Naturgy, in collaboration with Vestas, is undertaking a major upgrade of the Somozas Wind Farm in A Coruña, Spain. As part of the company’s repowering strategy, the project will replace 81 outdated turbines with just 9 modern, high-efficiency units. This initiative is supported by €67 million in funding from the European Union’s NextGenerationEU program and showcases how new technology can deliver more energy with fewer machines.

Bigger Output with Fewer Turbines
Despite a slight decrease in installed capacity—from 49.6 MW to 46.4 MW—the repowered Somozas Wind Farm is expected to increase annual output to 168 GWh, enough to supply electricity to around 48,000 homes. Vestas will provide seven V150-6.0 MW and two V110-2.2 MW turbines, supported by a 10-year AOM 4000 service agreement. Delivery is expected by Q4 2025, with commissioning planned for Q2 2026.
Sustainable Construction and Recycling
The project emphasizes sustainability by reusing existing infrastructure, such as roads, evacuation systems, and buildings, which helps reduce land use and construction costs. During decommissioning, more than 10.5 million kilograms of materials will be managed. Approximately 75% will be steel, 17% cement and aggregates, and the remainder components like copper and fiberglass. Only a small portion will need special treatment.
Substation Upgrades and Environmental Restoration
As part of the modernization, the electrical substation will be upgraded to accommodate the new turbine configuration. Additionally, Naturgy will carry out ecological restoration in surrounding areas to better integrate the wind farm visually with the landscape and minimize environmental impact.
Part of a Larger Renewable Strategy
The Somozas Wind Farm project is one of three major repowering efforts by Naturgy in Galicia. Other projects include Monte Redondo, where 66 turbines will be replaced by 11, and the Novo Wind Farm, which will go from 25 to just 5 turbines. These upgrades highlight Naturgy’s commitment to building a more efficient and sustainable energy system.
With advanced turbine technology and a focus on sustainability, the Somozas Wind Farm stands as a powerful example of how fewer turbines can now deliver greater energy, helping to power the transition to a cleaner future.
