Nineteen families in Ecuador’s Intag Valley are building a 300-kilowatt run-of-river hydropower plant that allocates half its revenue to conservation while offering an alternative income source to mining and large-scale agriculture in Imbabura province. The HidroAguagrún project, registered as a business since 2022 with 90% community ownership, provides a test case for replicating decentralized renewable energy models in biodiverse regions facing extractive industry pressure. Replicability hinges on community cohesion, water availability, and access to technical and financial support structures similar to those deployed in Intag.
