The power behind New Hampshire's data centers
EIA-860M lists 61 operating power plants in New Hampshire totalling 4,582 MW of nameplate capacity, of which 3 are natural gas plants. That is the supply these 3 facilities draw on. None of these data-centre records states a load, so this page draws no line between the two — it only puts them in one place.
Data centers in New Hampshire: FAQ
- How many data centers are in New Hampshire?
- 3 are on the public record this directory reads: 0 in county or city permit GIS and 3 in OpenStreetMap. New Hampshire has no state register of data centres, so that is a lower bound rather than a count.
- Where are the data centers in New Hampshire?
- Mostly around Portsmouth, which holds more of these records than anywhere else in the state. The map above plots all 3 and the city table breaks them out.
- Is there a data center near me in New Hampshire?
- The city table below groups every facility on record by city, which is the quickest way to find the data center closest to a given town. This site does not read your location.
- Are these AI data centers?
- Unknown, and no public record in New Hampshire says. A permit records a data center; it does not record the tenant or the workload. Where an AI data center exists in New Hampshire it is in this list without being labelled as one, and this page will not guess which.
- Who operates New Hampshire data centers?
- FirstLight appears against more of these records than any other operator. Where a source names no operator the row says so rather than guessing one.
- How many New Hampshire data centers are under construction or planned?
- No source covering New Hampshire publishes a build status, so this page shows none. Status is only available where a county publishes its permit layer.
- How current is this, and what is left out?
- OpenStreetMap extract 2026-09-17; county permit capture 2026-09-12. Power draw, tenant, commissioned megawatts and lease terms are not in any of these public records and are not shown anywhere on this site.
