On 25 January 2013, AEMO commenced formal consultation on the system restart ancillary services (SRAS) arrangements in the National Electricity Market (NEM) with the publication of its Issues and Options Paper. The objective of the SRAS review is to ensure the SRAS arrangements deliver value to energy consumers through an appropriate price and service balance.
Extension of SRAS Final Report
AEMO is extending the publication date of the SRAS Review Final Report until late 2013. The extension follows stakeholder responses and is to allow sufficient time for AEMO to obtain independent review on its power system studies. These will be reviewed to ensure AEMO’s recommended changes to the SRAS quantities and number of electrical sub-networks meet the System Restart Standard.
AEMO has released the final report from the SRAS review:

The updated SRAS Review’s key milestones and revised indicative timeline are set out in the table below:
|KEY MILESTONE||INDICATIVE TIMELINE|
|Issues and Options Paper published||25 January 2013|

|Final Report published||Late 2013|
On 10 May 2013, AEMO published the Draft Report which describes AEMO’s recommendations for changes to the SRAS arrangements.
The SRAS Draft Report outlines the following key recommendations for improving the SRAS arrangements:
a) To reduce the quantity of SRAS procured to meet the System Restart Standard (SRS) by a combination of the following measures:
• Procuring SRAS on the basis of a regional, rather than NEM-wide, black system condition, while still meeting the SRS
• Re-defining the electrical sub-networks, reducing their number from 10 to seven.
• Procuring one SRAS in each electrical sub-network except Tasmania, where two would be required to provide sufficient diversity and contingency. On the mainland, supply from adjacent regions can be used to support SRAS sourced within a region, providing sufficient diversity and contingency to meet the requirements of the SRS.
• Creating one SRAS definition to replace the current definitions of primary and secondary restart services.
b) Developing proposed rule changes to identify and manage non-competitive outcomes in the SRAS tender process, along similar lines to those in effect under clauses 3.11.5 (h)-(i) of the NER for the Network Support and Control Ancillary Services (NSCAS) tender process.
c) To improve cost-reflective recovery for SRAS with respect to the benefits of a service, by allowing the costs of SRAS to be recovered on a regional basis.
d) To monitor and review the effectiveness of the current procurement process in relation to the SRAS objective in the NER by reviewing outcomes from the next tender process, after the implementation of SRAS quantity reductions, against comparable international benchmarks.

On 25 January 2013, AEMO released an Issues and Options Paper which explained that SRAS costs had increased significantly in the last few tender processes. The paper discuss a range of issues including weather the SRAS objective was being met and how AEMO could improve the value SRAS services.
