Romania’s average day-ahead electricity price reached €176.14/MWh in September, up 81.49% year on year. The monthly average increased by 16.53% compared with August, when it stood at €151.16/MWh. Higher wholesale prices contributed to a sharp increase in the value of transactions on OPCOM.
Day-ahead market volumes and transaction values
Day-ahead trading volume totalled approximately 1.212 TWh, rising 4.5% year on year and 2.02% month on month. Average hourly traded volume was 1,683.9 MWh. Over the same period, the value of transactions climbed to €211.4 million, up 82.67% from September 2025 and 17.72% from August.
The increase in transaction value outpaced the change in volume, indicating that price movements were the main driver of market expenditure. For buyers relying on spot procurement, the reported figures correspond to substantially higher costs, with outcomes also depending on consumption profiles and existing hedges.
Intraday trading prices and volumes
Intraday trading reached 138.4 GWh, down 1.97% year on year but up 14.83% from August. The average intraday price was €169.88/MWh, increasing 84.06% year on year and 38.64% month on month.
The September data indicate that higher electricity costs extended beyond the day-ahead auction, affecting the expense of adjusting positions closer to delivery.
