Connecticut City & Town Electricity Guides

Connecticut · City and town electricity guides

Find a local starting point for your business electricity review

Browse 168 Connecticut principal municipalities with documented Eversource/CL&P or United Illuminating service presence. Each location has its own guide. Utility presence does not establish the serving provider or supply eligibility of every address in a municipality.

Prepare your Connecticut business electricity review

Start with the actual service address, utility bill and contract renewal date. Review the information to prepare before continuing to the business inquiry form.

What this directory covers

The principal-town framework follows official Connecticut municipality identities, merging coextensive town/city names. The service evidence includes CL&P’s May 2026 municipality notice and UI’s service-area list. Municipal systems can coexist with investor-owned utility service; use the actual business bill to establish the provider and rate class.

Bozrah is not included in this competitive-supply directory because eligibility has not been established by this audit. That is not a declaration that every Bozrah account is ineligible. Boroughs, villages and Census-designated communities require separate identity and service checks; this directory does not claim coverage of every named settlement.

Browse the nine current planning regions

These groups follow 2025 Census planning-region geography. Historical county areas, where discussed in individual guides, are a separate geographic framework.

Prepare your documents before comparing

Bring a recent utility bill, usage history, demand or interval data where available and the current agreement. Record operating changes and renewal dates. Ask which charges are included, how volume changes are handled and who may authorize enrollment.
