SOUTHWEST CALGARY RING ROAD (SWCRR) PROPOSED 138 KV TRANSMISSION LINE RELOCATION
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 SWCRR 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.
The road design for the SWCRR conflicts with existing transmission infrastructure. Alberta Transportation has requested ENMAX Power (ENMAX) to relocate its transmission lines away from the road alignment and into the new Power Line Component of the newly established Transportation Utility Corridor (TUC) along the SWCRR. This land was transferred from the Tsuu T’ina Nation to the Government of Alberta to accommodate a portion of the SWCRR and TUC.
PROJECT DETAILS The project requires construction of new 138 kV transmission lines as well as the removal and salvage of existing transmission lines including: • Construction of a new 138 kV transmission line from AltaLink Substation 42S located at the intersection of Sarcee Trail and Glenmore Trail to TRANSPORTATION UTILITY CORRIDOR ENMAX Substation 35 located north of 90 Avenue SW in the southwest (TUC) corner of Glenmore Park In the mid-1970s, the Government of Alberta • Construction of a new 138 kV transmission line from ENMAX Substation established Restricted Development Areas (RDAs) 35 to ENMAX Substation 6 located at 16300 – 37 Street SW around Calgary. The lands included in these RDAs were designated to accommodate linear transportation and • Removal and salvage of an existing 138 kV line between AltaLink Substation utility facilities. These uses include ring roads (and 42S and ENMAX Substation 30 located at 11111 – 37 Street SW and a associated interchanges), stormwater management section of transmission line south of ENMAX Substation 30 once ENMAX facilities, petroleum pipelines, power transmission Substation 35 and the new proposed transmission lines are energized. lines and municipal regional water, sanitary and storm sewer lines.
