Hydro-Quebec believes it has enough electricity for winter peak demand

Hydro-Québec’s initiatives to help consumers lower their bills could also strengthen the Crown corporation’s ability to manage periods of extreme cold, when water levels in its reservoirs are low.

The Crown corporation believes that the popularity of apps such as Hilo will give it greater flexibility during the winter peak period, according to a recent report by the North American Electric Reliability Corp (NERC).

The utility estimates that its efforts to manage demand have freed up an additional 450 megawatts (MW) compared to last year, according to the document from NERC, the organization that oversees the security of the North American power grid.

This additional flexibility is welcome, as Hydro-Quebec has less water in its reservoirs due to dry weather. Compared to last year, the amount of guaranteed power that the Crown corporation can supply has decreased by 89 MW.

The scenario presented to NERC suggests that Hydro-Quebec would be able to meet demand during winter peaks, i.e., the coldest days of winter.
