The OneNet project, funded by the European Commission, was launched in October 2020 to address the challenges faced by transmission system operators, distribution system operators, and consumers due to the increasing decentralization of the electricity supply system.

This unprecedented challenge requires an unprecedented solution. Therefore, the two major associations of network operators in Europe, ENTSO-E and E.DSO, have mobilized their members to form a unique consortium.

Led by Fraunhofer FIT (coordinated by Prof. Antonello Monti) and the Fraunhofer Center for Digital Energy, the OneNet project aims to develop and demonstrate a European approach to the flexibility and decentralization of the electricity supply system. Many projects have addressed this topic in the past, but OneNet is unparalleled in scope and size, with a total budget of over 28 million euros (co-funded by the European Commission with approximately 22 million euros).

The key elements of the project include defining a common electricity market design for Europe, a common IT architecture and IT interfaces, and large-scale demonstrators to implement and showcase the scalable solutions developed throughout the project. These demonstrators will be organized into four clusters, covering countries in all regions of Europe.

OneNet is an open project that can finance further projects through cascade funding, thus welcoming new members into the consortium. OneNet calls for the creation of a unified vision for the European electricity market, inviting operators, consumers, and stakeholders from across Europe to contribute. To this end, the project will develop an open forum called "GRIFOn," a platform for free discussion of the project's findings with all relevant stakeholders outside the project.
