Overview
The NYISO interconnection queue endpoint provides access to real-time data from the New York Independent System Operator (NYISO) interconnection queue. NYISO serves all of New York State.NYISO Coverage: Contains 400+ projects across New York State. Top technologies: Solar (150+ projects), Wind (100+ projects), Battery Storage (80+ projects), Natural Gas (70+ projects).

Response Schema
Complete Upstream Data: Each project includes all 38 database columns from NYISO’s interconnection queue at the top level. This provides complete transparency with both standardized fields (normalized across all ISOs) and NYISO-specific raw fields like
queue_pos, energy_storage_capability, and minimum_duration_full_discharge.Response Fields
Core Identification
Capacity & Technology
Energy Storage Fields
Project Status & Dates
Location
Study Process & Interconnection
Grid Connection
Developer Information
Data Updates: NYISO queue data is updated based on NYISO’s interconnection queue reports.
NYISO Queue Terminology
Load Zones (A-K)
NYISO divides New York State into 11 geographic load zones that reflect transmission constraints and local electricity market conditions. Each zone represents a specific region with distinct pricing and capacity characteristics.Study Process Phases
NYISO projects progress through a multi-phase study process to assess technical feasibility and interconnection costs. FES (Feasibility Study): Initial technical and cost assessment to identify major system impacts and preliminary cost estimates. SRIS (System Reliability Impact Study): Detailed reliability analysis to determine required network upgrades for system reliability. This is the standard study path for most projects. SIS (System Impact Study): Alternative streamlined study path available for smaller projects with minimal system impact. FS (Facilities Study): Final engineering and cost estimates for required interconnection facilities and network upgrades.Queue Positions
Projects are assigned numeric queue positions (e.g., “0495”, “0522”, “1721”) when their interconnection request application is accepted as complete by NYISO. Lower numbers indicate earlier queue entry.Status Types
Planned: Active projects progressing through studies or awaiting construction. Includes statuses like “SRIS/SIS in Progress”, “IA Completed”, and “Accepted Cost Allocation”. Operating: Projects that have achieved commercial operation, marked as “In Service Commercial” in NYISO data. Cancelled: Projects withdrawn from the queue, with withdrawal dates tracked for historical reference.Technology Codes
NYISO uses single-letter or two-letter codes for technology types: “S” (Solar), “ES” (Energy Storage), “NG” (Natural Gas), “W” (Wind), “F” (Flywheel), “DC” (DC Transmission), “AC” (AC Transmission), “L” (Load/Data Center).Storage Duration
For battery storage projects, theminimum_duration_full_discharge field indicates how many hours the system can discharge at full rated capacity. Common values are “2.0”, “4.0”, or “8.0” hours.Authorizations
