Residential and commercial CPS Energy systems who install a new solar water heating system on their property may be entitled to a one-time rebate. Rebate amounts vary and are based on estimated annual savings by using the system up to $2,000. In the San Antonio area, the estimated rate is 60 cents per kilowatt hour. The final amount will appear on the customer's bill as a credit amount. The application process must begin as the customer seeks a quote for their system. Customers may choose from a variety of solar contractors pre-certified by CPS Energy for the installation. The rebate does not cover equipment associated with the system's operation such as batteries or motors.

Through the Residential Energy Efficiency Rebate Program, Austin Energy incentivizes residential customers to install efficient HVAC systems, insulation, windows, or small appliances certified by the ENERGY STAR initiative. Incentives are based on improvement type and the scale of the project; larger projects yield higher rebates. A bonus flat rebate of $2,400 might be applicable to certain HVAC and weatherization projects. Energy audits are required as a part of the application process. The customer may choose from a variety of Austin Energy certified contractors to install the equipment.

CPS Energy residential and commercial customers who install a solar photovoltaic system on their San Antonio property may qualify for a rebate. The rebate program is split into three tranches based on property type. Residential customers will be credited a flat rate, while commercial customers will be credited by the watt. Provisions also exist for residential buildings used for established commercial purposes. Some restrictions apply. The system capacity must be at least 1 kW AC, and the total system cost must not exceed $4 per watt. The customer must actively pursue all necessary permits as a part of the application process.

Austin Energy offers rebates to residential customers electing to install a rooftop solar photovoltaic system on their property. The current rebate amount is $2,500 and is awarded upon both system installation and completion of an educational course. Qualifying systems must have a minimum capacity of at least 3 kW DC and be interconnected to the Austin Energy grid. Customers must file for a Letter of Intent before purchasing the system and choose a participating contractor for installation. Leased systems, existing systems, and systems under third-party net metering/billing agreements do not qualify.

Austin Energy has offered all residential and commercial solar customers a Value of Solar Tariff (or VOST) since 2012, making them the first utility nationwide to offer such an incentive. VOST is the successor to net metering for solar systems with a capacity of up to 10 MW. Customers are billed for all electricity they consume, but are credited at a fixed kilowatt hour rate for all energy generated using the photovoltaic system. In 2020, this rate was $0.097 per kilowatt hour for non-demand customers and either $0.067 or $0.047 per kilowatt hour (based on system capacity above or below 1 MW) for demand-based customers. VOST rates are subject to change on an annual basis. Qualifying systems must meet all interconnection guidelines set by Austin Energy and have a minimum contract of one year. The minimum term will be longer for customers already participating in the Solar PV Rebate Program.

In June of 2000, the Austin City Council approved Resolution 000608-43 requiring any future public building construction or major remodeling projects to meet or exceed LEED Silver certification as set by the US Green Building Council. Minor renovations, expansions, and interior finishing costing at least $300,000 must also meet LEED silver certification. All non-industrial commercial buildings at least 10 years old, publi or private, must also complete energy rating audits using Energy Star metrics or Austin Energy's own local standards. The council approved revisions to the ordinance in 2007. For the LEED Silver requirement on new or major construction to be enforced, project work must include standards across all five major LEED categories and have a total construction cost of at least $2 million.

Through the Small Business Energy Efficiency Rebate Program, Austin Energy incentivizes certain commercial and non-profit customers to install efficient HVAC systems, insulation, and windows certified by the ENERGY STAR initiative. Incentives are based on improvement type and the scale of the project; larger projects yield higher rebates. Eligible customers must be on the 50 kW rate at maximum. Commercial facilities may include residential buildings converted for commercial purposes, but do not include home offices. Customers may choose from a variety of Austin Energy certified contractors to conduct the installation.

Through the Commercial Energy Management Rebate Program, Austin Energy incentivizes larger commercial customers to install efficient HVAC systems, insulation/weatherization, ventilation, lighting, and windows. Incentives are based on improvement type and the scale of the project. Bonus rebates might apply to projects under certain weatherization or add-on conditions. As a part of the application and quote process, an Austin Energy representative will conduct an efficiency audit. The final application will include technical documentation and results of preliminary and final inspections. Each customer may choose from a variety of Austin Energy certified contractors.

Through the Commercial and Industrial Rebate Program, Oncor Electric Delivery incentivizes various commercial and industrial customers undertaking energy efficiency improvement projects. Qualifying customers include businesses, governments, nonprofits, and places of worship. At present, 17 HVAC-related projects and nine lighting project types qualify for incentives, which are determined based on estimated cost savings. Inspections and measurements are included as a part of the application process. The total amount of incentive funds Oncor can award is capped, but the program is renewed annually. Additional information is available from the Oncor website.

