We are proposing the addition of two new 25 kilovolt (kV) circuit breakers inside the Clover Bar substation building (located at 1515-130 Ave).

We believe in listening to and engaging stakeholders. Community input and involvement is an important part of our decision-making and we want to hear what you think about our initiatives.

Project details

We are proposing to install two new 25 kilovolt (kV) circuit breakers inside the existing Clover Bar substation building to meet the growing demand for power in your area. The new circuit breakers are a larger version of the circuit breakers found in most homes' electrical panels.

Project timeline and approval process

In April 2017, we applied to the Alberta Utilities Commission (AUC) for approval of the two new circuit breakers. If approved, we anticipate the work to start and finish in fall 2017.

What's a substation?

A substation is a part of the electrical system that connects two or more power lines. The Clover Bar 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.

What's a breaker?

A breaker is an automatically operated electrical switch designed to protect an electrical circuit from damage caused by overload or a short circuit. Its basic function is to detect a fault condition and interrupt current flow.

Construction Details


You can expect to see activity that is typical to construction, including company / contractor vehicles and equipment in your neighborhood. All of the planned work will take place within the existing fenced boundary of the Clover Bar substation. There will be no long term visual impacts.

Construction noise

The proposed work will create typical noise associated with construction. We will take measures to ensure we 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 operation

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.

Power supply

We do not anticipate a planned power service interruption from this work.

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, as well as EPCOR's health, safety and environmental procedures and guidelines.
