​Project update - March 2021

On January 19, 2021, EPCOR received approval from the AUC to proceed with the Meadowlark Substation Switchgear Replacement Project (Decision 26242-D01-2021). Construction is planned to begin in spring 2021.

Project details

New indoor electrical equipment, a switchgear assembly, is needed at the existing Meadowlark Substation to maintain reliability and to better meet demand for power in the area. In addition, a ductline needs to be built from the substation, across 84 Avenue to a manhole.

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.

Explaining a ductline

A ductline is a collection of conduit (PVC pipe) that hold the wiring for a building and protect the distribution circuits from being damaged. This work will involve open cut construction across 84 Avenue to a manhole in the middle of the roadway and placing the circuits in a concrete casing.

Project Timeline

The tentative schedule of work would be as follows:

Phase 1

Replacement of one switchgear inside the substation building and the installation of the ductline is expected to begin in spring/summer 2021 and will take approximately one year.

Phase 2

Once Phase 1 has been completed, the replacement of the remaining switchgear located inside the substation building will begin and is expected to be completed by fall 2023.

Construction details

​Construction noise

The work will create typical noise associated with construction. 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.

Hours of construction

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

Road closures

Access along 84 Avenue west of 154 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.

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.
