POCITYF is a H2020 European project delivering Positive Energy Districts (PED) in mixed urban settings and heritage areas. It will combine Positive Energy Blocks (PEB) with grid flexibility, e-mobility, innovative ICT technologies and citizen engagement strategies. Activities will be carried out in two Lighthouse cities: Évora (Portugal) and Alkmaar (Netherlands). Six fellow cities will replicate the works: Granada (Spain), Bari (Italy), Celje (Slovenia), Ujpest (Hungary), Ioannina (Greece) and Hvidovre (Denmark). This project has received funding from the European Union Horizon 2020 research and innovation program under grant agreement No 864400.
