In 2005, with the aim of fulfilling external cooperation and assistance tasks in the field of small hydropower undertaken by the Ministry of Water Resources, and addressing the restriction whereby public institutions were unable to obtain permission for import and export business operations, the International Center on Small Hydro Power (ICSHP) fully invested and registered Hangzhou South-South Hydropower Development Co., Ltd. In 2023, it was renamed Hangzhou South-South Innovation Green Technology Development Co., Ltd. (HSS). The primary scope of operations includes small hydropower equipment export, equipment installation, technical renovation of hydropower stations, and training. Since its establishment, Hangzhou South-South Innovation Green Technology Development Co., Ltd. has primarily undertaken the export of related equipment and associated services for external assistance projects of the International Center on Small Hydro Power. It has successively undertaken equipment exports and subsequent technical service work for more than 10 countries across several continents, including Mali, Nigeria, Zambia, Kenya, North Korea, Micronesia, and Tanzania. These endeavors and achievements have not only made significant contributions to the smooth completion of external assistance projects by the center but have also achieved certain accomplishments in the field of international small hydropower cooperation, thus enhancing the international reputation of Chinese small hydropower.
