Electricity Statistics

Electricity Supply
An important objective of electricity restructuring has been the development of a competitive generation market. Access for all power producers to Alberta's interconnected transmission grid is integral to the success of electricity generation.

Alberta's restructured electricity industry has encouraged efficiencies and allowed new generation supply to come on-line to keep pace with one of the fastest growing economies in North America.

Alberta has seen new generation capacity additions of over 7,800 megawatts (MW) since 1998.

As of August 2014, over 10,000 MW of thermal power, and over 2,600 MW of renewable power, have been proposed by industry for future development.

As of September 2014, Alberta has 14,598 MW of installed generating capacity.  Peak demand in 2013 (climatic year) was 11,139 MW – up 540 MW from 10,599 in 2012.

*Waste heat generation is a system that produces electricity from a heat source that is a by-product of an existing industrial process, the heat that would have been otherwise wasted.

*Cogen is an abbreviation for Cogeneration. Cogeneration is the concurrent production of usable forms of energy from waste heat. Industrial plants or power plants may produce excess heat, which can be used directly or used to produce electricity with a steam turbine.

*Peak demand is based on the climatic year (October to September).
**A gigawatt hour (GWh) is equal to 1,000 megawatt hours (MWh) and one MWh is equal to 1,000 kilowatt hours (KWh).  For context the average household in Alberta consumes 7,200 kWh (0.7 MWh) of electricity per year. AESO also offers real time pricing reportsexternal link icon
