Connecticut Interconnection Queue: 323 Projects

The Connecticut interconnection queue holds 323 projects, totaling 38.9 GW of requested capacity in our sealed snapshot of June 11, 2026. The defining feature of this slice is not its size but what its operator declines to publish: status is unknown for 100.0% of those 323 requests.

Before any of that capacity reads as advancing, the standing caveat applies — a queue position is a request to connect to the grid, not a built, approved, or financed plant. These lists are aspirational, and a large share of the requests on them never reach steel in the ground. This report is a cross-sectional census of one snapshot day; it counts what was published, not what will be built.

The Fuel Mix Is Led by "Other"

Connecticut breaks the solar-dominant pattern that runs through most of this batch. Its top bucket is not solar but "Other," at 45.8% of the queue — a sign that the state's filings skew toward transmission, interconnection infrastructure, and technologies that ISO-NE's feed groups outside the standard generation labels. The breakdown below comes straight from the snapshot's keyword-grouped categories.

The "Other" bucket leads at 148 projects and 12,294 MW, well ahead of any single generation type. Read qualitatively, an "Other"-led queue tells you Connecticut's interconnection activity is less about a wave of one technology and more about a mix of infrastructure and assorted filings.

Battery storage and solar tie on count at 61 projects each, but storage carries far more capacity (8,296 MW versus 1,710 MW), the denser profile of grid-scale batteries. Natural gas shows 37 projects at 8,747 MW, and wind concentrates 7,764 MW into just 11 filings — the high capacity-per-project profile typical of large offshore or regional wind. Nuclear is a small tail at 5 projects and 136 MW.

Connecticut is one of the few queues in this snapshot not led by solar — its 45.8% "Other" share reflects a queue heavy on transmission and infrastructure filings rather than a single generation technology.

What the Snapshot Shows

• Connecticut lists 323 projects in its interconnection queue, totaling 38.9 GW of requested capacity, per the sealed snapshot.

• "Other" is the top bucket at 45.8% — 148 of the 323 requests.

• Status is unknown for 323 projects — 100.0% — because the operating feed publishes no status field.

• The snapshot lists 0.0% withdrawn, which is a feed artifact, not a claim that nobody left.

• The largest single request is Non-controllable objective ETU to enable 2400 MW injection at 2,400 MW, per the sealed snapshot.

The 0.0% Withdrawn Figure Is a Feed Artifact

This is the figure most likely to mislead, so it gets its own read. Connecticut shows 0.0% of its projects withdrawn and 100.0% with an unknown status. That 0.0% does not mean no project ever left this queue. It is a feed artifact: ISO-NE, the operator covering Connecticut, publishes its queue without a machine-readable status field, so every project falls into the "unknown" bucket and the withdrawn count is zero by absence of data, not by absence of withdrawals.

The honest posture is to refuse to imply these 323 projects are all active. We do not know their disposition from the published feed. Where MISO states elsewhere in this snapshot expose withdrawal rates where most requests are already gone, Connecticut exposes nothing — and that silence is the finding. Reading 38.9 GW as live, advancing capacity is reading past the data.

Status is unknown for all 323 Connecticut requests — 100.0% — so none of the 38.9 GW can be called active or inactive from the published feed.

This matters most for anyone tempted to rank states by "live" pipeline. A MISO state publishes its attrition, so its active count is legible; Connecticut publishes none, so its 323 projects sit in a single undifferentiated bucket. The right comparison is not "Connecticut has more active capacity" but "Connecticut's feed cannot answer the activity question at all." Treat the 38.9 GW as requested intent under a reporting gap, and treat the gap itself as the headline data-quality fact about this queue.

Connecticut at a Glance

The table pulls the state's headline figures directly from the sealed snapshot. Capacity appears in both megawatts and gigawatts as published; status reflects the feed's limits.

The 50 MW median, against a 2,400 MW top request, says the queue is built from many smaller filings plus a thin tail of very large infrastructure items — the top request is a 2,400 MW injection-enabling element, not a single generator. One structural note: a state's queue can span more than one operator, but Connecticut's requests sit with ISO-NE, the dominant operator across its footprint.

How Connecticut Compares

Set against its parent operator and the national total, Connecticut is a modest slice. The table reads qualitatively.

