The 500-kilovolt direct current line, and its associated converter stations and facilities, extends from the Gibbons area northeast of Edmonton to an area near Brooks in southeast Alberta.
It adds additional capacity to Alberta's existing electricity transmission system.
In developing the application, ATCO Electric conducted an extensive public engagement process that included information campaigns, open houses and thousands of individual meetings with landowners.
ATCO says the information gained through the process was instrumental in defining the preferred and alternate routes submitted by ATCO Electric and, ultimately, the route approved by the AUC.
"I want to extend my thanks to the landowners that participated in the process," said ATCO president Sett Policicchio.
"We look forward to continuing to work together with these landowners and the communities of eastern Alberta as we begin to build this critically important piece of infrastructure for Alberta."
When complete, the Eastern Alberta Transmission Line will reinforce the reliability, increase the capacity and improve the efficiency of the Alberta grid.
