Connection queues and waits: 38 markets, worst first

Queue context: These are generation and storage interconnection queues. They show how congested the interconnection system is. They do not measure how long a new large load waits, and their withdrawal rates are not load withdrawal rates. At the end of 2025, generation and storage projects totalling about 2,060 GW were actively waiting in United States queues, down 10% from a year earlier. Of the capacity that entered between 2000 and 2020, about 75% withdrew before connecting and only about 13% reached operation by end-2025. The typical project built in 2025 waited about 61 months from request to operation (Lawrence Berkeley National Laboratory, Queued Up 2026). Figures below are refreshed quarterly; each is labelled measured or modelled.

The wait is the typical end-to-end time for a large new load, from a complete application being accepted to full firm energization of the nominated MW, not a firm quote. Earlier milestones (initial, phased, temporary or conditional energization) come sooner and are reported separately. Multi-year waits are real in saturated grids: in Northern Virginia, Dominion has said large data centres over 100 MW can wait up to seven years, and parts of the Netherlands and Ireland are quoted at similar or longer horizons.
