This report explains all demonstration activities conducted in Leipzig, Germany, as part of the SPARCS project. An overall summary of the Lighthouse demonstrations in Leipzig will be presented at the outset, followed by a summary of the details in the demonstration areas. The demonstration activities cover various low-carbon improvements in urban development,including buildings, energy systems and the use of e-mobility measures and citizen engagement initiatives.

The Lighthouse City Leipzig focuses on two physical districts (“Leipzig West”) and one virtual district. The virtual district consists of the virtual power plant, where a wide variety of assets are connected to create an optimised energy management system with real-time data. The platform (digital ecosystem) creates added value for Leipzig's energy system. The exchange of energy data with the various partners forms the basis for the development of the Virtual Energy Community.

In addition, various use cases were tested, such as the implementation of blockchain technologies, e-mobility concepts and a district heating study, etc. The solar thermal plant will be built in the Leipzig West district, which is part of the project. Finally, SPARCS also studies macro level demonstration actions in the city of Leipzig, for transforming the positive energy community. This step will focus mainly on the replication phase.

This report describes the implementation, the targeted outcome, schedule and partners’roles and responsibilities in the third year of the project.
