The N5GEH project

To implement the energy transition and the associated transition from a centralised to a decentralised energy system, a targeted 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. In particular, the National 5G Energy Hub addresses the application of modern communication technologies for the integration of sensors and actuators for the provision of energy-related services.

For this purpose, a basic software structure was developed in the first project phase (2018 – 2020), which includes the essential elements of data acquisition, data transmission, data storage and data visualisation. With regard to data acquisition and organisation, a scaling solution was implemented. Further information on this can be found in the summary of the final report.

The N5GEH open source software is structured in such a way that a kind of “modular system” is available for use, so that different application-specific solutions can be integrated.

The N5GEH offers satellite projects the provision of a platform for energy systems that can be adapted and used by research institutions and industrial companies for their services. The platform has a uniform data format and is created in a modular way, following the most modern development principles, which ensures that as many use cases as possible can be covered. Significant features continue to be:

Interfaces to common field systems and integration of commercially available gateways for further systems
Uniform user management and authentication
Prefabricated basic structures for energy services (monitoring / control / sector coupling)

For the implementation of the specific use cases of the satellite projects, they will be supported by the N5GEH by providing a freely available reference implementation. This will exemplify the integration of energy systems into a central platform and the use of basic services.

The N5GEH Focus Event

On May 7, 2026, a focus meeting took place at the Einstein Center Digital Future in Berlin, organized in cooperation with the accompanying research project “Energiewendebauen.” As part of the focus meeting, the cloud platform, along with use cases, results, and findings from the satellite projects, were presented and discussed to mark the official conclusion of the project. The official presentation was followed by a workshop that demonstrated a complete workflow using the N5GEH platform. Interactive exercises served to reinforce theoretical fundamentals and allowed participants to familiarize themselves with key functionalities within a specific use case. Overall, the meeting demonstrated that the N5GEH platform can address a wide range of technical applications. Although there are highly specific requirements and use cases at both the industry and project levels, the fundamental data processing workflows are comparable, and the FIWARE core components can be used across multiple projects to implement these use cases. There is a high degree of overlap between the projects with regard to data models. A particularly intensive exchange took place between the projects in this area, and industry-specific reference implementations were developed. Furthermore, a number of key challenges and development paths for digitalization projects in energy technology were identified.

Joint Summary Report

During the focus meeting, a joint summary report was presented, which, in addition to a project summary, provides an overview of the use cases, technical implementation, and main results of the individual satellite projects. The summary report is available:
