In November 2023, ACER received a proposal from Nominated Electricity Market Operators (NEMOs) for amending the ACER’s 2020 methodology for the price coupling algorithm and the continuous trading matching algorithm.
Amending the methodology, in particular the day-ahead coupling algorithm, is needed to enable a co-optimised allocation of cross-zonal capacity for the exchange of balancing capacity or sharing of reserves. This would facilitate the integration of the balancing capacity markets and allow for a more efficient use of cross-zonal capacity.
Where does ACER stand in the process?
Following the receipt of the NEMOs’ proposal in November 2023, ACER initiated a procedure to decide on the proposed amendments. To collect inputs from relevant stakeholders and inform its decision-making process, ACER ran a public consultation and hosted a workshop in early 2024.
In October 2023, ACER commissioned a study to explore the benefits of implementing co-optimisation in the day-ahead coupling algorithm as compared to the current market design. To gather stakeholders’ perspectives on the study’s outcomes and identify further research and development necessary for implementing co-optimisation, ACER will hold a public consultation (from 27 May to 19 June 2024) and organise a webinar on 10 June 2024.
ACER will consider the consultation and webinar outcomes when drafting the proposed amendments to the methodology.
What are the key dates?
- Publication of the consultancy study: 27 May 2024.
- ACER public consultation: 27 May 2024 - 19 June 2024.
- ACER webinar: 10 June 2024.
ACER expects to decide on the amended methodology for the price coupling algorithm and the continuous trading matching algorithm by early autumn 2024.
