One of the features of the ancillary service market is that the costs for the frequency control regulation services are to be allocated in accordance with the contribution factors, as set out in clause 3.15.6A of the National Electricity Rules and detailed in the following Causer Pays Procedure.
| Causer Pays : Procedure for determining contribution factors “Causer Pays Procedure" 19 Aug 2009 | filename: 0160-0016.pdf |
 |
Under the Rules, AEMO must update these contribution factors every 4 weeks and publish the factors at least 10 business days prior to them being applied in the market.
The Rules also require AEMO to publish the historical data used to calculate these factors. This historical data is available on the AEMO web site at http://www.aemo.com.au/data/asdata.html.
Final factors used in settlements may vary slightly from previously published values due to minor error corrections.
In accordance with the Causer Pays Procedure and from 1 January 2009, AEMO will calculate contribution factors normalised according to region demand.
