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

What the record shows
- Three of the nine requests at this node withdrew, and 1,429 MW of the 1,598 MW filed here never reached operation.
- The one project that reached operation, 169 MW of solar + battery, took 7.6 years from request to commercial operation.
- Two requests were filed on 2013-04-30, and all of them withdrew.
- Three technologies were filed here: Geothermal, Solar and solar + battery.
- Five of the nine requests were still active at the end of the dataset, so this node's record is not settled.
What a decision record would have to make explicit
- A pattern across nine requests at one node is an observation about this node, not a rate that transfers elsewhere.
- Five requests are 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.
