• Construct 240/500-kilovolt (kV) Heartland 12S substation to be located in the northeast quarter of Section 20, Township 56, Range 22, west of the Fourth Meridian;

• Construct 500- kV double-circuit transmission line 1206L/1212L connecting the 500-kV system on the south side of Edmonton to the proposed Heartland 12S substation; and

• Construct 240-kV double-circuit transmission line 1054L/1061L connecting the 240-kV system in the area to proposed Heartland 12S substation.

The application identifies the proposed Heartland 12S substation, a preferred route and an alternate route for a proposed 500-kV double-circuit transmission line 1206L/1212 along with several local alternate route sections for both the preferred and alternate routes. The application further identifies a preferred route and two alternate routes for proposed 240-kV double-circuit transmission line 1054L/1061L.

The preferred 500-kV route would be a joint project by the applicants whereas the alternate 500-kV route would be strictly an AltaLink project. Transmission line 1054L/1061L and Heartland 12S substation would be AltaLink projects.
