      Clean Energy Package switch to quarter-hour trading in the day-ahead auction

      The introduction of 15-minute trading on all day-ahead electricity markets of the EU, originally announced for June, is now imminent:

      • In the electricity markets connected through the cross-border Single Day-Ahead Coupling (SDAC), the Market Time Unit (MTU) will be reduced from 60 minutes to 15 minutes starting with the day-ahead auction on September 30, 2025 (delivery day: October 1, 2025).
      • The affected electricity markets are:
        • Central Europe: Belgium, Germany, France, Luxembourg, Netherlands, Austria.
        • Southern Europe: Italy, Portugal and Spain.
        • Eastern Europe: Estonia, Latvia, Lithuania, Poland, Slovakia and Czech Republic.
        • Southeastern Europe: Bulgaria, Greece, Croatia, Romania, Slovenia and Hungary.
        • Northern Europe: Finland, Denmark, Norway and Sweden.
      • The publication of the day-ahead auction results will also take place in 15-minute resolution from the delivery day October 1, 2025.
        • A 60-minute price index will also be published as the arithmetic mean of the corresponding 15-minute prices. (Info from EPEX SPOT)

       

      We at Montel Risk (formerly price[it]) will respond to this development accordingly and change the resolution of our power PFCs for all affected markets from 60 minutes to 15 minutes:

      • If you still require PFCs in hourly resolution, we will continue to provide you with PFCs in the usual way beyond October 1.
        • This is our standard option: if we do not hear back from you, the PFCs will continue to be delivered to you in the usual resolution, path, name and format.
      • Otherwise, you can obtain quarter-hourly PFCs from us no later than this date.
      • In the absence of real quarter-hourly spots on which we could train our models, we will initially create these curves based on our expectations:
        • The quarter-hourly IDA1 auction serving as a reference spot is subsequent to day-ahead trading in time, and traders use this market to better adjust the quantities purchased in the DA auction to their profiles.
          • Especially during increasing/decreasing solar ramps, this leads to the characteristic jagged patterns within the hours.
        • Quarter-hourly day-ahead trading is likely to be very beneficial for these traders, as volumes can be bought/sold much more precisely.
          • We therefore expect many traders to quickly adapt to quarter-hourly trading.
          • These new markets are therefore unlikely to display jagged patterns like the IDA1 markets, but rather smoother curves within a day.
        • For all the mentioned electricity markets we have already created quarter-hourly PFC products, which we can supply to you as part of our service.
          • You are welcome to test these products in parallel with your deliveries to prepare your processes for quarter-hourly PFCs.
        • If you would like to prepare the technical switch in advance, we also have the option to export and send you the HPFC in quarter-hourly resolution (content: hourly prices rolled out evenly over quarter-hours).
