In accordance with rule 492 of the National Gas Rules, the Australian Energy Market Operator (AEMO) is conducting a review of market parameters in the Short Term Trading Market (STTM). AEMO is required to use the extended consultative procedure set out in rule 9A of the National Gas Rules.
While there is no mandated review of the market parameters in the Declared Wholesale Gas Market (DWGM), AEMO is taking the opportunity to review the DWGM market parameters in conjunction with the STTM parameter review.
The parameters being reviewed are:
Parameter |
STTM |
DWGM |
Market Price Cap (STTM) / VoLL (DWGM) |
$400 per GJ |
$800 per GJ |
Minimum Market Price |
$0 per GJ |
$0 per GJ |
Administered Price Cap |
$40 per GJ |
$40 per GJ |
Cumulative Price Threshold (CPT)
|
110% of Market Price Cap $440 per GJ |
$1,800 per GJ |
CPT Horizon (STTM) Cumulative Price Period (DWGM) |
7 days |
35 Scheduling Intervals (7 days) |
Approach
AEMO has appointed a consultant (Market Reform Pty Ltd) to model and make recommendations as to the values of the following parameters in both the STTM and DWGM:
- Market Price Cap / VoLL
- Administered Price Cap
- Cumulative Price Thresholds
AEMO will review the values of the following parameters in both the STTM and DWGM:
- Minimum Market Price
- CPT Horizon / Cumulative Price Period
Should AEMO’s final report recommend changes to any market parameter, AEMO will initiate an appropriate regulatory change process to implement the new parameters with effect from 1 July 2020. Under rule 492(3) of the National Gas Rules, changes to the relevant parameter may come into effect from 1 July 2019 where assumptions on which the current parameter values were based have been shown to be materially incorrect.
