The Two Queues: Interconnection Pressure by ISO
The grid has two interconnection bottlenecks, not one — a supply queue of power plants and a fast-growing demand queue of data centers. A scorecard of where each is most likely to stall, and where capacity clears fastest.
What this report covers
- Queue depth and study backlog by ISO/RTO
- Large-load request treatment and reform proposals
- Where capacity clears fastest
- Implications for siting decisions
