Evaluation of MSSC
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 industry.
Next steps
The AESO appreciates stakeholders' input and acknowledges the consistent feedback for the AESO to provide a plan or options paper with additional information and 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 and plans to develop and publish an Options paper in Q3 2022. The Options paper will assess and evaluate whether to increase MSSC or maintain the status quo, and all options considered for increasing MSSC, if that is the recommended path forward. The AESO will seek stakeholder written feedback on the Options paper and will host a stakeholder session targeting Q4 2022 to provide stakeholders an opportunity to ask clarifying questions on the Options paper prior to submitting their comments.
We look forward to your continued participation and engagement on this initiative.
