Function Elia Group operates at the heart of the European electricity system as a critical infrastructure operator in Belgium and Germany. The ongoing energy transition and digital acceleration are profoundly transforming our technology landscape.

Traditional boundaries between Operational Technology (OT) and Information Technology (IT) are disappearing, while cloud platforms, real-time data, advanced analytics, and modern infrastructure technologies are becoming central to how we operate safely and efficiently.
