NRM Netzdienste Rhein-Main GmbH (hereinafter NRM) is a wholly-owned subsidiary of Mainova AG based in Frankfurt am Main. The company was established in 2005 to comply with the requirements of the Energy Industry Act to unbundle energy supply and energy networks, thereby ensuring non-discriminatory network access. The electricity supply network covers Frankfurt am Main, with the exception of some western districts, and is approximately 7,700 km long. As part of the implementation of §14a EnWG, transparency regarding the utilisation of low-voltage networks is becoming increasingly important. For reliable, grid-friendly control, it is necessary to capture and evaluate the current grid state reliably. For this purpose, NRM plans to introduce ONS measurement sensors, which enable continuous recording of relevant network parameters in the low-voltage range. The increasing penetration of low-voltage networks with controllable consumption devices is leading to new operational challenges. Existing measurement concepts do not provide sufficient data depth or transparency in many grid areas to detect grid bottlenecks early or to reliably assess control measures. Therefore, the use of standardised measurement sensors is planned, which can be installed in substations and other defined grid points to support operational and regulatory requirements.
