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

What the record shows
- Six of the eight requests at this node withdrew, and 1,786 MW of the 2,192 MW filed here never reached operation.
- The one project that reached operation, 405.85 MW of battery, took 8 years from request to commercial operation.
- The largest request ever filed here, 510 MW, withdrew 1.1 years after filing.
- Two requests were filed on 2019-04-15, and all of them withdrew.
- Four technologies were filed here: Solar, Battery, Solar + battery and solar + wind + battery.
What a decision record would have to make explicit
- A pattern across eight requests at one node is an observation about this node, not a rate that transfers elsewhere.
- One request is unresolved, so any comparison at this node has to stay open rather than concluded.
- The dataset records no withdrawal reasons, study costs or upgrade assignments, so those remain unknowns on this record.
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.
