50Hertz maintains a constant balance between the production and consumption of energy within its grid area, in order to use energy efficiently. The settlement of all related activities is performed by the means of balancing groups. Below, we provide you with further information about the subdivision, settlement and management of balancing groups. On this page, you can also find an overview of important regulations and a link to download the standard balancing group contract.
Balancing groups function as virtual energy volume accounts in the energy industry. They connect the electricity market (virtual world) with the energy flow in the power grids (physical world) and serve as an instrument to control the efficient use and correct, consistent balancing of energy. As an interface between the physical energy flow and the trade on the electricity exchange, balancing groups are the means to establish the balance between energy generation and energy consumption.
The Balance Responsible Parties (BRP) are responsible for the management of the balancing groups. The BRPs undertake to maintain the balance of their balancing groups by means of physical generation and consumption as well as the balance of the virtual energy flow between balancing groups (commercial transactions).If this balance is not possible for the BRP, 50Hertz ensures the system stability by using balancing energy and compensates the difference of the surplus or deficit. This use of balancing energy is compensated in the balancing group settlement between the BRP and 50Hertz.
The contractual framework for the management of balancing groups is provided by the standard balance responsible contract published by the Federal Network Agency. The standard balancing group contract is used for contractual handling of all business transactions, such as trading, supply and grid activities. In this contract all relevant obligations of the contract parties up to the settlement of the accrued balancing energy are agreed upon. More detailed information about balancing group management and the right contact at 50Hertz can be found in ourcustumer brochure.
The operators of electricity supply grids are obliged to maintain a balancing group which exclusively comprises energy that is remunerated with a feed-in tariff in accordance with the Renewable Energy Sources Act (Erneuerbare-Energien-Gesetz, EEG) from suppliers in the grid area for transmission to the balancing group for energy in accordance with the Renewable Energy Sources Act of the operators of transmission grids. The obligation in the first sentence does not apply to system operators with less than 100,000 customers directly or indirectly connected to its distribution grid. (Extract from the Ordinance on Power System Access – StromNZV, §11)
On 1 November 2018, 1, 840 balancing groups were managed by a total of 645 contract partners in the grid area of 50Hertz Transmission GmbH.

On 18/06/2018, the TSOs requested the approval of the terms for Balance Responsible Parties in the form of the altered standard balancing group contract from the Federal Network Agency in accordance with art. 5 para. 4 c) in conjunction with art. 18 para. 1 b) and para. 6 EBGL. After approval, the proposal should completely replace the currently applicable standard balancing group contract (decision of ruling chamber 6 of 29/06/2011, ref. BK6-06-013).
Due to the multitude of balancing groups and their deviations, the occurring energy flows are counterbalanced. Only the remainder, i.e. the balance of all balancing group deviations (grid area balance), makes it necessary to use the procured balancing energy. The resulting costs are transferred to the balancing groups through the balancing group settlement.
The basis for the market communication prior to settlement is the presentation of a valid certificate. The process for balancing group settlement is laid down in the market rules for the balancing group settlement for electricity (MaBiS). This also determines the data exchange deadlines for the preparation of the settlement.
The standard cross-grid area balancing energy price (reBAP) applies to all German grid areas since May 2010.
In addition to the reBAP, the relevant balance of the used grid energy is also mentioned for each quarter-hour of the grid areas participating in the GCC (GCC balance). A plus sign corresponds to the purchase of positive grid energy due to deficient coverage of grid areas whereas a negative sign corresponds to the purchase of negative grid energy (delivery of surplus energy) in case of excess cover of the affected grid areas.
Pursuant to the resolution BK6-12-024 of the Federal Network Agency of 25/10/2012 and the associated description of the model to calculate the reBAP, the costs of the balancing energy used to balance the grid area, the revenues from the balancing group settlement, the revenue surplus for the reduction of grid charges and the further allocation of higher/lower revenues are presented on a delta account. The delta account consists of corrections referring to the past, resulting e.g. from belated claims of balancing energy suppliers that could not yet be cleared at the time of the reBAP publication.

In general, the grid of a distribution system operator (DSO) is one balancing area. Additionally a DSO balancing area can also include several definable metering grids of one DSO (but not of several DSOs!). The balancing coordinator, i.e. the transmission system operator (TSO), issues EIC identifiers for the DSO balancing areas to the DSOs and manages the DSO balancing area structure of a grid area for the plausibility check of the grid balances. In this context, each TSO acts as representative of the national EIC authority for its grid area.

The balancing areas of the 50Hertz grid area are published by 50Hertz as the balancing coordinator (TSO) with their EIC identification, the allocated DSOs (ILN/BDEW-Code-Nr.) and their scope of validity.
In addition, the German Energy and Water Association (BDEW) provides a merged list of all TSOs:
EIC codes for DSO balancing areas
The financial balance of 50Hertz results from the comparison of the balancing energy costs for balancing of the grid area and the revenue from the balancing group settlement, taking into account a financial compensation from surplus income and revised amounts (delta account). The calculation is described in the model for the calculation of the reBAP. The balance, which represents the financial equilibrium, is given for each month in the table below. The values are extended with a delay of three months.
The transmission system operators (TSOs) require the balances of all commercial transactions in the relevant grid area in the form of schedules between balancing groups in order to guarantee the correspondence between generation and consumption. To this end, the Balance Responsible Party (BRP) declares its expected energy deliveries for the next day to the TSO no later than 2:30 PM the previous day.

Subsequent changes to the internal grid area schedules have to be received no later than 4 PM of the next (business) day (see Ordinance on Power System Access – StromNZV, §5 para. 3, Download).
A business day is considered any day from Monday to and including Friday, with the exception of official holidays:
