An electric load is adjusted dependent on the line frequency of a power grid (energy supply grid), said line frequency being measured in the load itself. A building management system can thereby counteract a deviation from the target line frequency in a self-sufficient manner for example. Information can also be transmitted to the energy supplier, which then adjusts the load and can thus counteract a deviation from the target frequency. The invention allows an early and efficient detection of fluctuations of the line frequency in volatile regenerative energy sources for example. On this basis, countermeasures can be introduced at different (central) sites, for example in a control system (building or facility management system) or in the energy supplier.
