Record Heatwave Disrupts Energy and Transport Across Europe

Central and Eastern Europe have experienced record breaking temperatures as a severe heatwave disrupts energy and transport systems. Slovakia recorded a high of 42.2 degrees Celsius in Dolne Plachtince, while Austria reached an all time high of 41.2 degrees Celsius in Bad Deutsch-Altenburg. Hungary also saw record overnight temperatures in Budapest, where levels fell only to 28 degrees Celsius. In Italy, authorities placed all 27 major cities on the highest heat alert for the first time this year, warning citizens to avoid direct sunlight between 11 am and 6 pm. At least four people are believed to have died in Italy during the heat.

Critical infrastructure has faced significant strain due to the heat and accompanying droughts. In Slovakia, the only nuclear power plant operated at 80 percent capacity as the Danube river fell to record lows. Hungary's only nuclear power plant was reduced to 10 percent capacity, though Prime Minister Péter Magyar later stated that one turbine was back online as water levels rose slightly. In Poland, authorities shut down the Kozienice and Połaniec coal fired power plants because low water levels in the Vistula River limited cooling supplies, removing 1.3 gigawatts of capacity from the system. In Germany, declining water levels forced some companies to move cargo by road instead of ship, leading to price increases.

Environmental impacts include accelerated melting of Alpine glaciers and widespread wildfires. Approximately half a million hectares have burned across the EU, primarily in Spain and France, with an additional 292,000 hectares burned in Ukraine. In Greece, strong wind gusts sparked wildfires that damaged a palm forest on Crete. Forecasts indicate another pulse of heat will affect France, Spain, and Italy early next week, moving toward Germany, Poland, and Czechia by the end of the week.
