​This fall, as part of the approved Upgrades to the Garneau Substation Project, EPCOR will remove the EPCOR-owned residence that is directly west of the Garneau Substation located at 11123 – 85 Avenue and expand the substation yard to accommodate the relocation of a new transformer. Please refer the September 2020 - Construction Notice.

Project overview

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).

These upgrades entail the replacement of the three existing 72/15 kV transformers in the Garneau Substation with three new 72/15 kV transformers of higher capacity. Two of the transformers will be replaced in roughly the same location as the existing transformers, while the third will be moved further southwest to allow for safe access to the equipment during construction and for maintenance (see site layout on page three). To accommodate the relocation of the new transformer, the substation yard will be expanded. This will occur when the EPCOR-owned house directly west of the substation is removed. The new building will form part of the fence portion on the west side.

To improve security around the substation, we will replace the existing six-foot fence with a new eightfoot fence. The new fence will look similar to the existing fence.

Next steps

We are beginning the construction phase of the project. Communities and stakeholders in this area received a Construction Notice to inform them of the upcoming construction activity.

Construction is scheduled to begin mid-September. The house demolition and substation expansion is scheduled to begin mid-September 2020 and is expected to be completed by end of December 2020, weather permitting.

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 consultation@epcor.com.

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

Construction will commence mid-September 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

All work will be completed on EPCOR property within a temporary fenced area of the Garneau Substation. During construction, residents can expect to see vehicles and equipment entering and exiting the substation.

In addition:

  • A pit will be excavated at the south end of the expanded substation yard for the installation of a transformer pad.
  • A second pit will be excavated on the west side of the existing substation building to accommodate a new duct line.
  • The existing EPCOR-owned residence directly west of the substation will be demolished in a safe, secure manner. All refuse and materials will be cleaned up at the completion of the demolition.
  • A site trailer will be placed on the north side of the existing substation building, within EPCOR property.

EPCOR does not anticipate any power service interruptions as a result of this work.

Residents will experience noise typical to construction as various equipment and trucks will be used for material delivery, excavation, equipment installation and surface restoration. We will 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.

Affected landscaping, pavement and sidewalks within the work area will be restored to their original condition when weather permits.

Traffic accommodations

  • No permanent road closures will be required for the duration of this construction work. Access down 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. These closures will be done in accordance with the City of Edmonton OSCAM permitting system.
  • Flag people will be used to direct the public during equipment deliveries.

FAQs

​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:
