The European energy market is undergoing a significant transformation with the planned implementation of a 15-minute Market Time Unit (MTU) in the Single Day-Ahead Coupling (SDAC) by June 2025. More specifically, starting June 11, 2025 (for delivery date June 12, 2025) the Market Time Unit (MTU) in the Single Day-Ahead Coupling will move to a 15-minute resolution. At the same time, products with a 15-min and 30-min resolution will become available for trading in the continuous intraday market in the Greek bidding zone.
Relevant public consultations on the adjustments needed in the regulatory framework, following the relevant proposals of the Hellenic Energy Exchange (HEnEx S.A.), the Independent Power Transmission Operator (IPTO S.A.), and the EnΕx Clearing House Single Member S.A. (EnExClear S.A.) have either been concluded or are on-going. The Authority plans to issue the relevant decisions within the month of May.
In view of the above, we urge all Market Participants to participate actively in the testing activities currently conducted by HENEX and IPTO to confirm the compatibility of their internal systems with the new system functionalities. It will also ensure familiarity with the relevant procedures and any changes that may affect their operations.
This is a valuable opportunity to validate critical processes such as order management, trade execution, results publication, and asset position monitoring. By thoroughly exploring these areas now, a smooth transition and minimization of any disruptions prior to the Go Live can be assured.
RAAEY strongly encourages market participants to begin testing as soon as possible, as this will help identify any potential issues early on and facilitate a smooth transition.
Please contact HEnEx and IPTO for further information.
