Survey on Ancillary Services Procurement and Electricity Balancing Market Design

​The survey provides support for the future implementation of the Network Code on Electricity Balancing (NC EB) and highlights the challenges facing the pan-European harmonisation of electricity balancing market design. The survey information is used to monitor the implementation of the NC EB and to report on the development towards a European balancing market.

The survey includes maps illustrating how different approaches have been taken to the design elements of Ancillary Services and Imbalance Charges across Europe.

  • Data collection is a relatively high-level exercise; therefore not all details are captured.
  • Different countries use different concepts. Hence the development of a single set of definitions encounters difficulty in matching the various concepts. Consequently, in a number of specific cases, the position of a country in a certain group might be debatable.
  • The survey builds on information updated in November 2013 and describes the mechanisms in place in 2013, so does not take into account any updates which might h ave occurred afterwards.
