PVTIME – Analysis from the European Climate Neutrality Observatory reveals that grid constraints, lengthy permitting processes and limited system flexibility are collectively hindering the expansion of solar and wind power across Europe’s energy portfolio.
The think tank’s annual review monitors the EU’s progress towards carbon neutrality. Although variable renewables generated 30% of European electricity in 2025, growth since 2020 has been too slow to reach the bloc’s 2030 target of 58% renewable power.
Total new wind and solar capacity reached approximately 70GW in 2024, in line with projections. Solar dominated this expansion with 57.5GW, while wind additions fell by around 2GW compared to 2023 levels. Wind’s higher capacity factor means that the weaker wind rollout has dragged down overall renewable power output far more than expected.
ECNO identifies inadequate investment in grids, battery storage and smart meters as key barriers. It calls for faster permit approvals, more coordinated cross-border grid planning, and stronger financial incentives for flexible zero-carbon generation.
Although grid investment has increased year on year between 2020 and 2025, progress is too slow. The report’s modelling shows that distribution network spending must increase by between 12% and 25% each year in order to accommodate new clean energy assets. Although battery storage stockpiles have expanded, they still fall short of the European Commission’s 2030 requirements.
EU renewable energy policy yields inconsistent results at the supranational and national levels. While the Net Zero Industry Act provides a vital foundational framework, other policy tools offer limited stimulus for clean energy deployment.
EU grid governance suffers from fragmented oversight. National authorities hold most of the power over grid planning and funding, creating a misalignment between EU-wide rules and national regulators’ obligations that hinders unified, cross-border action.
Recent EU guidance and draft legislation aimed at accelerating grid and storage permitting processes and designing flexible power tariffs represent significant progress, yet they fail to address the fundamental bottlenecks. The forthcoming EU power market integration White Paper, due for publication this year, will play a key role in unifying regional power markets, improving the absorption of renewable and flexible assets, and reducing overall system operating costs. All member states are advised to align grid planning with the expansion of renewable energy sources, speed up project clearances, and increase investment in transmission and distribution.
The report also highlights a significant additional risk to the EU’s energy transition: increasing dependence on Chinese suppliers for essential raw materials, battery components, solar inverters, and critical manufacturing supplies. Concentrated supply chain reliance exposes deep structural industrial vulnerabilities. The EU’s long-term economic resilience and industrial competitiveness depend on reducing fossil fuel imports, diversifying core supply chains, and accelerating the delivery of carbon neutrality. The bloc has already introduced targeted policies to mitigate this supply chain exposure.
