Restructured Energy Market
Alberta’s electricity market is undergoing significant change to enhance reliability and maintain affordability as the province’s electricity grid continues to be transformed by new types of supply, new sources of demand and changing technology. As demand increases and our energy mix evolves, we need a market framework that attracts investment, keeps power affordable and ensures reliable electricity for all Albertans.
The Restructured Energy Market (REM) is the AESO’s response—developed in collaboration with policymakers, market participants and stakeholders. It modernizes Alberta’s energy-only market to strengthen system performance, improve cost outcomes and support investment in both new and existing technologies. The REM builds on two decades of competitive market experience to power Alberta’s future.

REM ISO Rules
REM ISO rules are required to implement and operate the REM.
In accordance with Section 20.01 of the Electric Utilities Act, REM ISO rules are approved by the Minister of Affordability and Utilities.
What’s Next?
Implementing the new market design will require a significant industry-wide effort. The pace of change will be rapid, with tight timelines for the AESO and market participants to adapt systems and processes.
Success depends on active collaboration and support from market participants, as the AESO cannot achieve this this transition alone. Without shared effort, meeting the new market timeline will be challenging.
The Market Transition will be carefully managed to ensure industry readiness and minimize disruption.
