Andritz will refurbish six of the eight units at the power station, which was originally commissioned in 1963. The other two units were already refurbished by Andritz eight years ago. The scope of work includes model testing and the replacement of six Francis turbine generator sets, including auxiliaries as well as mechanical and electrical balance of plant. The Francis runners will have a diameter of 4 meters and generate 35 MW each at a rated head of 32 m. The first unit will be dismantled in August 2019 and put back into operation in July 2020. The remaining five units will follow at a rate of one per year until 2025.
This is the biggest hydropower refurbishment contract to date for ANDRITZ in Canada.
