MSUG Action Items

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

AEMO is currently having internal discussions on a plan to populate DUDETAILSUMMARY table. AEMO is testing this internally to check for gaps.

AEMO will update the participants by the next MSUG.

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.

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 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.

Please provide Feedback by 13 November 2024.
