On November 18, 2025, the 3rd plenary meeting of ISO/TC339 (small hydropower plants) was convened in Beijing, adopting a hybrid format that combined online and in-person participation.
Opening remarks were delivered by Madam Ni Li from the Ministry of Water Resources (MWR) and Ms. Zhang Mengmeng from the Standardization Administration of China (SAC). The meeting registered 45 delegates from nine countries, including China, India, Indonesia, and Nigeria, alongside representatives from international bodies including the United Nations Industrial Development Organization (UNIDO), IEC/TC 4, and the ISO/TC339 Secretariat.
Ms. Hu Xiaobo, the committee manager, reported on the work progress of ISO/TC339 and introduced ISO code of ethics and conducts. Mr. Cui Zhenhua, the convenor of Working Group 1 (WG1), presented the progress on the "Small Hydropower - Vocabulary" project. Madam Huang Yan, Head of the Chinese Delegation, provided an update on the newly approved new work item roposal "Small Hydropower - Site Selection Planning." The meeting discussed and approved the proposal to establish a working group for site selection planning, along with other new project suggestions and arrangements for the next plenary meeting.
ISO/TC339 was officially established in 2022 and currently comprises 14 P-members and 17 O-members. In recent years, the International Center on Small Hydro Power, serving as both the Secretariat of ISO/TC339 and the domestic mirror committee, has achieved significant progress in advancing the standardization of small hydropower. It has successfully facilitated the initiation of two international standard projects on small hydropower led by China. The establishment of ISO/TC339 has provided an essential platform for technical standards exchange to promote the sustainable development of small hydropower globally. Moving forward, the ISO/TC339 will continue to foster collaboration among member countries and relevant international organizations, accelerate the development of high-quality international standards tailored to the development needs of various nations, and contribute to a shared future for humanity through international standardization in small hydropower.
