Gamesa will deliver 125 of its low-wind G97-2MW turbines to the projects. The G97 was the firm's best-selling turbine in 2014.
The first project is located near Ananthapur in the south-east state of Andhra Pradesh. Gamesa will provide turnkey services to build the 100MW site, with commissioning expected in March 2016.
Gamesa will also supply and install its turbines at the 100MW Agar and 50MW Ratlam projects in the central state of Madhya Pradesh. Both projects will also be online in 2016.
It is the second time in 2015 Orange has specified Gamesa turbines. In January, Gamesa won a 50MW deal from the independent power producer to supply the G97 to the Khanapur project in Maharashtra, west India.
Including this deal, Gamesa has secured 500MW of orders in India in 2015, all of which will be made up of G97 turbines.
