Transmission line 398L between Provost 545S Substation and Hayter 277S Substation
AltaLink proposes to build a new 33 kilometre single-circuit 138-kV (kilovolt) transmission line, using primarily wood monopoles, and has identified two potential alternatives for the AUC to consider. Altalink has identified a route that follows Highway 899 for almost half of its length as its preferred route. The route AltaLink has identified as its alternate route (indicated by a dashed line on the map) follows some of the same paths as the preferred route, but are at times east or west of AltaLink's preferred option on a north-south direction.
Provost Substation 545S
AltaLink has applied to modify this substation located at 13-7-39-2-W4. The substation additions of one MVA transformer, two new 138-kV circuit breakers, four 25-kV circuit breakers, one new control building and associated equipment is applied for in order to accommodate the termination of Transmission Line 398L. These alterations will require an expansion of the existing substation fence.
Hayter Substation 277S
AltaLink has applied to modify this substation located at 1-17-41-1-W4 to facilitate the termination of Transmission Line 389L. The alterations will occur within the existing fenced area. Additions to this substation include two MVA transformers, three 138-kV circuit breakers, six 25-kV circuit breakers, one telecommunications tower and associated equipment.
Killarney Lake Substation 267S
AltaLink has applied to upgrade this substation within the fenced area located at 4-1-42-3-W4. The project involves adding one MVA transformer, two 138-kV circuit breakers, three 25-kV circuit breakers, three capacitor banks and associated equipment. The project also involves the replacement the existing telecommunications tower.
Transmission Line 715L is an existing transmission line between the Metiskow 648S and Provost 545S Substation.
AltaLink has applied to relocate 0.1 km of this existing 138-kV transmission line to accommodate the termination of the 389L Transmission Line at the Provost 545S Substation.
