New Customer from Waterford, NY on August 2nd, 2021
Happy 4 year customer
I've been a customer with Constellation for 4 years and have generally had a positive experience with them as my electricity provider in NY state. While I am cancelling my plan with them this is because they have discontinued their green/renewable energy plan for NY residents. Generally the fixed rates were very reasonable for the wind plan (8 - 10c/kWH) and I did not run into any billing or account issues and would recommend them to other NY residents who aren't looking for a green electricity supplier.

Constellation Energy Group Honest Review
I've been with constellation for a few years. I noticed the rate was always lower than my utility's. My bill doesn't change much either unless I'm using more electric than usual.

Horrible service
I tried switching to constellation and they don't seem to want to do business. They never responded to my calls or emails. I tried at least 3 times.

M & J System Tech from Washingtonville, NY on December 21st, 2020
It's a toss up between pretty bad and positively awful
Three months and three customer service calls to get the billing right. Cannot tell me whether I will get a check or credit on Con-Ed account for their overfilling

JLC from White Plains, NY on December 26th, 2019
Terrible follow through on promises
We had adjustments needed for two business accounts. It took 4 months and many calls to get it done, despite repeated promises to have it done immediately. As well, their online "energy manager" is never current with what the billing department has received, so you can't confirm account status effectively. I do not recommend using them.
