). 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. 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. 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. 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 – is anticipated to allow the city to avoid $275 million in additional costs.

Criticism

Austin energy has been criticized for increasing energy prices to fund renewable energy projects and for the 2011 rolling blackouts. It has also been criticized for its handling of the texas freeze in early 2021. Critics have called Austin Energy a "monopoly", since Austin didn't follow suit in the deregulation that approximately 1/3rd of Texas cities have been part of.
