Oman Future Fund (FFO), a subsidiary of Oman's sovereign wealth fund, has decided to invest 60 million Omani riyals (US$156 million) in the polysilicon factory being built by Oman United Solar Polysilicon (FZC) SPC in the Sohar Free Trade Zone between Dubai and Muscat, the capital of Oman. The factory covers an area of 160,000 square meters, with an estimated total investment of US$1.35 billion (equivalent to about RMB 9.4 billion), and an annual production capacity of 100,000 tons of high-purity polysilicon. It is scheduled to be put into production next year. Rashid Sultan Al Hashmi, senior manager of FFO, said: "This new factory will enhance Oman's position in the renewable energy market and serve as a catalyst for further foreign direct investment (FDI). It is expected to further attract investment in the downstream of Oman's solar manufacturing value chain." (Sovereign wealth fund: Corresponding to private wealth, it refers to public wealth accumulated by a government through specific taxes and budget allocations, renewable natural resource income and international balance of payments surpluses, which is controlled and controlled by the government and usually held in foreign currency.)
