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

What the record shows
- 2,354 MW of the 2,504 MW filed here withdrew.
- The largest request filed here, 500 MW (solar), withdrew 2.5 years after filing.
- Four requests were filed on 2023-10-02; all of them withdrew.
- Six of the 8 withdrawals came within a year of filing.
- By technology, the requests here were wind 6, solar 3.
- The longest-standing active request here was filed on 2021-04-20.
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.
- One request is 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.
