MSUG Action Items

Sparse data filter configuration example

Participants requested an example of the sparse data filter configuration

Publishing sub-regional data

We are seeking participant feedback to include sub-regional data in the data model and evaluate the feasibility of publishing this data in future releases.

The new tables will be introduced in the next data model update (v5.6), expected in November 2025. Until then, the sub-regional data can be found in Nemweb and the Data Interchange as non-data model reports.

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.

The proposed change was presented to participants in the December 2024 Intermittent Generator Forum.

Proposed changes presented at MSUG 2 April 2025.

Data Model - Noting changes to Settlement data tables impacted by IESS

Awaiting confirmation before finalising the update

The Data Model 5.5 release will include changes to settlement data tables impacted by the FPP rule change. From 8 June 2025 onwards, settlements will be performed on the new dispatch FCAS requirements tables, and the old FCAS tables will no longer be maintained. Participants must transition to using the new FCAS requirement tables by this date.

See 3 Participant Impact

Data Model - Amend primary key on Demand operational forecast table

If there is broad support for the change from participants, AEMO will consider implementing the change

We will not change the primary key definition at this time. However, participants are encourage to modify the primary key themselves by adding a column, such as LOAD_DATE, to retain historical forecast data.

Evaluate feasibility of implementing an FCAS requirement for 7-day pre-dispatch within an additional 7-day dispatch timeframe

Request sent to business team. It is being considered but currently in backlog due to resourcing constraints. Will reopen once a solution and schedule is determined

FPP Design - Participants noted a LastChanged field would be beneficial in Data Model for data management and handling retrospective changes made by AEMO

The designs will be reviewed and changes will be made if necessary

Provide Feedback by 7 May 2025 so we can consider it as a future service

A DUDETAILSUMMARY table refresh results in duplicate records

For details about the issue and a workaround, see DUDETAILSUMMARY table refresh issue resulting in duplicate records

A fix has been deployed in the pre-production environment, and it will be progressed to production with the Data Model 5.5 release.

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

The WA market data has become a lot more complex with the new reformed WEM market starting last October.

Explore the possibility of fetching and loading WEM data into a data model similar to EMMS.

Obtain feedback from other participants and AEMO to investigate and publish a concept paper on how this could work.

AEMO has begun internal discussion with the WA Market Solutions team around the proposal. Depending on this discussion and presenting the same proposal in the WA Market Forum, and wider interest from all relevant stakeholders, AEMO can make a determination on this item.

For dispatchable or available generation in Dispatch Regions, can we assume all fields referring to different aggregate quantities for Generation or Load include the BDU components?

Can we get this information documented in technical specifications or Data Model documentation?

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

AEMO has an action to determine the right level of clarity on the data model and that is reflected in updated comments.

Is AEMO planning to update the comments in the PASA tables?

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

Participants must provide specific feedback about what kind of information they are looking for.

Does AEMO have a plan to fill in some of the gaps with registration data, for example, the DUALLOC?

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

AEMO publishes data through a centrally maintained Data Model for the NEM, GBB, and DWGM, Is there an intention to do the same for the WEM?

Currently, we have no formal plans, but if participants are interested and see the value, provide Feedback by 13 November 2024 so we can consider it as a future service

Awaiting participant responses.

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
