AE Biofuels Re-Starts California Ethanol Plant

The AE Biofuels ethanol plant in central California is back in production.

Subsidiary AE Advanced Fuels Keyes has restarted operations at the 55 million gallon per year ethanol production facility located in Keyes, California and hired about 50 full time employees. The company announced in March it was restarting the plant, which has been closed since 2009.

The original $130 million construction and commissioning of the plant was completed in November 2008 by Cilion, Inc. In early 2009 the plant was closed due to technical and market issues. AE Keyes took possession of the facility under a project agreement with Cilion in March 2010, signed a facility lease for up to five years, and funded $8 million of financing to retrofit and restart the plant.

The Keyes plant is a leader in environmentally responsible ethanol production with a 2.6:1 positive energy balance and near zero water discharge. In addition, the plant’s natural gas and steam powered turbine cogeneration unit generates all of the operating electric needs of the plant (4.3 megawatts), thus eliminating dependence on the state’s electrical grid.

AE Keyes was recently awarded a $1.88 million matching grant from the California Energy Commission (CEC) to accelerate the commercial implementation of AE Biofuels’ patent-pending, enzyme based, cellulosic ethanol production technology. The integrated cellulose/starch pre-commercial facility will be located near the 55 million gallon per year commercial ethanol facility. The CEC grant will enable the company to build upon prior enzyme optimization work conducted at its cellulose/starch pilot facility in Montana which was opened in 2008, and will help the State of California achieve the goals of the Low Carbon Fuel Standard (LCFS).
