Transition to a 15-minute settlement and trading period for the electricity commodity

Content:


With effect from July 1, 2024, 15-minute settlement period was successfully introduced on the electricity market, and cross-border trading of 15-minute products was launched both on the continuous intraday market and within intraday auctions. The next step was the introduction of trading in a 15-minute trading period on the single day-ahead electricity market as of delivery day 1 October 2025.
