Overview
The Alberta Electric System Operator (AESO) has identified the need for upgrades and additions to the electric transmission system in east Calgary. The transmission reinforcements will meet a steady increase in demand for additional power and improve reliability in the area. This project will also connect the Calgary area to locally generated power from the proposed Shepard Energy Centre.


This
project involves:

AltaLink and ENMAX Power are working together as the proposed project includes work in the operating areas of both companies.

AltaLink

  • Work at four existing substations and transmission line connections in the immediate area surrounding the substations:
    • AltaLink Janet substation located at Garden Road and 50 Avenue SE
    • AltaLink East Calgary substation located at 3115 – 9 Street SE
  • A voltage increase on an existing AltaLink transmission line between the Janet and East Calgary substations.
  • New transmission line infrastructure to connect existing adjacent transmission lines to the proposed Shepard switching station.


ENMAX Power

  • Work at four existing substations and transmission line connections in the immediate area surrounding the substations:
    • ENMAX No. 23 substation located at 2412 – 50 Avenue SE
    • ENMAX No. 2 substation located at 3120 – 9 Street SE
  • A new switching station to be built by ENMAX Power to connect the proposed Shepard Energy Centre (owned by ENMAX Energy) to the Calgary area grid.
