FAQs
What the scores do, and what they don't.
Short answers on the queue, the model, and how to read withdrawal-adjusted capacity.
- What is the interconnection queue?
- The interconnection queue is the backlog of generation and storage projects waiting to connect to the electric grid. Each ISO and RTO maintains its own queue. Projects must complete feasibility, system impact, and facility studies before they can operate. Most proposed capacity in U.S. interconnection queues never reaches commercial operation.
- What is interconnection queue prediction?
- Interconnection queue prediction estimates which active queue projects are likely to withdraw before reaching commercial operation. GridSolve uses a Cox survival model trained on historical interconnection projects to assign withdrawal probabilities based on cluster studies, technology, service type, and queue position — then discounts substation capacity by expected withdrawals.
- How does GridSolve help data center developers?
- Data center developers need to know where grid power is realistically available, not just what hosting-capacity maps claim. GridSolve re-scores 4,600+ U.S. substations by withdrawal-adjusted deliverable megawatts — capacity that remains after likely queue withdrawals — so developers can prioritize sites with real interconnection headroom.
- Does GridSolve predict data center interconnection requests?
- GridSolve models generation-interconnection queue projects (solar, wind, storage, and similar), not large-load or data-center interconnection requests, which follow separate utility tariffs. Deliverable capacity per substation is a proxy for where grid headroom is likely to exist — not a load interconnection study.
- What is withdrawal-adjusted interconnection capacity?
- Withdrawal-adjusted capacity is the megawatts at a substation that are likely to remain deliverable after speculative queue projects withdraw. GridSolve subtracts each active project's predicted withdrawal share from queued megawatts to produce adjusted available capacity — a more realistic view than raw hosting-capacity figures.
- What data sources does GridSolve use?
- GridSolve combines ISO/RTO interconnection queue data from Lawrence Berkeley National Laboratory's Queued Up dataset with LBNL interconnection cost studies. Withdrawal rates are computed empirically within each region from resolved projects; the survival model validates against regional concordance metrics.
