Situated on the south bank of the Pelly River, Ross River is a small community in east-central Yukon. Cyclical spring thaws and ice jams caused Pelly River to flood into Ross River’s low-lying areas. The floods contributed to higher road maintenance costs, broken road BST surfacing, and surface water pooling within ditches and low areas. Local First Nation and territorial governments requested a road network re-design and re-construction to resolve these long-standing roadwork and drainage issues.
This greenfield project involved stripping topsoil and constructing a substation pad. This included installing 336 screw piles, 4 breaker pads, 2 transformer pads with Sorbweb oil containment, and constructing the substation access road. Finally, the site was remediated by placing topsoil and grass seeding.
Located northwest of Medicine Hat, Bowmanton 244S is a substation that switches from 138 kV to 240 kV. CAP constructed the 240-kV side of the substation. The work for the concrete foundations included the installation of 170 concrete piles, 9 concrete circuit breaker pads, 2 concrete transformer pads, and 2 oil containment systems. Survey was required for layout, checks, and as-builts.
Together with our partners, CAP installed 263 self-supporting and guyed steel lattice towers for this project. This transmission line spans 95 km of isolated mountainous terrain. It extends from the Bob Quinn airstrip, to Imperial Metals’ Red Chris Mine and the surrounding communities at Tatogga Lake.
The NE Loop project responded to the need for a comprehensive transmission circuit to supply the Husky Oil Sands project. It eventually brought power to the Kearl Oil Sands projects. To develop the NE Loop, over 100 km of a single circuit 240-kV transmission line was constructed. This was completed with 5 greenfield substations and the retrofit of 1 brownfield substation.
