     PECO RECEIVES INDUSTRY HONORS FOR INNOVATIVE SYSTEM REPAIR APPROACH

  First of its kind transmission system issue requires commitment to safety,
                           teamwork and innovation

PECO was recognized by the Southeastern Electric Exchange with its Industry
Excellence Award in the Transmission category at the organization’s conference
and trade show in Orlando, Florida this week. This award is given annually by
the Exchange to the project it deems “best of the best” among all entrants in
this category.

PECO was honored for its response to an emergent repair to an underground 220
kilovolt transmission line located in North Philadelphia in March 2012. The
first of its kind in the more than 120-year history of the company, the
complex repair required support from more than eight different PECO
departments, local contractors, and employees from the company’s sister
utility ComEd, in Chicago. PECO sister company, BGE in Baltimore, Md., also
received S.E.E. awards in the Safety and Rates and Regulations categories.

“I’m extremely proud of the team of employees and contractors who came
together to collaboratively work to make this repair and ensure continued
reliable service for our customers,” said Eric Helt, PECO vice president of
Electric Operations. “The infrastructure that provides electric service to
tens of millions of customers throughout the United States is incredibly
complex, and complex issues sometimes require innovative solutions. This was
one of those instances.”

After returning the transmission line to service following a scheduled outage,
an issue occurred along a two-mile stretch of the underground portion of the
cable, leaving several large multi-service customers with one single service.
PECO crews utilized a special listening device to identify the location of the
damage, used innovative techniques to safely expose the damaged portion of the
cable, and coordinated the installation of a new section of cable – a complex
task that took nearly two weeks to complete.

The Southeastern Electric Exchange Industry Excellence Awards are given
annually in 11 different categories from substation, environmental, and
production, to distribution. Award submissions are reviewed by an industry
panel and are evaluated for achievement, innovation, improvement,
requirements, and technical complexity.

PECO has received numerous industry honors recently including; the Emergency
Recovery Award from the Edison Electric Institute in 2011 and 2012, the ENERGY
STAR® Partner of the Year Award in 2012 and 2013, and the 2012 American Gas
Association Safety Achievement Award. The company is consistently recognized
within the industry for its top decile safety performance and top quartile
reliability for electric and natural gas service. The company also is
frequently honored for its commitment to diversity and inclusion and community
impact.
