Edmonton, AB — ABB’s power and automation technology group has won a $7.5-million bid from Atco Electric to provide the equipment for the construction of a power transmission line that will run from Fort McMurray to Edmonton in Alberta. It is the first major transmission infrastructure project to be undertaken in the province in the past 20 years.

The ATCO Electric transmission project involves the construction of a new 350-km, 240-kV transmission line, along with one 300-kV switching station and two 240-kV to 144-kV substations.

Fort McMurray is the site of one of the largest oil reserves and ongoing engineering projects in the world. The industry involved in the recovery of oil in the region has a significant surplus of generation that can be used in other areas of the province. The new line will serve to move the excess power to markets in central and southern Alberta, while enhancing the reliability of the transmission system in Alberta.

According to the terms of the ATCO contract, ABB’s participation in the project calls for the provision of:


45 -300-kV current transformers
9 -145-kV current transformers
2 -200-MVA 260/144-kV autotransformers
16 -300-kV breakers
3 -170-kV breakers.

A member of the Atco Group of companies (, Atco Electric is an investor-owned utility supplying electrical energy to customers throughout northern and east-central Alberta. ABB in Canada employs 2,100 people at 25 different facilities from coast to coast.
