On this page, the four transmission system operators present the GCC balance traffic light. This shows the current system balance status with a short time delay. The value of the German GCC balance for the last few minutes is calculated and set in relation to the dimensioned control power.
The value of the GCC balance traffic light is determined on the basis of defined limit values and displayed in the stages red (positive), yellow (positive), green (positive), blue, green (negative), yellow (negative) and red (negative). The blue deadband does not show any information of the direction of the GCC balance. In particular, the aim is to ensure that the GCC balance traffic light displays correct signals even with small GCC balances and the associated frequent sign changes.
Positive GCC balance traffic light signals mean that there is a deficit in the system, negative GCC balance traffic light signals mean that there is a surplus in the system.
