Construction Overview

The Keeyask Generating Station will include the following structures:

  • Seven unit Powerhouse/Service Bay complex on the north side of Gull Rapids
  • Seven bay Spillway on the south side of Gull Rapids
  • 23 Km of dykes built on the north and south sides of the reservoir
  • Dams across Gull Rapids (North Dam = 99 m/ Central Dam = 1,600 m/ South Dam = 565 m)

The General Civil Contract (GCC), the largest contract on the Keeyask Project, was awarded to BBE Hydro Constructors Limited Partnership (BBE) for $1.4 billion in March 2014. BBE is a limited partnership of Bechtel Canada Co., Barnard Construction of Canada Ltd. and EllisDon Civil Ltd. Work covered by the Keeyask GCC includes:

  • Rock excavation;
  • Concrete for the powerhouse and spillway;
  • Earth structures;
  • Electrical and mechanical work; and
  • Construction and removal of temporary cofferdams needed to manage river flows during construction.

The Keeyask Transmission Project is occurring in parallel to construction of the Generating Station and is owned and managed by Manitoba Hydro.  The Keeyask Transmission Project provides the transmission and station facilities necessary to integrate the Keeyask Generating Station into the Manitoba Hydro 138kV transmission network. The main components include:

  • Three Generation Outlet Transmission (GOT) Lines;
  • Four unit transmission lines;
  • A new Keeyask switching station; and
  • Upgrades to the Radisson Converter Station.
  • A construction power station and transmission lines are also required to provide the Keeyask construction site with a permanent, reliable power source during construction.

Construction Progress

Since the start of in-stream construction activities on July 16th, 2014, the Phase 1 temporary river management structures were constructed, allowing for the permanent structures to be constructed in the dry. Behind the Spillway and Powerhouse cofferdams, rock excavation for the Spillway and Powerhouse continued throughout the winter 2015/2016. The Spillway excavation was completed in early 2016 and Powerhouse excavation is approximately 97% complete. Preparations for major concrete work for the Powerhouse and Spillway continue. The 2016 construction season will be the first of two peak construction seasons.

By the end of March 2016, two of the five tower cranes required to construct the Keeyask Generating Station were erected at site. Foundation work and concrete leveling slabs were poured for the Powerhouse, Intake and Spillway. A solid, level surface is required before major concrete placements can begin in April/May.
