About Us

SESI was formed in 2010 to bring together a team of experienced clean energy experts and development practitioners with an integrated multidisciplinary approach to designing, engineering, operating, and maintaining energy systems using a variety of generation sources focused on clean and renewable technologies.

Projects have covered all stages of the development cycle, from project identification and scoping through prefeasibility and feasibility to implementation, monitoring and evaluation, operations and management.

SESI’s personnel and strategic partners have professional qualifications in engineering, software development, business management and social sciences.  Individual staff and key consultants have between five- and forty-years’ experience in developing countries in Africa, Asia, Latin America and the Pacific.
