Transition to a 15-minute settlement period for the electricity commodity from July 1, 2024 in the Czech Republic
With effect from July 1, 2024, the Czech Republic will switch to a 15-minute clearing and settlement period for the electricity commodity. Documents relating to modifications to the market operator's information system in connection with this change, including anticipated modifications to external interfaces in connection with the transition to a 15-minute settlement and trading interval in the Czech Republic from the market operator's point of view, are continuously published on this website. Below is also the testing plan and the expected GoLive plan for the implementation of new functionalities in connection with the transition to a 15-minute settlement period for the electricity commodity.
