The village of Oak Park, a suburb west of Chicago, was recently selected from a list of competing volunteer neighborhoods to be the test site for smart grid technology.The project is a joint venture between the Korean Smart Grid Institute and the Institute for Sustainable Energy Development, and will involve placing a set of twelve or thirteen 3-kilowatt solar panels, along with a battery system, on the roofs of 100 residential and 100 multifamily buildings. They’ll also all be linked up to an electrical grid boasting smart meters, and once the test run of the system is over the building owners will get to keep the installations, worth $20,000
