Ljubljana, 15 March 2024
In April 2023, the regulatory authorities of the Core capacity calculation region referred to ACER two proposals from the Transmission System Operators (TSOs) to amend the Core region’s Intraday Capacity Calculation Methodology (Core ID CCM).
After extensive discussions with Core TSOs and regulatory authorities, and having consulted with stakeholders in summer 2023, ACER has decided to approve the proposals, with some amendments.
What’s new?
The TSOs have proposed two amendments with the following objectives:
- Ensure the methodology aligns with the parallel Regional Operational Security Coordination (ROSC) process.
- Temporarily introduce the Available Transfer Capacity (ATC) as an additional validation solution (on top of the flow-based validation) to check the amount of electricity that can be safely traded across borders.
By approving these amendments, ACER will facilitate the first implementation of intraday flow-based capacity calculation in Europe. This will enhance the efficiency of the intraday electricity market in the Core region and its further alignment with the congestion management process.
What are the next steps?
The first intraday flow-based capacity calculations are to be implemented by early July 2024.
