Today, ACER opens two public consultations on:
- economic input data to improve European electricity system modelling; and
- amendments to the Core region's long-term capacity calculation methodology.
The consultation on economic input data for European electricity system modelling presents a new dataset on estimated investment and operational costs for various power generation technologies and demand-side flexibility at Member State level. Stakeholders are invited to review the data and provide feedback to improve its accuracy and reliability, contributing to strengthening the EU adequacy framework.
The aim is to ensure that assumptions used to assess investment in power system resources are robust, transparent and firmly grounded in national market realities.
The consultation on amendments to the Core region’s long-term capacity calculation methodology aims to inform ACER’s decision on the proposed changes to enhance long-term capacity calculation. The transmission system operators propose enabling the implementation of the flow-based methodology and integrating the Ireland-Northern Ireland single electricity market - France bidding zone border into the Core region’s long-term capacity calculation process.
Both consultations will run until 27 March 2026.
