Romania declares national energy alert for August as Danube drought threatens Cernavoda nuclear plant shutdown within days

Summary

Romania's government declared a national state of energy alert for the entire month of August on July 31 after the Danube River fell to historically unprecedented levels, threatening the Cernavoda Nuclear Power Plant's ability to draw cooling water. Prime Minister Ilie Bolojan said Romania risks losing 20% of national electricity production if the plant's second reactor stops, after Unit 1 was already shut down on July 28. Romania's water authority told Digi24 that the Danube near Cernavoda is dropping 2 to 3 centimetres per day and the plant can function at current limits for only another four to five days. The crisis runs in parallel with Hungary's Paks plant crisis, where output has already fallen to 25% of capacity, compressing regional nuclear electricity supply across Central Europe simultaneously.

The split

All three reports came from Digi24, Romania's main TV news channel, which is the dominant source in this feed on the Romania dimension of the Danube drought. No international English-language outlet covered the Romanian government's national alert declaration in this feed; the crisis is visible to Romanian readers but largely absent from the international English-language press as of August 2, creating a significant blind spot.

By the numbers

• 20%, electricity production Romania risks losing if Cernavoda Unit 2 also shuts down
• 4-5 days, window before Cernavoda cooling water intake becomes impossible at current Danube levels
• 2-3 cm per day, rate of Danube water level decline near Cernavoda
• All of August, duration of Romania's declared national energy alert

Why it matters

Romania's national alert declaration is a government-level crisis response, not just an operational precaution. If both Cernavoda units stop, Romania will need to import electricity or curtail industrial supply, at the same moment Hungary is managing the same situation at Paks, meaning the two countries cannot rely on each other for backup supply. The Danube drought simultaneously cutting nuclear output on both sides of the Romania-Hungary border is a stress on the regional grid not seen before.

What to watch

• Whether Cernavoda can maintain operation beyond the four-to-five day water-level window
• Romania's electricity import agreements and which countries can supply backup power
• The effectiveness of the planned barge-sinking remediation measure for cooling water intake
• Whether the Romanian national energy alert escalates to emergency rationing of industrial consumers
