The U.S. Department of Energy and the North Carolina Clean Energy Technology Center are excited to announce that a new, modernized DSIRE is under construction. The new version of DSIRE will offer significant improvements over the current version, including expanded data accessibility and an array of new tools for site users. The new DSIRE site will be available in December 2014. Staff are currently working hard on the new version of DSIRE but are also maintaining the content of the current version of DSIRE. Thank you for your continued support and patience during this transition. We hope you are as excited for December as we are!

Texas does not have statewide net metering as the term is generally understood. However, retail electricity providers in Texas are permitted, but not required, to compensate customers for electricity produced by distributed renewable energy generation systems and exported to the electric grid. The program described below operates in a fashion similar to net metering and has similar customer benefits up to a certain point.

Eligibility and Availability

Green Mountain Energy Company, a retail electric provider of green electricity in Texas’s deregulated electricity market*, offers a special Renewable Rewards buy-back program to Texas customers who generate electricity from renewable sources using distributed generation systems. The offer is only available to residential and business customers of Green Mountain Energy Company who purchase electricity under the company's Renewable Rewards product.

The arrangement requires the customer to enter into an interconnection agreement with their electric distribution utility (i.e., an entity different than Green Mountain Energy, which is a retail electric provider). The customer must also work with their distribution utility to install a meter capable of separately measuring the flow of electricity in both directions. Visit the program website to find utility interconnection contacts.

Eligible Technologies

Wind, solar, geothermal, biomass (and related technologies), hydroelectric, wave, and tidal energy systems are eligible to participate in this program.

Net Excess Generation

Under the program, systems are installed on the customer's side of the meter and may provide a portion of the customer's on-site electricity demand. Any net excess generation (NEG) produced by the customer’s system that is exported to the grid is metered separately, and the customer's account is credited the following month for the exported energy. The amount of the credit for residential customers is as follows:

  • the customer-generator is credited at the retail rate of the Renewable Rewards electricity product the first 500 kilowatt-hours (kWh) of NEG in a month, and
  • the customer-generator is credited at 50% of retail rate of the Renewable Rewards electricity product for any NEG in excess of 500 kW.

The customer continues to pay the retail rate charged by Green Mountain under the Renewable Rewards program for all the electricity they consume from the grid during a month, as well as any applicable monthly service charges, advanced meter surcharges, taxes and fees, or other charges. Notably, customers retain title to any renewable energy credits (RECs) or other environmental attributes produced by the system.

For business customers, Green Mountain Energy will credit their monthly invoice equal to the excess energy they generate multiplied by the contracted energy rate on their Green Mountain Energy electricity contract. The maximum capacity for a business customer’s grid-connected renewable energy system is 50 kW.


*  Texas’s deregulated electricity market spans the vast majority of the state, including the cities of Houston, Dallas, Fort Worth, and Arlington. Austin and San Antonio, which have municipal utilities, and El Paso, which is serviced by a regulated investor-owned utility, are notable exceptions.
