Publication of RDN market results on the TGE website - implementation of 15 MTU on RDN I fixing

Towarowa Giełda Energii informs that in connection with the implementation of 15-minute products in the RDN I fixing, the presentation of Day-Ahead Market market results on the TGE website under the Day-Ahead Market tab will change.

Details of the changes are as follows:

a. In the column “Fixing I” -> “Price [PLN/MWh]” prices will be displayed for both 15-minute instruments (official local auction results) and 60-minute instruments (calculated as the arithmetic mean of the prices from the four 15-minute intervals within a given hour).

b. In the column “Fixing I” -> “Volume [MW]” only values for 15-minute instruments will be displayed. These will be volumes resulting from orders executed across all time units (15, 30, and 60 minutes), aggregated to a 15-minute resolution.

c. The publication of data in the other columns, such as “Continuous quotes”, “Fixing II” and “Total trade” remains unchanged.

d. The structure of the RDN market results table on the TGE website will remain unchanged – only the contents of two columns will be modified.

The changes will take effect on June 10, 2026, which will be the first trading day (with delivery on June 11, 2026).
