Seoul-based OCI Holdings planned to invest $265 million to build a solar cell production facility at its US subsidiary, Mission Solar Energy. Production was expected to start with 1 GW in early 2026 and grow to over 2 GW by the end of the year. The plant would use polysilicon from OCI TerraSus in Malaysia, avoiding China-linked supply chains and meeting US trade rules. The project would use existing factory space and pre-approved permits to save time and costs. It would also qualify for US tax credits under the Inflation Reduction Act. The new facility aimed to help meet a major shortage in US solar cell supply. The decision came as changes in US trade policies made the company choose to set up its own subsidiary.
