Fraunhofer Institute for Solar Energy Systems ISE, a Germany energy research institute, has announced significant shifts in the EU power mix in H1 2025. German solar generation rose by 30% YoY to 40.0 TWh, while wind production fell to 60.3 TWh from 73.4 TWh. Consequently, Germany's net public electricity generation from renewable sources dropped to 60.9% from 65.1% during H1 2024. Total solar and wind output in the EU dropped to 344.4 TWh from 358.1 TWh, as stated by Fraunhofer ISE. Solar production has increased in France to 15.1 TWh, in Belgium to 5.6 TWh, in Denmark to 2.3 TWh, and in Poland to 10.3 TWh. Germany imported 7.7 TWh of power, mostly from Scandinavia, because of cheaper hydro and wind electricity. Electricity exchange prices averaged €86.64/MWh (~ $101.37/MWh), while retail electricity prices in Germany returned to 2021 levels, averaging €0.27/kWh (~ $0.32/kWh).
Fraunhofer reports solar growth, tighter EU renewable mix
Solar generation increased across Germany and EU in H1 2025, but weak wind output led to a drop in total renewable electricity share, Fraunhofer ISE reported.
