While the electrical grid is moving from being a fully centralized to a highly decentralized system, grid operators have to change their operative business to accommodate for faster reactions and adaptive exploitation of flexibility. The topic has been subject of several research projects in the past years and reached a maturity that allows now the consideration of a final level, proposing an integrated view on the grid operations beyond the traditional barriers. OneNet aims at performing this critical step creating the conditions for a new generation of grid services able to fully exploit demand response, storage and distributed generation while creating fair, transparent and open conditions for the consumer. As result, while creating one network of Europe, the project aims to build a customer centric approach to grid operation. This ambitious view is achieved by proposing new markets, products and services and by creating a unique IT architecture. While a single platform for Europe is not thinkable, OneNet proposes innovative mechanisms of platform federation which are the key technical enablers for the proposed vision. The project has also very ambitious exploitation goals aiming at creating consensus on the solution far beyond the limits of the consortium partners thanks to a variety of actions including a large-scale forum for discussion within the international energy community. The complete concept is also proven in 4 cluster demos creating an involvement of an unprecedented number of countries and their grid operators in a single project. The consortium, in addition to a significant list of grid operators, includes also key IT players, leading research institutions and the two most relevant associations for grid operators, jointly providing a unique set of expertise in support to these challenging tasks.
