Connecticut at a glance
The largest footprint in Connecticut belongs to Lumen Technologies, behind 5 tracked facilities. CyrusOne LLC, Digital Realty Trust, Inc., and Prime Data Centers round out the most active operators in the state. Many of these sites are filed under shell or project names rather than the parent's — our operator column resolves them back to the real corporate parent wherever the chain is documented.
Geographically, the buildout clusters: Western Connecticut County leads Connecticut with 2 facilities and a composite risk score of 6/100. Capitol County and Greater Bridgeport County follow. Our county risk score weights project exposure (40%), power demand (30%), water draw (15%), and land footprint (15%); the full breakdown is shown on each county page.
Connecticut is not done growing. 3 facilities are in the pipeline — proposed, permitted, or under construction — which is where residents still have a say at zoning hearings and in rate cases. Each pending project is a decision about land, water, electricity prices, and tax revenue that hasn't been finalized.
We also surface the accountability trail: 1 state bill mentioning data centers and 6 recent news items are tracked for Connecticut below, pulled from LegiScan and GDELT and refreshed automatically. Legislation is linked to the counties and operators it names; news is classified by community sentiment.
2035 Buildout Outlook
Under the model's moderate-growth scenario (5%/yr annual load growth), PNNL's IM3 model sites about 1 standardized 36 MW campus in Connecticut by 2035 — roughly 36 MW of new electricity demand and ~35 M gal/yr of cooling water. Under the higher-growth scenario (15%/yr) that climbs to 3 campuses (108 MW). For scale, we currently track 19 real data centers in Connecticut (1.5 GW of reported power).
- High growth136 MW · ~35 M gal/yr cooling water
- Higher growth3108 MW · ~104 M gal/yr cooling water
The model assigns ~100% of these campuses' cooling to evaporative water cooling in Connecticut (the rest to mechanical/air cooling), a split it derives from local water stress and wet-bulb temperature.
These are modeled candidate sites, not announced or permitted facilities. PNNL's IM3 model places identical 36 MW unit-campuses at feasible locations under each scenario — it shows where demand could concentrate, never a specific parcel. Figures use a market-gravity weight of 50. How the model works.
