What Customers Are Saying About Constellation

Trustpilot



How Energy Choice Works in Connecticut

In Connecticut, utility companies used to be the only option for energy users — the utility company controlled delivery, pricing and maintenance. Today, you can choose the best Connecticut electricity supplier for you, meaning it's easy to compare electric plans near you and select the best rate and plan for your needs.

What does energy choice mean?

Connecticut electric suppliers compete for your business, which can result in reduced energy costs, better customer service, more innovative energy solutions, and energy plans that fit your budget. For example, Constellation offers electricity rates and plans to Connecticut residents with:

  • no sign-up fees
  • exceptional customer service
  • a variety of fixed-rate energy plans

Learn more about energy choice.


Understanding Connecticut Energy Suppliers vs. Utility Companies

Utility companies deliver electricity to your home. This means your Connecticut utility company — which many customers refer to as light and power companies — owns the power lines which deliver energy to you to serve your home.

As a supplier of electricity in CT, we aren't the utility company that delivers electricity to your home, but the provider that sets your rate and contract term. Rather, we provide you with customized energy plans, competitive Connecticut electric rates and exceptional customer service!


Additional Information

To pay your energy bill online, select your local Connecticut utility company below:

  • Eversource: Pay your bill
  • United Illuminating: Pay your bill

If you are experiencing a power outage, call your Connecticut utility company:

  • Eversource: 800-286-2000
  • United Illuminating: 800-722-5584

Sign up to receive power outage alerts from your utility company in Connecticut:

  • Eversource
  • United Illuminating

Supply, demand and regional factors all contribute to electric rates in Connecticut. Without a fixed-rate electricity plan, Connecticut residents with a variable month-to-month plan are susceptible to fluctuating electric rates.
