Biomass
and Power Generation
Significant opportunities exist for new generating capacity
even in fully developed regions. The United States, for
example, faces demand growth for electric power of about
1.3 percent a year on a base of 787 billion kWh consumed
in 2006. New generating facilities must meet stringent
environmental regulations. At the same time, retail electricity
providers continue to seek opportunities for diversifying
their fuel portfolios.
Our PowerMinn business near Benson, Minnesota, demonstrates
an innovative approach to power generation that reaps
environmental benefits as well as portfolio objectives.
First Turkey-Litter-Fueled Power Plant in the
United States
Minnesota is the largest turkey producer in the United
States. Every year, the state’s turkey growers need to
dispose of more than 2 million tons of poultry litter,
but lack a large-scale process to accomplish this. In
the past, heaps of turkey litter caused phosphate run-off
into surface water, and led to large algae build-ups
in Minnesota’s lakes.
Developed by Fibrowatt, a world class expert in poultry
waste development plants, our power facility generates
55 megawatts of net electric output via a steam-driven
turbine generator with steam generated by a conventional
single drum boiler burning 700,000 tons of turkey litter
annually. In addition, the facility sells its ash residue
as high-quality fertilizer.
Everybody Wins
Our project represents a “win-win” solution. Poultry
farmers achieve cost-effective litter disposal; a power
generation plant obtains inexpensive fuel; and a retail
power company achieve portfolio diversity at a reasonable
cost. The environment, too, comes out ahead.
Our plant initiated operations in September 2007, and
its success points the way for additional projects of
this kind in countries where environmental concerns play
a significant role in new generating capacity. We are
currently developing similar plants in Brazil and Ukraine.
