Table: SETIRSURPLUS

SETIRSURPLUS

Name

SETIRSURPLUS

Comment

SETIRSURPLUS records the interregional residue calculation for each interconnector and each side of the interconnector.


Description

SETIRSURPLUS data is public, so is available to all participants.

Source

SETIRSURPLUS updates once a day at 8am.

Note

MWFLOW and LOSSFACTOR are now both calculated as MWh (energy) values for the half hour, and not MW (average demand) values. By way of clarification, the MWFLOW value is derived from half-hour revenue class metering, adjusted by a fixed fraction of the LOSSFACTOR value. The LOSSFACTOR value is taken to be exactly half of the MWLOSSES value in the TRADINGINTERCONNECT table.

The METEREDMWFLOW field in the TRADINGINTERCONNECT table contains averaged SCADA metering demand values available in “real time”, whereas the MWFLOW field in the SETIRSURPLUS table contains settlement energy metering values available only after a settlement run is posted.
