Get ERCOT interconnection queue data

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.

Endpoint

Query Parameters

Technology Options

Use standardized technology names. See our Interconnection Reference for all available options.

Status Options

Example Requests

Returns active solar projects in the ERCOT queue. Uses technology=Solar for standardized filtering.
Finds large-scale wind projects. Uses technology=Wind for wind turbine projects.
Filters for battery energy storage projects.
Uses comma-separated values for multiple technology filtering.

Response Schema

Complete Upstream Data: Each project includes all 49 database columns from ERCOT’s interconnection queue at the top level. This provides complete transparency with both standardized fields (normalized across all ISOs) and ERCOT-specific raw fields like inr_request_number, screening_study_required, and planned_outage_season.

Developer Information

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.
