Notes on the record

Existing enterprise data center in a 153,462 sq ft building built in 1982. In June 2022 Windsor's Town Council unanimously endorsed a host municipality agreement for a planned $386M renovation ($100M software, $286M taxable personal property over five years), with no local tax abatement. Per a 2026 report on a state audit, Cigna is the only company to have received Connecticut Qualified Data Center Incentive Program benefits: $863 million in qualified investments, over $17 million in credits, and 5 jobs created. investmentUsd records the $863M qualified-investment figure, which counts equipment and software purchases and is not the construction cost. No MW figure is published.
