Overview

The ERCOT interconnection queue endpoint provides access to real-time data from the Electric Reliability Council of Texas (ERCOT) interconnection queue, which serves most of Texas.

ERCOT Coverage: Contains 2,200+ projects primarily in Texas (99%). Top technologies: Solar (800+ projects), Wind (400+ projects), Battery Storage (350+ projects).

Hybrid Projects: ERCOT represents each technology component of hybrid projects (e.g., solar + storage) as separate rows in their Excel source files with different INR numbers. Our API maintains this structure. See our comprehensive guide on hybrid project handling for details.

Data Updates: ERCOT queue data is updated weekly. The API reflects the most recent Generation Interconnection Request (GIR) data available from ERCOT.

Unique Features: ERCOT data includes detailed point of interconnection information (poi_location) and congestion zone mapping (cdr_reporting_zone), making it excellent for grid analysis.

Missing Coordinates: ERCOT data does not include latitude/longitude coordinates. Use the county, poi_location, and cdr_reporting_zone fields for geographic analysis.
