A Modernized Market for Alberta’s Evolving Grid
View the Information OverviewAlberta’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.
Leveraging insights from stakeholder consultations, the REM Design details key components and facilitates the transition from high-level market design to formal ISO REM rules.

“Our new market design marks a major milestone in Alberta’s electricity sector. It reflects our shared commitment to a reliable, affordable and investment-ready market that serves Albertans today and prepares for the future. It strikes the right balance between competing interests to deliver a practical design in the public interest. I sincerely thank AESO staff, industry stakeholders and all contributors whose expertise made this possible.” |
