A severe drought and heatwave have driven Danube water levels to record lows, forcing Hungary to completely shut down its Paks nuclear plant and Romania to shut one reactor at Cernavodă. Both countries declared emergencies, implementing energy conservation and water diversion measures. The crisis has also disrupted shipping, hydropower, and drinking water supplies, highlighting a broader European energy and water scarcity event.
- Hungary completely shut down its Paks nuclear plant, which supplies about 40% of the country's electricity, due to critically low Danube water levels and declared a state of emergency.
- Romania shut down one reactor at its Cernavodă nuclear plant and diverted canal water to address the cooling water shortage.
- Record-low Danube levels disrupted shipping, hydropower generation in Austria, and drinking water supplies along the river.
