Having invested US$700 million in 2009 to build silicon wafer production facilities with a total nameplate capacity of 2GW, GCL-Poly Energy will invest a further US$300 million to boost wafer production capacity by a further 1GW. The company has production facilities in Wuxi, Xuzhou, Changzhou, and Suzhou, China. The company noted that wafer capacity has ramped up to 1.2GW as of June.

The latest round of expenditures was said to enable the company to produce both monocrystalline and multicrystalline wafers at a new facility to be constructed in Jiangsu Province. The plant is expected to be fully ramped up by the end of this year.
