Vestas will supply 18 V110 2.2MW turbines to the Basavane Bagewadi proect in Bijapur, in the south-western state of Karnataka, and service the machines for 15 years.
The deal follows an initial 40MW order placed at the end of September for the first phase of the project with the same model of 2.2MW turbine.
The 80MW, two-phase site will be operational by the second quarter of 2018, Vestas said.
Vestas has over 3GW of capacity installed in India, and won more than 250MW of orders in 2017.
"This is our first project with Vestas, and we appreciate the Vestas team working closely with us from the earliest conceptual stage of this project and providing important value propositions to make this project successful," Atria director Sunder Raju said in September.
