Goldwind (officially Goldwind Science & Technology Co., Ltd.) is a Chinese wind turbine manufacturer headquartered in Urumqi, Xinjiang, China. It is the second-largest China-based wind turbine manufacturer by 2011 market share and the third-largest in the world. Goldwind's initial use of the PMDD fully converted design came through its partner and eventual subsidiary VENSYS, with the VENSYS 62 which has been in operation since 2004. The PMDD design was integrated into the production of the 1.5MW PMDD wind turbines. Goldwind recently introduced the 2.5MW PMDD, which was designed to be lighter on a per-megawatt basis and even more cost efficient than the 1.5 MW variant. Currently, larger machines are under development that will be utilized for onshore and offshore locations.
