For so many years, since I transferred my service to Constellation Energy, I like their energy rate. They have the cheapest rate compared to my previous providers. Their customer care service is very helpful and easy to talk to. They will try their best to solve my concerns or issues.

I have been with constellation for 15 years. I stay with them because they don’t go up all the time like electric companies do. They’re pretty fair on pricing per kilowatt and when you call to talk to someone at constellation, they have not been rude. They have been kind and help with your problem if you have one or question.

I have been with Constellation for sometime now. Customer Service is really good and their rates are very competitive.

A very happy customer! I’ve been with Constellation now for many years. I love that they keep me informed of how many kilowatts I have used on a weekly basis. It gives me an idea of how much energy I have used and informed on those days when they are higher. I keep tabs on my account. I appreciate knowing and anticipating what my bill will be each month. By the same manner, I welcome those tips on how to conserve energy and lower my bill.

No problems so far. I once had to call Constellation and got someone on the phone. being able to speak directly to someone is important.
