Pilot Sites

Greece

Kimmeria student campus


The pilot site is located in a rural area about one kilometer west of the city of Xanthi, in North Greece. It includes a building complex of 11 buildings with a total area of 15.000 m2, consisting of eight buildings for student residences, one electromechanical equipment building, one restaurant and one amphitheatre, owned by Democritus University of Thrace (DUTH). Student residences are provided free of charge, therefore characterising the buildings as social housing.

Reliability and low operational costs through the maximum utilisation of RES technologies are the focus points of this demonstration site due to its social character. During the RENAISSANCE project, the demonstrator will run mainly using the local generation. The remaining share required is drawn by the main electricity. The successful execution of the pilot will unlock the potential replicability at large scale in university campuses and residences located in rural areas with similar climate conditions. High availability of renewable sources such as solar and heat would enable the creation of sustainable self-sufficient energy communities.

In order to engage end-users and eventually influence their consumption behaviour, smart meters will be installed and connected to the RENAISSANCE platform. Installation of smart meters for both thermal and electrical consumption will increase observability and transparency of consumption profiles by 100%, enabling to test demand-response schemes and innovative market models. Smart contracts and improved communication tools such as mobile apps will increase participation of end-users by 50%.

In addition, with the contribution of a simulation engine, the model will be extended to include its virtual connection with the macro-low-voltage/medium-voltage DSO level grid, by including energy production/consumption profiles of near-located energy intensive industries and that of the city of Xanthi, for which data are available. Through simulation results, the technical extent up to which a micro-grid can interact with a macro-grid can be identified (flexibility potential). Integrated solutions demonstrated in RENAISSANCE will be stress tested for their scalability and replicability.
