New Transmission Line in Southeast Calgary

Electricity consumption in the Calgary area is forecast to increase by approximately 26 per cent in the next decade. The Alberta Electric System Operator (AESO) has determined the existing transmission system in South Calgary will become overloaded as the demand for power rises.  This could reduce the reliability of our power supply and the increase the likelihood of power outages in the future.

AESO has identified the need to add a new transmission line in order to prevent transmission line overloads in the South Calgary Area.  To meet this need, ENMAX has identified two viable transmission routes – a preferred and an alternate.  The total length of the proposed transmission line to be constructed is approximately 14-22 kilometres depending upon the approved route.

During the process of determining possible route options, ENMAX considers takes into account the following factors in order to select a route with the lowest overall impact:

  • Agriculture
  • Residential
  • Environmental
  • Electrical
  • Cost
  • Visual
  • Special constraints

ENMAX Map

The preferred route:

  • Is approximately 14 km and is the shorter of the two routes
  • Is the lower cost option
  • Utilizes the existing transportation utility corridor
  • Route runs from 88 Street west along Highway 22X to Macleod Trail and then north on Macleod Trail to ENMAX Substation No. 41.

The alternate route:

  • Has fewer residences, however, it is zones for future development
  • Is the longer of the two routes at 22 km
  • Is the more expensive option
  • Proceeds south on 88 Street to 210 Ave; west on 210 Ave, to Macleod Trail and then north to ENMAX substation No. 54 to Macleod Trail and then North to ENMAX Substation No. 41.

In terms of structure, for both the preferred and alternative routes would be self-supporting steel monopoles with a height of 18 to 24 metres and the distance between structures of 100 to 125 metres.

Proposed Project Schedule

ENMAX Power and AESO representatives will be available at open houses to share information, gather your input and address any questions or concerns you may have.
