The appeals submission window is now open and will close on 1 April 2022 at 5pm.

National Grid ESO informed relevant Allocation Round 4 (AR4) applicants of the outcome of their non-qualification review result on 25 March 2022.

Applicants that remain non-qualifying following National Grid ESO’s determination may submit an appeal to Ofgem for reconsideration. Requests for appeals may be submitted from 28 March to 1 April 2022.

If any appeals are submitted during this window, Ofgem will consider them between 12 April and 12 May 2022.

For further information on the various stages of the round, see this table setting out the original five potential timeline scenarios for AR4 (PDF, 94KB). Please note that following the opening of the appeals submission window, timelines one–three in the table are no longer applicable for AR4.

Further updates on AR4 will be published on this website as the round progresses.
