Nordex will supply turbines to developer Central Puerto, which won power deals in Argentina's October auction.
A total of 32 AW125/3000 turbines will be delivered to the La Castellana project, with a further 15 of the 3MW machines set for the Archiras site.
Nordex said construction is set to begin by the end of 2017, with completion in 2018.
It is the first time Nordex has won an order in the country. It is further evidence of the growth potential the German manufacturer gained with its acquisition of Acciona Windpower in April 2016.
In the October auction, the government awarded contracts for a total of 1,109MW, dominated by 708MW of wind energy and 400MW of solar power.
