The change over to better rate was very easy. Thanks.

Price is good

Great communication and customer service

I am a Constellation customer for the last 8 years . I have renewed contracts multiple times with them . In 2024 a customer rep confiremd 13.9c all inclusive including centrepoint delivery charges. Since i had been with them for 6 years before that i never had any problems. After 2 years i looked at the bill and found the rate excessive. They had charged me 17c a KWH. It was a rude shock to me. I didnt expect anybody handling customer service on bahalf of Constellation to operate this was. I called them immediately and told them that they had something wrong. They did not refund me for the eextra charges for the last 2 years. I used approximately 15000 kwh x .05 cents a KWH =$750. I am putting this review online so people can be aware how publicly listed companies cheat customers with the help of customers service reps. Updated 7/31/26 I called next day just to confirm Constellation had not lied to me yesterday. I called your customer service reps yesterday Mauricio Ext 815 And Frank Phillips ext 898 . They confirmed a change to an 11 month plan which would take effect within 24 hours and today I called just now. They deny that my call has a record and they say they will change the plan from the 17th of August. So customer service reps are lying on a daily basis. I asked the rep today to speak with those customer service reps from yesterday and they said they could not be reached . It is truly appalling to communicate with Constellation. Constant lies. New lies everyday.

Very easy to set up the account and the rate was the best out of all the companies! The rate is lower than UI’s off peak rate. It’s saving me $40 a month.
