Bechtel completed the Hanna Region Transmission Development (HRTD) project on schedule and under budget. The project to expand and upgrade ATCO Electric’s electrical transmission system and infrastructure in Alberta included stringing 219 miles of 240 kV and 144 kV transmission lines, constructing more than 1,200 new transmission towers, and building six new substations and upgrading twelve substations.
About 60 percent of the area where the transmission line was built passed through protected pasture, native grasses and wetlands that are also popular wildlife breeding grounds.
To minimize the impact, the project team used a mobile app to ensure that the field team had customized information about accessing land parcels and environmental regulations.
The company is now supporting ATCO Electric’s Eastern Alberta Transmission Line project. Bechtel will construct about 300 miles of 500-kV high voltage direct current transmission line that runs from the Gibbons-Redwater area northeast of Edmonton to the Brooks area southeast of Calgary.
