Market Review: Open

Overview

On 29 October 2020 the Reliability Panel (Panel) published a:

  • final determination on amendments to the system restart standard (Standard) to account for changes made in the Commission’s System restart services, standards and testing rule change (SRAS rule). An interim Standard is published with the final determination.
  • draft determination on quantitative Standard settings for a combined Queensland sub-network. 

Final determination on the interim Standard

The Panel’s final determination on amendments to incorporate changes in the Commission’s SRAS rule was to amend language in the Standard’s qualitative guidance that is inappropriate for, or may create barriers to, AEMO’s procurement of SRAS from restoration support services and/or black start SRAS from non-generation providers.  

An interim Standard was published with the final determination.

Draft determination on Standard settings for a combined Queensland sub-network

On 16 October 2020, AEMO published a final determination to combine the existing North and South Queensland sub-networks to form a single Queensland sub-network.  

On 29 October 2020, along with its final determination on changes to the Standard’s qualitative guidance, the Panel published a draft determination on Standard settings for restoration level, timeframe, and aggregate reliability applying to a combined Queensland sub-network. The draft determination also included a locational requirement for AEMO to procure SRAS north of Bundaberg.   

Stakeholder submissions on the draft determination are invited by 26 November 2020. 

Consultation paper

On 20 August 2020 the Panel published a consultation paper for the review. The consultation paper outlined the key issues and questions the Panel will consider when determining the Standard, as well as the proposed process and timeframes for the review. 

Background 

On 24 June 2020 the AEMC issued terms of reference to the Panel to review the Standard.

The Standard specifies requirements applying to AEMO’s procurement of system restart ancillary services (SRAS) which are used to restart the power system in the event of a major supply disturbance or black system event.  

The scope of the review is to consider changes to the Standard to:

  • account for changes made in the Commission’s SRAS rule to the types of services AEMO can procure as SRAS and  
  • determine restoration timeframes, levels of restoration and aggregate reliability requirements for a single Queensland electrical sub-network in a final standard, should AEMO determine to combine the two existing Queensland sub-networks.
