Shanghai Aeolon Wind Energy Technology Development Co recently signed an investment agreement to expand its wind turbine blade production center in Haimen, a county-level city in Nantong, East China's Jiangsu province.

The project will receive 3 billion yuan ($423.9 million) in investment and will be the largest of its kind in the world in terms of sales revenue.

In 2018, the company spent 2.02 billion yuan building a high-power wind turbine blade production center in Haimen, which occupies an area of 575 mu (38.35 hectares). It is the company's sixth production center in China.

The center began trial operations in March 2019 and achieved a taxable sales revenue of 600 million yuan by the end of the year. 

It has been at full production capacity since resuming operations in March. All 16 of its production lines are running at full capacity, and more than 2,200 employees have returned to work. Its sales revenue is expected to reach 2.5 billion yuan this year.

As the number of orders keeps increasing, the company decided to expand the center with another 29 hectares of land to the north. New manufacturing plants, office buildings and warehouses will be built for the research and development, production, sale, maintenance and testing of wind power generation facilities and relevant compound materials.

Construction is expected to start in late June. Upon completion, the total sales revenue of the Haimen center will surpass 10 billion yuan.

"We chose Haimen for its advanced transportation network and the highly efficient government services," said a spokesperson for the company. "It only took eight months from the signing of the agreement for the current center to begin trial operations."
