Bar length is capacity requested that year; the colours split it into capacity that reached operation, withdrew, or is still in the queue.

Shares are of requested capacity inside the current filter. A narrow filter can rest on very few requests, so read the request count beside each share.
Method and limits
Each request is counted once, at the capacity and status the dataset records for it, and grouped by the year it was filed. Requests missing a region, resource type, filing year or capacity are left out: 692 of 38,201 requests. Recent filing years are unsettled, since requests filed in the last few years may still be built or withdrawn.
The dataset records outcomes and dates, not reasons. Nothing here says why a request withdrew, and a share computed over a handful of requests is a reading of those requests, not a rate to plan against. For the published tables and the time-to-build figures, see queue statistics; for cost figures, see interconnection costs.

Want this reading for your own point of interconnection?
Send the node and the market. We read the public queue record for it — what was filed, what was built, what withdrew and how long each took — and send back what the record does and does not show.
