Interconnection queue data for seven US grid operators
FieldProspects combines the planned projects of seven US grid operators, ERCOT, PJM, MISO, CAISO, NYISO, ISO-NE and SPP, into one table. Together they hold 7,491 planned units totaling 1,470.8 GW. ERCOT is the largest, with 2,359 units and 532.2 GW. Figures are as of October 2026.

What the combined queue table contains
Each of the seven grid operators publishes its own queue. The queue table puts their planned projects on one footing, so ERCOT and MISO can be compared unit for unit. Of the 7,491 planned units, 5,726 come from the operators' own queue extracts and 1,765 come from the planned generator list in EIA Form EIA-860M that falls inside the same grid.
Rows carry a planned status only. They do not carry a study stage, so the table cannot say where in an operator's process a project stands. What it does carry is capacity, technology, state, expected in-service year and, where the source gives one, a developer. That last field varies widely by grid: NYISO attributes a developer to 92.8% of its planned units and MISO to 32.8%.
A unit is a generating unit, not a plant, and a project that is split across units or phases can appear more than once. This page publishes totals only. No project names, dates of individual requests or coordinates appear here.
Planned capacity in each grid operator queue
| Grid operator | Planned units | Planned capacity | Units from the queue extract | With a developer |
|---|---|---|---|---|
| ERCOT | 2,359 | 532.2 GW | 1,835 | 70.7% |
| MISO | 1,684 | 301.4 GW | 1,357 | 32.8% |
| PJM | 1,492 | 260.3 GW | 1,109 | 36% |
| CAISO | 780 | 186.2 GW | 562 | 42.2% |
| SPP | 669 | 129.4 GW | 559 | 42.9% |
| NYISO | 376 | 44.4 GW | 238 | 92.8% |
| ISO-NE | 131 | 16.9 GW | 66 | 71% |
Units not in the queue extract come from EIA-860M. The seven grids hold 7,491 of the database's planned units.
What the seven queues are made of
| Technology | Units | Capacity | Share of capacity |
|---|---|---|---|
| Solar | 3,221 | 534.1 GW | 36.3% |
| Battery Storage | 2,321 | 414.9 GW | 28.2% |
| Natural Gas | 748 | 259.3 GW | 17.6% |
| Wind | 599 | 154 GW | 10.5% |
| Solar + Storage (Hybrid) | 263 | 46.1 GW | 3.1% |
| Nuclear | 19 | 28.7 GW | 2% |
| 17 other technologies | 320 | 33.7 GW | 2.3% |
When queue capacity is expected to be in service
| Expected year | Units | Capacity | Share of capacity |
|---|---|---|---|
| 2026 | 1,126 | 140.8 GW | 9.6% |
| 2027 | 1,479 | 242.6 GW | 16.5% |
| 2028 | 1,560 | 337 GW | 22.9% |
| 2029 | 992 | 234.2 GW | 15.9% |
| 2030 | 624 | 162.3 GW | 11% |
| 2031 | 190 | 63.8 GW | 4.3% |
| 2032 and later | 88 | 50.2 GW | 3.4% |
| Year before 2026, still listed as planned | 1,079 | 161.9 GW | 11% |
| No expected year listed | 353 | 78.1 GW | 5.3% |
The year is the expectation given by the source for each unit, not a commitment.
What is an interconnection queue?
An interconnection queue is the list a grid operator keeps of the generation and storage projects that have asked to connect to its transmission system.
What approved accounts can do with the queue
Approved accounts search the full queue across all grids, filter by state, grid, developer, capacity, county and year, sort by request date and export the filtered result. The seven-day trial covers all five tables and allows an export of up to 250 rows.
