The Alberta Utilities Commission (AUC) is responsible for the development of rules regarding the role of market participants involved in electric load settlement and the development of comprehensive standards for electronic business transactions. Electric Load Settlement Rules allow for the accurate, efficient and timely communication of load settlement information among market participants.

AUC Rule 021 System Settlement Code Rules has been adopted by the AUC to set the comprehensive standards for the market participants.

The provincial government introduced legislation that separated the Alberta Energy and Utilities Board (EUB) into two separate regulatory bodies-a new Energy Resources Conservation Board and the Alberta Utilities Commission (AUC).  One of the provisions of Bill 46, the Alberta Utilities Commission Act, moved the rule-making responsibility for the Settlement System Code from the AESO to the AUC effective January 1, 2008.

The AUC has been working closely with stakeholders in resolving outstanding Settlement Issues identified in the past and new issues that were recently raised by stakeholders. The results of resolving issues might lead to AUC Rule 021 changing. The AUC mapped out an annual "Rule 021 change cycle" as follows:
