Services

• 

  CGM

  Create a pan-European overview of the interconnected European grid by collecting, checking the quality, and merging the Individual Grid Models provided by TSOs.

• 

  CSA

  Perform coordinated security analysis to assess the operational security of the transmission system and agree on the remedial actions needed to maintain it.

  See more
• 

  CCC

  Calculate the available cross-zonal transmission capacities that can be allocated to the electricity market. Provide proposals to TSOs to optimise available capacities.

  See more
• 

  STA

  Perform adequacy assessments to detect situations where a lack of electricity adequacy is expected. Propose and coordinate solutions for TSOs to ensure generation meets consumption.

  See more
• 

  OPC

  Identify tie-lines inconsistencies and outage planning incompatibilities between grid assets, with cross-border impact. Propose and coordinate solutions for TSOs to solve them.

  See more
• 

  Defence and Restoration Plans

  Review of TSOs’ defence plans and restoration plans (to be implemented in case of an emergency restoration state) to identify potential inconsistencies. Propose mitigation actions.

• 

  Training and certification

  Train and certify staff working for RCCs. Put in place an internal structure to train and certify operators while allowing traceability and transparency.

  See more
• 

  Regional Restoration

  Support the coordination and optimisation of regional restoration as requested by TSOs. Task definition still in discussion at European level while RCC involvement needs to be determined.

• 

  Post-Operation Analysis

  Carry out post-operation and postdisturbances analysis and reporting. Investigate and prepare reports on incident strongly affecting the European transmission network, to support the European expert panel for further analysis.

  See more
• 

  Sizing of Reserve

  Regional sizing of reserve capacity.

• 

  Procurement of Balancing Capacity

  Facilitate the regional procurement of balancing capacity.

• 

  Inter-TSOs Settlement

  Support TSOs, at their request, in the optimisation of inter-transmission system operators’ settlement.

• 

  Crisis Scenario

  Support ENTSO-E in the identification of regional electricity crisis scenarios.

• 

  Maximum Entry Capacity

  Calculate the value for the maximum entry capacity available for the participation of foreign capacity in capacity mechanisms for the purposes of issuing a recommendation.

• 

  Supporting Ten-Year Network Development Plan

  Carry out tasks related to supporting TSOs in the identification of needs for new transmission capacity, for upgrade of existing transmission capacity or their alternatives.

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.
