About Constellation Energy

Constellation Energy, found online at, is a company that describes itself as a leading competitive supplier of power, natural gas, renewable energy, and energy management products in specific areas around the US.

How Does It Work?

Constellation Energy provides their customers with the ability to have an alternative option to their local electricity and gas company. To get started with their services, all you have to do is check to see if they provide service in your area, which plan seems like the best fit for your needs and your budget, and then fill out their simple sign up form online.

Constellation will then take care of contacting your current utility on your behalf and setting up your new service. Your current utility company will still handle all of your equipment, power outages, and emergency services.

Cost/Price Plans

Costs of your monthly plans will rely on a wide variety of factors, including the area where you live, your estimated monthly usage, and whether you will be a residential or business customer. 

Refund Policy

There is no general Refund Policy available with utility companies. There are Cancellation Policies in place during the early stages of membership, though cancellation charges will apply. Like always, if a customer feels as though there has been an unfair charge made on their bill, they can always bring individual issues up for review.

Customer Service Contact Info

The best way for prospective customers to reach Constellation Energy to discuss questions, concerns, or complaints is by phone, at 866-237-7693, or by submitting them directly to their website. Current customers who wish to speak to Customer Service can use their website to find the phone number for the appropriate department to handle their specific issue. 


Generally speaking, Constellation Energy seems to have positive reviews from independent reviewers who like the alternative and renewable energy options they offer their customers, as well as the fact that they are backed by Exelon, a large scale energy company which has been in business for many years.

Competitors and Alternatives?

Energy providers are available everywhere, though not all the same providers are available to everyone. Customers who are looking for an energy company should start by looking at what is available in your local area.
