The energy system is undergoing a global transformation: centralized models are being replaced by decentralized, digitized solutions. New players and demands are placing an increasing burden on traditional grids, while security of supply and affordability are also becoming key factors. As flexible, scalable systems, microgrids can integrate various energy sources and storage, even independently of the public grid. In this way, they ensure an efficient, sustainable, and future-proof energy supply across a wide range of applications.
