The introduction of 15-minute continuous trading products in the day-ahead market, preparations for which are in full swing, according to energypress sources, would reduce balancing costs and also offer better terms for the renewable sector’s penetration of the energy mix.

However, the transition to 15-minute continuous trading products in the day-ahead market, planned to take place simultaneously across Europe in 2025, promises to be a demanding task for all parties involved.

The Greek Energy Exchange, as a key player in the domestic implementation of the project, has already begun relevant preparations to adapt and improve all its systems in order to be able to support related transactions.

Power grid operator IPTO will need to take similar action for its infrastructure, and at grid interconnections, to ensure transactions flow smoothly amid conditions in which 15-minute products will play dominant roles in the day-ahead and intraday markets.

Indeed, Greece’s unique position with both coupled (Bulgaria, Italy) and non-coupled (Albania, North Macedonia, Turkey) neighboring electricity markets presents a challenge that requires special provisions.

Special attention will be needed so that 15-minute continuous trading products can also apply for non-coupled markets, otherwise the Greek market will be obliged to maintain 60-minute products, as is the case at present, in order to trade electricity in the day-ahead market with non-coupled markets.
