Finally Fair Rates!
I would just like to express exactly why I am so far absolutely satisfied with the bill as well as the terms of service that Constellation provides for me. Before, my monthly bill came to almost $200.00!! Now it has been $60.00 a month!!

Happy with Constellation so far
Left champion after 3 years when my contract expired and they jumped my price from about 7 or 8 kwh to 15 and my bill went up $200 for that month. They would not adjust at all so I dropped them. Constellation took over in November and the weather cooled off but the bill has sure gone down.
