FORECAST_PRIORITY

Priority of the forecast run used for the DS run, tracks to ROOFTOP_PV_FCST_P5_RUN.FORECAST_PRIORITY.

SQL Type: NUMBER(10,0) Polars Type: pl.Int64

This column is not mandatory.

FORECAST_RUN_DATETIME

Code Examples

Polars

Casting is enums, categoricals etc is not essential, but may speed up parsing. Swapping int for pl.UInt16, pl.Int32 would also speed up parsing. However some of the datatypes are inferred, so they may be wrong.

This code deduplicates for you. Deduplication is normally only required across multiple months.

This code assumes that all columns are present, which may not be true for older files.

Availability

AEMO's documentation states that this table's visibility is "Public". However, it is not available in the public monthly MMSDM archive. AEMO probably call this public because it is available to all market participants over private FTP.

There is a chance that is is still public to non-participants. It may only be available for some months; or (rarely) it may be available in a non-standard location.

Deduplication and PDR Loader Configuration

The primary keys are:

• AREAID

• RUN_DATETIME

The transaction type is "insert", which means that you will usually not see duplicate data. If you do, you can deduplicate based on the primary keys, without sorting first. Rows from different files with the same primary keys should have the same values.

PDR Loader configuration is:

Report Name	Report Subtype	Version
DISPATCH	ROOFTOP_PV_FCST_TRK	1

This means that the CSV files start with metadata columns:

I,DISPATCH,ROOFTOP_PV_FCST_TRK,1,...
D,DISPATCH,ROOFTOP_PV_FCST_TRK,1,...
