Wind turbines, crucial to Germany’s energy transition, generated less electricity in 2025 despite a strong expansion of installed capacity, preliminary data shows, DPA reports.

TenneT, one of Germany’s four electricity transmission system operators, said a total of 132.6 terawatt hours (TWh) of onshore and offshore wind power was produced last year, down from 138.3 TWh in 2024.

If all production sources are included, a total of 437.6 TWh of electricity was produced in Germany in 2025, according to the German Federal Grid Agency, which regulates the country’s electricity and gas networks.

The decrease in wind power production is explained by weather conditions, according to Agerpres.

‘In 2025, there was only a moderate breeze, especially onshore; under normal conditions, the production of wind farms would have been significantly higher due to the expansion of installed wind power capacity,’ reported 50Hertz, the grid operator responsible for the Baltic Sea. The company said that 2023 was the year in which the wind had the strongest intensity in more than 20 years, while 2024 was around the long-term average.

On the other hand, offshore wind power production remained stable or increased. According to TenneT, a total of 20.8 TWh of offshore wind power was transmitted to the shore in the North Sea last year, a comparable amount in 2024. This amount is enough to cover the annual electricity needs of around 6.5 million households in Germany.

In parallel, six offshore wind farms in the Baltic Sea generated around 5.4 TWh of electricity in 2025, around 10% more than the previous year, according to 50Hertz. This amount would cover the energy consumption of the city of Leipzig and the surrounding area.

Last month, Germany’s energy regulator reported that in 2025, Germany’s total installed renewable energy production capacity had increased by 11% to around 210 gigawatts. Germany’s onshore wind capacity has now reached 68.1 gigawatts, the German Federal Grid Agency pointed out. According to government goals, this figure would increase to 115 Gigawatts in 2030.
