Matters under consultation
This consultation paper commences the first stage of the standard rules consultation procedure conducted by AEMO to consider proposed amendments to the Constraints Formulation Guideline under National Electricity Rules (NER) 3.8.10(c).
AEMO is consulting on 2 changes as required for
- the National Electricity Amendment (Improving security frameworks for the energy transition) Rule 2024 No. 9 (ISF Rule) commencing 2 December 2025 - an added section for security service formulation constraints
- the National Electricity Amendment (Integrating price-responsive resources into the NEM) Rule 2024 No. 24 (IPRR Rule) commencing 23 May 2027 – including the new terminology “voluntarily scheduled resources”
AEMO is also using this opportunity to consult on changes proposed through the current consultation on the Congestion Information Resource (CIR) for changing the minimum threshold for left-hand side factors to 0.15 from 0.07.
Submissions to the Consultation paper are now closed. AEMO has received feedback related to the threshold for left-hand side factors. As a result, and as discussed with stakeholders, AEMO is undertaking further modelling and will publish the Draft paper on 4 July 2025 with the additional analysis.
