Samaj Unnayon Palli Sangstha (SDRS) is a non-government, non-profit humanitarian organization of Bangladesh, established in 2003. SDRS is dedicated since then to empower the most deprived families to reach economic self-sufficiency. During these years, this organization has been working for the development of poor and deprived people in remote and underprivileged communities in Bangladesh. Besides, until the present, SDRS works for development projects i.e. Private Sector Development, Women Economic Empowerment, Access to Health, Nutrition for Women, Adolescents and Children, WASH and Nutrition Integration, and Integrated Agriculture and Health Programme (IAHP). The IAHP included all major areas of action as like health and nutrition, seed systems, farm practices and cross-sectoral integration. Apart from this, we have a good exposure in working with indigenous and ethnic people, with a special attention on Alternative Medicine. SDRS has developed an innovative market-based strategy with a social objective for popularizing Solar Home Systems (SHSs) including other renewable energy technologies to millions of rural villagers. Currently SDRS is one of the fastest growing rural based renewable energy organizations of North Bengal. We implement country-wide programs in solar home system, domestic biogas, solar irrigation, and solar mini-grid based electricity generation plants. Moreover, we are planning to initiate a 50-MW solar plant to support the National Grid. As of June 2017, SDRS has installed more than 0.5 million Solar Home Systems in rural areas. We can use this opportunity in greater area as we are using updated technology, and contemporary market-based model that helps us to develop a sustainable relationship with end users. Moreover, SDRS is an effective partner of IDCOL for the mandate of Government. Currently SDRS has been operating its development activities in 35 districts directly working with about one hundred 25 thousand poor people.
