Wind farms belong to private producers from whom we buy the energy output. The various contracts were awarded following public calls for tenders. The Québec government decided to support the development of wind power, essentially for regional development reasons. Hydro-Québec respects this choice. Wind power is clean and renewable.
You can consult the list of producers under contract.
With respect to the environment, all wind farms must obtain required environmental authorizations from governmental authorities before beginning construction.
