Nacogdoches Generating Facility

Location: Sacul, Texas
Current Capacity: 100 megawatts
Ownership: Southern Power
Fuel Resource: Biomass

Southern Company built the largest wood biomass power plant in the United States. The Nacogdoches Generating Facility, which began commercial operation in June 2012, is a 100-megawatt biomass-fueled base-load facility providing enough power to supply approximately 60,000 homes with electricity. The plant is owned and operated by Southern Power, a subsidiary of Southern Company. Southern Power is a wholesale energy provider and focuses on helping its customers meet their energy needs in a cost-effective, reliable and environmentally responsible manner.

Located near Sacul in Nacogdoches County, Texas, the plant is serving a 20-year contract with Austin Energy to help meet the state's Renewable Portfolio Standard, with the output serving the City of Austin.

Southern Company continues to develop and deploy smarter and cleaner energy technologies, including increased energy efficiency, nuclear power, clean coal and renewables. Nacogdoches represents another step in developing a diverse portfolio to meet the nation's growing energy demands.

The site of the facility, which was construction-ready upon purchase, was acquired from American Renewables in 2009.


The plant is capable of generating approximately 100 megawatts of electricity and is one of the largest biomass plants in the United States.


The plant consists of a bubbling fluidized bed boiler, a condensing steam turbine generator with an evaporative cooling tower, wood fuel handling system and auxiliary support equipment. The plant is fueled with biomass materials, including forest residue from the surrounding areas, wood processing residues and clean municipal wood waste.

Approximately 1 million tons of fuel are required annually, and are procured within a 75-mile radius of the project site.

Economic Impact

The Nacogdoches Generating Facility is expected to produce millions of dollars in economic benefits through job creation and property taxes for Nacogdoches County and the surrounding Texas market.
