Romania’s electricity consumption totalled 24.11 TWh from January to June, falling 3.3% year on year, according to the National Institute for Statistics. Industrial demand declined by 0.6% to 18.61 TWh. Household electricity use dropped 11.8% to 5.31 TWh, while power for public lighting decreased 4.6% to approximately 191.3 GWh.
Generation increases support supply-demand balance
Romanian electricity generation rose during the same period, increasing 5.2% to 26.23 TWh. The data show hydropower as the largest contributor to the increase, with output up 17.9% to 7.5 TWh. Solar generation, including prosumers, climbed 42.1% to 3.26 TWh, while wind generation increased by 9% to 3.27 TWh.
The higher renewable output offset declines in other segments of conventional generation. Thermal generation fell 5.9% to 7.68 TWh. Electricity production at the Cernavoda nuclear plant decreased by 11.7%, reaching 4.53 TWh.
Exports rise as imports fall in first half of 2026
Cross-border flows shifted alongside the stronger domestic generation environment. Romanian electricity exports increased by 11.4% to 7.69 TWh, while imports declined by 9.8% to 8.46 TWh. Romania remained a net importer over the six-month period.
The gap between imports and exports narrowed as renewable and hydro production strengthened during the first half of 2026 . Romania is described as one of southeast Europe’s largest electricity systems and a key transit market between Bulgaria, Hungary, Serbia, Ukraine and Moldova . The reported rise in Romanian renewable output can affect price formation and cross-border flows beyond the domestic market.
Primary energy output trends differ from electricity generation
The source reports primary-energy production moving differently from electricity generation figures. Total primary energy-resource production was recorded at 7,929.6 million tonnes of oil equivalent, down 2.6% year on year . Coal output fell by 17.9%, with production at 742.3 million tonnes of oil equivalent.
The report also shows oil production down 7.2% to 1,160.7 million tonnes of oil equivalent. Natural gas production decreased by 0.6%, reaching 3,710.3 million tonnes of oil equivalent. For the first half, electricity supply is described as increasingly supported by hydro, wind and particularly solar generation while underlying domestic electricity consumption remains below 2025 levels .
