Market Participant Self-Assessment #1

We are asking Market Participants (MPs) to complete Market Participant Self-Assessment #1 by Monday, Nov. 16, 2026.

It will take approximately 10 to 15 minutes to complete and will gather information about your organization’s:

  • awareness of REM;
  • participation in MPR initiatives; and
  • progress in establishing an internal readiness program.

How to complete the assessment:

  • Have one person per MP complete the assessment.
  • Identify the MP you are responding on behalf of and include all applicable Pool Participant IDs if responding for multiple entities.
  • Answer each question and use the optional section at the end to share additional feedback or anticipated risks and challenges.
  • Submit your response by Monday, Nov. 16, 2026.

Complete Market Participant Self-Assessment #1

The AESO will use the responses to identify emerging readiness risks, areas where additional support may be needed, and overall progress toward REM implementation. Results will be aggregated in Market Readiness Report #1, planned for release in December. Individual MPs and their responses will not be identified or attributed in the report.


Readiness Journey: Integrated View



Introduction

We are committed to a robust transition support for all Market Participants to the Restructured Energy Market (REM) implementation. This will include clear communication, supporting resources and materials to understand and adopt changes, and detailed training to transition systems where required.

Through the transition, Market Participants will have opportunity to provide input, so we understand your implementation requirements and operational impacts.

Your feedback will help us identify readiness needs, prioritize engagement activities, and ensure that our approach to Market Participant readiness addresses your organization’s key concerns.

Engagement opportunities for REM implementation will be shared with stakeholders as they are determined.

    We will be hosting a full-day hybrid stakeholder session on Tuesday, March 24 for Market Participants to learn more about the AESO’s high-level plan guiding the work and preparations required for the successful implementation of the REM.

    This session is intended for those responsible for leading and coordinating their organization’s REM implementation readiness across operations, technology/systems compliance and change management. Ideal participants will include the project manager and/or technical lead overseeing implementation planning activities.

    Due to space constraints, only one representative per organization may register to attend in-person. Others can join virtually and will have opportunities to participate and ask questions.

    Session Objectives:

    By the end of this session, Market Participants will:

    1. Understand the high-level plan and key milestones required for REM implementation including system updates.
    2. Gain visibility into the major changes to systems and impact of those changes.
    3. Understand the AESO’s approach and supports for enabling the transition to the new market.
    4. Understand the expectations of Market Participants to support their own readiness activities.
    5. Understand the AESO’s overall engagement plan for the ISO Manuals and Information Documents related to the REM ISO rules, and further review of the REM ISO rules.
