    Turbo Balzac 391S Substation Modification and Chestermere 419S Substation

    FortisAlberta Inc. (FortisAlberta) has applied to the Alberta Electric System Operator (AESO) for transmission system access to reliably supply growing demand for electricity in the Chestermere and Balzac areas. FortisAlberta’s request can be met by the following solution:

    • Construct the Chestermere 419S substation with two 138 kV transformers, three 138 kV circuit breakers, and associated equipment; 
    • Add two 138 kV transmission lines to connect the Chestermere 419S substation to the transmission system; and
    • Modify the Turbo Balzac 391S substation by adding a 25 kV circuit breaker and associated equipment.
