多瑙河水位跌至历史低点，中欧和东欧多个国家的能源供应陷入危境。在布达佩斯，多瑙河水位周一降至约10厘米，远低于2018年历史低位33厘米 [1]。这一极端低水位直接威胁到依赖河流冷却的核电站和水电站的正常运营。
匈牙利帕克斯核电站受冲击最为严重，其发电量从通常的2000兆瓦急剧下降至周一的240兆瓦 [1]。由于帕克斯核电站贡献了匈牙利近50%的电力产量，约占全国电力消费的三分之一，这一下降幅度对国家能源供应构成重大挑战 [1]。为应对电力紧张局面，匈牙利政府采取了一系列应急措施，包括禁止电力货运列车在午间5至10点运行，以此实现每天70至90兆瓦时的节电目标 [1]。
邻国同样面临严峻形势。塞尔维亚关键水电站目前仅以20%产能运行 [1]，而罗马尼亚多瑙河水流量降至每秒1500立方米，不足7月平均水平的三分之一 [1]。罗马尼亚当局随后关闭了切尔纳沃达电站的一个反应堆，导致该工厂仅能维持半产能运行 [1]。气象预报显示，未来数周内无明显降雨预期，同时酷热浪将继续袭击该地区，日高温超过38摄氏度 [1]，这意味着能源紧张的局面在短期内难以缓解。
The Danube River has fallen to historic lows, forcing several Central and Eastern European nations to implement emergency measures to avert power shortages. Water levels in Budapest dropped to approximately 10 centimeters on Monday, far below the previous record low of 33 centimeters recorded in 2018 [1].
The crisis is severely impacting the region's nuclear and hydroelectric power generation. Hungary's Paks Nuclear Power Station, which typically generates 2,000 megawatts, has slashed output to just 240 megawatts due to insufficient cooling water [1]. The facility normally accounts for nearly 50 percent of Hungary's electricity production and roughly one-third of national power consumption [1]. In response, the Hungarian government has banned freight trains carrying electricity from operating between noon and 10 p.m., a measure expected to save 70 to 90 megawatt-hours daily [1], with cumulative power demand reductions reaching 700 megawatts [1].
Neighboring countries face similar challenges. Serbia's critical hydroelectric facilities are operating at just 20 percent capacity [1], while Romania's Danube water flow has plummeted to 1,500 cubic meters per second, less than one-third of July's average [1]. Romania has shut down one reactor at its Cernavoda power station, reducing the facility to half-capacity operations [1]. The outlook remains bleak, with forecasts predicting no significant rainfall in the coming weeks alongside an intensifying heat wave, with daily temperatures exceeding 38 degrees Celsius [1].
