Stakeholder Update - December 13, 2024
Following the first six REM Design Sprints, we have released a high-level design document covering each element of the market design, incorporating what we heard and discussed with stakeholders. The written stakeholder feedback period will be open until Jan. 17, 2025.
Additional direction from the Minister of Affordability and Utilities associated with the REM Market Design was provided on Dec. 10, 2024. View the Direction Letter and News Release.
There is an updated report and data file from Energy+Environmental Economics (E3) that contains some additional information and clarifications of the analysis, as requested by stakeholders in Sprint 6. This includes a number of updates to the analysis on the impact of the most recent version of the market power mitigation framework, edits to clarify the concepts presented on a number of slides and new slides (15, 21, 28, 33, and 94).
Materials posted this week include:
- REM High-Level Design and associated Stakeholder Feedback Form
- Updated E3 Restructured Energy Market Preliminary Report and AESO REM Modelling Results (Instructions - if needed)
- Dec. 12, 2024 Information Session Presentation and Recording
- Minister Direction Letter
- Design Sprint 6 Summary
Stakeholder consultations will help us continue to progress details on the final market design and work towards the ISO rule development stage. Watch for more information in mid-January on upcoming engagement opportunities.
Thank you for your interest, participation and contributions throughout the REM engagements. Your commitment and dedication have been instrumental in getting us to where we are. We look forward to continuing to work with stakeholders in 2025 to achieve a market design that sets our industry partners, the AESO and all Albertans up for a successful energy framework for the future.
Purpose
We have embarked on a multi-phased engagement with industry stakeholders to advance work on the new market design through the fall of 2024. It will be comprised of a series of information sessions, written feedback cycles, and consultation sprints to dive deeper into each workstream to explore and consider stakeholder perspectives and inputs prior to beginning the required regulatory processes early in 2025.
We will strive to ensure overall alignment with the stated REM objectives of:
- Reliability
- Affordability
- Decarbonization by 2050
- Reasonable implementation
Material will be covered according to six workstreams, including:
- Day-Ahead Market
- Market Power Mitigation
- Pricing and Reserve Market
- Market Clearing
- Intertie Participation
- Shorter Settlement

The AESO values stakeholder input and invites all interested parties to provide their feedback on the REM high-level design via the following stakeholder feedback form by Jan. 17, 2025 at 4 p.m. MDT. Please be as specific as possible with your responses. Thank you for your input.
Purpose
The AESO has been working extensively with industry stakeholders and market participants, partner agencies and government to ensure the Restructured Energy Market (REM) design provides a strong foundation for the Alberta electricity system, ensuring it’s affordable, reliable, investable and sustainable for generations to come.
We have released a REM High-Level Design that will be relied on to progress finalizing a complete design that best fits for Alberta’s purposes and reaches the REM objectives. We have progressed the design and narrowed the breadth of options that were being considered through our Design Sprint Sessions and the stakeholder feedback received so far. This round of written feedback will be used to build upcoming consultation activities that will assist in further refining and finalizing the REM.
The sections in this document correspond to those in the REM High-Level Design. We have identified specific areas where we are seeking additional input from stakeholders. Responses in each section are optional.
