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.

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.

Zone	Description	Primary Technologies
A	Western NY	Wind, Natural Gas
B	Genesee	Wind, Solar
C	Central NY	Wind, Solar
D	North NY	Wind, Hydro
E	Mohawk Valley	Solar, Natural Gas
F	Capital	Solar, Wind
G	Hudson Valley	Solar, Storage
H	Millwood	Solar, Storage
I	Dunwoodie	Solar, Storage
J	NYC	Solar, Storage, Natural Gas
K	Long Island	Solar, Storage, Wind (offshore)

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 Cancelled: Projects withdrawn from the queue, with withdrawal dates tracked for historical reference.
