A History of Austin Energy

A Vision for Austin

Austinites have owned their electric utility for nearly 125 years. Austin was a small town then, but now it’s one of the largest, most vibrant and cutting-edge cities in America.

Throughout the decades, our community has always seen its electric utility as a source of business development and affordable power. Austinites’ belief in the value of owning their utility — now known as Austin Energy — has paid off in big ways. Austin Energy has generated more than electricity — it’s helped pay for city services like parks, swimming pools, libraries, police and firefighters. Austin Energy is also considered a leader in energy efficiency, renewable energy, green building, electric vehicles, and more.

For more than a century, the citizens of Austin have helped create a community-owned utility that lights our city and builds our future.

  • May 5, 1890

    Austinites vote to build waterworks and hydroelectric powerhouse on the Colorado River.

    In 1890, Austinites were fed up with what they considered high prices and poor service from the city’s privately-run water and electric company. Later that year, voters passed a bond election to build a hydroelectric dam and powerhouse to create a more controlled water supply and a source for generating electric service. Those voters believed that a utility owned by the community would help keep prices down and bring jobs to Austin.

    Austin Dam is completed.

    In 1893, the Austin Dam, designed to tame the unpredictable Colorado River, was completed. At the time, it was one of the tallest dams in the country. The lake, which subsequently formed behind the Austin Dam, was named Lake McDonald to honor Mayor John McDonald, who had helped build community support for the project.

    31 Moonlight towers are lit for the city's first electric street lighting system, establishing City of Austin electric utility.

    By 1895, the City of Austin had completed its proposed water and electric distribution systems. On May 6, 1895, switches were thrown to illuminate the now-iconic moonlight towers — 31 in all — a truly historic way to mark the start of the city’s electric utility. A celebration was later held on July 4, 1895 to officially dedicate the utility.

  • April 7, 1900

    Austin Dam breaks.

    Unfortunately, the Austin Dam was built on unstable soil and the flows from the Colorado River did not create the amount of steady hydroelectricity needed for industry. It did not bring the type of manufacturing businesses the citizens had wanted.

    Because of the poor site, questionable construction materials and inadequate planning, the dam broke on April 7, 1900. Raging floodwaters destroyed the powerhouse and knocked out electricity and water service for months.

  • April 1900

    City leaders reject sale of utility.

    The private water and electric company offered to buy the City of Austin’s systems and provide water and electricity to the citizens. But Austin’s leaders saw the benefits of owning their own systems and rejected plans to go back to private ownership.

    Instead, Austin leaders ordered steam generators be shipped to Austin to help restore water and electric service.

  • 1900s

    City mired in debt due to dam failure.

    The cost of building the Austin Dam and powerhouse, combined with revenue shortfalls suffered from the dam’s collapse, put city government in poor financial shape for years. Many services such as street paving were delayed and city government was forced to provide money to the utility to keep it operating.

  • 1927

    Walter E. Seaholm beats private company in test proving city could run utility more efficiently.

    Austinites continued to have faith in their utility and in their shared vision of a community-owned system.

    In 1901, three of four Austin City council members who voted against funding the utility were swept out of office by voters. In 1927, an offer to purchase the utility was made by a private company, Texas Power and Light Company. TP&L claimed it could run the utility better than the city. But Walter E. Seaholm, Superintendent of the City’s Electric Department, challenged TP&L to a test, and Mr. Seaholm was successful in proving that Austin could run its utility more economically and efficiently.

  • 1930s

    1930s growth fastest of 20th Century.

    Austin suffered the effects of the Great Depression but because of the presence of state government and the University of Texas, did better than much of the country.

    The city’s population boomed during the 1930s and experienced its fastest growth of the 20th century, from 53,120 in 1930 to 87,930 in 1940. The University of Texas at Austin enrollment nearly doubled, and Robert Mueller Municipal Airport opened in 1930. A decade later, Del Valle Army Air Base opened, later named Bergstrom Air Force Base after Captain John Bergstrom, the first Austinite killed in W.W. II.

    Scarbrough Building first retail store west of Mississippi with air conditioning.

