Certification of Reserve Capacity

Relevant Level Methodology

Facilities nominating to use clause 4.11.2(b) of the Electricity System and Market Rules (ESM Rules) for their Certified Reserve Capacity (CRC) applications will be subject to the Relevant Level Methodology outlined in Appendix 9 of the ESM Rules.

The Relevant Level calculation is based on the Existing Load for Scheduled Generation (EFLSG), defined in Appendix 9 of the ESM Rules and explained in more detail in the help guide below.

Existing Facility Load for Scheduled Generation (EFLSG) 

AEMO is required to publish the EFLSG Trading Intervals within three Business Days of the Certification of Reserve Capacity window closing for the relevant Reserve Capacity Cycle (Appendix 9, Step 20, ESM Rules). The EFLSG Trading Intervals for the 2025 Reserve Capacity Cycle are provided in the file below:

The EFLSG Trading Intervals for the 2025 Reserve Capacity Cycle are provided in the file below: 

The EFLSG Trading Intervals for the previous Reserve Capacity Cycles are provided in the files below:

The forecast EFLSG Trading Intervals for previous Reserve Capacity Cycles are provided in the files below:

Note: Due to metering data updates and changes to the set of candidate Facilities that have applied for CRC, the EFLSG Trading Intervals published and used for the Relevant Level calculation may vary from the forecast EFLSG Trading Intervals.

The Facility adjustment factor calculation in step 17 of Appendix 9 of the ESM Rules uses two parameters, K and U. The values of K and U for the 2019 onwards Reserve Capacity Cycles have been determined by the ERA and are available here. 

New and upgrade Facilities – Accredited independent expert report

AEMO has developed an independent expert report guideline to assist accredited experts in their understanding of the report requirements and the purpose it serves in the Reserve Capacity Mechanism. AEMO held a workshop with accredited experts on 22 January 2019 and incorporated the feedback provided in the guideline below.

Information guide for independent expert reports in the Reserve Capacity Mechanism 

Please provide expected energy output estimates using this template

  • A 5% probability of exceedance of the Facility’s expected generation output value (in MW) for all the Trading Intervals that occurred within the last three years up to, and including, the last Hot Season.

The information below shows the experts AEMO has accredited to provide these reports.
