​Current and u​pcoming Rossdale projects

​EPCOR is responsible for building, maintaining, and upgrading the electrical transmission and water distribution systems in Edmonton. As the system ages, infrastructure requires maintenance and upgrades to ensure the safe, reliable delivery of power and water.

​El​e​c​tricity projects at Rossdale

​EPCOR is responsible for building, maintaining, and upgrading the electrical transmission and distribution system in Edmonton. In order to continue delivering safe and reliable power to our customers, the electrical infrastructure require​s maintenance and upgrades. In 2022, EPCOR plans to complete five electricity projects within EPCOR’s Rossdale site.​

Rossdale Substation Transformer Bushing Replacement Project (October 2022)

In October 2022, EPCOR will be doing work at the Rossdale Substation to replace a part on a transformer that has reached its end of life. Transformers play an important role at our substations; they lower the voltage of power to a level that can be used by homes and businesses in the area. The part being replaced is called a bushing and it helps electrical energy pass through the transformer. This work will take place within the fenced substation boundary and is expected to take approximately one month to complete.

Transmission Line Degassing Project (May 2022)
Starting in May 2022, EPCOR will be doing maintenance on one of our underground power lines. Some of our underground power lines are insulated in fluid filled pipes and occasionally gases may build up in the fluid, which then need to be removed. We will be setting up equipment within EPCOR's Rossdale site to remove the gases and then reinsert the fluid back into the pipes using the Bellamy pump station (shown on the map). This work is expected to take approximately two months to complete.
RS5 Underground Transmission Line Removal & Fibre Optic Cable Installation Project (Fall 2022)

An underground transmission line that connects the Rossdale Substation to the Strathcona Substation has reached its end of life and needs to be removed. This project involves taking out the old transmission line and cleaning the pipe it was contained in so it can be used for other utilities, such as fibre optic cables. To complete this work, EPCOR will be working within the Rossdale Substation to remove existing equipment. Due to the sensitive nature of the area, we will work with archaeology experts to monitor any ground excavations that occur on this project. This work is expected to start in Fall 2022 and take approximately four months to complete.​​ More information on the RS5 Underground Transmission Line Removal Project.

Thermal Backfill Replacement Project (October 2022)

In 2021, EPCOR completed a project which involved replacing the soil backfill around one of our underground transmission lines within the Rossdale Substation.

It has been identified that additional work is required to replace the soil backfill around this location. Due to the sensitive nature of the area, we will work with archaeology experts to monitor any ground excavations that occur on this project. The existing backfill material will be removed using both hand excavation and a hydrovac to the depth of 1.5 metres. Once the old backfill is removed, a new high thermal backfill material will be put in its place to ensure the cables do not overheat. This work is expected to start in October and take approximately one week to complete. 

Rossdale Substation Circuit Breaker Replacement Project (September/October 2022)

A circuit breaker in the Ros​sdale Substation is nearing the end of its useful life and need to be replaced. The new breaker will be placed in the same location as the old one shown in green on the map. This project is expected to start in September/October 2022 and take approximately five weeks to complete.​

Rossdale Substation Cable Termination Replacement

​Starting August 29 for approximately two weeks, we will be repairing a high voltage cable termination inside the Rossdale Substation. The substation converts electricity from high voltage power lines (transmission lines/cables) to lower voltages that can be distributed to homes and businesses in the area. A cable termination is the point where a transmission line/cable starts or ends. The repair will create noise typical to construction. Work hours will be Monday to Friday from 7:30 a.m. to 5:00 p.m.; however, occasional evening and weekend work may be required.​

Electricity project construction impacts​

Following is a list of what you can expect during our project work in the Rossdale area.


This work will be noisy at times and involve the use of hydrovac trucks, a horizontal directional drill, and other 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, we will work with the City of Edmonton to obtain the necessary permits.

Power outages

Power outages will not be required to complete these projects. 


All work areas will be maintained in a safe and secure manner. All construction activities will be performed in accordance with the City of Edmonton's bylaws, Occupational Health and Safety requirements and EPCOR's strict health, safety, and environmental procedures and guidelines.​

The Alb​​erta Utilities Commission (AUC)

Alberta's electric utilities are regulated by the AUC. The AUC is an independent quasi-judicial agency that ensures that the delivery of Alberta's utility service takes place in a manner that is fair, responsible and in the public's interest. EPCOR's electricity projects must be approved by the AUC before construction can begin. For more information about the AUC, please visit the AUC's website​.​


Wat​er ​projects​​ at Rossdale​​

Locating underground utilities for flood protection project

​In order to protect the Rossdale Water Treatment Plant in a situation where the North Saskatchewan River overtops its banks, EPCOR is working with the community to plan and design flood barriers. 

In mid-February, EPCOR began excavating certain locations where flood barriers will be constructed to confirm the types of utility infrastructure that exists underground in the area. Excavation work outside the plant fenceline is expected to begin on March 21.

It is important for EPCOR to understand what utilities are underneath the planned flood barrier locations at Rossdale so that we can properly plan for future construction of the barriers. Construction on the flood barriers is not anticipated to begin before 2024 as EPCOR is currently in the initial planning and design work of the project.

​Lead management st​​​​rategy 

In 2019, Health Canada recognized the serious health impacts of lead by lowering the maximum allowable concentration in drinking water. While there is no lead in drinking water when it leaves our treatment plants, lead can still leach from home fixtures and other plumbing surfaces.

EPCOR has developed a multi-pronged lead management strategy that includes controlling corrosion in water services, plumbing and fixtures. As part of this strategy, we are constructing special facilities where we will add orthophosphate to the treated water at both the E.L. Smith and Rossdale water treatment plants. While this work is happening entirely within our sites, residents may notice noise, traffic and other impacts typical to construction.

The new facilities are expected to be in service by early 2023.
