Running a secure electricity system

The core tasks of each transmission system operator is to permanently ensure a balanced grid frequency, a stable voltage level and a reliable system while taking into account multiple major and fast changing challenges. In order to cope with the challenges of the energy revolution, all companies of the Elia Group (Elia, 50Hertz and EGI) develop solutions and procedures for greater flexibility, but also adapt the management of their electricity systems.

Besides the importance of regional cooperation with distrubtion system operators, producers and even consumers, system operation gets an increasingly international dimension. Real time cooperation at international level becomes more and more important.
