What the record shows

  • 6,910 MW of the 7,535 MW filed here withdrew.
  • The largest request filed here, 1,150 MW (solar), withdrew 0.5 years after filing.
  • Five requests were filed on 2023-04-17; 3 withdrew and 2 remain active.
  • Five of the 14 withdrawals came within a year of filing.
  • By technology, the requests here were solar 9, solar + battery 3, battery 2, wind 2, solar + wind 1.
  • The longest-standing active request here was filed on 2021-04-15.
  • The dataset records this point of interconnection under seven 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.
