The market operator is providing further information on the opportunity for electricity day-ahead market participants in the Czech Republic to join the pan-European testing for the implementation of 15-minute products on the Single Day-Ahead Electricity Market. The testing will take place from April 7 to May 15 in the OTE Sandbox2 testing environment (OTE WebPortal).

Detailed instructions, test descriptions, and individual test scenarios can be found in the dedicated document, which can be accessed here.

During the testing, day-ahead market participants will have the opportunity to verify the processes and settings of their systems concerning the introduction of 15-minute products on the day-ahead market in the Czech Republic and Europe. We welcome the involvement of as many market participants as possible in the testing, as this collaborative testing effort will allow market operators and transmission system operators to refine and optimize the relevant processes. This will help ensure a seamless transition to this important change, which is scheduled for June 2025.
