The 50Hertz transmission system is the basis for a reliable, secure and efficient electricity supply. The secure supply is at the centre of our activities. Should grid stability be endangered or disrupted, we immediately take grid- or market-related measures in the scope of congestion management.
The preventive or curative measures include redispatch and counter trading to adjust power feed-in (§13 paragraph 1 EnWG). The volumes indicated for the measures under §13 paragraph 1 EnWG are defined as the sum of all capacity increases as well as the sum of all capacity reductions in the time interval.
If the measures mentioned above cannot prevent a risk or solve a failure or not in time, the system operator is entitled and obliged to adjust all feed-in, transit and consumption of electricity to meet the requirements for secure and reliable operation or to request such an adjustment (§ 13 paragraph 2 EnWG in conjunction with §14 EEG). The measures described as per §13 paragraph 2 EnWG in conjunction with §14 EEG exclusively concern capacity reductions.
Note: the volumes given are based on power plant schedules. In this context, redispatch volumes are determined as the sum of the energy exchange between 50Hertz and the power plants within the control area. Stock exchange transactions to balance the redispatch balancing group and redispatch measures with domestic or foreign transmission system operators are not included.
