The European Union launched an action plan for Digitalising the energy system in 2022 to promote connectivity and interoperability, foster co-ordinated investments in smart grid technologies, empower customers, enhance cyber security, promote greater efficiency, and. The EU is promoting the availability of safe, secure, and sustainable digital energy services. Digitalisation has an impact across the energy value chain, from generation to transport, distribution, supply and consumption. The system-wide digitalisation energy action plan aims to contribute to the EU energy policy objectives by supporting the development of a sustainable, (cyber)secure, transparent and competitive market for digital energy. Moreover, technologies such as Artificial Intelligence (AI), the Internet of Things (IoT), and blockchain are playing pivotal roles in optimizing energy efficiency and grid management. Equally important are customer-facing solutions, which are redefining how consumers interact with their energy.
