Sachi Graber

Senior Associate
  • SEED (Africa)

Sachi is a Senior Associate with RMI’s Sustainable Energy for Economic Development (SEED) program. SEED 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 SEED 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.
