get_tables returns empty list for 2024-08 onwards

[nickmasonsmith]

Purely coincidentally, my first attempt at using NEMSEER was with August 2024. It appears that from August 2024 onwards, NEMSEER is unable to locate relevant tables.

Minimum worked example:

import nemseer
print(nemseer.get_tables(2024,7,'P5MIN'))
print(nemseer.get_tables(2024,8,'P5MIN'))

Keen to hear any suggestions - did I hear something about AEMO changing things behind-the-scenes?

Hi Nick,

I've also encountered this problem. Initially, I though it wasn't a bug caused by NEMSEER, so I jumped into AEMO's original websites where AEMO publishes raw data. If you look at https://www.nemweb.com.au/Data_Archive/Wholesale_Electricity/MMSDM/2025/MMSDM_2025_01/MMSDM_Historical_Data_SQLLoader/PREDISP_ALL_DATA/ and https://www.nemweb.com.au/Data_Archive/Wholesale_Electricity/MMSDM/2024/MMSDM_2024_08/MMSDM_Historical_Data_SQLLoader/PREDISP_ALL_DATA/ (corresponding to 2024/07 and 2024/08), you can find that AEMO has changed their file names, which lead to the failed file fetch.

Cheers, Jinhao

Ahh thanks @nickmasonsmith and @StephLee12. Wondering if either of you two might have some time to incorporate a change to handle this in a PR?
