CHICAGO, Aug. 29, 2013

CHICAGO, Aug. 29, 2013 /PRNewswire/ -- ComEd today announced that it has been
awarded LEED Silver green building certification for two facilities: the
recently refurbished space at Lincoln Centre Two in Oakbrook Terrace and the
company's newly built training center in Rockford. The LEED or Leadership in
Energy & Environmental Design rating system, developed by the U.S. Green
Building Council (USGBC), is the foremost program for design, construction and
operation of green buildings.

"ComEd is extremely proud to receive this environmental recognition from the
U.S. Green Building Council. This is the first time a ComEd facility has
earned LEED certification," said Anne Pramaggiore, ComEd president and CEO.
"Increasing the sustainability of our buildings is another way ComEd
demonstrates its commitment to the environment."

"ComEd's projects efficiently use natural resources and make an immediate,
positive impact on the environment, which will benefit future generations to
come," said Rick Fedrizzi, president, CEO & founding chair, USGBC.

In December 2012, ComEd completed a total renovation of floors two through six
of its Lincoln Centre Two facility in Oakbrook Terrace which included the
construction of a newly consolidated customer call center. The project
installed more efficient water fixtures as well as lighting fixtures and
installed ENERGY STAR^® qualified equipment and appliances. ComEd also
optimized the use of daylight to reduce the amount of energy expended on
lighting.

The USGBC awarded LEED certification to the Lincoln Centre Two facility for
its 100 percent purchase of green power, 100 percent use of ENERGY STAR^®
compliant power, 94 percent rate of recycling construction waste, 73 percent
use of regional materials, 40 percent reduction in lighting power density, and
other environmental practices.

In January, ComEd built its first training facility for employees, in
accordance with Smart Grid legislation. The Rockford Training Center is
comprised of 34,000 square feet of classroom and indoor training space, 85,000
square feet of outdoor training yards, a 100-seat auditorium and a customer
education area.

According to the USGBC, the training facility was awarded LEED certification
for its 100 percent maximization of open space, 81 percent management of
construction waste, 98 percent use of certified wood, 40 percent reduction in
water use, and other sustainability efforts.

Commonwealth Edison Company (ComEd) is a unit of Chicago-based Exelon
Corporation (NYSE: EXC), the nation's leading competitive energy provider,
with approximately 6.6 million customers. ComEd provides service to
approximately 3.8 million customers across northern Illinois, or 70 percent of
