ComEd carried out the upgrades at the Wallace substation and transformed it into a smart substation as part of 2011 Smart Grid Law. It is the first of the 10 smart substations.
The company used modern technology to upgrade the substation and reduce the power outage frequency and duration.
The new technology installed on the Wallace substation will help ComEd to better monitor the electrical system and quickly respond to any problem.
Wallace smart substation is installed with sensors that prevent power outages by analyzing up to 1,500 pieces of information every two seconds and can alert ComEd system operators about the issues to happen.
ComEd executive vice president and chief operating officer Terry Donnelly said the company is investing in electrical system because of the Smart Grid law.
"Our approach addresses the complete substation. We upgrade all the electro-mechanical devices to microprocessor technology and install advanced equipment diagnostics," Donnelly added.
"This will dramatically improve our ability to constantly monitor the system, identify potential issues and keep them from becoming problems."
As a result of the Smart Grid law, ComEd is investing $2.6bn over 10 years to improve its infrastructure and add smart technologies, bringing benefits to customers throughout northern Illinois, US.
