REM ISO Rules

The REM ISO rules are the foundation for Alberta’s transition to a modernized electricity market, providing the framework for the AESO and market participants to develop the processes and systems needed to implement the REM design. 

Aligned with the REM’s final design, the ISO rules provide the structure and flexibility needed to support a reliable, efficient, competitive and adaptable market, drawing on best practices from other Independent System Operators (ISOs). 

Key Features of the REM ISO Rules 

• Implementation Framework: The rules outline the requirements for market operations, ensuring that critical systems and processes are in place  
• Clear Requirements: The rules outline all the requirements for market operations so that critical systems and processes can be developed and implemented ahead of the launch of REM   
• Stakeholder Engagement: Developed with stakeholder input, the REM ISO rules reflect market participant needs and Alberta’s unique energy landscape.

• Develop supporting materials such as manuals and information documents for clarity and guidance.
• Run readiness programs to help market participants understand and adapt to new rules and systems.
• Engage in ongoing dialogue to address emerging needs and to make improvements where relevant.
