Getting connected

How to start electricity service in Connecticut

Start with the delivery utility serving your address. If you later select a competitive supplier, the utility generally remains responsible for the meter, local wires, outages and delivery charges.

Identify your utility

Use your service address or a recent bill to confirm Eversource or United Illuminating.

2

Open utility service

Arrange delivery service, verify the start date and provide any required identity or deposit information.

3

Compare supply plans

Compare plan rate, term, fees, cancellation provisions and renewable content.

4

Enroll with a supplier

Use accurate utility account information and retain the confirmation details.

Delivery utilities

The service address determines the local delivery utility. Eversource serves much of Connecticut; United Illuminating serves portions of the southwest, while municipal and cooperative utilities serve selected local areas.

What is the standard service offer?

Customers who do not select a competitive supplier generally receive a default supply option through the utility. The default supply rate is separate from delivery charges and may change according to the utility's published schedule.

Connecticut energy deregulation and customer choice

Connecticut's energy-choice structure separates local utility delivery responsibilities from eligible competitive electricity-supply offers. The utility continues to maintain local infrastructure and respond to outages; the supplier sets the generation plan, term and contract conditions.

Utility company

Delivery and reliability

Maintains poles, wires, meters and local distribution equipment, restores outages and bills delivery charges.

Competitive supplier

Supply plan and contract

Provides the electricity-supply rate, plan term, renewable content and supplier agreement.

Connecticut FAQs

Frequently asked questions

Can I choose my electricity supplier in Connecticut?

Eligible customers may be able to select a competitive supplier for the supply portion of the bill. Availability depends on the utility territory, service address and current market rules.

Will Eversource or United Illuminating still deliver electricity?

Yes. The local utility generally continues delivery, metering, infrastructure maintenance and outage response.

What should I compare besides the advertised rate?

Review the plan term, fixed or variable structure, monthly charges, early-termination provisions, renewable content and usage assumptions.

How do I know which utility serves my address?

Use a recent bill or the exact service address. ZIP-code guidance alone may not definitively identify a utility boundary.

Are the sample prices on this page current live offers?

No. The displayed cards are illustrative, manually maintained examples. Confirm current prices, terms and availability directly with the provider before enrollment.
