As Regional Coordination Centre (RCC), the services or tasks Coreso provides to nationally regulated TSOs are driven by European regulations.

Coreso is currently implementing and executing the following six historical coordination tasks foreseen by the European network codes in the Third Energy Package.

  • Common Grid Model (CGM),
  • Coordinated Security Analysis (CSA),
  • Coordinated Capacity Calculation (CCC),
  • Short-Term Adequacy forecast (STA),
  • Outage Planning Coordination (OPC),
  • Defence and restoration plans.


Following Coreso’s transition from Regional Security Coordinator (RSC) to Regional Coordination Centre (RCC) in 2022, additional tasks have been added to our task portfolio:

  • Training and certification of RCC staff (Training and certification),
  • Post-operation and post-disturbances analysis and reporting (Post-operation analysis).
  • Regional restoration at request of TSOs (Regional restoration),
  • Regional sizing of reserve capacity (Sizing of reserve),
  • Regional procurement of balancing capacity (Procurement of balancing capacity),
  • Optimisation of inter-TSOs’ settlement at request of TSOs (Inter-TSOs’ settlement),
  • Identification of regional electricity crisis scenarios (Crisis scenario),
  • Maximum entry capacity mechanisms (MEC),
  • Supporting Ten-Year Network Development Plan (TYNDP).

The Clean Energy Package requires us to develop and deliver these new services to foster cooperation of Transmission System Operators (TSOs) in Europe. For these new RCC tasks, ENTSO-E is mandated to develop a proposal for each of these, and to submit them to the Agency for the Cooperation of Energy Regulators (ACER). The timeframe for the implementation of the new tasks is set out in each of the approved proposals.
