Wisconsin Paper Mills Cut Costs with Energy Efficiency, Hydropower
April 20, 2005
Stora Enso, a papermaking company with six paper mills in Wisconsin,
has proved that significant energy savings are possible in the paper
industry. Since 2001, Stora Enso has lowered its annual energy use at
the six mills by 22 million kilowatt-hours and 3.6 million therms of
natural gas, saving $3.5 million each year on energy. Wisconsin's
Focus on Energy, the statewide energy efficiency and renewable energy
program, worked with the company to employ such technologies as a
dryer management system, which automatically adjusts the operating
conditions of the paper dryers to maximize their efficiency. Focus on
Energy also helped the company refurbish two old hydroelectric
generators at one of its mills. See the Focus on Energy press release (PDF 113 KB). Download Acrobat Reader.
DOE considers papermaking to be part of the forest products industry,
which is one of eight industries that are focused on by the Industries
of the Future partnerships, part of DOE's Industrial Technologies Program.
A recent review of the program by the National Research Council
concluded that it is a well-managed and effective program, which
leverages its resources through a large and growing number of
partnerships. See the
Industrial Technologies Program Web site and the National
Research Council report.
Industrial energy efficiency is also the subject of this summer's
conference sponsored by the American Council for an Energy Efficient
Economy (ACEEE). The 2005 ACEEE Summer Study on Energy Efficiency in
Industry starts on July 19th in West Point, New York. See the
ACEEE Web site.
