ComEd Activates New Smart Substation on Chicago's South Side as Part of Grid
Wallace Substation is the first of 10 smart substations planned under the 2011
Smart Grid law
CHICAGO, March 27, 2013
CHICAGO, March 27, 2013 /PRNewswire/ -- ComEd announced today that it has
completed digital upgrades to a substation that will help improve reliability
for approximately 28,000 ComEd customers on the South Side of Chicago.
The Wallace "smart substation," located in the Auburn-Gresham neighborhood on
Chicago's South Side, uses state-of-the-art technology to reduce the frequency
and duration of power outages. It improves ComEd's ability to monitor the
electrical system and respond quickly to potential issues, rather than
reacting to problems after they occur. The Wallace smart substation is
equipped with sensors that can help prevent power outages by analyzing up to
1,500 pieces of information every two seconds and can alert ComEd system
operators when, or even before, problems arise.
"Because of the Smart Grid law, we are making the investments needed to create
a 21^st century electrical system," said Terry Donnelly, executive vice
president and chief operating officer, ComEd. "Our approach addresses the
complete substation. We upgrade all the electro-mechanical devices to
microprocessor technology and install advanced equipment diagnostics. This
will dramatically improve our ability to constantly monitor the system,
identify potential issues and keep them from becoming problems."
The Wallace facility is the first substation to be transformed into a smart
substation under the Smart Grid law enacted by the Illinois General Assembly
in 2011. ComEd will transform 10 substations into smart substations over the
next five years.
Features of the facility include:
oAn "Intelligent Substation Dashboard" that provides information on the
overall health of the substation components and communicates directly to
ComEd when something is wrong.
oDigital technology that makes it easier for ComEd to identify fault
locations so that crews can be sent more quickly and directly to problem
oTechnology that will help both customers and ComEd maximize the value of
smart meters. Smart substations receive voltage data from the meters,
which enables ComEd to better monitor, manage and respond to system
issues. This connectivity also allows ComEd to view historical trends
related to energy use and system performance, which will help the company
plan for and manage during periods of extreme heat.
As a result of the Smart Grid law, ComEd is investing $2.6 billion over 10
years to improve its infrastructure and add smart technologies, bringing
benefits to customers throughout northern Illinois. Major accomplishments in
oInstalling over 470 distribution automation devices, or "smart switches,"
which avoided 82,000 customer interruptions last year
oReplacing or treating more than 464 miles of underground residential cable
– a 100 percent increase over previous years
oReplacing over 46 miles of mainline cable – around four times the annual
oAssessing over 8,000 manholes and refurbishing more than 4,500
oReplacing or reinforcing more than 2,700 wood poles.
