Company chairman Zhou Jianxiong said that orders so far this year far outstrip those placed by this time last year.
The Chinese Wind Energy Association figures show that XEMC delivered a total of 1.1GW of turbines in 2013, up 27% on the previous year.
The company put the increased sales down to a fall in the cost of its main product, a 2MW direct-drive turbine suited to low-wind sites.
XEMC has also developed a 5MW turbine, which is being marketed as an offshore machine in China as well as being targeted at the onshore market in Europe.
