Internet of Things (IoT)-enabled solutions for smart energy and utilities connect sustainable energy assets. Integrate them into IT infrastructure to improve energy efficiency and delivery from production to consumer. Smart meters provide real-time energy availability and consumption. The InEExS roadmap confronts outdated systems with smart tech, blockchain, and bold policy reform—offering a clear path to a cleaner, more connected, and consumer-driven energy landscape. The topic of “digitalization of energy systems” combines established structures and an excellent reputation in many institutes of the Fraunhofer ICT Group and the Fraunhofer Group for Energy, Technologies and Climate Protection. 6 petawatt-hours (PWH) in 2030.
