Vestas has secured a 99MW order from Iberdrola to repower the latter’s 49.5MW Molar de Molinar and 48MW Isabela onshore wind farms in Castilla-La Mancha, Spain.
Under the terms of the contract, the wind turbine manufacturer will supply and install 11 V150-4.5 MW turbines for the Molar de Molinar wind farm and 11 V136-4.5 MW turbines for the Isabela wind farm.
Vestas has also signed a 10-year Active Output Management (AOM 4000) service agreement for the Spanish onshore wind facilities.
The repowering initiative will replace 139 older turbines with 22 advanced units, increasing energy output at the sites by approximately 30%.
Vestas Spain country manager José Luis del Cerro said: “This order underlines the great potential in repowering older onshore turbines with new and efficient technology.
“It also showcases the suitability of our 4MW portfolio for the Spanish market. Its full converter technology provides our customers with the reliability they need to operate in the Spanish grid, marked by an increasing participation of renewable sources.”
This upgradation is in line with Spain’s broader strategy to modernise its ageing wind infrastructure, with more than 9.9GW of installed capacity reaching 20 years of service by 2025.
By replacing legacy turbines with fewer, more efficient models, the project reduces land use and environmental impact while significantly enhancing onshore wind capacity.
Previously, the Molar de Molinar onshore wind site was equipped with 75 smaller turbines, while the Isabela wind farm had 64 turbines.
The new turbines are expected to be delivered by Q2 2025, with commissioning planned for the fourth quarter of the year.
Once operational, the repowered Spanish onshore wind farms will collectively prevent the emission of 53,000 tonnes of carbon dioxide annually.
Iberdrola renewable energy project development head José González Bujanda said: “The projects required to dismantle the old wind farms, and to adapt the foundations and electrical connections to host larger machines.
“The installation of more modern wind turbines will allow us to make better use of the wind resource, reducing the environmental impact.”
Earlier this month, Iberdrola España awarded EnergyLoop the contract to recycle blades and manage waste materials from the dismantled turbines of the Molar de Molinar and Isabela onshore wind farms.
