Record-Low Danube Water Levels Threaten Energy Stability in Eastern Europe

Budapest: Governments in Central and Eastern Europe are implementing emergency measures to conserve electricity and prevent potential energy shortages as unprecedented low water levels on the Danube River disrupt power generation and jeopardize essential infrastructure. The ongoing drought and consecutive heatwaves have driven water levels along this vital river to historic lows, significantly impacting nuclear, hydroelectric, and other energy facilities reliant on the Danube.

In Budapest, the river’s water levels have plummeted to approximately 10 centimeters, far below the previous record low of 33 centimeters set in 2018. With no significant rainfall anticipated and temperatures projected to exceed 38°C in the coming days, authorities do not foresee a quick recovery in water levels.

Hungary’s Nuclear Plant Near Shutdown

The crisis has brought Hungary’s sole nuclear power station, the four-reactor Paks Nuclear Power Plant, to the verge of a complete shutdown for the first time in its 44-year history. This facility relies on Danube water for reactor cooling and was generating only 240 megawatts on Monday, a stark contrast to its usual output of around 2,000 megawatts.

Hungarian Prime Minister Péter Magyar indicated that engineers had managed to keep the plant’s last operational turbine running temporarily, postponing what was expected to be a full shutdown over the weekend. He noted, “This is very good news, because the complete shutdown of the Paks power plant can still be avoided, at least temporarily, on one of the biggest consumption days.”

Located about 90 kilometers south of Budapest, the Paks plant accounts for nearly half of Hungary’s electricity production and supplies about one-third of the national electricity consumption. To mitigate the reduced output, Hungary has ramped up electricity imports from neighboring countries and increased reliance on renewable energy sources.

The government has also urged major industrial users and households to lower power consumption, especially during peak demand hours from 5 p.m. to 10 p.m. Additional measures include restrictions on electric freight train operations during peak periods, which are expected to save between 70 and 90 megawatt-hours of electricity daily. A decree issued over the weekend allows authorities to enforce energy-saving measures for large industrial and commercial consumers if necessary. According to Magyar, the conservation campaign successfully reduced electricity demand by approximately 700 megawatts on Sunday.

Serbia and Romania Also Affected

The energy crisis extends beyond Hungary. In Serbia, record-low Danube levels have diminished output at the country’s primary hydroelectric facility to just 20% of its capacity. Prime Minister Djuro Macut convened an emergency meeting focused on national energy security, urging residents to limit the use of high-consumption appliances like air conditioners, describing the situation as “serious and demanding.”

Serbian President Aleksandar Vucic warned that water levels could soon drop too low for normal river transport operations. While cargo vessels are still navigating the Danube, they are currently operating with only half their usual loads.

Romania is facing similar challenges. Authorities reported that Danube water flow has decreased to approximately 1,500 cubic meters per second, less than one-third of the river’s average flow in July. As a precaution, officials have shut down one reactor unit at the Cernavoda Nuclear Power Plant, with additional output reductions planned. The facility is currently operating at roughly half of its normal capacity.

Growing Pressure from Heat and Drought

The combination of prolonged drought, extreme heat, and rising electricity demand is intensifying pressure on power systems across the region. As temperatures soar, the demand for cooling and water consumption continues to rise, while river-dependent energy production is being constrained.

Authorities in the affected countries are closely monitoring conditions, with further conservation measures likely if drought conditions persist and Danube water levels continue to decline.
