6,729 Projects in 4 Grid Queues: 47.8% Are Withdrawn
Four grid operators list 6,729 projects totalling 1231.9 GW in a single sealed snapshot, and 47.8% of those listings are marked withdrawn. That share needs two qualifiers: 33.8% of listings sit in an Other group that names no fuel, and 26.0% carry no status.
Scope: generation and storage projects listed by CAISO, ISO-NE, NYISO and SPP in the current allowed source universe, as captured by US Tech Automations’ sealed grid snapshots. ERCOT and MISO are withheld from collection, and PJM, the largest US queue, is not in the covered set, so this is a census of the named covered queues, not of every project on every grid in the country. A queue position is a request to connect, not a built, approved, or financed project.
47.8% of the 6,729 listed projects are marked withdrawn.

The Queue at a Glance
| Measure | Sealed value |
|---|---|
| Listings (projects) | 6,729 |
| Total capacity | 1231.9 GW (1,231,905 MW) |
| Median project size | 100 MW |
| Withdrawn | 3,218 (47.8%) |
| Still in queue | 1,427 (21.2%) |
| Operational (explicitly in service or commercial operation) | 337 (—) |
| Unknown status | 1,747 (26.0%) |
| Withdrawn share of known-status listings | 64.6% |
| Largest named entry | ATLAS COMPLEX, 3,200 MW |
| Operators covered / withheld | 4 / 2 (ERCOT, MISO) |
| States in the set | 29 |
The withdrawn bucket is the largest status group, with 3,218 listings against 1,427 still in queue. Operational listings are few at 337, and that label is the strictest in the methodology, so it should not be read as a measure of how many projects are working.
The unknown bucket holds 1,747 listings, the same count as ISO-NE's listings. That match fits ISO-NE publishing no status, but the sealed set does not break the figure out by operator, so treat it as a likely explanation rather than a confirmed one.
Where the Capacity Sits
| Fuel group | Listings | Capacity |
|---|---|---|
| Other | 2,272 | 413,908 MW |
| Solar | 1,769 | 218,654 MW |
| Battery Storage | 1,185 | 243,084 MW |
| Wind | 999 | 211,493 MW |
| Natural Gas | 366 | 115,484 MW |
| Hybrid | 95 | 20,835 MW |
| Hydro | 19 | 5,022 MW |
| Nuclear | 15 | 311 MW |
| Coal | 9 | 3,115 MW |
Battery Storage is the distinctive line in this table. It carries 243,084 MW, more than Solar's 218,654 MW, from 1,185 listings against Solar's 1,769. Storage requests are fewer but larger on average, which suggests developers are asking for large sites.
Other is the largest group by both count and capacity, and it needs the most care. The grouping is keyword-based, and several of the largest named entries are transmission lines and ties, which appear to fall through to Other. Read it as a residual, not as a technology.
The Other group holds 2,272 listings and 33.8% of the set. It is a keyword residual, not a technology.
Hydro, Nuclear and Coal labels also appear in the sealed set. They are reported as published, and they sit outside the grouping rule described in the methodology.
Battery Storage holds 243,084 MW across 1,185 listings.
Four Operators, Four Different Queues
| Operator | Listings | Capacity | Median | Withdrawn | Top fuel group |
|---|---|---|---|---|---|
| CAISO | 2,278 | 492.2 GW | 128 MW | 77.5% | Solar (46.1%) |
| ISO-NE | 1,747 | 193.1 GW | 26 MW | 0.0% | Other (31.3%) |
| NYISO | 1,687 | 355.4 GW | 100 MW | 86.1% | Other (97.6%) |
| SPP | 1,017 | 191.2 GW | 158 MW | 0.0% | Wind (34.3%) |
CAISO is busier than the other three operators on both listings and capacity. Its top fuel group is Solar, and its largest named entry, ATLAS COMPLEX, is also the national largest at 3,200 MW.
ISO-NE shows a median of 26 MW, well under the other three, and a 0.0% withdrawn share. Its top group is Other at 31.3%, and its largest named entry is a 2400 MW elective transmission upgrade, not a generator.
