Petrolia substation

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, we are completing two projects within the Petrolia Substation.

Project overview

EPCOR plans to complete two projects within the Petrolia Substation:

Circuit Breaker Replacement Project – December 2024
Circuit Breaker Addition Project – September 2024

Circuit Breaker Replacement

EPCOR will be replacing six circuit breakers within the Petrolia substation as they have reached their end of life. A circuit breaker is an automatically operated electrical switch designed to protect an electrical circuit from damage caused by overload or short circuit.

Work is expected to be completed by December 2024.

New Circuit Breaker Project

In order to connect a new distribution power cable to the Petrolia Substation, we need to install a new circuit breaker. This work is to improve reliability in southwest Edmonton. The circuit breaker will be installed within the substation building and is planned for the end of September.

What are circuit breakers?

Circuit breakers are automatically operated electrical switches designed to protect an electrical circuit from damage caused by overload or short circuit.

Hours of work

The typical hours of construction will be 7:00 a.m. to 5:00 p.m. Monday to Friday. These timelines are an estimate and may change based on weather and construction condition.

Work space

All work areas will take place within the substation walls.

Noise

These projects may be noisy at times. 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.

Equipment and vehicles on site

These projects will require a variety of vehicles and equipment within the Petrolia Substation, including cranes, hydrovac trucks, mini trenchers, delivery and hauling trucks and EPCOR vehicles.

Power outages

Power outages are not required to complete these projects.

Safety

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.
