Unconstrained Intermittent Generation Forecasts (UIGF) for 5-Minute Pre-dispatch. AEMO plans to remove this table in a Data Model version release after 5.6.

Column Schema

DUID

DUID (or Area for non-scheduled) where this forecast applies

Warning

This column may contain funny characters such as / (slash) or # (hash). This may break hive-style partitioning.

For more information, see the dedicated documentation page.

SQL Type: VARCHAR2(20) Polars Type: pl.Categorical

This column is mandatory, and a primary key.

Example: W/HOE#2

FORECAST_PRIORITY

Unsuppressed forecasts with higher priority values are used in 5-Minute Predispatch in preference to unsuppressed forecasts with lower priority values

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

This column is mandatory, and a primary key.

INTERVAL_DATETIME

Interval within the current RUN_DATETIME where this forecast applies (dispatch interval ending)

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

This column is mandatory, and a primary key.

Example: 2026/01/20 00:05:00

OFFERDATETIME

Date and Time when this forecast submission was loaded

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

This column is mandatory, and a primary key.

Example: 2026/01/20 00:05:00

ORIGIN

Origin of this forecast (PARTICIPANTID, AWEFS/ASEFS, or another vendor)

SQL Type: VARCHAR2(20) Polars Type: str

This column is mandatory, and a primary key.

RUN_DATETIME

Date and Time of the first interval of 5-Minute Predispatch where the forecast applies (dispatch interval ending)

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

This column is mandatory, and a primary key.

Example: 2026/01/20 00:05:00

FORECAST_MEAN

Forecast MW value for this interval_DateTime

SQL Type: NUMBER(18,8) Polars Type: pl.Float64

This column is not mandatory.

FORECAST_POE10

Forecast 10% POE MW value for this interval_DateTime

SQL Type: NUMBER(18,8) Polars Type: pl.Float64

This column is not mandatory.

FORECAST_POE50

Forecast 50% POE MW value for this interval_DateTime.

SQL Type: NUMBER(18,8) Polars Type: pl.Float64

This column is not mandatory.

FORECAST_POE90

Forecast 90% POE MW value for this interval_DateTime

SQL Type: NUMBER(18,8) Polars Type: pl.Float64

This column is not mandatory.

New Data Timing

Publication of 5-Minute Pre-dispatch solution. Data includes all valid forecasts for that interval

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: Private

This table is not available in the public monthly MMSDM archive. Is is only available to registered market participants over FTP inside a VPN.

Deduplication and PDR Loader Configuration

The primary keys are:

• DUID

• FORECAST_PRIORITY

• INTERVAL_DATETIME

• OFFERDATETIME

• ORIGIN

• RUN_DATETIME

PDR Loader configuration does not mention this table, so it is unclear how to choose which row to keep when there are multiple rows for a given set of primary keys.

Look at the data and use your best judgement.
