GSP Group Correction Factors data from the Trading Operations Report
The page below details highlighted GSP Group Correction Factors (GGCFs) data from the previous month. This data is acquired from BSC Agents and inputted to the Trading Operation Monitoring Analysis System (TOMAS) database.

Distribution of Half-Hour GGCFs across all GSP Groups
The chart below shows the distribution of GGCFs, as per the latest Settlement Run data, for each Settlement Period in the last complete month against the previous three years. Again it shows the effectiveness of profiling, with the ideal being a narrow distribution centred on 1.
Highlights
There are no major updates.
Half-Hour Correction factors by Settlement Period volume
The following is based on Initial Settlement (SF) Run for the latest month and is weighted across all GSP Groups.
The chart below shows, for each of the day types used in profiling, a volume weighted average, such as adjusted to reflect the relative sizes of each GSP Group (in terms of total daily energy consumption), of the GGCFs across all GSP Groups by Settlement Period.
The source data are GGCFs from the Initial Settlement (SF) Run taken over the latest month for which SF data is available. The average is taken, for each Settlement Period, over the one month interval to create plots of volume-weighted GGCFs for the periods from Monday to Friday, for Saturdays and for Sundays included in the data set. It allows comparison of profiling for different day types and shows intra-day profiling effects.
Anything between 0.9 and 1.1 is considered reasonable. Values outside this range may indicate issues with load profiling or metering data.
Highlights
There have been higher threshold breaches in the latter half of the day over the month due to the increase in profiled NHH Import estimation under reporting consumption. This is particularly prevalent in GSP Groups _A, _H, _G, _M and _N.
Daily Average GSP Group Correction Factor by GSP Group
The chart below is based on the latest Settlement Run for the last year.
This chart shows the daily average GGCF using the latest Settlement Run data for each GSP Group for the last year. It shows both profiling and metering effects, as per the earlier explanation on the effects of profiling and metered volumes.
Highlights
There are increases in GCF across all GSP Groups on New Years Day which could be genuine however, this is currently under investigation to determine the route cause.
