38-517: For half-hourly metered supplies, the half-hourly data collector (HHDC) retrieves the energy consumption data from the meter and makes any necessary estimates. The half-hourly (HH) data is a history of the customer's electricity consumption for each half-hour period. For non-half-hourly metered supplies, the Non-Half-Hourly Data Collector (NHHDC) determines the consumption by calculating the advance (the difference between

76-523: A meter serial number . Although it is common for an MPAN to be associated with one meter serial number, in some cases there is a many-to-many relationship. For example, one meter could be associated with both an import and an export MPAN, or one MPAN could be measured by three separate meters. It is possible for small predictable supplies to be unmetered. Examples are street lights, traffic signals, signs, bollards, telephone kiosks, CCTV and advertising displays. For an item of equipment to be connected to

114-452: A half-hourly basis. The Metered Supply Point (MSP) is the point at which the meter measuring a customer's consumption is located. It is thus also the point at which either the distribution network operator 's supply, or the building network operator's lateral cable, terminates and the customer's equipment begins. In order to firmly establish a supply's MSP, the MPAN needs to be associated with

152-507: A half-hourly compliant meter to be installed. Since 2003, it has been possible for microgeneration projects, with a capacity of 30 kW or below, to have a non-half-hourly meter to measure export back into the distribution network. Uptake was slow, with the first microgeneration export MPAN being issued in June 2005. Some suppliers may not bother to register the export MPAN in MPAS as the revenue

190-445: A meter administrator who will use daily data from a photo-electric control unit (PECU) array which is then used to calculate the energy consumption. A PECU array is a device that holds a representative number of the photocells that authority uses on their street lights or traffic signals. By trading energy as unmetered half-hourly the authority will accurately pay for the energy consumed by their declared unmetered equipment, and because

228-613: A specific geographic area, there are also independent distribution network operators (IDNOs). These own and operate electricity distribution networks which are mostly network extensions connected to the existing distribution network, e.g. to serve new housing developments. Scottish Hydro Electric Power Distribution also provide distribution services in South Scotland as an IDNO and Southern Electric Power Distribution provide IDNO services in all other England and Wales areas. Other IDNOs have no "base" area. The supply identified by

266-549: Is a 21-digit reference used in Great Britain to uniquely identify electricity supply points such as individual domestic residences. The system was introduced in 1998 to aid creation of a competitive environment for the electricity companies, and allows consumers to switch their supplier easily as well as simplifying administration. Although the name suggests that an MPAN refers to a particular meter, an MPAN can have several meters associated with it, or indeed none where it

304-479: Is a 3 digit code that reflects the various registers a meter may have, such as a single rate, day/night split, or a seasonal time of day. The Line Loss Factor Class or LLFC is an alphanumeric code used to identify the related Distribution Use of System (DUoS) charges for the MPAN. The figure reflects both the amount of distribution infrastructure used to supply the exit point and the amount of energy lost through heating of cables, transformers, etc. The MPAN core

342-444: Is a website that allows users and authorised industry parties to search for supply details (past and present) using such things as the 13-digit MPAN bottom line number, the meter serial number or the postcode. The user can determine a wide range of data relating to the supply including the full address, meter details, the current energisation status and also the appointed parties (i.e. the supplier, distributor, MOP, DC and DA). The site

380-619: Is an unmetered supply. A supply receiving power from the network operator ( DNO ) has an import MPAN, while generation and microgeneration projects feeding back into the DNO network are given export MPANs. The equivalent for gas supplies is the Meter Point Reference Number and the water/wastewater equivalent for non-household customers is the Supply Point ID . An MPAN is commonly separated into two sections:

418-641: Is appointed. Unlike a DNO or an IDNO, BNOs may be exempted from any licensing requirement by schedules 2 and 3 of The Electricity (Class Exemptions from the Requirement for a Licence) Order 2001 and this allows those responsible for the building network (such as a housing association) to employ any suitable electrical contractor on an ad-hoc basis. In Canada, the distribution network operators are known as local distribution companies ( LDC ). LDCs normally buy their power from larger companies, sometimes ones dedicated solely to wholesale supply. They re-sell it to

456-551: Is known as balancing and settlement and is regulated according to the Balancing and Settlement Code (BSC). A data collection charge is a fee paid to the data collector for determining the energy consumption of the supply. The charge may be shown separately on an electricity bill or it may be incorporated in the electricity supplier's overall charges. Meter Point Administration Number A Meter Point Administration Number , also known as MPAN , Supply Number or S-Number ,

