The Control Area Imbalance is the surplus or deficit of electrical energy in the APG control area. It equals the algebraic sum of all balance groups deviations (balancing energy). At the same time the control area imbalance is calculated from the algebraic sum of the following components:
- Automatic Frequency Restoration Reserve
- Manual Frequency Restoration Reserve
- Unintended exchange with the Continental European synchronous network
The average quarter-hour values of the control area imbalance and the requested Manual Frequency Restoration Reserve in MW are usually published shortly after the end of each quarter of an hour. The illustrated data is based on measured data and is not as accurate as the measurements that are used for the settlement.
Data published on the Pan-European Transparency-Platform are additionally updated with a delay of two months with final settlement values.
The values of the control area imbalance published on this site are marked with the inverse sign as published on the Pan-European Transparency-Platform.
Due to technical problems, incorrect values for the activated manual Frequency Restoration Reserve (mFRR) in this visualization can currently occur!
We kindly ask temporarily to use only the values in this visualization.
