                               Filed by Green Plains Renewable Energy, Inc.
                           Filed Pursuant to Rule 425 promulgated under the
                                        Securities Act of 1933, as amended.

                      Subject Company:  Green Plains Renewable Energy, Inc.
                                             Commission File No.: 001-32924
Green Plains Renewable Energy, Inc. (NASDAQ: GPRE) (AMEX: GPRE) today announced that it has entered into a definitive merger agreement with Great Lakes Cooperative headquartered in Everly, Iowa. Under the merger agreement, Great Lakes' members will receive cash and Green Plains' common stock valued at approximately $20 million. Created in 2001 from the merger of two longstanding northwest Iowa cooperatives, Great Lakes is a member- owned cooperative that operates one of the largest networks of grain elevators in Iowa.

Great Lakes operates a federally-licensed public grain warehouse; provides grain marketing services; and supplies feed, fertilizer, chemicals, petroleum and other products primarily in northwestern Iowa and southwestern Minnesota. The company has approximately 100 employees and 14.5 million bushels of grain storage capacity at its seven sites in northwestern Iowa, including four locations with mainline rail facilities. Green Plains' second ethanol plant is currently under construction less than one mile away from and on the same rail line as Great Lakes' Superior grain facility. Grain from Great Lakes' elevators will be used for Green Plains' ethanol production as well as marketed locally and throughout the United States.

Closing of the transaction is subject to, among other things, approval by Great Lakes' members. Green Plains will be required to file a registration statement with the Securities and Exchange Commission ("SEC") in connection with the proposed merger. Information meetings for Great Lakes' members will be held after the registration statement becomes effective. Upon closing, Green Plains will issue approximately 451,000 shares of common stock and $12.5 million in cash to Great Lakes' members. Great Lakes' investment in other regional cooperatives, with a current book value of approximately $11.3 million, will be placed in an escrow account for its members and excluded from the merger.

Wayne Hoovestol, chief executive officer of Green Plains, said, "This merger provides immediate liquidity to Great Lakes' shareholders and vertical integration for Green Plains. We believe Great Lakes' business relationships, workforce and grain-receiving locations are an excellent fit with our need for significant quantities of corn for our ethanol production. Great Lakes' other operations effectively serve their communities and we plan to continue those services in the future. The Great Lakes' owners will add a new group of stakeholders to Green Plains with a long-term vested interest in our success. We are committed to do everything we can to continue to earn their business."

"Merging with Green Plains became the logical alternative as we explored different ways over the past two years to originate grain for their Superior ethanol plant," said Kevin Adolf, president of Great Lakes Cooperative. "Ethanol production is dramatically changing agriculture and this merger positions our owners and our employees to directly participate in new and exciting long-term opportunities. At closing our owners will receive a significant amount of cash and Green Plains' stock, and in future years they will receive substantial payouts from our regional equity investments."
