Today, ACER releases its Opinion on the All-Island Resource Adequacy Assessments for Ireland, Northern Ireland and the Single Electricity Market (SEM) as a whole.
ACER published its Opinions on requests from seven national regulatory authorities on derogations from applying EU gas network codes and guidelines at interconnection points with third countries.
ACER approves the European Resource Adequacy Assessment proposed by the European Network of Transmission System Operators for Electricity (ENTSO-E) for 2025 (ERAA 2025), but raises concerns about its robustness.
ACER's latest gas Monitoring Report covers trends in winter 2025-2026. It also explores the impact of evolving Middle East conflict and the closure of the Strait of Hormuz on European gas markets.
The dataset provides economic parameters for new electricity resources, including estimated capital and operational costs for different power generation technologies and demand-side flexibility.
On 21 July 2026, ACER received a proposal from all nominated electricity market operators to amend the methodology for the price coupling, continuous trading matching and intraday auction algorithms. ACER will decide by 21 January 2027.
