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 addition of over 9,000 megawatt (MW) since 1998. As of August 2015, over 7,700 MW of Thermal and others, and over 2,400 MW of Renewable power have been proposed by industry for future development. At present, Alberta has 16,242 MW of installed generating capacity.  Peak demand in 2014 climatic year (October 2014-March 2015) was the all-time high 11,229 MW - up 90 MW from 11,139 MW in 2013.

** 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 (7.2 MWh) of electricity per year. AESO also offers real time pricing reportsexternal link icon
