Vestas will deliver 24 of its V110-2.0 MW wind turbines as part of the deal, which also includes a three-year Active Output Management 4000 service contract and a SCADA VestasOnline Business for data-driven monitoring and preventive maintenance.

The company expects to deliver and commission the turbines in the final quarter of this year.

China Longyuan Power Group vice general manager Huang Qun said: "We decided to work with Vestas once again on this project, based on our previous experience with their turbines’ reliability on our many diverse wind sites – and we are of course expecting this project to be another successful cooperation."

China accounted for nearly half of the world’s wind power installation in 2015.

Vestas has been operating in China since 1986, when it erected three turbines as part of the country’s first ever wind farm. The three turbines ran well for 29 years until being retired in 2015.

Vestas Asia Pacific and China president Chris Beaufait said: "As we celebrate Vestas’ 30th anniversary in China this month, we are pleased to build on our long-term partnership with Longyuan, and we believe that this new order once again emphasises that Vestas is a valued partner for our Chinese customers."

China Longyuan Power Group was established in 1993. It mainly designs, develops, manages and operates wind power plants.
