Residual Cashflow Reallocation Cashflow (RCRC)
Any money that you pay in Imbalance Charges is redistributed amongst all BSC Parties, on a scale proportional to your volume of credited energy. This redistribution is paid as Residual Cashflow Reallocation Cashflow (RCRC). RCRC data is presented on a £/MWh basis.
You can download RCRC data (in XLS format) and an explanation of how to use this data to calculate how much you will receive in RCRC payments (in PDF format) from the table below.

GSP Group Correction Factors (GGCFs)
GSP Group Correction Factors (GGCFs) are used to ensure that the total energy allocated to Suppliers in each Settlement Period in each GSP Group matches the energy entering the GSP Groups from the transmission system and through embedded generation. To achieve this, GGCFs are applied to the energy allocated to Suppliers from non-half-hourly metering systems.
You can use the files in the table below to get a detailed explanation of this calculation and to see a set of GSP Group Correction Factors for every Settlement Day in the year. There is one sheet per GSP Group.

Transmission Loss Multipliers (TLMs)
The Transmission Loss Multiplier (TLM) is applied to a BM Unit’s Metered Volume to adjust for Transmission Losses. Although TLMij is defined as a BM Unit-Settlement Period level variable, there are only two values for TLM per Settlement Period: one for BM Units belonging to Trading Units that are off-taking Trading Units in the Settlement Period, and one for BM Units belonging to Trading Units that are delivering Trading Units in the Settlement Period. This is because the Transmission Loss Factor (TLFij), used in the calculation of TLM, is zero for all BM Units. If you're interested in Transmission Loss Multipliers, you can download historic TLM data from the table below.
