In fact, it is just the opposite! Our residential customers pay the lowest rates in North America, thanks to our hydroelectricity, a clean and renewable source of energy, and the heritage pool. In addition, Hydro-Québec maintains its commitment to limit its rate increase to inflation 2016-2017.
To answer the other part of your question, our electricity isn’t sold any cheaper on external markets. In fact, in 2014 our electricity exports generated profits of more than $800 million. You can’t compare the price you see on your bill (which covers power generation, transmission and distribution costs) with the wholesale prices offered to Québec’s neighbors (which includes only generating costs and a portion of transmission costs).
In Québec, consumers pay 7.19¢ per kWh for electricity, which includes transmission and distribution costs. This price must not be compared with the price of electricity sold on wholesale markets in the United States.
