MP094 Supporting prepayment customers in no SM WAN scenarios

Latest update SECAS will now develop a straw man solution with the Proposer before returning to the Working Group.

What is the issue?

The Proposer has raised concerns that the minimum functional requirements set out in the second major version of the Smart Metering Equipment Technical Specifications (SMETS2) do not result in a device that is sufficiently robust to serve smart prepayment customers effectively. Similarly, the Adoption and Enrolment of SMETS1 meters in the Data Communications Company (DCC) leads to the same loss of resilience in relation to SMETS1 meters.

The Proposer seeks a solution to be able to effectively manage SMETS2 prepayment customers in no Wide Area Network (WAN), intermittent WAN or DCC outage scenarios equivalent to the commercially developed solution available from the Secure SMETS1 product.
