Stalled Interconnection Queue Projects: free sample (Tensorust LLC)

Every active generation request in six U.S. grid queues, with the ones that are stuck flagged and why.

Headline: Six grid operators (PJM, MISO, ERCOT, SPP, CAISO, NYISO) hold 6,904 active generation requests totaling 1,390.5 GW, and 2,570 of them (427.3 GW) are stuck by at least one rule: studies done with no agreement after 2+ years, an agreement signed but the online date slipped 2+ years or already passed, suspended, or 5+ years in queue with no agreement.

This repository is a free teaser, not the dataset. It holds 25 example rows and a summary table with no names in it. The full file has 6,904 rows and is sold by Tensorust LLC: https://tensorust.com/datasets/interconnection-queue-stalled/.

Method and limits

Download each operator's public queue file (PJM planning queue XML, MISO GI queue API, ERCOT GIS report, SPP active queue CSV, CAISO public queue report, NYISO queue workbook), keep active generation requests, map each operator's status fields to studies_complete, ia_executed, suspended and under_construction, compute years in queue and COD slip against the build date, set the four stall flags, and join developer names (published only by ERCOT and NYISO) to the Tensorust ontology. LBNL's Queued Up compilation sits behind an interactive challenge page, so the operator files are used directly.

Not every U.S. queue (ISO-NE and non-ISO utilities are not in it), not a forecast of withdrawals, and not developer data for PJM, MISO, SPP or CAISO (those operators do not publish it). Flag rates differ by operator because each publishes different fields: CAISO and MISO publish agreement status and online dates on nearly every project, PJM publishes queue age, so compare within an operator first.
