Aaron Engen, AESO CEO, presented at IPPSA and provided a high-level view to the work underway at the AESO to prepare for a successful market transition, the planning and timeline for IT system testing and implementation, and how the AESO will support market participants to prepare and transition successfully to the new market. An overview of his remarks is available here, visit aeso.ca/transition for more information on how the AESO is preparing for the electricity framework transition.

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.
