U.S. power-plant and storage grid requests · Submitted 2000–2020 · Status at end of 2025
Share of 21,927 requests in the report’s outcome sample. Counts, not generating capacity.
15,515 requests
4,192 requests
1,921 requests
299 requests
Suspended means on hold. Withdrawn does not mean rejected by a grid operator; the data do not assign a reason for each withdrawal.
Most requests in this older cohort did not become operating power resources. By the end of 2025, 15,515 had been withdrawn, while 4,192 were operating. Another 2,220 were still active or suspended, even though every request had entered a queue at least five years earlier.
A grid queue records developers’ plans to connect equipment, not a stock of completed plants. These outcomes show why a large queue cannot be read as a promise of future electricity supply. They do not show how many withdrawals were caused by grid delays, financing, permitting or a change of plan.
MISO’s current proposal concerns a different side of the grid: connecting large electricity users. This chart instead follows generation and storage requests, using outcomes recorded before that October 2026 dispute.
More Detail, Sources and Data
Requests Are Not the Same as Plants or Megawatts
The denominator is the 21,927 requests in the report’s published outcome analysis, submitted from 2000 through 2020 inclusive. The report selects regions with comprehensive status information; this is not a census of every U.S. connection application. Load requests, distribution-connected systems and equipment behind a customer’s meter are outside this dataset’s scope.
Each request has equal weight. A large plant counts the same as a small one. The operating share is 19.1% by request count, not the report’s separate 13% capacity-weighted result. Active and suspended requests are not treated as permanent failures; this is a status snapshot, not a prediction for a new application.
| Status | Requests | Share |
|---|---|---|
| Withdrawn | 15,515 | 70.8% |
| Operating | 4,192 | 19.1% |
| Still active | 1,921 | 8.8% |
| Suspended | 299 | 1.4% |
| Total | 21,927 | 100% |
Source, Calculation and a Conflicting Footnote
Vastkind summed the 21 annual rows in the original workbook, sheet “23. Completion Rate Trend,” cells A28:E48. Each share equals its status count divided by 21,927, multiplied by 100. Bars use unrounded shares; labels use one decimal place, so displayed shares add to 100.1% after rounding.
The workbook tables and the figure on page 35 of the 2026 report support 21,927 requests. Footnote 5 on that page instead says 22,061. The source does not explain the difference. This chart uses the reproducible table total, not the conflicting footnote.
The publication catalogue and workbook are dated May 2026; the report cover is dated June 2026. The outcome snapshot ends in 2025.
