Submission to the AEMC on the consultation paper on optimising contingency size in dispatch and allocating FCAS contingency costs

We welcome the opportunity to comment on the Australian Energy Market Commission's (AEMC) Consultation Paper on Optimising contingency size in dispatch and Allocating FCAS contingency costs.

While the AEMC has previously considered contingency size optimisation and runway cost allocation (for example, in the 2017 FCAS Framework Review and the 2022 FOS Review), this is the first time it will assess specific rule changes to address these issues for contingency frequency control ancillary services (CFCAS) in the National Electricity Market (NEM).
