Jiangsu Zhongneng Polysilicon Technology Development, a subsidiary of GCL-Poly, has begun commercial operations at its 200,000MT hydrochlorination facilities. The facilities ensure the stable production of polysilicon and significant upgrade of product quality to a higher level, allowing full recycling of by-products, and achieving lower polysilicon production cost to reach levels similar to that of global incumbents.
This hydrochlorination project was a significant element in the technical improvement program initiated by Jiangsu Zhongneng in 2010, with the aim of increasing polysilicon production volume and enhancing the competitiveness of GCL-Poly’s polysilicon products.

The technical improvement program marked the cooperation between the GCL-Poly’s R&D center and other leading polysilicon technical service providers in the U.S. via the application of advanced technologies such as hydrochlorination.
Since the technical improvement program, the company’s hydrochlorination facilities have reached a total capacity of 500,000MT per annum, which can fully satisfy the recycling requirements for polysilicon production. The company said it expects to bring down polysilicon production cost to reach levels similar to that of leading incumbents after the 200,000MT facilities have been fully ramped up.
Shu Hua, executive director and president of GCL-Poly, said, “The operation of the 200,000MT facilities marks an important milestone taken by Jiangsu Zhongneng towards enhancing product competitiveness. Through supplying a large quantity of high-quality polysilicon at competitive prices, GCL-Poly will play a significant role in the rapid development of the solar industry in China and elsewhere and contribute significantly to the adoption of solar power generation.”