NYISO's withdrawn share of 86.1% is above CAISO's 77.5%. Almost all of its listings, 97.6%, sit in Other, so its withdrawn figure is the more useful part of that row. Its largest named entry is Blue Sky Interconnect 2. For one-operator detail, see our NYISO interconnection queue report.
SPP has the highest median in the table at 158 MW. Its top fuel group is Wind at 34.3%. The sealed set places all 95 hybrid listings in SPP.
A 0.0% withdrawn figure is what the feed publishes. It is not proof that no project in that queue withdrew.
NYISO shows 86.1% withdrawn across 1,687 listings.
The State Picture
The set spans 29 states. The rows below are the states that appear in the sealed state leaderboard, and each row is attributed to the operator that covers most of its listings.
| State | Listings | Capacity | Top fuel group | Covering operator |
|---|---|---|---|---|
| California | 2,076 | 416.8 GW | Solar | CAISO |
| New York | 1,660 | 350.1 GW | Other | NYISO |
| Massachusetts | 605 | 81.3 GW | Solar | ISO-NE |
| Maine | 407 | 37.0 GW | Solar | ISO-NE |
| Connecticut | 322 | 39.0 GW | Other | ISO-NE |
| Oklahoma | 313 | 58.4 GW | Wind | SPP |
| Kansas | 183 | 38.0 GW | Wind | SPP |
| New Hampshire | 138 | 11.1 GW | Solar | ISO-NE |
| Rhode Island | 123 | 11.8 GW | Solar | ISO-NE |
| Nebraska | 116 | 18.9 GW | Wind | SPP |
| Vermont | 109 | 7.8 GW | Other | ISO-NE |
| Texas | 107 | 22.9 GW | Wind | SPP |
| Nevada | 104 | 27.0 GW | Solar | CAISO |
| Colorado | 74 | 13.3 GW | Wind | SPP |
| Arizona | 72 | 33.0 GW | Solar | CAISO |
| Missouri | 66 | 11.5 GW | Battery Storage | SPP |
| New Mexico | 57 | 10.8 GW | Wind | SPP |
Texas appears here only through SPP. ERCOT is withheld, so the Texas row is a partial view of the state's queue, not the whole of it. See our ERCOT interconnection queue report for that queue.
Wind is the top group in every SPP-covered row except Missouri, where Battery Storage leads. That pattern follows the operator's own mix rather than any state-level policy.
Every New England row names a transmission item as its largest entry. Massachusetts's is a 345 kV AC line, and Maine's is an AC line. Connecticut's and Rhode Island's are elective transmission upgrades. New Hampshire's and Vermont's are HVDC ties. Read New England's listing counts with that in mind.
The Arizona and Nevada rows come through CAISO, and ATLAS COMPLEX is the largest named entry for both CAISO and Arizona. One named entry can sit under more than one row, so do not sum state rows into a national total.
Coverage is the four operators in the allowed source universe; PJM, MISO, ERCOT and other operators that publish queues are not included.
Technology Leaderboard
| Technology | Listings | Capacity | Withdrawn share | Operator holding most listings |
|---|---|---|---|---|
| Solar | 1,769 | 218.7 GW | 47.1% | CAISO (1,051) |
| Battery Storage | 1,185 | 243.1 GW | 42.1% | CAISO (689) |
| Wind | 999 | 211.5 GW | 33.1% | CAISO (405) |
| Natural Gas | 366 | 115.5 GW | 33.9% | ISO-NE (132) |
| Hybrid | 95 | 20.8 GW | 0.0% | SPP (95) |
| Other | 2,272 | 413.9 GW | 62.5% | NYISO (1,646) |
Battery Storage's 42.1% withdrawn share sits between Solar's 47.1% and Wind's 33.1%, so storage is not clearly more or less durable in this queue than the other large groups. CAISO holds most of the solar, battery and wind listings, while NYISO holds most of Other.
The Hybrid row shows 0.0% withdrawn because all of its listings sit in SPP, the operator whose feed shows no withdrawals. That is the feed effect described above, not a finding about hybrid projects.
Other holds 33.8% of listings, more than any named fuel.
