Ofgem approved BSC Modification P458

Ofgem approved BSC Modification P458: Introducing Data Controller and Processor Obligations in the BSC for Market-wide Half Hourly Settlement Testing on 3 October 2023. The Modification came into effect on Monday 9 October 2023.

What is the significance of the P458 Modification?
Earlier this year, the BSC Panel highlighted the requirement for a more flexible and comprehensive approach to data handling in the Balancing & Settlement Code (BSC) for the purposes of MHHS testing. Data currently processed under the BSC is aggregated and is therefore not personal data. However, with the advent of MHHS testing, personal information sharing, specifically meter-level data, is now required.

The BSC has therefore undergone changes to allow the data sharing required for MHHS testing. Modification P458 brings the BSC in line with current data handling practices by introducing specific data processor and controller obligations that are similar to those in the Retail Energy Code (REC).
