History of sources of electricity generated in Québec
Description
All of Hydro‑Québec’s historical data on the breakdown of the sources of electricity generated in Québec according to their real or estimated power in megawatts (MW). Updated hourly, the data is collected annually and corresponds to the output of both Hydro‑Québec’s generating stations and those of other electricity suppliers that have an electricity supply contract with Hydro‑Québec.

Useful information for interpreting the data
Electricity generation data is sent hourly, on the half hour, that is, at 8:30 a.m., 9:30 a.m., etc.
With regard to solar power, our first generating stations were commissioned in the first quarter of 2021. Solar power is therefore not included as a generating source for 2019 and 2020, and only partial data is available for 2021. Only the file for 2022 contains data from a full year of electricity generation by Hydro‑Québec’s solar farms.
Energy sources
Hydroelectricity: Sum of the remotely measured output from all of Hydro‑Québec’s generating stations and the generating stations of other electricity suppliers that have a supply contract with Hydro‑Québec.
Wind power: Sum of the remotely measured output from facilities belonging to independent power producers from whom Hydro‑Québec purchases all output.
Solar power: Sum of the remotely measured output from Hydro‑Québec’s solar farms.
Other renewables: Sum of the estimated output from facilities belonging to independent power producers using different sources (biomass, biogas or hydropower), from whom Hydro‑Québec can purchase some or all of the output.
Thermal power: The remotely measured output from Bécancour thermal generating station.
Description of labels
The files can contain text data (e.g., Montréal), numerical data (e.g., 2021‑05‑21) or geometric data (e.g., 46°48'44"). They are organized based on specific labels, which correspond to categories. The labels and their descriptions are provided below.
- Date: date and time the measurement was taken
- Hydroelectric (numerical): hydroelectric output in megawatts (MW)
- Wind (numerical): wind output in megawatts (MW)
- Other (numerical): output in megawatts (MW) from facilities belonging to independent power producers using different renewable sources
- Solar (numerical): solar output in megawatts (MW)
- Thermal (numerical): thermal output in megawatts (MW)
- Total (numerical): total output in megawatts (MW)
