In this paper we present a framework that aims at exploring and explaining how an energyefficiency and flexibility ecosystem emerges. The framework builds on two theories, namelyinformation ecology theory and architectural theory of digital innovation. The framework isused in an initial test by using descriptive data from an organization working as an aggregatorin the energy market. From the combination of the theories and the initial test usingdescriptions from the aggregator case and its products and services in the context of energyefficiency and flexibility the potential of the framework is shown. It can be concluded thatthe framework has a potential to explore and explain the ecosystem of an aggregatorregarding energy efficiency and flexibility and by highlighting the four integration tasks;sharing, combining, standardizing, and multi-homing it can guide future development of aplatform ecosystem.
