Allocation Round 4 update: Non-qualification review assessment window open

The non-qualification review assessment window is now open. National Grid ESO will assess any non-qualifying applications that were submitted for review by 25 March 2022.

National Grid ESO informed all Allocation Round 4 (AR4) applicants of the outcome of their application following the qualification assessment window, which concluded on 25 February 2022.

Between 28 February and 4 March 2022, any applicants that did not qualify could submit a request for National Grid ESO to review its decision.

National Grid ESO will review the relevant applications by 25 March 2022.

Once the non-qualification review assessment window is complete, any decisions that are upheld may be appealed. Applicants that remain non-qualifying following National Grid ESO’s determination may submit an appeal to Ofgem for a decision. Requests for appeals should be submitted from 28 March to 1 April 2022.

If the review finds that all relevant applications qualify for AR4, National Grid ESO will notify applicants whether an auction is required and, if so, invite the submission of sealed bids. This will happen by 5 April 2022 if all applications qualify following the review.

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). Note that a non-qualification review assessment window has been required, so timelines one and two in the table are no longer applicable for AR4.

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