After the successful integration of the Czech intraday electricity market into the Single Intraday Coupling (SIDC) in 2019 and enabling trading in 15-minute trading periods on the Czech-Slovak, Czech-German, and Czech-Austrian cross-border interconnectors in 2024, the trading period was successfully switched to 15-minute for the last Czech-Polish interconnector on March 18, 2025. This was completed in the implementation wave that also included transition to 15-minute in Norway (all bidding zones), Portugal, Spain, and Poland. At the same time, the Romanian-Hungarian and Romanian-Bulgarian borders were integrated into the European Intraday Auctions (IDA).

The successful rollout of the 15-minute MTU across nearly all of Europe’s internal bidding zones and interconnectors marks a major milestone. Years of collaboration, planning and technical innovation, combined with a carefully coordinated go-live windows approach, has ensured a smooth transition covering almost the whole European Intraday Market  from 18 March 2025.

Official press release regarding the successful implementation of 15-minute resolution across nearly all remaining internal bidding zones and their cross-border interconnectors in the Single Intraday Market in Europe can be found here.

This step also marks the successful completion of the transition to a 15-minute resolution on all Czech borders within the single intraday market.

The Greek borders will go-live in June, due to the Greek requirement that SDAC and SIDC go-live on 15-minute MTU, simultaneously.

The market operator is actively involved in integration activities that strengthen the electricity market in the Czech Republic while also enhancing the reliability of electricity supply to Czech customers. In the area of the Day-Ahead Electricity Market, the market operator is preparing the transition to trading 15-minute products within the framework of the European Single Day-Ahead Market.
