DISPATCHCASESOLUTION

DISPATCHCASESOLUTION shows information relating to the complete dispatch run. The fields in DISPATCHCASESOLUTION provide an overview of the dispatch run results allowing immediate identification of conditions such as energy or FCAS deficiencies.

The DISPATCHCASESOLUTION data is public.

Source

DISPATCHCASESOLUTION updates every 5 minutes.

Volume

Approximately 288 records per day.

Column Schema

SETTLEMENTDATE

Date and time of the dispatch interval (e.g. five minute dispatch interval ending 28/09/2000 16:35)

Warning

Despite what the name suggests, this is a datetime, not a date.

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

This column is mandatory, and a primary key.

Example: 2026/09/01 00:05:00

RUNNO

Dispatch run no; always 1

This column only ever takes one value: 1

(The SQL type is NUMBER(3,0).)

AEMO marked this column as mandatory, and a primary key. However, since it only ever takes one value, you can ignore it.

CASESUBTYPE

Overconstrained dispatch indicator: * OCD = detecting over-constrained dispatch * null = no special condition

SQL Type: VARCHAR2(3) Polars Type: pl.Categorical

This column is not mandatory.

Example: OCD

INTERVENTION

Intervention flag - refer to package documentation for definition and practical query examples

Warning

Unlike most tables with an INTERVENTION column, INTERVENTION is not a primary key of DISPATCHCASESOLUTION.

For more information, see the dedicated documentation page.

SQL Type: NUMBER(2,0) Polars Type: pl.Boolean

This column is mandatory (but not a primary key).

Example: 0

LASTCHANGED

Last date and time record changed

For more information, see the dedicated documentation page.

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

This column is not mandatory.

Example: 2026/09/01 00:00:07

NONPHYSICALLOSSES

Non-Physical Losses algorithm invoked occurred during this run

SQL Type: NUMBER(1,0) Polars Type: pl.Int8

This column is not mandatory.

Example: 0

SOLUTIONSTATUS

If non-zero indicated one of the following conditions: * 1 = Supply Scarcity, Excess generation or constraint violations * X = Model failure

SWITCHRUNINITIALSTATUS

Flag indicating the SCADA status for FCAS Interconnector dead-band. "0" if SCADA Status or requesting Constraint not invoked. "1" if SCADA Status AND requesting Constraint is invoked

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 2 MB when zipped, 19 MB 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
DISPATCH CASE_SOLUTION 2

This means that the CSV files start with metadata columns:

I,DISPATCH,CASE_SOLUTION,2,...
D,DISPATCH,CASE_SOLUTION,2,...
