Renewables Supply 57% of Germany’s Power as Solar Surge Fuels Policy Clash

A decentralised alternative to a proposed gas buildout gains momentum following data showing solar offset wind shortfalls.

Overview

  • Preliminary figures from ZSW and BDEW show renewables covered about 57% of electricity use in the first three quarters of 2025, with 366.0 TWh gross generation and 216.0 TWh from renewable sources.
  • Photovoltaic output rose roughly 24% year to date while onshore wind fell about 12% after a wind‑poor first quarter, and analysts say stronger autumn winds could lift the full‑year share.
  • Economy and energy minister Katherina Reiche proposes commissioning at least 20 GW of new gas‑fired capacity and trimming support for small rooftop PV, though coalition decisions remain open.
  • An alliance of 21 companies presented a Roland Berger study estimating €185–255 billion in net economic benefit from decentralised PV, batteries, heat pumps and smart charging through 2045, including €14–18 billion in consumer savings.
  • The study warns against overreliance on gas due to cost and geopolitical risks, and EU state‑aid clearance for large gas tenders remains uncertain after earlier hurdles on smaller plans.
