P421 Revised Implementation Date Consultation

At the Panel meeting on 9 December 2021, Ofgem noted that there was a risk that they will be unable to make a decision on P421 by 3 February 2021, which is required to meet the standard February 2022 Release. Were this to happen, P421 would ‘time-out’ and be closed.

To mitigate this risk the Panel requested a revised Implementation Date for P421 (in accordance with Section F2.11.18).


Who will this impact?

The Panel is recommending that the Implementation Date is amended to the following:

  • 24 February 2022, if the Authority’s decision is received after 28 October 2021 but before 3 February 2022; or
  • Five Working Days (+5WDs) following the Authority’s decision, but no earlier than 3 March 2022, if the decision is received after 3 February 2022
    • Please note if a decision is received after the 3 February 2022 but before the 3 March 2022 we will treat this for the purposes of implementation of having been received on the 3 March 2022 (to avoid conflicting with the standard February 2022 Release).

It is the second bullet to the P421 Implementation approach that is new i.e. +5WDs after decision.

The Panel has recommend that P421 is approved. It has been submitted to Ofgem for decision as it impacts the EBGL balancing terms and conditions.
