PECO Completes New $22 Million Southwark Substation to Boost Energy Supply, Improve Electric Reliability for South Philadelphia

One of PECO's 80 Projects to Ensure "Summer Readiness"
PHILADELPHIA--(Business Wire)--
PECO has energized the first of five new distribution circuits
from its new $22 million electric distribution substation that will
meet the needs of the former Navy Yard and serve parts of South
Philadelphia.

The Southwark substation was completed after nearly three years of
planning, engineering design and construction. The facility will
relieve electric load on other substations in the area and ensure
reliability for the growing electric demand in the southeastern
quadrant of the city. It takes 69-kilvolt (kv) electricity from the
electric transmission system and converts the energy into lower
voltage for local distribution to homes, businesses and other
customers in the area.

PECO said Southwark is the third of four new electric substations
under development to modernize the electric infrastructure and meet
increasing demand in certain sections of the city. The company built
the Tuna substation along North Delaware Avenue in 2005 and completed
the Waverly substation in Center City in the spring of 2007. The
fourth major investment will boost electric supply for the University
City and West Philadelphia area, planned for completion in 2009. These
projects alone represent a $120 million investment in the Philadelphia
electric distribution system. Substations are hubs for local power
supply, tapping into high-voltage transmission lines on the regional
grid and delivering electricity on local distribution circuits.

"This project will benefit thousands of PECO customers with
reliable electric service this summer and for years to come. It was a
high priority for the company during the past two years," said Craig
Adams, PECO senior vice president and chief operating officer.

PECO is working on roughly 80 projects across the region as part
of its summer readiness program. These projects will expand capacity
and relieve electric load on existing equipment in certain areas
experiencing growth, deploy distribution automation and other new
technology, and improve performance on the company's 2,300
distribution circuits that deliver power to 1.6 million customers in
southeastern Pennsylvania. The capacity expansion projects represent
about one-third of PECO's $394 million capital investments for this
year. Other aspects of the summer readiness program include
wide-ranging system maintenance, circuit patrols, and emergency
planning.

Based in Philadelphia, PECO is an electric and natural gas utility
subsidiary of Exelon Corporation (NYSE:EXC). PECO serves 1.6 million
electric and 480,000 natural gas customers in southeastern
Pennsylvania and employs about 2,500 people in the region.
