The company will remove the 90 22-year-old turbines at Acciona Energia's 30MW El Cabrito project in Andalucía, southern Spain, in the second half of next year, the company said.
The site’s 330kW turbines will be replaced with with just eight N100 3MW and four AW70 1.5MW machines.
El Cabrito will have a reduced operating cost due to the lower number of turbines, and an increased energy yield despite having a slightly lower nominal capacity, Nordex stated.
The manufacturer also argued that the landscape around the town of Tarifa, near where the wind farm is situated, will be "improved aesthetically" due to the reduced number of turbines.
"This project is something of an ideal constellation for us, as with it we can demonstrate that wind power has gained substantially in efficiency and show that this kind of project makes good ecological and economic sense," Patxi Landa, Nordex’s chief sales officer explained.
The contract provides for the delivery of the turbines as well as a guarantee for an initial period of two years.
Earlier this month, Spanish wind energy association AEE published a growth plan in which the country should reach 40GW of installed capacity by 2030.
Repowering of ageing wind farms, as well as new installations, is considered "a must" to Spain meeting this target of an additional 17GW of capacity, the AEE stated
