MP162 SEC changes required to deliver MHHS

Ofgem’s Electricity Settlement Reform Significant Code Review (SCR) has concluded that settling all consumers on a half-hourly basis would bring net benefits of up to £4.5bn by 2045. Ofgem has therefore concluded that Suppliers should be mandated to settle their customers on a half-hourly basis. Delivering the full solution for market-wide half-hourly settlement (MHHS) will require Supplier Agents to be able to collect half-hourly meter reads from Electricity Smart Metering Equipment (ESME).

MP162 will introduce the changes needed to allow Supplier Agents to be able to collect half-hourly meter readings from ESME for MHHS. The solution will:
• Create a new User Role for non-Supplier Parties carrying out the Meter Data Retrieval (MDR) service
• Define the Service Requests the MDR User Role will have access to and the associated Target Response Times (TRTs)
• Define the User Entry Process requirements for the MDR User Role
• Define the associated security arrangements that will apply to the MDR User Role
