The system was introduced in 1998 in order to provide a competitive environment for the electricity companies; the system means that consumers are able to easily switch their supplier as well as administration being simplified.

Structure
An MPAN is commonly separated into two sections, the core and the supplementary data. The core is the final 13 digits and is the unique identifier. The supplementary data gives information about the characteristics of the supply. The supplementary data 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 the first.
Profile Class (PC)
The first two digits of a full MPAN reflect its profile class.

The MTC is represented by a three digit code that reflects the various registers a meter may have, whether it be a Single Rate, Day Night split, or even a Seasonal Time of Day.

Line Loss Factor Class (LLFC)
The Line Loss Factor class is used to calculate 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.

In addition to the Distribution Network Operators noted above who are licenced for a specific geographic area there are also Independent Distribution Network Operators (IDNO). IDNOs own and operate electricity distribution networks which will predominately be network extensions connected to the existing distribution network, e.g. to serve new housing developments.

Core
The MPAN core is the final 13 digits of the MPAN, and uniquely identifies an exit point. It consists of the 2 digit Distributor ID followed by 8 digits followed by 2 digits then a single check digit.
Check Digit
The final digit in the MPAN is the check digit validates the previous 12 (the core) using a modulus 11 test. The check digit is calculated thus:
- Multiply the first digit by 3
- Multiply the second digit by the next prime number (5)
- Repeat this for each digit (missing 11 out on the list of prime numbers for the purposes of this algorithm.)
- Add up all these products.
- The check digit is the sum modulo 11 modulo 10.
The algorithm in Java is:
int checkDigit(String toCheck) {
int[] primes = {3, 5, 7, 13, 17, 19, 23, 29, 31, 37, 41, 43};
int sum = 0;
for (int i = 0; i < primes.length; i++) {
sum += Character.getNumericValue(toCheck.charAt(i)) * primes[i];
}
return sum % 11 % 10;
}
In Pascal / Delphi:
function CheckDigit(MPANCore : array of Byte): Integer;
const
Primes : array [0..11] of Byte = (3, 5, 7, 13, 17, 19, 23, 29, 31, 37, 41, 43);
var
i : integer;
begin
Result := 0;
for i := 0 to 11 do
Result := Result + (MPANCore[i] * Primes[i]);
Result := Result mod 11 mod 10;
end;
In Ruby
- where mpan is a string
def check_digit(mpan)
primes = [3, 5, 7, 13, 17, 19, 23, 29, 31, 37, 41, 43]
(0..11).inject(0) { |sum, n| sum + (mpan[n, 1].to_i * primes[n]) } % 11 % 10
end
MPAN state
The supply identified by the MPAN can exist in one of three states: disconnected, de-energised, live.
- Disconnected: The service cable has been removed and the MPAN will not be reused.
- De-energised: The service cable is in place, but the fuse has been removed. The meter remains connected to the distribution network, but no electricity can be used.
- Live: Both the service cable and the fuse are in place. The supply is fully operational.
These terms are by no means standardised. For example, a disconnected supply might be referred to as a 'dead' supply.
Export MPANs
The vast majority of MPANs are used where energy is being consumed; Import MPANs are issued for this purpose. 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 is issued.
Microgeneration
Formerly, export MPANs required a half-hourly compliant meter to be installed. Since 2003, it has been possible for
microgenerationMicrogeneration is the generation of zero or low-carbon heat and power by individuals, small businesses and communities to meet their own needs.-Technologies and set-up:...
projects, with a capacity of 50 kVA or below and a non-half-hourly meter, to export back into the distribution network. The 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 is so small.
Metered Supply Point
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 the

Unmetered Supplies
It is possible for small predictable supplies to not be metered. Typical unmetered supplies are traffic lights, street lights, roadside telecoms cabinets, phone boxes, etc.
Such unmetered supplies are otherwise identical to all other supplies. It is the customer's responsibility to maintain an accurate and up-to-date inventory of unmetered supplies, and to inform the
