Smart Grid technologies embed new sensing, control, and communications technologies into utility networks and devices. The connected home is a convenient term to describe the burgeoning applications that can improve security and quality of life and reduce operating costs for people in a dwelling. Given the focus on the privacy risks related to energy usage data, most of our discussion will address Home energy management systems and the single- and multifamily residential market sectors, which have the most apparent privacy-related risks. Disaggregation technologies use specialized current-sensing equipment and data algorithms to break down electricity use into individual device or appliance consumption. These technologies can be deployed at the smart plug level or at the electrical panel as a “whole home” solution. Price-based systems are precursors to future transactive energy markets and are predicated on the assumption that electricity (or gas or water in the future) is in some sense dynamic in price.
