About the Proposal

Projects that were undergoing a comprehensive study at the time the provisions of the Canadian Environmental Assessment Act, 2012 came into force will continue to follow the requirements of the former Act. Under the former Act, the Canadian Environmental Assessment Agency is responsible for conducting the comprehensive study of this project.

The Keeyask Generation Project consists of a 695-megawatt hydroelectric generating station at Gull Rapids (Keeyask) located on the lower Nelson River and associated transmission lines, approximately 180 kilometres northeast of Thompson, Manitoba. The project, as constructed and operated by the Keeyask Hydropower Limited Partnership, would consist of a powerhouse complex, a spillway, dams, dykes, access roads, borrow sources, a work camp, and supporting infrastructure. A 93 square kilometre reservoir would be created upstream of the principal structures, consisting of approximately 45 square kilometres of newly inundated lands. A transmission line would be developed, owned, and operated by Manitoba Hydro to provide construction power to the project site. Manitoba Hydro would also build three new transmission lines to transmit electricity to an existing converter station for use in Manitoba and export markets.
