Each US grid operator publishes its own queue, on its own counting basis. DC Hub shows them side by side, ISO by ISO, with the basis and the source date, and does not add them together. Large-load requests are a separate queue and are shown separately.
| ISO | Queue, GW | Projects | What is counted | Source date |
|---|---|---|---|---|
| ERCOT | 453.8 | 1,874ERCOT-published request count, same report as the GW | ERCOT's published active generation interconnection requests (ERCOT's own report: the GIS Summary or the Monthly Operational Overview, named in queued_generation_gw_source); separate from the large-load queue | Sep 30, 2026published report |
| PJM | 374.2 | 1,256Includes 62 suspended. The GW figure includes them too. | Active serial + Transition Cycle (TC1/TC2) + Cycle 1 generation requests, sum of MFO (maximum facility output, not firm MW capacity); excludes transmission-service requests, In Service and Withdrawn. Since 2026-10-20 this total includes PJM's Cycle 1 requests, which the serial export alone did not list (that is why it rose from ~135 GW); not a PJM refresh | Oct 27, 2026live feed, fetch date |
| MISO | 266.7+ 21.1 GW pending revision, reported separately | 1,183 | Active only, summer MW; excludes Done, Pending and Withdrawn | Oct 27, 2026live feed, fetch date |
| SPP | 186.3 | 999Includes 335 in commercial operation. The GW figure includes them too. | Active requests, max summer MW; excludes cessation | Oct 27, 2026live feed, fetch date |
| CAISO | 164.9 | 573 | Active only, Net MW to grid (Public Queue Report) + Cluster 15 and Cluster 16 requests (NET MW at POI); co-located hybrid projects counted once; excludes Completed (built) and Withdrawn. Since 2026-10-20 this total includes Clusters 15 and 16, which the Public Queue Report alone did not list (that is why it rose from ~74 GW) | Jul 16, 2026live feed, fetch date |
| ISO-NE | 11.1 | 45 | Status A (active), summer MW; net MW where summer is blank; excludes Completed (C) and Withdrawn (W) | Oct 27, 2026live feed, fetch date |
| NYISO | 10.0 | 169 | Active only, summer MW | Oct 27, 2026live feed, fetch date |
Figures are the ISO's active generation requests as that ISO counts them. They are not comparable one-for-one and are not summed. DC Hub checks each source daily; the source date is the date of the figure's own report or feed. The NESO, AESO, IESO connections queues count generation and demand projects in one figure; they are outside the US and are not shown here, but are in the API.
474 GW of large-load requests (June 2026 data) are waiting to connect to ERCOT. ERCOT states about 90% are data centers; DC Hub multiplies that out to 426.6 GW, a derived figure ERCOT does not publish itself. ERCOT source.
This is a demand queue. It is not added to any figure in the table above. The other ISOs' public queues are generation-side and do not classify load, so DC Hub carries no large-load figure for them.
Live from the Data Center Power Index, the same ranking the rank_markets tool serves:
markets with a BUILD verdict, highest composite first.
| Market | ISO | Verdict | DCPI, of 100 |
|---|---|---|---|
| Midland–Odessa, TX | ERCOT | BUILD | 80.6 |
| Upper Peninsula MI, MI | MISO | BUILD | 77.1 |
| Williston, ND, ND | MISO | BUILD | 76.9 |
| Rural SPP, KS | SPP | BUILD | 75.8 |
| Cheyenne, WY | WECC | BUILD | 74.8 |
| North Kansas City, MO | SPP | BUILD | 71.1 |
Scored daily, as of 2026-10-27. The verdict and composite are free; the sub-scores behind them need a key. All markets.
7 US ISOs publish an active generation queue: ERCOT 453.8 GW; PJM 374.2 GW; MISO 266.7 GW; SPP 186.3 GW; CAISO 164.9 GW; ISO-NE 11.1 GW; NYISO 10.0 GW. Each figure is that ISO's own, on its own counting basis and source date, so DC Hub shows them side by side and does not add them together.
No. A large-load (demand) queue is a different thing from a generation queue and is shown separately. DC Hub carries a large-load queue for ERCOT; the other ISOs' public queues are generation-side and do not classify load. ERCOT reports about 474 GW of large-load requests (June 2026 data).
A queue shows how much generation is waiting to connect to a grid, which bears on how soon and how cheaply new load can be served there. DC Hub's Data Center Power Index turns queue position, load growth and retiring capacity into a daily BUILD, CAUTION or AVOID verdict for each market.
DC Hub checks every source daily. Each ISO's figure carries its own source date, and ERCOT's generation figure comes from a monthly report.
