Jeju gamgyul grown using renewable energy-based production methods has officially entered commercial distribution, marking the first time such citrus has reached the market in Korea. The launch reflects the successful outcome of a demonstration project led by the Jeju Agricultural Research and Extension Services and confirms that a new production approach is ready for full-scale commercialization.
On the 26th, Jeju held a launch event at the Jeju Agricultural Research and Extension Services to announce the official shipment of the gamgyul. The citrus was cultivated using only on-site renewable energy systems, including solar power facilities, air-source heat pumps, and energy storage systems (ESS). Heating and operational electricity were supplied entirely by power generated within the farm, without relying on external power grids.
The research institute has conducted field trials since 2025 to apply renewable energy systems to gamgyul cultivation. Infrastructure installation, operational verification, and certification procedures have been completed, and the current shipment confirms that the system is ready for commercial-scale production. This project also represents Korea’s first fruit production case applying RE100 standards in actual distribution.
Beginning this month, Jeju will introduce the new production method to two gamgyul greenhouse farms equipped with solar facilities. Financial support has been allocated to assist with facility adoption, and the number of participating farms will be expanded in stages.
Jeju also plans to develop standardized greenhouse design models using film-type solar panels within this year. By 2027, detailed production manuals covering facility standards, energy operation methods, and crop management practices will be established to support wider field application.
Going forward, Jeju intends to gradually expand the renewable energy-based gamgyul production approach and strengthen market competitiveness through certification and branding initiatives.
