Woman of Waterpower 2022
08 March, 2023
The Women in Renewable Energy network and WaterPower Canada announced that Christine Monette from Andritz Hydro in Canada was the recipient of the Woman of Waterpower Award for 2022. The award is designed to highlight and celebrate women who go to tremendous lengths to support, build and promote Canada’s hydropower industry, and are role models, mentors, educators and leaders to their peers and colleagues. IWP&DC asked Monette to share her experiences of the hydropower industry with us.

International Norms for small hydropower
10 August, 2011
Due to the shortage of finance and technology, many developing countries have to overcome various obstacles in order to develop small hydro projects. One such obstacle is the absence of international norms, To achieve an early normalization and standardization of SHP development, it has become necessary to compile a complete international norm on SHP so that global SHP exploitation could be stimulated effectively. By Ms Xialei, Cheng and Mr Daqing Pan
