"China’s wind power industry continued to develop stably in the first half of 2018," Goldwind chairman Wu Gang said.
"Goldwind has maximised competitive advantages in the industrial chain, performed well in product sales and digital solutions, and actively expanded both domestic and overseas market, which led to continuous progress in our comprehensive capabilities," Wu added.

As well as its first half results, Goldwind also announced the start of commercial operations at the 82MW Punta Sierra project in Chile.

"Chile is one of our most important wind markets in South America. These two wind farms have helped Goldwind to set up a solid footprint in the region," said Goldwind South America general manager Liang Xuan.
