The fifth edition of the Energy Data Hackdays will take place on the 16th & 17th of September 2022 in Brugg, Switzerland. Energy companies, public administrations and other organisations related to the energy industry will make data available for the development of creative ideas and initial prototypes. The focus will be on industry-relevant topics like, among others, the energy grid as an interface to the smart communities, the role of the transmission grid in the decentralisation of the production sector, security of supply with a decentralised production, how to ensure data security or how to link network planning and urban development. The hackdays are as usual free and open to any person interested in helping to shape the future of energy.
