Aemetis Inc. announced an energy efficiency upgrade at its 65 million gallon per year ethanol plant in Keyes, California, with the integration of a Mechanical Vapor Recompression (MVR) system. The $30 million project involves equipment supplied by Praj Industries and project execution by NPL Construction Co., a subsidiary of Centuri Holdings. The upgrade is intended to reduce the carbon intensity of ethanol production and improve operational efficiency. According to the company, the project leverages regulatory programs such as the Low Carbon Fuel Standard (LCFS) and Section 45Z production tax credits. The initiative has received approximately $19.7 million in grants and tax credits from the California Energy Commission, Pacific Gas & Electric, and federal Section 48C tax credits.
