GENCONSETINVOKE

GENCONSETINVOKE provides details of invoked and revoked generic constraints. GENCONSETINVOKE is the key table for determining what constraints are active in dispatch, predispatch and PASA. GENCONSETINVOKE also indicates whether constraints are for interconnector limits, ancillary services, etc.

GENCONSETINVOKE is public data. All participants have access to this data.

Source

GENCONSETINVOKE updates each time a generic constraint is invoked or revoke time is altered. Once past the time, these times cannot be altered.

Note

The Replica software does not handle the deletion of GENCONSETINVOKE records. To workaround this problem, the field STARTAUTHORISEDBY indicates whether a constraint set invocation is applicable. A non-null value for the STARTAUTHORISEDBY field indicates that the constraint invocation is active. Essentially inactive invocations have a null value for the STARTAUTHORISEDBY field. To remove inactive invocations from queries on the GENCONSETINVOKE table, add the following text to the where clause "and STARTAUTHORISEDBY is not null".

Column Schema

INVOCATION_ID

Abstract unique identifier for the record. Allows Invocations to be modified without affecting PK values

SQL Type: NUMBER(9) Polars Type: pl.Int32

This column is mandatory, and a primary key.

Examples: 221609, 236959

ASCONSTRAINTTYPE

Constraint type (e.g. ancillary services). This also flags where a constraint is an interconnector or intra-region network limit.

SQL Type: VARCHAR2(10) Polars Type: pl.Categorical

This column is not mandatory.

Examples:

  • INFLEXIBLE
  • NETWORK
  • SSE

ENDAUTHORISEDBY

user authorising revoke.

SQL Type: VARCHAR2(15) Polars Type: str

This column is not mandatory.

ENDDATE

Market date end

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

This column is not mandatory.

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

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

ENDINTERVALDATETIME

The settlement date and time corresponding to the last interval to which the constraint set is to be applied.

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

This column is not mandatory.

Example: 2026/09/01 07:20:00

ENDPERIOD

Dispatch interval number end

SQL Type: NUMBER(3,0) Polars Type: pl.Int16

This column is not mandatory.

Examples: 2, 288

GENCONSETID

Unique generic constraint set identifier

SQL Type: VARCHAR2(20) Polars Type: str

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

Examples:

  • #DRYCGT1_DE
  • #DRYCGT2_DE
  • #QPS5_DE
  • #R036705_RAMP
  • #R036713_RAMP
  • #R036714_RAMP
  • #R036715_RAMP
  • #R036716_RAMP
  • #R036717_RAMP
  • #R036718_RAMP

INTERVENTION

0 is not intervention, 1 is intervention and causes dispatch to solve twice.

Warning

Unlike most tables with an INTERVENTION column, and contrary to the official documentation, INTERVENTION takes values N and Y not 0 and 1.: 1 N: 0

Warning

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

For more information, see the dedicated documentation page.

SQL Type: VARCHAR2(1) Polars Type: pl.Boolean

This column is not mandatory.

AEMO's documentation says this is a string type, even though it is logically a binary value. You may want to map letters to a boolean with {'Y': 1, 'N': 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 03:10:58

STARTAUTHORISEDBY

User authorising invoke, indicating a constraint set invocation is applicable (i.e. non-null). A null value indicates inactive invocation.

SQL Type: VARCHAR2(15) Polars Type: str

This column is not mandatory.

Examples:

  • AAShfaq
  • AAshfaq
  • ABRAHAMY
  • ANL
  • BASHFORD
  • BATCH
  • BCHHETRI
  • BOGDANV
  • BSANGHAVI
  • Batch

STARTDATE

Market date of start

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

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

Example: 2026/02/08 00:00:00

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

STARTINTERVALDATETIME

The settlement date and time corresponding to the first interval to which the constraint set is to be applied.

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

This column is not mandatory.

Example: 2026/02/08 16:40:00

STARTPERIOD

The first dispatch interval of the invocation being the dispatch interval number starting from1 at 04:05.

SQL Type: NUMBER(3,0) Polars Type: pl.Int16

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

Examples: 1, 282

SYSTEMNORMAL

Flag to indicate if the constraint set is a system normal (1) or an outage set (0)

SQL Type: VARCHAR2(1) Polars Type: pl.Boolean

This column is not mandatory.

Examples:

  • 0
  • 1

New Data Timing

When a generic constraint is invoked or the revoke time is altered

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 418 KB when zipped, 4 MB as unzipped CSV.

Deduplication and PDR Loader Configuration

The primary keys are:

The transaction type is "INSERT-UPDATE", which means that you will likely see duplicate data with different values.

You should deduplicate by sorting based on LASTCHANGED, within each group of primary keys.

PDR Loader configuration is:

Report Name Report Subtype Version
GENCONSETINVOKE NULL 2
GENERIC_CONSTRAINT GENCONSETINVOKE 2

This means that the CSV files start with metadata columns:

I,GENCONSETINVOKE,NULL,2,...
D,GENCONSETINVOKE,NULL,2,...

or

I,GENERIC_CONSTRAINT,GENCONSETINVOKE,2,...
D,GENERIC_CONSTRAINT,GENCONSETINVOKE,2,...

ROW_FILTER_TYPE is LASTCHANGED
