On 21 December 2017, the Australian Energy Market Operator (AEMO) submitted a rule change request to the Australian Energy Market Commission (AEMC or Commission). The request seeks to amend the National Electricity Rules (NER) to remove the requirement to consider network constraints when publishing aggregate generation capacity for each region in the medium-term projected assessment of system adequacy (MT PASA). Network constraints will continue to be taken into account in other relevant outputs of the MT PASA.

This consultation paper has been prepared to facilitate public consultation on the rule change request and to seek stakeholder submissions.

This paper:

• provides a summary of, and background to, the rule change request;

• identifies a number of questions and issues to facilitate consultation on this rule change request; and

• outlines the process for making submissions.
