The EU-funded H2020 project PLATOON aims to digitalise the energy sector, enabling thus higher levels of operational excellence with the adoption of disrupting technologies. PLATOON will deploy distributed edge processing and data analytics technologies for optimized real-time energy system management in a simple way for the energy domain expert. The data governance among the different stakeholders for multi-party data exchange, coordination and cooperation in the energy value chain will be guaranteed via IDS based connectors. The project will develop and use the PLATOON reference architecture, which is COSMAG-compliant, for building and deploying scalable and replicable energy management solutions, contributing thus to increased renewable energy consumption, smart grids management, increased energy efficiency and optimised energy asset management, addressing the needs of various stakeholders along the value chain of the energy sector. The project will be validated in 7 pilots in 4 countries that provide real Energy Big Data cases. PLATOON will facilitate the technology transfer into the market by a well-established tendering process via Open Calls. PLATOON will reinforce the European efforts for the modernisation of the European electricity grid, as it focuses on new smart grids services through data knowledge exploitation. Moreover PLATOON will offer access to cheaper and sustainable energy for energy consumers and maximise social welfare. Thus PLATOON will contribute to increased renewable energy consumption, smart grids management, increased energy efficiency and optimised energy asset management.
