Heavy storms flood streets, kill one in west Germany

Thunderstorms across western Germany on Wednesday night left one woman dead, as well as streets and basements flooded, while lightning strikes started fires in other places.

One 51-year-old woman in Dortmund died during the storms when a tree fell over onto her. Police believe that the tree was knocked over by the wind and rain amid the thunderstorm.

In Cologne, firefighters were called to around 550 operations alone. Streets and basements there flooded, and air as well as train travel was delayed.

Numerous cars on the streets were also left partially submerged in water, and one underground garage had water measuring 1.5 metres high.

Water also covered the floor in parts of the central train station, as pictured below.

Flights at Cologne Bonn airport were interrupted for 90 minutes due to the weather, with 15 taking off late and 14 flights arriving late. One flight to Munich was also cancelled. After a tree fell onto overhead wiring for a train line going from Bonn to Koblenz, some train journeys were cancelled and others were delayed.

One of Germany’s four biggest folk festivals, Düsseldorf’s Rheinkirmes, was interrupted for about two hours due to the storms. But by 5.45pm, it had resumed.

Meanwhile in Baden-Württemberg, the Hohentwielfestival music festival with 3,200 visitors ended prematurely as the guests were told to leave due to the heavy wind and rain.

Elsewhere in Lower Saxony, lightning strikes sparked several fires on agricultural land, which firefighters had to put out overnight. No one was injured, according to police.

The German Weather Service (DWD) predicts the stormy weather will continue into Thursday, with rain or thunderstorms expected to fall in nearly every part of the country by the end of the day.

By Friday morning, the rain clouds are expected to be cleared away, says DWD, though the southwest of the country around Stuttgart and Konstanz are forecast to be hit by more thunderstorms on Friday evening.

Saturday is predicted to be rainy and stormy across most of the country again, though as of Thursday, DWD predicts the area around Munich to be virtually the only dry spot at the start of the weekend. This won’t last, however: the Bavarian capital will join the rest of Germany in having a very wet Sunday.


Why sunny weather in Germany can switch off solar panels

The more the sun shines in the southern German town of Aurach, the more likely it is that Jens Husemann's solar panels will be disconnected from the grid -- an exasperating paradox at a time when Germany is navigating an energy supply crisis.

Why sunny weather in Germany can switch off solar panels

“It’s being switched off every day,” Husemann told AFP during a recent sunny spell, saying there had been more than 120 days of forced shutdowns so far this year.

Husemann, who runs an energy conversion business near Munich, also owns a sprawling solar power system on the flat roof of a transport company in Aurach, Bavaria.

The energy generated flows into power lines run by grid operator N-Ergie, which then distributes it on the network.

But in sunny weather, the power lines are becoming overloaded — leading the grid operator to cut off supply from the solar panels.

“It’s a betrayal of the population,” said Husemann, pointing to soaring electricity prices and a continued push to install more solar panels across Germany.

Europe’s biggest economy is eyeing an ambitious switch to renewables making up 80 percent of its electricity from 2030 in a bid to go carbon neutral.

But Russia’s invasion of Ukraine has put a spanner in the works.

Moscow has cut gas supplies to Germany by 80 percent, in what is believed to be a bid to weaken the European powerhouse’s resolve in backing Ukraine.

As a result, Berlin has been scrambling for alternative sources across the world to replace the shortfall.

This makes it all the more frustrating for Husemann, whose solar panels normally generate enough electricity for 50 households. With the repeated shutdowns, he suspects they will only supply half of their capacity by the end
of the year.

Grid bottlenecks

Grid operator N-Ergie, which is responsible for harvesting electricity from Husemann’s panels, admits the situation is less than ideal.

There were 257 days last year when it had to cut off supply from solar panels on parts of the grid.

“We are currently witnessing — and this is a good thing — an unprecedented boom in photovoltaic parks,” Rainer Kleedoerfer, head of N-Ergie’s development department, told AFP.

But while it takes just a couple of years to commission a solar power plant, updating the necessary infrastructure takes between five and 10 years, he said.

“The number of interventions and the amount of curtailed energy have increased continuously in recent years” as a result, according to N-Ergie spokesman Michael Enderlein.

“The likelihood is that grid bottlenecks will actually increase in the coming years,” while resolving them will take several more years, Enderlein said.

According to Carsten Koenig, managing director of the German Solar Industry Association, the problem is not unique to solar power and also affects wind energy.

Solar bottlenecks tend to be regional and temporary, he said. “Occasionally, however, we hear that especially in rural areas in Bavaria, the shutdowns are more frequent.”

2.4 million households

Koenig agrees the problem is likely to get worse before it gets better.

“This will be especially true if political measures aimed at sufficiently expanding the power grid in Germany… drag on for too long,” he said.

Some 6.1 terawatt hours of electricity from renewables had to be curtailed in 2020, according to the most recent figures available.

With an average consumption of around 2,500 kilowatt hours per year in a two-person household, this would have been enough to power around 2.4 million households.

A spokesman for Germany’s Federal Network Agency said it did not share the belief that “it will not be possible to expand the network in line with demand in the coming years”.

Only some aspects of the expansion are seeing delays, the spokesman said — mainly due to slow approval procedures and a lack of specialist companies to do the work.

According to Husemann there have also been delays to the payments he is supposed to receive in return for the solar power he supplies — or cannot supply.

He said he is already owed around 35,000 euros ($35,600) for electricity produced so far this year that has never found its way into a socket.
