The European power sector is undergoing a period of rapid transformation. Power generation has become progressively more decarbonised, distributed and renewable. Wind power and solar photovoltaics have formed part of this trend and will continue to dominate in the future. As these sources increase in market share, so too will the volatility of the power system supply-side. In parallel, power systems are increasingly digitalised and interconnected with other sectors and infrastructure. Information Communication Technologies (ICT) have opened new possibilities in the active management of power systems and strengthened the ability of the demand side to react to changes to the price of electricity. Standards offer the technical foundation for this transition. Our goal is to ensure a clean, smart and secure power system.
