Our Opinion

Green Mountain Energy can be a good choice for customers who want to switch to a renewable electricity plan. We recommend fixed rate plans.

Some customers express frustration with variable rate plans, where prices are unpredictable and may very well exceed rates offered by your local utility. Compare reviews with other suppliers.

We recommend fixed rate electricity plans with Green Mountain Energy.

  • Rates are the same for entire contract
  • Early termination fee up to $150
3, 6, or 12 months
  • 100% solar
  • 100% wind
  • 90% solar, 10% wind
12 month plans may be a good deal
  • Rate subject to change each month
  • No cancellation fee
  • Rate will not exceed prior month by more than 30%
  • Can take up to two months to cancel
None - automatically renews each month
  • 100% wind
Not recommended

Normally we do not recommend contract lengths of 12 month or less for fixed rate electricity plans, because the market price of electricity fluctuates so much in one year that they may not be a good deal. However, if you are able to lock in a competitive rate, the added value of renewable energy may be worth it. Avoid fixed rate contracts of less than 12 months.

We do not recommend variable rate plans because they are subject to increase above market rates.

Savings & Green Energy

Many customers have been able to save on fixed rate electricity plans. In addition, consumers are pleased that they can make an environmentally friendly option - all electricity plans with Green Mountain Energy are 100% renewable. Some are impressed that the quality of electricity on a renewable plan is exactly the same as traditional sources.


In 2008 and  2014 Green Mountain Energy won the highest award for Texas customer satisfaction among retail electricity suppliers from JD Power & Associates.

The company has an A+ rating from the Better Business Bureau based on excellent resolution of customer concerns. Additionally, Green Mountain Energy receives a low number of formal complaints compared to its size.

Hidden Fees

Customers express disappointment with fees to start service. Additionally, some customers sign up for fixed rate plans without being fully informed of early cancellation fees

High Prices on Variable Rates

Customers on variable rate plans are often upset about the instability - and tendency to increase - of variable rate plans. Rates are marketed as being linked to the market price of electricity. In practice however, many customers report that prices end up far above their local utility.

Unpleasant Sales Techniques

Some customers report poor customer service experiences, with long wait times and sometimes abrasive service.

Additionally, consumers are not happy with Green Mountain Energy's door to door and street sales practices. There are allegations of rude behavior among salespeople.
