# Interconnection Queues

> US interconnection queues held 2,061 GW of proposed generation and storage at year-end 2025. Completed projects took a median 60.8 months from request to operation in 2025. Berkeley Lab’s sample excludes large loads; the tracker reports those separately, alongside resource MW, historical outcomes and dated reform milestones.

Queue MW, measured waits and the people who get projects onto the grid. 49 listings, each field linked to its public source, last verified 2026-11-11.
