HUPX proudly announces the successful go-live of the 15-minute market time unit (MTU) on its Day-Ahead Market. The first market results were published shortly after 1 p.m. on 30 September for the 96 quarter-hour periods of the delivery day on 1 October.

This implementation is part of the Single Day-Ahead Coupling (SDAC), covering the entire European market with the joint effort of  Nominated Electricity Market Operators (NEMOs) and Transmission System Operators (TSOs). The milestone represents an important step in the development of the European electricity market, ensuring finer trading granularity and compliance with EU regulatory requirements.

The transition to 15-minute market time unit represents a major  step forward in efficiency and flexibility. It enables more precise alignment of supply and demand, which is essential amid the growing variability of renewable generation. By allowing more dynamic short-term responses, the new product supports renewable integration, reduces reliance on fossil fuels, and highlights Europe’s commitment to the energy transition.

“For traders, the introduction of 15-minute products is a real breakthrough. It allows for more precise position optimization and a better response to short-term market dynamics, while 60-minute contracts remain available. The strong initial interest confirms the value of this flexibility.” - György Istvánffy, Director of Markets, HUPX

“This project is a true milestone for the European electricity market. The launch of the 15-minute product on the Day-Ahead Market demonstrates what close cooperation among NEMOs, TSOs, regulators, and market participants can achieve. It’s a decisive step toward a more efficient, flexible, and interconnected energy system ready to meet future challenges.” - Dr. Mátyás Vajta, CEO, HUPX
