Wonderful company
I have had Green Mountain for years no complaints from me. Great service. Robin Smith from Fort Worth TX

As promised, the rate on my bill only increased slightly. I feel better paying my bill each month knowing it is going towards cleaner sources than before. Five Stars from Syracuse NY

Happy til the end

The price we received with our initial contract was outstanding. No issues during the life of the contract. However, a letter comes and tells us of a 40% increase in price. Therefore, we switched to another provider. And as a parting gift they hit us with a $200 contract cancellation fee.

DONT USE GREEM MOUNTAIN

They may offer competitive prices and plans at first but they always find ways to charge up your bill during your time as a customer. I lived in a one bedroom apt and it cost more using Green Energy to cool and power electronics there than it does in my 4 bedroom two story house. They also have poor customer service and do not process closure claims properly. I closed my account in may and I'm still being billed because they waited a month to close it. This is the SECOND time they have done this to me. 10/10 WOULD NOT RECCOMEND this company, go for TriEagle!! They are great.
