Which metering system records times of day energy consumption?

Which metering system records times of day energy consumption?

• A. Mastered Metered
• B. Sub-Metering
• C. Advance Sub-Metering
• D. Demand Metering

Answer: (C)

Time-based energy data comes from advanced sub-metering, which records energy usage in defined intervals and logs the exact times those usages occur. This interval data creates a time-stamped profile of consumption, letting you see how energy use varies by hour or day and support time-of-use rates or demand management. In contrast, a single building meter (master metering) shows only total building consumption, without per-unit timing details. Basic sub-metering can tell you how much a unit uses, but it often doesn’t provide the time-stamped data needed for daily or hourly patterns. Demand metering focuses on measuring peak power within intervals rather than building a full timeline of energy use throughout the day.
