EnergyMeasurementType Objects should support Interfaces for standardized energy data profiles, so called EnergyProfiles. The supported measurement values demanded by an energy data profile are specified by Interfaces applied to instances of the EnergyMeasurementType.
Table 21 shows the definitions of the Interfaces for the standardized energy data profiles. The EnergyProfiles represent standard Energy Measurement use cases and are therefore the preferred way to represent Energy Measurement data. It is recommended to support at least one of the EnergyProfiles.
