38.4% of New Hampshire's Queue Is Solar

Solar accounts for 38.4% of New Hampshire's interconnection queue — the largest single fuel type in a 138-project pipeline that totals 11.1 GW of proposed capacity as of June 11, 2026. A queue position is a request to connect, NOT a built, approved, or financed project. New Hampshire routes through ISO-NE, the regional transmission organization for New England, and ISO-NE's data carries a critical caveat that shapes every number in this report: ISO-NE publishes no status field for its interconnection queue entries.

That means all 138 New Hampshire projects — 100.0% of the queue — carry "unknown" status in our sealed snapshot. This is not a data error. It is a feed characteristic. ISO-NE's public queue data does not distinguish between withdrawn, in-queue, and operational projects in the machine-readable format we consume. The 100.0% unknown figure is a transparency disclosure about what ISO-NE's feed does and does not provide, not a statement about the actual state of these projects.

This report covers 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 our sealed daily grid snapshots. This is a census of the published queues, not of every project on every grid in the country.

Frequently Asked Questions

The FAQ-forward variant for this post moves the most reader-relevant questions to the top, because the two structural features of New Hampshire's data — the Solar-heavy fuel mix and the 100.0% unknown status — generate the most immediate questions from anyone who encounters these numbers.

Q: Why does 100.0% of New Hampshire's queue show unknown status?
A: ISO-NE does not publish a status field in its machine-readable queue data. Our methodology groups projects from feeds that publish no status into the "unknown" bucket. This is a characteristic of ISO-NE's data, not a problem with individual New Hampshire projects. To find project-level status, you would need to consult ISO-NE's project-specific pages or formal interconnection study documentation.

Q: What does 38.4% Solar share mean for New Hampshire's queue?
A: Solar leads the fuel mix at 38.4% by project count, with 53 Solar projects accounting for 2,046 MW. Solar leading in New Hampshire is consistent with the broader New England pattern, where rooftop and community solar programs have driven both small- and mid-size utility Solar filings, and where ISO-NE's queue reflects the region's push toward distributed and utility-scale Solar in states with aggressive renewable portfolio standards.

Q: Does the 11.1 GW queued total mean 11.1 GW is coming to New Hampshire's grid?
A: No. Queue totals represent aspirational proposals, many of which will never be built. Withdrawal rates for ISO-NE territory nationally run at meaningful levels — the national average across covered ISOs is 36.5% — but ISO-NE's feed does not let us see New Hampshire-specific withdrawals in this snapshot.

Q: Why is New Hampshire's median project size only 21 MW?
A: The 21 MW median is the smallest among all covered states in this edition. It reflects ISO-NE's New Hampshire footprint containing many smaller-scale projects — distributed Solar, small community wind, and minor storage filings — alongside a handful of large outlier entries. The median captures the typical project size, and New Hampshire's typical project is much smaller than the national median of 150 MW.

Q: Who files interconnection requests in New Hampshire at this scale?
A: Small-scale projects (under 50 MW) in ISO-NE's New Hampshire territory are commonly filed by community solar developers, small wind developers, and independent power producers targeting distributed generation contracts. Larger entries — including the 1,200 MW HVDC/AC Tie - Import only at the top of the capacity range — reflect a different category entirely: major transmission infrastructure proposals rather than generation projects.

Q: Is the large HVDC entry a generation project?
A: The largest entry in New Hampshire's queue is HVDC/AC Tie - Import only at 1,200 MW. This entry describes transmission infrastructure for importing power into ISO-NE's New England region, not generation capacity sited in New Hampshire. Its presence in the queue under a New Hampshire interconnection point inflates the state's total queued capacity relative to what its generation resource base would suggest.

Key Findings

• 138 projects totaling 11.1 GW (11,124 MW) appear in New Hampshire's ISO-NE interconnection queue as of June 11, 2026, according to our sealed snapshot.

• 38.4% of the queue by project count is Solar — 53 projects totaling 2,046 MW.

• The median project size is 21 MW, the smallest in the covered state set and far below the national 150 MW median.

• 100.0% of projects carry unknown status — ISO-NE publishes no status field in its machine-readable queue data; this is a feed artifact, not a reflection of the projects themselves.

• The largest single entry is HVDC/AC Tie - Import only at 1,200 MW, a transmission infrastructure entry rather than a generation project.

• "Other" fuel entries account for 43 projects and 5,542 MW — the highest-capacity fuel bucket, driven by large transmission and non-standard technology filings.

New Hampshire's Queue at a Glance

The 21 MW median is the distinctive signal in New Hampshire's data. A state whose typical interconnection request is 21 MW is not a utility-scale bulk generation market — it is a distributed and community-scale generation market, with a handful of large entries at the top that pull the total capacity figure upward without changing the character of most of the queue.

All 138 New Hampshire projects — 100.0% of the queue — carry unknown status. That is a disclosure about what ISO-NE's feed publishes, not a judgment on the projects: the operator simply does not expose withdrawn, in-queue, or operational labels in its machine-readable data.

The Fuel Mix in Detail

Solar: 53 projects, 2,046 MW

Solar is the plurality fuel type with 53 projects. In New Hampshire's context, Solar interconnection requests span a wide range: rooftop-adjacent projects seeking commercial-scale grid connections, community solar arrays in the 2–20 MW range, and utility-scale ground-mount Solar in the 50–100 MW tier. The 2,046 MW Solar capacity total across 53 projects implies an average project size consistent with mid-scale utility Solar, though the median tells a different story: most entries are small.

Other: 43 projects, 5,542 MW

The "Other" bucket carries 43 projects and 5,542 MW — the highest-capacity total of any fuel type in New Hampshire's queue. This large Other figure reflects ISO-NE's varied technology labels that do not map cleanly to Solar, Wind, Battery Storage, Natural Gas, or Hybrid categories under our keyword bucketing methodology. Large transmission entries like the HVDC import tie fall here. The 5,542 MW capacity figure for Other should be read cautiously: it is not 5,542 MW of a single generation technology, but an aggregation of heterogeneous projects.

Wind: 23 projects, 969 MW

Wind accounts for 23 entries and 969 MW. New Hampshire's White Mountains and ridgeline locations have historically attracted small- to mid-scale wind proposals, though the development environment has grown more constrained over time. The 23 Wind entries represent ongoing developer interest in the state's wind resource despite project complexity.

Natural Gas: 9 projects, 1,590 MW

Natural Gas contributes 9 projects and 1,590 MW. These are likely peaker and combined-cycle proposals seeking dispatchable firm capacity in ISO-NE's New England grid, where summer peaks drive demand for quick-start generation. The 1,590 MW across 9 projects implies larger per-project size than the Solar and Wind entries.

Battery Storage: 7 projects, 964 MW

Battery Storage adds 7 projects and 964 MW. Standalone storage filings in New England have grown as developers seek to pair storage with the region's renewable generation mandate. New Hampshire's 964 MW battery pipeline is meaningful relative to the state's total capacity footprint.

Nuclear: 3 projects, 13 MW

Three Nuclear entries totaling 13 MW appear in New Hampshire's queue. At 13 MW total across 3 projects, these likely represent small modular reactor or research reactor filings rather than conventional large-scale nuclear plants.

How New Hampshire Compares in ISO-NE

New Hampshire sits within ISO-NE's footprint, alongside Massachusetts, Maine, Connecticut, and Rhode Island. The table below draws from the sealed display set for ISO-NE states plus national reference points.

New Hampshire is the smallest-capacity state in the ISO-NE covered set. Massachusetts leads the ISO-NE tier by a wide margin at 605 projects and 81.3 GW. New Hampshire's 138 projects and 11.1 GW sit close to Rhode Island (123 projects, 11.8 GW) in scale — both are small New England states with distributed-generation-heavy queues. Maine at 37.0 GW reflects its much larger land area and offshore wind opportunity.

The ISO-NE interconnection queue report covers the full New England footprint, and the US Interconnection Queue Index — June 2026 provides the national cross-ISO view.

Methodology

Source: Public ISO/RTO interconnection-queue listings, via our grid-queue clock (sealed daily, content-hashed).

Honesty statement: All figures are computed directly from our 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.

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.

The grid disclaimer: A queue position is a request to connect, NOT a built, approved, or financed project. Nothing in this report implies that queued capacity will be built or is coming online.

ISO-NE status note: ISO-NE publishes no status field in its machine-readable interconnection queue data. All 138 New Hampshire projects therefore show as "unknown" status in this snapshot. This is a feed artifact, not a deficiency of the projects themselves.

Fuel bucketing: Vendor fuel and technology labels differ by ISO and are grouped into Solar, Battery Storage, Wind, Natural Gas, Hybrid and Other by keyword.

Status bucketing: 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.

How the clock works:

1. Collect. The research desk pulls each ISO's machine-readable queue listing daily.

2. Normalize. Records are parsed, fuel and status labels are bucketed by keyword rules, and state attribution is assigned by ISO-reported point of interconnection.

3. Seal. Each snapshot is content-hashed (SHA) into an append-only ledger. This snapshot carries hash prefix 4938600b6a99772e, sealed June 11, 2026.

Automating New England Queue Monitoring

New Hampshire's 138-project queue within ISO-NE is small enough that a dedicated analyst can track it manually — but the ISO-NE footprint as a whole (Massachusetts, Maine, Connecticut, New Hampshire, Rhode Island, and Vermont) runs to thousands of entries. Teams that track the full New England interconnection pipeline face the same problem as any other ISO territory: queue files update frequently, formats shift, and status information is sparse.

US Tech Automations builds automation workflows for exactly this use case. ISO-NE's machine-readable queue files are ingested on a schedule, normalized against our fuel and technology bucketing schema, and diffed against prior snapshots to surface new filings and changes. Alerts route to developers, suppliers, policy teams, or sales organizations based on the triggers that matter to each team.

For teams focused on the Solar pipeline that leads New Hampshire's queue, the same automation layer applies to the Solar interconnection queue report at the national level.
