The queue record
Every interconnection request the dataset records at this point of interconnection, in filing order.
This page reads 13 dataset rows at every MISO request in Madison County, Mississippi whose utility the dataset records as Entergy, recorded under ten point-of-interconnection names. None of those points has enough requests for a page of its own, so they are read together. Two further Madison County rows that do not name Entergy as the utility are not included.

What the record shows
- 906 MW of the 1,683 MW filed here withdrew, and 100 MW reached commercial operation.
- The one request that reached operation took 4.4 years from request to commercial operation.
- The largest request filed here, 200 MW (solar), withdrew 2.9 years after filing.
- Five requests were filed on 2022-09-15; 2 withdrew and 3 remain active.
- None of the 7 withdrawals came within a year of filing; the quickest took 1.0 years.
- By technology, the requests here were solar 10, battery 2, solar + battery 1.
- The longest-standing active request here was filed on 2020-06-23.
What a decision record would have to make explicit
- What separated the requests that reached operation from those that withdrew, such as study results, upgrade assignments or site conditions, is not in the public queue record, so a decision record here would have to carry it as an unknown.
- Five 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.
