Price is a little higher than I want, but the length of the service was what made me switch back to Constellation.

Hi Greg, We appreciate your feedback about our rates. We do our best to make our sign-up process an effortless experience and will continue to make improvements based on feedback like yours. We do offer a calculator at the top of the plan selection page where you can put in your kWh usage and it will calculate the cost of each rate in the plan's box under the kWh rate. We are looking at other ways to help prospective customers understand each plan and the rates. Thank you for your review, and if you ever need help with anything, please feel free to reach out to us through our Facebook page at: https://www.facebook.com/ConstellationEnergy/. Additional contact options can be found at: https://www.constellation.com/about-us/contact-us.html. Thank you.

Coming from out of state, everything was straight forward and explained in site. No jumping around to navigate. Put in order and everything was accomplished in no time at all. When we moved in power was on.

Constellation Was More Expensive
I received a letter saying that I was being signed up for Constellation energy aggregation without my knowledge. After reading the letter which seemed purposefully confusing with the way they presented their prices and wording, I could see that the Constellation price was higher than what I was currently paying for residential electricity. There was a code to go online and complete an Opt-Out form or an option to mail it in. After finding the correct web page I completed the Opt-Out form online. I do worry about people who may have difficulty reading or comprehending this due to age or illness being charged more for their energy needs because they can’t understand the paperwork or the Opt-Out process.

Hello, We appreciate your feedback and apologize for your experience. Your town or city should have sent you a communication letting you know that they elected to participate in the gov agg program and what next steps you needed to take to participate or not. If you did not receive this communication, we suggest reaching out to your local leaders to let them know. Thank you.

No information after signing up
Once i signed up, I never received a welcome package or account number. This happened for 4 different homes that I signed up for service. I had to use the online chat feature to get the account numbers. Also, had a terrible experience with their "identity verification" process.

Hi Margaret - We are very sorry to hear about your experience. After speaking with our Customer Care team, they did confirm that their records show that a welcome package was mailed to you by postal mail and a confirmation email was sent to you right after you signed up. We have sent you an email associated with this review. If you could please respond to that, we will have our customer care team look into this further to make sure we have the correct information on file and share your feedback with them. Thank you.
