Romania, Bulgaria and Serbia are also grappling with the effects of a series of prolonged heatwaves and low rainfall.

The level of the water of the Danube is so low that the nuclear power plant's suction nozzles cannot reach it Hungary's only nuclear power plant will be forced to shut down entirely for the first time due to record low water levels of the River Danube, Prime Minister Péter Magyar has said. The Soviet-era Paks power plant uses the Danube for cooling but the water level is so low that the suction nozzles cannot reach it. Magyar warned Hungary's energy supply could become "critical" from Monday due to the Paks shutdown and the ongoing heatwave, which will see temperatures hover around 37C for a week. Like much of Europe, Hungary has seen very low rainfall and high temperatures for much of the summer. The waters of the Danube have fallen to the lowest levels for 30 years in several countries, including neighbouring Serbia and Romania. Magyar asked Hungarians to limit activities that required significant energy consumption between the peak times of 17:00 and 22:00, including charging electric cars and using air conditioning equipment. A "rotational shutdown regime" was also possible if the other combined efforts were not enough to maintain the balance of the national grid, Magyar said, adding the government would compile a list of electricity and water consumers whose consumption could be limited.
