Pole replacement part of a greater plan to improve system reliability
CHICAGO,  Feb. 20, 2013  /PRNewswire/ -- ComEd announced that it completed the
replacement or reinforcement of more than 2700 wood poles in its service
territory in 2012, a 200 percent increase over previous years.  Inspecting,
replacing and reinforcing poles makes ComEd's electric system more storm
resistant and reduces customer power outages.  In addition to reinforcement and
replacement, ComEd inspected and treated more than 137,000 poles.

ComEd announced this goal early in 2012 as part of the grid modernization
program under the Energy Infrastructure Modernization Act (EIMA), which was
passed in 2011 by the Illinois General Assembly.  

"Utility poles are the foundation for our above-ground system," said  Terence
Donnelly, executive vice president and chief operating officer, ComEd.  "This
work is critically important in strengthening the electric grid. We are
improving the reliability of our electric system for our customers, which
includes preparing for damaging storms."  

ComEd uses treated wood poles for its distribution system.  Distribution poles
are typically up to 70 feet tall.   

ComEd is investing  $2.6 billion  to upgrade and improve the reliability of its
system as part of EIMA. The utility has been working to improve its
infrastructure and add smart technologies, bringing benefits to customers
throughout northern Illinois.  Major accomplishments in 2012 include:

* Installing over 470 distribution automation devices, or "smart switches,"
which avoided 82,000 customer interruptions last year   
* Replacing or treating more than 464 miles of underground residential cable -a
100 percent increase over previous years   
* Replacing over 46 miles of mainline cable- around four times the annual
* Assessing over 8,000 manholes and refurbishing more than 4,500.