Solar panels, wind turbines, and other related energy equipment are exempt from the state's franchise tax. (In Texas, franchise tax is the same as corporate tax and assesses both income and property together.) Qualifying systems may be used to generate electric power or energy used for heating/cooling. Devices to store or distribute energy are also exempt. Special exemptions apply to solar/wind contractors and businesses which manufacture components for renewable energy.

In 1999, Austin first adopted a local renewable portfolio standard. This policy exceeds the requirements of state objectives. The city has a long-term goal of reaching zero carbon emissions by 2030. By 2025, Austin utilities must generate at least 65% of their retail energy using renewable technology, including solar, wind, some biomass, hydroelectric, and geothermal. "Carve-out" policies require certain proportions of investment in small-scale solar energy. Compliance is measured through mandatory reporting, typically tied to incentive programs and local net metering/distributed solar tariffs. Additional information is available from the city website.

For ten years, Austin has been the largest American city to power 100% of its municipal buildings with renewable energy. In 2014, the City Council launched a new initiative to reach net-zero greenhouse gas emissions by 2050. Current areas being improved under the initiative include energy, transportation, sanitation, and industrial management. As a part of the city's broader mission, Austin Energy is currently deriving 38% of its energy from six large solar farms and eight wind farms scattered through Texas. Combined with biomass generation, total renewable capacity is equal to 2,100 MW.

TNMP's SCORE/CitySmart advisory programs cater to schools and cities needing guidance to adopt energy efficient building standards and policies. Once the institution identifies practical solutions and targets, they may be eligible for various incentives to see their ideas realized. The Commercial Solutions program serves commercial customers beyond schools and municipal governments, providing similar financial incentives and management assistance to help them adopting solar energy or other energy efficiency projects. No participant is charged a fee, and both new projects and improvements on existing energy infrastructure may qualify.

Residential Texas Gas Service customers in Austin and Sunset Valley may be entitled to a rebate if they install a new energy-efficient HVAC or water heating system, including solar water heating and HVAC systems. Customers must be on the AUST I/S, SUNV I/S, or ABIA I/S billing plans and rates to qualify. Qualifying systems should meet local, state, and federally-set energy efficiency standards and be installed by a Texas Gas Service certified contractor. Additional information is available from the TGS website or by calling (512) 974-7827.

Through the Multi-Family Energy Efficiency Rebate Program, Austin Energy incentivizes developers and managers of multi-family residences or apartment buildings to install new energy-efficient equipment. ENERGY STAR certified HVAC systems, insulation/weatherization, windows, ductwork, and lighting may qualify. Incentives are based on improvement type and the scale of the project. The application process includes walk-through inspections. Representatives may prorate or decline to offer rebates if they would not be cost-effective for the customer. Rebates will be awarded on a first-come, first-serve basis until annual funding expires.

Through the Commercial Solar PV Incentive Program, Austin Energy incentivizes commercial customers who install and use solar photovoltaic systems for on-site energy generation and consumption. Incentives are based on system performance at a rate locked for ten years, up to a maximum amount dictated by the customer's Letter of Intent. Net metering arrangements yield additional incentives for customers whose solar system has a capacity of up to 20 kW AC. Systems certified under California Energy Commission standards qualify. A minimum 20-year manufacturer warranty, including ten years on inverters and ten years on subsystems, is required. Additional information can be found on the Austin Energy website.

Beginning in 1999, the Public Utility Commission of Texas has adopted Renewable Portfolio Standards. Each iteration of the RPS sets a minimum quota for the state's renewable energy investment within certain time frames. Previous RPS standards required the state to invest in 10,000 MW of new renewables by 2025, a standard Texas exceeded in 2009. More specific standards have also been established requiring the state to invest in resources other than wind; however, these standards have not been enforced. Solar, wind, biomass, geothermal, and hydroelectric systems are among renewable sources that go toward RPS goals. Different utility companies throughout the state are entitled to equal shares of the state's investment. Texas's Electric Reliability Council prepares a compliance report each year detailing progress toward current RPS standards. Reports are available from the PUCT website.

The State of Texas allows a 100% property tax exemption on any added value arising from new solar, wind, or biomass energy systems or system components. At present, the exemption only applies to commercial properties. Qualifying systems under the tax code include any device used to produce, store, and distribute energy for on-site consumption, but the devices must be constructed on or after January 1, 2014. Assessors will determine how much may be exempt based on depreciated value under a ten-year useful lifespan. Commercial property owners may claim the exemption by filling out Form 50-123, "Exemption Application for Solar or Wind-Powered Energy Devices", from the Texas revenue department. Additional information can be found on the Texas State Comptroller website.

