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 (COâ‚‚) 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 EnergÃa 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.

By GlobalDataMore 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 EnergÃa 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 COâ‚‚ emissions.
