Balancing the grid

The system operators of the Elia Group (Elia in Belgium, 50Hertz in Germany) constantly oversee and ensure balance in their control area. Since electrical energy cannot be stored on a large scale, balance must be maintained continually and in real time between generation and consumption.

Elia Group’s grids are part of the European continental interconnected system from Portugal to Bulgaria and from Norway to Italy. The control centers of the Elia Group manage an instantaneous balance and coordinate energy flows on their grids in close collaboration with international coordination initiatives (e.g. Coreso, TSO Security Cooperation) and transmission system operators from neighbouring countries.
