For a stable electricity system in the 50Hertz control area, we ensure the balance between electricity consumption and electricity generation at any given time. The control energy needed to do this is - like energy to recover electric system losses - procured through transparent tender procedures. We thereby facilitate fair and non-discriminatory competition.
Unforeseen variations must be set off with control energy within short response times, failing which the stability of frequency would not be ensured. Control energy is mostly procured from power plants that keep spare reserve capacity precisely for this purpose. A distinction is made between primary control power, secondary control power and minutes reserve.
50Hertz procures the energy making up for electric system losses through tender procedures to guarantee a market-oriented, transparent and non-discriminatory approach. For all information relevant for tendering, please go to
The Grid Control Cooperation (GCC) was expanded to include all four German transmission system operators (TSOs) in May 2010. A single price for compensation energy common to all control areas (reBAP) and previously applicable in three German control areas is now used in all control areas in Germany. more
