This includes an update to the Smart Metering Equipment Technical Specifications (SMETS) 1 Transition and Migration Approach Document (TMAD) to reduce the timeline for submission of Daily Migration Demand values to two weeks and to drive efficiencies in the migration forecasts and in the demand allocation process.
