The nominated Main Metered Data from the Primary Outstation validates satisfactorily (i.e. is ‘A’ flagged)

Validated Primary Outstation Main Metered Data is used for settlement, irrespective of data which may be missing or incorrect in the Secondary Outstation. This also covers sites that have only one Outstation under a dispensation.

2

The Main Metered Data from the Primary Outstation is either missing or fails validation but three out of four possible metered values (Main and Check meters in each Outstation) validate satisfactorily and agree with the other value from the precedent Outstation.

Data will be copied from the Main Meter from the Secondary Outstation and used in Settlement. This will be carried out automatically. The relevant BSC Party will be notified but their agreement will not be sought.

3

The Primary Outstation Data is either missing or incorrect, but the Secondary Main and Check validates satisfactorily.

Data will be copied from the Main Meter from the Secondary Outstation and used in Settlement. This will be carried out automatically. The relevant BSC Party will be notified but their agreement will not be sought.

4

The Main Metered Data is missing or incorrect in both Outstations, but the Check Metered Data in each Outstation validates against each other.

A Data Substitution will be performed using the Check Metered Data. Agreement to use this data will be sought from the relevant BSC Party and the data will be flagged as ‘estimated’.

5

The Main Metered Data is missing or incorrect in both Outstations, and the Check Metered Data in each Outstation does not validate satisfactorily.

A data estimation will be carried out using the Check Metered Data. Agreement to use this data will be sought from the relevant BSC Party and the data will be flagged as ‘estimated’.

Non Owner Party

A Non Owner Party is a Party to the BSC whose metered data is determined from a meter that is not registered by that Party.

Where there is a difference metering arrangement where a Party’s data is calculated by a netting relationship, the Party should receive data for the minority circuit which is netted off their data. This type of relationship is generally where there is shared, bulk supply point metering, inter GSP Group circuits and embedded Generating Plants.
