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 analyses of the MSSC. The AESO is looking to make a recommendation regarding future MSSC limits based on its analysis and is looking at this engagement to capture suggestions and feedback from the industry.

Next steps

The AESO appreciates stakeholders' input up to this point and looks forward to reviewing the feedback on the options paper, which will allow us to complete additional analysis before proceeding with a decision on whether to change the MSSC limit in Alberta. The AESO will continue to consult with stakeholders on this initiative. The MSSC Options Paper is now published and we are reviewing the feedback we have received from stakeholders. The stakeholder comments we have received can be viewed in the "Options Paper Stakeholder feedback" located on the right-hand side of this page.

Forming a recommendation

The AESO will consider responses to the RFI, Solutions to Mitigate the instantaneous Impacts of Sudden Supply Loss, and any other relevant information, concurrently with the responses to this Options Paper when forming a recommendation. The AESO plans to develop recommendations by June 2023. Stakeholders will be able to engage in an industry session in June 2023 and submit written comments addressing the recommendations. The AESO plans to reach decisions on the path forward with MSSC Limits by December 2023.

We look forward to your continued participation and engagement on this initiative.
