Following the deregulation of the Alberta electricity market, electricity generators began selling their power to the Alberta Electric Systems Operator (AESO). This concept is commonly referred to as an "Energy Only Market," and is the current practice in Alberta. For more information, download a report on the “State of the Market.”
A number of new facilities have been built since 2000, and interconnections between Alberta and British Columbia, Saskatchewan, and Montana are essential in meeting the electricity demands in Alberta. Approximately 2% of the province's electrical requirements are currently supplied under import agreements.
