About Green Mountain Energy

Green Mountain Energy, part of the NRG Energy, sets itself apart from most providers by only selling residential electricity plans powered by “clean” sources through renewable energy credits and carbon offsets.

Based in Houston, TX, Green Mountain aims to change the way energy is generated throughout the U.S., concentrating on solar and wind production.

Green Mountain Energy plans

Among Green Mountain Energy plans are the following, though some plans may not be available in some areas. Learn more about how to choose the right energy plan here.

Pollution Free™ e-Plus 12

This 12-month fixed-rate plan is backed by electricity made from wind energy. It requires customers to enroll in electronic billing and auto pay – avoiding use of paper – within 30 days of beginning service.

Go Local Solar 12

This plan, also for 12 months, is sourced by solar energy generated in Texas. Each month, Green Mountain sets aside money on the customer’s behalf for the Green Mountain Solar Fund, which helps pay for solar-related technology, programs and projects.

Pollution Free™ All Nighter 12

Enjoy free electricity every day from 8 p.m. to 6 a.m. During all other times during the 12-month term of the plan, your electricity is sourced by wind generation, again using RECs and carbon offsets.

SolarSPARC™ 10% 12

This plan’s electricity comes from 10 percent solar and 90 percent wind energy, again powered by RECs and carbon offsets. There’s also an annual bill credit and a donation on the customer’s behalf to support Green Mountain’s ongoing efforts to boost solar energy.

Pollution Free ™

This is a month-to-month plan sourced through wind energy. It offers customers flexibility as there is no cancellation or early termination fee. The plan also rewards eligible customers with a $100 gift card.

The U.S. average rate for residential electricity as of July 2020 is 13.28 cents per kilowatt hour (kWh).

Green Mountain Energy main energy services

Green Mountain for Home

Green Mountain Energy offers fixed- and variable-rate plans for service. Variable-rate plans don’t have contracts, which offers flexibility to customers, but can be risky since rates change from month-to-month. Fixed-rate plans offer price stability but come with early termination fees if you decide to cancel your service before the end of your contract.

Green Mountain for Business

Green Mountain Energy works with small businesses hoping to reduce their carbon footprints. Plans are customized to help the businesses meet economic goals as well as environmental targets. All business plans include at least 15 percent clean energy, and the company also offers 100 percent clean-sourced plans as well.

Other Green Mountain initiatives

Green Mountain Solar Panel Fund

Green Mountain Energy works with solar-installation companies to help customers interested in their own solar systems. Certain company plans help you earn annual credits to help pay for solar-panel installation.

The company works with local communities and nonprofits to help with sustainability grants for projects promoting renewable energy, energy efficiency, and environmental stewardship.

Texas energy plan FAQs

Do the rates shown include everything?

Rates shown in Texas include all supplier and utility charges. The only thing not accounted for in the rates shown is taxes. You can learn more about Texas energy rates here.

Will I have to pay a deposit?

You might. Providers run credit checks to determine whether to require a deposit and how large it will be. If you don’t want to pay a deposit, there are some options.

Can I switch providers at any time?

If you have a month-to-month, or variable-rate, plan, you can switch at time with no penalty. If you have a fixed-rate plan, you cannot switch plans without incurring an early termination fee. The switching process is not hard. For more information, see our guide to switching.

What if I move before my contract ends?

Moving is one exception to the above rule on early termination fees. If you present evidence that you’re moving, you will not be charged an early termination fee. You can shop for a new plan up to 90 days before the move. Of course, in most cases, you also can opt to stay with your current provider. See our moving page for more information.

Does someone have to come to my home to switch providers?

Most homes in Texas are equipped with smart meters. That means a switch can be made without a technician visit to your home.

Who do I call if there’s an outage?

If you experience a power outage, you’ll need to contact your utility right away. While you purchase electricity through energy providers, utility companies manage the infrastructure such as the power lines and will restore power when there’s an outage.

Why does SaveOnEnergy run a credit check?

Running a credit check is a common practice when it comes to purchasing electricity. Most energy providers require a credit check before they are willing to offer you a plan. However, you can avoid a credit check if you choose a prepaid, no deposit plan.

What happens if I move?

If you move, you have the option to either keep your current energy provider or find a new one. Fortunately, if you move, you won’t have to pay an early termination fee. Most homes have smart meters, so you won’t need a technician to visit your home to begin service. Should you choose to find a new energy provider, you have up to 90 days to decide on one.

What is a fixed-rate plan?

If you have a fixed-rate plan, this means the rate you pay on your bill will not vary month-to-month no matter the highs and lows of the energy market. Fixed-rate plans offer stability to consumers who are looking to lock in one rate for the duration of their contract.

What is a variable-rate plan?

If your rates are fluctuating along with the energy market, that means you’re on a variable-rate plan. This means that the rate you pay each month will change based on the price of electricity. The benefit of a variable-rate plan is that your bill could go down during market lows, but it could skyrocket when there be high demand.
