Record Low Danube Levels Trigger Regional Energy Emergency
8/4/2026, 6:10:04 AM
Background: Drought and Heat Wave
A prolonged drought and successive extreme-heat waves have dramatically lowered the Danube River, one of Europe’s largest waterways. In Hungary’s capital, Budapest, water depth fell to roughly 10 cm, far below the previous record low of 33 cm set in 2018. Similar declines were reported downstream, with flow in Romania dropping to about 1,500 cubic meters per second—less than one-third of the typical July average.
Measures Taken by Affected Countries
Hungarian Prime Minister Péter Magyar announced that engineers kept the final turbine at the Paks nuclear plant running, averting an immediate shutdown. The government first asked major industrial users to curb electricity use and later issued a decree allowing mandatory reductions for large consumers. Magyar reported that the conservation push cut demand by roughly 700 megawatts in a single day.
In Romania, the military detonated 180 kilograms of explosives near the Bala Canal to redirect water toward the Cernavoda nuclear plant’s cooling system. Acting Prime Minister Ilie Bolojan declared a nationwide energy-sector alert and urged citizens to limit electricity use during peak evening hours. He noted that carmakers Dacia and Ford had placed production on hold until mid-August and that other firms had agreed to reduce peak-hour consumption.
Serbian Prime Minister Djuro Macut convened an emergency meeting after the Danube’s low level reduced the country’s key hydroelectric plant to about 20 % of its capacity. He appealed to residents to minimize the use of high-consumption appliances such as air conditioners, describing the situation as “serious and demanding.”
Impact on Power Generation and Other Sectors
The Paks plant, which normally supplies nearly half of Hungary’s electricity, was operating at only 240 megawatts—about one-tenth of its typical output. Romania’s Cernavoda plant shut down one reactor unit and ran the remaining unit at roughly half capacity. Serbia’s hydro plant’s output fell to one-fifth of normal levels. The low water also disrupted shipping and agricultural activities along the river.
Outlook and Ongoing Conservation Efforts
Both Hungary and Romania have introduced restrictions on electric freight trains during peak hours, estimating a daily saving of 70–90 megawatt-hours. Authorities continue to monitor river levels, but forecasts indicate no significant rainfall in the coming weeks, leaving the region reliant on mandatory conservation measures and emergency management to avoid further power-plant shutdowns.
