A declared level of kVA (kilovolt-ampere) is agreed before a supply is installed. This is in effect the maximum demand allowable under the agreement and is charged monthly whether the level of demand is reached or not. If it is exceeded it is charged for additionally and the level may then be increased to the peak maximum demand level for the following 12 months. The level of kVA declared is also guaranteed to be available to the site by the supplier.
A system employed by energy suppliers to charge customers for energy consumption.
CCL is a government tax on business energy consumption to encourage a reduction in gas emissions and greater energy efficiency. Taxable commodities are:
– coal and lignite
– petroleum and hydrocarbon gas in a liquid state
– coke, and semi-coke of coal or lignite
– natural gas as supplied by a gas utility, and
– petroleum coke.
The levy is index-linked and is reviewed on 1st April each year.

Method of checking the accuracy of data
This applies to a type of meter that has the data collected by telephone line, GSM, SMS or GPRS
Indicates the amount the recorded consumption should be multiplied by. Generally meters record actual consumption and the constant is 1 – higher consuming sites may have meters with a constant of 10 (also known as x10 meters).
A meter that remains on site but is disconnected from the network by removal of the main fuse.
Half-Hourly meters record electricity consumption every half hour of every day and the data is collected by telephone line, GSM, SMS or GPRS.
The power consumed over a short period of time, usually 15 minutes. MD meters are installed for premises requiring in excess of a certain capacity dependent upon the regional electricity company. MD metering is currently being converted to recording half-hourly.
A meter exchange is carried out when a meter has reached a certain age or becomes faulty. Meters can also be upgraded or downgraded depending on the requirement of the customer. A program of installing AMR meters is in progress to reduce the need for manual meter readings.
A unique identification number for an energy meter.
A separate register is required to record consumption at different times of the day. For example, an Economy 7 meter has 2 registers: day and night. Registers are also included on some meters to record capacity and waste. The button on the front of a digital meter allows the reader to cycle through the various registers.
When a meter clocks round to zero from its maximum possible recording.
A sub meter can be connected to a main meter in order to record the consumption of a particular area of a premises or specific equipment. A master and sub meter arrangement is usually preferred in large office blocks in order to record the consumption of each unit and communal areas.
A sub meter can be connected to another sub meter, often to save cabling but also to sub divide a unit already supplied by a sub meter.
