DC Chemical had a good nose for the market of the future. In 2000 the South Korean chemicals group began to develop its own technology to produce polysilicon based on the Siemens process in cooperation with the Korea Research Institute of Chemical Technology (KRICT).

But DC Chemical was right in betting on the rapidly growing polysilicon demand of the solar industry. The company was even a bit late when it started construction of its first polysilicon plant, which had an annual production capacity of 5,000 metric tons (MT), in August 2006. By that time, the polysilicon price on the spot market had already soared to almost US$300 per kilogram, up from US$28/kg in 2003. When the factory commenced commercial production in March 2008, it was at the last moment before the spot price began to decline again (polysilicon price trend).

In 2017 OCI purchased the new Malaysian polysilicon plant from Japanese manufacturer Tokuyama. The factory is fed by low-cost electricity from hydropower; however, Tokuyama was unable to fully ramp it up to its nameplate capacity of 20,000 MT and make it cost-competitive. OCI has revamped the plant to a capacity of 30,000 MT within three years.

Despite the economies of scale, the company’s production costs suffered from the high electricity rates in eastern China. Therefore, Zhongneng commissioned a captive power plant in 2015 to generate electricity at half of the cost that it paid for power supply from the grid before.

But that is not all. What Xinte, Daqo and Tongwei have in common is a big expansion leap to a capacity of roughly 80,000 MT in 2018/2019. All their new capacities are dedicated to high-purity polysilicon at low-cost locations, and all three have closed supply contracts with China-based Longi Green Energy Technology, the world’s largest manufacturer of monocrystalline solar wafers. Longi is planning to increase its wafer production capacity eightfold from 15 GW at the end of 2017 to 120 GW by the end of 2022.

That explains the massive capacity expansion at Xinte, Daqo and Tongwei. East Hope is not known for aspiring to produce high-purity material, but is also on an ambitious expansion course. Originally, the company was expected to double its capacity to 80,000 MT in 2020; instead, the capacity was increased to 70,000 MT in 2021.

Tongwei’s subsidiary Sichuan Yongxiang started to produce polysilicon in Leshan, Sichuan province with a small capacity of 1,000 MT in 2008, but with a bold target of 10,000 MT. Oversupply in 2011/2012 pushed this goal far out; only in 2015 did Yongxiang make a major leap from 4,000 MT to 15,000 MT. After another expansion to 20,000 MT in 2017, Tongwei thought big with two new plants for low-cost, high-purity polysilicon in Leshan and Baotou, Inner Mongolia. After both started up in late 2018, Tongwei reached a total capacity of 96,000 MT and became the global number one in 2020.

The German chemicals group is a polysilicon production pioneer; developed the Siemens process in the 1950s. After the initial public offering in 2006, strong expansion of solar-grade capacity at the factory in Burghausen. Opened two additional polysilicon plants with a capacity of 20,000 MT each in Nünchritz, Germany and Charleston, USA in 2011 and 2016, respectively. Consequently moved from the second rank to number one as the world’s largest polysilicon maker in 2016; was pushed off the throne by Tongwei in 2020 and will fall back further in the coming years.

The subsidiary of the Chinese transformer maker Tebian Electric Apparatus Stock Co., Ltd. (TBEA) was the first manufacturer that started polysilicon production in the Xinjiang Uyghur autonomous region in northwestern China (in 2009). Initial production capacity was only 1,500 MT, but the company became China’s second-largest polysilicon manufacturer after a capacity leap from 3,000 to 17,000 MT in 2013. Benefits from a captive, coal-fired power plant with extremely low electricity costs. Went public on the Stock Exchange of Hong Kong in late 2015.

Shanghai-headquartered, private East Hope Group was already running aluminum and silicon smelters in Xinjiang before it established Xinjiang East Hope New Energy to manufacture polysilicon. The first production line, which started up in 2017, has a nominal capacity of 15,000 MT, but an effective capacity of 20,000 MT. A second 20,000 MT line followed in 2018. East Hope originally planned the next step for 2020; however, the expansion to 70,000 MT was only completed in 2021. The company has extremely low electricity costs thanks to a captive, coal-fired power plant.

Located in Xining, the capital of the northwestern Chinese province of Qinghai, the private company is a child of the once leading Chinese solar cell and module producer Suntech Power. In 2006 Tihu Wang, Suntech’s vice general manager for research and development and previously a polysilicon materials scientist in the U.S., established Asia Silicon, which started production with a capacity of 1,000 MT in 2008. After a leap from 5,000 MT to 15,000 MT in 2015, further expansion to 20,000 MT in 2018. Benefits from low-cost electricity fed by hydropower.

Different from the hundreds of thousands of everyday forms of protest that mostly involve economic issues and target local governments in Mainland China, the Hong Kong protests directed their demands at the central government, and publicly challenged Beijing’s authority. The protests have had far-reaching ramifications for China’s governance model. The Chinese legislature passed the National Security Law in June, 2020, which grants Beijing broad powers to crack down on a variety of “political crimes.” The cleavages made salient in the Hong Kong protests between Hong Kong and Beijing, and between Hong Kongers and mainlanders, will haunt Hong Kong society for decades to come.
