Ten companies submitted bids totalling 6,628MW, and making up 54 different projects, by the 5 November deadline for the government-owned utility's RFP.
The list includes prominent players in the Quebec market, such as EDF EN, Innergex, Invenergy, Kruger Energy and Boralex, as well as newcomers like Pattern Energy, which has built a significant wind power base next door in Ontario.
EDF EN, which already has more than 1GW of contracted projects in Quebec, has the most at stake in the RFP, with 17 bids totalling nearly 2.8GW.
The utility says it will evaluate the bids and announce the winners "as soon as possible".
Hydro-Quebec is seeking 100MW of wind to come online by 1 December 2016 and 350MW to be operating a year later. A total of 300MW must be located in the Gaspésie-Îles-de-la Madeleine and Lower St Lawrence regions, while the remaining 150MW can be anywhere in the province.
Projects have to meet a 60% local content threshold. Hydro-Quebec did not reveal the turbines bidders plan to use. GE, Senvion and Enercon supplied turbines in previous RFPs.
