Our extensive supply portfolio and the heritage pool of electricity enable us to meet capacity and energy demand. We currently have 75 contracts, ranging from 15 to 25 years, for deliveries of electricity generated by a variety of sources, and we’ve also signed a number of other agreements to secure our supply.

  1. Overall total and sum of subtotals may differ due to rounding.
  2. Includes purchases from Churchill Falls (Labrador) Corporation Limited and independent power producers, including McCormick generating station, in which Hydro-Québec holds a 60% interest.

These figures include renewable energy certificates for the output of Hydro-Québec Production’s generating stations that were sold to third parties. They exclude purchases of wind, hydraulic and biogas energy for which certificates were sold to third parties.

Wind power

We buy wind power from independent producers and feed it reliably into our grid.


Biomass involves burning residual waste (forest, agrifood and urban biomass) to produce heat and generate electricity. It is a cost-effective option in regions where industrial activities produce a large quantity of organic waste.


This energy, which we buy from independent producers, is generated from the biogas released during decomposition of organic matter.

Small hydro

We buy power from independent producers operating small hydropower plants.


We buy the surplus power of customers who generate their own electricity using renewable energy sources. Conversely, if they do not generate enough power for their needs, they can draw electricity from our grid and benefit from reliable power supply.
