eCREW coordinates and supports the roll-out of an innovative scheme of household cooperation in energy management. These are Community Renewable Energy Webs (CREWs), in which households jointly exploit household-level electricity generation and battery storage capacities and optimise energy efficiency and expenditures. The key purpose of CREWs is to support the transition of passive consumers to active participants in the local energy system through informed decisions and collective actions. In eCREW, three energy companies from DE, TR and ES (Lighthouse Communities) will roll-out the eCREW approach to their clients. A strong and divers Follower Community made up of entities from AT, DE, ES, FR, GR, SE and TR is made fit for giving the eCREW approach a “Go”, too. Together, 240,000 households will be enabled to join a CREW during the project runtime, establishing about 200 CREWs with 15,000 participants, saving at least 13 GWh/year. Cooperation within a CREW is facilitated through the provision of an award-winning smart phone app (PEAKapp), exploiting smart meter data to stimulate an increase in energy efficiency and the uptake of local renewable electricity generation. Administration of the CREWs, including the billing of consumption and generation, is covered by electricity retailing companies which are thereby transformed into holistic service providers; we call them Community Administering Entities (CAEs). In our approach, administrative burdens are relieved from the households, who are then free to focus their efforts on making the most out of their participation in a CREW. Monetary benefits from the eCREW approach are distributed amongst prosumers, traditional consumers, and the CAE through an innovative split-incentives contract applied in the project. The financial arrangement is tailored to ensure that the eCREW approach is financially viable and attractive for all participants and allows a non-discriminatory participation of all households.

PEAKapp targets the development of an unprecedented ICT-to- Human ecosystem to trigger lasting energy savings through behavioural change and continuous engagement, to enable increased consumption of clean and low-priced electricity from the spot market for household customers, to connect them to social networks, to motivate them through serious gaming, and to boost the efficacy of Smart Home building energy management systems by integrating their functionalities into the PEAKapp solution. With this first close-to-market-ready attempt to provide households with a dynamic electricity tariff in the EU, the door is opened for the most significant impact on the household electricity market since its liberalisation. The ICT ecosystem will be designed to require smart meters as only hardware with respect to in-house equipment, such that the system can be implemented almost immediately, given the EU targets for smart meter roll-out. These low hardware requirements allow for a fast market uptake, and thus a noticeable impact on EU energy consumption can be experienced with almost no delay and without the need of having to equip the 230mio dwellings in the EU with any extra efficiency hardware. Validation of the ICT ecosystem under real life conditions in the publicly owned social housing sector will be carried out in Austria, Estonia, Sweden and Latvia, and analyses of the collected data will allow for ground-breaking insights into consumer behaviour, while outstanding EU energy market analyses will derive implications for regulatory practice to better support energy efficiency goals. An outstanding market uptake strategy makes >3 electricity utilities ready-to-sign the implementation of the ICT-system, advises the European social housing sector about its benefits, and fosters European and international market uptake by distinguished exploitation activities, where the leading US stakeholder EPRI takes responsibility without funding.
