CESEPS is an ERA-Net Smart Grids Plus project funded by the European Commission. The aim of the project is to support the development of smart energy products and services for local smart grids that better respond to the demands and concerns of all stakeholders in terms of performance, cost, reliability, safety and robustness, sustainability and energy-efficiency, and end-users’ comfort. The research in this project is focused on comparative validation of technologies and concepts of existing demonstrations and the further development of new innovative energy products and services for the present and medium-term using a co-evolutionary approach.
