Substation 35

​Southwest Calgary​​

Project overview

Alberta Transportation has started planning for the construction of the SW portion of the road that will complete the Calgary Ring Road.  The completion of the Calgary Ring Road requires the relocation of several utilities that are directly impacted by the road construction.  The Province is working collaboratively with the impacted utility companies to help facilitate their planning and design.

In the preliminary phase of the road design, ENMAX No. 30 Substation located at 11111-37 Street SW on Tsuu T'ina land, was identified as being situated on the alignment of the Ring Road.  Alberta Transportation has requested ENMAX to relocate the substation, its transmission lines and distribution feeders away from the road alignment.

For service continuity purposes, ENMAX is proposing to build a new substation (No. 35) while the existing one is still in service.  The new substation will have the same capacity as the existing one.  Once construction of No. 35 Substation is complete, No. 30 Substation will be decommissioned and salvaged.
