South-East European day-ahead prices stayed elevated on Friday, with a sharp split between the higher-priced Central European and Italian corridor and the lower-priced Serbian zone. The regional benchmark HUPX settled at €123.26/MWh, almost unchanged from the previous day. Slovenia reached €125.40/MWh, while Croatia traded at €119.61/MWh and Romania at €116.24/MWh. Bulgaria and Greece converged at €115.64/MWh, and Italy remained the most expensive market at €148.43/MWh.
Serbia was the clear regional discount at €106.01/MWh. That left SEEPEX around €17.25/MWh below HUPX and more than €42/MWh below Italy. The gap reflected the strongest intraday swings in the Serbian market, where SEEPEX fell to €20/MWh at hour 14 before rising to €208.10/MWh at hour 21. The near-€188/MWh intraday spread corresponded with midday solar surpluses and evening scarcity after photovoltaic output falls.
Demand, generation mix and cross-border flows
Regional electricity demand increased slightly to 31,291 MW. Net imports declined to 658 MW, down from 899 MW a day earlier. Total generation remained close to 30.6 GW. Wind output rose by about 584 MW to 1,771 MW, partly offsetting a 520 MW fall in hydro generation to 4,871 MW.
Solar stayed strong at 6,302 MW, while other generation components included coal at 6,348 MW, gas at 4,521 MW, and nuclear at 5,579 MW. The changes in wind and hydro were reflected alongside the solar pattern that shaped intraday price moves in Serbia. Net import levels also shifted across the region compared with the prior day.
