Project Details
We're replacing one motorized disconnect switch as well as one terminal structure within the Petrolia substation (3007 142 Street). Construction will take place within the fenced substation. The disconnect switch is being replaced as part of a life cycle replacement program. A new terminal structure will support a heavier transmission line that AltaLink will be installng between the Wabamun area and the Petrolia substation.
The substation is a part of the electrical system that connects two or more power lines. It converts electricity from high-voltage power lines (transmission lines) to lower voltages that can be distributed to homes and businesses in the area.
Timeline
The project has been approved by the Alberta Utilities Commission (AUC) and the work is anticipated to be completed by early 2013.
What to expect during construction
Visual
All proposed work will be completed on EPCOR property within the Petrolia substation. You can expect to see company vehicles and equipment entering and exiting the substation. The new terminal structure will be the same height and width as the current structure; however, the material and design will change slightly to support the heavier line.
Noise
Noise levels are not expected to exceed the allowable levels set by the City of Edmonton’s Community Standards Bylaw for Noise Control. Should it be necessary to temporarily exceed acceptable noise levels, we'll apply to the City for a noise permit and notify area residents of the proposed disruption.
Road Closures
No road closures are expected.
Power Supply
We don't anticipate any power service interruptions from this proposed work. You will continue to receive safe and reliable electricity.
