Forecast prices are prepared and published on WITS by the pricing manager according to the provisions set out in Part 13 of the Code. Prices from selected schedules are made available here for analysis and research purposes.
Price files published during any given day are compressed into a zip file, by forecast price type, and uploaded to EMI datasets in a single batch job early in the morning of the following day. The zipped up CSV price files are presented as is where is, i.e. we do not transform the data or in any other way reformulate it from that which WITS published. We do, however, slightly revise the CSV file naming convention.
At this time, all forecast prices except those emanating from the weekly dispatch schedule are made available dating back to 20 October 2018.
The CSV files contain six columns and have no header row. Taken in order, the columns are:
|Name||Date modified||File size|
|NRSL||25 Oct 2020|
|NRSS||25 Oct 2020|
|PRSL||25 Oct 2020|
|PRSS||25 Oct 2020|
Datasets are collections of files that often contain large volumes of data and are available for immediate download. Dataset users are typically analysts familiar with the electricity industry and have a need to obtain a large set of data or specific data on a regular basis.

Alternative methods are supported to connect to EMI datasets. These methods better facilitate downloading many files or automating regular downloads. See here for more information.
