Balancing Group Price

Unfortunately, the publication of prices for balancing group deviations may be delayed at the moment. The delays result from the conversion to PICASSO, the commissioning of the target market design and the implementation of the Imbalance Settlement Harmonisation Methodology. Due to system adjustments, there are delays in the provision of data. We apologise for the inconvenience. We are working on publishing the data as soon as possible. Once the problems have been solved, the data will again be published on time on the 20th working day of the following month. The publication of the data is now also available at  https://www.netztransparenz.de/Daten-zur-Regelenergie/reBAP/reBAP.

The demand for control power (of the balancing groups) corresponds to the total sum of deviations between the reported schedules and actual customer consumption or actual power plant in-feed. It is recorded on a quarter-hourly basis as a mean demand value by the control area balance responsible party of the TSO. Settlement with the balancing groups is on a quarter-hourly basis, using the (agreed) mean kilowatt-hour rates for unscheduled power flow.

For the regarded quarterly hour, the balancing group price results from the application costs for control power divided by the balance of control power relevant for settlement. Additionally the price’s absolute value is capped to the maximum application price of all utilized control power tenders.

A low control area balance does not necessarily imply the use of a small amount of control power. And this does not mean automatically low costs and low prices. This is due to the fact that within a quarter of an hour a change of direction between positive and negative secondary control power might be required.

The existing grid control cooperative (GCC) was expanded on 1st May 2010. Since that the GCC consists of the following four TSOs: 50Hertz Transmission GmbH, Amprion GmbH, EnBW Transportnetze AG and transpower stromübertragungs gmbh.

In the context of the GCC, the TSOs have introduced a standardized price for balance energy (reBAP). This means that the same price for balance energy is applied in the four control areas participating in the grid control cooperative for each ¼ hour. The reBAP is primarily calculated by taking into account the total cost for the utilized balance energy by the total amount of utilized balance energy of each ¼ hour.

In addition to the reBAP, the total of the utilized balance energy is listed for each ¼ hour of the participating control areas.

A positive sign corresponds to the purchase of positive balance energy. A negative sign corresponds to the purchase of negative balance energy (discharge of surplus energy).

Further information to the balance-energy-price is published under the heading “Important info”.

Note: The operational control area balance published on this page currently still uses the old calculation formula that was replaced on June 22nd, 2022. For further information about the change of the calculation formula, please see  www.regelleistung.net.

Until the changeover on this page has been implemented, please use the time series of the operational control area balance published on  www.regelleistung.net or  www.netztransparenz.de.

We will inform you here as soon as the change has also taken place on this page.
