Hungary Halts Only Nuclear Plant Amid Record Low Danube Levels Hungary has temporarily shut down its sole nuclear power plant, Paks, due to critically low water levels in the Danube River, marking the first such action since the 1980s. The decision comes as the country faces an unprecedented energy crisis driven by extreme heat and drought, which has drastically reduced the availability of cooling water essential for nuclear reactor operations. The move highlights the growing vulnerability of energy systems reliant on rivers for cooling, particularly in a warming climate. Paks, located approximately 100 kilometers south of Budapest, normally contributes nearly half of Hungary’s electricity supply and about a third of its overall consumption. With the Danube’s water levels dropping to historic lows, the plant can only operate at around 12 percent of its usual capacity. Officials warned that if the water continues to recede, the entire facility could be forced to shut down. This would exacerbate existing challenges, as Hungary already struggles with an outdated energy mix dominated by nuclear power, lacking sufficient renewable alternatives such as wind or solar, and possessing limited storage capabilities. The government has called on both industries and private households to reduce electricity usage, particularly during peak hours between 17 and 22. Large industrial consumers, including automotive giants Mercedes-Benz and BMW, have responded by implementing temporary production cuts. In Kecskemét, Mercedes has already scheduled a three-week production pause, while other firms are expected to follow suit. The Ministry of Energy has also ordered the suspension of electric-powered freight trains during peak times to ease pressure on the grid. Premier Peter Magyar emphasized that the crisis is worsening as the summer progresses, with temperatures in Budapest reaching up to 43 degrees Celsius. He acknowledged the need for immediate collective action, stating that “every drop of water counts” and urging citizens to conserve both electricity and water. Despite these efforts, Magyar admitted that the situation remains precarious, warning that power shortages could become widespread within days. The impact of the crisis extends beyond Hungary. In Romania, the Cernavoda nuclear plant, which provides about one-fifth of the country’s electricity, has also been affected. To address the issue, Romanian authorities used military forces to blast a rock formation along the Danube, aiming to increase water flow to the plant. While the operation was hailed as successful, officials warned that if the plan fails, the plant may have to be fully shut down by Thursday. Similar measures have been taken in Serbia, where the Iron Gate hydroelectric plant operates at just 20 percent of its capacity due to low water levels. The broader implications of the crisis underscore the fragility of energy systems dependent on river-based cooling. In Germany, the Rhine River has also reached record low levels, complicating transportation and power generation. Experts warn that such scenarios are becoming increasingly common due to climate change, emphasizing the urgent need for diversification in energy sources and improved resilience against extreme weather events. For Hungary, the crisis has exposed deep structural weaknesses in its energy policy. Under former Prime Minister Viktor Orbán, the country expanded solar power but blocked wind energy projects, leaving it heavily reliant on nuclear power. Orbán even proposed expanding Paks from four to six reactors, increasing dependency on Russian-supplied fuel. Now, with the plant nearing full shutdown, the government faces mounting pressure to rethink its approach to energy security and sustainability. As the situation unfolds, Hungary’s new administration under Magyar must navigate a complex landscape of economic, environmental, and political challenges. The country’s ability to manage the crisis will depend on how effectively it can balance short-term conservation efforts with long-term investments in renewable energy and grid modernization. Meanwhile, the broader European region watches closely, recognizing that the current crisis may serve as a harbinger of future energy challenges across the continent.
