The Alberta Electric System Operator (AESO) applies to the Alberta Utilities Commission for approval of the ISO tariff under section 30 of the Electric Utilities Act. The tariff sets out the rates to be charged for, and terms and conditions that apply to, system access service provided by the AESO.
The AESO typically submits a comprehensive tariff application for approval every 2-3 years. The AESO may also file tariff updates, deferral account reconciliations, and other applications on specific aspects of the tariff.
The tariff section of the AESO website includes the current ISO tariff, tariff and related applications, and information on tariff-related consultation conducted by the AESO.
