The construction of this project is staged to align with certain generation milestones.

In December 2022, the Alberta Electric System Operator (AESO) directed AltaLink to begin Stage 1 of the project as the milestone had been met to trigger that stage. 

Stage 1 involves building a new double circuit 240 kilovolt transmission line and installing new equipment at the Gaetz Substation. AltaLink’s new transmission line will be between AltaLink’s existing Gaetz Substation and ATCO Electric’s approved transmission line.
