Bechtel announced that it has completed the Hanna Region Transmission Development (HRTD) project in south-east Alberta on schedule and under budget.
The company was selected by ATCO Electric, an Alberta-based, investor-owned electric utility company, to provide project and construction management services for the project.
The project included constructing 219 miles (353km) of 240kV and 144kV transmission lines and more than 1,200 new transmission towers.
As part of the work, Bechtel also constructed six new substations and upgraded 12 substations.
ATCO Electric Transmission Division president Sett Policicchio said the construction of the HRTD project has helped the company meet the increased demand for electricity in the Hanna region due to industrial growth in the area.
The transmission line passes through protected pasture, native grasses, and wetlands that are also popular for wildlife breeding grounds.
To minimise the impact, where the transmission line accounts for 60% of the area, the project team has developed and implemented a mobile application to ensure that the field team had customised information about accessing land parcels and environmental regulations.
Bechtel transmission business line president Toby Seay said, "The complexity of this project was in the logistics of constructing a variety of transmission-line segments over a vast geographic area, with varying site conditions.
"Despite working miles apart, the Bechtel and ATCO Electric team worked in unison to develop innovative and sustainable solutions that ensured the safe delivery of the project with minimal environmental impact."
Bechtel will now commence the construction of 300 miles (485km) of 500kV high-voltage direct current transmission line for ATCO Electric's Eastern Alberta Transmission Line project.
The transmission line will be constructed between the Gibbons and Redwater area north-east of Edmonton and the Brooks area southeast of Calgary.
