The purpose of this study is to provide practical guidance and recommendations to the Government of Sierra Leone for the sustainable development of the country’s mini-grid sector by building upon lessons learned from the ongoing Rural Renewable Energy Project (RREP) as well as from mini-grid sector development in Nigeria. Important lessons can be learned from the two countries with respect to their mini-grid policy and regulatory frameworks, market development approaches, and potential options for agricultural productive use of electricity (PUE) to facilitate both mini-grid electrification and rural economic development. The report, prepared by GreenMax Capital Advisors, also compares and highlights lessons learned from mini-grid sector development in Nigeria.
