The plant, set to rise across about 4.63 square kilometers of land in Haenam County, South Jeolla Province, is scheduled for completion in June 2028. KOSEP selected a preferred EPC (engineering, procurement and construction) contractor for the project on Tuesday, one day before the announcement.
The chosen EPC firm will install about 640,000 solar modules incorporating cells manufactured exclusively at Hanwha Qcells' production facility in Jincheon, North Chungcheong Province — the company's largest domestic manufacturing base.
"This project offered an opportunity to demonstrate the competitiveness of Korean-made solar technology on a large scale," said Yu Jae-yeol, head of Hanwha Qcells' Korea business division, adding that sustained policy support for domestic renewable energy and locally produced components could help restore the country's solar supply chain and drive further investment.
The project arrives as South Korea pushes to expand its renewable energy capacity, with domestic manufacturers seeking to reclaim ground in a market long pressured by low-cost overseas competition.
