Coordinated curtailment of cross-zonal capacity
Article 25
1. TSOs shall coordinate curtailments of already allocated long-term cross-zonal capacity, if the curtailments concern a time frame of more than 48 hours ahead of the start of the delivery day. In case of curtailment of long-term transmission rights, including nominations in respect of such rights, within 48 hours ahead of the start of the delivery day, TSOs in each capacity calculation region shall apply the day-ahead and intraday capacity calculation process as referred in Article 29 of Regulation (EU) 2015/1222. 2. If a TSO needs to curtail already allocated long-term cross-zonal capacity, it shall send a request to the responsible coordinated capacity calculator to launch the coordinated calculation of necessary curtailments of long-term cross-zonal capacity for the capacity calculation region. The TSO shall support its request with all relevant information. 3. The coordinated capacity calculator shall provide the updated cross-zonal capacity to the relevant TSOs for validation. 4. Each TSO shall validate the updated cross-zonal capacity on its bidding zone borders or critical network elements pursuant to Article 24. 5. The coordinated capacity calculator shall provide the validated updated cross-zonal capacity to the relevant TSOs and single allocation platform to perform curtailment pursuant to Article 53.