Connecticut's 38.9 GW is a fraction of ISO-NE's 193.1 GW and a small share of the national 1600.7 GW. Notably, Connecticut's "Other" share (45.8%) runs even hotter than ISO-NE's own (31.4%), and it diverges from the national picture, where solar leads at 39.0%.

The divergence is the analytically interesting part. Nationally, solar is the top bucket at 39.0% and the queue reads as a renewable-generation pipeline. Connecticut inverts that: solar is only 61 projects at 1,710 MW, while the "Other" bucket dominates at 148 projects and 12,294 MW. The 45.8% "Other" share and the 100.0% unknown status make Connecticut a queue best understood as transmission and interconnection work under a reporting gap, not generation advancing toward construction. For the operator-level view that contains Connecticut, see the ISO-NE interconnection queue report; for a technology lens, the battery storage interconnection queue report.

A caution on cross-state status reads: withdrawal percentages are not comparable across operators, because some feeds — ISO-NE's among them — publish no status at all. Connecticut's 0.0% withdrawn is exactly that case: a feed artifact, not a clean queue.

Methodology and the Grid Disclaimer

This report draws on public ISO/RTO interconnection-queue listings, via the grid-queue clock (sealed daily, content-hashed). The scope: generation and storage projects sitting in the interconnection queues of the U.S. grid operators (ISOs and RTOs) that publish a machine-readable queue, as captured by US Tech Automations' sealed daily grid snapshots. This is a census of the published queues, not of every project on every grid in the country.

All figures are computed directly from US Tech Automations' sealed daily grid-queue snapshots; nothing is estimated, modeled, or extrapolated. Fuel and status labels are grouped from each ISO's own categories, and the grouping rules appear in the display set. Vendor fuel and technology labels differ by ISO and are grouped into Solar, Battery Storage, Wind, Natural Gas, Hybrid and Other by keyword. Each ISO publishes its own status taxonomy; statuses are grouped into withdrawn, operational, still-in-queue, and unknown for feeds that publish no status. Some ISOs drop withdrawn projects from their feed entirely.

The grid disclaimer, restated: a queue position is a request to connect, not a built, approved, or financed project. Nothing here is a forecast of capacity that will come online. Connecticut's 100.0% unknown status is its own form of evidence — when a feed cannot tell you what is still active, reading queued capacity as future supply is unsupported.

How we build the snapshot:

1. Collect. We pull each covered ISO's published interconnection-queue feed on its own schedule.

2. Normalize. Differing vendor fuel and status labels are mapped onto common buckets.

3. Seal. The day's normalized records are content-hashed and stored append-only, so the snapshot is reproducible.

4. Aggregate. We compute counts, capacity totals, medians, and status splits across the sealed records for the snapshot date.

Frequently Asked Questions

Q: How many projects are in the Connecticut interconnection queue?
A: 323 projects, totaling 38.9 GW of requested capacity, per the sealed snapshot of June 11, 2026.

Q: What is the top technology in Connecticut's queue?
A: "Other" leads at 45.8% — 148 of the 323 requests — reflecting transmission and infrastructure filings rather than a single generation type. Battery storage and solar tie on count at 61 projects each.

Q: Does 0.0% withdrawn mean no Connecticut projects dropped out?
A: No. It is a feed artifact. ISO-NE publishes no status field, so all 323 projects are logged as unknown — 100.0% — and the withdrawn count is zero by absence of data, not by absence of withdrawals.

Q: Are all 323 Connecticut projects still active?
A: We cannot say from the published feed. With 100.0% of projects carrying an unknown status, the data does not support calling them active or inactive.

Q: What is the largest item in Connecticut's queue?
A: Non-controllable objective ETU to enable 2400 MW injection, at 2,400 MW — an injection-enabling infrastructure element rather than a single power plant.

Put Grid Data to Work

A sealed, daily queue snapshot is an early-demand signal, and each audience reads Connecticut's 323 projects differently — with the status caveat front of mind.

Project developers siting the next request can read the "Other"-led mix and 50 MW median to gauge where Connecticut's queue is crowded. EPC contractors and equipment suppliers can treat the 61 battery-storage and 61 solar requests as a forward order-book signal, while discounting status because the feed publishes none. Utilities and policy researchers can flag the 100.0% unknown status as a data-quality gap worth closing before any of the 38.9 GW is read as advancing.

US Tech Automations builds the automation layer on top of that signal: watching the published feeds for changes, flagging status gaps like Connecticut's, and drafting the first-pass outreach when a relevant project appears or moves.
