Aventine Extends Construction Schedule for Aurora West Ethanol Facility

PEKIN, Ill., Oct. 6, 2008 (GLOBE NEWSWIRE) -- Aventine Renewable Energy Holdings, Inc. (NYSE:AVR), a leading producer, marketer and end-to-end provider of clean renewable energy, today announced that its wholly-owned indirect subsidiary, Aventine Renewable Energy - Aurora West, LLC, and Kiewit Energy Company ("Kiewit") have agreed to modify and extend the construction schedule and other terms of the Engineering, Procurement and Construction contract for the ethanol facility currently under construction in Aurora, Nebraska.

The amended terms will not affect the total cost of the project. Payments to Kiewit will mirror the new construction schedule. No penalties will be incurred as a result of these changes. These changes should allow Aventine's other ethanol facility currently under construction in Mt. Vernon, Indiana to begin producing ethanol and operating cash flows before the Aurora West facility begins production.

Aventine Renewable Energy - Aurora West, LLC is currently constructing a 113 million gallon ethanol facility in Aurora, Nebraska. The facility's start-up, which was expected to occur in the first quarter of 2009, is now scheduled for the second quarter of 2009.

Daniel Trunfio, Chief Operating Officer of Aventine, said, "The mutually agreed upon changes to the Aurora construction project highlight the excellent working partnership between Kiewit and ourselves. Kiewit, as one of the leading construction firms in the country, has continually shown themselves to be a great partner and a first class act. This change should also help us stretch our liquidity in this unprecedented time of capital market instability." Trunfio continued, "We remain fully committed to producing ethanol at both the Aurora West and Mt. Vernon expansion projects."

Brad Kaufman, President of Kiewit Energy Company, said, "The Kiewit/Aventine relationship continues to be one of the strongest in the industry as evidenced by this latest agreement which is mutually beneficial to both companies."
