Iberdrola’s €350 Million Tâmega Wind Project Accelerates Portugal’s Clean Energy Expansion and Industrial Development

Road transport of the blades

(IN BRIEF) Iberdrola has begun assembling turbines for the new Tâmega Wind Farm, which will become Portugal’s largest wind installation with 274 MW of capacity, 38 Vestas 7.2 MW turbines, and annual generation of 601 GWh. The €350 million project will supply energy to 128,000 homes and prevent more than 230,000 tonnes of CO₂ emissions each year. As Portugal’s first hybrid wind–hydro project, it will share grid infrastructure with the Tâmega Hydroelectric Complex, reducing costs and environmental impact while supporting national electrification goals. The construction will generate 700 direct jobs and involve several Portuguese companies, with turbine components manufactured across Europe. Strong sustainability measures include continuous environmental monitoring, biodiversity protection, and a landscape recovery plan. The project also incorporates cutting-edge logistics, such as blade-lift technology to transport 85-metre blades safely through challenging terrain. The wind farm reinforces Iberdrola’s leadership in renewable energy investment in Portugal, following more than €2.2 billion invested and 1,400 MW already installed.

(PRESS RELEASE) BILBAO, 11-Dec-2025 — /EuropaWire/ — Iberdrola has begun the assembly of wind turbines for what will become Portugal’s largest wind farm, the Tâmega Wind Farm, a €350 million project designed to accelerate the country’s energy transition and strengthen national energy independence. Once operational, the facility will generate enough electricity to supply 128,000 households, equivalent to the population of Valladolid, and will prevent more than 230,000 tonnes of CO₂ emissions annually. The project marks a major step forward for electrification in Portugal and supports the targets outlined in the National Energy and Climate Plan.

The development, which includes the Tâmega Norte and Tâmega Sur wind farms, forms part of the agreement between Iberdrola and the Norwegian sovereign wealth fund managed by Norges Bank Investment Management, and will be supported by a long-term Power Purchase Agreement (PPA). Standing out as Portugal’s first hybrid generation initiative, the wind farm will share grid connection infrastructure with the Tâmega Hydroelectric Complex, reducing overall system costs, enabling greater integration of renewable energy, and lowering environmental impact.

Located between the districts of Braga and Vila Real, the project will include 38 Vestas EnVentus V172 turbines, each with a 7.2 MW capacity—the most powerful onshore wind turbines currently available worldwide. With 85-metre blades and towers reaching 114 metres, the installation is expected to produce 601 GWh of energy per year.

The project will also deliver substantial economic benefits. At its construction peak, the wind farm will support 700 direct jobs and engage several Portuguese companies, including CJR, Conduril, Socorpena, Painhas, and Proef. Turbine components are being manufactured across multiple European countries, reinforcing the sector’s commitment to European industrial capacity and cross-border innovation.

Construction is scheduled to continue until the third quarter of 2026, with all turbine components expected to be delivered on site before the end of the first quarter.

Environmental commitment and monitoring

Environmental protection is central to the Tâmega Wind Farm’s development. Iberdrola is applying strict environmental protocols, including continuous monitoring by biologists and archaeologists to minimise ecological impact. Biodiversity assessments for birds, bats, mammals, flora, and habitats will inform additional conservation measures and expand scientific understanding of the region.

Once construction concludes, a Landscape Recovery Plan will ensure that the site is seamlessly integrated into the surrounding terrain, with further compensatory measures implemented to enhance local habitats. Iberdrola has also committed to maintaining open dialogue with communities to minimise social disruption and ensure transparency throughout the project.

Overcoming the logistics challenge: transporting 85-metre blades

More than 110 turbine blades will arrive through the Port of Aveiro before being transported inland using blade-lift technology, a first-of-its-kind logistics solution in Europe. This specialised transport system can rotate blades up to 60 degrees, allowing them to navigate sharp corners, inclines, and difficult terrain without altering existing roadways. The method significantly reduces environmental impact while ensuring safe and efficient delivery.

The Tâmega Wind Farm strengthens Iberdrola’s position as Portugal’s leading renewable energy investor over the past decade. With more than €2.2 billion invested and over 1,400 MW installed, the company remains one of Europe’s most influential energy players and a global leader in electrification and sustainable innovation.
