​We have received approval from the AUC to proceed with the Upgrades to the Garneau Substation Project (located at 11117 85 Avenue). Have a look at our latest update from April 2020.

Project update

In December 2018, a project package was sent to landowners, occupants and residents describing the proposed project and the AUC regulatory process.

On March 12, 2020, EPCOR received approval from the AUC to proceed with the Upgrades to the Garneau Substation Project as part of the West Edmonton Transmission Upgrade Project (Decision 23943-D01-2020). This work is scheduled to begin this year. Stakeholders directly adjacent to the project will receive further notice setting out timing and construction impacts when details are confirmed.

Next steps

We're preparing for the construction phase of the project. Communities and stakeholders in this area received an update to inform them of the AUC's decision. Construction is scheduled to begin in August 2020 for this project. Stakeholders directly adjacent to the project will receive a notice setting out construction details and a schedule. Stakeholders who are not directly adjacent to the approved project will only receive information about the project by request. To request construction details, please call (780) 412-4040 or email

Project overview
​The approved project includes:
  • Replacing the three existing transformers. Two of the new transformers will be replaced in the same location as the existing transformers, while the third transformer will be moved further west to allow for safe access to the equipment during construction and for maintenance.
  • Expanding the substation yard. To accommodate the relocation of the new transformer, the substation yard will need to be expanded. This will involve removing the EPCOR-owned house directly west of the substation and expanding the fence line by approximately 10 metres by 36 metres.
  • Replacing the existing fence. To improve security around the substation, we will also be replacing the existing six-foot fence with a new eight-foot fence. The new fence will look similar to the existing fence.
Project timeline

EPCOR is preparing for the construction phase of the project. Construction is scheduled to commence in summer 2020. Please note the timing and details may be adjusted as activities are finalized.

EPCOR is closely monitoring the situation related to the COVID-19 outbreak. We have plans in place to manage disruptions or emergencies and we are committed to providing the services our communities count on. Protocols have been put in place for our employees while performing essential work to protect the health of our teams and our customers. We also request homeowners take precautionary measures by maintaining a safe, two meter distance from our crews.

Construction details

​In your neighbourhood

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 is necessary to temporarily exceed noise levels, we will work with the City of Edmonton to obtain the necessary permits.

Road closures

Access down 85 Avenue between 112 Street and 111 Street may be limited during some stages of construction. We will work diligently to reduce possible impacts and provide those affected by construction with more detailed information prior to any work starting.

Power supply

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

On site

Hours of operation

We anticipate our hours of work for this project to be Monday to Friday 7:30 a.m. to 5:00 p.m.; however, occasional evening and weekend work may be required.

Work space

All proposed work spaces for the project will be safe and secure, and construction activities will comply with 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 the project.

​What is a substation and transformer?

A substation is a part of the electrical system that connects two or more power lines. The Garneau substation converts electricity from higher voltage power lines (transmission lines) to lower voltages that can be safely distributed to homes and businesses in the area. This conversion is done using a transformer.

Regulatory process

Participate in the process

EPCOR believes in listening to and engaging stakeholders. While the COVID-19 social distancing requirements mean we cannot hold a project open house at this time, we are pleased to connect with you through phone or email. Over the next few weeks, we will contact stakeholders directly adjacent to the project for the opportunity to provide input.

Community input and involvement is an important part of our decision-making. If you have any questions or would like to provide input on the project, please contact us:
