State-level measures in New Hampshire
Every statewide moratorium, pause, siting restriction, or tax-incentive rollback in New Hampshire we can verify against a primary source. Strongest status first.
| Measure | Status | What it does | Source |
|---|---|---|---|
| Announced budget proposal (2027 session)Proposed statewide multi-year data center moratorium | Proposed 2026-09 | Gov. Kelly Ayotte told the Executive Council on Sept. 2, 2026 that she opposes siting data centers in New Hampshire and intends to include a multi-year statewide moratorium in her next budget proposal, citing electricity prices and water and noise impacts. Because the proposal would travel with the budget, it would not take effect before July 2027 unless the Governor acts sooner by executive order. No bill has been introduced. | |
| LSR 2027-0002 / LSR 2027-0048Proposed 24-month statewide moratorium on data center development (2027 session) | Proposed 2026-09 | On September 2, 2026, New Hampshire House Democrats announced two legislative service requests, LSR 2027-0002 and LSR 2027-0048, sponsored by Rep. Tom Cormen (D-Lebanon), for the 2027 session. The proposals would impose a 24-month statewide moratorium on data center development while the state sets standards, and would require facilities above 30 megawatts to bear the grid costs they create. The requests are drafts for a session that begins in January 2027 and have not been filed as bills. This is separate from Gov. Kelly Ayotte's announced budget proposal. | |
| SB 439Moratorium on AI data centers | Proposed 2026-09 | New Hampshire Senate Republicans, led by Senate President Sharon Carson, announced on September 18, 2026, their intent to pursue legislation for a moratorium on AI data centers; this follows Governor Kelly Ayotte’s public support for such a moratorium and comes after two new data center proposals were announced in the capital region. | |

Wendy Thomas, Requires public utilities to submit annual reports detailing transmission costs | Failed / vetoed 2026-01 | In New Hampshire, HB 1724, Sponsored by Rep. Wendy Thomas, Requires public utilities to submit annual reports detailing transmission costs, wholesale electricity market impacts, and generation capacity adequacy, with specific analysis of data center-related demand. Mandates public hearings and review by the state energy agency. Referred to the House Science, Technology and Energy Committee with a public hearing held February 10, 2026. HB 1724 (utility transparency/cost reporting incl. data-center demand analysis) died due to inactivity. | |
| HB 1265One-year data center construction moratorium | Failed / vetoed 2026-03 | Would bar starting construction of any new data center statewide for one year and create a study committee; the House killed it Mar 11 2026. |

This page is generated from the same primary-sourced dataset as the national U.S. Data Center Moratorium Tracker and is re-checked on the same weekly cycle, whether or not anything changed.

Why New Hampshire is pushing back
The objections repeat from state to state: strain on the electric grid, water drawn for cooling, and the sense that a facility takes local resources without giving much back. SAVRN builds AI factories designed around those three objections: on-site power that does not lean on the public grid, direct-to-chip cooling that does not consume municipal water, and a training institute that puts local people to work inside the building.
