ACER to consult on the methodology for electricity intraday flow-based capacity calculation in the Core region
What is it about?
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.
Why change the rules?
Since June 2022, intraday capacity calculation methodology in the Core region is based on a flow-based approach and 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 Core region comprises 13 Member States: Austria, Belgium, Czech Republic, Croatia, France, Germany, Hungary, Luxembourg, the Netherlands, Poland, Romania, Slovakia and Slovenia.
The TSOs of the Core region proposed two amendments to the intraday capacity calculation methodology to align it with the parallel Regional Operational Security Coordination (ROSC) process.
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.
What are the next steps?
ACER public consultation runs from 4 July to 1 August 2023.
ACER will decide on the amendments by 4 October 2023.
