What share of interconnection requests are actually built?

Of the 39,346 interconnection requests on file across the 56 US queues Watt Street tracks, 4,902 have been built and 26,064 withdrawn — a build rate of 15.8% on decided applications, as of 14 October 2026. A further 7,747 are still waiting.

Answered from Watt Street’s own dataset — 39,346 interconnection requests across 56 US queues, data as of 14 October 2026. Method.

Why so many withdraw

A withdrawal is usually not a failure of the grid. Developers file on several sites to price them, keep the best and drop the rest — the queue is partly a price discovery mechanism. But withdrawals are not free to everyone else: each one can trigger a restudy for the projects behind it.

Reading a build rate honestly

The denominator matters. A request still waiting has not failed yet, so the honest rate is built divided by decided — built plus withdrawn — not built divided by everything ever filed.
