The Hydro Empowerment Network (HPNET) is a South-South knowledge exchange and advocacy platform to advance small-scale (<1MW) hydropower. Its approach is to strengthen the work of local practitioners who partner with rural communities to establish sustainable hydro mini-grids. With 150+ members with diverse backgrounds across the globe, HPNET's primary objective is to facilitate collaboration and partnerships that advance technology and capacity development, access to financing, socio-environmental approaches, and evidence-based advocacy for sustainable and equitable micro/mini hydropower in the global South.
