In the future energy system with 100% renewable energies, it is essential to efficiently network the decentralised sector coupling of electricity, heat and electromobility at the neighbourhood level. This is particularly relevant for the utilisation and realisation of local grid-related flexibility potential for system stability, as well as for secure digital communication and the acceptance and continued application of concepts beyond pilot projects.

However, concrete (measurement) data and information from the utilisation phase of a neighbourhood are required as a basis for the evaluation of coherent concepts and plans. The innovative Helleheide real-world laboratory offers a unique opportunity to investigate what happens after the design, construction in the neighbourhood and initial commissioning, e.g. to what extent planned synergies are realised and to what extent the acceptance of the diverse stakeholders also plays a role in operation.

• Support for the supply concept until final completion
• Operational optimisation through intelligent regulation and control (Quartiers Energiemanagement – QEMS) of the integrated and sector-coupled energy supply system in the neighbourhood over several cold periods after initial occupancy
• Answering questions about operating modes and optimisations that may arise from future changes to the supply concept, including those resulting from multi-point feed-in of different heat generators into the local district heating network
• Direct marketing and dynamic tariffs
• Continuation and accompanying evaluation of the further participation of users, citizens and stakeholders, as well as the investigation of neighbourhood development
• Networking of stakeholders from the housing industry, research and energy cooperatives
• Preparation of neighbourhood and operating data for the “Energiewendebauen” research network and publication within the framework of the national research data infrastructure “NFDI4Energy” in order to facilitate the transfer of scientific results into business practice. “NFDI4Energy” is the national research data infrastructure for energy system research, which is funded by the BMBF and developed in coordination and exchange with actors from the “Energiewendebauen” research network.
• Further development of the guidelines based on practical experience, incorporating current regulatory changes and framework conditions
• Linking with municipal heat planning

The follow-up project to the Energy Neighbourhood focuses on monitoring the measurement technology installed in the neighbourhood. Energy traffic lights indicate when CO2-neutral electricity is available in the neighbourhood. Eye-2-Sky cameras enable meaningful PV forecasts to be made. The district's heating network also offers good data collection and testing facilities. Various sensors for temperature measurement have been installed, and the district's technology island has a direct connection to the heating network for testing different technologies. The PV systems used to calculate generation were installed by OLEGENO and are available to tenants as part of a tenant electricity concept.
