Modification of sub-regional actual rooftop PV data in the ROOFTOP_PV_ACTUAL report

We are seeking participant feedback about a proposal to stop publishing the sub-regional actual rooftop PV data as you can identify it where the REGIONID field is equal to the following: QLDC, QLDN, QLDS, TASN, TASS.

We will present this proposed change in the next MSUG 2 April 2025, where participants can provide feedback.

AEMO will update the participants by the next MSUG.

Open

Distribution loss factor data is only available in the DUDETAILSUMMARY table. Can AEMO provide the source for this data so participants are not dependent on this table?

If participants are interested and see the value, provide Feedback by 13 November 2024 so we can consider it as a future service

Is AEMO providing a script to back populate the Sparse Data Model with historical Bid Offer Period data?

Currently, we are not planning that but there are 2 approaches we can consider:

  • One approach is to set the PERIODITTO field equal to the PERIODID field for all the historical data ensuring participants have a consistent representation, although this is inefficient storage

  • A more comprehensive approach is to collapse the historic data into a sparse model, to realise the storage benefits

Please provide Feedback by 13 November 2024
