OMAHA, NE, Jul 30 (MARKET WIRE) --
Green Plains Renewable Energy, Inc. (NASDAQ: GPRE) commenced operations
at its recently-acquired ethanol plant in Central City, Nebraska on July
29, 2009. Green Plains anticipates production of ethanol by August 2nd.

"The Central City plant is on-line and operational after we made some
necessary repairs and capital improvements to the plant," said Todd
Becker, Green Plains' President and Chief Executive Officer. "The
improvements will allow us to operate more efficiently, producing 100
million gallons of ethanol annually. The Central City plant has been idle
since November 2008 and, again, our team's knowledge of the process
technology and execution of our start-up plan allowed us to quickly put
this plant back into production after completing the acquisition."
