DR 1072 – Updated Codes for 210 and 300 Series Market Messages

Currently where an entire day’s readings are missing for Interval MPRNs for a D+4 data aggregation run the Data Aggregation system (OULPS)
generates estimates (kWh only) for use in settlement and also sends this data to Suppliers through Market Message 341. For the Enduring

only). Further Harmonisation.
