Gate 2 in the transmission queueHow much of the queue has a Gate 2 offer, and what it did to connection dates. The battery queue and CMP470’s commitment feeHow far the battery queue sits above the line that would switch CMP470’s commitment fee off. Changes of customer in the transmission queueHow often connection agreements move between companies, and how those projects fared. Do projects connect on time?How late stages have connected against their connection date in the register. Which connection dates slip least?Which connection dates are pushed back least, allowing for how far ahead they are.

Status definitions (NESO)

Scoping: NESO is not aware that a planning application has been made.

Awaiting Consents: NESO is aware, or the customer has told it, that a planning application has been made.

Consents Approved: NESO is aware, or the customer has told it, that the planning application has been approved.

Terminated: used by NESO only in its register of 30 April 2021, for two projects that left the register the next month.

These statuses are NESO’s, not QueueWatch’s, and NESO describes them as “as far as we are aware”, so a project may be further along than its status shows.
