Europe's shrinking river systems reduce power production, transport and company profits

The record low water levels of Europe's rivers have hampered the transportation of goods and reduced electricity production. This has led to fears of the impact of the searing heat and unpredictable rainfall on the economy. Europe is experiencing the fastest warming of any continent, and heatwaves that have broken records. The drought has highlighted a need to reconsider how business practices are conducted.

Waterways are becoming less reliable for transporting goods like grains and oil or producing electricity, which is needed by millions of people to cool their homes.

The current dynamic means that either we will see blackouts, or we must invest more.

HYDROPOWER OUTPUT AND NUCLEAR POWER CUT Production of hydropower and nuclear power has fallen in Serbia and Hungary due to record low water levels along the Danube. The Danube passes through major cities such as Vienna, Budapest, and Belgrade, on its route from Germany towards the Black Sea.

Paks, the nuclear power plant that generates almost half of Hungary's electricty, is expected to be shut down Monday and possibly for several weeks, because the water level in the river which provides cooling water for the facility will remain too low to allow it to function safely.

Davor Maljokovic, production director at Djerdap 1, Serbia’s largest hydropower plant, said that output had fallen to just 20% of its capacity. The once wide shipping channel next to it has now shrunk, exposing sandbanks, gravel bars, and other debris.

Serbia's EPS state power utility reported that the lack of water also affected cooling systems at Serbia's coal-fired Kostolac power plants. This forced them to reduce output.

Both Serbia and Hungary claim they will compensate for their losses by importing electricity. This is a costly solution when the demand on the local?markets is high. The state-owned nuclear power company Nuclearelectrica in Romania also shut down one of its reactors this week due to the same reasons. A second reactor is expected to follow soon, depriving Romania of up to a fifth its electricity requirements. France also reduced nuclear power production due to low water levels and rising river temperatures.

TRANSPORTATION IS ALSO DRUNK BY HIGH WATER LEVELS

The energy industry is not the sole loser.

Cezar Gheorghe, consultant AGRIColumn in Romanian grain markets, told farmers on the Danube that they were having difficulty shipping their crops due to low water levels.

Only the ports that are closest to the Black Sea remain operational. Gheorghe stated that barges cannot pass through other ports.

"Crops purchasers could offer lower prices to farmers and load them into trucks. However, there may also be a lack of trucks."

A port spokesperson said that the amount of cargo being transported from and to Rotterdam, Europe's biggest sea port, to the Rhine is about 10% less than usual. This has been happening every?week, since the start of July.

The draught of chemical and oil product tankers, and dry bulk carriers is usually greater than that of container barges. This means they are positioned deeper in the water.

The drought has reduced company earnings. Apart from the devastation caused by wildfires, and the temperatures that have led to thousands of deaths in excess, the balance sheets of companies have suffered due to the changing climate.

Austrian utility Verbund said that drought conditions reduced earnings in the first half of this year by EUR370 million compared to a year with normal hydrological conditions. French utility EDF announced on Friday that earnings for the full year before interest, taxes, depreciation, and amortisation in 2026 would be down 10% due to low market prices, and heatwaves reducing power output.

The Po River basin in Italy has reached a high level of water scarcity. This is threatening the rice crops and water supply for drinking throughout the north. Renato Mazzoncini is the Chief Executive Officer of A2A regional utility. He expects hydropower production to be 3.9 TWh this year, compared with a historical average.

He said that "some of our reservoirs were under pressure." "We need to do a rain dance," he said. (Additional reporting by Inti landauro, Brussels; Giancarlo Navach, Milan; Danny Callaghan, Gdansk; Marleen Kasselbier, Zurich; Rene Wagner, Berlin; Writing and editing by Edward McAllister)
