Overview
The SPP interconnection queue endpoint provides access to real-time data from Southwest Power Pool’s interconnection queue. SPP serves the central United States with significant wind resources.SPP Coverage: Contains 800+ projects across the central U.S. Top technologies: Wind (400+ projects), Solar (200+ projects), Battery Storage (100+ projects), Natural Gas (100+ projects).

SPP Queue Terminology
DISIS (Definitive Interconnection System Impact Study)
SPP’s cluster study process where projects are studied in annual cohorts grouped by transmission zone. Projects are studied together to assess cumulative system impacts and allocate network upgrade costs equitably among projects in each cluster.Cluster Groups
SPP divides its territory into transmission zones (e.g., “04 SOUTHEAST”, “03 CENTRAL”) for organizing DISIS cluster studies. Each annual DISIS cohort (e.g., “DISIS-2011-001”) contains projects grouped by these zones for efficient regional analysis.Service Types
- ER (Energy Resource): Energy-only interconnection without transmission network upgrade obligations
- NR (Network Resource): Full network service requiring participation in network upgrade costs and providing firm transmission capacity
- ER/NR: Hybrid service combining both energy resource and network resource interconnection rights
JTIQ (Joint Targeted Interconnection Queue)
Coordinated interconnection study process for projects located at the SPP/MISO seam requiring joint analysis by both ISOs to assess impacts on both systems.Generation Interconnection Agreement (GIA)
Final contract between generator and SPP governing interconnection terms, cost allocation, operational requirements, and construction milestones.Status Categories
SPP tracks detailed project status through multiple study phases:- IA FULLY EXECUTED/ON SCHEDULE: Interconnection Agreement signed and project on schedule
- IA FULLY EXECUTED/COMMERCIAL OPERATION: Project has achieved commercial operation
- IA FULLY EXECUTED/ON SUSPENSION: Agreement executed but study process suspended
- IA PENDING: Interconnection Agreement pending execution
- DISIS STAGE: In Definitive Interconnection System Impact Study phase
- FACILITY STUDY STAGE: In Facilities Study phase evaluating specific interconnection facilities
- FEASIBILITY: In Feasibility Study phase
- ERAS: In Early Risk Assessment Study phase (optional pre-study)
- WITHDRAWN: Project withdrawn from queue by developer
- TERMINATED: Project terminated by SPP
Data Updates: SPP queue data is updated based on Southwest Power Pool’s Generation Interconnection queue reports.
