ACER to decide on the amendment of the intraday cross-border capacity calculation methodology for the Core region

What is it about?

The National Regulatory Authorities of the Core region asked the EU Agency for the Cooperation of Energy Regulators (ACER) to decide on the first amendment of the intraday capacity calculation methodology (LT CCM) for the region.

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

The Core day-ahead capacity calculation methodology includes a new approach for the long- term allocation (LTA) inclusion, called Extended LTA Inclusion (ELI). The proposed amendment allows the intraday capacity calculation to accommodate the principles of ELI approach and therefore enabling the compatibility of the day-ahead and intraday capacity calculation methodologies.

What are the next steps?

The ACER’s Decision 02/2019 will be amended to enable the harmonisation of the capacity calculation principles at intraday level with the Core day-ahead capacity calculation methodology.

To take an informed decision, ACER invites interested stakeholders to submit their views by 2 March 2022 to the email: ACER-ELE-2022-002(at)acer.europa.eu.

This amendment of the intraday capacity calculation methodology is the prerequisite for the implementation of the Core Day-ahead flow-based methodology. Therefore, it needs to be completed under the fast procedure, before the Core Day-ahead flow-based market coupling (Core FB MC) will go-live (20 April 2022).

ACER expects to reach its decision by 13 April 2022, before the Core Day-ahead flow-based capacity calculation methodology would enter into force.

What are the benefits?

The cross-border capacity calculation methodology promotes effective short‐term cross‐zonal trade.

The amended intraday capacity calculation methodology for the Core region will apply the flow-based approach, fully coordinated with the day-ahead flow-based capacity calculation approach.

The amended ACER’s Decision will contribute to the effectiveness and integration of the Core electricity markets by establishing the common rules for calculating the intraday cross-zonal capacity at regional level.
