Informtion on energy meters and how to select the right electricity metering solution for your building.
Real Power is a measure of the actual power (Watts) dissipated by a load.
Hertz (Hz) is a measurement of the number of complete cycles per second of a waveform. Normal mains frequency is either 50 or 60 (Hz).
A Joule (J) is an energy measurement unit, determined as one Watt per second.
Current is the ‘volume’ of electricity flowing in a circuit and expressed as Amps.
The amount of energy your organisation uses and the charges for this are shown on your billing information from your energy supplier. The information may be estimated or taken from actual meter readings. We always recommended working from metered readings for accuracy.
Electricity suppliers in the UK can use different types of electricity meter dependent on your organisation’s total consumption and usage (domestic or commercial). The meter type will be shown on your electricity bill and will have a Meter Point Administration Number (MPAN) which will be a unique 13 digit number identifying the distributor and company providing the distribution network to the supply address.
Electricity suppliers in the UK can use different types of electricity meter dependent on your organisation’s total consumption and usage (domestic or commercial). The meter type will be shown on your electricity bill and will have a Meter Point Administration Number (MPAN). The MPAN is typically separated into two sections: the core and supplementary data. The core is a 13 digits and is a unique identifier with the supplementary data providing information about the characteristics of the supply and is the responsibility of the meter supplier. MPANs are also used by UK gas suppliers and the information can again be printed on the building operator’s billing information. MPAN’s may also be referred to as Supply Numbers or S-Numbers.
A Half Hourly (HH) Electricity Meter sends the latest energy usage meter readings to the energy supplier every half hour (30 minutes).
P272 is a regulation that rules that energy suppliers use detailed data (known as half-hourly HH consumption data) to calculate customer billings using advanced Automatic Meter Reading (AMR) meters. Installing P272 meters provides organisations and businesses with improved visibility of their energy consumption.
A Meter Operator (MOP) contract or agreement is a legal requirement for all half-hourly supplied electricity meters. The contract or agreement covers the supply of the electricity meter, its maintenance and the necessary telecommunications to send the recorded consumption data to your energy supplier or Data Collector (DC).
A Data Collector (DC) is responsible for reading your electricity and gas meters and processing the data including keeping records of the readings. A DC is also responsible for visual safety checks. In relation to this a Data Aggregator (DA) is responsible for collecting consumption information to meet the requirements of the P272 regulation for Balancing and Settlement.
Unit costs are the price rate per kilowatt hour (kWh) of energy (electricity or gas) supplied. Unit rates can vary for time of day (day or night rates) and the type of meter installed.
A Transmission Network Use of System (TNUoS) charge is a charge made to consumers to cover the cost of using the National Transmission System owned and operated by the National Grid to cover the cost of electricity delivery from power stations into an and across the transmission network in the UK.
