The power behind Connecticut's data centers
EIA-860M lists 185 operating power plants in Connecticut totalling 10,998 MW of nameplate capacity, of which 47 are natural gas plants. That is the supply these 5 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 Connecticut: FAQ
- How many data centers are in Connecticut?
- 5 are on the public record this directory reads: 0 in county or city permit GIS and 5 in OpenStreetMap. Connecticut has no state register of data centres, so that is a lower bound rather than a count.
- Where are the data centers in Connecticut?
- Mostly around Glastonbury, which holds more of these records than anywhere else in the state. The map above plots all 5 and the city table breaks them out.
- Is there a data center near me in Connecticut?
- 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 Connecticut says. A permit records a data center; it does not record the tenant or the workload. Where an AI data center exists in Connecticut it is in this list without being labelled as one, and this page will not guess which.
- Who operates Connecticut data centers?
- CyrusOne 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 Connecticut data centers are under construction or planned?
- No source covering Connecticut 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.
