Accenture Selected to Design Smart Meter System Infrastructure
for ComEd Pilot Program

Data management infrastructure will enable more responsive
and efficient customer service

CHICAGO, Sept. 21, 2009 ComEd, a unit of Exelon Corporation (NYSE: EXC), has chosen Accenture (NYSE: ACN) to design and deploy the data management system for its proposed Advanced Metering Infrastructure (AMI) pilot. The pilot, if approved by the Illinois Commerce Commission (ICC), will assess how advanced technology can improve service reliability, help customers make smarter decisions about energy use and contribute to lower energy costs and reduced carbon emissions.

Accenture will help ComEd integrate the smart meter infrastructure, including its data management system, with its existing information technology systems and business processes. Accenture will also collaborate with Itron, a leading provider of intelligent metering, data collection and utility software solutions, to integrate Itron`s Enterprise Edition Meter Data Management into ComEd`s existing suite of applications. By using a services-oriented architecture approach, Accenture will provide ComEd with a flexible infrastructure that allows the utility to respond more quickly and cost effectively to customer needs.

In its petition to the ICC, ComEd recommended that 141,000 smart meters be deployed in 11 suburban communities and the city of Chicago, as part of one of the most comprehensive tests of smart meters in the nation.

"The ability to read meters remotely and receive data more quickly with the smart meter system infrastructure will allow ComEd to increase operational efficiencies," said Fidel Marquez, senior vice president, Customer Operations, ComEd. "The information from the meters coupled with the new data management system means that we potentially can better utilize our field force, improve response to power outages and reduce costs."

Kyle Jordan, a senior executive in Accenture`s Utilities industry practice, said, "This smart meter pilot and new AMI infrastructure well-positions ComEd to take its operational performance to a higher level and to increase the level of customer satisfaction. More importantly, the pilot enables ComEd to align its grid and energy management strategies to Illinois` smart grid vision and plans."
