​Project update - October 2022

The construction phase of the project is underway. The construction of the new building has been completed. The new electrical equipment is expected to be in service by Summer 2023 with the decommissioning of the old electrical equipment complete by Winter 2023.​

The work for the Garneau Substation Upgrades Project is currently underway.

Project overview

On September 28, 2020, EPCOR received approval from the AUC to proceed with the Garneau Substation New Building and Switchgear Project (Decision 23943-D01-2020).

The approved project includes:

  • New indoor electrical equipment, a switchgear.
  • To accommodate the new equipment, a new substation building where the EPCOR-owned house was, directly west of the substation will be built.

The new building

To suit the surrounding area, the new building will look similar to other single family residential homes in the neighbourhood. The illustration on under Maps and renderings shows the proposed new building. The dimensions of the new building will be approximately 22 metres long by 10 metres wide, which is similar to the EPCOR-owned house. The walls will be made out of concrete, closely matching existing buildings within the neighbourhood.

Explaining switchgears

A switchgear is a part of the electrical system that serves to split electricity from a transformer to multiple distribution cables. This is similar to your house electrical panel in that it takes the incoming power and splits it amongst the many areas of your house. The switchgear performs the same function for a grouping of residential, industrial or commercial customers.

Construction details
Construction Noise

The work will create typical noise associated with construction. We will take measures to ensure we comply with the City of Edmonton's Community Standards Bylaw for Noise Control. If it's necessary to temporarily exceed acceptable noise levels, we will work with the City of Edmonton to obtain the necessary permits.

Hours of Construction
Typical hours of construction will be Monday to Friday from 7:30 a.m. to 5:00 p.m.. If required, these hours may be extended, and construction may occur on Saturdays and Sundays from 9:00 a.m. to 6:00 p.m.

Traffic Accommodations
Access along 85 Avenue between 112 Street and 111 Street may be limited during some stages of construction. Temporary lane closures to accommodate the movement of equipment in and out of the substation site may be required. Flag people will be used to detour traffic and pedestrians around the work site during these times.

Power Supply
No interruptions to power services are anticipated as a result of this project.

Work Space
All work areas will be safe and secure. All construction activities will be in accordance with the City of Edmonton bylaws, Occupational Health and Safety requirements and our strict health, safety and environment program. We do not anticipate any adverse environmental impacts associated with this project.

Construction work and COVID-19
COVID-19 protocols are in place to protect the health of our teams and our customers. We also request you take precautionary measures by maintaining a safe, two-metre distance from our crews and contractors.
