Presenting SUNNY’s 1st Demo Site in Rwanda’s Mahama Refugee Camp: Transforming Lives with Clean Energy

Access to clean and sustainable energy is not just a technical challenge; it’s a fundamental aspect of improving lives.

In communities where resources are scarce, energy solutions can make the difference between survival and progress. At the Mahama Refugee Camp in Rwanda, the SUNNY project has taken its first major step toward this goal, working alongside partners PA, SOLHYD, and SOLEK to deliver innovative clean energy solutions.

Located in Rwanda’s Eastern Province, the Mahama Refugee Camp has been home to over 58,000 displaced individuals from Burundi and the Democratic Republic of Congo (DR Congo) since its establishment in 2015. While some progress has been made in introducing renewable energy sources, access to sustainable energy remains limited, impacting health, education, safety, and economic development for both refugees and the surrounding host communities.

Through the SUNNY project, we aim to test and implement pioneering solutions that will address these challenges, focusing on two key innovations: hydrogen-powered cooking systems and solar home systems.
