Highs of 23C forecast for this weekend

A warmer weekend is set to chase Germany's cooler week away, with sunshine and highs of 23C forecast.

Low pressure has brought a few chilly, drizzly days to large stretches of the country, but a higher pressure system will move in by Saturday, according to state weather service DWD on Friday.

The latter half of Friday afternoon will be rainy for the north and eastern states, while in the west and south it will be clear and dry until sunset.

As night arrives the north will remain clouded over, but dry. The south will be patchy with a chance of fog and in the Alps there will likely be a light frost. Lows of 6C to 0C should be expected, making it chilly.

Saturday will see higher pressure pushing temperatures up to highs of 15C on the north coast and 21C inland. The whole country should see some sun with a very gentle breeze. But in the very far west it could still be a bit cloudy.

Clear skies will be the theme of Saturday night, which means that it will remain relatively cool with lows of 0C in rural areas and 7C in towns and cities. It could also be foggy, said the DWD.

Any fog from the night before will clear by Sunday morning, as really warm air will settle across Germany bringing highs of 23C in the west.

Everywhere else will be slightly cooler, but not by much. There will be a light, easterly breeze.

Sunday night will not only be an hour shorter due to the clocks going forward, but also continue to be clear and dry.

Only the very north east will see a few clouds gathering. Lows will be the same as the night before, ranging from 0C to 7C. And a frost will still be a possibility in the Alps.

Monday will remain sunny and dry, signalling the beginning of April. Highs of 22C are expected and the wind will remain at a minimum.

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.
