As part of the University of Iowa Research Park's efforts to promote renewable energy
use, the new campus power plant's engine generators are designed to operate primarily
on landfill gas when the pipeline from the Iowa City Landfill is completed, with natural
gas as a secondary fuel source. To make it more efficient, the plant's waste heat recovery
system captures waste heat from the gas engine generator's cooling and exhaust systems
to produce hot water for heating, or chilled water for cooling, campus facilities.

he new 2.8-MW Tri-Generation Power
Plant exemplifies the University of
Iowa Research Park's (UIRP) commitment
to sustainable energy and its green
initiative for the future of its campus and surrounding
community. The plant helps reduce
the campus's carbon footprint by reusing an
existing heating plant building; by its choice
of fuel sources and emission controls; and by
centralizing the cooling, heating, and electrical
service in one location. It also creates a
hands-on teaching environment for the university's
engineering school.
With its versatile design, the plant will
cut both carbon emissions and energy costs.
" Even at partial completion we are receiving
benefits. We can use the engine generators
to offset load limitations from Alliant
Energy. During testing phases at the new
University of Iowa Information Technology
www.powermag.com
Center, electrical demands often would have
exceeded Alliant's demand limit set for our
campus. The engine generators are turned
on to reduce the demand from the electric
company, saving [the campus] thousands of
dollars each time, " Steve Kottenstette, plant
manager told POWER in July.
Using landfill gas is similar to using anaerobic
digester gas, according to Tom Hickey,
PE, who works for Stanley Consultants
