The queue record

Every interconnection request the dataset records at this point of interconnection, in filing order.

Interconnection requests recorded at this point of interconnection, with request date, capacity and outcome.

What the record shows

  • 7,675 MW of the 9,076 MW filed here withdrew.
  • The largest request filed here, 1,434 MW (battery + storage), withdrew 4.3 years after filing.
  • Three requests were filed on 2023-04-17; 2 withdrew and 1 remains active.
  • Two of the 6 withdrawals came within a year of filing.
  • By technology, the requests here were solar + battery 4, battery + storage 2, storage 2, battery 1, solar 1.
  • The longest-standing active request here was filed on 2019-04-15.
  • The dataset records this point of interconnection under four spellings, which are combined here.

What a decision record would have to make explicit

  • None of the resolved requests at this node reached operation, and the public record does not say why.
  • Four requests are unresolved, so the outcome counts at this node can still change.
  • The dataset records outcomes and dates, not reasons, so no cause is attributed to any outcome here.

What this does and does not show

This is a reading of a public dataset, not a customer case study: no engagement, customer or client is involved. The dataset records outcomes — what was built, what withdrew, and when — but not why any project withdrew, so no cause is attributed here. Nothing on this page claims GridVision predicted, influenced or would have changed any outcome, and a pattern at one point of interconnection does not generalise to another.
