With the increasing integration of RES into the Greek electricity market, short-term flexibility mechanisms are essential for balancing supply and demand. Significant RES curtailment and price volatility in 2024 highlighted the system’s limited ability to adapt to real-time fluctuations. The upcoming 15-minute MTU implementation in June 2025 aims to improve market responsiveness and align with broader European market integration efforts. This paper investigates the operational effectiveness of flexibility tools in the DAM and IDM, focusing on the role of structured auctions (IDA 1-3) and continuous trading via the XBID platform. Using detailed data from January to March 2025, sourced from the HEnEx and the IPTO, the study examines daily volumes, responsiveness to MCP volatility, and RES curtailment patterns. Key performance indicators include the correlation between market price movements, intraday activity and the volume dynamics of each flexibility layer. The findings reveal distinct behaviours in auction-based and continuous mechanisms, and offer insights into the Greek market’s real-time balancing capacity.
