ISO Rules – Revenue Metering System Requirements

In this decision, the AUC approved the application from the Alberta Electric System Operator (“AESO”) requesting new Section 502.10 of the Independent System Operator (“ISO”) Rules, Revenue Metering System Technical and Operating requirements, and the associated terms and definitions.


The AESO developed the final proposed new Section 502.10 and the associated terms and definitions that set out the requirements for the installation, operation, and maintenance of revenue metering systems in collaboration with stakeholders.

AUC Findings

Noting the absence of opposition to the application, and as no evidence to the contrary was submitted, the AUC was satisfied, based on the AESO’s explanations, that the proposed amendments to Section 502.10 are not technically deficient; support the fair, efficient, and openly competitive operation of the market; and are in the public interest.
