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.
Over 5,300 megawatts (MW) of new generation have been added to the Alberta power supply since 1998.
Over 9,400 MW of Thermal power, and over 14,000 MW of renewable power, have been proposed by industry for future development.
At present, Alberta has more than 12,700 MW of installed generating capacity. Peak demand in 2008 (climatic year) was 9,806 – up from 9,701 MW in 2007.
