San Carlos Bioenergy is operating the integrated ethanol distillery and power cogeneration plant which has a capacity of 125,000 liters of ethanol a day and can generate about 8 megawatts of power. The plant is located in the San Carlos Agro-industrial economic zone located in the eastern coast of Negros Occidental.

The plant is expected to commence full operations in April 2009. The first drop of ethanol was recorded on January 2009, with the first batch of ethanol or around 1.7 million liters to be delivered to Petron.

In 2006, DBP, along with four other banks, signed a PHP1.778 billion syndicated term loan agreement to finance the development of the San Carlos Bioenergy bioethanol fuel plant. The project was in response to the Biofuel Act in Congress, which calls for the blending of bioethanol fuel with gasoline to reduce negative environmental impact caused by fossil fuels and further support the agricultural sector.
