CORE Coordinated Validation tool

he Core Capacity Calculation Region is a collaboration between Transmission System Operators (TS Os) 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 TS Os.

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 TS Os seek to contract a supplier who can deliver and implement a tool to establish this validation step within the process.
