Weather: Germany sees extreme heat and storms

An extreme heat warning was in place for eastern Germany on Monday, while storms were also set to hit the country.

The German Weather Service (DWD) said temperatures could reach 36C on Monday. 

In the morning, the DWD issued an extreme heat warning for eastern regions, as shown below in the map.

Forecasters said later on Monday, the south and east of the country would be hit by thunderstorms as well as large hailstones, strong winds and heavy rain.

In the north, west and centre of Germany, forecasters predicted clouds and some showers. Over the course of Monday, heavy thunderstorms with heavy rain, hailstones and strong winds are also possible in the north.

“Thunderstorms have occurred in the past few days and will continue in the coming days, as the established weather situation will remain virtually unchanged,” said a spokesperson from the DWD. 

However, the large temperature differences are striking: in the west of Germany, the mercury will only reach just above 20C in places.

Overnight to Tuesday, the DWD predicts thunderstorms – some of them heavy – from the Baltic Sea to the Alps, and later there is set to be more showers. It could still reach 28C in some places, especially in the east.

The DWD said: “The risk of thunderstorms will remain in the southern half of the country, while the northern half will calm down after the last thunderstorms have moved to Poland.

“This will change again on Wednesday night, when showers and thunderstorms, some of them thundery, as well as heavy rain will make their way north. On Wednesday, it will be quite unsettled with muggy temperatures almost all over the country.”

Forecasters said the weather will remain changeable for the rest of the week, but it should become more settled from next weekend.

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.