494-476: Is populated from information sent from the supplier regarding the metering system. Only non-domestic users (with two valid MPANs that are not Profile Class 1 or 2) can register to access this service. The final digit in the MPAN is the check digit, and validates the previous 12 (the core) using a modulus 11 test. The check digit is calculated thus: In Matlab: In Pascal / Delphi: In Ruby: In Visual Basic: In VisualBasic.Net 2010: Or VB.Net 2010, avoiding

532-678: Is so small. Following the closure of the feed-in tariffs , in January 2020 Ofgem introduced the Smart Export Guarantee (SEG) arrangements, where an export MPAN is allocated to allow a supplier to pay a customer for export of low-carbon energy. Export capacity over 30 kW is required to be half-hourly metered. As part of the Marketwide Half Hourly Arrangements (MHHS), all export consumption will be required to be registered and settled on

570-463: Is the customer's responsibility to maintain an accurate and up-to-date inventory of unmetered supplies, and to inform the UMSO (UnMetered Supplies Operator) of all changes to the connected equipment within one month of the change. Larger local authorities generally have unmetered supplies with a demand over 100kW and are required to trade their unmetered energy on a half-hourly basis. To do so, they employ

608-420: Is the final 13 digits of the MPAN, and uniquely identifies an exit point. It consists of a two-digit Distributor ID, followed by an eight-digit unique identifier, then by two digits and a single check digit. Great Britain is divided into fourteen distribution areas. For each area a single company, the distribution network operator , has a licence to distribute electricity. They effectively carry electricity from

646-498: The Energy Networks Association . As of October 2022 , six company groups hold the fourteen distribution licences: In addition to the distribution network operators noted above who are licensed for a specific geographic area there are also independent distribution network operators (IDNO). IDNOs own and operate electricity distribution networks which will predominantly be network extensions connected to

684-497: The National Grid to the exit points (each having a unique MPAN and a possibility of several meters) where the customers are. The owner of the distribution network charges electricity suppliers for carrying the electricity in their network. Their DNO licensed regions are the same geographic areas as the former nationalised electricity boards . In addition to the distribution network operators noted above who are licensed for

722-536: The Office of Gas and Electricity Markets . There are fourteen licensed geographically defined areas, based on the former area electricity board boundaries, where the distribution network operator distributes electricity from the transmission grid to homes and businesses. Under the Utilities Act 2000 they are prevented from supplying electricity; this is done by a separate electricity supply company, chosen by

760-425: The transmission system operator (responsible for transporting power in bulk around the country). In France , Enedis , a subsidiary of EDF , distributes approximately 95% of electricity, with the remaining 5% distributed by 160 local electricity and gas distribution companies ( entreprises locales de distribution d'électricité et de gaz or ELD). In Great Britain , distribution network operators are licensed by

798-494: The MPAN can be in one of four states: disconnected, de-energised, live, and new. These terms are by no means standardised. For example, a disconnected supply might be referred to as a 'dead' supply. The vast majority of MPANs are import MPANs, where energy is being consumed. However, if a supply exports to the distribution network, then an export MPAN is issued. If a supply both imports and exports, then both an import MPAN and export MPAN are issued. Formerly, export MPANs required

836-419: The average of the maximum monthly electrical demands in the three months of highest demand, either in: exceeds 100kW. HH data is recorded by the meter and collected by an onsite download, or by remote communication methods such as GSM , SMS , GPRS or telephone line. Domestic NHH import MPANs always have a profile class of 01 or 02. Domestic NHH export MPANs are allocated a profile class of 08. The MTC

874-491: The central online database of electricity supply points. Their trade association is the Energy Networks Association. In 1990, the area boards were replaced by regional electricity companies , which were then privatised. The distribution network operators are the successors to the distribution arms of the regional electricity companies. The distribution network operators have a trade association called

912-450: The consumer, who makes use of the distribution network. Distribution network operators are also responsible for allocating the core Meter Point Administration Number used to identify individual supply points in their respective areas, as well as operating and administering a Meter Point Administration System that manages the details relating to each supply point. These systems then populate ECOES (Electricity Central Online Enquiry Service),

