Recently, there are rumors that the 100,000-ton polysilicon plant of Oman United Solar Energy Company has been completely shut down, and the process, equipment and operation technology teams stationed in China have received a holiday notice and are leaving for home in batches, with a tentative period of six months.
Up to now, there is no official announcement.
Previous information showed that the project was supported by Oman Sovereign Fund and IFC, with a total investment of $1.6 billion, to build 100000 tons of polysilicon production capacity, corresponding to about 40 GW of component production. It is positioned as a polysilicon supply base for the American and Indian markets.
After the base opened the whole process in February 2026, only the first 50,000-ton production line is in the climbing certification stage, and the second production line has not yet been clearly started. However, the industry generally believes that its core challenge has shifted from completion and production to stable and profitable shipments, and the rumor is still pending verification.
