Data center activity in Connecticut
Connecticut's environment is driven by at least 12 enacted moratoriums, with only one proposal rejected. Zoning has been favorable when projects get there, with at least three approvals and no reported denials, but at least three projects have been blocked by opposition. Regulatory signals are balanced, with one restriction adopted and one rejected. With at least 20 companies active and modest overall coverage, the state has improved over the past quarter and looks more workable than neighboring Massachusetts.
