Queue Cluster Study
A queue cluster study groups multiple interconnection requests within the same electrical region into a single system impact study. Cluster studies evaluate shared network upgrades, spreading costs among participants and accelerating processing compared with sequential studies.
ISOs define cluster windows, deposit requirements, and withdrawal penalties that maintain discipline. Studies produce upgrade scopes, cost allocations, and deliverability assessments for all projects in the cluster.
Cluster reforms aim to reduce speculative requests, increase transparency, and align transmission planning with actual development interest. Developers must meet readiness milestones to avoid forfeiting deposits.
Investors assess cluster timelines and attrition rates when valuing queue positions.
Technical Details
- •Aggregates interconnection requests by region and study cycle
- •Generates shared upgrade cost allocation and deliverability results
- •Requires readiness milestones and withdrawal penalties
- •Aligned with FERC Order 2023 reforms
- •Often leads to queue-wide transmission planning initiatives
Why It Matters
Cluster studies determine upgrade costs and schedules for entire cohorts of projects. Tera links cluster data, sponsor readiness, and upgrade progress so users can benchmark interconnection risk.
