Bryson generating station

Bryson generating station was built in 1924 and 1925. It is located on the Rivière des Outaouais (Ottawa River), in Bryson, in the Grand Calumet channel. It is a run-of-river generating station with an installed capacity of 56 megawatts (MW).

To ensure the continued operation of the generating station, Hydro-Québec is planning to replace its three generating units and two decks (concrete slabs on either side of generating station).

Technical and environmental studies

Hydro-Québec is currently conducting detailed technical and environmental studies to determine the exact features of the project, become thoroughly familiar with the host environment, identify the environmental impacts and suggest appropriate mitigation measures.

According to the information we have to date, the main environmental and social considerations related to the project are the following:

  • Fish habitat
  • Presence of special-status plant and animal species
  • Truck traffic and its impact on the quality of life of neighboring residents.

Public participation

Hydro-Québec has implemented a public participation and consultation process.

The project team will thus be able to take into account the concerns of the community and its leaders so as to best adapt the project to local realities.
