Interconnection queue API overview

​

Available grid operators

​

Supported parameters

​

Core filtering parameters

• state - Filter by state code (e.g., CA, TX, NY) - supports comma-separated values
• technology - Filter by technology type (e.g., Solar, Wind, Battery) - supports comma-separated values
• status - Filter by project status (Operating, Planned, Cancelled, etc.)
• min_capacity - Minimum capacity in MW (numeric)
• max_capacity - Maximum capacity in MW (numeric)

​

Pagination parameters

• limit - Number of records per page (50-5000, default: 1000)
• offset - Number of records to skip (default: 0)

​

Parameter validation

• Supported parameters are processed and applied as filters
• Unknown parameters are rejected with a 400 Bad Request error
• Invalid values are rejected with clear error messages

​

Basic usage examples

# Get first 100 solar projects in California
GET /api/v1/interconnection/caiso?state=CA&technology=Solar&limit=100

# Get operating wind projects over 100 MW across multiple states  
GET /api/v1/interconnection/pjm?state=PA,OH,NJ&technology=Wind&status=Operating&min_capacity=100

# Get planned projects in Texas with pagination
GET /api/v1/interconnection/ercot?status=Planned&limit=500&offset=1000
