Electricity prices on Croatia’s CROPEX increased in September even though traded volumes were lower than in August. The exchange reported total traded electricity of 1.364 TWh, down 9.9% month on month but up 25% compared with September 2025.
Trading activity was split between the day-ahead and intraday markets. The day-ahead market accounted for 902.8 GWh, while intraday trading reached 461.1 GWh. Average daily day-ahead turnover was approximately 30.1 GWh.
Day-ahead and intraday pricing
The average day-ahead baseload price rose 14% to €172.80/MWh. The peak-load average increased 15.7% to €143.86/MWh. Peak-load electricity remained approximately €28.94/MWh cheaper than baseload.
On the intraday market, the average price was €175.40/MWh, slightly above the day-ahead baseload level. The figures show that price levels moved higher alongside a monthly decline in total traded volumes versus August.
CROPEX ownership and market timeline
CROPEX is jointly owned by transmission system operator HOPS and electricity market operator HROTE. Its day-ahead market started operating in 2016, followed by intraday trading in 2017.
Croatian-Slovenian border coupling was introduced in 2018, extending CROPEX market integration beyond national trading. September’s results also reflected higher exchange activity than in the same month of the previous year, alongside lower monthly turnover than in August.
