Each point of entry and exit onto a Distribution System Operator's Distribution System has an associated Metering Point and each Metering Point has an associated Administration Number (MPAN) and Metering System Identifier (MSID).
MPAN is the term favoured in the SVA market and is used in the Master Registration Agreement (MRA), the governance document for the registration of Supplier Volume Allocation (SVA) Metering Points registered in Supplier Meter Registration Systems (SMRS).
MSID is the term favoured in the CVA market and is used by the Central Data Collection Agent (CDCA) and Central Registration Agent (CRA).
