The government of Quebec is presently holding a public debate on the province's future energy policy . Encouraging new energy sources is one of the options to be examined. Wind power is considered as one of the most promising "new" sources available. The object of this communication is to determine whether wind energy can play an import ant and profitable role in th e province's electricity supply, essentially composed of hydroelectric power. Treating the output from a complex of wind farms as negative load, we specify the energy value and capacity value of this complex. The estimations are then used in a cost-benefit analysis applicable to Hydro-Quebec. We conclude that wind energy is still economically unattractive. Expected losses to the provincial corporation vary between 40-47% of the global costs of the complex for a conservative cost scenario and 18-32% f or an alternative cost scenario. However, moderate reductions in the costs of wind energy technology would be sufficient to render a well-situated wind farm economically viable.
