Prime Location

Marquis Energy draws on its superior location in Hennepin, Illinois to produce and distribute its renewable fuels products across the world.

Situated in the heart of the Corn Belt, our site takes advantage of the surrounding area’s abundant corn supply as the facility’s feedstock. Marquis draws corn from eighteen counties, which produce over 600 million bushels per year.

Marquis Energy also capitalizes on geographical advantages to capture opportunities in various markets. Few renewable fuels production facilities can match the freight transportation network available to Marquis Energy. Located near numerous state and interstate highways, truck freight moves ethanol, distillers corn oil, and distillers dried grains throughout the region, while direct Class I railroad access allows us to cost-effectively reach prime markets by rail. The facility’s most significant logistical edge lies in its location on the Illinois River.

Scale Size Efficiency

The Marquis Energy facility is two Fagen/ICM units that are fully independent yet dually redundant on one site in Hennepin, IL. At a combined capacity of over 365 million gallons, Marquis Energy is considered the largest dry-mill ethanol facility in the United States. The facility draws over 100 million bushels of corn from a 50-mile radius. In addition to producing over 365 million gallons of ethanol, the facility produces over 400 thousand tons of distillers dried grains and over 35 million pounds of distillers corn oil annually.

Strategic Growth

The Marquis’ found an opportunity to expand and improve an ethanol facility in Necedah, Wisconsin. In July of 2010, Marquis acquired the plant and began to make improvements. The plant is a nameplate 50 million gallon per year Fagen-ICM plant that was running below nameplate before our production team took over. Under Marquis’ management, the plant now runs at an impressive 95 million gallons per year.

Given the right logistics, Marquis hopes to expand their success to future projects.

Worldwide Distribution

Marquis Energy has a significant track record of shipping its renewable fuels products throughout the world. By doing so, Marquis helps contribute to the United States’ positive balance of trade with foreign nations. Process efficiencies and mechanical upgrades allow us to produce up to six grades of ethanol, including stringent low-water specifications required by international customers. Our distillers grains are in high demand around the globe because they are dried at lower temperatures, resulting in a brighter color, superior amino acid availability, and, therefore, greater absorption capability in customers’ livestock. Since production began in 2008, Marquis Energy’s ethanol and distillers grains have been distributed to over twenty-five countries across five continents.

Marquis is able to reach international destinations by taking advantage of the facility’s numerous economical freight transportation options. Direct access to a Class I railroad offers the ability to efficiently reach export terminals within the premium East Coast and Gulf Coast markets. Additionally, Marquis Energy’s location on the Illinois River provides unique access to the American inland waterway system, and, subsequently, the United States Gulf Coast’s substantial international marketplace.