Through the Residential Solar Program, Oncor Electric Delivery residential customers who install a new photovoltaic system may be entitled to a rebate. The rebate may appear as a payment directly made to the customer, a credit on energy bills, or a discount from the installing solar contractor. Eligible new systems must use the Oncor grid for electric delivery, be interconnected under a timed agreement, meet all local/state/federal codes, and be installed by an Oncor certified contractor. Existing systems do not qualify. Additional information is available from the Oncor Electric Delivery website.

Since 1989, the state of Texas's LoanSTAR (Saving Taxes and Resources) program has offered low-interest revolving loans to fund energy efficiency improvements at public and certain private facilities. The program has assisted 325 clients and invested $545 million since 1985. Eligible borrowers include state government units, public school districts, public colleges and universities, and nonprofit hospitals. Payments are based on the facility's cost savings by using the new energy systems over a 10-year maximum term. Interest rates vary annually. Eligible projects include on-site renewable energy generation systems such as solar photovoltaics/water heating and small wind turbines. Smaller improvements such as energy-efficient lighting and HVAC may also be covered.

Through the Renewable Rewards program, Green Mountain Energy compensates residential and commercial customers who use renewable energy systems interconnected to the grid. Any excess power beyond the needs of the property can be "sold back" to GME for an avoided-cost rate. Qualifying renewable energy technologies include hydroelectric, wave/tidal, wind, solar, geothermal, and biomass. Renewable Rewards is not a traditional net-metering program. As GME is only a retail provider of electric services, qualifying systems must enter interconnection with an outside distributor on the independent Texas grid. The distributor will install a bidirectional meter to measure how much power is sent back to the grid, reporting the total amount to GME. GME will then credit the customer's account.

The Texas Public Utility Commission has standardized distributed generation and grid interconnection practices in the state since 1999. Texas does not use tiers to organize operational renewable energy facilities, though no interconnected system may be rated for up to ten megawatts. Systems rated for under 500 kW may be eligible for expedited permit review, while those above one megawatt are required to register as either a self-generator or power generation company. Systems are required to meet certain IEEE standards and have a minimum manufacturer's warranty. Owners may be required to install external disconnect switches or carry liability insurance beyond the warranty requirement.

Texas has adopted an energy efficiency resource standard in lieu of a typical RPS law. Private utilities may set their own annual energy efficiency goals; by law, new goals must continually exceed previous objectives. Uniquely, the standard covers both existing energy efficiency improvements and new renewable energy investment. In lieu of a credit system, compliance is measured through annual Energy Efficiency Plans sent to the state legislature. Each report outlines the utilities' objectives and itemizes applicable investments and real cost savings. Additional information is available from the Public Utility Commission website.

Through the Commercial Solar PV Rebate Program, Austin Energy incentivizes commercial customers of all sizes who adopt solar photovoltaic systems. Incentives appear as bill credits called "Performance-Based Incentives" and will vary depending on expected system efficiency and output. The typical incentive ranges from 2 to 8 cents per kilowatt hour. Certain restrictions are in force. Nonprofit institutions may qualify under the "small commercial" category, but they must fail to qualify for federal tax credits. Any "small commercial" project receiving an incentive has a maximum capacity of 75 kW. Application paperwork and current incentive tier options can be found on the Austin Energy website.

The City of Austin adopted the first edition of its Climate Protection Plan in 2007 with the goal of reducing energy usage and greenhouse gas emissions. The initial plan set goals for most buildings to reduce their energy usage by 65 - 75% by 2015. The plan also established the Austin Energy Code, a local form of energy efficiency building certification, as well as task forces who would draft recommendations on Zero-Energy Capable Homes and energy efficiency retrofits. Currently, Austin ordinances require energy conservation audits to be conducted on any residential or commercial property to be sold, with results and disclosures made to potential buyers. New homes built in the city must meet energy efficiency standards set both locally and by the International Energy Conservation Code.

Through the GreenBack program, TXU offers rebates to commercial customers for investing in long-term energy efficiency improvements. Successful applicants may use the funding they receive to build new renewable energy systems on their property or apply them to improving existing energy systems. Even simple changes such as switching to LED lights may qualify. Funding is subject to certain eligibility standards and other terms/conditions.

Beginning with the 1982 tax year, solar and wind energy contractors, retailers, and manufacturers based in Texas may be entitled to franchise ("corporate") tax exemptions. The available exemptions currently do not have ceilings. Under the tax code, wind energy systems and solar photovoltaic, water heating, space heating, and air conditioning systems qualify. All system components, including those for energy collection, transfer, and storage, qualify as well.
