MTPASA_RESERVELIMIT

MT PASA input table defining a MT PASA Reserve Requirement within a single set. An MT PASA Reserve Requirement can span more than one region.

Source

MTPASA_RESERVELIMIT is updated on an ad hoc basis when a new Reserve Requirement is published.

Volume

~20 rows per year

Column Schema

EFFECTIVEDATE

Trade date when the set of reserve requirements become effective

SQL Type: DATE Polars Type: pl.Date()

This column is mandatory, and a primary key.

Example: 2010/04/22 00:00:00

Note that AEMO represents dates as datetimes with a midnight time component.

RESERVELIMITID

New Data Timing

Ad hoc, when a new Reserve Requirement is published

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

Visibility: Public

This table is in the public monthly MMSDM archive.

I have collated the list of all those files into one place, in this CSV metadata file. (Columns year, month, url, compressed_size in bytes).

The earliest available data is month 1 of 2015. The most recent available data is month 9 of 2026.

Every month in between has a file. (No gaps.)

Data Size

Each year of data is approximately 17 KB when zipped, 174 KB as unzipped CSV.

Deduplication and PDR Loader Configuration

The primary keys are:

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
MTPASA RESERVELIMIT 1

This means that the CSV files start with metadata columns:

I,MTPASA,RESERVELIMIT,1,...
D,MTPASA,RESERVELIMIT,1,...
