TotalEnergies, Schneider Begin Construction of Keyes Plant Solar Microgrid


Eric McAfee

Construction has begun on a TotalEnergies and Schneider Electric solar microgrid system with a 2 MW photovoltaic array and a 1.25 MW battery energy storage system. Once development has been accomplished, the microgrid will probably be built-in with the brand new Rockwell/Allen Bradley distributed management system at Aemetis Inc.’s biorefinery in Keyes, Calif.

The solar array will generate roughly 3.2 million kWh per 12 months. Foundations for the solar array at the moment are below development, with venture completion anticipated within the second quarter of 2023. TotalEnergies serves because the venture’s PV provider in addition to the engineering, procurement and development contractor.

“The microgrid creates energy resiliency and will assist with off peak load shedding and energy efficiency,” states Eric McAfee, chairman and CEO of Aemetis. “This microgrid, along with other energy saving technologies being implemented at our low-carbon ethanol facility, will further reduce the carbon intensity score of the fuel ethanol produced. Aemetis can also displace natural gas with carbon negative renewable natural gas upgraded and injected at the same facility in Keyes, Calif.”

The AI-enabled management system will run on virtualized servers, decreasing the quantity of laptop {hardware} by 80%, which would require much less power to function than conventional methods. Virtualized methods don’t require altering {hardware} to improve obsolescent working methods or safety modifications. The digital atmosphere may also assist cut back deliberate and unplanned down time.

The $12 million solar microgrid, battery backup and AI-enabled energy system is supported by an $8 million grant awarded to Aemetis by the California Energy Commission.
