Introduction & Purpose
The Grid Readiness, Integration and Performance (GRIP) Requirements address reliability challenges with the Alberta Interconnected Electric System (AIES). They provide risk-informed performance criteria and technical assessments for connection projects.
The requirements inform interested parties planning new projects about the requirements and IDs they can expect to:
- Reduce unexpected compliance issues and operational risks during project energization
- Improve efficiency in execution phase of the AESO Connection Process
Note: While the AESO will review study reports as a courtesy, its focus will remain on study scope and assumptions. The AESO will not assume legal liability for these reviews.
Initial GRIP consultation with transmission facility owner (TFOs) began in 2025. The AESO is seeking feedback on the implementation timeline of these requirements and the regulatory pathway. Feedback is open until June 5, 2026.
Stakeholder Engagement
- Following the June 24 Information Session, applicable requirements will be identified based on project risk and added to Functional Specifications (FS) for relevant connection projects with an in-service date (ISD) after December 31, 2026
- Over the next few years, the AESO will transition new performance criteria into Authoritative Documents (AD) and guidelines into Information Documents (ID)
- Formal industry consultation will support this transition
