Installing a rooftop solar system will help you save on energy costs for years to come, and with Renewable Rewards, you’ll be credited when you produce more energy than you use. You’ll also significantly lower your home’s carbon footprint and help ensure a cleaner, greener future for the planet.
The Renewable Rewards Buyback Program is available to new and existing residential customers in Texas who:
Yes. You’ll need a meter configured by your utility that separately measures the inflow and outflow of electricity to and from your home. Your utility may charge for this meter, and these charges would be passed through to you on your Green Mountain Energy bill.
Yes! Both current and new Green Mountain Energy customers who meet the program requirements listed above can enroll in a Renewable Rewards buyback plan. If you’re a current customer enrolled in a plan with a cancellation fee, we will waive that fee if you would like to switch to a Renewable Rewards buyback plan, assuming all the requirements are met.
The Renewable Rewards Buyback Program is available to new and existing residential customers in Texas who have installed home solar or small-scale wind systems with a capacity of 50 kW or less.
To put it simply, net metering lets you produce energy for the grid beyond what you use for your own home. With Renewable Rewards, you’ll receive a bill credit for excess energy that you’ve produced.
The electricity produced by your solar panels first powers your home. But when your panels produce more energy than you need, the remaining energy is delivered to the grid.
There are a few different terms that describe energy your solar array produces and energy your house consumes, including:
The most obvious benefit is that you’re contributing to a cleaner, greener future! Solar energy produces no greenhouse gases or other waste. Any extra energy you produce can also be stored on a backup battery or sent back to the grid.
We buy back the energy that your solar panels deliver back to the grid. Your excess energy credits will show up on the second page of your electricity bill on the “Renewable Rewards Credit” line:
You can enroll at any time, but to ensure that you receive credit for your excess solar energy as soon as possible, we recommend setting your enrollment date to be the same day you expect to receive Permission to Operate (PTO) from your utility. You can set your enrollment date for a Renewable Rewards buyback plan up to 60 days in advance.
It can take up to three billing cycles after you receive Permission to Operate (PTO) and are signed up on a Renewable Rewards buyback plan before excess energy credits appear on your bill. Both Green Mountain Energy and your utility must make system changes to process your excess energy readings, and these changes take time to complete.
There are a few steps to take if you are not receiving excess energy credits:
Yes. A Renewable Rewards customer’s existing credit balance carries over if they swap to a different plan with Green Mountain Energy.
Both your energy usage and solar production vary each month because of factors such as:
Existing Green Mountain Energy customers in Texas can enroll by calling us at 1-866-785-4668 to switch their electricity plan to a Renewable Rewards buyback plan.
New customers in Texas can enroll in a Renewable Rewards buyback plan online, or by calling us at 1-866-301-3120.
If you have questions about your electricity bill or plan, call Green Mountain Energy at 1-866-785-4668.
If you have questions about your solar panels or don’t think your system is producing as much power as it should, contact your installer.

The Renewable Rewards Essential plan allows homeowners with rooftop solar panels to sell excess electricity back to the grid and receive credits on their energy bill, up to their monthly energy usage from the grid.
Homeowners with a rooftop residential solar panel system installed on their home who want to sell their excess electricity back to the grid.
When your solar panels produce more electricity than you use, the extra energy is sent to the grid. You'll receive a credit for this energy, but only up to the amount of energy you consume from the grid in a billing cycle. Delivery charges, base charges, taxes, and other fees are NOT included in the credit.
Yes. Credits are limited to the amount of energy you consume from the grid during the billing cycle. Energy sent beyond your monthly usage will not earn additional credits.
Your excess energy credits will appear on the second page of your electricity bill under the “Green Mountain Energy Renewable Rewards Credit” line.
The bill credit rate matches the energy charge rate of your plan. It does not include delivery charges, base charges, taxes, or other fees. Credits are applied up to your grid energy usage for the billing cycle.
Yes, standard charges such as delivery charges, monthly base charges, taxes, and other applicable fees are not covered by the credits and will still apply to your bill.
If your energy consumption from the grid exceeds the credits you’ve earned, you’ll pay the standard energy charge rate for the additional energy.
No, the plan does not allow for a zero-dollar or negative bill because credits are capped at your grid usage and do not apply to non-energy charges like delivery fees or taxes.
The Renewable Rewards Solar Credit plan is an uncapped solar buyback program designed for homeowners with rooftop solar panels. It gives you credit for the excess electricity your panels generate and send to the grid, helping you save on energy costs and support a cleaner planet.
Homeowners with a rooftop residential solar panel system installed on their home who want to sell their excess electricity back to the grid.
When your solar panels generate more electricity than you need, the excess energy is sent to the grid for others to use. You’ll receive bill credits for this excess energy, which can offset the charges for the electricity you use from the grid.
No, there are no limits or caps on the amount of solar energy you can send to the grid or the credits you can earn.
Your excess energy credits will appear on the second page of your electricity bill under the “Green Mountain Energy Renewable Rewards Credit” line.
The credit per kilowatt-hour (kWh) for your excess solar energy is at a lower rate than the energy charge rate for the Renewable Rewards Solar Credit plan. The exact rates are listed in your Electricity Facts Label.
Yes, base and delivery charges from your utility are passed on to your bill. These are separate from the energy charges.
No, the plan does not guarantee a zero-dollar or negative bill due to differences in energy charge rates and solar credit rates.
Yes. With our Renewable Rewards buyback plans, you receive credit for all the excess energy your solar energy system delivers to the grid. For the Renewable Rewards Solar Max plan, the rate per kWh you are credited for excess electricity is the real-time wholesale rate for your load zone, with no cap on the amount you can earn. Your excess electricity credits will show up on your electricity bill on the “Bill credit” line.
Please note that the Renewable Rewards Solar Max plan is only available for Texas residential customers who meet the plan requirements.
For each 15-minute interval:
Buyback credit amount = (Buyback rate in$/kWh) x (Excess energy delivered to the grid in kWh during the 15 min. interval)
The buyback rate is equal to ERCOT Load Zone Real Time Settlement Point Price (RTSPP) in the 15-minute interval for the customer’s load zone. If the RTSPP is less than zero for a given 15-minute interval, the credit amount will be zero for that interval.
The credit amount for the bill period will be the sum of the credit amounts across all 15-minute intervals in that period.
In the event Green Mountain Energy receives incomplete interval data from your TDSP, Green Mountain Energy may estimate your outflow kWh for missing periods based on the monthly meter read reported by the TDSP. When there is a difference in outflow kWh between the monthly meter read and the monthly total of the interval data, the difference will be allocated over missing intervals and the estimated outflow kWh will be used to calculate credit amounts applied to your bill.
No, there are no caps on excess electricity credits. Customers enrolled on the Renewable Rewards Solar Max plan that meet the eligibility requirements will receive credits for all excess electricity delivered to the grid. If the credits exceed the charges on your monthly invoice, the remaining credits will carry forward to the next month.
See the map below to find your ERCOT 15-minute RTSPP load zone.
Your Renewable Rewards Solar Max buyback plan bill shows:
Both your grid usage and your excess energy are measured by the meter installed by your utility. The bill does not show your total solar production, which may be measured by your solar monitor. This is because some of the solar power is immediately used by your house and never flows to the grid.
You can download your excess energy export data from your Smart Meter Texas account or request a paper copy by calling a Solar Call Center Specialist at 1-855-465-5061.
