About the Tariff
The transmission tariff is set by an Alberta Electric System Operator (AESO) application to the Alberta Utilities Commission (AUC). The prices and rates are set in a two-step process:
- The Phase I application determines the revenue requirement for the AESO. The EUB decision on this application determines the prudently incurred costs by the AESO necessary to manage the transmission system in Alberta.
- The Phase II application determines the allocation of costs between the different classes of customers for the provision of system access service by the AESO. The EUB decision on the Phase II application determines the rates charged to customers to recover the revenue requirement determined in Phase I.
