In this section
Australian Energy Market Operator (AEMO) is conducting a consultation on proposed amendments to the Causer Pays Procedure and the Market Ancillary Services Specification (MASS) to complement Rule Changes related to the provision of Primary Frequency Response (PFR).
This consultation is being conducted under clauses 3.15.6A(k) and 3.11.2(b) of the National Electricity Rules (NER), in accordance with the Rules consultation requirements detailed in rule 8.9 of the NER.
AEMO has recently submitted two proposals to the Australian Energy Market Commission (AEMC) requesting to amend the NER to facilitate the provision of PFR by Generators under normal operating conditions. The first proposal aims to remove disincentives and inconsistencies in the NER that are impeding the provision of more PFR in the NEM under normal operating conditions. The second proposal relates to mandatory PFR requirements for all scheduled and semi-scheduled Generators. AEMO’s proposals, and the AEMC’s Consultation Paper can be found at on the AEMC's website under Proposed Rules to better control power system frequency.
Amongst other changes, Rule Change Proposal ERC0263 (Removal of disincentives to primary frequency response) proposes to amend clause 3.15.6(k) to align the requirements of the Causer Pays Procedure with the intent of the ‘causer pays’ process, as stated in clause 3.15.6A(k)(1).
AEMO has published a marked-up consultation draft of the Causer Pays Procedure with this notice, and an Issues Paper on the MASS. The proposed changes are:
- The Causer Pays Procedure will specify requirements for the provision of PFR that, if met by a Generator, will result in that Generator not receiving a negative ‘causer pays’ factor.
- The MASS should be altered so that the Contingency FCAS requirements do not incentivise a delay in the delivery of PFR.
This consultation will be limited to the changes identified in this notice, and the draft Causer Pays Procedure. In the coming months, AEMO intends to:
- Carry out a more extensive review and consultation on the Causer Pays Procedure; and
- Redraft the MASS and consult on various other changes associated with that document.
