Awaiting Implementation


P375 proposes using Metering Equipment ‘behind’ the defined Boundary Point for Balancing Services (‘behind the Meter’), for Settlement purposes rather than the Boundary Point Meter.

This will allow balancing-related services on-site to be separated from imbalance-related activities, more accurately reflecting the balancing-energy volumes provided by the Balancing Service Provider (BSP).

P375 arose from Issue 70 ‘Settlement of Secondary BM Units using metering at the asset’.


The sixth Workgroup meeting was on 6 November 2019 – the summary note is below.
