Overview

​The independent system operator (ISO), operating as the Alberta Electric System Operator (AESO), has applied for approval from the Alberta Utilities Commission of the 2018 ISO tariff. The ISO tariff sets out the rates to be charged for, and the terms and conditions that apply to, each class of system access service provided by the AESO.

Based on preliminary estimates provided by the AESO, the 2018 ISO tariff revenue requirement would decrease by approximately 1.3 per cent as compared to the 2017 ISO tariff revenue requirement forecast that was approved by the Commission in Decision 22093-D02-2017.

General information on the ISO tariff can be found on the transmission rates page.
