Data is provided in comma delimited flat file format to enable access to a range of market data. Recent files are stored in a directory for current reports, and older files are moved into the archive reports directory.Prices quoted in these files are exclusive of GST.
File names include date and time stamps and a unique identifier to differentiate the files: eg.
Short Term PASA
This report is published every 2 hours and provides detailed disclosure of short-term power-system supply/demand balance prospects for six days following the next trading day. The information is provided for each half-hour within the report period. (Please see note)
Medium Term PASA
This file is produced weekly (on Tuesdays) and lists the medium-term supply/demand prospects for the period two years in advance. The information is provided for each day within the report period.
Each week participants must submit forecasts of availability to AEMO for the next 24 months, commencing eight days after the publication date of the Medium-Term PASA report. These forecasts form the basis of the Medium-Term PASA report that will be produced the following week. (Please see note)
Medium Term PASA Region Availability
This report file contains, for each region and each day over the current MT PASA run timeframe (next 104 weeks, starting Sunday):
- the region-aggregate offered MT PASA Availability for all scheduled generating units registered on that day; and
- the latest date time an MT PASA offer was submitted for any scheduled generating unit for that region and day
The aggregated data is derived solely from the MT PASA offers provided by Scheduled Generators under clause 3.7.2 (d)(1) of the National Electricity Rules. If no MT PASA offer exists for a particular week, the aggregation calculation uses the latest MT PASA offer from the previous week.
The report is updated at 0900, 1200, 1500 and 1800 hrs EST each day (excluding Sundays), and published around 18 minutes later.
The report will assist Scheduled Generators in meeting their obligations under the insider trading provisions of the Commonwealth Corporations Act 1989, by allowing them to provide timely disclosure of the implications of their generation outage plans prior to seeking financial cover through securities dealings.
The National Electricity Market registration classifications of Anglesea Power Station Unit 1 (dispatchable unit ID: APS) and Yarwun Power Station Unit1 (dispatchable unit ID: YARWUN_1) are market non-scheduled generating units. However, it is a condition of the registration of these units that the Registered Participants comply with some of the obligations of a Scheduled Generator. Both units are dispatched as scheduled generating units with respect to their dispatch offers, targets and generation outputs. Accordingly, information about APS and YARWUN_1 is reported as scheduled generating units information.
The Tumut 3 Pumps (dispatchable unit ID: SNOWYP) are not classified as scheduled load in the National Electricity Market. However, they are required to comply with some of the obligations of a Market Customer in respect of a scheduled load. The Tumut 3 Pumps are dispatched as if they were scheduled loads with respect to their dispatch bids, targets and consumption. Accordingly, information about SNOWYP is reported as market scheduled load information.
