BSC Insights: How we use the Annual Demand Ratio to maintain accuracy of Settlement data
In this insight article Mehdi Jafari and Jason Jackson explain what the Annual Demand Ratio (ADR) is, how it helps us maintain the accuracy of Settlement data, and what we are doing to resolve potential errors indicated by the ADR.
Update on investigations into Settlement errors at two GSP groups
Elexon has been investigating errors in Settlement related to two Grid Supply Point (GSP) Groups: South Eastern GSP Group (Group _J); and London GSP Group (Group _C). This follows our continued monitoring of the Annual Demand Ratio (ADR).
How we’re helping to spot GSP metering errors sooner
In the past eight years, we have identified five Grid Supply Point (GSP) Metering errors, equal to around 1.4% of the total number of GSP Meters. These errors have caused energy to be recorded incorrectly. As any unaccounted energy is allocated to BSC Parties through GSP Group Correction and Transmission Losses, such metering errors can present a large impact on the allocation of energy and therefore the accuracy of Trading Charges to BSC Parties.
We are publishing a beta version of our GSP change-point detection model to gather feedback from participants and help us identify other areas where central analytics and reporting could support industry in mitigating risks to Settlement.
