The N5GEH project

To implement the energy transition and the associated transition from a centralised to a decentralised energy system, an initiative is needed to introduce modern communication structures in the field of decentralised energy technology. The National 5G Energy Hub therefore aims to create digitisation and application routines to enable users to develop new technologies for the energy transition. The National 5G Energy Hub addresses in particular the application of modern communication technologies for the integration of sensors and actuators for the provision of energy technology services.

The scientists from the fields of telecommunication, mechanical and electrical engineering of TU Dresden and RWTH Aachen decided on 1 May 2018 to join their forces and expertise and embarked on the joint project “National 5G Energy Hub”. They worked together with selected industry partners for the last two years to apply 5G standard in the energy sector, especially in the field of energy supply to buildings.

In the first phase of the project, a basic software structure was developed that includes the essential elements of data acquisition, data transmission, data storage and data visualisation. With regard to data collection and organisation, a scaling solution in the form of a cloud platform was implemented.

The functionality of the platform was evaluated on the basis of four use cases that consider the building, the electrical network and an entire district. The functionality of 5G and other known radio-based technologies was mirrored in each use case.

Phase II of the project, which started on 01.01.2021, aims to further develop the existing software platform structurally and functionally. The existing use cases are to be continued and extension to include further use cases from satellite projects is targeted. Aspects of security and quality management of the software are important here.

Draft proposals for satellite projects can be submitted within the framework of the call for proposals “Communication technologies for the energy industry”. Information on this can be found at
