There is a conflict between the rules in the Balance and Settlement Code (BSC) and the Capacity Market (CM) rules regarding how Balancing Mechanism (BM) Units are registered. Removing this conflict from the BSC will clarify the arrangements and ensure BSC Parties remain compliant with both the BSC and CM rules.


P389 was raised on 1 August 2019 with a recommendation to go straight to Report Phase. The Initial Written Assessment was presented to the Panel on 8 August 2019. The Panel agreed that P389 should proceed to the Report Phase and initially recommended that P389 be approved.

The Report Phase Consultation was issued on 9 August until Friday 23 August 2019 (see below). There were no responses to the consultation.

The Panel approved P389 as a Self-governance Modification on 12 September 2019.
