匈牙利总理佩特尔·马杰宣布，该国唯一的帕克斯核电站将首次完全关闭[1]。这一决定源于多瑙河水位创30年新低，河水无法到达核电站的冷却水吸水嘴[1]。罗马尼亚也被迫采取类似措施，关闭切尔纳沃达核电站706兆瓦反应堆[1]，该反应堆提供罗马尼亚约20%的电力[1]。
多瑙河流量大幅下降。根据罗马尼亚国家水文学研究所数据，多瑙河平均流量从7月的4700立方米/秒下滑至周三的1600立方米/秒[1]。马杰警告能源供应从周一起可能变得"关键"，同时匈牙利正经历37摄氏度的高温[1]。为应对电力短缺，匈牙利政府要求民众在17:00至22:00高峰时段限制用电，避免充电和使用空调[1]。政府同时警告，若这些措施不足以缓解电力压力，将启动轮转关闭制度[1]。
Hungarian Prime Minister Peter Szijjarto announced that the country's sole nuclear facility, the Paks power plant, will undergo its first complete shutdown due to critically low water levels in the Danube River, which have prevented cooling water from reaching the plant's intake [1]. The Danube has fallen to its lowest level in 30 years across Hungary, Serbia, and Romania, with flow rates plummeting from 4,700 cubic meters per second in July to 1,600 cubic meters per second by Wednesday, according to Romania's National Institute of Hydrology [1].
The energy crisis extends beyond Hungary's borders, as Romania has been forced to shut down one reactor at its Cernavoda nuclear station, which normally supplies approximately 20 percent of the country's electricity [1]. In response to the emergency, Hungarian authorities have called on citizens to limit electricity consumption between 5 p.m. and 10 p.m., urging them to avoid charging devices and using air conditioning during peak hours [1]. Prime Minister Szijjarto warned that energy supplies could become "critical" beginning Monday, amid a heat wave pushing temperatures to 37 degrees Celsius across the country [1]. Should conservation measures prove insufficient, officials have cautioned that rolling blackouts may be implemented [1].
