On February 5, the largest overseas polysilicon production base—United Solar Polysilicon’s (USP) 100,000-ton annual polysilicon project in Oman—officially commenced operations in the Sohar Free Zone, Oman. This project is not only a key component of the photovoltaic industry chain in the Middle East but also a new pivotal point connecting the PV supply chains across Europe, Africa, and Asia.
United Solar Polysilicon (USP) is the largest and only operational polysilicon production base in the Middle East, with an annual production capacity of 100,000 tons. It is expected to support the production of 40 GW of solar modules annually, generating sufficient electricity to meet the needs of up to 12 million households. Additionally, it is projected to reduce greenhouse gas emissions by 8.8 million tons per year. This facility will enhance the resilience and diversification of the global PV supply chain, expand the accessibility of clean energy, and ensure full traceability of its polysilicon production, further improving transparency and global competitiveness.
With a total investment of $1.6 billion, the factory is jointly funded by multiple parties. Oman remains the largest shareholder in United Solar Polysilicon—the Future Fund Oman (FFO), under the Oman Investment Authority, has provided approximately $260 million in funding for the project, an increase from the initial commitment of $156 million. This financing aims to expand polysilicon production capacity, create nearly 3,000 direct and indirect jobs, attract foreign investment, and support Oman’s vision of economic diversification while reducing its dependence on oil.
