Austin Energy By the Numbers

Financial Health, Reliable Service

Customer Driven. Community Focused.

Austin Energy is an enterprise of the City of Austin. Community-owned since 1895, we provide electric power and retail energy services to the Greater Austin area. The Austin City Council sets rates and terms and conditions of service. Austin Energy is part of the Electric Reliability Council of Texas (ERCOT).

Five of the nation’s 20 largest cities own their electric utilities. Only two of these cities — San Antonio and Los Angeles — are larger in population than Austin. In the United States, 2,020 public entities, mostly cities, own their electric utilities. Together, public power serves 49 million Americans.


Austin Energy earns no profits and pays no federal income taxes. All revenues benefit the customers of Austin Energy and the residents of the City of Austin. The primary financial benefit to the City of Austin is Austin Energy’s transfer to the General Fund, which is allocated by elected City Council members to municipal purposes such as police, fire and parks. The amount is set by policy and has ranged from $105 million to $110 million in recent years.

All revenues of Austin Energy come from the sale, distribution and transmission of electric power and from supplying chilled water. Revenue has increased in recent years, primarily from growth in industrial load.

Fiscal Year Operating Revenue 
2018 $1.41 billion
2017 $1.37 billion
2016 $1.38 billion
2015 $1.36 billion


We serve primarily residential customers, as well as commercial and industrial customers. Customer growth has been strong for many years. Customer growth has exceeded electric sales growth because Austin Energy incentivizes customers to reduce their electric power usage and save money.

Traditional Generation Infrastructure

Unlike many municipal utilities, Austin Energy owns and operates power plants. It owns natural gas fueled power generation facilities, and we own interests in a coal plant and a nuclear-powered plant. As with all power producers within ERCOT, all output is sold to the ERCOT market at prices set by the competitive market.     

Rated Generation Capacity
Name Type Year of Newest Unit Rating in Megawatts
Sand Hill Gas – Combined cycle combustion and gas turbine 2010 595 MW
Decker Gas – Gas turbine and steam unit 1988 944 MW
Mueller Gas turbine 2006 5.8 MW
Fayette Power Project Coal 1980 604 MW (Austin share)
South Texas Project Nuclear  1989 419 MW (Austin share)


Renewable Generation Infrastructure, Off-Site Power and Storage, and Energy Efficiency

Austin Energy is a leader in adopting innovative technologies and the use of renewable energy. Our goal in this region is to hit net-zero greenhouse gas emissions by 2050 to protect the environment.

  • Chilling Stations — Austin Energy operates three central chilling stations for air conditioning use in downtown and other high-density areas. This operation moves peak electric use to non-peak periods to save money.
  • Power Storage — In early 2018, Austin Energy installed a major 1.5-megawatt battery for distribution-level power storage from renewable and other resources.
  • Energy Efficiency — Austin Energy also has made steady progress in energy efficiency for more than three decades. Today, among entities with more than 100,000 residential customers, Austin Energy has the lowest consumption in ERCOT and the second-lowest in the state.

Transmission and Distribution Infrastructure

Austin Energy owns and operates a high-voltage transmission system to move electricity from power generation facilities to substations for distribution. The transmission system is used by Austin Energy, as well as other utilities within ERCOT, with rates regulated by the Public Utility Commission of Texas. Transmission revenue is earned from utilities within ERCOT, including Austin Energy, and not directly from retail customers.

Austin Energy’s mission is to safely and reliably distribute electricity from its substations to customers’ homes and businesses throughout the Austin area. We work around the clock to maintain the integrity of our system to ensure we deliver safe, clean and reliable power to our customers.

Transmission and Distribution Infrastructure
Transmission Lines  624 miles
Distribution Lines 11,651 miles
Transmission Substations  13
Distribution Substations  61
Utility Poles 156,359
Overhead Transformers 43,909
Pad Mount Transformers 40,459


Austin Energy spends millions a year to maintain, replace, and modernize its distribution system. Compared with other U.S. utilities, our customers experience less frequent and shorter outages. We are currently exceeding our reliability goals. 

Standard Austin Energy Goal FY 2018 Austin Energy Metrics
SAIFI — The average number of times a customer’s service was interrupted ≤ 0.72 interruptions 0.62 interruptions
SAIDI — The average duration in minutes ≤ 57.22 minutes 41.43 minutes
SATLPI — The average number of transmission line faults per 100 miles 3.0 faults 1.43 faults