    In 1931 the Scarbrough Building, Austin’s first “skyscraper,” a full eight-stories tall, became the first retail store west of the Mississippi with air conditioning. Along with the Littlefield Building — which at nine stories was the tallest building between New Orleans and San Francisco when completed in 1911 — helped form the city’s business district.

  • 1935

    1935 flood knocks out water and power service.

    There were attempts to rebuild the dam and a privately-funded effort completed repairs in 1915, but another flood that year damaged the dam once again and private investors abandoned the project.

    In 1935, another major flood knocked out water and power service to the city. Walter E. Seaholm, now the Director of Utilities, made his mark in Austin one more time by patching into TP&L’s system for electricity and established an emergency drinking water pump.

    Lower Colorado River Authority builds Tom Miller Dam.

    In 1940, the Lower Colorado River Authority (LCRA) built Tom Miller Dam — named for Mayor Robert Thomas (Tom) Miller — atop the remains of the two previous Austin Dam structures. Lake McDonald behind the dam was renamed Lake Austin.

    The LCRA was formed as a public agency in 1934 by the Texas Legislature to manage the lower Colorado River by reducing damage from flooding and providing a stable water supply. The LCRA built a system of six dams and lakes — known as the Highland Lakes — between 1938 and 1951, effectively controlling the worst of damaging floods that had plagued residents in Austin, while providing electricity to the rural regions of Central Texas that private utilities refused to serve.

    Post-World War II growth increases demand for electricity.

    After World War II, Austin’s larger population and lifestyle changes created a greater demand for electricity: washing machines, dishwashers and televisions were becoming more common and air conditioning was widely installed in homes and businesses.

    The utility’s electric peak demand — the hottest part of the summer, resulting in the greatest use of electricity — grew 325% from 19.2 megawatts (MW) in 1945 to 81.6 MW in 1955.

  • 1948

    Seaholm Power Plant gets constructed.

    In 1948, the City of Austin commissioned the Seaholm Power Plant, referred to as Power Plant No. 2 at the time, to meet the post-World War II growth and demand for electricity.

    The power plant structures were constructed in two phases — 1950 and 1955 — on the north shore of what is now Lady Bird Lake, just west of a city-owned steam plant. The three buildings on the site — the Turbine Generator Building, Water Intake Structure and Oil Heating Plant – were built with solid concrete construction and decorated in Art Deco style.

    Although it was not a local firm, the selection of Kansas City-based Burns & McDonnell to design the power plant reflected Austin’s values of public ownership of electric utilities. Co-founder Robert E. McDonnell believed that public ownership was the way to guarantee quality service over profits and he also believed that the money generated by public power plants should stay in communities to help pay for public services.

    Growth reflects expansion of education and government in Austin.

    Austin’s growth during the 1950s and 1960s reflected the expansion of education and government in the city.

    During the 1960s, the number of students attending the University of Texas doubled and between 1950 and 1970 the number of government employees working in Travis County tripled. The City of Austin population grew by 40% between 1960 and 1970 from 185,545 to more than a quarter-million residents.

    Holly and Decker Creek power plants built to keep up with growth.

    To keep up with this growth and demand for electricity, the Holly Street Power Plant in East Austin was constructed in phases between 1958 and 1974.

    Longhorn Dam — named for the longhorn cattle that once crossed this location in the late 19th century as part of the Chisolm Trail — was completed in 1960. A newspaper reporter dubbed the resulting reservoir behind the dam as ‘Town Lake,’ because the lake had not been given a name.

    Between 1967 and 1978, the electric utility also developed the Decker Creek Power Station in Northeast Austin. The natural gas plant added 927 MW of generation capacity.

    In 1967, Mayor Pro Tem Emma Long lit the Zilker Tree in Zilker Park for the first time (now an annual tradition marking the start of the winter holidays).

    Crews with the electric utility hang 39 streamers with multi-colored lights and install two stars on top of one of the 17 remaining moonlight towers to create the Zilker Tree.

    Over the years, the Zilker Tree has become an iconic part of Austin’s culture and traditions and is closely associated with Austin Energy’s passionate community involvement.

