Our thermal generating stations supply the communities in Nunavik, Haute-Mauricie, Basse-Côte-Nord, Île d’Anticosti and Îles de la Madeleine, which are too remote to be connected to the main grid. These regions are home to a total of some 35,000 inhabitants in 30 communities that include Atikamekw, Cree, Innu and Inuit populations. They are supplied by 22 diesel-fired thermal generating stations, one oil-fired thermal plant (Îles-de-la-Madeleine) and one hydropower plant (Lac-Robertson). The main grid is supplied by Bécancour thermal generating station during peak periods only.

Gentilly-2 nuclear generating station ceased operations on December 28, 2012. The main steps of its decommissioning are now complete, and the facility was rendered dormant in January 2015. Hydro-Québec is finalizing the facility’s transition into the first phase of a safe state of storage. To achieve the second phase in 2021, we will transfer the irradiated fuel from the pool to the dry storage area, where two new modules will be built.

Dismantling of Gentilly-2 nuclear generating station

This figure illustrates the phases in the dismantling of the nuclear generating station from 2013 to 2066:

  • 2013 to 2014 Defueling the reactor; draining the heavy water and light water.
  • 2015 to 2059: Transferring and storing the irradiated fuel in storage modules after it has spent seven years in the cooling pool, maintaining the systems still being used, constantly monitoring the site.
  • 2059 to 2064: Dismantling the generating station.
  • 2065 to 2066: Restoring the site.
