Switching Connecticut Energy Suppliers

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

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!
