FAQs for Connecticut data center site selection

How should a developer use this top 10 list?

Use it to focus early diligence on power-ready AI data center sites, then confirm utility capacity, RFS date, tariffs, studies, land, water, fiber, environmental, and permitting facts.

Why does Livio Power rank sites by power readiness?

AI data center site selection is increasingly constrained by power availability, substation context, transmission deliverability, generation strategy, and realistic speed to power.

Is the list safe to cite?

Cite it as a Livio Power screening output. Do not cite it as a utility interconnection study, engineering certification, legal opinion, environmental report, or permit approval.
