The Manitoba government announced April 17, 2008 Manitoba Hydro reached a tentative deal to provide up to 500 megawatts of power to the Wisconsin Public Service over 15 years, starting in 2018.
The $2 billion deal would require construction of Conawapa, Keeyask and Wuskwatim dams as well as the BiPole III transmission line and a 60 km transmission line between Canada and the United States.
Manitoba and Wisconsin will require regulatory approvals regarding the power sale and construction of dams and transmission lines, including environmental licenses that involve public review. Canada's National Energy Board reviews such power sales. In Canada federal environmental assessment and permits are also required for hydro projects.
