customers of Illinois. It was passed by the Illinois General Assembly against vehement and persistent opposition from the Attorney General, AARP and informed Illinois citizens. ComEd spent around $16 million convincing General Assembly to over-ride Governor Quinn's Veto. When elected, Governor Rauner signed another bill favoring ComEd over the rights of citizens to have a choice to opt out from installation of Wireless Smart Meter. ComEd and the other primary utility company in Illinois have together installed more than 3 million smart meters—digital devices that collect information about how much electricity is used—at customer homes and businesses. The meters send that information to ComEd through wireless technology. ComEd has said that the technology "has avoided 7.6 million outages and generated $1.4 billion in societal savings." On February 28, 2018, Illinois utility regulators authorized ComEd to establish a 10-year electric microgrid demonstration project on the South Side of Chicago. "The Bronzeville Community Microgrid Project will connect with a microgrid at the Illinois Institute of Technology, creating one of the first utility-scale microgrid clusters in the nation, ComEd officials said," according to Daily Energy Insider.
