Start date of the Core Flow-Based Intraday Capacity Calculation (c) EXT // run

On 17 December 2024, the external parallel run of the IDCC(c) process at 4:30 for continuous trading (MTU 6:00 – 24:00) will start, in line with Article 26(3)(b) of the Intraday Capacity Calculation Methodology. The first business day that will be covered by this external parallel run is BD20241217. The objective is to successfully complete the process and publish the results for all 7 business days of the week. Results will be published on the JAO Publication tool. During the external parallel run, which will have an expected duration of 6 months, Core TSOs will report on the stability of the process and the results towards stakeholders. 

Currently, Core TSOs are still finalising their individual validation tooling which could impact the capacities published during the early phase of the external parallel run. The tooling is expected to be ready in Q1 2025.

Market integration - Core to energy transition

The energy transition towards a carbon free electricity supply is a European challenge that requires the use of the European electricity system to the full extent. Weather-dependent supply and increasing demand response will lead to a different and more intense use of the grid. The Core market integration project is aiming to create operational preconditions to optimise
