Control energy (activated balance energy)

50Hertz publishes the activated reserve power as quarter-hourly averages, categorised in secondary control reserve (SCR) and minute reserve (MR).

While secondary control reserve is automatically activated and used continuously, minute reserve is activated manually in the ¼ h time resolution of schedules to support or even substitute secondary control reserve.

Secondary control reserve and minute reserve are generally activated on the basis of a federal Merit Order List (MOL). Deviations from the Germany-wide MOLs are published on www.regelleistung.net.

As a result of the activation in accordance with federal MOLs, there is a continuous exchange of secondary control reserve and minute reserve activated within the German control areas. The time series of applied secondary control reserve and minute reserve published here correspond with the secondary control reserve or minute reserve activated in the 50Hertz control area.

15-minute control area balance 2014

The control area balance is calculated based on the sum of all deviations occurring within an individual balancing group. For this calculation, the deviations are derived from the supplied schedules as well as the actual consumption of electricity and the actual feed-in by power plants.

The control area balance is given as the average power, expressed in megawatts (MW), for each quarter-hour. To increase the quality of the data, 50Hertz reserves the right to update the published values at any given time.

Please note that the rule determining plus or minus that applies to the data was changed on 1 May 2009:
A positive control area balance signifies an energy balance deficit in the control area (deficient cover). A negative control area balance represents an energy balance surplus in the control area (excess cover).

Historical data can be found in the archive.

Activated secondary control power

Positive values represent an activation of positive sekundary control power (increasing production or decreasing load).

Control area balance

The control area balance is calculated based on the sum of all deviations occurring within an individual balancing group. For this calculation, the deviations are derived from the submitted schedules as well as the actual consumption of electricity and the actual feed-in by power plants.

The control area balance is given as the average power, expressed in megawatts (MW), per quarter of an hour. To increase the quality of the data, 50Hertz can update the published values at any given time.

Please note that the rule determining plus or minus that applies to the data was changed on 1 May 2009: a positive control area balance signifies an energy balance deficit in the control area (deficient cover). A negative control area balance represents an energy balance surplus in the control area (excess cover).
