OVERVIEW

The City of Calgary (The City) is proceeding with its Green Line Light Rail Transit (LRT) project, which would impact existing electrical infrastructure owned and operated by ENMAX Power Corporation (ENMAX Power) in downtown Calgary. At the City’s request, ENMAX has evaluated the relocation of portions of its 138 kilovolt (kV) transmission lines (2.82L and 2.83L) in the Victoria Park area (the Project). The Project would also address conflicts with other proposed City of Calgary infrastructure projects at certain locations along the existing lines. 

The Project requires the removal of an existing overhead portion of 2.83L which runs east from 6 Street SE, along and across the Elbow River and the Bow River, connecting at transmission structure 2.83-70 (as shown in the Newsletter map) near the Calgary Zoo. That portion of 2.83L will be relocated alongside the existing 2.82L, that runs south along 6 Street SE, the Elbow River and 25 Avenue SE in a double circuit alignment that transitions from underground to overhead at transmission structures 2.82-8 and 2.83-8A (as shown in the Newsletter map). The Project also involves relocating the overhead double circuit portion of 2.82/2.83L currently located along 10 Avenue SE to an underground double circuit 2.82/2.83L in 12 Avenue SE (both between 6 Street SE and Macleod Trail SE) and 3 Street SE.

To construct the underground portion of the Project, ENMAX Power is proposing to excavate (open trench) at certain locations along 10 Avenue SE, 3 Street SE and 12 Avenue SE to install a new duct bank which will house 2.82/2.83L. That new duct bank will connect with an existing duct bank that currently houses 2.82L and runs from the intersection of 12 Avenue SE and 6 Street SE to the location of transmission structures 2.82-8 and 2.83-8A (as shown in the Newsletter map). ENMAX Power is proposing to install the 2.83L cable within this existing duct bank to run alongside the existing 2.82L. New maintenance holes will be installed at various locations to allow access to the underground cables. 

At transmission structures 2.82-8 and 2.83-8A, the 2.82/2.83L cables will transition to overhead double circuit lines and follow the existing overhead 2.82L alignment along 25 Avenue SE toward ENMAX No. 2 Substation. ENMAX Power is proposing to replace the existing single circuit structures along this portion of the route with double circuit steel self-supporting monopoles which will be shared by 2.82L and 2.83L.​​




PROJECT IMPACTS AND MITIGATION MEASURES​

ENMAX Power will take measures to limit potential impacts to residents and businesses in the area during the Project construction period. 


Road Closures 

ENMAX Power anticipates the need to close certain roads and lanes periodically during construction of the Project. Such closures will be detailed in a traffic management plan to be approved by The City. Construction will be completed in segments and in a manner that limits impacts to sidewalks, bike lanes and traffic.  Certain activities will be performed during low traffic times on weekdays and weekends, where possible. 

Power Outages 

There are no planned power outages impacting customers associated with Project construction. 

Access 

A construction execution plan is currently in development which will address access to commercial and residential spaces in the affected area.  Where necessary, accommodations for temporary access will be implemented and communicated to local residents and business owners to minimize potential impacts.


OPEN HOUSE​

ENMAX Power will be available at four open houses to share information, gather your feedback and address any questions or concerns you may have about the Project.
