Approved Service Description
This tScheme approval covers a PKI scheme operated by Smart DCC Ltd (and its subcontractors). The scheme is known as the 'Final Operating Capability SMETS1 Service Provider CA Service (FOC S1SP PKI)'. It enables Smart DCC to identify, and communicate securely with, smart meters installed in the early stages of the smart metering programme, which (in the absence of national infrastructure) could only communicate with the energy supplier that installed them. The new capability will allow consumers - whose homes were equipped with one of these early meters - to switch to a different energy supplier and still retain full smart metering functionality, including automatic reporting of meter readings.
In technical terms, the new PKI facilitates the regular exchange of information between a Head End System, operated by Smart DCC, and the Comms Hub which serves as the entry point for the smart meter installation in each home. A Home Area Network links the Comms Hub to the meters. The FOC PKI makes use of mature technical standards.
