GE will provide a total of 81 turbines to the two projects in the Hebei province in northeast China.
The US firm will provide 54 2.75-120 turbines to the 148.5MW Senjitu III project, and 27 1.85-82.5 machines to the 49.95MW Qiansongba site.
New GE subsidiary LM Wind Power will provide blades for the Senjitu III turbines, the manufacturer said.
GE will be the third supplier to HECIC's Senjitu series of projects. Vestas supplied the 150MW Senjitu I site in 2016, while Gamesa is providing the three phases of 150MW Senjitu II, which is currently under construction, according to Windpower Intelligence, the research and data division of Windpower Monthly.
Electricity from the projects is set to be used to help power Chinese capital Beijing. China is aiming to source 15% of its energy from renewable energy by 2020.
It has been a productive couple of weeks for western OEMs in China. At the end of April, Vestas announced two turbine orders totalling 110MW in China from an unnamed customer.