    Austin emerges as a hi-tech center.

    In the 1970s, Austin’s growth was fueled by its emergence as a center for hi-tech.

    Supported by research programs at the University of Texas, the city’s growth as a technology center increased when IBM, Texas Instruments and Motorola opened facilities. The 26-story Austin National Bank at 515 Congress Avenue opened in 1975 and was the Austin’s tallest building until 1984.

    The City of Austin’s population grew 37% — from 251,808 in 1970 to 345,890 in 1980.

    Community members beautify Town Lake.

    Influential community members led by Lady Bird Johnson, Les Gage and Ann Butler formed the Town Lake Beautification Committee in 1971 to beautify Town Lake and its shores.

    Years of flooding, and misguided efforts to remove trees and shrubs to limit damage, left the shores with little greenery. The Committee planted more than 3,600 trees — many of them colorful redbuds similar to those in Washington, D.C.

    The Committee also built a 10-mile trail (now known as the Ann and Roy Butler Hike and Bike Trail) and oversaw the construction of gazebos on Auditorium Shores and Lou Neff Point.

    Beautifying Town Lake — renamed Lady Bird Lake in 2007 in honor of the former First Lady — later became part of downtown’s economic revival and an attraction that brings employers, residents, the entertainment industry and an active lifestyle to the city’s central core.

    Moonlight towers listed on National Register of Historic Places.

    Austin’s moonlight towers were literally its first street lighting system. Austin’s 17 remaining towers, part of the original 35 first lit in 1895, were listed on the National Register of Historic Places in 1976.

    Although many other cities had moonlight towers, Austin is the only city in the world that still has working moonlight towers. Because of their architectural and historic significance in Austin, protecting the moonlight towers is a priority for citizens and city government with funding approved over the years to restore and keep them functioning.

    City becomes partners in Fayette Power Project and South Texas Nuclear Project.

    In 1979 and 1980, two coal-fired units co-owned by the city electric utility and the Lower Colorado River Authority began operating in La Grange, Texas. The Fayette Power Project added 598 MW of capacity to Austin’s system.

    During the 1970s and 1980s, the city utility teamed with other partner electric utilities in the state to develop the South Texas Nuclear Project. The controversial plant was plagued by protests from anti-nuclear groups and project delays that led to massive cost overruns.

    City establishes energy efficiency programs.

    After the energy crisis of the 1970s, the electric utility began offering energy efficiency rebates to customers to conserve energy and lower electric bills.

    Because of Austin’s emphasis on conservation and protecting the environment, the energy-efficiency programs would garner national attention and became a model for the federal government’s ENERGY STAR program.

    In 2017, Austin had the lowest average residential rates and consumption of any major utility in the Electric Reliability Council of Texas, the state’s main electric grid.

    Austin Convention Center opens downtown.

    The Austin Convention Center opened in 1992 after civic leaders believed Austin was being passed over for major conventions because Palmer Auditorium – the city’s main venue — was too small.

    The convention center became the unofficial home for SXSW — the internationally acclaimed music, multimedia and film festival — that draws hundreds of thousands every year from throughout the world.

    In 2002, work was completed on expanding the convention center to almost double its size. The Austin City Council changed the name of the center in 2004 to the Neal Kocurek Memorial Austin Convention Center to honor the late Dr. Neal Kocurek who help build community support for the original construction.

    Citizens achieve their vision.

    Austin citizens own their electric utility. They shape its vision, just as they have for nearly 125 years. Austinites overcame hardships and challenges — from ravaging floods that nearly destroyed the utility’s infrastructure to political ploys by private companies keen to purchase the utility from the city.

    The citizens’ involvement has helped create one of the largest and most successful community-owned, electric utilities in the country. In many ways, Austin Energy is a reflection of the values and vision of the community it serves.

    In 1890 when Austin citizens passed the bond election to create their own municipal electric system, they wanted to keep rates low, attract industry and jobs to the city, and improve the quality of life in the community. These forward-looking citizens helped create the city and culture that we now cherish.
