Link to Decision Summarized

Electricity – Law

In this decision, the AUC approved the new Alberta reliability standard ADM-002-AB-1 proposed by the Alberta Electric System Operator (“AESO”) pursuant to subsection 19(4)(b) of the Transmission Regulation.


Section 103.14 of the Independent System Operator (“ISO”) Rules, Waivers and Variances, which was developed to more effectively address requests for waivers and variances related to the Division 502 ISO Rules, was approved by the AUC in Decision 24885-D01-2019. The AESO found that a similar mechanism would be useful for reliability standards. Therefore, the framework of Section 103.14 is followed in the proposed new Alberta reliability standard ADM-002-AB-1. The proposed new reliability standard allows for a waiver or variance request to be submitted and approved for any new requirement in a reliability standard that does not already have its own mechanism.

AUC Findings and Decision

Subsections 19(5) and 19(6) of the Transmission Regulation require the AUC to approve or refuse to approve each reliability standard as recommended by the AESO unless an interested person convinces the AUC that the recommendation is technically deficient, or not in the public interest. No objection indicating that the proposed new ADM-002-AB-1 is technically deficient or not in the public interest was filed.

Pursuant to subsection 19(6) of the Transmission Regulation and based on the recommendation of the ISO, the Commission approved the proposed new ADM-002-AB-1, effective April 22, 2021.
