The Canadian Environmental Assessment Agency is taking comment until Dec. 21 on the potential environmental effects of the Keeyask Generation Project, a 695-MW hydro development, and the proposed measures to prevent or mitigate those effects.
Keeyask Hydropower Limited Partnership proposes the construction, operation and decommissioning of the project, a 695-MW hydroelectric generating station located on the lower Nelson River, approximately 180 kilometers northeast of Thompson, Manitoba. The project includes a powerhouse complex, spillway, dams, dykes, reservoir, and supporting infrastructure.
Keeyask Hydropower is a venture of Manitoba Hydro and four Cree Nations. This project would be in addition to five existing hydropower facilities on the Nelson River that already supply over 70% of Manitoba Hydro’s power. This new project, if approved, would go into construction in 2014 and produce first power in 2019.
The federal environmental assessment also considers a proposal by Manitoba Hydro for a 22-kilometer transmission line to provide construction power to the project and three 35-kilometer-long transmission lines within a single corridor to transmit electricity from the Keeyask Generation Project to the existing Radisson Converter Station near Gillam, Manitoba.
Following the comment period, the agency will prepare a Comprehensive Study Report, describing its conclusions on the environmental effects, the proposed mitigation measures and the significance of any remaining adverse environmental effects. A public comment period on the Comprehensive Study Report will be announced at a later date.
