Hydro-Québec
Robert-Bourassa generating station is one of the crown jewels
in Hydro-Québec’s generating fleet. With an installed capacity
of 5,616 MW, it is the most powerful generating facility in
Québec. Its longevity is essential to ensuring the long-term
supply of reliable power in Québec. This project includes
the rehabilitation of eight of the sixteen generating units of
the Robert-Bourassa generating station, as well as the speed
governors, static excitation systems and cooling systems in all
sixteen units. The DEW generating units (made by Dominion
Engineering Works) will be the ones rehabilitated, as they
show the most signs of wear. This work will allow HydroQuébec. to optimize its facilities and adequately secure
Québec’s energy future. Project completion is targeted for
2022, which will see such milestones as the final assembly
of the seventh generating unit (out of a total of eight to be
replaced).

Faro Mine is a former open-pit lead-zinc mine, one of the largest of its kind in the world at approximately 25 sq. km. It is lo-
cated in south-central Yukon on the traditional territory of the
Kaska Nations, near the town of Faro. Abandoned in 1998, resource extraction led to 70 million tonnes of tailings and 320
million tonnes of waste rock. Care and maintenance work since
then has helped to ensure water quality so that environmental
standards are met.
In 2020, the construction of the North Fork Rose Creek realignment and associated contact water collection system was
completed. In 2021 additional urgent works to collect contact
water and increase water treatment capacity have been completed. Active remediation is expected to begin in 2025 following the successful completion of the Yukon environmental and
socio-economic assessment process, and receipt of a water licence from the Yukon Water Board. Remediation is expected to
take about 15 years to complete, followed by ongoing operations
and monitoring.
