Thank You Green Mountain
During the winter storm here in Texas I was so nervous that my bill would go through the roof.
I was one of the lucky ones who did not lose power. I'm a senior and was very very concerned that I would experience price gouging. I did not and I can't tell you how proud I am to be a Green Mountain Energy customer because if it. As we know, other electric companies did try to price gouge.....So sad and so wrong during a time of great devestation....
My complete and sincere gratitude and compliments to Green Mountain Energy for their
honesty and obvious care and concern for their valued customers...
Thanks again and job well done
Green Mountain.
I will continue to recommend your services to family,friends and others...

Very Happy with Green Mountain Energy
I normally never, ever take the time to write reviews but after seeing so many bad ones, I felt compelled to share my experience with Green Mountain Energy. I have been a completely happy customer with them, and their customer service is beyond great. No hidden fees, prices are exactly what we agreed to. I highly recommend this company. Also, during the Texas freeze this year, we NEVER lost power save for the couple hours in the middle of the night due to mandatory rolling blackout. Happy Customer from Spring TX

Love Green Mountain Energy
I've been with them for over 5 yrs. no gimmicks. not the cheapest rate but best bargain overall when you have stability of fixed rate and no unexpected fine prints. Truli from Richardson TX

Big Fan of GME

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.

No more Solar plans from a Green Company??

We put 1.75 MHZ into the grid this month and pulled ~1,100 KW and we got a bill for 90$ - how does that math work? I called Green Mountain to check and see if it was just an error but was informed that the plan we were on no longer exists (they did not contact me) and they ONLY have a month-to-month plan available now AND that is it - meaning the price can/will vary as Green Mountain deems necessary. Adding to this, what happen to the ~600 KW+ our panels put on the grid?? I was told by Green Mountain that the energy amount added to the grid by our panels was less than we burned as reported by Oncor. Sorry - I was born at night, but not last night. I have moved to Rhythm Ops, LLC and recommend all Solar panels owners using Green Mountain consider the same or plan on the month-to-month reality.
