P399 – BSAD Identity Visibility

Formal title: Making the identity of Balancing Service providers visible in the Balancing Services Adjustment Data

Current Status

Initial Written Assessment

Report Phase
With Authority
Awaiting Implementation


P399 seeks to include a new identifier field in the Balancing Services Adjustment Data (BSAD).

Currently, each Balancing Adjustment Action taken outside the Balancing Mechanism is reported with a unique sequential number. The Proposer contends that this does not identify the counterparty to the bilateral trade and creates an information advantage to those counterparties, reducing transparency in the operation of the system creating a barrier to effective competition.


This Modification was raised on Tuesday 24 December 2019 and the Initial Written Assessment was presented to the Panel on 16 January 2020.
