The impact of solar home systems on rural livelihoods. Experiences from the Nyimba Energy Service Company in Zambia

An Energy Service Company (ESCO) in the town of Nyimba, Zambia, has been operating 100 solar home systems since the year 2000. The company is part of a pilot project implemented by the Government of Zambia with the aim to apply the ESCO concept for diffusion of solar technology. The change in livelihood as a result of the access to electric services has been investigated in a survey. Clients were satisfied with the services they receive, although they are paying more than previously for energy. Light hours did not increase, but the quality of light was improved, enabling activities such as domestic work at night and studying for longer hours. Many of the clients had acquired TV and video, and become part of a more global culture. Appliances for entertainment, such as video and TV, were considered more attractive than productive appliances such as a water pump by many respondents. In some cases also people from households without solar installations benefited from the installations, for instance, children gathering in houses with solar to study at night.
