30 September 2025. EPEX SPOT announces the go-live of the 15-minute Market Time Unit (MTU) on its coupled Day-Ahead markets. Market results were published at 13:08 for delivery on the 96 quarter-hours of 1 October 2025 (delivery day), with prices and volumes in line with market conditions. The launch covered, on EPEX SPOT side, 11 countries (except Great Britain and Swizterland).
The rollout is part of the Europe-wide Single Day-Ahead Coupling (SDAC) and initiated jointly by the Nominated Electricity Market Operators (NEMOs) and Transmission System Operators (TSOs) of the Market Coupling Steering Committee (MCSC). This milestone marks a key step in the European electricity market’s evolution, supporting finer granularity in trading and aligning with EU regulatory requirements.
Pierre Milon, Executive Expert Market Coupling and Integration comments: "The first market coupling session with 15 minute products in Day-Ahead went very well. A significant amount of orders were submitted in 15-minute granularity on EPEX SPOT - 60 minute contracts remain available to our trading members. During this first session, there was a high interest in usage of the 15-minute products. Market Results were in line with market fundamentals, with a slight increase in market activity for this session on our platform."
