# ERCOT System Map

Interactive map of ERCOT generation queue capacity, build probability, COD delay concentration, county boundaries, and public large-load evidence with explicit source and geometry precision.

## Scope and precision

- Generation projects are aggregated to county-level geography.
- County shapes are official boundaries.
- County-center symbols are not exact project locations.
- Historical comparison records changes between public monthly reports.
- A project disappearing from a report does not independently prove cancellation.

## Historical coverage

- Earliest report: 2018-12
- Latest report: 2026-07
- Monthly observations: 92

## Data

- [Current county generation GeoJSON](https://www.ercotqueue.com/data/system-map/county_generation.geojson)
- [Texas county boundaries](https://www.ercotqueue.com/data/system-map/texas_counties.geojson)
- [Historical manifest](https://www.ercotqueue.com/data/system-map/history/manifest.json)

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.