950-406: The core and the top line data. The core is the final 13 digits and is the unique identifier. The top line data gives information about the characteristics of the supply and is the responsibility of the supplier. The full MPAN is required to be depicted on electricity bills (the boxes on the top and bottom line are generally unaligned). The core data is on the second line, the supplementary data on

988-551: The customer's appointed electricity supplier for billing, with an electronic copy of the EAC being sent to the appointed data collector. The DNO make a Distribution Use of System charge on the electricity supplier for the delivery of the electricity to the customer's unmetered equipment. Each non-half-hourly supply has a four digit code called the Standard Settlement Configuration (SSC), which specifies

1026-411: The data is downloaded daily the authority will see their energy invoices change throughout the year to represent the changes in the seasonal daily lighting levels. If, however, the unmetered supplies are being traded as non half-hourly the UMSO undertakes the responsibility to calculate an EAC (Estimated Annual Consumption). This is done using a simple formula which takes into account the circuit watts of

1064-422: The distribution network via an unmetered connection, its consumption should typically not exceed 500 watts and it should operate in a predictable manner, with no provision for it to be manually turned on/off at the end user's request. Generally the equipment would either be in operation and taking a supply of electricity 24 hours a day, or be controlled by a photocell, as is often the case for street lights. It

1102-538: The equipment and the annual hours of operation. For example, a piece of equipment that is in use 24 hours per day will have annual hours of 8766. For, say, a CCTV camera rated at 24 circuit watts the EAC would be 210.384kWh, calculated as circuit watts × annual hours divided by 1000. As a result of Ofgem's decision to progress with Marketwide Half Hourly Settlement (MHHS) all new unmetered supplies from April 2024 will be half hourly and existing non half-hourly unmetered supplies will move to half hourly trading during 2024. If

1140-409: The equipment is street lighting the same process is used for non half-hourly; however, the annual hours will change as each photocell is assigned a set number of annual hours which indicate how and when the lights turn on and off. These annual hours have been set by Elexon and are not locally agreed with the UMSO by the customer. Once an EAC calculation has taken place, an EAC Certificate is provided to

1178-425: The existing distribution network, e.g. to serve new housing developments. A further, smaller level of distribution is the building network operator (BNO), usually a company employed by the building owner, in a large building with many meters, such as a block of private flats. In this case, the DNO may act as BNO and its responsibility may include the sub-mains to the individual flats, or DNO responsibility may end at

1216-491: The first incomer, in which case the independent BNO is responsible for the secure distribution cabling 'laterals' between that point and the individual fuses and meters. Historically such cabling would have been maintained and sealed by electricity boards that preceded the DNOs, and different DNOs supplying buildings of different sizes and conditions, may choose to adopt the wiring in the building or to insist that an independent BNO

1254-417: The first. Only the last digit on the bottom row is the check digit. The first two digits of a full MPAN reflect its profile class. Profile class 00 supplies are half-hourly (HH) metered, i.e. they record electricity consumption for every half hour of every day, and supplies of the other profile classes are non-half-hourly (NHH) metered. A NHH supply must be upgraded to HH where: Any Metering System where

The NHHDC is also responsible determining the Estimated Annual Consumption (EAC), which is a forecast for a year ahead. The EAC is initially provided by the supplier, and thereafter forecast based on actual meter readings. Data from the Data Collector (EAC/ AA's) is provided to

1330-484: The non-half-hourly data aggregator, which aggregates the individual values provided into a single figure split in a number of ways e.g. geographically or by supplier. This aggregated data is then provided to the Central Systems, maintained by Elexon, to determine the value of energy which has been used by suppliers so that they are able to settle with the distribution network which generated the energy. The process

1368-404: The number of registers a meter has, and the times that each register is recording electricity usage. The times that a register is recording is specified with a five digit code Time Pattern Regime (TPR). So for example a supply with SSC 0943 has two registers with TPRs 00404 and 00405. The 00404 TPR register records from 01:00 to 02:30 and 08:00 to 23:30, and the 00405 register records for the rest of

1406-596: The time. Each DNO operates a Meter Point Administration System (MPAS) which holds the following information for each MPAN: MPRS is the name of the software package that implements the MPAS system for all DNOs. Since MPRS is used by most DNOs it is often used interchangeably with the term MPAS. ECOES (formally the Electricity Central Online Enquiry Service) is now the Electricity Enquiry Service (EES)
