Control Area Imbalance
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:
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 “operational data” is based on measured data and is not as accurate as the measurements that are used for the settlement. “Data relevant for settlement” shows intermediate measured values after first data matching. The figures are replaced by final data relevant for settlement after matching and alignment processes with all involved partners.
Data published on the Pan-European Transparency-Platform are additionally updated with a delay of two months with final settlement values. These are equal to the data relevant for settlement published on APG website.
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.
A description of the values in the table and description of their use in imbalance price calculation can be found here.
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.
