This paper presents the development process and a collectionof business concepts developed for renewable energy based smartdistrict energy systems, which are called in eHUB research project[1] as the Energy hub systems. According to the definition used inthe project [1] “An Energy hub is a physical cross point, similar toan energy station, in which energy and information streams arecoordinated, and where different forms of energy (heat, electricity,chemical, biological) are converted between each other or stored∗Corresponding author.E-mail addresses: mari.sepponen@vtt.fi (M.

It is a mechanism for optimised energy and informa-tion supply exchange that integrates via various energy networksits members (households, renewable energy plants, offices, andbusinesses). These members can be both energy consumers andproducers [1].
