The difference between common one hour, whole-home energy data and Pecan Street’s high frequency, disaggregated data is dramatic. The first chart shows whole-home, one-hour energy data between 5 pm and midnight – the kind of data readily available from advanced electric meters. The second chart shows energy use in a home in Pecan Street’s research network. Data was collected every minute from multiple circuits in the home, giving an incredible minute-by-minute understanding of when — and how — electricity was used.
