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.
In proceeding 29006, ten participants submitted written arguments to the Alberta Utilities Commission (the Commission or AUC) following rounds of extensive information requests (IRs) and evidence. A virtual hearing for reply arguments is scheduled for April 23, 2025.
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.
The Alberta Electric System Operator (AESO) has held 6 sprint sessions as part of their multi-phase engagement with industry stakeholders on the new energy market design.
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 28989, The Alberta Utilities Commission (The Commission or AUC) approved the Alberta Electric System Operator’s (AESO) application to update its Rate Demand Opportunity Service (DOS), with reasons to follow.
In Proceeding 27777, the Alberta Electric System Operator (AESO) submits to the Alberta Utilities Commission (the Commission) its 2023 Independent System Operator (ISO) Tariff Application. In its application, the AESO explains the increases to its revenue requirement forecast, proposes an overall increase to the ISO tariff and the maximum investment levels, and provides new Generating Unit Owner’s Contribution (GUOC) rates.
The 2023 Business Plan and Budget Proposal of the Alberta Electric System Operator (“AESO”) outlines the organization’s priorities and expenditures for the upcoming year. In developing this proposal, the AESO explained that stakeholders met one-on-one with a subset of AESO board and executive members to share their perspectives on what they believed the AESO should be focusing on in the near term. The AESO used these insights to inform its 2023 priorities.[1]
In Proceeding 26911, the Alberta Utilities Commission (the “Commission”) issues its decision regarding the proposed regional and bulk transmission rate design of the Alberta Electric System Operator (“AESO”). Alberta’s current regional and bulk transmission rate design recovers transmission costs through energy and coincident peak (“CP”) demand billing determinants. However, most intervenors agree that the associated CP charge overstates the cost of using the grid at peak times, allowing some customers to lower their bills by strategically reducing consumption. The AESO proposed a new rate design that lowers the influence of the CP charge and raises the energy charge to alleviate this issue.
