The order from the Indian developer is for 25 G97-2.0MW turbines and 29 smaller G58 850kW machines.
Gamesa India chairman and managing director Ramesh Kymal said: "With this order, Gamesa India's overall presence and visibility would increase in the entire state of Maharashtra expecially in the most successful G97-2.0MW platform."
The manufacturer launched the G97 earlier this year especially for low-wind sites.
The state of Maharashtra is noted for its lower wind speeds.
Sumant Sinha, chairman and CEO of Renew Power, said: "[This] partnership is an important step towards positioning Renew as one of the leading renewable independent power producers in India."
Gamesa sold 14% of its turbines to the Indian market in the first half of 2012.
