ACER’s 2024 report finds that congestion progressively diminished in 2023. However, the repercussions of the gas market crisis remain clear, as price convergence between European gas hubs has not yet reached the pre-crisis levels.
In August 2025, ACER has received a proposal from NEMOs to amend the harmonised maximum and minimum clearing price methodologies for the EU day-ahead and intraday market coupling. On 4 January 2026, ACER has approved the proposal.
ACER publishes its Opinion on the Integrated Model report for EU electricity, gas and hydrogen infrastructure planning, submitted in October by ENTSO-E and ENTSOG and prepared with support from ENNOH.
