What the record shows
- 1,620 MW of the 2,418 MW filed here withdrew.
- The largest request filed here, 525 MW (solar), withdrew 4.0 years after filing.
- Five requests were filed on 2018-11-21; 4 withdrew and 1 remains active.
- One of the 7 withdrawals came within a year of filing.
- By technology, the requests here were solar 4, wind 4, battery 1, gas 1.
- The longest-standing active request here was filed on 2017-11-29.
- 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.
- Three 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.
