Solar, Wind Push Germany’s Renewables Power Mix to 58.8% in 2025

Germany recorded 437.6 terawatt hours (TWh) of actual power generation in 2025, almost unchanged from 437.7 TWh in 2024. Of the total generation mix, renewables accounted for 257.5 TWh, or 58.8%, compared with 58.5% in 2024.

Germany’s power generation declined marginally from 437.7 TWh in 2024 to 437.6 TWh in 2025, marking a 0.02% year-on-year (YoY) decrease. At the same time, the country saw growth in offshore wind generation, which increased from 25.7 TWh in 2024 to 26.1 TWh in 2025, representing a 1.56% YoY increase. Wind continued to contribute the largest share of total generation among all energy sources. Offshore wind fed 26.1 TWh into the general supply network (2024: 25.7 TWh), while onshore wind generated 106.5 TWh (2024: 112.6 TWh).

Germany recorded its strongest growth in solar power generation, which rose from 63.2 TWh in 2024 to 74.1 TWh in 2025. Solar generation totalled 74.1 TWh (2024: 63.2 TWh), while biomass generation stood at 36.0 TWh (2024: 36.2 TWh). The significant increase in solar output was primarily driven by above-average summer sunshine and growth in installed capacity.

The data was published by the Bundesnetzagentur in its electricity market report for 2025 and is based on information from SMARD, the agency’s electricity and gas market data platform.

Germany's conventional power generation declined 0.7% year-on-year to 180.1 TWh. Generation from hard coal increased 3.0% to 28.2 TWh, while lignite-based generation fell 5.4% to 67.2 TWh. Electricity generation from natural gas rose 6.4% to 60.6 TWh, increasing its share of total generation to 13.8%, compared with 13.0% in 2024.

Wholesale Electricity Prices

Bundesnetzagentur mentioned that Germany's average day-ahead wholesale electricity price in 2025 stood at €89.32 per megawatt hour (MWh), up 13.8% from €78.51/MWh in 2024.

Negative wholesale electricity prices were recorded during 573 of the 8,760 hours in 2025, compared with 457 of 8,784 hours in 2024. Prices exceeded €300/MWh in 40 hours in 2025, broadly in line with 41 hours recorded in 2024. (The difference in total hours reflects 2024 being a leap year.)

In 2024, the average price of a yearly futures contract for delivery in 2025 was approximately €88.70/MWh, nearly matching the average day-ahead price. In contrast, the average annual futures price in 2023 stood at €122.03/MWh, significantly higher than the realised day-ahead price.

Cross-Border Electricity Trade

In commercial cross-border trade, Germany imported 76.2 TWh of electricity in 2025 (2024: 77.2 TWh) and exported 54.3 TWh (2024: 48.9 TWh). Imports declined by around 1.3%, while exports rose 11.1%, resulting in a 22.6% reduction in net imports to 21.9 TWh.

Electricity imports typically occur when domestic generation is more expensive. Power generation and consumption are interconnected across Europe, with electricity produced where costs are lowest. Germany and other European countries benefit from these cross-border dynamics and favourable generation conditions.
