Automatic Frequency Restoration Reserve (aFRR)

The Automatic Frequency Restoration Reserve is activated automatically to balance the control area imbalance. The average values that occurred within a quarter of an hour in the APG control area are shown on this page. They are normally published within minutes after each quarter of an hour. An update is provided at a later point in time.

Further information about the shown Imbalance-Netting-Cooperations (INC, IGCC) can be found here.

A detailed description of the values in the table can be found here.

The information about decoupling of the aFRR-Cooperation Germany/Austria displayed in the visualization starts with 01/01/17.

Note: A "decoupling of the aFRR-Cooperation Germany / Austria" (separation of the two local merit orders) is used if either the cooperation is manually decoupled or if the available transmission capacity (ATC) between Germany and Austria is zero.
