ACCIONA Energía has completed the repowering of its Tahivilla wind farm in Tarifa, Spain, which has now entered full commissioning.

The site, with an installed capacity of 84.4MW, has undergone a redevelopment that replaced 98 turbines with 13 new units.

This upgrade is projected to boost annual electricity production by 72% to approximately 254 gigawatt-hours (GWh) per year, while maintaining the same export capacity.

The increased output is expected to avoid around 108,000 tonnes per annum (tpa) of carbon dioxide (CO₂) emissions.

A 15-year power purchase agreement with a private client underpins the project, providing revenue certainty and supporting the investment required for modernisation.

ACCIONA Energía also received funding amounting to €8.3m ($9.8m) from Spain’s Recovery, Transformation and Resilience Plan (PRTR), financed by the EU's NextGenerationEU programme.

More than 1,000 jobs were created during the dismantling of the old facility and construction of the upgraded wind farm.

The reduction in turbine numbers allowed for optimisation of land use and the wind farm’s environmental integration, while extending the operational lifespan.

Repowering projects like Tahivilla may also offer certain benefits compared to building new installations in terms of social acceptance in areas accustomed to renewables, and reduced environmental impact through infrastructure reuse and fewer turbines.

Such projects can also result in shorter development periods along with lower investment costs and risks.

In December 2025, ACCIONA Energía begun delivering renewable energy to the grid from its Logrosán biomass facility in Cáceres, Spain.

With a capacity of 50MW, the plant is set to generate 380GWh of electricity annually, helping to prevent more than 187,000tpa of CO₂ emissions.
