Keeyask Generating Station
Manitoba, Canada
The Keeyask Generating Station in Manitoba, Canada will be a 695-megawatt hydroelectric generating station providing clean, renewable energy. An average of 4,400 gigawatt hours of electricity each year will be supplied to both Canada and to the United States.
The facility will include a powerhouse/service bay complex on the north side. The Seven Bay Spillway is located on the south side, with 1.5km between the two sets of structures.
Challenge:
- The remote location, approximately 725 km north of Winnipeg on the lower Nelson River, makes getting material and support to the site challenging.
- Amount of equipment required at the same time due to the size of the project.
- Complex 3D design of the draft tube formwork.
Solution:
- Doka provided two field service technicians and one site engineer to stay at camp on a 21 day-in/7 day-out rotation.
- Doka developed a custom D22 bracket that had an adjustable leg to accommodate different rock elevations.
- Five standard Top 50 panels were also used to minimize the amount of custom panels and increase reuse rates.
