Most Recent Green Mountain Energy Reviews  


Seamless transition to new energy supplier
When our old supplemental provider substantially increased rates (our primary provider is the outstanding community solar organization Neighborhood Sun), we shopped for renewable energy providers and found Green Mountain. Very pleased with ease of shopping on BGE site and transition to Green Mountain. ERG from Owings Mills MD

switch from verde to green mountain, major price reduction , from Butler PA

Control your monthly bill!
I find GME a pleasure to do business with. My rates are reasonable. *** I love that I get a weekly summary of my usage, it gives me a heads up on what my bill will be, and I always take the opportunity to adjust the amount of energy I consume. I always try to beat the prior weeks consumption. #NEVER ANY SURPRISES!!! Laura, Texas from Temple TX

Switch to Green Energy

Switched to Green energy to get a favorable rate and it is now in place. My only complaint is it took approx 2-3 months for the change to take place. Not sure whose fault this is but when I've switched before the tranistion happened faster.

Dishonest Company

Green Mountain Energy is a dishonest and misleading company. I switched to another energy provider just after 2 months and paid the cancellation fee just to be rid of them!

Blatant Thievery

Do not be fooled by this company. When they u expectedly and viciously raised and doubled their monthly payments we were outraged. Because no matter what we still have to pay the exorbitant rate which Im wondering is legally allowed. There has got to be some criminal element involved. If you are receiving their plan, run away as quickly as possible. If you are considering this company here is your warning. Dont do it!
