Senvion will supply 50 3.4MW turbines to the 170MW Sarco project in the Atacama region of northern Chile. A further 43 3MW turbines will be delivered to the 129MW Aurora site in Los Lagos, southern Chile. Both projects are due online in 2017.
Aela Energia, the joint venture between Mainstream Renewable Power and private equity firm Actis, is developing the projects.
"These projects were awarded under a competitive tendering programme last year in which wind energy prices came in below fossil-fuel prices, clearly demonstrating once again that renewable energy is cheaper than fossil-fuel generation," said Mainstream CEO Eddie O'Connor.
It is Senvion's first contract in Chile as the company looks to expand beyond Europe into emerging markets.
This expansion is part of the plan put in place after the manufacturer was acquired by private equity firms Centrebridge Partners and Arpwood Capital.
"South Cone South America is a key part of this strategic growth plan, and with this major contract in Chile, we prove that Senvion is well positioned to expand our activities in our new markets outside of Europe," said Senvion CEO Jürgen Geissinger.
