Iberdrola advances EUR 350 million Tamega wind complex, Portugal’s largest onshore project

Iberdrola has started turbine assembly at the 601 GWh-per-year Tamega wind complex in northern Portugal, a EUR 350 million project combining wind and hydropower infrastructure. The development will supply electricity equivalent to 128,000 households and avoid over 230,000 tonnes of CO₂ annually.

Iberdrola has begun installing wind turbines at the Tamega Norte and Tamega Sur wind farms in northern Portugal, marking a key milestone in what is set to become the country’s largest onshore wind project. The EUR 350 million development, located between Braga and Vila Real, will deploy 38 Vestas EnVentus V172 turbines rated at 7.2 MW each, delivering total annual generation of approximately 601 GWh.

The project is structured under an agreement with Norway’s sovereign wealth fund, managed by Norges Bank Investment Management, and will operate under a long-term power purchase agreement. By integrating wind capacity with the existing Tâmega hydroelectric system, the scheme utilizes shared grid infrastructure, lowering connection costs and accelerating renewable integration while limiting additional land disturbance.

Once operational, the facility is expected to supply power equivalent to the needs of around 128,000 households and prevent more than 230,000 tonnes of carbon dioxide emissions annually. Construction is scheduled through the third quarter of 2026, with turbine components transported via specialized blade-lift systems to navigate mountainous terrain.

The development strengthens Portugal’s renewable capacity under its National Energy and Climate Plan, with implications for grid stability, local employment and European supply chain participation in wind manufacturing and infrastructure services.
