursuing similar 60-138 kV urban substation modernisations. The drivers are remarkably consistent: aging assets (a large share of North American substations were built between the 1940s and 1970s and are now in their replacement window), load growth from data centres, electric vehicles and heat pumps, and the integration of distributed energy resources such as rooftop solar and battery storage.
5.2 Implications for Equipment Manufacturers
The North American distribution-grid renewal cycle is pulling direct demand for power transformers, gas-insulated switchgear, and protection and control equipment. Hitachi Energy, Siemens Energy, GE Vernova, Eaton, Hubbell and S&C Electric have all built manufacturing footprints or service networks in western Canada. BC Hydro’s tenders are expected to attract multiple international vendors and will place greater emphasis on local manufacturing presence and field service capability.
5.3 Project Delivery Models
North American substation retrofits are typically delivered through design-bid-build (DBB) or engineering, procurement and construction (EPC) models, with alliance contracting gaining ground on larger programmes. The delivery model for Newell has not yet been disclosed, but given the project scale and schedule, BC Hydro is most likely to adopt an EPC approach supplemented by local subcontractors for civil works and underground distribution.
6. Conclusion
BC Hydro’s CAD 200 million investment in Newell Substation is a concrete expression of the British Columbia grid-modernisation strategy and a microcosm of the wider North American urban distribution renewal cycle. By replacing aging feeder bays, installing a new power transformer, and extending underground distribution, the project will materially improve reliability and add capacity for roughly 75,000 customers across Burnaby and New Westminster.
From an industry perspective, three directions are emerging for 60 kV urban substation modernisations. The first is equipment compaction and the migration to gas-insulated switchgear, which reduces substation footprint, increases personnel safety, and aligns with stricter urban zoning rules. The second is energy efficiency aligned with IEEE Tier 2 and DOE 10 CFR 431 limits, which lowers no-load and load losses and improves total cost of ownership over a 40-year asset life. The third is accommodation of new distributed energy resources including solar, storage and EV charging, which demands bidirectional power flow capability, advanced volt-var control and modern IEC 61850-based protection and communication architectures.
The North American distribution-grid renewal cycle has already begun and will run for at least the next 10 to 15 years. According to industry estimates, more than half of the in-service distribution transformers in the United States and Canada are now over 30 years old, and a significant share will reach replacement age within the current decade. This creates a sustained opportunity for equipment manufacturers, EPC contractors and raw material suppliers alike. The Newell upgrade is therefore not just a single BC Hydro substation project for Burnaby: it is a representative case study for the broader Canadian and North American distribution grid modernisation roadmap.
