1,752 Projects in the ISO-NE Interconnection Queue

New England's grid operator carries 1,752 projects in its interconnection queue, totaling 193.1 GW of requested capacity in our sealed snapshot of June 11, 2026. That count is the headline — and it comes with an unusual data caveat that shapes everything below. ISO-NE's published feed carries no project status at all. We cannot tell from it which of the 1,752 requests are active, which have withdrawn, and which have energized, because the feed simply does not publish that field. Every one of the 1,752 is classified as "unknown" status in our snapshot, which is 100.0% of the queue.

So read 1,752 with care. A queue position is a request to connect to the grid, not a built, approved, or financed project — and in ISO-NE's case we additionally cannot say how many of those requests are even still live. The "unknown" bucket here does not mean the projects are active; it means the feed gives us no status to report. This is a cross-sectional census of one sealed day, not a trend, and not a build forecast.

An interconnection queue is the ordered list of generation and storage projects that have applied to connect to a regional grid and are working through the operator's study process. ISO-NE publishes the list but not where each entry stands.

What the Snapshot Shows

• ISO-NE lists 1,752 projects in its interconnection queue, according to the sealed interconnection-queue snapshot.

• The ISO-NE queue totals 193.1 GW of requested capacity, per the same sealed snapshot.

• All 1,752 ISO-NE projects carry unknown status — 100.0% — because the feed publishes none.

• The median ISO-NE project is just 26 MW, the smallest of any covered queue.

• The largest single request enables a 2,400 MW injection, per the sealed snapshot.

Every one of ISO-NE's 1,752 projects sits in the unknown-status bucket. The feed publishes no status — that is silence, not activity.

Frequently Asked Questions

Because the status gap is the most important thing to understand here, we answer the common questions up front, before the tables.

Q: What does "unknown status" mean for ISO-NE?
A: It means the published feed gives no status field, so all 1,752 projects are classified unknown — 100.0% of the queue. It is not a statement that they are active or withdrawn; the data simply does not say. We report the silence rather than guess.

Q: Does 1,752 projects mean 1,752 plants are coming to New England?
A: No. A queue position is a request to connect, not a built or financed project. With no status published, we cannot even say how many of the 1,752 are still being pursued. The count is developer intent, not a build pipeline.

Q: Why is the ISO-NE median project only 26 MW?
A: At 26 MW, the median is the smallest of any covered ISO, far below ERCOT's 201 MW or MISO's 150 MW. It reflects New England's land constraints and a queue weighted toward smaller solar, storage, and "Other" interconnection requests rather than giant plants.

Q: How is a sealed snapshot different from re-querying ISO-NE today?
A: A sealed snapshot is the feed as it stood on June 11, 2026, content-hashed and stored append-only so it is reproducible and citable. The live feed is a moving target; the snapshot fixes one day for the record.

Q: Why does ISO-NE show 0.0% withdrawn?
A: Because the feed publishes no status, there is no withdrawn signal to count — the 0.0% is the absence of a status field, not evidence that no project withdrew. Treat it as "unreported," the same way the whole queue is unknown.

Q: What is the largest ISO-NE request?
A: It is a non-controllable objective ETU enabling a 2,400 MW injection — a transmission-enabling entry rather than a single generator, which is why its name reads differently from a typical plant.

The ISO-NE Queue at a Glance

The 26 MW median tells a distribution story: ISO-NE's queue is built from many small requests under a few large transmission-scale entries. That is consistent with a dense, land-constrained region where utility-scale siting is harder than in the open Midwest or Texas.

The Fuel Mix Behind the Queue

ISO-NE is the one covered queue where "Other" leads the mix — a reflection both of New England's project types and of how varied vendor labels land in our keyword buckets. The breakdown below is grouped from the operator's own categories.

"Other" leads the ISO-NE queue at a 31.4% share, the only covered ISO where neither solar, storage, nor wind tops the mix. Read qualitatively, a large "Other" bucket signals interconnection requests that do not map cleanly onto a single generation fuel — transmission-enabling entries, mixed facilities, and labels our keyword grouping cannot confidently sort. Solar leads on project count (522) but carries little capacity (12,555 MW), the signature of many small distributed-scale filings. Wind, by contrast, packs 46,469 MW into 246 projects, pointing to large offshore proposals off the New England coast.

Solar shows 522 ISO-NE projects but only 12,555 MW — a high count, low capacity profile typical of small, distributed filings.

Battery storage and natural gas round out the read in instructive ways. Storage carries 41,089 MW across 290 projects, a solid capacity contribution that reflects New England's interest in firming a constrained grid through cold winter peaks. Natural gas shows 132 projects and 24,467 MW — a meaningful conventional presence in a region that has historically leaned on gas for reliability — while nuclear is vestigial at 11 projects and 149 MW.

Taken together, the fuel picture says ISO-NE's queue is unusually diversified: no single fuel dominates, "Other" leads precisely because so many filings resist clean classification, and offshore-scale wind supplies the heaviest single capacity punch per project. For a planner, that diversity plus the missing status field makes ISO-NE the hardest of the covered queues to read for a clear build signal — which is the honest takeaway rather than a defect to paper over.

How ISO-NE Compares

ISO-NE sits in the middle of the covered queues on project count and near the bottom on requested capacity — quieter on megawatts than CAISO, ERCOT, and MISO, and in line with SPP. The comparison uses each ISO's published headline figures.

Across all covered queues the snapshot holds 10,618 projects and 1600.7 GW spanning 5 ISOs and 28 states. ISO-NE's status gap is its defining feature against peers: where MISO publishes a 56.2% withdrawal rate and CAISO 76.8%, ISO-NE publishes none, so its queue cannot be read for attrition at all. Within ISO-NE's footprint, Massachusetts is the top state with 605 projects — broken out in the Massachusetts interconnection queue report.

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. ISO-NE is a no-status feed, so all 1,752 of its projects are unknown.

The grid disclaimer, restated: a queue position is a request to connect, not a built, approved, or financed project. Nothing here is a forecast. For ISO-NE specifically, the unknown bucket means the feed reports no status — do not read it as active capacity.

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; where no status exists, records go to unknown.

3. Seal. The day's normalized records are content-hashed and stored append-only.

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

Put Grid Data to Work

ISO-NE's queue is a useful early-demand signal even without status, as long as readers treat the count as intent rather than pipeline.

Project developers siting a New England request can read the 26 MW median and the 522 small-solar filings to judge how their proposal fits a queue built from many small entries. EPC contractors and equipment suppliers can use the 290 storage and 246 wind requests — especially the 46,469 MW of high-capacity offshore-style wind — to time inventory and crews to the region's project types. Utilities and policy researchers can flag ISO-NE's complete absence of published status as a transparency gap worth tracking against status-publishing peers.

US Tech Automations automates the monitoring layer: it watches the published feed for new entries, routes the relevant ones to the right desk, and drafts first-pass outreach when a project matches a developer's or supplier's criteria — and it flags where status is missing so the gap is visible, not assumed away.
