US planned power projects database
The FieldProspects planned power projects database holds 8,057 planned generating units in 51 states, totaling 1,547.4 GW of proposed capacity. Solar (568.6 GW) and Battery Storage (435.8 GW) lead by capacity. A developer is attributed to 50.8% of the units. Figures are as of October 2026.
Data as of
What the planned projects table contains
Each row is one planned generating unit, not a whole plant. The source for projects, EIA Form EIA-860M, reports at generator level, so a large solar farm or battery site can appear as several rows. The table spans 24 technologies, 51 states and 47 grid operators and balancing authorities, and 7 rows name no grid.
Of the rows, 5,726 (1,255.5 GW) come from the interconnection queues of ERCOT, PJM, MISO, CAISO, SPP, NYISO and ISO-NE, and 2,331 (291.9 GW) come from the planned generator list in EIA-860M. Capacity is stated for 98.6% of rows, and every capacity total on this page adds up only the rows that state one.
Timing is less certain. 95.6% of rows carry an expected in-service year, 1,081 units totaling 162.3 GW show an expected year before 2026 yet are still listed as planned, and 353 have no year at all. Coordinates exist for 28.9% of planned units, against 100% of operating ones, so most planned projects are placed by state, county and grid rather than by coordinates.
Planned capacity by technology
| Technology | Units | Capacity | Share of capacity |
|---|---|---|---|
| Solar | 3,475 | 568.6 GW | 36.7% |
| Battery Storage | 2,444 | 435.8 GW | 28.2% |
| Natural Gas | 870 | 273.2 GW | 17.7% |
| Wind | 613 | 158.1 GW | 10.2% |
| Solar + Storage (Hybrid) | 263 | 46.1 GW | 3% |
| Nuclear | 20 | 29.2 GW | 1.9% |
| Transmission | 94 | 12.6 GW | 0.8% |
| 17 other technologies | 278 | 23.8 GW | 1.5% |
Solar and battery storage together hold 64.9% of planned capacity. Hybrid projects that pair a technology with storage are a technology of their own in this table.

Planned capacity by grid operator
| Grid operator | Units | Capacity | Share of capacity |
|---|---|---|---|
| ERCOT | 2,359 | 532.2 GW | 34.4% |
| Midcontinent ISO (MISO) | 1,684 | 301.4 GW | 19.5% |
| PJM Interconnection | 1,492 | 260.3 GW | 16.8% |
| California ISO (CAISO) | 780 | 186.2 GW | 12% |
| Southwest Power Pool (SPP) | 669 | 129.4 GW | 8.4% |
| New York ISO (NYISO) | 376 | 44.4 GW | 2.9% |
| ISO New England | 131 | 16.9 GW | 1.1% |
These seven hold 7,491 of the 8,057 planned units and 95% of planned capacity.
When planned capacity is expected to be in service
| Expected year | Units | Capacity | Share of capacity |
|---|---|---|---|
| 2026 | 1,233 | 151.4 GW | 9.8% |
| 2027 | 1,716 | 271.3 GW | 17.5% |
| 2028 | 1,692 | 352.3 GW | 22.8% |
| 2029 | 1,058 | 249 GW | 16.1% |
| 2030 | 639 | 165.7 GW | 10.7% |
| 2031 | 195 | 66.4 GW | 4.3% |
| 2032 and later | 90 | 50.9 GW | 3.3% |
| Year before 2026, still listed as planned | 1,081 | 162.3 GW | 10.5% |
| No expected year listed | 353 | 78.1 GW | 5% |
The year is the one given by the source for each unit. It is an expectation, not a commitment.

What is a planned power project?
A planned power project is a generating, storage or transmission unit that has been proposed and is listed in a grid operator interconnection queue or in EIA Form EIA-860M as planned, but is not yet in service. In this table each unit is one row.
What approved accounts can do with it
Members filter this table by state, grid, developer, capacity, county and year, switch to a map, and export the filtered result to CSV or Excel. The seven-day trial includes an export of up to 250 rows. Every account is reviewed by hand.
