It is used because it publishes withdrawn and completed projects, not just the live queue — which is what makes attrition and these durations computable without years of our own snapshots. It is not a national figure.","A completed interconnection request means an executed agreement, not a power plant. Roughly half of completed projects have not started construction, so the agreement clock and the energization clock are reported as two separate numbers and must never be merged.","The agreement duration counts completed projects only, in queue-entry cohorts at least 90% resolved. Recent cohorts are excluded on purpose: they are mostly still in progress, so the only ones that have finished are the fast ones, and including them makes interconnection look like it is accelerating when it is not.","The inService field is populated for active projects too, where it is a projected date rather than a realized one. Only completed projects contribute to a realized figure.","FERC Order 2023 moved interconnection study from serial to cluster processing, and MISO re-sequenced its queue accordingly. Counts of queue entries are not comparable in the same units across that transition.","Megawatts are summer net capacity as filed. A project can be revised or re-filed, so queue MW is a measure of requests, never of plant that will exist."],"via":"api-fresh"}
