The decentralisation of energy generation can provide multiple benefits. From passive consumers to active participants in the local energy system, this transition allows individuals and businesses to play a role in the energy system. The EU-funded eCREW project will coordinate the implementation of an innovative scheme of household cooperation in energy management. Specifically, it will develop community renewable energy webs allowing households to optimise energy efficiency and reduce expenditures. It will test the community webs on households, establishing some 200 webs with 15 000 participants. The system will be set up in such a way as to ensure that monetary benefits from the community renewable energy webs are distributed among the prosumers, traditional consumers and administrative entities.
