Austin Energy

Austin Energy is a publicly owned utility providing electrical power to the city of Austin, Texas and surrounding areas. Established in 1895, the utility is a department of the City of Austin and returns its profits to the city's general fund to finance other city services. Austin Energy is the United States' 7th largest public utility, serving more than 500,000 customers and more than one million residents (as of 2019) within a service area of approximately 437 square miles (1,130 km2), including Austin, Travis County and a small portion of Williamson County.[1]

Energy generation

Austin Energy’s total generation capacity is more than 3,000 megawatts (MW), provided by a mixture of wind power, solar power, biomass, natural gas, nuclear power, and coal.[2] All of Austin Energy's generation is sold into the ERCOT wholesale market; all of the retail load is served by purchasing power from ERCOT.[3]

Generation assets

Austin Energy owns and operates two natural gas-fired power plants in the Austin area: the Decker Creek Power Station and the Sand Hill Energy Center. The utility also owns 50% of units 1 and 2 at the coal-fired Fayette Power Project in La Grange and 16% of the South Texas Nuclear Project in Bay City (near Houston).[2] The STNP was the subject of a binding citizen referendum (November 3, 1981) to sell Austin's part in the project. STNP went online in 1986. No council has sold Austin's STNP telling citizens that "no one wanted our 16 percent".

Renewable energy

As of July 2014, renewable energy represented roughly 23% of Austin Energy's generation portfolio, which included wind, solar, landfill methane and biomass projects.[4] The utility's 2014 generation plan indicated that it aimed to produce 50% of power from renewable sources and 75% from carbon-free sources by 2025.[5] Since that time, new green energy generation assets have rapidly been brought online. As of August 2019, green energy had jumped to 43% of Austin Energy's generation mix, and by February 2020 included 1,425.6 MW of wind turbines and 644.6 MW of solar panels.[6]

On April 23, 2019, Austin Energy reached an agreement to purchase the Nacogdoches biomass facility for $460 million. Since Austin Energy entered into the 20-year Power Purchase Agreement with the biomass facility the price of natural gas has come down significantly. The purchase – one of Austin's single largest purchases ever[7] – is anticipated to allow the city to avoid $275 million in additional costs.[8]

Energy conservation

Austin Energy operates an energy efficiency program for customers, including a free energy audit that helps to identify ways users can reduce power consumption. The utility offers various subsidies and rebates for efficiency improvements, including HVAC, insulation, efficient lighting, and photovoltaic panels.[9]

In 1992 Austin Energy developed the nation's first local Green Building program.[10] It shares the distinction of being the largest and best established green building program in the country along with Built Green Colorado in Denver.[11]

Electric vehicle program

Austin Energy’s Plug-In EVerywhere network, powered by 100% renewable energy, expanded to 186 public charging stations to help drive a two-year, 300% Austin EV growth rate. Austin Energy led a 10-county, regional effort to develop a community plan that supports the adoption of EVs and successfully deployed the first-of-its-kind EV home charging Demand Response program.
