Consultation
AEMO is publishing the final determination of the Credit Limit Procedures Version 2.
Background
The new prudential standard in the National Electricity Rules took effect on 1 November 2012 and the first maximum credit limit (MCL) review in accordance with the new credit limit procedures (CLP) was made effective on 28 November 2013.
As a result of the introduction of the Clean Energy Act 2011 (CEA), the current calculation of price (PR) in the CLP includes an adjustment for carbon price. This adjustment increases the historical regional reference prices (RRP) by $20/MWh for each trading interval prior to 1 July 2012.
The Australian Government repealed the CEA on 17 July. As as result of the repeal, the CLP must take into account the removal of the carbon price as this is a step change which the CLP calculation cannot adequately address in an appropriate timeframe.
Additionally, AEMO has reviewed the MCL determination for participants included in section 10.2 of the CLP which included:
- New market generators and small generation aggregators that are not yet generating.
- Existing market participants that are inactive and planning to deregister.
On 2 May 2014, AEMO commenced its first stage consultation on the proposed changes in the Credit Limits Procedures Version 2. A draft Credit Limit Procedures Version 2 was provided along with supporting documentation.
One submission was received in response to the first stage consultation.
On 24 June 2014, AEMO published its draft determination on the Credit Limit Procedures V2. Changes included:
- Rules version updated to the current version.
- Clarification that an inactive market participant is not restricted to one who is planning to deregister.
Final Determination
On 1 August 2014, AEMO published its final report and determination on the Credit Limit Procedures V2. Changes included:
- Rules version updated to the current version.
The implementation of the initial review with prices adjusted to remove the direct impact of carbon is likely to align with the 2014 Shoulder 2 scheduled review which will become effective on 2 September 2014. Please refer to the summary of changes document for the timeline for implementation of the initial review.
A provisional MCL calculator is provided to support participants to estimate their MCL level for 2014 Shoulder 2 season. The parameters used in this calculator are provisional and they will be finialised prior to the commencement of the Should 2 MCL review.
