Cogeneration and District Solutions

It has been estimated that about 20 percent of U.S. electricity could be made with heat that is currently wasted by industry. Gain an overview of micro-cogeneration and district energy solutions for commercial and district applications. Learn about cogeneration system selection and sizing, preliminary feasibility study approaches, heat to power ratios, computer programs, economic and environmental issues, emerging technologies and regulations. Explore the economics of micro-cogeneration life cycle assessment, breakeven analysis, incentive programs, heat and electricity supply scenarios, and interconnecting with your local utility. Examine environmental impacts such as co-products, impact assessments and pollutant emissions.


Doug Williams is a registered mechanical engineer who specializes in anaerobic “oxygen-free” digestion, biogas energy utilization, energy conservation and farm machinery systems. He is owner and principal engineer of Williams Engineering Associates. He has served as a project manager and design consultant for several covered-lagoon-type digester projects throughout California including three organic dairies in Sonoma and Marin counties and three large dairies (1500 to 850 cows) in the San Joaquin Valley, which produce up to two MW of renewable electrical power. Williams served as a professor of Bioresource and Agricultural Engineering for 23 years at Cal Poly, San Luis Obispo where he originated and taught Energy for a Sustainable Society, an upper division course about all types of renewable energy including biomass, wind and solar.
