Dynamic Energy is excited to work with American Yeast and BG&E on this significant biogas-fueled Combined Heat & Power project. American Yeast's investment in CHP will pay dividends for many years.

Michael Perillo, CEO


Dynamic Energy has begun construction on a 400 Kilowatt, biogas-fueled, Combined Heat & Power (CHP) co-generation system for American Yeast, a food-processing subsidiary of Lallemand, Inc., located in Baltimore, Maryland.  The CHP project will utilize a Caterpillar engine designed specifically for biogas applications.  The site’s wastewater plant and associated anaerobic digester will provide biogas to run the CHP system full time.

Dynamic Energy was awarded a $450,000 incentive from Baltimore Gas & Electric for the facility.  This CHP project will generate over 3,200,000 kWh of electricity annually for American Yeast, displacing over 30% of electricity usage and reducing demand charges at the Maryland site.  The daily process will also utilize 100% of the thermal energy produced by the 400 kW CHP system for process hot water and plant cleaning purposes.  The hot water provided by the CHP plant will provide a substantial load reduction for the existing boilers.  The combination of available biogas fuel, rebate, electricity savings and thermal savings has resulted in less than a 2 year simple payback for American Yeast.
