Historical Inputs `BIDPEROFFER_D` post February 2021

[MattAmos]

Firstly, I would like to sincerely compliment all of the work completed on NEMpy thus far, the functionality and thorough documentation has been very helpful!

Following the 30 minute to 5 minutely bid changes around February/March 2021, the NEMweb monthly archives post February 2021 no longer seem to contain the PUBLIC_DVD_BIDDAYOFFER_D tables: February 2021 monthly archive vs March 2021 monthly archive

As a result, the mms_db.DBManager.populate call fails when attempting to gather data for March 2021 onwards:

Downloading MMS table for year=2021 month=2
Downloading MMS table for year=2021 month=3

Are there any plans to patch this and use an alternative table that is still supplied in the monthly archives, and/or do you have any advice for temporarily patching this in the meantime?

Thanks in advance.

Hi @MattAmos

Thanks for your feedback!

I had seen this data missing a little while back, I was hoping it was temporary, and that the missing PUBLIC_DVD_BIDDAYOFFER_D data would be uploaded. Doesn't look like this is going to happen, but I might try and contact AEMO just to check.

If PUBLIC_DVD_BIDDAYOFFER_D has been retired, then we will need to rely on PUBLIC_DVD_BIDDAYOFFER, and use some additional filters on the query to get the right bids for each dispatch interval, as PUBLIC_DVD_BIDDAYOFFER contains rebids. This will probably apply to PUBLIC_DVD_BIDPERFOFFER_D as well.

I'll get back to you when I have more info.

Cheers, Nick

@MattAmos this should be fixed in the latest release, update with pip, see notes here: https://github.com/UNSW-CEEM/nempy/releases/tag/v1.1.3
