CORE Coordinated Validation tool

he Core Capacity Calculation Region is a collaboration between Transmission System Operators (TSOs) in Central Europe and Ireland with the aim to implement relevant regional methodologies of the guidelines following the Thrid Energy Package. The Core Day-Ahead Flow-Based Capacity Calculation methodology defines how cross-zonal capacities are calculated in the Core Capacity Calculation Region in the day-ahead market timeframe. The resulting cross-zonal capacities are used by Nominated Electricity Market Operators to perform market coupling and consequently determine the day-ahead wholesale power prices across the EU. The computation of cross-zonal capacities according to the Core Day-Ahead Capacity Calculation Methodology is done by the Core Capacity Calculation Tool and validated by the Core TSOs. Coordinated Validation takes place with the aim to validate cross-zonal capacities in a coordinated manner while maintaining operational security. If available remedial actions are not sufficient to solve any detected operational security violations, a Coordinated Validation Adjustment will have to be applied to reduce cross-zonal capacities. Thanks to its coordinated nature, the cross-zonal benefit of remedial actions for ensuring cross-zonal capacity can be considered in the Coordinated Validation step of the Day-Ahead Capacity Calculation, in alignment with closer to real-time operational planning processes. To perform the Coordinated Validation of the Core Day-Ahead Capacity Calculation process, the Core TSOs seek to contract a supplier who can deliver and implement a tool to establish this validation step within the process.
