Smartcity : A Feedback System for Energy Consumption and Costs

Many countries encourage large-scale deployment of smart meter infrastructure, allowing utilities to obtain near real-time information about the state of the grid infrastructure. This brings the potential to create feedback loops between generation and consumption [1]. Several studies showed that providing information about current consumption can positively influence consumption practices. Recent advances in energy disaggregation [2–4] allow to break down a households aggregated electricity consumption into individual appliances with an overall accuracy of about 90 percent [5]. Goal of this research is to develop an energy consumption feedback system that also provides information about energy costs. As tariffs become more dynamic and complex (e.g. time- or load-varying) storing them in redundant ways within energy feedback systems becomes more complicated. Therefore this information needs to be accessed from the utilities billing system
