The European wind‑energy community is closely watching a proposal by finance ministers from Austria, Germany, Spain, Portugal and Italy to the European Commission for a new tax on electricity‑sector companies – a move that could reshape investment dynamics across the continent. Spain’s experience, where wind now supplies 22 % of electricity and renewables overall account for 65 % of the generation mix, illustrates how wind can keep power prices insulated from volatile fossil‑fuel markets, a model the EU would be risking by adding fiscal pressure.
Wind’s impact is already evident in the numbers. The Spanish spot market recorded an average price of €41.71 /MWh in March, well below the €52.62 /MWh gas price, effectively decoupling electricity from international fuel costs. This price advantage translates into annual consumer savings of more than €4.8 billion – roughly €20 /MWh in the spot market. Moreover, households on the regulated PVPC tariff paid 5 % less than in March 2019 and 64 % less than during the 2022 energy crisis, underscoring wind’s role as a cost‑saving, not cost‑adding, technology.
“Wind power is the most cost‑effective renewable and the only technology that can reliably supply electricity at all hours,” says Dr. Maria Hernández, senior analyst at the European Wind Energy Association. “Introducing additional taxes now would create regulatory uncertainty, deterring the capital needed to expand both on‑shore and offshore wind farms, and to pursue hybrid projects that pair wind with green hydrogen.”
The sector’s strategic importance extends beyond the on‑shore park. Offshore wind farms, now under rapid development in the North Sea and the Mediterranean, promise higher capacity factors and can be directly coupled with green‑hydrogen production, providing a clean storage solution for excess power. Such hybridization aligns with the EU’s ambition to become a global leader in renewable energy technologies.
The proposed tax would therefore jeopardize Spain’s progress toward SDG 7 (Affordable and Clean Energy) and SDG 13 (Climate Action). By limiting new wind installations, the country could lose up to 0.4 MtCO₂e /year of avoided emissions—equivalent to the annual emissions of roughly 90,000 passenger cars—while also missing out on the economic multiplier that wind brings to local manufacturing and job creation.
If policy makers fail to safeguard the wind sector’s growth, the continent risks a reinforced dependence on imported fossil fuels, higher electricity bills for citizens, and a slowdown in the transition to a low‑carbon economy. The wind‑energy community urges a clear regulatory framework that encourages investment, accelerates deployment, and avoids additional fiscal burdens—ensuring that the momentum built over the past decade is not undone.
