Project overview

This project involves constructing approximately 9.5 km of above-ground 72 kilovolt (kV) transmission line from the Poundmaker Substation (18944 105 Avenue) to the Meadowlark Substation (15404 84 Avenue), as well as modifications to both the Meadowlark and Poundmaker Substations. The project was approved by the Alberta Utilities Commission on March 12, 2020 (Decision 23943-D01-2020). This project is expected to be completed in fall 2021.

​Construction phases and timeline

Construction phases

Construction of the transmission line is scheduled to begin in October 2020 and will be completed in phases.

Phase One: Installation of Power Poles on Segment 2 along Whitemud Drive (October to January)

The first step in building this segment of the transmission line is to install power poles. This will involve excavating holes and using a crane to install the poles. To set up the crane, temporary lane closures will be required on Whitemud Drive in the areas where the construction is taking place.

Phase Two (Early 2021)

Involves the installation of power poles on Segment 1 along Anthony Henday Drive and Segment 3 along Whitemud Drive and north on 156 Street. Existing distribution lines will be relocated during this phase at the required locations.

Phase Three (Summer 2021)

Involves stringing the transmission cables and fibre optic cable on the new power poles. Transmission cables, also called conductors, are the wires you see strung on power poles. Fibre optic cables provide a communications link between neighbouring substations and EPCOR's control centre. To minimize disruption to traffic, the cables will be strung in stages. Locations where the stringing will occur will have additional construction activities, such as temporary lane closures and construction equipment.

As the project progresses, additional notices will be delivered to stakeholders along Segments 1 and 3 prior to construction.


The West Edmonton Transmission Upgrade Project – Whitemud Drive segment is scheduled to begin mid-October 2020 and is expected to be completed by January 2021, weather permitting.

Typical hours of construction will be from 7 a.m. to 9 p.m., Monday to Saturday. If required, these hours may be extended, and construction may occur on Sundays from 9 a.m. to 7 p.m.


​Construction impacts for phase one work

This section describes construction impacts specific to Phase One

Traffic impacts

Some areas will require temporary lane closures to install the power poles. Typically, these closures will not last longer than two days for each location.

Power outages

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


This work will be noisy at times and involve the use of hydrovac trucks, drilling rigs, large trucks, cranes and heavy machinery. We will comply with the City of Edmonton's Community Standards Bylaw for Noise Control. If it is necessary to temporarily exceed acceptable noise levels or work outside of typical construction hours, we will work with the City of Edmonton to obtain the necessary permits.

Tree trimming

There may be isolated areas along Segment 2 where tree trimming and removal may be required to accommodate construction activities.

​Construction work and COVID-19

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 you take precautionary measures by maintaining a safe, two-metre distance from our crews and contractors.
