Sachi Graber

Senior Associate

Sachi is a former Senior Associate with RMI’s Africa Energy program. The Africa Energy program works to accelerate affordable, reliable, and clean energy access in sub-Saharan Africa by working closely with governments to develop robust and integrated national electrification strategies spanning on-grid and off-grid solutions. Sachi’s work with the Africa Energy team currently focuses on off-grid development in Nigeria, where she is helping to identify and expand opportunity for off-grid electricity systems through market analysis, holistic energy planning, minigrid system modeling, and project implementation. The team’s efforts in Nigeria will advise the national government, as well as utilities and off-grid system developers, on strategies for sustainable energy system growth. Sachi has led much of RMI’s work visiting and collecting data from rural communities, evaluating community electrification potential, and developing an undergrid minigrid strategy, and has also contributed to productive use/demand stimulation activities.


Prior to joining RMI in 2017, Sachi gained experience in energy systems and in sustainable development through her education and experience as a Peace Corps Volunteer. Her academic research has focused on rural renewable energy systems and development, including publications on solar minigrid policy and implementation in Uttar Pradesh, India. Before returning to graduate school, Sachi worked with the U.S. Peace Corps in Namibia for three years as a math and science education volunteer.

Letting Communities Lead

Picture this: Although the year was 2012, many small communities in east India lacked access to modern power; wood fires, kerosene lanterns, and human power were the only ways to get things done. However, the government—specifically, a state-level Energy Development Agency—offered to provide community-scale electrification through a new solar…
