Romania shuts its only nuclear power plant following severe drop in Danube levels

What happened
Romania has shut down the Cernavodă nuclear power plant, its sole nuclear facility, after extreme heat caused a major drop in the water level of the Danube River. The facility generates 20% of the country's electricity supply. The plant is not expected to restart for at least 10 days while river levels remain critically low.
Why it matters
Losing one-fifth of national electricity generation during summer demand spikes puts immediate pressure on the grid. Romanian energy authorities must rely on alternative domestic power generation or imported electricity to balance the grid, highlighting how hydrological disruptions can suddenly strain national power networks.
Bigger picture
The shutdown underscores the operational vulnerability of base-load energy infrastructure to extreme climate events. Nuclear and thermal plants reliant on major rivers for cooling face growing supply risks during severe heatwaves and droughts, raising broader security concerns for interconnected European power markets.
Watch next
Monitor official Danube River water level reports over the coming 10 days, energy import updates from Romanian grid operators, and confirmation of a restart schedule for the Cernavodă facility.
