Each bar sums one kind of evidence across facilities. Announced is the largest MW a company, utility, government or press source reported. Interconnection requests are MW in active large-load queue requests. Of the grid operators we ingest, only NYISO publishes these project by project. Contracted / approved means an executed interconnection agreement or a reported utility or power contract. Under construction and Operational come from construction records, imagery or operator reports.

The gap between announced and documented MW is capacity that has been claimed but not yet backed by a grid, construction or operating record. It is not proof a project won't happen. On-site generation is listed separately and never added to grid capacity. Method

Time to power puts each site's pending MW (announced minus operational) into a bucket by the midpoint of its evidence-based window. The window starts at the furthest documented stage and adds editorial ranges for what remains (e.g. announced: 2–5 yrs; land acquired: 2–4.5 yrs; planning / zoning: 1.75–4 yrs). Insufficient evidence means no dated stage evidence, not a delay. Windows are ranges, not forecasts. All ranges and rules

A queue request asks a grid operator (ISO/RTO) to connect a new generator or large load to the transmission system. It then moves through studies (feasibility, system impact, facilities) before an interconnection agreement, construction and service. Filing is an application, not a commitment to build. Generation totals here are active requests only.

Why most aren't built: in the queue files we ingest, no grid operator in this scope publishes its withdrawn requests. These are shares of each published file, not completion rates. CAISO is left out because their files don't include withdrawn requests. Queue sources

Data-center load requests are shown only where an ISO publishes them project by project (NYISO). Elsewhere, large loads go through utilities, and the ISO figures above (e.g. ERCOT's large-load tracking) are quoted from the operator's own documents.
