Green Plains Renewable Energy, Inc. Nears Completion of Ethanol Plant in Superior, Iowa

Green Plains Renewable Energy, Inc. (NASDAQ: GPRE) (AMEX: GPRE) announces that construction of the ethanol plant in Superior, Iowa, is nearing completion, and commencement of production is imminent. The plant, which is expected to be operational in July, is fully staffed, receiving grain, commissioning equipment and testing process systems.

"The Superior ethanol plant is a state-of-the-art facility," said Wayne Hoovestol, Chief Executive Officer. "With approximately 40 employees and a significant corn procurement requirement, the plant will have a profound impact on the local economy. We greatly appreciate the continued efforts of the local officials, contractors, engineers and employees who worked on this project. We are proud to be a part of Iowa's expanding renewable energy economy."

Once operational, the Superior plant will have an expected operating capacity of 55 million gallons of ethanol per year. Additionally, the plant is expected to produce 175,000 tons of distillers grains. The ethanol plant will process approximately 20 million bushels of corn annually. The facility is strategically located in close proximity to 16 million bushels of grain storage owned by Green Plains Grain Company, a wholly-owned subsidiary.

"In addition to ethanol production, Green Plains is vertically-integrated with grain storage and merchandising, agronomy, feed and petroleum businesses," continued Hoovestol. "The consolidation and integration of these businesses helps to increase efficiency and manage commodity price and supply risks. The Superior plant and Green Plains Grain Company will work closely with local producers to develop innovative strategies for creating new opportunities in the ethanol value chain."
