PC_2023_E_06 - Public Consultation on ACER’s Decision on the amendments of Core region electricity intraday capacity calculation methodology

On 4 April 2023, the regulatory authorities of the Core capacity calculation region referred to ACER two proposals from the Transmission System Operators (TSOs) in their region for amendments to the Core region electricity intraday capacity calculation methodology.

Since June 2022, intraday capacity calculation methodology in the Core region is aligned with the day-ahead flow-based market coupling (see the original ACER Decision 02/2019 and the first amendment to the Decision 06/2022).

The two proposed amendments aim to align the intraday capacity calculation methodology in the Core region with the parallel Regional Operational Security Coordination process. This will enable more efficient functioning of intraday electricity market in Core region and its further alignment with parallel congestion management processes.

ACER intends to decide on the proposed amendments in cooperation with Core regulatory authorities and TSOs, and thus enable the first intraday flow-based capacity calculation in Europe. This will enable more efficient functioning of intraday electricity market in Core region and its further alignment with parallel congestion management processes.

The dates of the public consultation are approximate.

Public notice.

In order to make an informed and inclusive decision, ACER will collect inputs from stakeholders.

ACER will decide on the proposals for amending the Core intraday capacity calculation methodology by 4 October 2023.
