Pursuant to the Harmonised Maximum and Minimum Clearing Prices (HMMCP) Methodology, established in accordance with Article 41(1) of Commission Regulation (EU) 2015/1222 of 24th July 2015 (CACM Regulation), the harmonised minimum clearing price for Single Day-Ahead Coupling (SDAC) shall be decreased by 100 EUR/MWh if the clearing price falls below a value of 70 percent of the harmonised minimum clearing price for SDAC in at least two market time units in an individual bidding zone or multiple bidding zones and in at least two different days within 30 rolling days from the first low price detection.
This condition was initially met by the clearing price level reached on 25th April 2026, for delivery date 26th April 2026, and subsequently again on 30th April 2026, for delivery date 1st May 2026, in several European countries and market time units. As a consequence, the current harmonised minimum clearing price for SDAC, equal to -500 EUR/MWh, will be lowered to -600 EUR/MWh. The new minimum clearing price shall apply in all bidding zones that participate in SDAC, from four weeks after the day the second event referred to has taken place. In this case, therefore, it will apply from the 28th May 2026, the first trading session, for the delivery date 29th May 2026.
During the transition period and until the new harmonized minimum clearing price for SDAC enters into force, any possible new detection events on minimum clearing prices that may occur will remain without consequences.

About SDAC
SDAC allocates scarce cross-border transmission capacity in the most efficient way by coupling wholesale electricity markets from different regions through a common algorithm, simultaneously taking into account cross-border transmission constraints, thereby maximizing social welfare. The aim of SDAC is to create a single pan European cross zonal day-ahead electricity market. An integrated day-ahead market increases the overall efficiency of trading by promoting effective competition, increasing liquidity, and enabling a more efficient utilization of generation resources across Europe.
