DC(OCI) Cehmical in Korea rank No2 producer of polysilicon in Worldwide

Completion of OCI's Second Polysilicon Plant

- OCI becomes World's No. 2 polysilicon maker with 16,500 MT production capacity -

OCI commemorated the completion of its second polysilicon plant (P2) in Gunsan on September 29, 2009. Approximately 500 people attended the ceremony, including Chairman Soo Young Lee, President Woo Sug Baik and other executives from OCI, North Jeolla Province Governor Wanju Kim, National Assemblyman Bongkyun Kang, Gunsan Mayor Dongshin Moon, various officials from the central and provincial governments, key customers and Gunsan residents. The new plant has an annual production capacity of 10,000 metric tons.

OCI, the only Korean company that has been able to develop its own polysilicon manufacturing technology, invested a total of 1.01 trillion won in the Gunsan complex, and with the completion of its second polysilicon plant it now has a manufacturing capacity of 16,500 metric tons per year.

As a result, OCI is now the second largest polysilicon manufacturer in the world after Hemlock of the United States and is opening a new page in the history of the Korean chemical industry.

Over a three year period. OCI invested a total of 1.6 trillion won in the Gunsan area, thereby invigorating the regional economy and generating additional jobs. In addition, the plant is expected to yield over $1 billion/year in exports leading to greater generation of foreign exchange earnings.

OCI Chairman SooYoung Lee said during the ceremony, “Our No. 2 polysilicon plant has the largest manufacturing capacity in the world on a single plant basis. With the completion of the second polysilicon plant, it is expected that the North Jeolla region will become a mecca for the development of the solar industry through the creation of a “green energy cluster.”

In addition, with the second plant coming on-line, OCI occupy a better position than other companies in terms of economies of scale, thereby securing greater cost competitiveness. From a quality perspective, OCI is now supplying 10-nine (99.99999999%) purity product, which is one grade higher than the previously produced 9-nine (99.9999999%) product.

After OCI began commercial production of polysilicon in March 2008 with its first 5,000 metric ton plant, the company rapidly completed its second plant in record time, thereby receiving recognition for its technological skills.

With its successful entry into the polysilicon market, which has been dominated by the seven major producers for the past 40 years, OCI now has a solid base for producing product of world class standards, thereby contributing to the stable supply of polysilicon, a critical raw material for solar energy.

According to an OCI representative, “As a result of the treaty on climate change and the

supply of renewable energy, from 2010 the solar energy industry will play an important role in becoming an alternative energy source to fossil fuels.” He further added, “Once the regulations on global warming gases become established, it is expected that the industry will grow by 40-50% each year.”
