LIFE-BECKON stimulates and boosts the deployment of Energy Communities across Europe by developing and delivering comprehensive support mechanisms for public authorities, promoters and Local Action Groups to better equip them to facilitate the creation of Energy Communities, therefore answering to clear needs and known barriers. The comprehensive support mechanism includes Technical Assistance cookbook to enable the creation of Technical Assistance Offices, Capacity Building program via Train the Trainer approach to increase stakeholder knowledge and integrated services via One-Stop-Shop platform to facilitate access to information, tools and guides as well as matchmaking among actors along the value chain. The support mechanisms will be validated in 3 supramunicipal areas in Avila-ES, Sofia-BG and Copenhagen-DK covering a wide range of conditions, cultural aspects and market maturities. Tailored dissemination and replication leverages the commitment of more than 30 authorities to replicate the mechanism and best practises, to reach a great number of stakeholders (>800), participation of more than 2500 citizens in energy communities and upskill 1400 actors during the 3 year duration of the project.
