Purpose
The purpose of this engagement is to inform industry on the Most Severe Single Contingency (MSSC) in Alberta, what it is and its current limits, and to report on the AESO’s recent analysis of the MSSC in an Evaluation of the Most Severe Single Contingency Options Paper (MSSC Options Paper). Stakeholder suggestions and feedback on the MSSC Options Paper will be considered in the AESO's decision on whether to change the MSSC limit in Alberta.
Next steps
The AESO appreciates the feedback provided by stakeholders on the MSSC Options Paper. Stakeholder comments and submissions can be viewed under Submissions > Options Paper Stakeholder Feedback, located on the right-hand side of this page. On Feb. 21, 2023, a Summary of Stakeholder Feedback was published for review.
Forming a decision
The AESO is considering stakeholder suggestions and feedback received through this engagement initiative in conjunction with the following to inform our decision on whether to change the MSSC limit:
- Responses to the RFI for Solutions to Mitigate the Instantaneous Impacts of Sudden Supply Loss
- Assessment of grid reliability
- Future transformational changes to the AIES
- Other relevant information
The AESO plans to form a decision by June 2023, which will be presented at a stakeholder information session. We will provide an overview of how the decision was reached and respond to questions.
