This means that the operation of the measuring point as well as the measurement can in principle be taken over by third parties, provided that the correct operation of the measuring devices in accordance with the calibration regulations is guaranteed by them. In order to structure the legal relationship between the network operator and the metering point operator, it is necessary to conclude a metering point framework agreement or a measurement framework agreement and to comply with the minimum technical requirements (TMA) for metering equipment in the electricity network and gas supply network. Mainova Servicedienste GmbH concludes the aforementioned contracts and minimum technical requirements for and on behalf of NRM in the NRM network area (Frankfurt am Main and surrounding areas, Main-Spessart).
