Aemetis is a renewable natural gas and renewable fuels company focused on low and negative carbon intensity products. On a mission to reduce greenhouse gas emissions while also lowering energy costs associated with facility operations, Aemetis invested in a 3 MW solar microgrid with battery storage for the company’s ethanol plant in Keyes, California.
The California Energy Commission provided Aemetis with a grant for the project, which included a solar array developed and installed by TotalEnergies as well as electrical and battery storage equipment from Schneider Electric.
The battery, which features an AI energy management system, further helps reduce the amount of grid electricity purchased during the high-cost peak periods in the late afternoon and early evening by capturing and storing solar energy during mid-day, then delivering the electricity from the battery storage system back to the plant during peak hours.
“This large integrated solar and battery storage system is a key step in the conversion of the Keyes ethanol plant to renewable electricity from petroleum natural gas,” stated Eric McAfee, Chairman and Chief Executive Officer of Aemetis, Inc. “We appreciate funding support from the California Energy Commission, as well as the positive working relationship with TotalEnergies as the general contractor during design, construction, and commissioning.”
