Example of a report according to the German Federal Network Agency
The Federal Network Agency supervises various requirements of the EEG . This includes the proper handling of the collection of the EEG apportionment (e.g. including for self-supply arrangements).
In order to establish a uniform understanding of the regulations on measurement and estimation, the Federal Network Agency has published the Guideline on measurement and estimation for EEG apportionment obligations . It serves as an orientation aid for the citizens and companies concerned in order to promote practical and uniform application practice and to reduce the existing legal uncertainties.
This guide uses specific examples to illustrate the implementation of the regulations. In the following, one of these examples is used and presented based on the GridVis energy recording report. A comparison then illustrates how the energy recording report implements the recommendations of the Federal Network Agency.
Application example: Combination of the voluntary subordination rule with quarter-hourly measurement
(Corresponds to example 27 in the Guide to measurement and estimation for EEG apportionment obligations of the Federal Network Agency: Example27.pdf )
Numerical example of the application of the voluntary subordination rule when using quarter-hourly meters (R) and work meters (A)
