Danube Drought Forces Historic Shutdown of Hungary’s Paks Nuclear Plant as Europe Grapples with Energy Crisis

Budapest — For the first time in its 44-year history, Hungary’s Paks nuclear power plant has been completely taken offline, marking a stark escalation in the nation’s struggle against a relentless heatwave and historically low river levels. Prime Minister Péter Magyar announced late Saturday that the final reactor block was shut down overnight, leaving the country without its primary baseload power source as the Danube’s cooling waters dwindle to a fraction of their summer average. The Paks facility, located approximately 100 kilometers south of Budapest, relies heavily on the Danube to cool its four reactor blocks. With water levels in the river’s lower reaches plunging to just one-third of typical July averages, operators were forced to make the unprecedented decision to halt operations entirely. The move signals the beginning of what officials warn could be a weeks-long energy crunch, coinciding with soaring electricity demand from households and public services battling the persistent summer heat. In response to the looming deficit, the Hungarian government has deployed emergency reserves and negotiated emergency electricity imports. However, Magyar issued a stark decree warning that large industrial consumers face mandatory power cuts unless they voluntarily slash their usage. “If expected reductions are not implemented, we will be forced to disconnect major industrial facilities,” the Prime Minister stated. By Monday, the grid is expected to lose up to 2,000 megawatts of capacity, creating a severe supply-demand imbalance that could strain the already stagnating national economy. Hungary’s energy emergency is part of a broader continental crisis. Downstream neighbor Romania recently declared a nationwide state of emergency through August after a dramatic collapse in power generation. Romanian leadership confirmed the shutdown of one reactor at the Cernavoda nuclear plant and is actively coordinating evening-peak imports from Ukraine, Greece, and Bulgaria. France has similarly been forced to curtail nuclear output amid prolonged drought and record temperatures, underscoring how climate-driven hydrological shifts are destabilizing Europe’s traditional energy pillars. The domestic economic ripple effects are already visible. Major industrial players, including automakers Mercedes-Benz and Suzuki, have confirmed they will implement aggressive electricity-saving measures at their Hungarian facilities. Mercedes-Benz had already scheduled a three-week production pause at its new Kecskemét plant, but the shutdown of Paks will further disrupt output and supply chain logistics. Government officials are now weighing whether to mandate industrial conservation or rely on voluntary cuts, with a final decision expected within hours. Beyond the energy sector, the drought is inflicting widespread damage across Hungary. The water authority projects that Danube levels will continue to decline in the coming days, exacerbating restrictions on river shipping and tourism. More than 100 towns and villages have already been placed under strict water rationing, highlighting the compounding humanitarian and ecological toll of the dry spell. As heat forecasts remain unchanged and reservoir levels stay critically low, Hungarian authorities are bracing for a prolonged period of managed scarcity. The complete shutdown of Paks serves as a sobering reminder of how interconnected modern energy infrastructure remains with natural water cycles—and how quickly climate extremes can test the resilience of even the most established power grids. For now, Budapest’s strategy hinges on conservation, cross-border cooperation, and hoping the skies finally break the drought before the summer’s end. Related Sources: • Source 1 • Source 2
