Markets

Nowadays, the tasks of a transmission system operator exceed the responsibility for grid development and grid operations. As the coordinator of the balancing group, trustee of the EEG and responsible party for the control energy market, we have a key role in enabling secure and efficient power trading. We commit ourselves to implementing the single European market and providing the generation capacity required for system operations in as cost-efficient a manner as possible. In all these roles, we maintain a constant dialogue with political decision-makers and dedicate ourselves to further developing the framework conditions in order to guarantee market-oriented, efficient and secure system operation in the future as well.

In May 2010, the grid control cooperation (GCC) was expanded to include all four German transmission system operators (TSOs). The standard cross-control area balancing energy price (reBAP) now applies to all German control areas instead of the three as was previously the case.

Grid losses

Grid losses

Grid losses naturally occur when transforming and transmitting electricity. 50Hertz procures the electricity needed to cover these losses on the established wholesale markets.

The Grid Control Cooperation (GCC)

Germany has four transmission system operators responsible for balancing electricity feeding and take-off in their respective service territories. The past had seen situations where a power surplus in one of the service territories and a power deficit in another were regulated independently of each other. Since 01 May 2010, the four transmission system operators have joined forces and cooperate on a system control platform called Grid Control Cooperation (GCC). Balancing operations in the respective service territories are now jointly controlled based on a big-picture view, which saves control power and makes electricity supply in Germany even more secure.

Control energy

To balance unexpected fluctuations in the generation or consumption of electricity, the transmission system operators use control energy.
In order to have enough capacity available at all times, balancing capacity is tendered via the procurement platform www.regelleistung.net. Only pre-qualified bidders can participate in the tender (Link).
If necessary, the reserved capacity is activated as control energy and billed to the access responsible party as balancing energy (balancing group settlement).
