The Hackberry Wind Farm Project is a US $350 million wind farm in Shackelford County, Texas. The project consists of 72 Siemens wind turbines with a total capacity of 166 megawatts. The energy will be used by residents of the City of Austin and surrounding communities. Construction on the project began in January 2008 and was finished in December 2008, on-time and under budget.

RES Americas is the developer, construction contractor, operator of the project and owner, along with GE Energy Financial Services, a unit of GE, according to a company news release. Austin Energy will purchase the power produced by Hackberry, moving Austin closer to its goal of securing 30 percent of its electricity from renewable sources by 2020.

RES Americas has been active in the US market since 1997 and has played a major role in developing more than 12% of the operating wind projects in the United States and more than 20% of the installed wind capacity in the State of Texas.
