The Alberta Electric System Operator (AESO) has released updated details on its restructured energy market (REM) design and is now seeking feedback from industry stakeholders to help finalize it. Once the design is finalized, the AESO will work with industry to develop the necessary independent system operator (ISO) rules and define system requirements for implementation.
In Proceedings 29093 and 29940, the Alberta Utilities Commission (AUC) issued its final decision on the Alberta Electric System Operator’s (AESO) application for amendments and additions to the Independent System Operator (ISO) rules, known collectively as the Interim Market Power Mitigation Rules.
The Alberta Electric System Operator (AESO) held a design finalization session on April 10, 2025, after unexpectedly cancelling the remaining two weeks of its originally scheduled consultation process. This session followed significant design changes to the Restructured Energy Market (REM), including the removal of some previously proposed markets and revisions to others.
In Decision 28989-D01-2024-002, The Alberta Utilities Commission (AUC or Commission) released its reasons for approving the Alberta Electric System Operator (AESO) application to amend the Demand Opportunity Service Rate ( Rate DOS) back in 2024.
In proceeding 29093 market participants submit arguments and reply arguments in support of their request to the Alberta Utilities Commission (The Commission or AUC) that the AUC not approve Section 206.2 of the new Rules and direct the Alberta Electric System Operator (AESO) to amend this section.
In proceeding 29109, ATCO Electric and the Alberta Utilities Commission Enforcement Staff (Enforcement Staff) submit a settlement agreement to the Alberta Utilities Commission (the Commission) regarding two issues of misrepresented financials that ATCO Electric self-reported to Enforcement Staff; an additional error was also discovered in ATCO Electric’s revenue requirement during the subsequent investigation of the issues. The party’s have requested that the Commission accept the settlement of an administrative penalty of $3 million, a refund of $4 million to customers, and payment of Enforcement Staff’s external legal counsel related to this proceeding.[1]
The Alberta Electric System Operator (AESO) recently held a stakeholder session to provide an update on the restructured energy market plan and to inform stakeholders of its consultation plan going forward. Over 100 stakeholders from the industry attended the virtual session.
Back in March, the Alberta Minister of Affordability and Utilities (the Minister), requested the AESO to work with industry stakeholders to develop a restructured energy market plan. Since then, the AESO received further direction from the Minister to implement a day-ahead energy market, continue mitigating market power, maintain a uniform energy price, review the current price cap and floor, and to develop the remaining elements of the energy market plan.
In proceeding 29093, the Alberta Electric System Operator (AESO) applied for the approval of new and amended market mitigation independent system operator (ISO) rules to be in effect by July 1, 2024. On June 19, 2024, the Alberta Utilities Commission (the Commission) approved the rules on an interim basis and subsequently initiated a proceeding to consider approving these rules on a final basis. Nine intervenors submit their intentions to participate in the proceeding along with their written statements.[1]
In Proceeding 28989, The Alberta Electric System Operator (AESO) responds to information requests (IR’s) filed by intervenors and the Alberta Utilities Commission (the Commission or AUC) regarding its application to update its Rate Demand Opportunity Service (DOS). With these updates, the AESO aims to make the Rate DOS technology agnostic, simpler, and easier to administer.
On June 11, 2024, the Alberta Electric System Operator (AESO) held its second information session concerning the interim market power mitigation regulations that go into effect on July 1, 2024. In its first session, the AESO described the Market Power Mitigation Regulation and Supply Cushion Regulation and answered an initial round of stakeholder questions. In this session, the AESO shared its final details for implementing these regulations, provided an overview of the reporting processes and requirements for July 1, and addressed stakeholder questions and comments.
