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% from August, when it stood at €151.16/MWh. Higher wholesale prices lifted the value of transactions on OPCOM.
OPCOM day-ahead volumes and transaction values
Day-ahead trading volume reached 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. The value of transactions climbed to €211.4 million, up 82.67% from September 2025 and 17.72% from August.
The change in transaction value outpaced the increase in volume, indicating that price movements were the main driver of market expenditure changes. For buyers exposed to spot procurement, the data indicate higher costs, with outcomes varying by consumption profiles and existing hedges.
Intraday trading follows higher price levels
Intraday trading totaled 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 figures show that higher electricity costs extended beyond the day-ahead auction, affecting the expense of adjusting positions closer to delivery.
