Tierra Grata

About us?
We provide access to clean energy, water and safe sanitation to rural communities through decentralized, affordable and non-polluting solutions.
Users subscribe to our services and through an interest-free credit acquire the different solutions through monthly payments adjusted to their income.
We accompany the services with a social intervention program that aims to generate capacities within the communities. With our Guardians program, we establish a management committee that becomes the technical team in charge of monitoring and repairing the installed solutions, guaranteeing long-term sustainability.
