From 1999 to 2013, Hatch teamed with Manitoba Hydro and its partner First Nations to develop preliminary designs for the 695 MW Keeyask Generating Station to be constructed in northern Manitoba. The designs were imperative for verifying the economics and to advance the project into the licensing process. The work included field explorations, design development, cost estimating and environmental assessment support. The studies utilized state-of-the-art computer modelling to design structures, design environmental mitigations measures and assess environment impacts. The generating station is designed to minimize flooding and to limit the fluctuation of forebay water levels during operation.
