The successful deployment of the energy transition relies on the capability of market players to develop innovative business models to address emerging business opportunities associated with the diffusion of new energy efficient technologies (i.e. reduce kWh/m2) and renewable decentralized energy systems (i.e. reduce CO2/kWh). The challenge addressed in this project is to identify and develop attractive business models tailored to EEB&D and bridging other market segments that were previously well-separated and are now overlapping. The development of guidelines will focus on the new roles of stakeholders e.g. customers increasing autonomy and flexibility, emerging aggregators, and flexibility providers, as well as on the interactions with closely related sectors (e.g. mobility and storage).
