The onshore wind power plant Guangrao with a capacity of 50 megawatts (MW) was completed at the end of 2012. It is the first project jointly delivered and implemented by the two wind power joint ventures of Siemens and Shanghai Electric. The joint ventures delivered 20 SWT-2.5.-108 wind turbines with an output of 2.5 megawatts each and a rotor diameter of 108 meters. This also marks a key milestone for the two companies after signing their alliance agreements at the end of 2011. Since their beginning in 2013, the two joint ventures called Siemens Wind Power Turbines (Shanghai) Co., Ltd, and Shanghai Electric Wind Energy Co., Ltd., are now in full operation and ready to serve the world's largest wind power market.
