P483 Allow Asset Metering Systems to be used in Settlement where the associated Boundary Point Metering System is Non-Half Hourly
Formal title: Allow Asset Metering Systems to be used in Settlement where the associated Boundary Point Metering System is Non-Half Hourly
The implementation of BSC Modification P375 ‘Settlement of Secondary BM Units using metering behind the site Boundary Point’ allows Asset Metering System Identifier (AMSID) Pairs to participate in Settlement by utilising metering situated behind the Boundary Point. However, it requires that the associated MSID Pair—the Boundary Point Metering System—must be settled Half-Hourly. This requirement prevents most domestic consumers from participating in flexibility services with smart devices, as the majority are not half-hourly settled, and consumers, along with their Virtual Lead Parties (VLPs), cannot mandate changes to the meter’s Measurement Class.
This Modification seeks to address this issue by removing the Half-Hourly settlement requirement for associated Boundary Point Metering Systems. Doing so will expand access to flexibility markets for domestic consumers, support equitable participation in energy services, and reduce the dependency on Market-wide Half-Hourly Settlement (MHHS) for consumer inclusion. This change is expected to enable flexible asset participation and support energy system goals such as Clean Power 2030.
