Siouxland Energy was formed to build, own, and operate an ethanol plant near Sioux Center, Iowa.

The ethanol produced from corn is sold for blending with gasoline as an octane enhancer and as a fuel. In 2007 Siouxland Energy completed an expansion project that increased production capacity to 60,000,000 gallons annually.

Within the last couple of years, Siouxland Energy has completed several debottlenecking and carbon intensity projects that allow the production of a low carbon fuel at a production pace of 70,000,000 gallons per year.


Siouxland Energy Cooperative is owned by 385 farmer members and is a closed cooperative. We are located in the northwest corner of Iowa, just west of Sioux Center.

Sioux Center’s growth and modernization has been steady through the years, with the population growing to about 7,579 residents, according to the U.S. Census Bureau. Ideally located in northwest Sioux County, Iowa, Sioux Center is close to Interstates 29 and 90, allowing business and industry to continue to expand. Agriculture is the root of Sioux Center and strongly supports the rural population with ag-related businesses like ours.