Key Takeaways
The 47.8% withdrawn figure is a share of all 6,729 listings at one date. It is a census of requests, not a count of outcomes.
The 0.0% readings for ISO-NE and SPP are feed output. The 1,747 unknown listings say nothing reliable about their status.
Battery Storage shows where storage requests cluster, not where storage will be built.
Other is a residual. Check whether a listing is transmission before counting it toward a region's generation.
Methodology
Source: Public ISO/RTO interconnection-queue listings, via the US Tech Automations grid-queue clock (sealed daily, content-hashed).
All figures are computed directly from the named allowed sources in US Tech Automations’ sealed grid-queue snapshots; nothing is estimated, modeled, or extrapolated.
Sources withheld from collection are excluded even when older rows remain in the local archive. ERCOT and MISO are withheld in this edition. Coverage is the four operators in the allowed source universe; PJM, MISO, ERCOT and other operators that publish queues are not included. A coverage change is not treated as a market event.
Vendor fuel and technology labels differ by ISO and are grouped into Solar, Battery Storage, Wind, Natural Gas, Hybrid and Other by keyword. Hydro, Nuclear and Coal labels are reported as published.
Each ISO publishes its own status taxonomy. Statuses are grouped into withdrawn, operational (explicitly in-service or commercial operation), still-in-queue, and unknown for feeds that publish no status. Some ISOs drop withdrawn projects from their feed entirely, so a 0.0% reading is not a claim that none withdrew.
The scope describes generation and storage, but several of the largest named entries are transmission lines, HVDC ties or elective transmission upgrades. This edition reports the sealed figures as they stand, so read the totals and the Other group with that in mind.
A queue position is a request to connect, not a built, approved, or financed project. Interconnection queues are aspirational, and a large share withdraw before construction. Nothing here forecasts capacity coming online.
This is a single sealed day, so every count is a net listing on that date, not an outcome. For single-operator detail, see our CAISO interconnection queue report.
Collect. Pull each covered operator's public queue listing for the sealing day.
Normalize. Map each operator's fuel and status labels to the groups above by keyword.
Bucket. Assign withdrawn, operational, in-queue or unknown status, and leave a listing unknown where the feed publishes no status.
Seal. Aggregate by operator, state and technology, then content-hash the day's snapshot.
Frequently Asked Questions
Q: Does a queued project mean it will be built?
A: No. A queue position is a request to connect. This snapshot lists 6,729 projects, and 47.8% of them are already marked withdrawn. Nothing in the set shows capacity coming online, so read every listing as a request that may not proceed.
Q: Why do 26.0% of listings have no status?
A: Each operator publishes its own status taxonomy. A feed that publishes no status is placed in the unknown group, and 1,747 listings land there in this snapshot. Unknown does not mean active, and it does not mean withdrawn.
Q: How is a sealed snapshot different from a live feed?
A: A live feed changes whenever an operator updates it. A sealed snapshot is one day's listings, normalized and content-hashed, so the figures can be cited later and checked against the same record. This edition is sealed as of October 19, 2026.
Q: Why does the Other group hold so many listings?
A: Other is the residual when a label does not match a fuel keyword. It holds 2,272 listings and 33.8% of the set, and its largest named entries include transmission items. Treat Other as unclassified capacity, not as a technology mix.
Q: Where do battery storage requests cluster in this set?
A: The sealed field places 689 battery listings in CAISO, out of 1,185 storage listings across all covered operators. Battery Storage holds 243,084 MW, more than Solar's 218,654 MW. That describes where requests sit, not where storage will be built.
Put Grid Data to Work
Three roles fit this set. Project developers screening sites can watch the battery and solar rows for their target operator and check the withdrawn share before committing development spend. The weekly question is whether a listing's status has moved. EPC contractors and equipment suppliers can read the Battery Storage line, 243,084 MW across 1,185 listings, as a prospect list, and qualify each listing before they staff a bid. Grid-adjacent teams, including utility planners and energy buyers, can track the unknown share by operator, since 1,747 listings with no status limit how far any planning view can go.
Agentic workflows automate this monitoring by checking feeds on a schedule, alerting when a listing's status label changes, and routing the change to the right account owner.
