Gamesa will install its specially designed low-air-density turbines at the 48MW Cangfang project in Yunnan, southern China.
The 24 G90-2MW turbines will be adapted to deal with the altitude and low temperatures, Gamesa said.
Turbine delivery is expected in May, with commissioning due before the end of 2016.
Gamesa has also won a 50MW order from the Hebei Construction and Investment Group for the Senjitu II project in Hebei province, north-east China.
The order will supply 25 G97 2MW turbines to the second phase of the project, after Gamesa was contracted to supply the first phase in April.
The order is part of a 150MW supply agreement between Gamesa and Hebei Construction signed in September 2014.
A final order for the third 50MW phase of Senjitu II is expected later this year, according to Gamesa.
"I believe in the following decade China will continue to be the most prosperous wind market in the world. And we hope Gamesa will continue to play an important role in China's wind developments," said Alvaro Bilbao, Gamesa's CEO in China, last year at China Wind Power 2015.
