Infrastructure development in this region, including that related to energy, has been very limited and deals with many restrictions, due to limited access and high costs of transportation to and from the region. In many villages of this region the electricity need is considered to be urgent, for example, electricity needs for public lighting, radio communication for external contact, electrical devises for the village clinics (as refrigerators, freezers or electric microscope), and electrical pumps for fresh water supply. Isolation, thus high prices bounded to the import of materials, fuel, or other requirements, make the operation and management of any energy system a challenge, as it is to achieve a sustainable energy development for this region. Objective The main objective of this study is to describe the current state of the energy production, use and need in the Trio and Wayana areas (Brazil-Suriname border region), and to perform a qualitative techno-economic analysis to indicate possible required investment and operation costs of renewable electricity production systems, using Kwamalasamutu, the largest agglomeration in the area, as a case study. Kwamalasamutu was also chosen as the residence of the Granman, leader of the Trio people, and representative of the Trio and Wayana people in all external communication matters. In his official role, the Granman can facilitate the co-operation between NGO’s, International Organizations as the OAS and the local people for future energy development activities. Methodology and Results A visit was paid to Kwamalasamutu (Suriname) and a literature review was performed where all available energy related documentations or reports about the Suriname-Brazil border region were collected and used for describing past renewable energy projects as well as the current energy production and use. Based on this review, a qualitative energy resource assessment and a techno- economic analysis, recommendations are made on how to implement a sustainable energy development strategy. Energy analysis Demographic data of Kwamalasamutu was collected and an attempt was made to create an inventory of the amount of households, public buildings, and infrastructure and currently used electrical production systems. Additionally, an inventory was made of the electrical appliances and their specific energy requirements that are used in each building. The current electricity production was analyzed and energy demand projections were made based on two scenarios: - Scenario K1 entails the electricity demand (164 Wh/day) to cover the basic needs,
