National Electricity Rules – Rule 8.9 


Date of Notice: 13 May 2020 

This notice informs all Registered Participants and all other interested parties (Consulted Persons) that AEMO is conducting a consultation on the SRAS Guideline.   

This consultation is being conducted under clauses 11.123.2 and 3.11.7(f) of the National Electricity Rules (NER), in accordance with the Rules consultation requirements detailed in rule 8.9 of the NER.  

SRAS Guideline 

On 2 April 2020 the AEMC made the National Electricity Amendment (System restart services, standards and testing) Rule, with the substantive amendments commencing on 2 November 2020. Transitional rules require AEMO to review and amend the SRAS Guideline, and the Reliability Panel to review and amend the system restart standard (SRS).   

The NER amendments require additional matters to be included in the SRAS Guideline, as described below. 

SRAS definition: The NER amendments expand the definition of SRAS as follows: 

  • black start capability broadened  from generating units to include other types of facililities or a combination of facilities.    
  • to include capabilities to support and sustain the stable energisation of generation and transmission (restoration support). 

System restart tests:

The NER amendments introduce a new framework for broader testing of system restart paths beyond the delivery of SRAS to the network. To support this framework, the rules require the SRAS Guideline to include guidance on when system restart tests may be needed, and the data that AEMO needs from registered participants whose facilities are involved in those tests.  

SRAS procurement objective:

The NER amendments update the SRAS Procurement Objective to require AEMO to acquire SRAS to meet the system restart standard at the lowest long-term cost. The SRAS Guideline must include guidance on how AEMO will achieve this objective. 

AEMO is proposing, for consultation, a set of draft amendments to the SRAS Guideline to address the above requirements introduced by the amending rule. The amendments include clarifications and additional detail intended to better inform and assist participants’ understanding of SRAS capabilities and assessment.  

Boundaries of electrical sub-networks 

The SRAS Guideline incorporates AEMO’s determination of the boundaries of electrical sub-networks for which SRAS is procured, under clause 3.11.8 of the NER. AEMO is also consulting on a potential change to those boundaries.
