Mr. Bertrand runs approximately 50 ASICs in a warehouse on the outskirts of Montreal. Each unit consumes approximately 90¢ CAD (roughly 70¢ USD) daily, yet can produce a revenue of approximately $600 CAD ($470 USD) monthly. The inexpensive power costs are attributed to an abundance of hydropower in the province, which, Mr. Bertrand claims, is attracting the interest of major mining companies from China and Iceland.
Hydro-Quebec, a state-owned enterprise based in Montreal, manages the distribution of power throughout Quebec. It is estimated that more than 40 percent of Canada’s water resources are located in the province, resulting in Hydro-Quebec comprising the fourth largest producer of hydropower in the world. Although the average price of residential power in Quebec is 5.82¢ CAD (4.56¢ USD) per kilowatt-hour (kWh), Hydro-Quebec recently announced that it will introduce an ‘Industrial Revitalization Rate‘ from April 1st, 2018. Once in effect, the new rate will provide electricity to companies requiring “at least 500 [kilowatts] in additional demand” for 3.30¢ CAD (2.58¢ USD).
