A brief description of on-site renewable electricity generating devices :
The University of Iowa has operated a combined heat and power plant since 1926. The University of Iowa uses traditional feedstock and biomass to generate steam for cost-effective electricity, cooling and water treatment on campus. In 2003, the UI Power Plant pioneered a unique and innovative source of fuel, oat hulls, through a partnership with Quaker Oats in Cedar Rapids, Iowa. Oat hulls provide an economical, environmentally friendly source of fuel. The hulls are a by-product of the cereal-making process at Quaker. They are trucked to the Power Plant and co-fired with coal in the circulating fluidized bed (CFB) boiler. The biomass fuel project supports the 2020 Sustainability Vision - Task 2. The task requires the UI to green its energy portfolio and achieve 40% renewable energy by 2020. Replacing coal with biomass is a central strategy. A variety of biomass fuel sources are being investigated including wood chips, micanthus grass, timber stand, and organic industrial byproducts.

A brief description of cogeneration technologies deployed:
The University of Iowa has operated a combined heat and power plant since 1926. The power plant is a combined heat and power plant facility that generates about one-third of the University’s electric power needs. Fuels burned at the Power Plant include coal, natural gas, and oat hulls (energy produced from oat hulls is captured in Options 1 and 2). The plant co-generates about 30 percent of the total electric power needs and produces all the steam energy used throughout the campus and hospital facilities. Steam produced by the plant is used for heating, production of chilled water for air conditioning, cooking, sterilizing, humidifying, and energizing other research and process equipment.
