OVERVIEW

PROJECT DETAILS

Both the preferred route and alternate route will follow a similar alignment which involves relocating the existing 16.61L along John Laurie Boulevard NW in the Charleswood and Collingwood communities.

In the Brentwood community, both the preferred and alternate route will involve relocating the existing 16.61L away from private property to allow for necessary maintenance access. Distribution services will remain in place along the existing alignment. As a result, the height of existing poles that currently house both 16.61L and distribution wires will be shortened, while existing distribution poles that do not support 16.61L will remain unchanged.​

In the Dalhousie community, the preferred route will involve replacing the poles along the current alignment. The alternate route will involve relocating 16.61L to a new alignment, primarily within Shaganappi Trail NW and Crowchild Trail NW. On January 25, 2023, the Alberta Utilities Commission approved the preferred route: Partial Relocation Route. AUC decision 27474-D01-2023.

POTENTIAL CONSTRUCTION IMPACTS

Every effort is made to minimize the effect construction work has on daily stakeholder activities. ENMAX Power follows all applicable requirements, including standards and bylaws.

Access

• ENMAX Power does not anticipate the need to close entire roads for the construction of this Project. Lane and pathway closures will take place periodically during construction and will be detailed in a traffic management plan to be approved by The City of Calgary. Construction will be done in segments and will be limited to low traffic times on both weekdays and weekends, where possible. 
  

• Private property access: For a portion of the alignment in the Brentwood area, access to fenced yards will be required. Access will be coordinated with any affected residences.

Vegetation Management

• Trees growing too close to overhead power lines will be trimmed to maintain safety requirements. Trees in conflict with the proposed alignment may be removed to maintain adequate clearance and allow for the safe installation of 16.61L. ENMAX Power will work with The City of Calgary’s Urban Forestry to determine the appropriate tree management plan.
  

Noise

• ENMAX Power will provide prior notice to stakeholders in the event of temporary increases in noise and/or minor vibrations during construction activities.

Power Outages

• In advance of construction, planned power outage(s) may be required to facilitate this work. If your residence is impacted, you will receive direct notification with details indicating important outage information.

 ​

TRANSMISSION STRUCTURES

The existing wood poles range in height from 9 to 20 meters. Subject to the final approved route and detailed design, the new structures will be a combination of wood poles, self-supporting steel monopoles and/or laminated wood poles. The new structures are expected to range in height from 18 to 30 meters as required to meet engineering and safety requirements.

PROPOSED SCHEDULE 

ENMAX Power has filed the Facility Application with the AUC on June 24, 2022. Subject to receiving approvals and procuring materials, construction is anticipated to occur in Q3 2023. Project construction is anticipated to take approximately three months, with an expected in-service date in Q4 2023. ENMAX Power will provide notification to impacted stakeholders in advance of Project construction. On January 25, 2023, the Alberta Utilities Commission approved the preferred route: Partial Relocation Route. AUC decision 27474-D01-2023.
