The Solar4CE-Cities project will be represented by Öko-Institut and TU Wien at the IEWT conference, taking place in Vienna from February 25 to 28, 2025. Together, we will deliver a joint presentation on “Collective Prosumerism in the EU Policy Environment and Translated Into Practice.” Our contribution explores the EU’s legislative and policy framework surrounding collective prosumerism, showcasing different formats that urban solar power sharing systems may take on from a regulatory perspective. To fill those rather abstracts formats into life, we will also provide examples of initiatives already implemented across various European Member States, highlighting specific features that come into play in translating collective prosumerism into practice.You can visit the Öko-Institut website for the updated EU policy scoping as well.
