Mini-hydro in Zambia

Shiwangandu 1 MW

In early 2013, RDC reported on evaluations of a range of renewable energy projects in Zambia for the United Nations, including the Shi’wangandu 1 MW mini-hydro project which was inaugurated by the President in December 2012.  This project in the east of the country was funded by ZESCO (93%) and the Global Environmental Facility (7%) coordinated by UNIDO and feeds a mini-grid benefiting over 2,000 people. RDC evaluated the impact of the project in terms of its demonstration that reliable power supplies based on renewable energy can be pursued in rural areas to promote income generation activities and contribute to the Zambian government’s efforts to reduce poverty.
