    Colinton 159S Substation Upgrade

    FortisAlberta Inc. (FortisAlberta) has applied to the Alberta Electric System Operator for transmission system access to improve reliability in the Athabasca / Lac La Biche area. FortisAlberta’s request can be met by upgrading the existing Colinton 159S substation, including replacing a 138/25 kV transformer with one of higher capacity, and adding four 25 kV breakers and associated equipment.
