1.3.2 End Equipment

As industries transition to clean, net-zero electricity systems, governments are taking important steps towards creating smart and flexible electricity systems, by helping unlock the potential for consumers to benefit from using smart technology to shift when electricity is used. The decisions help make sure consumers can use a wider range of services and devices in homes and small businesses to manage electricity consumption and reduce bills. For example, HVAC system heat pumps can be used or heated during the times when electricity is cheapest. An electricity meter can be used here for the following benefits:

  • Use electricity meter to calculate the power consumption of the end equipment, show the data to the consumer, thus allowing the consumer to know the basic power information of the end equipment.
  • Electricity meter with real-time clock (RTC) function: automatically heat or charge the end equipment when electricity is cheapest
  • Electricity meter is also a power monitor, to inform the consumer if the end equipment is working normally
