What is Utility Interval Data?

Interval data from an electric utility consists of detailed measurements of energy use (kW, kWh, W, or Wh) taken at specific times, usually every 15, 30, or 60 minutes, using a smart meter. This data is typically provided to customers in Excel, CSV, or XML formats. Unlike monthly electric bills, which only show total energy consumption for the entire month, interval data offers a granular view of how energy is used throughout each day. However, not all sites have smart meters installed, and not all utilities offer interval data. Customers should contact their utility company to learn what data and tracking options are available to them.
