Packaging Corporation of America Announces Investment to Reduce Energy and Electricity Costs and Consumption

LAKE FOREST, Ill.--(Business Wire)--
Packaging Corporation of America (NYSE:PKG) announced today that its Board of
Directors has approved major capital projects at its Counce, Tennessee and
Valdosta, Georgia linerboard mills which will reduce fuel and electricity
purchases at these mills by 50% and 75%, respectively.

The investment will include a new recovery boiler, turbine generator, and paper
machine drying efficiency improvements at the Valdosta mill, and a rebuild and
upgrade of two existing recovery boilers plus a new turbine generator at the
Counce mill. The net capital invested is expected to be about $215 million,
after deducting about $80 million in maintenance capital that will be avoided on
equipment being replaced. Both the Counce and Valdosta projects are expected to
be completed by the end of 2011. The after tax return on these projects is
expected to be between 20-25% of total capital ($295 million), or 25-30% of net
capital ($215 million). The range of returns is primarily a function of current,
proposed and potential legislation regarding tax incentives and benefits related
to the production of green electricity and energy.

Commenting on the investment, Paul T. Stecko, Chairman and CEO, said "These
projects will significantly reduce our manufacturing costs as well as reduce the
potential impact of escalating fuel and electricity costs. Upon completion of
the projects, our Valdosta mill will burn only internally generated, wood waste
and black liquor in its boilers and will self-generate 100% of its electricity
requirements. Our Counce mill will lower its purchased electricity requirements
by over 60% and lower purchased fuel consumption by over 35%. We expect
essentially all capital required for these projects to come from cash received
from alternative fuel mix credits, and existing cash on-hand."
