Coordinated Capacity Calculation (CCC) plays an important role in the European interconnected system. Indeed, electricity exchanges are now part of daily business and flowing across Europe, crossing borders. In order to make this possible and to ensure the security of the electrical system, a preparation is needed before electricity delivery. This is the role played by Coreso as nominated Capacity Calculation Coordinator for three regions (CORE, SWE and Italy North) in Europe.

As RSC and future RCC, Coreso calculates the cross-border capacities between countries using technical data from Transmission System Operators (TSOs).  Furthermore, after optimisation and ensuring the security of the EU grid, we provide the results (cross-border capacities) to the market energy platforms. On these power exchange platforms, market parties can trade using a secure space to exchange energy within European grid.

Concretely, the CCC service consists in:

  • Applying approved regional coordinated methodologies to compute parameters defining available capacity (either Net Transfer Capacity (NTC) or Flow Based (FB) parameters), based on CGM. The previously mentioned methodologies aim at optimizing cross-border capacities while ensuring coordinated security;
  • Providing improvement proposals to optimise computation quality and/or available cross-border capacity

This CCC service is requested for the following timeframes: day-ahead, intraday capacity and long-term (yearly and monthly). Coreso must perform this service for South-West Europe (SWE) Capacity Calculation Region (CCR) as well as for the Italy North CCR and CORE CRR in collaboration with TSCNET.

This service is still under development. Therefore, the above explanations may be amended after the full development of this service takes place.
