As part of two of the deals, Gamesa will also be responsible for the construction of the projects.
Gamesa was unable to name the customer in each of the orders.
The first engineering, procurement and construction (EPC) deal with a "renewable energy player" will see Gamesa install 25 G97 2MW turbines at a 50MW site in Gujarat, northwest India. The project is due for completion in September.
Gamesa will install a further 15 G97 turbines under the second EPC contract with a "power supplier". The project is located in Madhya Pradesh and is expected online in the first quarter of 2016.
The final deal with an "important independent local operator and developer" is for a project also in Madhya Pradesh. Gamesa will deliver 25 G97 turbines and will provide "long-term" servicing when the project is completed in early 2016.
