Activities in Sierra Leone

Project for Urgent Improvement of Electric Power Supply System in Freetown – Phase I and Phase II

Background and Objective


The civil war in Sierra Leone from 1991 to 2002 severely affected its economy and society. Freetown's electric power sector, for example, is facing a serious lack of funding and reserve capacity, resulting in deteriorating power-generating facilities that cannot be properly maintained and do not have sufficient power capacity. This has resulted in many offices as well as industrial and commercial facilities compensating with inefficient home-type generators and a slowdown in economic development. The Power Supply Improvement Project for Freetown thus aims to build and maintain power-generating and power distribution facilities to achieve in reviving Sierra Leone's economy and improve the lives of the country's citizens.
