Detailed entries
Groton
- Type: Town
- Status: ⚪ Replaced
- Date enacted: 2022-06-14 (Groton PZC adoption, 5-0 vote); effective 2022-07-15, per the adopted motion text in the June 14, 2022 PZC meeting minutes: "This text amendment shall become effective July 15, 2022."
- Normalized date:
2022-06-14(exact) - Duration: One year
- Current end date:
— - Sectors: data center
- Moratorium ID:
ct-groton-2022 - Legal basis: Planning and Zoning Commission application REGA22-01, Data Center Moratorium Text Amendment, town-wide
- What prompted it: Local proposals for large data centers, uncertainty about how data centers differed from telecommunications facilities, and resident concerns about noise, stormwater, generator use, energy use, and environmental impacts
- Affected projects: Data center applications; public reporting states the pause applied to developments larger than 5,000 square feet and followed proposals for two 250,000-square-foot facilities near Interstate 95
- Detailed status: Replaced
- Outcome: Permanent regulations adopted in 2023 limit principal data centers to 12,500 square feet and impose siting and operating limits; public reporting describes this as blocking hyperscale projects
Morris
- Type: Town
- Status: 🟢 Active
- Date enacted: The identical moratorium text (prepared by the Town Planner and dated 2026-03-23) was re-filed by the Commission under its 'regulations' folder -- rather than the earlier 'generals'/draft-agenda-attachment folder it occupied as of the April 15, 2026 meeting -- under the title 'Public Hearing Two Year Moratorium on Battery Storage Facilities and Data Centers,' with a document date of 2026-05-20. Secondary reporting describes a public hearing held on a Tuesday and Commission approval the same week, consistent with adoption around 2026-05-19/20. Neither the exact adoption-vote date nor the Connecticut-statute-required newspaper publication date (which triggers legal effectiveness) was found in any source I could access.
- Normalized date:
2026-05(month_only) - Duration: 12 months from effective date of adoption
- Current end date:
— - Sectors: battery storage, data center
- Moratorium ID:
ct-morris-2026 - Legal basis: Town of Morris Planning and Zoning Commission, Zoning Moratorium on Battery Energy Storage Systems and Data Centers
- What prompted it: Need to evaluate land use, environmental, infrastructure, fire safety, emergency response, groundwater, traffic, noise, visual, electrical infrastructure, and water-use impacts
- Affected projects: Applications for establishment, construction, installation, or expansion of battery energy storage systems or data centers; no named project identified
- Detailed status: Adopted. The Commission's own document repository shows the moratorium text moved from a 'generals' (draft/agenda-attachment) filing on 2026-04-15 to a 'regulations' filing dated 2026-05-20, and secondary press reports the Commission approved the moratorium following a public hearing in mid-May 2026. The operative text (Section 6) fixes a 12-month term running from the effective date of adoption, notwithstanding press descriptions of it as a 'two-year moratorium' (which do not match the adopted text I read).
- Outcome: Pending; moratorium directs the commission to prepare zoning amendments as appropriate
New Haven
- Type: City
- Status: 🟡 Pending
- Date enacted: Not yet adopted as of 2026-07-06; proposed by Board of Alders Majority Leader Richard Furlow as a communication on the Monday Board of Alders agenda, to proceed next to an aldermanic committee for a public hearing before returning to the full board for a final vote.
- Normalized date:
—(unverified) - Duration: Proposed 12 months

- Moratorium ID:
ct-new-haven-undated - Legal basis: Proposed Board of Alders resolution/ordinance (introduced as a communication; not yet referred to committee as of 2026-07-06)
- What prompted it: Proactive/regulatory-gap: the city has no zoning framework for data centers and wants to develop one before any project is proposed, drawing on approaches used by Groton, Morris, and West Haven, Connecticut.
- Affected projects: None. New Haven's Deputy Director of Zoning stated there are no current proposals or plans by any entity to build a data center in New Haven.
- Detailed status: Pending; introduced 2026-07-06, awaiting aldermanic committee referral and public hearing before a final Board of Alders vote.
- Outcome: Proposed 12-month moratorium to allow the city's economic development department to convene a working group evaluating opportunities and impacts before any zoning framework is adopted.
