Mt. Vernon is home to a number of refineries and also a former GE Plastics Plant, now owned by Saudi Arabia Basic Industries Corporation (SABIC). Vectren Energy's A.B. Brown Generating Station is also addressed to Mt. Vernon. The Ports of Indiana are negotiating with a second biofuels company to develop a plant at the Port of Indiana-Mount Vernon. The new facility, along with the Aventine Renewable Energy ethanol plant announced late last year, will make Mount Vernon an important energy port. The Aventine plant, which is being developed by a partnership with Consolidated Grain and Barge, another company at the port, will be the largest ethanol plant east of the Mississippi River. It is expected to produce 110 million gallons of ethanol a year by Sept. 2008. The Mount Vernon port is also the largest port for coal shipments in the U.S.
