​In March 2016, we submitted a facility application to the Alberta Utilities Commission (AUC) for the necessary approvals required to install new current limiting equipment in the Dome substation (application #21482-A001). If approved, we plan install the new equipment in the spring or summer of 2016.

​Project overview

We need to install a new distribution circuit in the Dome substation to serve increased electrical demand in the area. To protect the new distribution circuit, we are proposing to install new current-limiting electrical equipment in the substation. The current-limited electrical equipment is required to protect the new distribution circuit from electrical surges and will look similar to other equipment already installed at the substation.

Fence changes

No changes to the existing perimeter fence are anticipated as a part of this project. A small portion of fence within the substation will need to be added to safely enclose the new equipment.

Proposed schedule

In March 2016, EPCOR will apply to the Alberta utilities Commission (AUC) for the approval to add the new current-limiting equipment. If approved, we plan to install the new equipment in the spring or summer of 2016.

Construction Details

​What to expect during construction


You can expect to see activity that is typical to construction, including company/contractor vehicles and equipment in your area. Some typical construction activities that you may see will include cranes, flatbed trucks and other equipment involved in installing the current limiting electrical equipment. All of these construction activities will occur within the Dome substation boundary.

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 receive 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.


Once construction commences we anticipate that it will take approximately four weeks to complete the project.

Road closures

No public road closures from this project are expected.

Power supply

We do not anticipate any power service interruptions from this work. If a planned power service interruption is required to complete a portion of the work, we will notify you in advance.

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.
