Mäkinen et al. provide an indispensable view of business model opportunities for electric vehicle (EV) prosumers in the future energy market. The digitalization of energy markets has started a transformation to smart grids where information flows bi-directionally end to end between energy production and consumption. The chapter explores how prosumers can create, deliver, and capture value with EVs in future energy systems. Focusing on prosumers’ digital business models (DBMs), the chapter illustrates the complex interdependencies between various activities and actors needed in the development of an energy system. In addition to demonstrating prosumers’ EV DBMs and the current state of readiness in value creation, delivery, and capture, Mäkinen et al. develop a balanced policy approach that is based on these DBM microfoundations.
