Bechtel’s work on one of the largest hydroelectric projects in North America today harnesses the power of one of Canada’s great river systems
In 2014, the Bechtel-led BBE Hydro Constructors Limited Partnership began laying the groundwork for this new 695-megawatt powerhouse. As the centerpiece of the Keeyask Generation and Infrastructure Project, its seven turbine units will provide enough renewable energy to power 400,000 homes.
BBE is formed of Bechtel Canada in partnership with Montana-based Barnard Construction Company and Canadian contractor EllisDon. The Keeyask project involves massive cast-in-place concrete structures—chiefly a spillway and the powerhouse structure—totaling more than 345,000 cubic yards (330,000 cubic meters).
BBE’s work also includes about 1.4 miles (2.2 kilometers) of earth-filled dams and 14 miles (23 kilometers) of earthen dikes. The consortium is currently constructing cofferdams that will be pumped out to create dry work areas for the powerhouse, the spillway, and other structures.
