Electricity Supplier Jargon

Accumulation meter – Also known as a basic meter. A device with which records the accumulated quantity of the electricity used at a property

General supply – General Supply register on your meter records how much energy you are using for your main supply. All meters will have this register. General supply is also referred to as ‘Light and Power’.

Controlled load- how much energy you are using for specific circuits that are wired into your meter (for example, electric hot water systems)

Generation – means the amount of electricity you are generating and providing to the electricity grid.

Maximum demand – greatest amount of electricity used for any day within the period (30 minutes or 15 minutes). Maximum Demand is calculated by identifying the highest half hourly interval usage that occurs during each “To Date” period and multiplied by two to obtain the maximum demand expressed in kW. For 15 minute intervals, the highest 15 minute interval usage that occurs during each “To Date” period is identified and multiplied by four to obtain the maximum demand expressed in kW.

Energy flow – what the energy has been used for

Home area network (HAN) – A home area network (HAN) is a network that operates within a small boundary, typically a house or small office. It enables the connection of various digital devices to share information over the same network. These digital devices may include In-home displays (IHD), Smart Thermostats, Computers and ‘Smart’ appliances (such as refrigerator or dishwasher).
A home area network can be used to monitor your near real-time and historical energy consumption patterns from your property so that you can determine ways to reduce your electricity use.

Interval meter – Also known as a smart meter. A meter which measures consumption of electricity for each specified interval. Intervals are usually every 30 minutes but can also be every 15 minutes. Can be manually read, but is generally remotely read using a communications network. Electricity distributors install interval meters at customers premises and collect the usage information.

Kilowatt (kW)- One kW=1000 watts.

Kilowatt hour (KWh) – The standard unit of electrical energy that represents the consumption of one kilowatt over the period of one hour.  A heater consuming 1 kw operating for one hour uses one kilowatt hour of energy. A television consuming 100 watts operating for 10 hours continuously uses one kilowatt hour.

National Metering Identifier (NMI) is a unique number which identifies the electricity supply point at your property. Your NMI can be found on your account from your electricity provider.

UOM – Unit of measure. kWh (energy), kW (demand).

Usage – consumption of electrical energy

Watt (W) – A measure of power present when a current of 1 amp flows under the pressure of one volt. 1 watt represents the expenditure of one joule of energy per second.
