- [Processed CSV of every project row](https://www.ercotqueue.com/data/projects.csv)

## What the report contains

The workbook's project detail sheets, Large Gen and Small Gen, list each interconnection request by its INR number with fuel, capacity, county and zone, study and agreement milestones, and the projected commercial operation date. ERCOTQueue parses both sheets every month and keeps every report since December 2018.

The report records interconnection requests, not a supply forecast. Projects leave the queue every month.

ERCOTQueue distinguishes reported source fields from independently derived analysis. Queue capacity records development and interconnection activity; it does not establish financing, construction, or commercial operation. Build Chance is a research signal, not a guarantee or investment recommendation.
