Interval Data

Interval meter data records electricity usage at regular time intervals, typically every fifteen or thirty minutes, providing a detailed view of how power demand changes throughout the day. Unlike monthly electricity bills, which aggregate usage into a single total, interval data reveals the exact moments when demand spikes occur. Because demand charges are based on these short measurement intervals, interval meter data is essential for understanding how commercial electricity costs are created. The articles in this section explain how interval meters record electricity usage and how interval data can be used to analyze peak demand events.
