The smart grid is an advanced metering infrastructure made up of “smart meters” capable of recording detailed and near-real time data on consumer electricity usage. That data would then be sent to utilities through a wireless communications network. In recent years, utilities have increased the pace of smart meter deployment—smart meters are expected to be on 65 million homes by 2015. A smart grid could deliver electricity more efficiently and would enable consumers to track and adjust their energy usage in real time through a home display. But these new capabilities also implicate new privacy concerns.
