Table schema

Column Official MMS Datatype GR-MMS Datatype Comment
INTERVAL_DATETIME datetime(3) 🔑 datetime2(0) 🔑 Date and time of the trading interval (DD/MM/YYYY HH24:MI:SS) fixed to the UTC+10 time zone (NEM time)
MEASUREMENT_DATETIME datetime(3) 🔑 datetime2(0) 🔑 Date and time of the SCADA data (DD/MM/YYYY HH24:MI:SS) fixed to the UTC+10 time zone (NEM time)
CONSTRAINTID varchar(20) 🔑 varchar(20) 🔑 Constraint ID (binding constraint ID from FCAS data used in FPP calculations)
VERSIONNO numeric(5, 0) 🔑 smallint 🔑 Version (FPP run number from the FPP database)
BIDTYPE varchar(10) varchar(10) Bid type (the bid type saved in relation to constraint ID from FCAS data used in FPP calculations)
FM_RAISE_HZ numeric(18, 8) numeric(18, 8) Calculated 4 second Frequency Measure in Hz for that constraint from the FPP database. Frequency Measure data is split across these two raise and lower columns in the following ways: >0 = Allocated to the FM_RAISE_HZ column <0 = Allocated to the FM_LOWER_HZ column 0 = To fill any gaps where the alternative column is not applicable (or no deviation from 50 Hz)
FM_LOWER_HZ numeric(18, 8) numeric(18, 8) Calculated 4 second Frequency Measure in Hz for that constraint from the FPP database. Frequency Measure data is split across these two raise and lower columns in the following ways: >0 = Allocated to the FM_RAISE_HZ column <0 = Allocated to the FM_LOWER_HZ column 0 = To fill any gaps where the alternative column is not applicable (or no deviation from 50 Hz)
USED_IN_RCR_FLAG numeric(5, 0) tinyint Flag to indicate the result of the Frequency Measure alignment check between Mainland and Tasmania for global constraints. Supported values are: 0 = Not used in RCR calculation as the signs for the frequency measures between Mainland and Tasmania do not align 1 = Used in the RCR calculation as the signs for the frequency measures between Mainland and Tasmania do align in the case of global constraints. For non-global constraints this flag is set to 1
CORRELATION_FLAG numeric(5, 0) tinyint Flag to indicate the result of the Frequency Measure correlation check between regions in the same constraint. Supported values are: 0 = Frequency measures in this constraint are not correlated (e.g. system separation between two regions) 1 = Frequency measures in this constraint are correlated
