The aim of the SERENE project is to develop and demonstrate sustainable, integrated, cost-effective and customer-centric solutions for local communities. The idea is to integrate different energy system carriers and new renewable generation units in the local communities based on their social and technical status today to meet their energy needs in the coming years. The users has to be involved in the changes of the energy system and be informed about different technical opportunities and business cases to make decisions about their participation. Depending on the actual site, the new energy system involve different storage technologies (battery energy storages, heat storages, water storage-systems), demand response systems to enhance the flexibility of the systems (activating for instance electric vehicle charging stations and heat demand supplies), electric transportation systems like electrical vehicles or buses, heating system improvements using heat-pumps and integration of new renewable generation sources mainly in form of photo voltaics. The SERENE project will establish demonstrations in local villages in three European countries - Denmark, The Netherlands and Poland. The experiences gained at the demonstration sites will be analyzed and evaluated for replicability in firstly Europe but also world wide. Technical benchmark models and solutions will be set up together with their business models, and it is evaluated how different legal aspects form the involved countries will affect the possibility for replication. Further, the needed user involvement and their interest to join are evaluated seen from both geographic, social, environmental and economic conditions and characteristics.
