The record, newest first

  1. Scheduled: a P&Z public hearing on a citizen-filed zoning amendment that would define and regulate data centers. (WFSB (Channel 3), Oct. 23, 2026)

  2. The Hartford Courant described the plan: a first phase of about 40 MW of IT power, growing to 300+ MW and 1.2 million sq ft on about 159 acres, with site plan approval to be sought in early 2027. (Hartford Courant (via GovTech/TNS), Oct. 16, 2026)

  3. The Planning and Zoning Commission voted 5-2 against a one-year data center moratorium. (Hartford Courant (via GovTech/TNS), Oct. 16, 2026; CT Mirror, Oct. 25, 2026)

  4. In an email to the town, the developer wrote that it had been working with Cromwell representatives since October 2025; the town manager told WFSB talks went back only several weeks. (WFSB (Channel 3), Oct. 23, 2026)

  5. The town confirmed that the site's business-park zoning permits a data center by right, according to town documents reported by WFSB. (WFSB (Channel 3), Oct. 23, 2026)

Conflicts and open questions

  • CT Mirror gives about 550,000 sq ft and 150+ acres; the Courant gives 1.2M sq ft and about 159-160 acres. The figures conflict.
  • The developer has said it would dedicate more than 25 acres to the town for parkland, athletic fields, a senior center and open space (WFSB).
  • An online petition against the project had more than 1,500 signatures, per CT Mirror. The resident who filed the zoning amendment is not named here.
