ACER’s decision ensures the intraday capacity calculation methodology of the Core region is aligned with the expected flow-based market coupling

Intro News

ACER has reached a decision on the first amendment of the intraday capacity calculation methodology of the Core capacity calculation region (Core ID CCM) in cooperation with the region’s NRAs and TSOs.

ACER’s decision ensures the intraday capacity calculation methodology of the Core region is aligned with the expected flow-based market coupling

What is it about?

The EU Agency for the Cooperation of Energy Regulators (ACER) has reached a decision on the first amendment of the intraday capacity calculation methodology of the Core capacity calculation region (Core ID CCM) in cooperation with the region’s National Regulatory Authorities (NRAs) and Transmission System Operators (TSOs).

The Core region comprises 13 Member States: Austria, Belgium, Czech Republic, Croatia, France, Germany, Hungary, Luxemburg, the Netherlands, Poland, Romania, Slovakia and Slovenia.

ACER amended its original Decision 02-2019 so as to enable the harmonisation of the capacity calculation principles at intraday level with the day-ahead capacity calculation methodology of the Core region.

ACER’s new Decision 06-2022 ensures that the application of the intraday capacity calculation methodology of the Core region is aligned with the expected Core Region day-ahead flow-based market coupling. The latter was expected to go live on 20th April but has once again been postponed.

The decision focuses mainly on the intraday transmission capacities in the transitional implementation period of one year. These are residual capacities after the single day-ahead market coupling (SDAC) process.

How did ACER contribute?

In February 2022, the regulatory authorities of the Core region asked ACER to decide on the intraday capacity calculation methodology.

ACER has carried out assessments and consulted relevant stakeholders to take an informed decision on any needed adjustments.

On this basis, ACER has amended the initial proposal of the 1st amendment of the Core ID CCM provided by the Core TSOs so as to further improve the efficiency, transparency and non-discriminatory principles of the intraday capacity calculation process, as well as to ensure its compatibility with day-ahead markets.
