中欧和东欧地区正面临创纪录的干旱和热浪，导致多瑙河水位跌至历史新低，对该地区电力系统造成严重冲击。[1]布达佩斯气温已达43摄氏度，[1]依赖该河冷却水的核电厂和水电站被迫大幅削减产量。[1]
匈牙利受影响最为严重。该国Paks核电厂目前仅以12%的产能运行，[1]而该厂通常占匈牙利总发电量的约50%，占全国用电需求的约三分之一。[1]罗马尼亚的Cernavoda核电厂也面临冲击，其一座700兆瓦反应堆上周已被迫停运。[1]其他国家的电力结构差异导致其易损性程度不同：斯洛伐克约60%的电力来自核电、20%来自水电，[1]奥地利约60%依赖水电，[1]塞尔维亚约65%的电力来自煤电、25%来自水电。[1]
保加利亚因拥有全球最大的电池储能设施而相对抗风险能力较强，该国电池储能容量为3.4吉瓦、储能容量为8.6吉瓦时，占其总装机容量的16%。[1]同时，多家大型制造企业已因电力限制而被迫减产。[1]
Record-breaking drought and extreme heat are severely straining electricity generation across Central and Eastern Europe, with the Danube River reaching historic low water levels that have forced major power plants to reduce operations.[1] Temperatures in Budapest have soared to 43 degrees Celsius (109.4 degrees Fahrenheit), intensifying the crisis.[1] The situation has become particularly acute for nations dependent on the river's cooling water for nuclear and hydroelectric facilities.
Hungary faces the most immediate challenge, with its Paks nuclear power plant currently operating at just 12 percent capacity.[1] This facility normally generates approximately 50 percent of Hungary's total electricity and supplies roughly one-third of the nation's power consumption.[1] In Romania, the Cernavoda nuclear plant was forced to shut down one of its 700-megawatt reactors last week.[1] Large manufacturing enterprises across the region have begun reducing production in response to power constraints.
The impact varies significantly across the affected nations due to differences in their energy portfolios. Serbia derives approximately 65 percent of its electricity from coal and 25 percent from hydropower, while Slovakia relies on nuclear power for about 60 percent of its supply and hydroelectricity for 20 percent.[1] Austria generates roughly 60 percent of its electricity from water sources.[1] Bulgaria appears relatively better positioned, owing to its substantial battery storage capacity of 3.4 gigawatts with a total storage capability of 8.6 gigawatt-hours, representing 16 percent of its total installed capacity.[1]
