Generation mix

Romania’s electricity mix became increasingly constrained after 2023, as declining hydropower outweighed solar generation and nuclear output.

Electricity generation by fuel type · GWh, 2022–2025

Fig. 2.1
Source: to be confirmed by CIGATotals shown above bars
  • Falling hydropower generation accounted for most of the nearly 8 TWh decline in total electricity production since 2023.
  • Stable nuclear generation cushioned the impact of weaker hydro conditions, maintaining around one-fifth of total electricity supply.
  • Growing solar PV partially compensated for lower hydro output, but its scale remained insufficient to offset losses.
  • Coal generation continued its downward trajectory, indicating gradual progress towards a lower-carbon electricity mix despite lower overall generation.

Installed capacity

Romania’s installed capacity reached a record 19.4 GW in 2025, driven by rapid solar expansion despite continued coal retirements.

Installed power generation capacity by technology · MW, 2022–2025

  • Total installed capacity increased by nearly 1.2 GW since 2023, reflecting sustained investment in new generation assets.
  • Solar PV capacity expanded by almost 1 GW between 2022 and 2025, becoming Romania’s fastest-growing generation technology.
  • Coal capacity declined by approximately 1.5 GW, accelerating the transition away from carbon-intensive electricity generation.
  • Hydro, nuclear and natural gas capacities remained broadly stable, providing system flexibility and security during the energy transition.

EU comparison

Romania maintains one of the EU’s most diversified electricity mixes, reducing reliance on any single generation technology.

Electricity mix by EU country · share of generation, 2025

Fig. 2.3
Source: OWID, EMBER
  • Low-carbon sources provide around 65% of Romania’s electricity, led by hydro, nuclear and wind.
  • Natural gas and coal together still account for roughly one-third of electricity generation, highlighting remaining decarbonisation challenges.
  • Romania’s electricity mix is more balanced than many EU peers, avoiding excessive dependence on either nuclear or fossil fuels.
  • Solar contributes a relatively modest share compared with southern European countries, indicating significant untapped expansion potential.

  • Day-ahead market prices are projected to decline nearly 40%, from around €118/MWh to €74/MWh by 2050.
  • Balancing market prices remain increasingly volatile, with surplus prices falling to around 0.5× 2025 levels by 2050.
  • Inflation is forecast to increase by approximately 65% by 2050, outpacing electricity price growth over the period.
  • The widening gap between deficit and surplus balancing prices signals stronger incentives for flexibility and energy storage investments.

  • aFRR reservation fees are projected to halve by 2030, stabilising near €7/MWh thereafter.
  • mFRR reservation fees decline steadily, reducing ancillary service procurement costs by roughly 50% over the forecast period.
  • aFRR bid prices fall from approximately €180/MWh to €65/MWh, reflecting lower balancing costs.
  • mFRR bid prices nearly triple to around €100/MWh, indicating growing value for slower balancing services by 2050.

  • Monthly wholesale prices declined from nearly €160/MWh in February to below €90/MWh by late spring 2025.
  • Evening price peaks consistently exceeded €850/MWh, highlighting persistent ramping needs during high-demand hours.
  • Compared with 2025, early-2026 prices shifted towards earlier evening peaks, reflecting changing demand and renewable generation patterns.
  • Wholesale prices recovered above €120/MWh during autumn 2025, underlining the strong seasonal influence on electricity markets.

Cross-border trade

Romania has shifted from a long-standing net electricity exporter to a structurally import-dependent market in recent years.

  • Net electricity imports reached approximately 4.5 TWh in 2025, the highest level in over three decades.
  • Romania remained a net exporter for most of 1999–2019, with exports peaking near 7 TWh in 2014.
  • The transition to net imports after 2020 reflects tightening domestic supply amid changing generation patterns.
  • Import dependency has increased markedly since 2023, highlighting growing reliance on regional electricity markets for security of supply.
