The AEMC today released a consultation paper on a rule change request which would:

  • seek to improve transparency regarding the frequency control framework
  • require AEMO and the AER to report on the performance of frequency and the frequency control ancillary services (FCAS) market.

The rule change request was submitted by AEMO and the AER to action the recommendations made by the AEMC in its Frequency control frameworks review final report, which, among other things, was aimed at improving the transparency of the framework. 

The frequency control framework is central to maintaining the stability of the power system, which operates within defined technical limits.

The consultation paper seeks stakeholder input on the proposal, including on the:

  • specific metrics AEMO and the AER should report on, and
  • preferred frequency of reporting.

This request was submitted as two separate rule change proposals. These have now been consolidated, as they both raise issues related to the frequency control framework.

This rule change request seeks to improve transparency by formalising reporting already undertaken by AEMO and the AER. As a result, the AEMC considers this to be a non-controversial rule change proposal and is proceeding under an expedited process.

Subject to any objections to the expedited process, there will only be one round of consultation. Objections to the use of the expedited process must be lodged by 13 June 2019.

Submissions on the rule change request are due by 27 June 2019. A final rule is due on 25 July 2019.

The AEMC’s Frequency control frameworks review final report detailed the Frequency control work plan which in turn sets out actions the Commission, AEMO and the AER will take to support the stable and secure operation of the power system in relation to frequency control. More transparent and regular reporting of frequency performance is part of this collaborative work plan.
