Canada produced 44.7 million megawatt hours (MWh) of electricity in September, equalling levels generated in September 2013. Increased electrical power generation from Ontario and Alberta was offset by declines in British Columbia, Quebec as well as Newfoundland and Labrador. Demand for electricity across the country edged down 0.6% to 40.0 million MWh. This decline, combined with flat generation levels, resulted in a 6.1% uptick in exports to the United States. Imports from the United States increased 9.1% to 0.7 million MWh as British Columbia supplemented lower generation levels.

Buoyed by gains in nuclear steam and hydro generation, net generation in Ontario increased 5.7% from September 2013 to 12.5 million MWh. The rise in nuclear generation was attributable to fewer maintenance days in September 2014, while hydro generation benefitted from higher inflows into the Great Lakes and above average precipitation in the Ottawa River watershed.

Alberta realized a 2.5% increase in net generation in September as output reached 5.1 million MWh. A return to service of some of the province's coal fuelled power plants, which were undergoing maintenance in September 2013, pushed steam conventional generation up 5.4% on a year-over-year basis to 3.8 million MWh.

In British Columbia, electricity generation in the province fell 5.3% to 4.5 million MWh on lower hydro production. Lower hydro generation was also behind overall production declines in Quebec (-1.6%) and Newfoundland and Labrador (-9.3%).

  Note to readers

The purpose of this report is to produce a consistent monthly indicator of the supply of electricity in Canada, a key input in the calculation of monthly gross domestic product.

Total net electricity generation for Canada, the provinces and the territories combines all of the electricity generated from sources, including hydro, steam, nuclear, internal combustion, wind, solar and tidal.

Total available electricity is the total electricity generation, minus deliveries, plus receipts of electricity.

All data on imports and exports are provided directly by the National Energy Board.

Data for September 2013 and for June, July and August 2014 have been revised.
