What is an electricity sub-meter?
An electricity subsidiary meter (sub-meter) is a meter that allows for the monitoring of electricity usage on a portion of your private installation past the revenue meter. Typical users of sub-metering are residential properties with a granny flat, apartment buildings, shopping centres, mobile home parks and commercial buildings.
The revenue meter records the total consumption and the electric sub-meter records the part consumption for the sub-metered area only. Thus, the sub-meter’s consumption is recorded in the revenue meter.
